Abstract

The invention relates to a jacking cylinder control hydraulic system. The hydraulic system comprises a power control valve block, a jacking cylinder control valve block, a foundation device and a jacking cylinder; the foundation device, the power control valve block, the jacking cylinder control valve block and the jacking cylinder are serially connected in sequence; a pressure gauge is arranged in the connecting place between the jacking cylinder and a y oil port of an insertion piece g for continuously monitoring the port pressure of the whole jacking cylinder to control the pressure stability of the jacking cylinder; an air filter is arranged on an oil tank of the foundation device for reducing the probability of feeding dust or impurities in air into the oil tank to prevent the conditions of pipe blockage and unstable pressure caused by a lot of dust entering the oil tank; and through simple connection between control valves and pipes, the pressure control of the jacking cylinder is realized, the uniform pressure distribution can be continuously and stably provided, and the pressure testing data is more precise.

Description

technical field [0001] The invention relates to a hydraulic control system, in particular to a jack cylinder control hydraulic system. Background technique [0002] In the pressure testing machine, the control of the jacking cylinder generally needs to precisely control the stroke of the jacking cylinder to realize the control of the pressure. Generally, when controlling the jacking cylinder, it is necessary to control the complex oil circuit, the return stroke and the downstroke of the jacking cylinder The lack of connection between the electromagnetic controls leads to unstable return, downward and pressure-holding effects of the oil cylinder, resulting in unstable pressure tests, resulting in unsatisfactory pressure test results and inaccurate data. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a jacking cylinder control hydraulic system, which can solve the problem of inaccurate pressure test data due to in...
