What are the reasons for water pump leakage in Haval H6?
1 Answers
Haval H6 water pump leakage reasons are as follows: Excessive axial movement of the water pump rotor: The interference between the auxiliary seal and the shaft is too large, preventing the dynamic ring from moving flexibly on the shaft. After the pump's dynamic and static rings wear out, the lack of compensatory displacement leads to leakage. Insufficient lubrication on the sealing surface: Causes dry friction or scratches on the sealing end face, resulting in water pump leakage. Periodic vibration of the rotor: Misalignment between the stator and the upper/lower end covers, or imbalance between the impeller and the main shaft, cavitation, or bearing damage (wear). These conditions shorten the seal's lifespan and cause leakage.
