How to solve the leakage problem of fire pump?

The installation of the fire pump requires a strict seal between the pump body and the pipeline, and a strict seal between the pump casing and the pump shaft. If the seal is not tight, leakage may occur. Or the water seepage and water leakage problems that may occur after long-term use of the fire pump, most of which are caused by the aging and wear of the sealing equipment of the fire pump. A large amount of liquid is leaked, which may affect the delivery capacity of the pump, so how to quickly solve the above-mentioned water leakage problem?
Causes and treatment methods of mechanical seal fire pump leakage:
1. During the installation of the fire pump, the bolts of the pump were loose and leaked
Treatment method: adjust the fire pump to the front position, slowly tighten the screws on the outer ring of the pump one by one, never tighten one screw at a time
2. The sealing surface is uneven, and the liquid in the pump will flow out of the pump along the loosely sealed place
Solution: Provide the model parameters of the vertical multi-stage fire pump to replace the mechanical seal
3. The vibration amplitude of the mechanical seal is severely worn, and water seepage and leakage occur
Solution: Adjust the friction position of the sealing ring, take out the sealing ring, and then replace the position device. If the fastening spring on the sealing ring loses its elasticity or cracks, you can remove the spring and tie it tightly with a steel wire or iron wire of appropriate diameter
4. There are sand holes or cracks in the fire pump body
Solution: replace the fire pump body
Causes and treatment methods of fire water pump packing seal leakage:
1. The pump packing pressure is too tight or too loose to leak water
Treatment method: adjust the tightness of the gland
2. The position of the multi-stage water seal ring is offset and leaks
Solution: Adjust the position of the water seal ring so that the water seal ring is just aligned with the water seal nozzle.
3. The fire pump packing wears too much or the shaft sleeve wears and leaks
Treatment method: replace packing or shaft sleeve
The above are some basic solutions to the problem of water seepage and water leakage during the operation of the fire pump with two sealing methods. When the operator finds a leakage problem during the use of the fire pump, he must repair it symptomatically. What kind of leakage should be done? solve. When the problem is more complicated and cannot be judged by yourself, you can come to Xizhiquan to consult relevant technical personnel.
