新型径向柱塞变量泵恒功率控制机构的方案比较与分析

Comparison and Analysis of the Projects of Constant Power Control Mechanism of a New Variable Displacement Radial Piston Pump

本文详细比较了国内外出现的四种恒功率控制方案 ,给出了系统原理图 ,作了特性比较说明 ,并就工程实用性角度出发设计了一套位移 力矩反馈式恒功率控制机构。给出了其调节特性曲线 。

Four constant power control projects at home and abroad are elabrately compared, system priciple drawings are given out, and characteristic comparision is explained. According to their practic application, a constant power control mechanism with displacement-torque feedback is designed. Its adjusting curve is given out and its design parameters and ideal are cursorily introduced.
