The 2X series vacuum pump is of two-stage structure, its operation performance consists of two parts, high-pressure stage and lowpressure
stage. Its suction port is connected with the vacuum container or other vacuum equipments to helps intaking or draining the
gas inside the container during operation. When the equipment is in vacuum, the high-pressure stage drain valve will be closed, 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 get a certain extent vacuum. The technical parameter of the
pump is 6¡Á10-2Pa. According to the user's operation requirements, to equip a vacuum booster pump, and this pump is used as a
backing pump. Since the booster pump increased suction force, accompanied with the continuous suction of the backing pump, the
equipment will obtain higher vacuum percentage.
