Major insurance items of the year:

A. the host part of the ontology

Thoroughly clean the smoke pipe, water pipe, front and rear smoke boxes, furnace parts, burnout room and smoke pipe dust collection.

1. Open the cover completely, check the sealing integrity of inspection holes such as hand holes and manholes, and replace defective gaskets in time.

2. Check the overall instruments and valves, including pressure gauges, pressure controllers and electrode water level controllers, and set up safety valves.

B. Burner parts:

Thoroughly clean the burner rotor disc, ignition device, filter, oil pump, motor and impeller system, and add lubricant to the damper connecting rod device. Re-test the combustion.

C. control part

Overhaul and test electrical components and control lines, clean up the dust in the control box, and test at each control point.

D. water supply system

Overhaul the water treatment device, check whether the water quality meets the standard, comprehensively clean the soft water tank, check the operation and head of the feed pump, and clean the check valve core.
