Roots liquid ring vacuum system
Roots liquid ring vacuum system is made up of roots pump main pump and water ring pump as series pump. The water ring pump is more advantageous than other vacuum pumps in Roots water ring vacuum unit. It overcomes the shortcomings of limit pressure difference and low pumping rate under certain pressure when a single water ring pump is used. Especially suitable for pumping a large number of condensable steam, especially when the gas-filled oil seal mechanical vacuum pump is not enough to remove condensable steam, or the use of solvent can deteriorate the performance of the pump oil, or the vacuum system does not allow oil pollution more obvious. When equipped with explosion-proof motors and electrical appliances and comply with the corresponding safety rules, flammable and explosive gases can also be extracted.
