An Oil Sealed Rotary High Vacuum Pump is a type of vacuum pump designed to create a stable, high-vacuum environment by removing air and gas from a sealed system. These pumps are widely used in laboratories, pharmaceutical industries, chemical processing, research facilities, and industrial applications, where precise and reliable vacuum conditions are essential.
Unlike dry pumps, this pump uses oil not just for lubrication, but also to seal internal gaps, prevent air leakage, and help the pump achieve deeper vacuum levels.
How Does an Oil Sealed Rotary High Vacuum Pump Work?
The working of an oil sealed rotary vacuum pump is based on the rotary vane principle. Inside the pump, a rotor with sliding vanes rotates within a cylindrical housing. As the rotor spins, the vanes move outward and trap air inside small chambers.
The trapped air is then compressed and pushed out through the exhaust. The vacuum oil acts as a seal between the moving parts, preventing backflow of air and ensuring smooth, efficient operation. The oil also helps lubricate the components and dissipate heat, keeping the pump running reliably for long hours.
Why Oil Is Important in These Pumps
The oil inside a rotary vacuum pump plays a critical role. It:
- Creates a tight seal between moving parts
- Prevents air from leaking back into the system
- Lubricates internal components to reduce wear
- Absorbs and dissipates heat during operation
- Helps achieve a deep, stable vacuum
Maintaining the oil regularly is key to keeping the pump performing efficiently and extending its lifespan.
