As long as the inner wall surface with sand paper slip and check eddy leaves [or gear] whether there are cracks, any necessary replacement parts. Secondly also check whether the shaft deformation [curl]. If necessary the lathe. Feasible preferably all bearing [or Carbon and copper] replacement. [remember each position during assembly should add a little oil up, waiting for inspection] finally assembled by hand [or public with] the rotation shaft is smooth. Usually the pump rotation will be easier and smooth, but the pump will be more difficult [when it feels like when tight not tight] # Key: After assembly is not smooth as it must again double-checked 4, mutual comparison method. It is through economic indicators compared with each other to reveal the difference between the number of economic indicators of the hydraulic motor is installed, either the current longitudinal comparison of the above, it may be horizontal in the same industry comparisons between different enterprises servicing a hydraulic motor, can also contact standard values. By comparing identify gaps. And then analyze the reasons for the formation of gaps. 5, the mathematical model method. In modern management science, mathematical models are widely used, especially in the economic forecasting results and management work, because it is not experimental verification Liyuan Hydraulic motors, usually through a mathematical model to analyze and predict the economic decisions that may arise in the . Five more quantitative analysis, ratio analysis is based on trend analysis, structural analysis methods and comparative analysis is an extension of the mathematical model law represents the development direction of the quantitative analysis.
