Pneumatic oil hydraulic pump

Abstract

The invention discloses a pneumatic oil hydraulic pump which comprises a pump body, an actuating assembly, an oil circuit system and a gas path system. The actuating assembly comprises an actuating rod, a main piston and a reset spring; the main piston is fixedly arranged on the actuating rod in a sleeving way; the reset spring is connected with the main piston and is arranged outside the actuating rod in a sleeving way; the oil circuit system comprises an oil chamber; an oil inlet and an oil outlet are connected onto the oil chamber; a first one-way valve is arranged on the oil inlet; a second one-way valve is arranged on the oil outlet; the lower end of the actuating rod stretches into the oil chamber; and the gas path system comprises a piston chamber, a switching shaft cylinder, a gasinlet hole, a switching gas hole and an auxiliary gas outlet hole. The pneumatic oil hydraulic pump provided by the invention is simple and reasonable in structure; and the switching shaft cylinder can smoothly switch a gas path, so that the actuating rod quickly moves in a reciprocating way, the reaction speed is fast, oil supply can be continuously and stably realized, the oil pressure is stable, meanwhile, a good pressurizing effect can be achieved, and ultrahigh hydraulic pressure is provided.

Description

technical field [0001] The invention relates to the field of hydraulic systems, in particular to a pneumatic oil pressure pump. Background technique [0002] Hydraulic transmission uses liquid as the working medium, and uses the pressure energy of the liquid to transmit power. Hydraulic pressure is widely used in industrial and civil industries due to its characteristics of large transmission power, easy transmission and configuration. The function of the actuators (hydraulic cylinder and hydraulic motor) of the hydraulic system is to convert the pressure energy of the liquid into mechanical energy, so as to obtain the required linear reciprocating motion or rotary motion. During the action of the actuators of the hydraulic system, it is necessary to supply oil (into oil) and return oil to the hydraulic actuators, and control the hydraulic actuators through oil pressure. The function of the energy device (oil pressure pump) of the hydraulic system is to convert the mechani...
