定子是叶片泵的重要零件之一。它加工的好坏,不仅影响叶片泵的流量、压力振摆、产生冲击和噪音,而且加快磨损,大大影响叶片泵的寿命。而定子过渡曲线的加工则是影响性能的重要因素。目前,定子应用的过渡曲线有阿基米德螺线、叶片径向加速度按正弦规律变化的曲线(简称正弦曲线)、叶片径向加速度按余弦规律变化的曲线(简称余弦曲线)和叶
The stator is one of the important parts of the vane pump. Its processing is good or bad, not only affects the vane pump flow, pressure swing, resulting in impact and noise, but also to speed up wear and tear, greatly affect the life of the vane pump. The stator transition curve processing is an important factor affecting performance. At present, the curve of application of the stator with Archimedes spiral, the blade radial acceleration according to the law of sinusoidal curve (referred to as the sinusoidal curve), the radial acceleration of the blade according to cosine law of the curve (referred to as the cosine curve) and leaves
