[Asia Fluid Network News] China's fire pump used according to different types of use is not the same occasion. According to different occasions can be divided into: car fire pump, marine fire pump, engineering fire pump, medium pressure fire pump, low pressure fire pump. With the increasing use of fire pumps, fire pump liquid or lack of pressure this problem gradually appears, then the fire pump fluid or lack of pressure diagnosis. Fire pump fluid or lack of pressure diagnosis 1, the direction of rotation is not the elimination of measures: Check the direction of rotation. 2, Impeller or pipeline plugging Elimination measures: Check for any obstructions. 3, the end of the valve is too small Elimination measures: the correct size of the valve installed at the end. 4, pump no water or no exhaust to eliminate measures: Check the pump housing and inlet pipe are all filled with liquid. 5, the system head too high Elimination measures: Check the system head (especially the friction loss). 6, the air or inlet pipeline leaks Elimination measures: check the inlet pipeline for air cavitation and / or leakage. 7, stuffing box packing or seal wear, so that air leakage into the pump casing Elimination measures: Check the packing or seal and replace as needed to check the lubrication is normal. 8, pumping hot or volatile liquid inhalation head shortage Elimination measures: Increase the suction head, consult the manufacturers. 9, the speed is too low Elimination measures: Check the motor wiring is correct, the voltage is normal or the turbine steam pressure is normal. 10, suction stroke too high Elimination measures: check the existing net head. Through the above fire pump fluid or lack of pressure diagnosis and analysis, we can learn more about the fire pump to use some of the precautions, the equipment is often used not because of the equipment itself, but the user when using the device Do not pay attention, if the user can pay more attention to details and equipment protection during the use of the equipment, I believe this not only can play the role of equipment, but also can extend the service life of the equipment.
