Research on stator curve of double acting vane pump
The stator curve is constituted of arcs and transition curves in early period double acting vane pump. In the article, the arc area of stator curve in a vane pump is replaced by an equal velocity curve whose radius is changed according to rotating angle. And advance rising pressure of oil in working room, dynamics characteristic of vane and flow characteristic of pump are studied for vane pump in the article. It is found the gradients of advance rising pressure of oil in working room is decreased, and the dynamics characteristic of vane can be improved, which can reduce the abrasion of vane and noise of pump when the arc area of stator curve is replaced by an equal velocity curve. And have little influence on rat of flow characteristic.
