Permanent magnet frequency conversion direct-connected two-stage vacuum pump is an advanced vacuum equipment with the advantages of high efficiency, energy saving and reliability.This article will introduce in detail the working principle, structural characteristics, application areas and advantages of this vacuum pump.

Working principle

Permanent magnet frequency conversion direct-connected two-stage vacuum pump uses a permanent magnet synchronous motor to drive a two-stage centrifugal pump for gas extraction, and at the same time, the operating frequency of the motor is adjusted with the help of a frequency converter to achieve precise control of the degree of vacuum.Inside the vacuum pump, the blades of the centrifugal pump rotate to pump the gas from the air inlet. After continuous compression by the first and second stage pumps, the gas is finally discharged into the system, thereby achieving an increase in vacuum.
