KCG gear pump burst and oil spills solution to the problem

KCG gear pump burst and oil spills solution to the problem

In the course of the application, KCG gear pump often show the appearance of burst and surface oil spill, which is why? In the face of this situation, probably how useful treatment?

KCG gear pump that can form a large pump burst Analysis of the reasons:

1, Assignment valve in the pilot pressure relief valve or overflow valve stuck, the system is closed in the oil circuit, the system pressure limitless, eventually leading to the big pump burst;

2, the operator did not demand the instructions, private pressure to adjust, the system pressure exceeds the required value is also a simple formation of large pump burst.

Useful plan to deal with big pump burst doubt:

Based on practical experience, the pilot can be a clockwise shift in the pressure regulator, the system pressure may improve 3.0 ~ 4.0MPa; the other hand, the system pressure may drop 3.O ~ 4.0MPa. In addition, both sides of the tank pressure tank should be installed in the gear pump high pressure chamber, to avoid pump "trapped oil", the formation of oil pump burst.

KCG gear pump to form the reasons for oil leakage Analysis:

1, work KCG gear pump internal because of the high pressure for a long time, Park Taibang so that the left and right two pump cover and the pump captive bolt tension by the longer, resulting in loose oil spills;

2, pump cover or pump radial crack, scratch marks, seal damage can also form a spill.

Useful plans to deal with KCG gear pump oil leak questions:

Timing (about 6 months) to see whether the bolts are loose. Sometimes, because the bolt hole depth is shallow, the bolt can not be locked, at this moment, should bolt the corresponding car short.

Wood Pellet Mill

The wood pellet mill is our patent product. It is vertical ring die type. It can make biomass pellets from various materials. Its design is mature and reliable. By Wood Pellet Machine, raw material is feeding vertically and directly in place, with stationary die and moving roller, the material is centrifugal and spread evenly around the die. The independent ejection device ensures the forming rate of pellet, the good design lowers the consumption and enhances the efficiency. It can work 24 hours and lubricate automatically. More than 200 wood pellet lines in and abroad have adopted this machine.
