Water pump leakage cause
(1) When the water pump is installed, the water seal seat ring assembly is not installed in place, causing the water pump to continue to leak water. Because the pump shaft corresponding to the inspection hole has a water blocking (flicking) ring, when the water seal leaks, the cooling water will be thrown out and dripping out of the pump's viewing hole when it encounters the water blocking ring along the pump shaft. Cooling water flows into the bearings to damage lubrication. In addition, when replacing the water retaining ring, care is not taken to clear that the pump body and the pump cover cannot be well combined and sealed, which will also cause the pump to leak water.
(2) The working environment of construction machinery is bad, which is likely to cause uneven wear of the bakelite gasket and the end face of the bushing; the spring is immersed in water for a long time, it is easy to rust, the elasticity is reduced, and it can cause water leakage.
(3) In winter, if you forget to release water or the water is not clean, and the temperature is too high during the discharge, the freezing of water vapor in the cooling system may cause the pump body to be frozen and cracked, resulting in water leakage.
(4) The machine is old, and the wear, rust and aging of the parts inside the water seal are also the reasons for the water leakage of the pump. When the construction machinery is parked for a long time, because of the lack of cooling water in the engine, the mixed-flow pump manufacturers cause the bakelite seals to deform due to dryness and shrinkage. After adding water, the bakelite seals will swell but will not fully return to their original state, which will cause a small amount of water leakage. In addition, for newly installed water pumps, the bakelite seals and cast iron bushes have not completely run in, which will also cause a small amount of water leakage in the water pumps.
If you find that the water pump of the engine is leaking, do not stop it immediately. Keep it at a low stable speed, and at the same time add water to the inside of the cooling system. Cover to prevent scalding from the water vapor), cool down the engine, drive for a short time and at a slow speed, and drive to a nearby hidden place before removing it. If the pump casing is suddenly broken and leaks water, or the internal parts of the pump are damaged and the pumping effect is lost, the relevant parts can be replaced as appropriate to eliminate the fault.
