Rotary piston vacuum pump is used to extract dry gas from sealed containers. If a gas ballast device is used, a small amount of condensable gas can also be extracted. It can be used alone or as a fore pump for Roots vacuum pumps, oil booster pumps, and oil diffusion pumps. However, it is not suitable for gases with excessive oxygen content, corrosive to ferrous metals, and chemical reactions to vacuum oil, nor is it suitable for pumping gas from one container to another as a transfer pump. When extracting gas containing water and a large amount of dust, a dust removal device should be added.
Applicable to vacuum smelting, vacuum heat treatment, vacuum drying, vacuum coating, vacuum impregnation, vacuum distillation, aerospace simulation tests, electrical engineering, photovoltaics, new materials and other vacuum industries.
