Equipment maintenance and maintenance rules are used for equipment maintenance.

I. Maintenance of Equipment Maintenance of equipment by wiping, cleaning, lubricating, adjusting and other general methods to maintain and protect the performance and technical condition of equipment is called equipment maintenance.

There are four main requirements for equipment maintenance: (1) Clean the inside and outside of the equipment, and there is no oil leakage, oil leakage and air leakage on the sliding surface, screw, rack, gear box and oil hole, and the debris, sundries and dirt around the equipment should be cleaned up; (2) Tools, accessories and workpieces (products) should be placed neatly, and pipes and lines should be organized; (3) Good lubrication, timely refueling or oil change, no dry friction. The oil pressure is normal, the oil mark is bright, the oil path is smooth, the oil quality meets the requirements, and the oil gun, oil cup and linoleum are clean; (4) Abide by the safety operation rules, do not overload the equipment, complete and reliable equipment safety protection devices, and eliminate unsafe factors in time. Equipment maintenance generally includes daily maintenance, regular maintenance, regular inspection and precision inspection, and the maintenance of equipment lubrication and cooling system is also an important part of equipment maintenance.

Daily maintenance of equipment is the basic work of equipment maintenance, which must be institutionalized and standardized. Regular maintenance of equipment should establish labor quota and material consumption quota, and conduct assessment according to the quota. Regular maintenance of equipment should be included in the assessment of workshop contract responsibility system.

Regular inspection of equipment is a planned preventive inspection. In addition to human senses, there must be certain inspection tools and instruments, which are carried out in the checklist regularly. Regular inspection is also called regular spot check. The accuracy of mechanical equipment should also be checked to determine the actual accuracy of the equipment.

Equipment maintenance should be carried out according to the maintenance procedures. Equipment maintenance procedures are the requirements and regulations for daily maintenance of equipment. Compliance with these requirements can prolong the service life of the equipment and ensure a safe and comfortable working environment.

Its main contents shall include: (1) operation contents, operation methods, tools and materials used, neat, clean, firm, lubricated, anticorrosive and safe standards and precautions; (2) the parts, methods and standards of daily inspection, maintenance and regular inspection; (3) Check and evaluate the contents and methods of the operator's degree of equipment maintenance. Second, the three-level maintenance system of equipment The three-level maintenance system is a maintenance system that was gradually improved and developed in China in the mid-1960 s on the basis of summarizing the practice of the planned pre-maintenance system of the former Soviet Union. It reflects the shift of the focus of equipment maintenance management in China from repair to maintenance, the progress of equipment maintenance management in China and the clearer maintenance management policy of prevention first.

The three-level maintenance system includes daily maintenance, first-level maintenance and second-level maintenance of equipment. Three-level maintenance system is a mandatory maintenance system with operator as the center and equal emphasis on equipment maintenance.

Three-level maintenance system is an effective way to rely on the masses, give full play to their enthusiasm, implement group management and group maintenance, and combine special groups to do a good job in equipment maintenance. (I) Daily maintenance of equipment Daily maintenance of equipment generally includes daily maintenance and weekly maintenance, also known as daily routine maintenance and weekly routine maintenance.

1. The daily operation is guaranteed by the equipment operator on duty, and four things are done before class, five things in class and four things after class. (1) Arrange the pattern data of four things before the shift change, and check the shift change records.

Wipe the equipment, and lubricate and add oil as needed. Check whether the handle position and manual operation position are correct and flexible and whether the safety device is reliable.

Check whether the transmission is normal and whether the lubrication and cooling are smooth when running at low speed. (2) Pay attention to operating sound, equipment temperature, pressure, liquid level, electrical, hydraulic and pneumatic systems, instrument signals and safety insurance.

(3) Turn off the four-object switch after work, and set all handles to zero. Remove iron filings and dirt, clean the oil stains on the guide rail surface and sliding surface of the equipment, and refuel.

