The working principle of water ring vacuum pump
Water ring vacuum pump (referred to as water ring pump) is a kind of rough vacuum pump, it can obtain the ultimate vacuum of 2000~4000Pa, series atmospheric ejector up to 270~670Pa. The water ring pump can also be used as a compressor, called a water ring compressor, which is a low-pressure compressor with a pressure range of 1~2 × 105Pa gauge pressure. Water ring pump was originally used for self-priming pumps, and then gradually used in petroleum, chemical, machinery, mining, light industry, medicine and food and many other industrial sectors. In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture and vacuum degassing, water ring pump has been widely used. Due to the rapid development of vacuum application technology, the water ring pump has been paid attention to in the rough vacuum. Since the gas compression in the water ring pump is isothermal, it can pump out flammable and explosive gases, and in addition to dust and water-bearing gases, the application of water ring pumps is increasing.
