Introduction of 2BV2 High Pressure Gas Steam Fluid Liquid Water Ring Vacuum Pump
2BV2 High Pressure Gas Steam Fluid Liquid Water Ring Vacuum Pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i.e. 97 % vacuum degree). If the transformer oil is used as the operating liquid, these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i.e. 99 % vacuum degree). So the oil ring vacuum pumps can replace the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect the pump.
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.

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.
How Do You Choose the Right Size Vacuum Pump for a Specific Application?
Choosing the right size vacuum pump for a specific application involves considering several factors to ensure optimal performance and efficiency. Here’s a detailed explanation:
1. Required Vacuum Level: The first consideration is the desired vacuum level for your application. Different applications have varying vacuum level requirements, ranging from low vacuum to high vacuum or even ultra-high vacuum. Determine the specific vacuum level needed, such as microns of mercury (mmHg) or pascals (Pa), and choose a vacuum pump capable of achieving and maintaining that level.
2. Pumping Speed: The pumping speed, also known as the displacement or flow rate, is the volume of gas a vacuum pump can remove from a system per unit of time. It is typically expressed in liters per second (L/s) or cubic feet per minute (CFM). Consider the required pumping speed for your application, which depends on factors such as the volume of the system, the gas load, and the desired evacuation time.
3. Gas Load and Composition: The type and composition of the gas or vapor being pumped play a significant role in selecting the right vacuum pump. Different pumps have varying capabilities and compatibilities with specific gases. Some pumps may be suitable for pumping only non-reactive gases, while others can handle corrosive gases or vapors. Consider the gas load and its potential impact on the pump’s performance and materials of construction.
4. Backing Pump Requirements: In some applications, a vacuum pump may require a backing pump to reach and maintain the desired vacuum level. A backing pump provides a rough vacuum, which is then further processed by the primary vacuum pump. Consider whether your application requires a backing pump and ensure compatibility and proper sizing between the primary pump and the backing pump.
5. System Leakage: Evaluate the potential leakage in your system. If your system has significant leakage, you may need a vacuum pump with a higher pumping speed to compensate for the continuous influx of gas. Additionally, consider the impact of leakage on the required vacuum level and the pump’s ability to maintain it.
6. Power Requirements and Operating Cost: Consider the power requirements of the vacuum pump and ensure that your facility can provide the necessary electrical supply. Additionally, assess the operating cost, including energy consumption and maintenance requirements, to choose a pump that aligns with your budget and operational considerations.
7. Size and Space Constraints: Take into account the physical size of the vacuum pump and whether it can fit within the available space in your facility. Consider factors such as pump dimensions, weight, and the need for any additional accessories or support equipment.
8. Manufacturer’s Recommendations and Expert Advice: Consult the manufacturer’s specifications, guidelines, and recommendations for selecting the right pump for your specific application. Additionally, seek expert advice from vacuum pump specialists or engineers who can provide insights based on their experience and knowledge.
By considering these factors and evaluating the specific requirements of your application, you can select the right size vacuum pump that meets the desired vacuum level, pumping speed, gas compatibility, and other essential criteria. Choosing the appropriate vacuum pump ensures efficient operation, optimal performance, and longevity for your application.
