As the core component of energy conversion in the hydraulic system, the matching degree of the hydraulic motor with the existing hydraulic pipeline depends on the coupling relationship between the structural characteristics and fluid dynamics. The port size, connection method and sealing form of the hydraulic motor directly affect the physical adaptability of the pipeline, and the geometric tolerance and thread matching accuracy of the interface flange determine the reliability of the installation connection. The internal flow channel design affects the pressure-flow dynamic response matching with the pipeline system by optimizing the fluid resistance distribution.
The adjustable displacement range of the hydraulic motor needs to form a corresponding relationship with the pipeline pumping capacity. Excessive displacement difference will cause the system pressure fluctuation to exceed the adjustment threshold. There is a timing coordination requirement for the response speed of the rotation direction switching and the signal delay of the pipeline valve control unit, which directly affects the continuity of the action. The leakage suppression ability and the pipeline sealing level form a series effect, and the accumulation of micro-leakage may change the overall volumetric efficiency of the system.
Fluid medium compatibility involves the matching of the corrosion resistance of the material and the cleanliness requirements of the oil, and the metal surface treatment process determines the probability of particle adsorption. When the residual vibration of the pipeline is transmitted through the hydraulic motor housing, the difference in structural resonance frequency may amplify the system noise. The matching degree of the thermal expansion coefficient affects the connection sealing after long-term operation, and the deformation caused by the temperature gradient may cause abnormal matching clearance. The pressure-flow curve calibration in the debugging stage needs to consider the compensation for pipeline loss along the way to ensure the accuracy of parameter linkage under rated conditions.
