Abstract
The invention provides a pump. The pump comprises a shell, a driving part and a fluid pumping part. A supporting separation part is arranged in the shell and divides the interior of the shell into a first cavity and a second cavity. An annular groove communicating with the second cavity is formed between the supporting separation part and the inner wall of the shell. The fluid pumping part is mounted in a mounting cavity of the supporting separation part. One end of the driving part penetrates through a through hole in the supporting separation part and then is connected with the fluid pumping part. The fluid pumping part presses fluid in the first cavity into the second cavity and pumps the fluid out of the second cavity. According to the pump, noise generated by the fluid pumping part in the rotating process is effectively absorbed and lowered through fluid filled up in the annular groove, and heat of the shell and the supporting separation part can be taken away. Overall heat dissipation of the shell is facilitated. Flow pulsation is small. The motor efficiency is high. The pump has the characteristics of being compact in structure, low in cost and noise and good in heat dissipation.
