The cause of the KCB gear oil pump that may cause the large pump to burst: 1. The pilot pressure regulating valve or the overflow valve in the working distribution valve is stuck, the system oil circuit is in a closed state, the system pressure is infinitely increased, and finally the large pump bursts. 2, the operator did not follow the instructions, arbitrarily adjust the pressure, so that the system pressure exceeds the specified value is also likely to cause large pumps to burst. KCB gear oil pump is often prone to bursting and oil leakage during use, which may cause KCB gear pump, ie large pump explosion, to analyze:
1. The pilot pressure regulating valve or the overflow valve in the working distribution valve is stuck, the system oil circuit is in a closed state, the system pressure is infinitely increased, and finally the large pump bursts;
2. The operator does not adjust the pressure without authorization according to the instructions. If the system pressure exceeds the specified value, it will easily cause the large pump to burst.
An effective solution to solve the problem of large pump explosion:
According to practical experience, Botaibang can turn the pilot pressure regulating bolt clockwise for one week, and the system pressure can be increased by about 3.0~4.0MPa. Conversely, the system pressure can be reduced by about 3.O~4.0MPa. In addition, the pressure-reducing grooves of the two side plates should be installed in the high-pressure chamber of the gear oil pump to prevent the oil pump from generating "trapped oil" and causing the oil pump to burst.
Analysis of the causes of oil leakage in the KCB gear pump:
1. Working inside the KCB gear oil pump, due to the long-term high pressure, the connecting bolts of the left and right pump caps and the pump body are lengthened by the tension, causing loose oil leakage;
2, the pump cover or pump body has radial cracks, scratches, oil seal damage, etc. will also cause oil leakage.
An effective solution to solve the oil leakage problem of KCB gear oil pump:
Check the bolts for looseness on a regular basis (about 6 months). Sometimes, because the depth of the bolt hole is shallow, the bolt cannot be locked. At this time, the bolt should be short.
