Study on correction coefficient of flow kinetic energy near groyne 丁壩附近區(qū)域水流動能修正系數(shù)研究
In this paper , on the basis of the analysis of gear pimp working principle , the mechanism of flow pulsation and methods of reducing flow pulsation are pulsation are studied . the computing formula of transient flow rate and the coefficient of flow pulsation are deduced . the relationship between the gear pump flow pulsation and the construction parameters of the gear is studied 本文在齒輪泵工作原理和流量脈動產(chǎn)生機(jī)理的基礎(chǔ)上,首先從理論上推導(dǎo)了齒輪泵瞬時流量和流量脈動系數(shù)的數(shù)學(xué)模型,分析了齒輪泵的輸出流量脈動與泵齒輪各結(jié)構(gòu)參數(shù)之間的關(guān)系,并對某型齒輪泵進(jìn)行仿真分析研究,給出了齒輪泵的流量脈動分析結(jié)果。
