Teach you to solve the fire pump Emergency Pump vibration noise problem

The use of diesel engine fire pump will occasionally appear vibration noise phenomenon, which is a headache for many users, but as long as the cause of this problem and the judgment method, and put forward improvement measures, the use of the effect is better. General diesel engine fire pump vibration noise can be summarized as the following problems:

1. Check the grounding bolt of the Pump set. Check whether the grounding bolt of Emergency Pump is loose or the foundation for installing the Pump set is faulty.

Corresponding measures: tighten the anchor bolts and reinforce the foundation.

2. Check the tachometer and Emergency Pump to check whether the turbine speed of the Pump group exceeds the rated speed of the Pump.

Emergency Pump Adjust the speed regulating system to make the Pump work at the rated speed.

3. Check the noise to see whether there is a gap in the suction tube dehydration, resulting in a large number of gas inhalation. Check items to see whether there is vortex at the inlet, whether the depth of the flood is too shallow, etc.

Corresponding measures: adjust the height between the suction inlet and the liquid level.

4. Check whether flow erosion occurs in the Pump. If the flow is too large, the suction resistance of Emergency Pump increases or the liquid operating temperature rises, which may cause the Pump flow erosion, resulting in vibration and noise.

Corresponding measures: adjust the flow rate and liquid operating temperature.

5. Check the impeller to see if it is damaged or foreign matter is inhaled.

Corresponding measures: replace the damaged parts and adjust the neutralization clearance of the coupling to be not too large.

If the diesel engine fire pump again this fault, we can try to use the above methods to solve, if not to immediately find maintenance personnel to repair. Although we can’t put an end to the occurrence of these failures, but we can reduce the occurrence of problem, as long as before using the product completes the installation work, in use process can timely find problems and summing up experience and method, can avoid similar problems appear again, but is good for processing and avoid the occurrence of common failures, still can make the product can be fully utilized, Make the effect more obvious.
