Fire pump operation, must be strictly in accordance with fire pump operating procedures to ensure safety and normal operation. Fire pump operating procedures are divided into three parts, first, before the start of the inspection, the second is the operation process, the third is the latter part of the maintenance. Next, the world factory valve network for everyone to detail. Fire pump operating procedures the main purpose is to ensure the safety and correctness of the operation, the procedures applicable to the building's fire-fighting equipment. First, the pre-start inspection 1, check the process of valve switching, the corresponding return valve switch conditions are met. (1) In the daily test pump, the return valve should be fully open, the valve set in the closed position valve. Try 1 # foam pump, 2 # pump foam exit need to close the Vp111, Vp112, Vp212 three foam tank inlet valve, open the Px021 return valve to pump; trial 2 # pump water outlet, 3 #, 4 # fire pump Need to open the Px011 back to open the pump when the pump. After the test pump all valves will be restored to the prescribed state. (2) In the event of an emergency or a fire drill, when the water needs to be discharged, open the valve of the valve group where the corresponding fire-fighting water (foam) is required and the return valve is closed. (3) The pump inlet valve must have a normally open outlet valve in the closed position. 2, check the vacuum suction device clutch handle should be in "close" position. 3, open the deflation valve, float valve assembly to close the deflation valve after reset. Second, start and stop the pump Operating steps 1, start the pump, check the motor running current and pump operation is normal, if abnormal should immediately stop the pump. 2, observe the pump outlet pressure gauge, when the gauge pointer reaches the rated working pressure and stability, and gradually open the outlet valve, try to make the pump work in rated condition. 3, the pump normal water, vacuum device will clutch handle move to "points" position. 4, observe the valve group pressure, water pressure in the valve group maintained at about 0.8Mpa, foam valve group remained at about 1.0Mpa. If the pressure can not be maintained, you can adjust the pump outlet and return valve control pressure. 5, should always check the temperature of the pump and motor bearings, the maximum temperature can not exceed 75 degrees, check the motor operating current should be within the normal range. 6, stop the pump, all valves according to the valve on and off state diagram requirements, return to normal condition. 7, the suction device vacuum clutch clutch handle to "close" position, open the air release valve, so that the float assembly reset, in preparation for the state. 8, if the pump starts to return to 0.4Mpa immediately after the pressure reaches 0.8Mpa, can not be normal water, then immediately stop the pump, open the deflation valve so that the float assembly reset, restart. 9, under normal circumstances, 1 #, 2 # pump to ensure that a state of work, one in a standby state. Third, maintenance and repair 1, each class to check and ensure the fire power system, the circuit is unobstructed, electrical equipment intact. 2, each plate pump once, the coupling should be light and uniform, no abnormal sound and make a record. 3, every month 5, 10, 15, 20, 25, 30 inspection vacuum suction device bit, the location of the oil in the center line or slightly below the center line; start the fire pump, check the pump water Time and make a record, 1 #, 2 # pump run for 15 minutes, 3 #, 4 # pump run for 5 minutes. 4, after the start of the pump check the float assembly operation, the exhaust hose should not have water. If there is water, you must replace the float seal. 5, after the pump starts to check the size of vacuum suction device sealed body is tight, the exhaust is normal. 6, check the packing seal after the pump starts, the leak should not exceed 10-30 drops / min. 7, regularly check the various parts of the pump lubricant to ensure lubrication system is working properly. 8, regularly check the connection site is fastened, with or without loose. The fire A, B pool level remained at 3.45m from the bottom of the pool, the new 1700m3 fire pool to ensure that 70% of the water.
