After the external submersible pump absorbs liquid, the shielded submersible pump is discharged directly from the outlet of the pressurized water chamber by the action of the impeller. The structure design is simple and the efficiency is relatively high. Figure 10-2 shows the typical external submersible pump. . In order to improve the cooling condition of the external submersible pump, the motor casing of the submersible pump with high power is often made into a jacket type, and the liquid in the high pressure zone of the pump water is introduced into the jacket cooling motor.
