Mixing plant water additive system common breakdown and solution

Symptoms:

Pump does not start properly, pump no water or insufficient flow, vibration and noise.

Analysis:

Could be the cooling fan motor rotation is not flexible, reverse motor or suction pipe inlet.

Treatment methods:

1, in the case of power off, toggle whether motor cooling fan by hand the flexibility, if fixed, could be rotor is jammed, remove foreign bodies after lubricating grease.

2, if you are pumping water, may be the motor turned upside down, at which point should be immediately shut down, should be reversed any two phases in three-phase power supply, pump rotation direction can be changed.

3, the water turned normal after the centrifugal pump turns but no water coming out, possible causes are

1) suction clogged with debris, should be cleared after filtering devices;

2) suction pipe leak or instrument may be the weld leak, pipes with sand holes or cracks, joints caused by poor gasket seal.

4, abnormal voice or vibration is too large, it may be

1) impeller equilibrium are not aligned, should be immediately corrected;

2)concrete pump and motor shaft misalignment should be corrected; pump inhalation of foreign bodies, blocked or damaged impeller, shutdowns.
