Abstract The design processes of pump hydraulic fixer from several aspects are presented,such as the design of system structure,the analysis of clamp′s strength,the design of hydraulic system and the principle of electric control.To ensure no leak phenomenon,the technique of groove and seal is applied in pipe connective part.The results show that hydraulic fixer strength is about 88.238 kN and the least working pressure is about 17.563 MPa under the pressure of 6.4 MPa in hydraulic cylinder.Compared with traditional flange alignment,the test results show that the fixer has no leak phenomenon,hydraulic loss on alignment part has declined about 0.156%,and the number of pump tested in the same time is 1.5 times than before,so it can greatly improve efficiency of pumps′ testing.
