Abstract

The high-sealing booster pump comprises a motor and a pump body part, and the pump body part comprises a front pump body, a pressure plate assembly, a rear pump body, a diaphragm assembly, a diaphragm seat and an eccentric sleeve; the diaphragm assembly comprises a diaphragm piece and a piston push block; the diaphragm piece and the piston push block are fixed together through a bolt; a sealing assembly is arranged between the bolt and the piston push block; the sealing assembly comprises a gasket, an extrusion piece and an elastic piece. The gasket is arranged on the bolt in a sleeving manner; an extrusion notch is formed in the gasket; the extrusion part extrudes the extrusion notch to drive the elastic part to extend in the radial direction; and the elastic piece is in a contraction state and continuously applies extrusion force to the extrusion piece. According to the high-sealing booster pump with the sealing assembly, through the arrangement of the sealing assembly, sealing failure, caused by abrasion, at the bolt connecting position is avoided, the diaphragm piece and the piston push block are in a sealed state all the time, and the boosting effect of the booster pump is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of membrane booster pumps, in particular to a high-sealing booster pump with sealing components. Background technique

[0002] The existing booster pump often has the problem of motor damage caused by internal leakage of the booster pump. On the one hand, the overall sealing effect of the booster pump is poor; In the case of extrusion caused by changes in the internal pressure of the booster pump for a long time, the internal parts of the booster pump cannot be connected to each other, resulting in leakage problems.

[0003] The existing diaphragm and piston push block are generally connected by bolts, and the gasket is easy to wear, and the sealing performance is greatly reduced after wear, which seriously leads to the failure of supercharging and the damage of the motor. Based on this, how to design a high-sealing booster pump with sealing components is the technical problem to be solved by the present in...

Examples

Embodiment 1

[0022] Embodiment 1, referring to the accompanying drawings, a high-sealing booster pump with a sealing assembly, including a motor 1 and a pump body part, the pump body part includes a front pump body 2, a pressure plate assembly 3, a rear pump body 4, and a diaphragm assembly 5 , a diaphragm seat 6 and an eccentric sleeve 7; the diaphragm assembly 5 includes a diaphragm 51 and a piston push block 52; the diaphragm 51 and the piston push block 52 are fixed together by bolts 53;

[0023] A sealing assembly 54 is arranged between the bolt 53 and the piston push block 52; the sealing assembly 54 includes a gasket 541, an extrusion part 542 and an elastic part 543; the gasket 541 is sleeved on the bolt 53; the The gasket 541 is provided with a squeezing gap 5411; the squeezing member 542 squeezes the squeezing gap 5411 to drive the elastic member 543 to radially expand; the elastic member 543 is in a contracted state, and continuously squeezes the squeezing member 542. pressure; ...
