Leakage of gear oil pumps is the most common and most problematic.Many technicians may have their own methods for dealing with this accident, but there are still many people who do not know how to solve it and cannot fundamentally solve the problem. First of all, they must understand what caused the large-flow gear pump oil pump running leak. 1. The oil quality is not clean and the oil return is not smooth. 2. The gland of the large-flow gear pump is not installed correctly, and the oil drain holes on the front cover and the rear cover are leaked. 3. The outer diameter of the seal ring fits too loosely with the diameter of the seal seat. 4. The direction of the pump body of the large-flow gear pump is reversed, so that the oil pressure port is connected to the unloading ditch, and a pressure is formed to punch the seal ring out. 5. Seal selection and installation are not tight.The selection of the seal is very important, and it must be installed well. Some parts must be closely coordinated. If a leak occurs, first check whether the seal selection and installation are correct, and then check whether the working conditions are stable. Only by understanding the cause of the leakage of the large flow gear pump can we better solve the problem.Here are just a few points. In fact, there are many problems about large flow gear pump oil pump leakage. If you need to know more, please consult.