Clean up the work site, arrange accessories and tools. Fill in the handover record and operation time record, and go through the handover procedures.

2. Equipment operators shall conduct weekly maintenance once every weekend, with the general equipment maintenance time of 2h and the maintenance time of fine, large and rare equipment of 4h. (1) Externally clean the guide rail, transmission parts and exposed parts of the equipment, and clean the work site.

Achieve cleanliness inside and outside, no dead ends and no rust, and the surrounding environment is clean and tidy. (2) Control the transmission to check the technical condition of each component, tighten loose components and adjust the fit clearance.

Check interlocking and safety devices. Transmission sound is normal, safe and reliable.

(3) Hydraulic lubrication cleans the oil circuit, dust cover and oil filter, and adds oil or changes oil in the oil tank. Check the hydraulic system to ensure that the oil quality is clean, the oil circuit is smooth, there is no leakage and no wear.

(4) The electrical system should wipe the surface of the motor and the snake skin tube, and check the insulation and grounding to achieve completeness, cleanliness and reliability. (II) First-level maintenance The first-level maintenance is mainly based on operators. With the assistance of maintenance workers, the equipment is partially disassembled and inspected as planned, the specified parts are cleaned, the oil lines and pipelines are dredged, the oil lines, blankets and oil filters are replaced or cleaned, the fit clearance of each part of the equipment is adjusted, and each part of the equipment is fastened.

The first-class maintenance time is 4-8 hours. After the first-level maintenance is completed, records shall be made and the uncleared defects shall be indicated, and the workshop mechanic shall organize the acceptance. The scope of the first insurance should be all the equipment in use of the enterprise, and the key equipment should be strictly implemented.

The main purpose of the first warranty is to reduce equipment wear and tear, eliminate hidden dangers, prolong the service life of equipment, and provide guarantee for the completion of production tasks until the next first warranty period. (3) Secondary maintenance Secondary maintenance is mainly completed by maintenance workers and operators.

Incorporate the secondary maintenance into the equipment maintenance plan, partially disassemble, inspect and repair the equipment, replace or repair worn parts, and clean, change oil, inspect and repair electrical parts, so that the technical condition of the equipment can fully meet the requirements of the specified equipment integrity standards. The second maintenance takes about 7 days.

After the second guarantee is completed, the repairman should fill in the maintenance records in detail, which will be accepted by the workshop mechanics and operators, and the acceptance sheet will be submitted to the equipment power department for filing. The main purpose of the second maintenance is to make the equipment reach the intact standard, improve and consolidate the intact rate of the equipment, and extend the overhaul period.

To implement the "three-level maintenance system", operators must achieve "three good", "four meetings" and "four essentials" and abide by "five disciplines". The three-level maintenance system highlights the maintenance in equipment management.

What is the key to equipment maintenance?

From the perspective of equipment life cycle, the use, maintenance and repair stages of equipment account for the vast majority of equipment life cycle, which is the guarantee stage for equipment to truly play and reflect its use value.

This paper first studies the economic benefits of compulsory maintenance of tunnel construction machinery and equipment, then discusses the enlightenment of domestic advanced maintenance systems and methods to the maintenance of tunnel construction machinery and equipment, and on this basis, puts forward the measures to implement compulsory maintenance of machinery and equipment. Keywords: architecture; Machinery; Maintenance Introduction Tunnel construction has the characteristics of large quantities, heavy tasks, high investment, tight construction period and strong seasonality. For tunnel construction machinery and equipment with harsh working conditions all the year round, it is particularly necessary to maintain the equipment.

According to the decomposition diagram of common main failure factors of construction machinery, 56% of the main failures of construction machinery are caused by the problem of loss of insurance and nutrition, 38% by regular maintenance errors and 6% by mechanical operation errors. Relevant statistics show that the annual mechanical maintenance cost of a company accounts for 17.6% of the mechanical construction output value, and nearly 60% of the maintenance cost is caused by the loss of insurance and maintenance, the early wear and tear of parts and components and the shortening of service life. For a wide variety of tunnel construction machinery and equipment with wide coverage, the annual mechanical maintenance cost accounts for a high proportion of the mechanical construction output value.

