The Problem Of No Water in Fire Pump Pipe And The Solution

Nov 23, 2023

Fire pump for the transport of solid particles do not contain water and physical and chemical properties similar to the water of the liquid, mainly used in fire systems, spray system pipeline pressurization water supply, can also be applied to industrial and urban water supply and drainage, high-rise building pressurization water supply, long-distance water supply, heating and other occasions. Fire pumps are different from ordinary equipment and do not need to be operated every day. Only turn it on when it really matters. When the fire pump that has been idle for a long time has no water in the pipeline, what is the main problem?

First, the speed is small, may be because the motor wiring is incorrect, or the steam pressure is abnormal and the speed is small, resulting in insufficient pressure to pump water.

Second, the fire pump forgot to inject water or did not exhaust properly.

 

Three, the fire pump suction is too high.

 

Fourth,Some parts of the fire pump that have been idle for too long are damaged, such as the impeller is damaged, the impeller clearance is larger, the pipeline is blocked, the pressure gauge position is offset, the inlet pipeline is leaking, and the lubricating oil is not enough.

 

Fifth, the bottom valve or inlet pipe of the fire pump is not submerged enough.
The fire pump pressure is insufficient, resulting in no water in the fire pump pipe, which can be large or small in the issue of fire safety. To this end, the Pacific Pump industry is particularly reminded that when buying fire pumps, do not forget the maintenance of fire pumps.
