Introduction of Water Ring Vacuum Pump

1. Structure

The water ring vacuum pump is mainly composed of the pump body, impeller, shaft, bearings, side cover and bracket, etc. A certain amount of water is contained in the pump body as the operating fluid. The impeller is eccentrically installed in the pump body, surrounded by several radial blades. The pump body is equipped with a suction port and an exhaust port.

2. Working Principle

a. Water ring formation: Before starting the pump, a certain amount of water is injected into the pump first. When the impeller rotates, water is pushed to the periphery of the pump body under the action of centrifugal force, forming a closed water ring.

b. Suction stage: As the impeller rotates, several small cavities are formed in the space between the water ring and the impeller. When the impeller rotates to the suction port position, the volume of the small cavity gradually increases, creating a vacuum and the gas is drawn in through the suction port.

c. Compression stage: As the impellers continue rotating, the volume of the small cavity gradually decreases, and the gas is compressed.

d. Exhaust stage: When the impeller rotates to the exhaust port position, the compressed gas is discharged from the pump through the exhaust port. The discharged gas and water droplets enter the water tank. The gas is separated and discharged, while the water is recycled.

3. Characteristics

Simple structure: The structure of the water ring vacuum pump is relatively simple, with low manufacturing precision requirements and easy processing.

Stable operation: It operates smoothly with low noise and is suitable for long-term continuous operation.

Strong applicability: It can draw gases containing a small amount of liquid or dust and is suitable for various industrial Settings.

Excellent cooling effect: The working water comes into direct contact with the gas, and the compression heat is absorbed by the water, eliminating the need for an additional cooling system.

High safety: The water ring is a flame-retardant medium, suitable for explosion-proof environments.
