The roots water ring vacuum system is a roots pump as the main vacuum pumps, water ring pump for the front class pump in series. Roots water ring vacuum unit selection of water ring pump as a pre-pump than other vacuum pump systems is more favorable, it overcomes the use of a single water ring when the limit pressure difference (the unit's limit pressure than the water ring pump has greatly improved) In a certain pressure under the low pumping rate of the shortcomings, while retaining the Roots vacuum pump system can work quickly, the advantages of a larger pumping rate. In particular, it is possible to adapt to the extraction of large amounts of condensable vapors, especially when the gas-laden seal mechanical vacuum pump is insufficient to remove condensable steam, or the solvent used can deteriorate the pump oil and affect the performance, or the vacuum system does not allow oil contamination Time is more obvious. When equipped with explosion-proof motor and electrical appliances and comply with the corresponding safety rules, but also remove the flammable and explosive gas.
