PM VFD Screw Vacuum Pump is a new-generation high-efficiency, energy-saving and environmentally friendly vacuum acquisition equipment, integrating advanced screw rotor technology, permanent magnet synchronous motor and intelligent variable frequency control. Different from traditional reciprocating and ordinary screw vacuum pumps, PM VFD Screw Vacuum Pump adopts a professional micro-oil lubrication design, which ensures excellent sealing and cooling effects while maintaining low oil consumption, avoiding excessive oil pollution of vacuum gas, and meeting the medium-clean vacuum requirements of various industrial processes.
The equipment is equipped with high-precision asymmetric screw rotors processed by five-axis precision machining, with optimized rotor tooth profile and compression ratio design. It achieves stable gas extraction, smooth operation and high vacuuming efficiency, effectively avoiding air leakage and vacuum attenuation. The matched high-efficiency permanent magnet motor maintains ultra-high operating efficiency under various load conditions, with lower heat generation and longer service life compared with conventional asynchronous motors.
The intelligent variable frequency system can automatically adjust the motor speed and pumping speed according to real-time vacuum pressure changes. It intelligently matches the equipment operating power to actual working demands, effectively solving the energy waste problem of constant-speed pumps under intermittent and variable-load working conditions, achieving an energy-saving rate of 25% to 40%. The micro-oil lubrication system reduces friction and wear of core components, lowers operating noise and vibration, and greatly reduces failure rate and maintenance costs.
