Type 2X double-stage rotary vane series vacuum pump
¡ö Application
    The 2X series vacuum pump is of double-stage structure, whose operation performance consists of two parts, that is high-pressure stage and low-pressure stage. Its suction port connects the vacuum container or other vacuum equipments and helps to intake or drain the gas in the container during operation. When the equipment is in vacuum, the drain valve vane of high-pressure stage will close, then the gas suctioned by the high-pressure stage will be transferred to the second stage, after that, the gas will be suctioned and drained through the second stage, so that the vacuum equipment can obtain certain vacuum. The technical parameter of the pump is 6¡Á102Pa. A vacuum booster pump can be equipped according to the user's operation requirements, and this pump is used as a fore pump. Since the booster pump has an increased suction force, and with the continuous suction of the fore pump, the equipment will obtain higher vacuum percentage.
