Abstract

The invention discloses a hydraulic system for an oil cylinder pressure maintaining test. The hydraulic system comprises an oil supply system, an overflow system, a first oil return system and secondoil return system and is characterized in that the oil supply system comprises an oil pump, a reversing valve, a throttling valve, a pressure regulating valve and a first stop valve which are sequentially communicated through an oil inlet pipe, the oil inlet end of the oil inlet pipe extends into an oil storage tank, and the oil outlet end of the oil inlet pipe is provided with a first pipe connector; the overflow system comprises an overflow pipe and an overflow valve arranged on the overflow pipe, and the oil inlet end of the overflow pipe is communicated to the oil inlet pipe between the oil pump and the reversing valve; the first oil return system comprises a first oil return pipe, a second stop valve and a filter, the second stop valve and the filter are communicated through the firstoil return pipe, and the oil inlet end of the first oil return pipe is communicated to the oil inlet pipe between the first stop valve and the pressure regulating valve; the second oil return systemcomprises a second oil return pipe, and the oil inlet end of the second oil return pipe is provided with a second pipe connector. The hydraulic system can supply oil for an oil cylinder so as to drivethe oil cylinder to telescope.

Description

technical field [0001] The invention relates to oil cylinder testing equipment, in particular to a hydraulic system for oil cylinder pressure maintaining test. Background technique [0002] At present, for the assembly and production of oil cylinders, in order to avoid oil leakage after the oil cylinders leave the factory, after the oil cylinders are assembled, it is necessary to carry out a corresponding pressure maintenance test on the oil cylinders to detect whether oil leakage occurs during the working process of the oil cylinders. Then judge the sealing effect of the oil cylinder to avoid quality problems of the oil cylinder after leaving the factory. In order to complete the pressure-holding test of the oil cylinder, the applicant designed a corresponding pressure-holding test device. The pressure-holding test device is mainly composed of a mechanical part and a hydraulic part. The oil cylinder delivers hydraulic oil to drive the telescoping action of the oil cylinder...
