喷射泵就是利用汽(气)流或水流高速喷射而获得真空的一种设备。一般根据喷射的工作流体不同,而分别为蒸汽、空气和水喷射泵。它是一种抽气、抽水、抽尘的真空设备,因其结构简单、制造容易、工作稳定,操作方便等优点而在化工、医药、制糖工业比较普遍的应用。目前在冶金矿山的选矿厂采用的真空设备大部分是水环式真空泵,它的日常检修工作量比较大,尤其在较高的真空度下工作时,泵的寿命较短。另一方面,一些小型选矿厂,也常因缺乏机械真空泵而造成脱水困
Jet pump is the use of steam (gas) flow or high-speed water jet to obtain a vacuum device. Generally depending on the working fluid injected, steam, air and water jet pumps, respectively. It is a vacuum, pumping, pumping vacuum equipment, because of its simple structure, easy manufacture, stable work, easy operation and other advantages in the chemical, pharmaceutical, sugar industry more common applications. At present, the vacuum equipment used in the metallurgical mine concentrator is mostly a water ring vacuum pump, and its daily maintenance workload is relatively large, especially when working under a higher degree of vacuum, the pump has a shorter life span. On the other hand, some small-scale concentrators often suffer from dehydration due to lack of mechanical vacuum pumps
