柱塞泵中柱塞摩擦副泄漏流量的分析

Flowrate Analysis of the Piston Friction Pair in Hydraulic Piston Pump

考虑到柱塞密封长度的变化 ,对柱塞与缸孔间环形间隙流动流量公式进行了修正 ,得出了修正系数的计算公式 ,为柱塞泵 (马达 )

In this paper,the flowrate formula of the annular clearance between piston and cylinder in hydraulic piston pump is revised because the seal length of piston becomes different.The revised coefficient makes things convenient for volumetric efficiency calculation on hydraulic piston pump.
