【摘要】 针对工作介质的可压缩性,以VQ45型泵为例,在考虑了预升、卸压闭死区和减振阻尼槽的引油作用时,对双作用子母叶片泵瞬时流量进行了仿真分析,计算了流量不均匀系数,找出了双作用子母叶片泵瞬时流量脉动的主要影响因素是泵的工作压力和工作介质的体积弹性模量.更多还原

【Abstract】 Aimed at the compressibility of working medium in pump and taking into account the process of pre-loading and pre-unloading as well as the damping action of vibration-reducing slot in exampled VQ45 pump, the simulation of transit flow in double-acting pump with composite vanes is conducted and, then, the unevenness coefficient of flow is computed. It is found finally that the origin of flow oscillation in double acting pump with composite vanes is rested with the pump working pressure and elastic modulus of the working medium.更多还原
