Get PriceThe term roughing/backing pump is used because the pump is required to perform two fairly distinct operations. The pump has to, first, rough pump the chamber from atmospheric pressure to a low enough pressure to allow the high vacuum pump to operate, and then it has to revert to a secondary position where it supports the high vacuum pump by providing a low enough pressure at the high vacuum pump…
Get PriceUltra High Vacuum: 10-9- 10-12Tor. The transition from atmospheric pressure to the bottom of the UHV range (approx. 1 x 10-12Torr) is a dynamic range of almost 1015and well beyond the capabilities of any single pump. Indeed, to get to any pressure below 10-4Torr requires more than one pump.

Get Price2021-7-8 · Mechanical (Roughing) Pump. Mechanical pumps are used to achieve low to medium vacuum and back high vacuum pumps. Some use oil, while others are 'dry' (oil-free). Rotary Vane Pump. The rotary vane pump has a simple operation: gas enters through an intake, is compressed by a rotating vane, then removed through an exhaust on the other side.
Get PriceIn addition, most turbo pump manufacturers do not recommend placing LN 2 traps above their pumps. The argument is, when the system is vented, water frozen on the trap's surface thaws and drips into the pump. While it's reasonable to protect the pump, if there is sufficient water to drip, perhaps an in chamber LN 2 trap should be used. Baffles
