Abstract

The invention relates to the technical field of automobile engine cooling water pumps, in particular to an energy-saving automobile engine cooling water pump. The energy-saving automobile engine cooling water pump comprises a pump case, and the pump case is provided with a bearing seat, a water seal seat, a spiral flow channel, a water leakage hole, an installation hole and a sealing groove; and a shaft connection bearing is installed on the bearing seat of the pump case, a transmission flange plate is installed on a journal at the left end of the shaft connection bearing, a water seal is installed in the middle of a journal at the right end of the shaft connection bearing and on the water seal seat of the pump case, a screw hole is formed in the end face of the journal at the right end of the shaft connection bearing, an impeller is installed on the journal at the right end, and blades of the impeller are located on one side of a water inlet of the impeller. According to the energy-saving automobile engine cooling water pump, the problems that existing automobile engine cooling water pumps are high in noise, low in work efficiency and large in power loss are solved.

Description

technical field [0001] The invention relates to the technical field of automobile engine cooling water pumps, in particular to an energy-saving automobile engine cooling water pump. Background technique [0002] In the prior art, there are mainly two ways of water intake to the automobile engine cooling water pump: one is that the water inlet pipe is provided on the side of the pump body, and the water enters the annular water suction chamber from the side, and then enters the impeller. The other is that the water enters the impeller directly from the body. At this time, the water seal is set in the high pressure area on the other side of the impeller water inlet. At present, the cooling water pumps of automobile engines, especially the engine cooling water pumps of passenger cars, are mostly used. One method, and most of the impellers are open impellers that are stamped and processed by steel plates; the problems in the prior art automotive engine cooling water pumps are: 1...
