This research is devoted to the reliability evaluation of axial piston pump, through the design of power recovery test loop, to achieve the effective reduction of energy consumption and cost, while ensuring the accuracy of the test. By collecting the key performance parameters of the pump such as flow, pressure and temperature, and using Weibull distributed parameter estimation method for in-depth data analysis, this paper aims to quantify the reliability of the axial piston pump and predict its failure rate. It is found that the optimized design of the test circuit can effectively simulate the running state of the pump under the actual working conditions, and the Weibull distribution method shows high accuracy in the reliability prediction of the pump. The paper also discusses the two non-common failure modes of axial piston pump: seal failure and control system failure, and puts forward the corresponding preventive measures and improvement schemes. The research results are of great value for improving the reliability of the design and operation of the axial piston pump, and provide an important reference for the design and maintenance of the hydraulic system, which is conducive to the further development and application of hydraulic technology.
