双斜齿轮泵工作原理及其特性分析

Study on Working Principle and Property of Double Helical Gear Pump

斜齿齿轮泵在保持直齿齿轮泵优点的基础上降低了压力脉动和噪声,但由于附加轴向力的存在限制了工作压力的提高。通过分析双斜齿轮泵的工作原理及其性能,得出双斜齿轮泵既能锐减单组斜齿轮泵的附加轴向力的不良影响,又能改善了瞬间排量和流量脉动,更具优良性能。

Helical gear pump retains common advantages of gear pump. It also has low pressure pulse and low noise. But its working pressure is confined by accessory axial thrust. The working principle and property of double helical gear pump are analyzed. The conclusion that double helical gear pump can not only drastically deduct the mal- influence of accessory axial thrust, but also ameliorate the instant displacement and flow pulse.
