Cylinder external measurement hydraulic testing machine

    Principle   

    The cylinder external measurement hydrostatic tester is mainly used to conduct pressure test on the tested cylinder and obtain the volume residual deformation rate of the tested cylinder, which is controlled by computer. Its working principle is as follows: put the test bottle in a special water jacket, use a high-pressure pump to pressurize the test bottle, and automatically enter the pressure maintaining state after reaching the set pressure, and conduct a pressure test on the test bottle. At the same time, the cylinder expands under the test pressure, squeezing part of the water in the water jacket into the measuring cup. This part of the water is the volume deformation of the test bottle, which is transmitted to the industrial computer through the water collection system, After the cylinder is depressurized, the elastic deformation disappears, so the water in the measuring cup returns to the water jacket. The unreturned water volume is the volume residual deformation of the tested cylinder, which is transmitted to the industrial computer through the water volume collection system. The ratio of the volume residual deformation to the total deformation is the volume residual deformation rate of the cylinder.
