Sliding valve vacuum pump is a kind of oil-sealed variable displacement mechanical pump. It is an ideal vacuum acquisition equipment for pumping out gases from specific sealed containers. It can directly obtain a vacuum below 1 Pa. It can also be used as the front pump of other vacuum acquisition equipment to obtain a higher vacuum. Because the pump keeps a non-contact rolling motion between the sliding valve and the pump chamber during the working process, it has the characteristics of dirt resistance, corrosion resistance and durability. The bearing of the pump is lubricated with grease and separated from the pump oil, so it can be used to extract gas containing a small amount of dust. At present, the pump has been widely used in metallurgical, chemical, pharmaceutical, textile, semiconductor, petroleum, food and atomic energy fields.
Note: The pump is made of ferrous metal and belongs to a more sophisticated equipment. Its main parts are immersed in vacuum pump oil, so it is not suitable for pumping poisonous, explosive, chemical and corrosive gases to the pump oil, nor for pumping gases from one container to another. When removing the gas containing a large amount of dust, dust removal devices should be installed.
