speed of pumping meaning in English
抽气速度
Examples
- Abstract : as there were leak on contact place between shaft and rotor - body in built - up hollow rotor , dropping discharg gas speed of pump and efficiency applied of oil - sealed sliding vane rotary vacuum pump
文摘:组合式空心转子由于轴头与转子体之间的结合面存在着渗漏，使泵的抽气效率性能下降，从而影响其在应用中的效率。 - With regard to centralized flow regulation , regulating by changing the power has been people ' s common sense and technical current , it mainly includes change the speed of pump and fan , changing their running number and the combine of the two
对于系统流量的集中调节,采用改变动力的方式已成为人们的共识和技术潮流。改变动力的调节主要有改变泵/风机的转速、改变泵/风机联合运行的台数以及二者的结合。 - Through analyzing the figure of energy wasting of pump , the quality in pipes is direct proportion of the speed of pump if the speed of pump is reduced . the power of electromotor fell the cube of the speed of pump . so the energy wasting of constant pressure water supply based on variable frequency speed regulating technology is envident less than the traditional mode is used throttle to supply water
分析水泵工况的能耗比较图，可以看出利用变频调速实现恒压供水，当转速降低时，流量与转速成正比，功率以转速的三次方下降，与传统供水方式中用阀门节流方式相比，在一定程度上可以减少能量损耗，能够明显节能。
