Gas capture pump type and model Daquan

As a vacuum pump that allows gas molecules to be adsorbed or condensed on the inner surface of the pump, with the continuous development of China's light industry, heavy industry, the medical profession and other fields, the use of vacuum pumps is more and more widespread . Knowing the type of gas capture pump is crucial to the development and enhancement of such products. Gas trapping pump 1. Sorption pump, which is a trapping vacuum pump that relies on the physical adsorption of adsorbents with a large surface area, such as porous substances. For example molecular sieve adsorption pumps. 2. A getter pump, a vacuum pump that uses a getter to chemically trap gas. Getters are usually metals or alloys that exist in the form of lumps or deposited fresh films. For example, titanium sublimation pump and aluminum-zirconium-aluminum suction pump of this type. 3 getter ion pump, which is to make the ionized gas through the electric field or the role of electromagnetic field adsorption on the surface of the gettering material, in order to achieve the purpose of pumping. It has the following two types. 1) Evaporation Ion Pump: A type of vacuum pump in which ionized gas is adsorbed on a getter material sublimated (or evaporated) in an intermittent or continuous manner over an inner wall of a pump to effect aspiration. For example, orbital ion pump (or ballistic titanium pump). 2) Sputtering Ion Pump: A vacuum pump in which the ionized gas in the pump is adsorbed on the getter material that is continuously splashed out by the cathode to achieve the purpose of pumping. 4. Cryogenic pump, which is the use of low temperature surface capture gas vacuum pump. In summary, a wide variety of gas capture pumps, for this reason, different types of gas capture pump will have some of the features. However, with the development of our economy and the constant improvement of science and technology, the development of gas-trapping pumps is also becoming more and more suitable for the needs of production development. It is believed that in the near future, gas-trapping pumps will surely become the main force of vacuum pumps .
