| Abstract (English): |
In order to solve the check valve response delay and cavitation of the traditional triangle rotary pump after reaching a speed of 700 r/min which result in incapability of increasing the flow rate by increasing the speed, a new rotary pump, an elliptical rotary pump, is designed, and the key performance and design parameters are preliminarily calculated tocompare with the traditional triangle rotary pump which has several drawbacks such as delayedresponse time of the check valve, large fluctuation of the outlet flow rate and short service lift of the face seal. The speed of the elliptical rotary pump is increased by 40%. The total flow rate at the outlet is smoother due to the alternation of three working chambers and the early mixing of the water flow inside the pump body before it is discharged from the outlet. The sliding range of the face seal does not overlap with that of the support seal, thereby improving the service life of the seal. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): |
为解决传统三角转子泵在转速达到700 r/min后出现单向阀响应迟滞以及空化现象, 因而不能通过提高转 速达到增大流量的问题, 设计的一种新型的转子泵--椭圆转子泵, 对关键性能和设计参数进行初步计算, 相比于传 统的三角转子泵的几项弊端, 如单向阀响应时间延迟、出水口流量波动较大, 端面密封使用寿命短等问题。该椭圆转 子泵转速提高 40％;因 3 个工作腔的交替工作, 并在泵体内部提前混合水流后由排水口排出, 因此出水口的总流量 较为平稳;端面密封圈的滑动范围与支撑密封的滑动范围不存在重合, 从而提高了密封圈的使用寿命. [ABSTRACT FROM AUTHOR] |
