Description

Oil pressure part pressure maintenance ability detects frock Technical Field The utility model relates to the technical field of oil pressure component detection devices, in particular to an oil pressure component pressure maintaining capacity detection tool. Background Current stamping line oil pressure systems use a large number of hydraulic drive components powered by hydraulic oil, such as hydraulic cylinders, hydraulic pumps, hydraulic clamps, and the like. The internal sealing performance of the hydraulic component is high in requirement, and the sealing performance is reduced due to the reasons of sealing aging, sealing damage caused by oil impurity abrasion and the like after long-time use, so that the function of the component is invalid. In order to ensure normal performance of the oil pressure component, the current stamping production line mainly adopts measures to periodically and old update hydraulic components such as an oil cylinder, an oil pump and the like or replace an internal sealing element, and the replacement of the sealing element becomes an effective mode for reducing replacement cost of spare parts because most of failure modes of the oil pressure component are component function abnormality caused by damage of the internal sealing element. However, for the effectiveness detection after the replacement of the internal seal of the hydraulic component, no effective offline detection method exists in all production lines at present, and the detection is needed after the component is assembled back.
