PRINCIPLE
The vacuum pump section of each stage in this machine is constructed with a Roots type pump. The pump consists of two rotors having a three-lobe shaped cross section each, and mounted to parallel shafts, while keeping a slight clearance against the inside wall of enclosing casing, and also between rotors. The compression function is as follows.
  1. The suction gas into the inlet of vacuum pump is compressed by rotation of rotors
  2. The discharged gas divided into two portions, one portion of gas flows into back-flow cooling port and another portion flows into second stage.
  3. The discharged gas from second stage is transferred into cooler.
  4. A part of cooled gas flows into back-flow cooling port of second stage. And another gas transferred to third stage.
  5. The discharged gas from third stage is transferred into cooler. A part of cooled gas flows into back-flow cooling port of third stage.
  6. And another gas is discharged to atmosphere.
