Product Description

Product Description

Liquid ring vacuum pumps are rotating positive displacement machines providing process vacuum in industrial applications such as chemical, electrical power, environmental, food & beverage processing and packaging, marine, mining, oil & gas, pharmaceutical, pulp & paper, and textiles. Liquid ring vacuum pumps utilize water or other processes compatible liquid as the sealant. The simple operation, with no contacting parts, make liquid ring vacuum pumps a safe and reliable choice for handling dirty and potentially dangerous gas streams. Liquid ring pumps are available in single and dual stage designs and also configured as compressors for even more versatility.

Principle of Operation

The seal liquid forms the ring inside a pump body as the impeller spins creating small chambers for gas to be trapped. The axis of the rotor is eccentric from the body allowing the liquid to almost fill, and then almost empty each rotor chamber during a single revolution, forming the compression of the gas for the pumping action. Vacuum inlet and atmospheric discharge ports provide flow paths for the gas mixture being handled. The heat of compression of the gas is dissipated into the seal liquid, and some of the liquid flows out to discharge. The exhaust gas and residual water discharge is separated from the gas stream and directed to the house exhaust and returned to the pump respectively. Seal fluid is replaced by a constant flow of cooler seal fluid.  

Characteristics

1.Accepts Carryover : Soft solids, moisture, slugs, chemicals and more will not harm the pump. These impurities will simply be washed out through the pump discharge. 
2.Cool & Quiet Operation : The pump runs cool owing to the circulation of the sealing water inside the pump. The operation is relatively quiet – not exceeding 85 dBA. 
3.Constant Operation For Any Vacuum Level :Pump can operate constantly and continuously at any vacuum level – from 29 in. Hg to atmospheric pressure. 

4.Easy Maintenance & Longer Pump Life – Liquid ring vacuum pumps are robust in construction and have only 1 moving part, the rotor, which is mounted on a shaft supported by a set of bearings designed for a long service life of continuous operation. This benefits the user with less wear and simpler, affordable maintenance. 
5.Environmental – Pumps do not require an oil change, filter, oil-pans, condenser or etc. For that reason, plant rooms run clean, free of oil contamination and oil discharges to sewers. 

Technology Behind Vacuum Pump

The design technology behind liquid ring vacuum pumps is advanced to achieve optimum, reliable performance for the rigorous demands of harsh industrial environments. Liquid ring vacuum pumps are an economical and robust solution engineered to meet specific customer requirements. 

Dry air or a dry gas mixture is compressed from vacuum to atmospheric pressure in a liquid ring pump much the same way as it would be in any other displacement type pump, except that there is less of a temperature rise of the gas stream through the pump.Humid air or gas mixtures containing condensable vapor behave quite differently. Some of the vapor that enters a liquid ring pump condenses when it is cooled by the lower temperature seal liquid. The condensate mixes with the seal liquid. Now, it occupies a much-reduced space as contrasted with its former volumetric dimension when it was a component of the inlet gas stream. This volumetric reduction becomes a capacity bonus.

 The only vapor that can be condensed early enough to escape compression contributes to the inlet capacity bonus. In each rotor chamber, the condensation must occur before that chamber passes its inlet port. Any condensation that occurs after the cutoff will not have an effect on pump inlet capacity.
 Liquid ring vacuum pumps can handle large amounts of liquid through its inlet port with a negligible reduction of gas capacity. To maximize the condensation bonus some of the liquid is often sprayed into the inlet piping, upstream of the vacuum pump itself.

How Do Vacuum Pumps Impact the Quality of 3D Printing?

Vacuum pumps play a significant role in improving the quality and performance of 3D printing processes. Here’s a detailed explanation:

3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects by depositing successive layers of material. Vacuum pumps are utilized in various aspects of 3D printing to enhance the overall quality, accuracy, and reliability of printed parts. Here are some key ways in which vacuum pumps impact 3D printing:

1. Material Handling and Filtration: Vacuum pumps are used in 3D printing systems to handle and control the flow of materials. They create the necessary suction force to transport powdered materials, such as polymers or metal powders, from storage containers to the printing chamber. Vacuum systems also assist in filtering and removing unwanted particles or impurities from the material, ensuring the purity and consistency of the feedstock. This helps to prevent clogging or contamination issues during the printing process.

2. Build Plate Adhesion: Proper adhesion of the printed object to the build plate is crucial for achieving dimensional accuracy and preventing warping or detachment during the printing process. Vacuum pumps are employed to create a vacuum environment or suction force that securely holds the build plate and ensures firm adhesion between the first layer of the printed object and the build surface. This promotes stability and minimizes the risk of layer shifting or deformation during the printing process.

3. Material Drying: Many 3D printing materials, such as filament or powdered polymers, can absorb moisture from the surrounding environment. Moisture-contaminated materials can lead to poor print quality, reduced mechanical properties, or defects in the printed parts. Vacuum pumps with integrated drying capabilities can be employed to create a low-pressure environment, effectively removing moisture from the materials before they are used in the printing process. This ensures the dryness and quality of the materials, resulting in improved print outcomes.

4. Resin Handling in Stereolithography (SLA): In SLA 3D printing, a liquid resin is selectively cured using light sources to create the desired object. Vacuum pumps are utilized to facilitate the resin handling process. They can be employed to degas or remove air bubbles from the liquid resin, ensuring a smooth and bubble-free flow during material dispensing. This helps to prevent defects and imperfections caused by trapped air or bubbles in the final printed part.

5. Enclosure Pressure Control: Some 3D printing processes, such as selective laser sintering (SLS) or binder jetting, require the printing chamber to be maintained at a specific pressure or controlled atmosphere. Vacuum pumps are used to create a controlled low-pressure or vacuum environment within the printing chamber, enabling precise pressure regulation and maintaining the desired conditions for optimal printing results. This control over the printing environment helps to prevent oxidation, improve material flow, and enhance the quality and consistency of printed parts.

6. Post-Processing and Cleaning: Vacuum pumps can also aid in post-processing steps and cleaning of 3D printed parts. For instance, in processes like support material removal or surface finishing, vacuum systems can assist in the removal of residual support structures or excess powder from printed objects. They can also be employed in vacuum-based cleaning methods, such as vapor smoothing, to achieve smoother surface finishes and enhance the aesthetics of the printed parts.

7. System Maintenance and Filtration: Vacuum pumps used in 3D printing systems require regular maintenance and proper filtration to ensure their efficient and reliable operation. Effective filtration systems within the vacuum pumps help to remove any contaminants or particles generated during printing, preventing their circulation and potential deposition on the printed parts. This helps to maintain the cleanliness of the printing environment and minimize the risk of defects or impurities in the final printed objects.

In summary, vacuum pumps have a significant impact on the quality of 3D printing. They contribute to material handling and filtration, build plate adhesion, material drying, resin handling in SLA, enclosure pressure control, post-processing and cleaning, as well as system maintenance and filtration. By utilizing vacuum pumps in these critical areas, 3D printing processes can achieve improved accuracy, dimensional stability, material quality, and overall print quality.
