Types of Vacuum Pumps
Rotary Piston Vacuum Pump (Oil-Sealed):
Commonly used in vacuum coating, metallurgy, and heat treatment processes.
Operates by using rotating pistons to compress and expand gas.
Requires oil for lubrication and sealing.
Liquid Ring Vacuum Pump:
Widely used due to its reliability and ability to handle wet gases.
Creates a vacuum by rotating a liquid-filled ring.
Ideal for applications like paper production and chemical processing.
Roots Vacuum Pump (Lobe Pump):
Works based on two interlocking rotors that trap and transport gas.
Used in semiconductor manufacturing, freeze-drying, and vacuum furnaces.
Dry Screw Vacuum Pump:
Oil-free and low maintenance.
Suitable for cleanroom environments and sensitive processes.
Used in pharmaceuticals, electronics, and solar panel production.
Applications
Metallurgy and Heat Treatment:
Vacuum pumps aid in creating controlled atmospheres for heat treatment processes.
Improve material properties by preventing oxidation and contamination.
Electronics and Semiconductor Manufacturing:
Vacuum pumps evacuate chambers during semiconductor fabrication.
Essential for maintaining clean environments and preventing particle contamination.
Chemical Processing:
Used in distillation, drying, and solvent recovery.
Ensure efficient separation and purification of chemicals.
Food Industry:
Vacuum packaging extends shelf life by removing air and preventing spoilage.
Freeze-drying preserves food without damaging its structure.
