High-Speed roots Vacuum Pump Operation

The entire series is equipped with QT500 high-strength ductile iron rotor, with a tensile strength of 500 MPa and an elongation rate of 15%.

The composite sealing structure technology completely solves the emulsification and leakage problems of vacuum pump oil, making it more stable and reliable.

The accessories are precisely manufactured by imported processing centers, with strict control of the gaps between rotors and between rotors and the pump body, ensuring stable operation when the gap is less than 0.05mm.

Independently produced and manufactured, it has over 40 vacuum-related patents, has been rated as a national high-tech enterprise and a science and technology enterprise, and has passed ISO9001 quality management system certification.

The spiral jacket cooling method ensures excellent heat exchange efficiency, fully guaranteeing the low-temperature lubrication performance of the lubricating oil, thereby extending the service life of gears, bearings and mechanical seals.

The use of precision gears (5-level accuracy) for rotation and precision couplings for connection ensures the smoothness and accuracy of the pump's operation, with extremely low running noise.

High-strength, high lateral force precision bearings from fully imported (SKF/NSK) are selected and lubricated by splash lubrication, which can greatly extend the pump's service life.

A bypass valve is set inside, allowing the Roots vacuum pump and the preceding vacuum pump to almost simultaneously start under atmospheric conditions to shorten the pumping time.
