泵用微连通对称双卸荷槽及其困油与流量特性OA北大核心CSTPCD
Oil trapping and flow rate characteristics under micro-connection and symmetry layout of relief grooves in external gear pump
为了充分提高外啮合齿轮泵的困油性能和完善双卸荷槽的现有设置理论,提出了一种双卸荷槽微连通对称设置的创新结构,并以常规无连通对称设置的双矩形卸荷槽为例,依次给出了创新结构的实现方法,构建了困油压力和理论流量的计算模型,比较分析了常规结构和创新结构下的困油压力、排量损失以及流量脉动质量等.结果表明:啮合点位置越接近最小困油容积位置,创新结构下的卸荷面积越大,突出解决了常规结构下该处的零卸荷面积问题;通过充分缓和常规结构下的困油压力,创新结构有效地避免…查看全部>>
In order to fully improve the oil trapping performance of external gear pump and perfect the existing setting theory of double relief grooves,an innovative structure of micro-connection and symmetry layout of relief grooves was proposed.Taking the no-connection and symmetry layout of conventional rectangular relief groove as an example,firstly,the embodiment method of innovative structure was given,secondly,the calculation model of oil trapping pressure and …查看全部>>
