The Failure Analysis And Maintenance For Hydraulic Axial Piston Pump

Hydraulic driving technology has already become one of the main driving technology for its special virtue. The hydraulic pump is the drive component of the hydraulic system . The failure of the hydraulic pump on construction machinery will seriously affect the usage . So the research of failure analysis of hydraulic pump and the research of maintenance of hydraulic system is very important to our corporation, it is also wanted by the other many big building corporations.The thesis consists two parts: failure analysis of hydraulic axial piston pump and maintenance of hydraulic system. The first emphasis of the thesis is the failure analysis of hydraulic axial piston pump, the second is the example about the high temperature analysis of the K3V112DT type double pump.Combining with these problems , the thesis introduced the failure analysis methods of hydraulic system , the failure classification of hydraulic system and the quality of the failure . It drew the failure analysis flow sheet of hydraulic axial pump , calculated temperature increase of hydraulic system , and finished the test of hydraulic axial piston double pump .At last .through the discussion about daily maintenance & management methods and repair of hydraulic axial piston pump , it introduced the management system & contents for our corporation . I hope that can have effect on improving the level of our machine management .
