Applications

1. Vacuum distillation: In the chemical and petroleum industries, vacuum distillation is used to separate and purify mixtures of liquids with different boiling points. Two-stage rotary vane pumps are used to reduce the pressure in the distillation column, allowing the liquids to boil at lower temperatures. This helps to avoid thermal degradation of the components and improves the efficiency of the separation process.
2. Vacuum drying: In the food, pharmaceutical, and chemical industries, vacuum drying is used to remove moisture from materials at low temperatures. Two-stage rotary vane pumps are used to create the vacuum required for the drying process. By reducing the pressure, the boiling point of water is lowered, allowing the moisture to be removed without damaging the heat-sensitive materials. This is particularly important in the production of pharmaceuticals, where the integrity of the active ingredients needs to be maintained.
3. Vacuum coating: In the process of vacuum coating, such as the deposition of metal films, oxide films, and nitride films on the surfaces of materials, two-stage rotary vane pumps are used to create a high-vacuum environment. This ensures the purity and quality of the coating by preventing air and other impurities from interfering with the deposition process. For example, in the production of optical coatings for lenses, the precise control of the vacuum environment by two-stage rotary vane pumps is crucial to achieve the desired optical properties.
