Analysis And Improvement Of Leaked Failure For Automotive Water Pump

摘要

A model automotive pump was studied, and the leaked failure of automotive water pump was analyzed. Through the statistical data, it was found the failure is mainly due to leakages of thermostat cover. Therefore, the reason of leakages of thermostat cover was analyzed, and improvement scheme was proposed. The scheme was discussed and validated. Finally, the scheme to increase seal gasket of thermostat cover is considered to be the best solution. Product testing and mass production shows that the leakages of thermostat cover don't appear. The leaked failure of automotive water pump is reduced.
