Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0022] Such as figure 1 As shown, a plunger component 500 of a high-pressure plunger hydraulic pump includes a plunger body 100 and a slide shoe 200 connected to the front end of the plunger body 100, and the bottom end of the slide shoe 200 is provided with a rounded corner with a radius of 1 mm. The front end of the plunger body 100 is provided with a ball head 210 for wrapping the sliding shoe 200, and the plunger body 100 is provided with a cavity for hydraulic oil flow. Such as figure 2 As shown, the plunger body 100 behind the ball head 210 is provided with a through hole 211 communicating with the cavity, and a check valve 300 for ensuring the one-way flow of hydraulic oil is provided in the cavity. When the hydraulic pump is wo...

Abstract

The invention discloses a plunger part of a high pressure plunger type hydraulic pump. The plunger part of the high pressure plunger type hydraulic pump comprises a plunger body and a sliding shoe connected with the front end of the plunger body; the front end of the plunger body is provided with a ball head used for being wrapped by the sliding shoe; a hole cavity for hydraulic oil flowing is formed in the plunger body; a through hole communicated with the hole cavity is formed in the portion, behind the ball head, of the plunger body; a check valve used for guaranteeing one-way flowing of hydraulic oil is arranged in the hole cavity; and when the hydraulic pump works, the plunger part is pushed to reciprocate, and the hydraulic oil is pushed by the plunger part to achieve one-way flowingthrough the hole cavity in the plunger body. The structural change is large, the plunger part is matched with the existing high pressure plunger type hydraulic pump, the pulling and disengaging forceof the plunger body and the sliding shoe is very small, the acting force of a reset spring is located on the plunger body, and therefore the closing requirement of the plunger part is greatly lowered; and meanwhile, the sliding shoe in the scheme is free of sliding friction, a plunger pair is free of complicated stress, the work stability is improved, and the service life of the plunger part is greatly prolonged.

Description

technical field [0001] The invention relates to the hydraulic field, in particular to a plunger component of a high-pressure plunger hydraulic pump. Background technique [0002] The development of the hydraulic field is very rapid, and high pressure and high speed are the development trend. In the hydraulic system, the power source can provide high pressure hydraulic pump is the key to the development of the whole system. The existing high-pressure plunger pump mechanisms are different, and the existing plunger parts cannot be matched with them, and the existing plunger parts have large friction force, poor high-pressure effect and short service life. [0003] Therefore, the prior art still needs further improvement and development. Contents of the invention [0004] The purpose of the present invention is to provide a plunger part of a high-pressure plunger hydraulic pump, aiming to solve the problems that the existing plunger part cannot match the existing high-pressu...
