Embodiment Construction

[0012] Adopt specific embodiment below in conjunction with accompanying drawing to describe the present invention in detail:

[0013] like figure 1 The life-extending oil pump shown includes a plunger 2 and a plunger sleeve 1, the plunger 2 is arranged in the plunger sleeve 1 in a sealed and sliding manner, and a slide groove is provided on the end of the plunger 2 protruding from the plunger sleeve 1 21. The opening of the plunger sleeve 1 is provided with a protrusion 13 matching the chute 21 , and the chute 21 is arranged in a spiral manner along the axial direction of the plunger 2 .

[0014] figure 1 The shown oil inlet 11 and oil outlet 12 are both arranged on the top of the plunger sleeve 1, and the oil inlet 11 can be arranged on the side wall of the plunger sleeve 1, so that during the reciprocating movement of the plunger 2, the plunger The plug 2 can close or open the oil inlet 11 . Corresponding to the oil inlet 11 on the side wall, a channel can be set in the...

Abstract

The invention discloses a life-extending oil pump, which comprises a plunger and a plunger sleeve. The plunger is arranged in the plunger sleeve so as to seal and slide. There is a protrusion matching the chute on the top, and the chute is arranged spirally along the axial direction of the plunger. The life-extending oil pump of the present invention is provided with a spiral chute on the plunger, and a protrusion corresponding to the chute is provided at the opening of the plunger sleeve. Rotating in the opposite direction, the friction of the plunger in the plunger sleeve is not like the existing plunger, which only has axial friction, and the friction is divided into two parts, axial and circumferential, so that the wear efficiency of the plunger is reduced, and its service life is relatively extended .

Description

technical field [0001] The invention is a life extension oil pump. Background technique [0002] The oil pump is a machine that transports oil or pressurizes oil. It is generally a piston structure, that is, it includes a plunger and a plunger sleeve. Going down against the plunger; during the up and down process of the plunger, the corresponding inlet and outlet are opened to realize the function of oil delivery. Since such an oil pump needs the action of the elastic member, its elasticity will be affected after a long service time, resulting in a short service life and a complex structure. Contents of the invention [0003] The purpose of the present invention is to provide a life-extending oil pump to solve the problem of short service life of the existing oil pumps. [0004] The purpose of the present invention is achieved through the following technical solutions: a life-extending oil pump, including a plunger and a plunger sleeve, the plunger is sealed and slidably...