At the same time, from the perspective of equipment life cycle, the use, maintenance and repair stages of equipment account for the vast majority of equipment life cycle, which is the guarantee stage for equipment to truly play and reflect its use value. Therefore, it is necessary and imperative to vigorously promote the compulsory maintenance of tunnel construction machinery and equipment.

1, the economic benefit of compulsory maintenance of tunnel construction machinery and equipment. The premise and basis for completing the construction production task on schedule and with high quality is the good operation of machinery and equipment, and equipment maintenance is to scientifically maintain and maintain the machinery and equipment according to the objective laws of the machinery and equipment itself, so as to reduce the wear rate of mechanical parts and prevent the occurrence of faults, so as to keep the machinery and equipment in good condition, give full play to the mechanical efficiency and maximize the service life of the machinery and equipment. Under the current law of market economy, the competition among enterprises is becoming increasingly fierce, while modern equipment is capital-intensive equipment, and the investment and use cost of equipment are very expensive. Construction enterprises pay attention to operating results and urgently demand to improve the economic benefits of equipment management.

Only by doing a good job in the maintenance of mechanical equipment, improving the intact rate, utilization rate and productivity of equipment, reducing the maintenance costs and other abnormal costs in the life cycle of equipment, reducing the use cost and prolonging the service life, can the investment benefit be further improved. On the surface, enterprises have to pay for the maintenance of machinery and equipment, but from the overall situation and long-term interests, there are the following points: 1. 1 Simple technical requirements and low cost, while ensuring the normal operation of equipment, reducing the wear and tear of parts and prolonging the service life of equipment. Especially for large and imported major machinery, it is necessary to strengthen the necessary technical maintenance operation, eliminate hidden dangers and ensure the normal operation of equipment.

For example, the main tunnel excavation equipment, such as rock drills, loaders, large dump trucks, etc., is German equipment produced by 1888. Due to high energy consumption, 1988 stopped using it and used it for 100 years. Baocheng double track, which was built by China Railway 15th Bureau, only operated for more than 3,000 hours and had to be overhauled in advance. From the comparison between the two, it can be seen that maintenance not only ensures the completion of the production task of engineering construction, but also reduces a lot of unnecessary costs and greatly improves the economic benefits of enterprises.

1.2 The shorter the service life of the equipment, the higher the reliability, and the longer the service life, the lower the reliability. The lower the reliability, that is, the mechanical equipment is prone to failure, the more serious the physical wear and tear of the equipment, and the greater the maintenance cost.

Modern mechanical equipment is capital-intensive equipment, and the equipment investment and use cost are very expensive, which urgently needs the economic benefits of equipment management. Therefore, it is necessary to reduce the tangible loss of equipment and reduce the maintenance cost and other abnormal expenses in the whole life cycle of equipment through maintenance and maintenance.

Enable enterprises to allocate limited resources more scientifically and reasonably, and at the same time achieve the purpose of "reducing expenditure and increasing income". Otherwise, overhaul or replacement of new equipment will undoubtedly increase the cost of enterprises, affect the economic benefits of enterprise resources, and more likely affect the construction at any time, and even affect the reputation and credibility of enterprises.

For example, when the bridge erecting machine breaks through the key construction period, it will lose 5-7 beams in one day, and the loss is immeasurable. 2. Maintenance methods of construction machinery and equipment in China First of all, Guangxi Yulin Diesel Engine Factory began to implement the "strong repair and zero waiting" system from 1994, which improved the reliability of diesel engines from 30,000 km to 65,438+100,000 km.

