For most people, the closed cycle vacuum pump is undoubtedly an unknown number. Well, let's not talk about how it works. Maybe a lot of people don't even know what it does. Let's introduce the working principle of closed cycle vacuum pump so that we can fully understand it.
The closed circulating vacuum pump is composed of roots pump, which is connected in series with the front pump. The water ring pump selected for closed cycle vacuum unit is more advantageous than other vacuum pumps because it not only overcomes the limit pressure difference limit when using single water ring pump (the unit limit pressure is much higher than the limit pressure). Under a certain pressure, the water ring pump has low pumping rate and retains its shortcomings. Roots pump works quickly and has the advantages of high pumping rate. Especially when the vacuum pump can not discharge condensed steam, or the solvent used will make the pump oil worse and affect the performance, or when the vacuum system does not allow oil polling, it is more obvious. Dilute. If equipped with explosion-proof motors and electrical appliances, and comply with the corresponding safety regulations, they can also remove flammable and explosive gases.
Therefore, the closed cycle vacuum pump can be widely used in vacuum distillation, vacuum evaporation and crystallization in chemical industry, freeze-drying in food industry, vacuum drying in pharmaceutical industry, polyester chip in light textile industry.
