Fire pump start and stop pump steps

[Asia Fluid Network News] fire pump according to different occasions, it is also different types. Commonly used fire pumps are more commonly used: fire hydrant pump, fire pump, fire booster pump, fire sprinkler pump. Although the fire pump types, but the fire pump start-stop pump operation steps and use the steps roughly the same, in order to facilitate the user to use such products, the next will be introduced fire pump start-stop pump steps. Fire pump start-stop pump steps 1, start the pump, check the motor operating current and pump operation is normal, if abnormal should immediately stop the pump. 2, look at the pump outlet pressure gauge, when the gauge pointer reaches the rated working pressure and stability, gradually open the outlet valve, try to make the pump work in rated condition. 3, the pump is normal water, vacuum suction clutch handle will be moved to the "sub" position. 4, Check the valve group pressure, the water pressure of the valve group insists about 0.8Mpa or so, the foam valve group insists about 1.0Mpa .If the pressure can not be insisted, the pump outlet and return valve can be properly adjusted to control the 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, after stopping the pump, press all the valves according to the valve open and close the state diagram request, return to normal state. 7, the vacuum suction clutch handle installed to move to the "position", open the air valve, so that the float assembly reset, in preparation for the state. 8, if the pump starts to pressure 0.8Mpa immediately after arriving back to 0.4Mpa or so, can not be normal water, this time to immediately stop the pump, open the air valve so that the float assembly reset, restart 9, under normal conditions , 1 #, 2 # pressure pump to ensure that one is in working condition, one in standby mode. Through the above fire pump start-stop pump operation steps analysis, we can clearly understand the working condition of the fire pump. Knowing the working status of a fire pump can be very helpful for the use of a fire pump, and we all know that the use of each kind of equipment and products requires the user's effort to exert the functional value of the equipment.
