Oil cylinder piston used for air extraction unit of trailer pump, and with high strength and sealing performance

Abstract

The invention relates to the technical field of oil cylinder pistons, and specifically relates to an oil cylinder piston used for an air extraction unit of a trailer pump, and with high strength and sealing performance. The oil cylinder piston used for the air extraction unit of the trailer pump, and with high strength and sealing performance comprises a shell body, wherein oil inlet ports are connected to the two ends of the shell body separately, one end of each oil inlet port extends into the shell body, and a clamping mechanism is installed at the other end of each oil inlet port in a sleeved manner; exhaust mechanisms are connected to the two ends of the shell body separately, and one end of each exhaust mechanism extends into the shell body; and a sealing block is connected to one side of the shell body. According to the oil cylinder piston used for the air extraction unit of the trailer pump, and with high strength and sealing performance, first sealing rings are arranged, a plurality of groups of the first sealing rings are installed on each pressing block, and then the sealing performance among the pressing blocks is effectively improved; and therefore, the occurrence of the case that during reciprocating running of a movable rod, oil in the shell body is leaked out from gaps in the pressing blocks, and then a pressure in the shell body is insufficient during the running of the movable rod, so that the running efficiency of the device is reduced, or the device cannot be used, is prevented.

Description

technical field [0001] The invention relates to the technical field of oil cylinder pistons, in particular to an oil cylinder piston with high strength and good sealing performance for an air pumping unit of a drag pump. Background technique [0002] The cylinder piston is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating or oscillating motion. It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is stable, so it is widely used in various mechanical hydraulic systems, so the cylinder piston is used as the actuator during the operation of the drag pump pumping unit . [0003] Many existing oil cylinder pistons are poorly sealed, which will lead to hydraulic oil leakage, which will increase the consumption of hydraulic oil by the oil cylinder piston, and will also affect the worki...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a cylinder piston with high strength and good sealing performance for the air pumping unit of the drag pump, so as to solve the problem of poor sealing performance of many existing cylinder pistons in the above-mentioned background technology, which will cause hydraulic oil leakage. As a result, the consumption of hydraulic oil by the cylinder piston increases, and it also affects the working efficiency of the cylinder piston.
