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 with two bearings, using a pair of synchronizing gears, the relative positions of the two rotors remain exactly the same, there are gaps between the rotor and the rotor, the rotor with the pump rotor and the side cover, and therefore the working chamber no friction, no lubrication. Pump rotor is supported with a reliable anti-backlash structure, fan balancing precision helical gears using computer running smooth, low noise, the use of more reliable Henan Roots vacuum phone manufacturers, long-term operation at high differential pressure. ZJP series Roots vacuum pump is a positive displacement pump, also known as a mechanical booster pump Roots, is currently available in one of the major high-vacuum suction device, which works with similar roots blower, is the use of 8 shaped rotor pump housing to rotate in the opposite direction to do the synchronization to complete the intake and exhaust. For the chemical, pharmaceutical and other industries need a lot of water vapor and solvent extraction process in addition, our company ZJP series Roots vacuum pump to a series of improved design, and conventional piston seal to mechanical seals, mechanical seal wear this , long-term stability. The pump with its pumping speed, high vacuum, high smooth running, low noise, ultra-low vibration, can (100 ° left and right) to work under high temperature conditions, without cooling, etc. The majority of users testing and recognition.
