Vacuum Pump Package Unit for High Efficiency

The water ring vacuum unit is composed of Roots pump as the main pump and water ring pump as the backing pump in series. The water ring pump selected for the water ring vacuum unit is more advantageous than other vacuum pumps as the backing pump, because it not only overcomes the limit pressure difference when a single water ring pump is used (the limit pressure of the unit is much greater than the limit pressure of the water ring pump). Large improvement), the shortcomings of low pumping rate under a certain pressure, and at the same time, the Roots pump can work quickly and has the advantages of relatively large pumping rate. It can be adapted to extract a large amount of condensable steam, especially when the gas ballast oil seal mechanical Vacuum Pump has insufficient ability to remove condensable steam, or the solvent used can deteriorate the pump oil and affect performance, or the vacuum system does not allow oil pollution More obvious. If equipped with explosion-proof motors and electrical appliances and comply with the corresponding safety rules, it can also extract flammable and explosive gases
