Single stage pumps have some little issues when operating. We must pay attention to this kind of glitch, otherwise it will greatly shorten the service life of the pump. So what are the reasons for our common problems?
A. Increased vibration
Rotor imbalance
2. Bearing wear
3. The shelf parts are loose
4. The pump shaft is not aligned with the prime mover shaft.
B. Low flow rate and range
1. The pump body or the suction pipe has gas
2. Pipe blockage
3. The direction of rotation is wrong
C. The temperature is too high
1. Rotating part is unbalanced
2. Bearing wear
3. Bearing cooling effect is worse
4. Bearing installation error
D. Sealing severe leaks
1. Loose filler
2. Mechanical seal damage
3. Improper sealing fluid pressure
4. The pump shaft is not aligned with the prime mover shaft.
These glitch are extremely common in our use of single-stage centrifugal pumps, and the elimination of these glitch is important for maintenance pumps.
