1. Mechanical Vacuum Pump
Mechanical vacuum pumps are the most common type. They compress gas through mechanical motion and are typically used to extract impurities from the air.
Features:
Simple structure, easy to use, and require no additional liquid medium.
Suitable for extracting gases that do not contain corrosive or polluting substances.
Applications: Widely used in laboratory vacuuming, gas collection, and other applications.
2. Rotary Vane Vacuum Pump
Rotary vane vacuum pumps use rotating blades to expel air, gradually extracting the air from the container to achieve a vacuum.
Features:
High efficiency and fast pumping speed.
Low noise, suitable for applications requiring continuous operation.
Applications: Commonly used in industrial vacuuming, gas treatment, and other applications.
3. Water Ring Vacuum Pump
Water ring vacuum pumps use a closed, annular chamber formed by water to compress gas and discharge it through liquid.
Features:
Suitable for extracting environments containing water vapor or corrosive gases.
Excellent operating stability and the ability to withstand high pressures.
Applications: Suitable for industries with special requirements for exhaust gases, such as chemical processing and sewage treatment.
4. Dry Vacuum Pump
Dry vacuum pumps utilize no liquid lubrication and rely entirely on mechanical mechanisms to generate vacuum, eliminating the risk of liquid leakage.
Features:
Environmentally friendly and clean, suitable for applications requiring high cleanliness;
Suitable for extracting gases that do not contain water vapor.
Applications: Food processing, pharmaceuticals, semiconductors, etc.
