Characteristics of industrial roots water ring vacuum unit
Roots water ring vacuum unit is composed of Roots vacuum pump as the main pump and water ring vacuum pump as the front pump in series.
For roots water ring vacuum unit, it is more advantageous to select water ring vacuum pump as the front pump than other vacuum pumps. It overcomes the limit pressure difference when a single water ring pump is used (the limit pressure of the unit is much higher than that of the water ring pump) At a certain pressure, the defect of low air extraction rate, together with the advantages of rapid operation of roots pump, has a larger air extraction rate, especially suitable for pumping a large number of condensable mixed fatty acid steam.
Characteristics of roots water ring vacuum unit
① In the unit, there is a certain gap between the rotor and the pump cavity, and between the rotor and the rotor, so they do not touch each other and do not need oil lubrication
② The rotor of roots pump has a good geometric symmetry, which can improve the speed of rotation, and thus can produce a large pumping speed pump with compact structure
③ Roots vacuum unit has small vibration and large volume during operation
④ In the cavity of Roots vacuum pump, there is no compression phenomenon like mechanical vacuum pump, so it does not need exhaust valve. Because of this, the condensable fatty acid steam can be removed
⑤ When roots vacuum unit operates, it can start quickly, reach the limit vacuum in a short time, with small power and low maintenance cost
⑥ Roots pump has a large pumping speed in a wide pressure range (1-1000 PA), which can discharge the distilled gas quickly
