How to repair the broken fire hydrant door?

Find someone to fix it at home. Municipal fire hydrants shall be installed and maintained by the administrative department of water supply of the government and used by the fire fighting forces. We found that the damage can be reported to the water supply administrative department and repaired in time.

The property management company will check the fire-fighting equipment every month and conduct fire drills every three months or half a year. If the fire hydrant or fire extinguisher is found to be faulty during maintenance and needs to be replaced, it is usually the property company's expense.

Solve the problem of unstable pressure of indoor hydrant air pressure water supply device;

First, check whether the pressure stabilizing pump of indoor hydrant water supply device works normally. Close the maintenance valve connecting the pneumatic water supply device with the system, manually start the pressure stabilizing pump, and observe whether the pressure of the pneumatic water supply device rises. If the pressure rises, it means that the pressure stabilizing pump has no problem and can work normally; If it doesn't rise, it means there is something wrong with the pressure stabilizing pump. Check whether the suction pipe of the pressure stabilizing pump is blocked, whether the motor is running and whether there is any problem with the pump.

Check whether the check valve leaks: stop the pressure stabilizing pump and observe whether the pressure of the pneumatic water supply device drops after a period of time. If the pressure of the pneumatic water supply device does not drop, it means that the one-way valve does not leak; If the pressure of the pneumatic water supply device drops, it means that the check valve leaks. Check whether the pneumatic tank works normally: slightly open the maintenance valve connected with the pneumatic water supply device and the system, and observe that the pressure of the pneumatic water supply device drops slowly. If the descent is slow, it means that the pressure tank is working normally.

Check whether the pressure stabilizing pump can start and stop automatically: slightly open the maintenance valve connected to the pneumatic water supply system or the safety valve of the pneumatic water supply device to reduce the pressure of the pneumatic water supply device to the lower limit, and the pressure stabilizing pump should start the pump; When the water is cut off, the pressure should rise. When the pressure reaches the upper limit, the pressure stabilizing pump will stop. If the above actions are correct, it means that the pressure stabilizing pump can start and stop automatically.
