Working principle of water ring vacuum pump / liquid ring vacuum pump
The water-ring vacuum pump is a kind of coarse vacuum pump. The limit vacuum it can obtain is 2000-4000 Pa. The series air ejector can reach 270-670 Pa. Water ring pump can also be used as compressor, called water ring compressor, is a low-pressure compressor, its pressure range is 1-2X105 Pa meter pressure.
Water-ring vacuum pumps were originally used as self-suction pumps, and then gradually used in petroleum, chemical, mechanical, mining, light industry, medicine and food and many other industrial sectors. In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing, water ring pump has been widely used. Due to the rapid development of vacuum application technology, water ring pump has been paid much attention in obtaining coarse vacuum. Because the gas compression in the water ring pump is isothermal, it can extract flammable and explosive gases, in addition, it can also extract dust, water-bearing gases, so the application of water ring pump is increasing.
The pump body contains proper amount of water as working fluid. When the impeller rotates clockwise in the diagram, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring which is approximately equal to the thickness of the pump cavity. The inner surface of the lower part of the water ring is exactly tangent to the hub of the impeller, and the upper inner surface of the water ring is just at the tip of the blade (in fact, the blade has a certain insertion depth in the water ring). At this time, a crescent space is formed between the hub and the water ring of the impeller, which is divided into several small cavities equal to the number of blades. If the lower zero of the impeller is taken as the starting point, the area of the small cavity increases from small to large when the impeller rotates 180 degrees, and is connected with the suction port on the end face. At this time, the gas is sucked in, and the small cavity is isolated from the suction port when the suction is finished. When the mouth is connected, the gas is discharged out of the pump.

Are There Noise Considerations When Using Piston Vacuum Pumps?
Yes, there are noise considerations to take into account when using piston vacuum pumps. Here’s a detailed explanation:
– Piston vacuum pumps can generate noise during their operation, which is important to consider, especially in environments where noise levels need to be minimized.
– The noise produced by piston vacuum pumps is primarily caused by mechanical vibrations and the movement of internal components.
– The noise level can vary depending on factors such as the design and construction of the pump, the speed of operation, and the load conditions.
– Excessive noise from piston vacuum pumps can have several implications:
– Occupational Health and Safety: High noise levels can pose a risk to the health and safety of operators and personnel working in the vicinity of the pump. Prolonged exposure to loud noise can lead to hearing damage and other related health issues.
– Environmental Impact: In certain settings, such as residential areas or noise-sensitive locations, excessive noise from piston vacuum pumps may result in noise pollution and non-compliance with local noise regulations.
– Equipment Interference: Noise generated by the pump can interfere with the operation of nearby sensitive equipment, such as electronic devices or precision instruments, potentially affecting their performance.
– To mitigate the noise produced by piston vacuum pumps, several measures can be taken:
– Enclosures and Sound Insulation: Installing acoustic enclosures or sound-insulating materials around the pump can help contain and reduce the noise. These enclosures are designed to absorb or block the sound waves generated by the pump.
– Vibration Isolation: Using vibration isolation mounts or pads can help minimize the transmission of vibrations from the pump to surrounding structures, reducing the noise level.
– Maintenance and Lubrication: Regular maintenance, including lubrication of moving parts, can help reduce friction and mechanical noise generated by the pump.
– Operating Conditions: Adjusting the operating conditions of the pump, such as speed and load, within the manufacturer’s specified limits can help optimize performance and minimize noise generation.
– Location and Placement: Proper positioning and placement of the pump, considering factors such as distance from occupied areas or sensitive equipment, can help minimize the impact of noise.
– It is important to consult the manufacturer’s guidelines and recommendations regarding noise levels and any specific measures to mitigate noise for a particular piston vacuum pump model.
– Compliance with local regulations and standards regarding noise emissions should also be considered and adhered to.
In summary, noise considerations are important when using piston vacuum pumps to ensure the health and safety of personnel, minimize environmental impact, and prevent interference with other equipment. Measures such as enclosures, vibration isolation, maintenance, and proper operating conditions can help mitigate the noise generated by these pumps.
What Are the Differences Between Single-Stage and Two-Stage Piston Vacuum Pumps?
Single-stage and two-stage piston vacuum pumps are two common types of pumps used for creating a vacuum. Here’s a detailed explanation of their differences:
1. Number of Stages:
– The primary difference between single-stage and two-stage piston vacuum pumps lies in the number of stages or steps involved in the compression process.
– A single-stage pump has a single piston that compresses the gas in one stroke.
– In contrast, a two-stage pump consists of two pistons arranged in series, allowing the gas to be compressed in two stages.
2. Compression Ratio:
– Single-Stage: In a single-stage piston vacuum pump, the compression ratio is limited to the single stroke of the piston. This means that the pump can achieve a compression ratio of approximately 10:1.
– Two-Stage: In a two-stage piston vacuum pump, the compression ratio is significantly higher. The first stage compresses the gas, and then it passes through an intermediate chamber before entering the second stage for further compression. This allows for a higher compression ratio, typically around 100:1.
3. Vacuum Level:
– Single-Stage: Single-stage piston vacuum pumps are generally suitable for applications that require moderate vacuum levels.
– They can achieve vacuum levels up to approximately 10-3 Torr (millitorr) or in the low micron range (10-6 Torr).
– Two-Stage: Two-stage piston vacuum pumps are capable of reaching deeper vacuum levels compared to single-stage pumps.
– They can achieve vacuum levels in the high vacuum range, typically down to 10-6 Torr or even lower, making them suitable for applications that require a more extensive vacuum.
4. Pumping Speed:
– Single-Stage: Single-stage pumps generally have a higher pumping speed or evacuation rate compared to two-stage pumps.
– This means that single-stage pumps can evacuate a larger volume of gas per unit of time, making them suitable for applications that require faster evacuation.
– Two-Stage: Two-stage pumps have a lower pumping speed compared to single-stage pumps.
– While they may have a slower evacuation rate, they compensate for it by achieving deeper vacuum levels.
5. Applications:
– Single-Stage: Single-stage piston vacuum pumps are commonly used in applications that require moderate vacuum levels and higher pumping speeds.
– They are suitable for laboratory use, vacuum packaging, HVAC systems, and various industrial processes.
– Two-Stage: Two-stage piston vacuum pumps are well-suited for applications that require deeper vacuum levels.
– They are commonly used in scientific research, semiconductor manufacturing, analytical instruments, and other processes that demand high vacuum conditions.
6. Size and Complexity:
– Single-Stage: Single-stage pumps are generally more compact and simpler in design compared to two-stage pumps.
– They have fewer components, making them easier to install, operate, and maintain.
– Two-Stage: Two-stage pumps are relatively larger and more complex in design due to the additional components required for the two-stage compression process.
– They may require more maintenance and expertise for operation and servicing.
In summary, the main differences between single-stage and two-stage piston vacuum pumps lie in the number of stages, compression ratio, achievable vacuum levels, pumping speed, applications, and size/complexity. Selecting the appropriate pump depends on the desired vacuum level, pumping speed requirements, and specific application needs.
