根据结构来区分,叶片泵可以分为压力平衡型(卸荷式)和压力非平衡型(非卸荷式)两种类型。在凸轮、转子运动方式上有所不同的凸轮旋转型叶片泵,最近也得到了应用。这些泵虽然在结构上有所不同,但仍然存在许多共性的问题。因此,本文根据最新产品、专利公报以及研究成果(特殊情况除外)所反映的一些情况,来谈谈叶片泵发展的动向。 在经常被提到的关于叶片泵的一些问题中,引起人们注意的是为了实现高压(即高压
According to the structure to distinguish, vane pump can be divided into pressure balance type (unloading) and pressure unbalanced (non-unloading type) two types. Cam rotary vane pumps, which are different in cam and rotor movement, have also been recently applied. Although these pumps are structurally different, there are still many common problems. Therefore, this article based on the latest products, patent gazette and research results (except in special circumstances) reflect some of the situation, to talk about the development trend of vane pumps. Of the many issues that have often been mentioned about vane pumps, attention has been drawn to achieving high pressures (ie high pressures
