Ring Vacuum Pump

Here is the improved and rewritten English version of your content, with a total of over 500 characters and presented in a more natural, human-like tone: --- **Overview** The 2BV series water ring vacuum pumps are energy-efficient models developed by our company after extensive market research and analysis, combining many years of scientific research, production experience, and international advanced technology. As a new generation of product, the 2BV series offers excellent performance and advantages, outperforming traditional models like SK and 2SK series pumps in terms of pumping efficiency and reliability. **Purpose** These pumps are primarily designed for the suction of gas that is free from solid particles and insoluble in water. They are widely used in various industries such as vessel evacuation, condenser evacuation, water extraction systems, plastic molding (degassing), food processing, vacuum distillation, hospital sterilization, central suction systems, and beverage can production lines. Additionally, they find applications in petroleum, chemical, pharmaceutical, power, metallurgy, and environmental protection sectors. **Working Principle** The 2BV series pump features a coaxial direct-coupled design, where the pump body is directly mounted on the motor. The rotation of the impeller is driven by the motor shaft, causing the working fluid to form a liquid ring inside the oval pump body. This working fluid acts as a sealing, compression, and cooling medium simultaneously, eliminating the need for lubrication and reducing wear. As the impeller rotates eccentrically within the liquid ring, the liquid moves back and forth between the blades, similar to the motion of a piston in an air cylinder, resulting in gas suction and compression. During the suction phase, the liquid ring moves away from the hub, drawing in gas through the inlet port. In the exhaust stage, the liquid ring approaches the hub, expelling the gas through the outlet port to create a vacuum. An external liquid pipeline continuously supplies fresh liquid to compensate for the loss caused by the discharged gas. **Working Conditions** - Gas flow range: 27–500 m³/h - Pressure range: 33 hPa – 1013 hPa - Temperature range: Optimal suction gas temperature -10°C to 40°C; Working fluid temperature 0°C to 35°C - Allowed medium: Gas that is water-insoluble and free from solid particles
