ZJ Series Roots Mechanical Booster Vacuum Positive Displacement Type
The Roots vacuum pump is also known as the mechanical booster which is a positive displacement type pump. It is one of the special pumps which can reach milddle, high vacuum range. Its work principle is similar to the Root fan. Both of them used a pair of rotors, whose shape looks like 8, to achieve the suction and
Main Characteristics of the Roots Pump
· It has larger suction capacity in the wider pressure range(1~1*104Pa).
· There is no oil in the pump chamber, so the pollution of the oil vapor is avoided. ·It has less libration and lower noise.
· It has less mechanical attrition and drive power.
· It is easy to repair and mantanance, so it has lower mantanance charges and longer usage life. ·It can pump the coagulated gases.
· It can not be used separately, a fore pump is needed. Under the atmosphere, it is not allowed to start directly until the inlet pressure reaches the definite pressure that obtained by the fore pump. The water ring vacuum pump, the oil ring vacuum pump and oil seal mechanical pump can be used as the fore pump.
