[Asia Pump Network News] Construction machinery operation or operation, the water pump water leaks are also commonplace. As long as there is no rejection of water ring damage or swelling deformation, inadequate spring seal water pressure or broken and other failures, can carry out emergency treatment. Now let's talk about engine water pump leakage reasons and treatment methods. Engine pump First, the engine water pump causes 1. Installation of the pump, seal seat assembly is not installed in place, causing the pump to continue to leak. As with the hole corresponding to the inspection hole block (rejection) hydrosphere, when the water seal leaks, the cooling water shaft along the water ring will be thrown out from the pump hole and drip, so as to prevent Cooling water flows into the bearing to destroy lubrication. In addition, the replacement of the retaining ring does not pay attention to clear the pump body and the pump cover can not be well combined and sealed, will result in water leakage pump. 2. The old machine, sealing parts wear, corrosion and aging failure, is also the cause of the pump leaks. When the construction machinery is parked for a long period of time, there is no cooling water in the engine, causing the bakelite gasket to deform due to the dry knot and shrinkage. Although the bakelite gaskets will expand but not fully restore the original shape after the water is added, it will cause a small amount of water leakage. In addition, the newly installed pumps, bakelite gaskets and cast iron bushings have not yet fully run well, will also lead to a small amount of water leakage pump. 3. Construction machinery working environment is bad, easily lead to uneven wear bushing seals and bushings end; spring immersed in water for a long time, easy to rust, elastic decline, can also cause water leakage. 4. Forget the release of water in winter or water is not clean, and when the water temperature is too high, the cooling system after the condensation of water vapor freezing, are likely to cause the pump body to be frozen, leading to water leakage. Second, the engine water pump leaking treatment 1. If you find that the engine is running the pump water leakage, shall not immediately stop its work, it should be maintained at the minimum steady speed, while the water inside the cooling system to add water (note: open the water inlet Cover should be put a cover above it to prevent being ejected steam scalding), the engine cooling, short period of time, slow driving, driving to the vicinity of the hidden place and then ruled out. If it is a sudden encounter with the pump casing rupture and leakage, or damage to pump parts and lost pump water role, may be appropriate to replace the relevant parts, troubleshooting. 2. If the pump damage is very serious, there is no repair conditions on the way, the pump can be directly connected to the inlet and outlet to take full advantage of the natural circulation of hot and cold water to temporarily maintain the engine to maintain normal temperature; or use a tube or Bucket as a container, firmly fixed, and then leads two hoses from the container, one connected to the inlet of the engine, the other connected to the engine outlet, the other end of the two pipes are Insert into the container and secure the hose securely. If only the pump casing cracks and leaks, cracks can be handled clean, and then use adhesives to make up. In order to emergency, available egg mixture of cement mixed into a sticky group smear in the cracks, to be solidified a few minutes before you can use. 3. If the water seal due to the seal is not strict there is a slight leakage, but the wear is not too serious, can be spread on a glass plate or a emery cloth, the water seal sealing surface grinding can be smooth; also bakelite water seal Flip before use. However, both should be noted that the water seal and the pump body contact surface should be ground to ensure its sealing performance.
