Most of the fire fighting water sources provide fire fighting water, all need fire pumps for pressurization to meet the requirements of water pressure and water quantity when fighting fire, which is an important part of fire fighting. In daily use, we often encounter fire pumps produce vibration or make strange noises, where exactly is the problem? And how should we solve?
1. Not firmly installed, loose fasteners
After the centrifugal fire pump starts, the impeller will rotate at high speed. Centrifugal fire pump is not firmly installed, or a long time to run the fasteners loose, will make the pump in the process of vibration, noise, and even in a short time was damaged.
2. Wear between the impeller and sealing ring
Impeller and seal ring such as can not ensure a good lubrication state, the wear between the two to increase the gap, when the gap exceeds a certain value will lead to pump vibration, noise. The degree of wear increases with the prolonged operation time of the pump.
3. Pump body and pump shaft installation is not correct
The effective energy obtained by the liquid through the fire pump is obtained from the impeller of the pump, and the energy obtained by the impeller is obtained from the pump shaft, and the energy obtained by the pump shaft is provided by the motor. When the pump is running, the pump shaft drives the impeller to rotate at high speed. If the pump body and pump shaft are not installed correctly, it will lead to the impeller deviating from the pump casing friction, thus generating vibration, which will seriously lead to the impeller and pump casing damage.
4. Cavitation phenomenon leads to abnormal sound inside the pump
Suction line resistance is too large, poor sealing leakage into the air, the temperature of the pumped liquid is too high, the flow rate is too large, etc., will trigger the cavitation phenomenon, so that the pump produces abnormal sound or violent vibration.
If your fire pump in the use of the process of vibration and noise, you can refer to the above points one by one, it is easy to find out the problem and can be solved.
