The advantages and disadvantages of water ring vacuum pump
|Introduction:Water ring vacuum pump (hereinafter referred to as water ring pump) is a kind of coarse vacuum pump, it can get the limit of vacuum for 2000 ~ 4000 pa, pa series air ejector can reach 270 ~ 270.Water ring pump can be used as a compressor, also known as water ring compressor, belongs to low pressure compressor, the pressure range of 1 ~ 2 x 105 pa gauge pressure.
Originally used as liquid ring vacuum pump self-priming pump, and then gradually used in petroleum, chemical industry, machinery, mining, light industry, medicine and food and many other industries.In many industrial production process, such as vacuum filter, vacuum water diversion, vacuum feed, vacuum evaporation, vacuum concentration, vacuum resurgence and vacuum degassing, water ring pump is widely used.Due to the rapid development of vacuum technology, water ring pump in crude vacuum has been paid great attention by people.Because water ring pump in the gas compression is isothermal, so the pumping flammable, explosive gas, it also can smoke in addition to the dust, water, gas, therefore, water ring pump application is increasing.
Water ring vacuum pump working liquid and other suitable liquid, can be applied either working liquid are collectively referred to as liquid ring vacuum pump.Water ring vacuum pump is the most common liquid ring vacuum pump, the most widely used a pump.
Firstly :Water ring pump compared with other types of mechanical vacuum pump has the following advantages:
Secondly: Water ring pump also has its disadvantages compared with other pump like rotary vane vacuum pump and so on.
