Problems solved by technology

In this way, the shear resistance performance of the rubber bearing is tested. The existing problem of this hydraulic compression shear testing machine is that the oil supply circuits for the vertical force loading hydraulic cylinder and the horizontal force loading cylinder are all supplied by quantitative pumps. In the shear test, the system needs to maintain the pressure for a long time, and the quantitative pump is used to supply oil, and the pressure oil is almost all flowed back to the oil tank through the overflow valve under high pressure, the system power loss is large, and the heat is serious
