How Nash Liquid Ring Vacuum Pumps Work

The Liquid Ring Mechanism

The primary thing of a Nash liquid ring vacuum pump is a rotor positioned eccentrically internal a cylindrical casing. As the rotor spins, a hoop of sealing liquid—commonly water—forms along the internal wall of the casing due to centrifugal pressure. This ring creates a series of compression chambers among the rotor blades.

Compression and Suction Process

Gas enters the pump thru the suction port as the rotor spins. The expanding space between the blades traps the gas, and as rotation continues, the extent reduces, compressing the gas. Once compressed, the fuel is discharged through the hole port. The sealing liquid absorbs warmth from the compression method, aiding in efficient operation with out metal-to-metallic touch.
