Oil Rotary Vacuum Pump VD / VS / PVD / PKS series

Transcription

1 ow Vacuum Pump Oil Rotary Vacuum Pump VD / VS / PVD / PKS series The oil rotary vacuum pumps are the leading vacuum pumps with high pumping efficiency and consistent pumping performance. They can operate under the pressure between atmospheric pressure to 10Pa or lower. A wide variety of product lineup is available for various kinds of operation.

For the bigger pumps with 5.5k motor or more, there is possibility that pumps don't start running due to insufficient power voltage in case that power capacity is low. Please confirm the power capacity before using bigger pump. Rotary Vane type Explanation image Rotary Plunger type Explanation image Detail of features hat is gas ballast? Gas ballast is a countermeasure when handling condensable gas such as water vapor, etc. Condensable gas is compressed through compression process inside oil vacuum pump, condensed and changed to liquid which mixes with vacuum pump oil. It is left inside in the case of dry vacuum pump. In order to prevent this, it is possible to let condensable gas exhaust without changing from air state to liquid state by ing gas ballast valve and introducing certain amount of air or nitrogen to the working chamber inside pump. ow Vacuum Pump A vane is assembled in the rotor inside the cylinder. The vane compresses and exhausts the gas inside the cylinder. The oil lubricates and cools down the bearing part. It also has a sealing function to secure air tightness of the vane and the cylinder. Excellent in compression efficiency and low vibration. These are the most frequently used vacuum pumps for industrial use. The slide vane sliding on the vane guide part performs piston motion by rotation of eccentric rotor, thereby volume of the space surrounded by slide vane and cylinder is varied and exhausted. Robust and comparatively strong for foreign materials. orkable for long term with appropriate regular maintenance. hat is helium tight type? It is one of optional selections of oil rotation vacuum pump. This type is tested by the helium leak detector and has a leak tightness specification with 1x10-6 (Pa m 3 /s) or below.

2 Oil Mist Trap TM / TMX series The trap to eliminate oil smoke exhausted from oil rotary vacuum pump. Exhaust sound is reduced especially at the time of repeat operation between ultimate pressure and atmospheric pressure. Cartridge type filter makes filter replacement easy.