The main contents of the project are as follows: with "strong maintenance" as the core, 64 kinds of equipment integrity standards and operation and maintenance procedures with producers as the main body have been revised and implemented, and management systems such as maintenance procedures for major production equipment (including imported equipment) have been stipulated; Software and hardware supplement and perfection with "zero waiting" as the core and radiation equipment maintenance personnel as the implementation theme. "Zero waiting" means that when waiting for maintenance personnel, waiting for maintenance spare parts, waiting for maintenance tools and waiting for maintenance information, the problem is zero.

"Strong Zero Project" also has high reference value for tunnel construction enterprises. Secondly, China Railway 19th Bureau Group and other units have also gained good experience in promoting the compulsory maintenance of mechanical equipment.

3, the implementation of compulsory maintenance measures for machinery and equipment In view of the current situation of construction machinery and equipment maintenance and the new characteristics and new situation of construction enterprises, China has put forward a compulsory maintenance system for machinery and equipment. For tunnel construction enterprises, if they want to improve their market competitiveness under the conditions of market economy, they must have high construction efficiency and high economic benefits.

The maintenance of machinery can improve the efficiency, but how to minimize the maintenance cost and finally achieve the optimal economic benefits of enterprises under the premise of ensuring the use efficiency is a realistic problem that all tunnel construction must face. The author summarizes several suggestions through long-term practical exploration, hoping to get the correction from peers. 3. 1 Improve the recognition.

Consultation: equipment maintenance

Regional maintenance of equipment is also called maintenance package mechanism.

The repairman undertakes the maintenance of equipment in a certain production area, completes the daily maintenance, patrol inspection, regular maintenance, planned maintenance and troubleshooting together with the production operators, and is responsible for completing the assessment indicators such as the equipment intact rate and fault shutdown rate in the area. Regional maintenance responsibility system is a good form to strengthen the maintenance of production equipment, mobilize the enthusiasm of maintenance workers and make production workers take the initiative to care about equipment maintenance.

The main organization form of equipment professional maintenance is regional maintenance group. The regional maintenance team is fully responsible for the maintenance and emergency repair of equipment in the production area. Its tasks are: (1) to be responsible for the maintenance and repair of equipment in this area, and to ensure the completion of equipment integrity rate, failure rate and other indicators; (2) Seriously implement the system of regular spot inspection and regional inspection of equipment, and guide and urge operators to do daily maintenance and regular maintenance; (3) Under the guidance of workshop mechanics, participate in equipment condition investigation, precision inspection, adjustment, leakage control, and conduct fault analysis and condition monitoring.

As an organizational form of equipment maintenance, the regional maintenance team has the advantages of high mobility when completing emergency repair, which can minimize the downtime of equipment maintenance, and the locksmith on duty can complete various preventive operations and participate in planned maintenance without being called. The division of equipment maintenance area should consider the distribution of production equipment, equipment status, technical complexity, production needs and the technical level of assemblers.

Workshop equipment can be divided into several areas according to the above factors, and regional maintenance groups can also be divided according to equipment types. The equipment of the assembly line should be divided into maintenance areas according to the production line.

The regional maintenance team shall make a plan for regular inspection and accuracy inspection, and specify the time for routine inspection of equipment in each shift. In order to make these work not affect the production, the planned inspection of the equipment should be arranged in the non-working days of the factory, and the routine inspection of each shift should be arranged during the lunch break of the production workers.

How to do a good job in the maintenance of equipment.

Equipment maintenance includes: daily maintenance, primary maintenance and secondary maintenance.

Three-level maintenance system is a mandatory maintenance system with operator as the center and equal emphasis on equipment maintenance. Three-level maintenance system is an effective way to rely on the masses, give full play to their enthusiasm, implement group management and group maintenance, and combine special groups to do a good job in equipment maintenance.

What is equipment maintenance? Why do you need to maintain the equipment?

