Abstract

The invention discloses a four-column hydraulic machine return pipeline hydraulic oil filter, which comprises a filter cylinder with a large opening at one end and a small opening at the other end. The filter cylinder is provided with a filter element, and a plurality of one-way conduits are arranged in the filter element. A sealing ring is provided at the large opening end of the filter cylinder, and a sealing ring is provided between the sealing ring and the filter element. The small opening end of the filter cylinder is connected to an inner spiral tube. The internal pipeline of the inner spiral tube is spiral, and the end of the inner spiral tube is connected to a pipe. The joint is provided with a connecting thread on the pipe joint. The filter cylinder of the hydraulic oil filter of the return pipeline of the four-column hydraulic machine of the present invention has a large structure at one end and a small structure at the other. Connecting the return pipeline can effectively buffer the oil pressure. The oil pressure is balanced, thereby effectively improving the circulation stability of the hydraulic oil in the return pipeline.

Description

technical field [0001] The invention relates to a filter, more precisely, a hydraulic oil filter of a return pipeline of a four-column hydraulic press. Background technique [0002] The four-column hydraulic press is a kind of special hydraulic oil as the working medium, and the hydraulic pump as the power source. The force of the pump makes the hydraulic oil enter the cylinder / piston through the hydraulic pipeline, and then there are several sets of seals in the cylinder / piston that cooperate with each other. For parts, the seals in different positions are different, but they all play a role in sealing, so that the hydraulic oil cannot leak. Convert oil pressure energy into mechanical energy Oil hydraulic transmission is a transmission method that uses liquid pressure to transmit power and control. The hydraulic device is composed of hydraulic pump, hydraulic cylinder, hydraulic control valve and hydraulic auxiliary components. The four-column hydraulic press will insta...
