In fact, the liquid ring vacuum pump (water ring pump) is a kind of coarse vacuum pump. In this respect, we should pay attention to the fact that the limit vacuum it can obtain is actually 2000-4000Pa. In terms of its series atmospheric ejector, to a large extent, it can actually reach 270-670 Pa. Moreover, the water ring vacuum pump, to a certain extent, will be called a compressor.
Furthermore, we should pay attention to the liquid ring vacuum pump, which will be used as a self-suction pump at the beginning, in fact, it will gradually be used in petroleum, chemical industry, as well as in many industrial sectors such as machinery, mining and light industry, medicine and food.
In many process of industrial production, vacuum filtration, vacuum water diversion and vacuum feeding are common, followed by vacuum evaporation, vacuum concentration, vacuum moisture return and vacuum degassing. In fact, liquid ring vacuum pump itself is The steel frame has been widely used.
Next, we should pay attention to the rapid development of vacuum application technology, liquid ring vacuum pump in the rough vacuum access, has been paid attention to. Because the gas compression in the liquid ring vacuum pump is isothermal to a large extent. In this regard, we should pay attention to the fact that it can extract flammable or explosive gases to a certain extent. In addition, it can also extract dusty or water-bearing gases.
Later, in fact, the liquid ring vacuum pump body will be directly equipped with a suitable amount of water as its working fluid. Moreover, as far as the impeller is concerned, that is to say, when it rotates clockwise in the direction indicated by the impeller, the water will be thrown around directly by the impeller, because the centrifugal force on the liquid ring vacuum pump will form a closed structure.
