Strength Factory Electric Space-Saving 2BV 5110 Two Stage Roots Water Ring Vacuum Pump

2BV liquid ring vacuum pump is mainly composed of pump body, rotor, impeller, suction port, exhaust port and other parts. Among them, the rotor and impeller are usually integrated and are called eccentric rotors. When the rotor rotates, the eccentric rotor drives the impeller to rotate in the pump chamber, forming a liquid ring similar in shape to the pump chamber. The volume of the liquid ring changes as the rotor rotates, thereby completing the process of gas suction, compression and discharge.

2BV liquid ring vacuum pumps are widely used in various industries

Chemical processing: The pump is commonly used in chemical processing plants, where it is essential to handle corrosive and caustic substances. It provides a continuous and reliable vacuum source for processes such as distillation, evaporation, and drying.

Wastewater treatment: The pump is used in wastewater treatment plants to evacuate liquid from settling tanks and other process vessels. It helps in maintaining the required vacuum pressure for efficient operation of the treatment process.

Power generation: In power generation plants, the pump is employed to remove steam and other gases from the condenser unit. It helps in maintaining the vacuum pressure within the condenser, which is essential for efficient heat transfer and power generation.

Semiconductor industry: In the semiconductor industry, the pump is used for the production of electronic components. It provides a vacuum environment for processes such as etching, deposition, and cleaning of wafers.

Food processing: In the food processing industry, the pump is used to evacuate process vessels and lines in applications such as vacuum packaging, freeze-drying, and distillation. It ensures hygienic operation and preserves the quality of food products.

Environmental testing: The pump is also used in environmental testing laboratories for sampling and analysis of air, water, and soil. It provides a controlled vacuum environment for sampling and analysis equipment.

The structure and components of 2BV liquid ring vacuum pump

1. Housing: The pump housing encloses the pumping mechanism and provides a stationary barrier for the moving parts. It is typically made of cast iron or steel.

2. Impeller: The impeller is a rotating component that consists of a series of vanes arranged around a central hub. It is connected to the motor shaft and rotates within the housing.

3. Liquid Ring: A liquid ring is formed by the impeller vanes as they rotate. The liquid (typically water or oil) entrained within the vanes helps to seal the gaps between the impeller and housing, creating a vacuum seal.

4. Motor: The motor is the driving mechanism that rotates the impeller. It is connected to the impeller shaft and provides the required torque to rotate the impeller within the housing.

5. Gasket: A gasket is used to seal the connection between the motor and housing, preventing leakage of the working fluid.

6. Exhaust: The exhaust port directs the vacuum-formed gases and any entrained liquid out of the pump. It typically leads to a collection system or other equipment where the gases and liquids are further processed or exhausted to the atmosphere.

7. Bearing and Lubrication System: The bearing system supports the rotating shaft and provides stability during operation. It also includes a lubrication system that supplies lubricant to the bearings to reduce wear and enhance durability.

8. Control Systems: Optional control systems may be included to monitor pump operation, control vacuum levels, or provide automatic shutdown features for safety or operational efficiency.
