No, it's normal.
7. Maintenance of linkage system (image monitoring linkage): it shall be cancelled at least once a year.
The automatic test of fire control equipment was simulated 1 ~ 3 times, and the control display function of fire control equipment was tested.
Maintenance operation procedures of fire water supply system
1, nozzle maintenance (excluding oil stains, paint, etc. On the nozzle):
Check the nozzle appearance once a month (not less than 10%), and replace the nozzle in time if it is abnormal; When there is a foreign body on the nozzle, it should be removed and replaced in time.
2, pipeline system maintenance:
(1) Observe the starting frequency of the pressure stabilizing pump to determine whether there is leakage in the pipe network.
① Appearance inspection: check whether the pipeline has mechanical damage, paint peeling and corrosion.
Whether the pipeline is firmly fixed, and handle the problems in time when found.
② Clear the blockage: There may be some residual sand, stones and sawdust in the system pipeline.
Or the garbage and rust brought by the water source will cause the nozzle to be blocked, the alarm valve to be closed loosely, and the water pipe of the hydraulic alarm bell to be blocked.
(2) Drain at least 20% of the pipe end every month to ensure the good water quality in the pipe, and check the alarm function of the water flow indicator.
3, alarm valve maintenance:
The valve opening test shall be conducted for the alarm valve to observe the opening performance and sealing performance of the valve, and whether the working conditions of all parts of the alarm valve are normal; The drainage test valve next to the alarm valve should be tested every quarter to verify whether the water supply capacity of the system and the alarm function of the pressure switch are normal. The installed pressure gauges should be checked regularly. Check whether the indication of the rear pressure gauge is normal before alarming.
4. Maintenance of air pressure tank:
(1) Open the exhaust valve and check whether it can automatically pressurize.
(2) Open the test drain valve and check whether the water supply can be automatically pressurized when reducing water.
And whether the pressure gauge of the water supply device shows normal.
(3) When opening the drain valve of the exhaust valve type test, the valve should be opened slowly to prevent the high pressure in the pneumatic water tank from causing danger.
5, water and fire pump room maintenance:
(1) The interface and accessories of the fire pump adapter shall be inspected once a month. The interface shall be intact, without leakage, covered completely, and firmly connected with the cover plate. (2) Check whether the water level of the fire pool can keep the fire water consumption; Whether the water level gauge works normally; Whether the pool valve is in normal condition; Do you have a cold?
This possibility.
(3) Check whether the water quantity of the fire water tank meets the requirements; Whether the fire air pressure water supply device can guarantee the water quantity and water pressure; Whether the automatic control system can work normally. and
Measures to ensure that fire water is not used for other purposes should be checked and found that
Safety, should be handled in time.
(4) Whether the water level gauge and pressure gauge work normally and whether the pointer of the pressure gauge is correct. (5) The water supply capacity of water source should be determined once a year; In the outdoor valve well, the control valve on the water inlet pipe should be checked once a quarter to verify it.
No is fully open.
(6) Every two years, fire water storage equipment shall be inspected, repaired and repainted. (7) Maintenance of fire pump:
(1) Check whether the power operation of the fire pump is reliable and whether the pump can operate normally.
Whether the flow and pressure can be guaranteed; Whether there are facilities to ensure uninterrupted power supply,
Whether its performance is good;
The fire pump should be started and operated 1 ~ 3 times a month; When the fire pump is started by automatic control, it should start running 1 ~ 3 times a month under the condition of simulating automatic control.
(2) manual and automatic control to start the water pump 1 ~ 3 times, check whether the signal is feedback, whether the water pressure rises, and whether the motor rotates normally. Whether there is deformation, fever, etc. Whether the shaft, motor and connecting parts are loose, rusted, deformed and heated, and whether to refuel.
(3) whether the main pump and standby pump can automatically switch.
(4) Start the water pump, open the test valve, and check the pressure and flow with the flowmeter.
Pay attention to the open and closed state of each valve before moving.
⑤ Whether the pressure gauge is deformed after starting and whether the water pump operates normally.
⑥ The fire pump shall be overhauled once every two years, and lubricating oil shall be added to clean up the internal impurities. (8) Maintenance of control cabinet:
① The electric control cabinet is free from deformation, damage and corrosion.
② Whether the circuit diagram and operating instructions are complete.
(3) Whether the voltage and ammeter pointer are within the specified range.
(4) Whether the switch is deformed, damaged, the sign falls off and is in a normal state.
⑤ Whether the relay falls off or is loose, whether the contacts are burnt out, and whether the changeover switch should be switched.
In a dynamic state.
6. Control panel indicator light is normal.
All landowners wire connector is loose, whether the foreskin is damaged.
(9) Maintenance of water pump motor:
(1) Whether the lubricating oil of motor bearing is sufficient, and whether there is serious dirt or deterioration.
