The role of industrial boilers is reflected in all aspects, such as disinfection and sterilization in hospitals, chemical production, and so on. Various industries have demands for the use of industrial boilers. Zhengzhou Fangkuai Boiler Factory reminds everyone that if you want to ensure the stable operation of industrial boilers, routine maintenance work cannot be ignored.
Weekly maintenance work for industrial boilers:
1) To stop the furnace at ultra-low water level, perform a furnace shutdown test (press the button on the B3 board, it should be able to simulate a water shortage and stop the furnace), or blow the sewage to check the function of the furnace at ultra-low water level.
2) The safety valve is manually opened once and reset quickly.
3) The burner control system and the electric eye should be checked. The photocell of the electric eye should be pulled out by hand, and the furnace should be shut down within 1s; and the electric eye should be wiped.
4) Fill or replace the valve packing; eliminate dripping.
5) Tighten bolts everywhere, especially the gas pipeline system, and check for leaks if necessary.
Maintenance work to be done on industrial boilers every month:
Clean the filter on the gas line once a month.
Maintenance work to be done on industrial boilers every six months:
1) Check the pressure gauge and clean the gauge tube, add distilled water when resetting.
2) Maintain the water level electrode and polish it with fine sandpaper after pulling it out.
3) Clean up the flue, generally according to the exhaust temperature to decide whether to clean up. Under normal circumstances, the exhaust gas temperature does not exceed 350°C (measured at the exit of the boiler and the entrance of the flue). Too high means that the fouling increases and the efficiency of the boiler decreases, and it must be cleaned. The purpose of cleaning the flue is on the one hand for economic considerations, on the other hand it is also for safety considerations (the smoke fouling is poor in heat conduction and prone to local burning). When cleaning and replacing asbestos gaskets, use the method of lap joints (to prevent fumes from running out), and apply graphite instead of lubricating oil.
4) After boiler repair or annual inspection, check that the manhole, head hole, and hand hole nut are not loose, and check the rotation of the motor (from the fan end, it rotates counterclockwise).
Maintenance work to be done on the boiler each year:
Check the safety valve once a year. Perform a comprehensive overhaul and maintenance of the boiler.
