When the compressors work, the maximum pressure is 0.26MPa(abs). And the higher of discharge pressure, the larger of the power of the compressors. So it is necessary that the data of the discharge pressure is provided to choose the proper motor.
2BV series water ring vacuum pumps and compressors will replace the SK and 2SK series water ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.

2BV2-Ex,2BV6 series water ring vacuum pumps and compressors are mainly used for pumping the explosive gases or work in the flammable and explosive environment. The technical parameter of each type is the same as the corresponding type of the 2BV2 or 2BV5 series products.
2BV series stainless steel pumps can be used under the conditions with higher requirements for the corrosive-proof or the lustration.

According to the working situation, the material of all the parts where the liquid flows (i.e. pump casing, pump cover, port plate, impeller)are made of various stainless steel as bellow:

The material of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are used the John Crane products and the seals material is optional for FPM or PTFE.

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.