Through the maintenance of mechanical and electrical equipment, the operating efficiency of the equipment can be effectively improved, the service life of the equipment can be prolonged, and the loss of the equipment can be reduced, thereby improving the productivity and reducing the production cost.

1) Equipment management is the basic work of enterprise production and operation management.

Equipment management is the basis of leasing operation and improving enterprise efficiency. Construction machinery and equipment are the material basis for the production and operation of construction machinery leasing enterprises. The continuity and balance of mechanical construction mainly depend on the normal operation of mechanical equipment. Only by strengthening equipment management, correct operation and use, careful maintenance and monitoring of equipment conditions, scientific maintenance and transformation of equipment, and keeping equipment in a good technical state, can we ensure the sustained and stable operation of production. On the other hand, if the equipment management is neglected and the maintenance, inspection, repair and transformation are relaxed, the technical condition of the equipment will be seriously deteriorated, and the equipment will run with diseases, which will inevitably lead to many failures and it is difficult to ensure the timely completion of the construction plan. For construction enterprises (lessees), in addition to the rental price of equipment, they also began to care about the quality and management of services. Leasing enterprises should adopt perfect equipment management measures to ensure the safe and reliable operation of leased equipment, which will not affect the construction and satisfy users. Service is important, but ensuring the normal use of equipment is what users expect.

2) Equipment management is an important way to improve the economic benefits of enterprises.

Equipment management is the premise for leasing enterprises and mechanical construction enterprises to complete construction tasks and ensure quality, efficiency and delivery time. Equipment management not only affects the output and quality of construction projects, but also affects the investment (maintenance, oil consumption, etc.) of enterprises. ), so it is an important factor affecting the economic benefits of enterprises. Therefore, strengthening equipment management is an important way to tap the production potential of enterprises and improve economic benefits. If there is no high-level equipment management and good equipment running status as a guarantee, it is not III's good performance of the contract. Once breach of contract, it will not only bring economic losses to enterprises, but also often lose the market, which will have a serious impact on the development of enterprises. Equipment management should ensure the use of construction machinery. III and operational reliability. Once the construction machinery in construction breaks down, resulting in production interruption, it will cause economic losses, delay the construction period, and sometimes cause huge economic losses. In highway construction, if the paver fails and stops working, it will cause a lot of waste of materials and increase the construction cost; When pouring concrete, the concrete construction equipment fails to stop pouring, which will seriously affect the engineering quality and cause economic losses.

3) Equipment management is the premise of safe production and environmental protection.

Equipment management is the guarantee of enterprise's safe production. Backward equipment technology and poor management are important reasons for equipment accidents, personal injuries and environmental pollution. Safe production and clean environment are the long-term interests of human survival and social development. Leasing enterprises must attach importance to equipment management and create a good premise for safe production and environmental protection. Many modern machinery and equipment operate at high speed, high load, high temperature and high pressure. Once an accident happens, it will easily cause equipment damage, casualties and environmental pollution, leading to serious consequences. Safety in production is the premise for enterprises to do a good job in production and operation. Without safe production, all work is in vain. Therefore, all levels and departments, from the central to the local, are emphasizing safety in production and paying close attention to safety in production. Safety in production is mandatory and must be unconditionally observed. Any production and operation activities of an enterprise must be based on safe production. To ensure safe production, there must be well-functioning equipment, and good equipment management will eliminate most hidden dangers of accidents and avoid most safety accidents.

4) Equipment management is an important condition for the long-term development of enterprises.

Scientific and technological progress is the main driving force to promote economic development. In order to survive and develop in the fierce market competition, enterprises need to constantly adopt new technologies and create new achievements. All these require strengthening equipment management, promoting the technical progress of production equipment, ensuring the smooth completion of construction projects with advanced construction equipment and good equipment status, and realizing the long-term development goals of enterprises. It can be seen that equipment management not only directly affects the current production and operation of leasing enterprises, but also relates to the long-term development and success or failure of enterprises. The leaders of leasing enterprises must put modern equipment and its management in the correct position of the enterprise, be good at constantly improving the quality of personnel and equipment, give full play to the efficiency of equipment, and create the best economic and social benefits for the enterprise.

