Oil Diffusion Pump Working Principle

They are employed in high vacuum technology to evacuate vacuum cham bers.

Oil diffusion pump working principle. It is also highly effective in producing vacuums 10 10 to 10 2 mbar even in poor conditions where reactive gases or gases with excess particles are present. In this blog we will explain the working principles of oil diffusion pumps including how to apply and control them in vacuum systems the typical dos and don ts and provide several application examples. The working principle of a diffusion pump depends on the interdiffusion phenomenon between two different gasses. The diffusion pump is known as a fluid entrainment pump and works in a completely different manner.

The working principle of oil diffusion pump is similar to that of steam jet pump. The fluid is then moved to another location and cooled. Diffusion pumps have two primary factors that make the pump work. The cooling forces the air molecules to be released.

After that langmuir had developed the practical and commercial version of this diffusion pump. The diffusion pump uses the vapor of a boiling fluid to capture air molecules. The oil diffusion pump function principle the function principle was founded by wolfgang gaede in 1915. Gaede had developed this type of pump in the year 1815.

It has a very simple operating principle but can be very challenging to design and manufacture due to the tight constraints these two factors work under. Heat and internal geometry. The dip series pumps are water cooled and utilize the oil diffusion principle in their operation. A diffusion pump is a stainless steel chamber that vary in size based on the application.

Whatever may be the type of a diffusion pump but the basic principle is the interdiffusion between two gasses.
