Improvement and experimental research on High-pressure Gear Pump based on volumetric efficiency

摘要：

　　Based on the basic structure of typical high-pressure gear pump,a new kind of high-pressure gear pump was designed and applied in water hydraulic transmission system.In this design,the floating plate of typical gear pump is ceramiclized to improve its wear-resisting property;the balance chamber was used to brace and lubricate the axle.Furthermore,the radial unbalanced force induced by the pressure difference of input and output is balanced by the structure of balance chamber.The dynamic characteristic of gear pump is improved and the axel wear is reduced.By using tip relief of tooth flank profile modification,the leakage rate of gear flank is effectively reduced,and the volume efficiency is improved.
