Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0026] The pump in the present invention, especially a submersible pump, adopts a double-walled oil outlet shell structure to reduce noise.

[0027] Such as figure 1 As shown, the pump in the present invention includes a housing, a driving part and a fluid pumping part. Wherein, a supporting partition is provided inside the housing, thereby dividing the inside of the housing into a first cavity 1 and a second cavity 2, the driving part is installed in the first cavity 1, and the fluid pumping part is installed in In the mounting cavity of the support partition.

[0028] A through hole 23 is provided on the support partition, so that one end of the driving part can be connected with the fluid pumping part after passing through the through hole 23, ...

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.

Description

technical field [0001] The invention relates to the technical field of fluid delivery, in particular to a pump. Background technique [0002] Gear pump is a commonly used hydraulic pump in hydraulic transmission system. According to the gear meshing form, it can be divided into two types: internal gear pump and external gear pump. Compared with the involute external gear pump, the cycloid internal gear pump has the advantages of compact structure, light weight and small size. However, the internal meshing gear pump in the prior art has the problems of high noise and poor heat dissipation. Contents of the invention [0003] The invention provides a pump to solve the problems of high noise and poor heat dissipation of the pump in the prior art. [0004] In order to solve the above problems, as an aspect of the present invention, a pump is provided, including a housing, a driving part and a fluid pumping part, a supporting partition is provided inside the housing, and the s...
