Description

Technical Field

[0001] The utility model relates to the technical field of plunger sleeves, in particular to a plunger sleeve for facilitating sleeve connection of an anti-stuck oil outlet valve. Background Art

[0002] The traditional plunger pump is mainly used in various automobile internal engines to provide airflow assistance and propulsion when gasoline is burned. The plunger pump is an important device in the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure.

[0003] Plunger pumps have the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. Plunger pumps are widely used in situations where high pressure, large flow and flow regulation are required, such as hydraulic presses, passenger car machinery and ships.

Currently, under the assembly pressure of the plunger sleeve and after a long period of use, the plunger often becomes stuck, resulting in a short service life. In addition, there is no good protective device, which means that the device will be directly damaged in the event of a collision. Utility Model Content
