Roots water ring vacuum units
Detailed introduction
Product Overview
Roots water ring vacuum unit selects water ring pump as the fore stage pump is more favorable than other vacuum pumps, it overcomes the disadvantage of low pumping rate under a certain pressure due to the limit pressure difference when single water ring pump is used (the limit pressure of the unit has been greatly improved compared with that of the water ring pump), and at the same time it retains the advantages of Roots pump which can work rapidly and has a larger pumping rate. Especially can adapt to pumping out a large number of condensable vapors, especially when the gas town oil-sealed mechanical vacuum pump to exclude condensable vapors ability is not enough, or the use of solvents can make the pump oil deterioration and affect the performance, or the vacuum system does not allow the oil contamination of the time is more obvious. When equipped with explosion-proof motors and electrical appliances and observing the corresponding safety rules, they can also pump out flammable and explosive gases.
Product characteristics
Roots vacuum units in general, the selection of water ring pumps as a pre-stage pump than other vacuum pumps is more favorable, which is mainly due to its ability to pump out a large number of condensable vapors, especially when the gas town of oil-sealed mechanical vacuum pumps to exclude condensable vapors is not enough, or the use of solvents to make the pumping oil deterioration and affect the performance of the vacuum system does not allow oil contamination is more obvious when!
Product use
Used in vacuum distillation, vacuum evaporation, dehydration and crystallization in chemical industry; freeze-drying in food industry; vacuum drying in pharmaceutical industry; polyester slicing in light textile industry; high altitude simulation test, etc. in the pumping vacuum system.
