Oil booster pump is a kind of steam flow pump, which utilizes the booster pump oil whose saturation vapor pressure is lower than 5 × 10-3Pa at room temperature and produces a large amount of oil vapor after being heated to working temperature, The resulting high-speed steam jet as a medium. The gas being sucked into the oil vapor jet, the jet of gas-containing oil vapor to the pump wall is cooled, the oil vapor is condensed and returned to the pan, while the gas is compressed step by step and finally is pumped away by the foreline pump.

 

The working principle of the oil booster pump is similar to that of the oil diffusion pump, and the gas is still carried by the working jet to achieve the purpose of pumping air. The difference is that the jet of the oil booster pump mainly carries the gas for gas extraction by the viscous friction between the drawn gas and the steam jet. In order for the oil booster pump to work in a region of higher pressure, the steam jet intensity (density) must be increased so that the oil booster pump has a much greater heating power than an oil diffusion pump of the same capacity.

 

Oil booster pump applications similar to the oil diffusion pump, it can be widely used in metallurgy, electronics, chemical, atomic energy industry, space simulation test a variety of vacuum furnace and a variety of process deflation large vacuum coating machine and Other vacuum applications are ideal for obtaining equipment in vacuum. It can be combined with valves, pipes and mechanical pumps to form an efficient vacuum pumping system. Moreover, the working pressure range of the oil booster pump is higher than that of the oil diffusion pump (10 ~ 10-2Pa), so the oil booster pump Pump, but also for the oil pump before the proliferation of pumps, from the pressure effect; In addition, if it is combined with liquid nitrogen and other cooling devices, and baking and other measures to obtain ultra-high vacuum.
