概要: The manufacturer of liquid-ring vacuum pumps states that these pumps are equipped with an axial-force motor rotor featuring fixed blades. During operation, water (or liquid) is thrown onto the stator wall of the motor, forming a liquid ring that works in tandem with the motor stator. Together, the liquid ring and the rotor blades constitute a variable-capacity rotary vacuum pump with adjustable inlet capacity. The manufacturer further notes that liquid-ring vacuum pumps have a compact structure and relatively high rotational speeds; they can typically be directly connected to a motor without requiring any speed-reducing equipment. As a result, these pumps feature small overall dimensions, large drainage capacities, and a minimal footprint. Moreover, the compression of air within the pump chamber is largely isothermal, meaning the temperature of the compressed air remains virtually unchanged throughout the process. Since there are no metal-to-metal friction surfaces inside the pump cavity, lubrication is unnecessary, minimizing wear and tear. Additionally, the exhaust valve ensures immediate sealing between the rotating components and the stationary housing. Consequently, liquid-ring vacuum pumps offer advantages such as uniform suction, stable and reliable operation, and ease of use and maintenance. These pumps are widely used in various industries, including coal mining, chemical plants, pharmaceutical manufacturing, mining, paper production, food processing, brewing, decorative building materials, plastics, metallurgy, and electrical equipment manufacturing. Furthermore, liquid-ring vacuum pumps boast high pumping speeds and can generally be directly coupled to motors without the need for speed-reducing devices. Thus, liquid-ring vacuum

The manufacturer of liquid-ring vacuum pumps states that these pumps are equipped with an axial-force motor rotor featuring fixed blades. During operation, water (or liquid) is primarily flung onto the stator wall of the motor, where it forms a liquid ring that works in tandem with the motor stator. Subsequently, the liquid ring and the blades of the motor rotor together constitute a variable-capacity rotary vacuum pump with adjustable inlet capacity.

The manufacturer of liquid-ring vacuum pumps states that these pumps feature a compact structure and relatively high rotational speed, allowing them to be directly connected to the motor without the need for a reduction gear. As a result, they have a small overall footprint, large pumping capacity, and occupy minimal space. Moreover, the compression of air in these pumps is largely isothermal, meaning the temperature of the compressed air remains virtually unchanged throughout the process. Since there are no metal surfaces in the pump chamber subject to friction, lubrication is not required, minimizing wear and tear. The exhaust valve can immediately achieve a tight seal between the rotating parts and the stationary housing. Consequently, liquid-ring vacuum pumps offer advantages such as uniform suction, stable and reliable operation, and ease of use and maintenance. Meanwhile, liquid-ring vacuum pumps are widely used in industries including coal mining, chemical plants, pharmaceutical manufacturing, mining, paper production, food processing, brewing, decorative building materials, plastics, metallurgy, and electrical equipment. Additionally, due to their high pumping speed, liquid-ring vacuum pumps can typically be directly coupled to motors without requiring a reduction gear. Therefore, these pumps boast a small overall size, large displacement, and compact footprint. Furthermore, the compressed gas undergoes essentially isothermal compression, meaning its temperature changes very little during the compression process.

The manufacturer of liquid-ring vacuum pumps states that, since there are no metal friction surfaces inside the pump chamber, liquid-ring vacuum pumps do not require lubrication and experience very little wear. The seal between the rotating and stationary parts can be achieved directly through a water seal. Liquid-ring vacuum pumps offer uniform suction, stable and reliable operation, simple operation, and convenient maintenance. Overall, they feature a compact structure, balanced and reliable performance, and steady flow rates. In chemical production, these pumps are often used to convey or pump flammable, explosive, and corrosive gases. However, because the impeller stirs the liquid, liquid-ring vacuum pumps lose a significant amount of energy, resulting in relatively low efficiency. Nevertheless, they do have certain drawbacks: their efficiency is generally around 30%, though some higher-quality models can reach up to 50%. Another limitation is the low vacuum degree achievable by liquid-ring pumps—this is not only constrained by the pump’s design but more importantly by the saturation vapor pressure of the working fluid. When water is used as the working medium, the ultimate vacuum level can only reach 2,000 to 4,000 Pa; when oil is used as the working fluid, the maximum vacuum can attain about 130 Pa. In short, since gas compression in liquid-ring vacuum pumps occurs under isothermal conditions, they can effectively extract flammable and explosive gases. Moreover, due to the absence of exhaust valves and friction surfaces, these pumps can handle dusty gases, condensable gases, and gas-water mixtures. Thanks to these outstanding features, liquid-ring vacuum pumps are widely employed in various industrial applications.
