叶片无限薄时凸轮转子式叶片泵的流量持性,作者在文献1、2和3中曾进行了研究、结论指出:凸轮转子过渡曲线采用速度图对称的等加速等减速曲线时,瞬时流量具有脉动性,如果采用速度图不对称的等加速等减速的过渡曲线,或者采用减小小园弧所对中心角的过渡曲线,可以达到降低流量脉动的目的,但不能完全消除流量脉动。实际上叶片有厚度.本文进一步研究叶片厚度对上述三种过渡曲线的凸轮转子式叶片泵流量特性的影响,以及流量不均匀性系数的计算,并进行比较.
When the blade is infinitely thin, the flow capacity of the cam rotor vane pump has been studied in the literatures 1, 2 and 3. The conclusion shows that the instantaneous flow rate of the cam rotor transition curve is The pulsation can be achieved if the transition curve of isokinetic and other deceleration such as speed map is not symmetrical or the transition curve of the central angle to the small circular arc can be used to reduce the flow pulsation but can not completely eliminate the flow pulsation. In fact the thickness of the blade.This paper further studies the effect of blade thickness on the flow characteristics of the cam rotor vane pump with the above three transition curves and the calculation of the coefficient of flow inhomogeneity and compares them.
