Gas-cooled Roots pumping main structure: Plum Rotor: To rotor is made of ductile iron casting by high-performance, high-precision CNC machining by Roots vacuum quotes, high precision Roots vacuum wholesale prices, right profile design and high The process is the key to ensure the accuracy of the overall performance. Precision rotor balancing test. Synchronous Gear: Gear is one of the most important part of the synchronization Roots vacuum pump, which is used to ensure synchronous rotation of the two rotors to maintain a certain gap between the rotor. Gear surface by high-frequency quenching, and grinding is made from a special high-precision, low noise. Roots vacuum Main features: 1, can be exhausting condensable gases. 2, can not be used alone Roots vacuum phone manufacturers, you must configure the front pump. Before they start is not allowed to start at the popular pressure, before the pump will be pressure pumped Roots pump inlet pressure allowed. Forepump generally water ring vacuum pump, oil ring vacuum pumps, mechanical seal pumps. 3, except for the pumping characteristics of water vapor and organic solvents has been improved to solve the problem of emulsified oil bearing cavity pump.
