low specific speed meaning in English
低比速
Examples
- Experimental research on low specific speed roto - jet pump
低比转数旋喷泵的试验研究 - A new type of very low specific speed pump ? roto - jet pump is presented for low flowrate and high head transportation , which is introduced at the end of the thesis
论文最后主要研究了一种隶属于极低比转数离心泵范畴的新型泵? ?旋喷泵，它是一种新型的石油化工用泵，具有流量小、扬程高、流量扬程曲线平缓的特点。 - But there is still a difficult problem present in the low specific speed sewage pumps : with changeable operation points , the motor is often destroyed by overload , which restricts the application of the pump in many fields
但是低比速排污泵在工况多变的场合极易因过载而烧毁电机，这一问题一直没有得到很好的解决，这大大限制了排污泵的使用范围。 - It is a vane pump with high head , small flow and low specific speed , which is smaller , flight and simpler in structure than positive displacement pump mulfistage centrifugal pump , and may handle liquid of high gas or steam content
该泵是一种高扬程，低比速的叶片泵，比容积式泵和多级离心泵体积小、重量轻、机构简单等优点，并可以输送气体或蒸气含量较轻的液体。 - The roto - jet pump is a new kind of very low specific speed pump which is developed in recent years . it is always used in carbin black , food production , chemical industry and deep well mining system to supply the steady outflow with low flux and high pressure
旋转喷射泵是近些年才发展起来的一种极低比转数泵，主要用在碳黑、食品、化工以及深井采矿系统中用以提供小流量高水头的稳定出流。
