Then the fire pump to have what conditions are qualified, what are the conditions in line with acceptance requirements, the current Xiaobian interpretation for you one by one. Fire pump acceptance conditions to know how many First, the fire pump, spare pump, suction pipe, outlet pipe and outlet pipe pressure relief valve, water hammer elimination facilities, check valves, signal valves and other specifications, models, the number should be consistent with the design Requirements; suction pipe, the control valve on the outlet pipe should be locked in the normally open position, and clearly marked; Second, fire pumps should be self-filling water diversion reliable and ensure that all water is effectively used. Third, respectively, open the system in each end of the test water test device and test valve, flow indicator, pressure switch, low pressure switch, high fire water tank fire and other functions are in line with the design requirements. Fourth, open the fire pump outlet pipe test valve, when using the main power to start the fire pump, the fire pump should start normal; turn off the main power, the main and backup power should be able to switch normally. Fifth, the fire pump to stop pumping, water hammer eliminate the pressure after the facility should not exceed the pump outlet rated pressure of 1.45 times. Sixth, the fire pressure water supply equipment, when the system pressure drops to the design of the lowest pressure, the pressure change signal should start the pump. Seven, fire pump start control should be placed in the automatic start gear. Eight, fire pumps using fixed and mobile flow meters and pressure gauges to test fire pump performance, pump performance to meet the design requirements. Check quantity: check all. Inspection methods: observation inspection and instrumentation. The above is the fire pump meet the acceptance requirements of the eight conditions, I hope your understanding and learning to provide some help.
