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.