12. Take corresponding countermeasures and measures to improve the technical condition of the equipment. Improve standards and systems, and constantly improve the management level of equipment technical status.

Equipment maintenance system

Equipment is one of the three elements of productivity and the material data of social production. The quality of equipment management has a decisive influence on the economic and technical indicators such as the quantity, quality and cost of enterprise products. Therefore, we should strictly follow the operating rules of the equipment, do a good job in the correct use of the equipment, carefully maintain and scientifically maintain it, and strive to improve the intact rate of the equipment. To this end, the following equipment maintenance system is formulated:

First, the operators and maintenance (inspection) personnel should use the equipment correctly and maintain it carefully with a serious attitude and scientific methods. Adhere to the principle of paying equal attention to maintenance and overhaul, and giving priority to maintenance and expansion. Strictly implement the post responsibility system and implement the equipment package mechanism to ensure that the equipment in use is in good condition.

Second, operators should know four things and three things about the equipment they use through on-the-job training and learning technology (understanding the structure, performance and use; All use, maintenance and troubleshooting), and enjoy three rights, namely: the right to automatically prevent others from using their own equipment; Have the right to stop using the equipment if it is overloaded, without preventive measures or without the approval of the main customer department. If it is found that the equipment is not working normally, it is not repaired within the time limit, and the safety device does not meet the requirements, it should be reported immediately. Do not immediately deal with and take corresponding measures, have the right to stop using.

Three, the operator, must do the following main work:

(1) Use the equipment correctly, strictly abide by the operating procedures, carefully prepare before starting, check it repeatedly when starting, properly handle it after stopping, make adjustments during operation, and earnestly implement various operating indicators. Overtemperature, overpressure, overspeed and overload operation are strictly prohibited.

(2) Seriously maintain and strictly implement the patrol inspection system, use the five-character operation method (listening, wiping, smelling, watching and comparing), and hold three treasures (wrench, stethoscope and rag). Check the equipment regularly according to the patrol inspection route, find problems, solve them in time, and eliminate hidden dangers. Do a good job in cleaning, lubricating, fastening, adjusting and anticorrosion of equipment (that is, cross operation method). Keep parts, accessories and tools intact.

(3) master the prevention, judgment and emergency treatment measures of equipment failure, and keep the safety protection device in good condition.

(4) The equipment is planned to run and switched regularly. Cooperate with maintenance personnel to maintain the standby equipment, so that it is always in good condition and can be started at any time. Spare equipment should be rotated regularly, and anti-freezing and anti-coagulation work should be done well.

(5) Fill in the equipment operation record, defect record and operation diary carefully.

(6) Always keep the equipment and environment clean and hygienic, so that the bottom of the ditch and the shaft can see the light, the equipment can see its true colors, and the doors and windows are clean.

Fourth, do a good job in equipment lubrication. Strictly implement the lubrication management system of petrochemical equipment and adhere to the five-fixed and three-level filtration (five-fixed: fixed point, fixed time, fixed quality, fixed quantity and fixed personnel; Three-stage filtration: from the oil receiving barrel to the rear oil storage barrel, from the rear oil storage barrel to the oil tank, and from the oil tank to the refueling point). At the same time, the lubricating parts and oil tanks should be cleaned and replaced regularly.

Five, the operator must conscientiously implement the system of succession.

Six, equipment maintenance personnel for the maintenance of equipment, should be on time for inspection tour, found that the problem handled in time, cooperate with the operator to do a good job in production safety.

Seven, workshop maintenance of all equipment, pipelines, etc., must have a clear division of labor, and timely do a good job of antifreeze, anticoagulation, heat preservation, cold preservation, anti-corrosion, plugging and so on.
