Design and Research on Optimal Structure of Water Seal Cooling of Centrifugal Pump
The water seal of automobile centrifugal pump is an important functional part of the pump,its main failure mode is water leakage,the main reason for water leakage is that the rubber in the water seal melts and fails at high temperature.In view of the difficult problem of water seal leakage due to high temperature,the causes of high temperature failure are analyzed according to the structure and use state of the pump,and the opti-mization structure of two kinds of water seal cooling with grooving and holing of pump body are proposed.The simulation analysis experiment based on Pumplink was carried out,the experimental system was set up,and the two optimized structures of the pump body were compared.The results show that the optimized structure of wa-ter seal cooling with grooving of pump body has better effect on water seal cooling and heat dissipation.
