Roots vacuum structural features (1) the pump chamber without compression, no exhaust valve. Simple and compact structure, to be pumping gas in the dust and water vapor is not sensitive; (2) relatively low compression Roots vacuum pumps, pumping of hydrogen poor; (3) the shape of the rotor surface for a more complex curve cylinder, processing and inspection more difficult. Roots vacuum at home and abroad in recent years has been rapid development. In refining, petrochemical, electrical, electronics and other industries has been widely used. Gas-cooled Roots pumping main structure: Plum Rotor: To rotor is made of ductile iron casting by high-performance, high-precision CNC machining from Henan Roots vacuum quotes, high precision direct Roots vacuum Henan correct profile design and high-precision processing is the key to ensure 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.
