Traction molecular pump advantages and disadvantages

Traction molecular pump is a kind of pump chamber contains a free-wheeling rotor, and the rotor with grooves around the same time separated by a baffle device. Each groove is equivalent to a single-stage molecular pump, the inlet of the next stage is connected with the outlet of the previous stage. 0.01mm clearance between the rotor and the pump housing, when the gas molecules from the entrance into the pump chamber, carried by the rotor to the outlet side, the exhaust pipe by the foreline pump away. With the increase of the Vacuum pump market, the research on such products as traction molecular pumps can start from its advantages and disadvantages. Traction molecular pump traction molecular pump advantages: 1, traction molecular pump starting time is short; 2, in the molecular flow state has a high compression ratio; 3, traction molecular pump can remove all kinds of gas and steam, especially for pumping Heavier gas; traction molecular pump Disadvantages: 1, traction molecular pump pumping speed is small; 2, traction molecular pump sealing gap is too small; 3, traction molecular pump poor reliability, easy to mechanical failure, etc., In fact, rarely used; 4, traction molecular pump because of its particularity, was once the structure and manufacturing simple, pumping speed large diffusion pump replaced; but with the current vacuum pump market demand continues to increase traction The speed of molecular development and innovation has also been increasing, and its characteristics have become more closely linked to the needs of people's production as technological reforms have taken place. Although the traction molecular pump in the current use of the range is subject to certain restrictions, but with the development of the vacuum pump faster and faster, I believe that with the efforts of professionals, traction molecular pump will be greatly changed, I believe in the family of vacuum pumps Lane, traction molecular pump or will have their own place.
