The inspection process before the hot water boiler starts, specifically speaking, there are the following steps.
Step one: Check whether the safety accessories, thermal instruments and electrical instruments in the boiler are complete and intact, and can work normally.
Step 2: Check the connections, welds and pipelines of the hot water boiler for water leakage and other phenomena.
Step 3: Check whether the sewage line, inlet line and return line are unblocked.
Step 4: Fill the expansion and replenishment tank with water, and check the line voltage to see if its voltage is 380V. If there is a dial, whether it is controlled within 5%.
Step 5: Open the manual valve, as well as the water supply and return valves. After that, start the pump and burner, and check whether they are operating normally.
Step 6: Perform water filling operation on the boiler heating system in order to exhaust the air in the system without any residue. What are the specific inspection procedures in the operation of gas hot water boilers?
Gas hot water boiler is a type of hot water boiler. The inspection process in operation mainly includes the following points:
Process 1: Check the outlet and return water temperature of the gas hot water boiler, whether it is within the normal range. And, whether the pressure of the boiler is normal and stable, and whether its combustion condition is good.
Process 2: Check the make-up water pump and backup water pump, mainly to see whether it is running normally. And, to check the boiler water quality, whether it meets the specified standards in specific parameters. In addition, sewage should be carried out every day to remove scale in the boiler.
