Dry Vacuum Pump
Dry Vacuum Pump
Application: Hospitals, Pharmaceutical Industries, Medical.
A vacuum pump is a mechanical device designed to remove air, gas, or other fluids from a closed container or space to create a vacuum or lower pressure environment. It accomplishes this by drawing air or gas out of the container, creating a partial vacuum inside.
Vacuum pumps come in various types, such as rotary vane pumps, diaphragm pumps, and centrifugal pumps, each suited to specific vacuum level requirements and applications.
Dry Vacuum Pump
Historical Overview:
Vacuum pumps have a rich history of development dating back to the 17th century when primitive vacuum techniques were used in scientific experiments. Over time, this device evolved into the sophisticated pumps used today .
Vacuum Pumps:
- Positive Displacement Pumps: This category includes pumps that physically capture and deliver air from the vacuum chamber.
- Rotary vane vacuum: pumps use rotary vanes to compress and move air molecules.
- Diaphragm Vacuum Pump: The diaphragm vibrates to create a vacuum.
- Piston Vacuum Pumps: Pistons move into the cylinder to create a vacuum.
