ZJH belt relief Roots Roots vacuum pump manufacturer in Henan, the original basis (ZJ, ZJP) improved fourth generation of new products, using a pair of eight rotors constant reverse rotation of the pump chamber generating suction and discharge action. Each rotor is supported by two bearings, using a pair of synchronized gear Henan Roots vacuum supply prices, the relative position of the two rotors remain unchanged between the rotor and the rotor, the rotor and the pump body, rotor and side cover has gap, and thus the working chamber without friction, without lubrication. Pump rotor is supported with a reliable anti-backlash structure, blades precision helical gears using computer balancing, smooth running, low noise, Henan Roots vacuum phone manufacturers, the use of more reliable Roots vacuum pump, long-term operation at high differential pressure. ZJ Roots vacuum pumps, the use of CNC machining center, the body and the side cover, are used between the cover and the side cover "O" ring sealed, cylindrical pin positioning, parts exchange of good performance, easy maintenance, pump an air intake vent design three, user-friendly installation. Roots pumps can not be used, only the series before the pump can be used to select pump, seal pumps, liquid ring pump as a backing pump, it is worth mentioning that, elected by pump, liquid ring pump as a backing pump , especially for the occasion in addition to a large number of suspicious pumping gas.
