An autoclave, a rectifier… a centrifuge… diffusion pump, desiccator.
Diffusion pumps, cryopumps and adsorption pumps 8414 10 81 PCE.
For example, benefits of switching from oil diffusion pumps to STP turbo molecular pumps. .
The diffusion pump is widely used in both industrial and research applications.
The vacuum system is composed of mechanical pump, roots pump, and diffusion pump.
Most modern diffusion pumps use silicone oil or polyphenyl ethers as the working fluid.
The configuration is equipped with the molecular pump system(Diffusion pump and condensate pump system is selectable)….
For 100 years, the diffusion pump has been almost irreplaceable for many high-vacuum processes.
XZ series rotary vane vacuum pump can be used independently,which also can be as booster pump, diffusion pump, molecular pump and titanium pump's pre-pump.
In modern textbooks, the diffusion pump is categorized as a momentum transfer pump. .
Initially a low or roughing vacuum is achieved with either a rotary vane pump or diaphragm pumps bringing the TEM to a sufficiently low pressure to allow the operation of a turbomolecular or diffusion pump which brings the TEM to its high vacuum level necessary for operations.
In modern text books, the diffusion pump is categorized as a momentum transfer pump. .
Diffusion pumps use a high speed jet of vapor to direct gas molecules in the pump throat down into the bottom of the pump and out the exhaust.
Slide valve pump, roots pump, diffusion pump and maintaining pumpoptional.
Oil diffusion pumps==The oil diffusion pump is operated with an oil of low vapor pressure.
Although its use has been mainly associated within the high-vacuum range(down to 10-9 mbar), diffusion pumps today can produce pressures approaching 10-10 mbar when properly used with modern fluids and accessories.
Unit: diffusion pump KT-800(Zhen Hua), ZJY-600 2X-70 roots pump, mechanical pump, pump maintenance 2X-8.
These general purpose pumps are used in a high variety of vacuum technology applications and are proving their efficiency in industrial production as well as in research, generating pressures in the low and medium vacuum range,as well as backing pumps in combination with other types such as Roots pumps, diffusion pumps, turbo-molecular pumps or cryo pumps. .
Modernization of diffusion pumps offer a high potential for energy saving, as in metallurgical applications of vacuum furnaces.
Applications==Pumps that use oil either as their working fluid(diffusion pumps), or as their lubricant(mechanical rotary pumps), are often the sources of contamination in vacuum systems.
Diffusion pumps cannot discharge directly into the atmosphere, so a mechanical forepump is typically used to maintain an outlet pressure around 0.1 mbar.
In addition, Oerlikon Leybold Vacuum has improved on the established Diffusion pump technology and created a modern and retrofit able power control unit which offers a reduction of the energy demand of these pumps by up to 30.
Gaede used the name diffusion pump since his design was based on the finding that gas cannot diffuse against the vapor stream, but will be carried with it to the exhaust.
Slide valve pump& roots pump& diffusion pump& maintaining pump optional: molecular pump, deep cold pump, deep cold system.
The features that make the diffusion pump attractive for high and ultra-high vacuum use are its high pumping speed for all gases and low cost per unit pumping speed when compared with other types of pump used in the same vacuum range.
Mineral oils(LEYBONOL LVO 500 and LVO 510) for diffusion pumps are closely toleranced fractions of a high quality base product distilled with particular care.
LEYBONOL pump fluids for oil diffusion pumps must exhibit a low vapor pressure at room temperature and must be able to resist thermal decomposition and oxidization.
Rotary pump& roots pump& diffusion pump& maintaining pump optional: molecular, deep cold pump or deep cold system.
By upgrading the vacuum pumping technology(from diffusion pumps to STP turbo molecular pumps) we have reduced the energy consumption of this process by up to 95%, with a CO2 reduction of 22.6 tonnes per year.
In the 8 stage of magnetron sputtering(usually 0.5Pa), diffusion pump(must be added to the throttle valve) and the pumping speed is only the nominal value of 1/6~1/5, the molecular pump speed for the nominal value of 50~70%, so the coating activity of gas partial pressure were 5~6 times and 1.5~2 times of the bottom pressure.
