In the engine block of a car, there are several watercourses for circulating cooling water, which are connected to the radiator (commonly known as a water tank) on the front of the car to form a large water circulation system. Use process, the car pump failure or damage, how to deal with it? Let Xiaobian tell you! Car engine pump Car engine pump common failures and treatment methods 1. Check the pump body and pulley wear and damage, if necessary, should be replaced. Check the pump shaft bending, journal wear, shaft thread damage. Check the blade on the impeller broken, shaft hole wear is serious. Check the water seal and bakelite gasket wear, such as more than the use limit should be replaced with new pieces. Check the bearing wear, available table measurement bearing clearance, such as more than 0.10mm, you should replace the new bearing. 2. Pump removed, can be decomposed in order. Parts should be decomposed after cleaning, and then one by one check to see if there are cracks, damage and wear and other defects, if serious defects should be replaced. 3 water seal and seat repair: water seal, such as wear from the groove, available emery cloth, such as wear should be replaced; water seal if any rough scratches, flat reamers or lathe repair. In the overhaul should be replaced when the new water seal components. 4. In the pump body with the following damage allow welding repair: the length of less than 3Omm, does not extend into the bearing hole cracks; flange with the cylinder cover has broken parts; oil seal seat hole damage. The pump shaft bending shall not exceed 0.05mm, otherwise it should be replaced. Impeller blade damage should be replaced. Pump shaft aperture wear serious should be replaced or set repair 5. Check the pump bearing rotation is flexible or abnormal sound, if there is a bearing problem, should be replaced. 6. Pump assembled, hand rotation, the pump shaft should be free of stagnation, impeller and pump housing should not rub rub. Then check the pump displacement, if there is a problem, you should check the reasons and remove. If the pump fails, the coolant will not reach the appropriate place, its performance will not be effectively played, and ultimately affect the work of the engine. Therefore, we must strengthen the inspection of the pump.
