The other end of the inlet tube is connected to extraneous coolant liquid, by the aperture of first blind hole and extraneous coolant inlet
Connection；
Coolant liquid enters from the inlet tube, is entered in the seal chamber by the fluid hole, and stator and entrance are described close
It seals intracavitary coolant liquid and heat exchange occurs；
When the height of coolant liquid is higher than the fluid hole, coolant liquid enters the fluid hole, and by first blind hole and institute
The clearance backflow between inlet tube is stated into extraneous coolant liquid.
