As the production technology and market demand, production water supply demand is gradually increasing, need to increase the original water.
The original water pump of the columns as in the existing (

。
On the scene after turning without jamming phenomenon, after checking process found in the original water water pump outlet pressure and water pump, after the examination revealed: 1.
From the point of the cylindrical section, all is the old fault trace.
The section for the new and old part 2.
2.
Can be seen from the impeller blade cavitation phenomenon exists.
Bearings, machine is not found damage phenomenon.
3.
Coupling bolts, the impeller back caps connecting bolts are loose.
4.
The entrance no foreign body was found.
DCS data to be obtained, A raw water pump overload and other anomalies.
Cause analysis: 1, the material existence of stress concentration, long run lead to crack of axle shaft fracture cause;
2, shaft heat treatment is not good, no modulation processing.
There are some internal defects in 3, the material itself.
4, cause impeller cavitation erosion leads to failure of dynamic balance, causing fatigue fracture spindle weak positions.
Treatment recommendations: testing analysis of spindle material etc.
