2. In the exhaust stage, the liquid ring gradually approaches the hub, and the pumping medium is discharged from the exhaust port along the axial direction.

3. Continuous injection of supplementary liquid to compensate for the liquid taken away by the exhaust gas.

4. In the suction stage, the liquid ring is gradually away from the hub, and the pumping medium is sucked axially from the suction port.

5. Because the impeller is eccentric with respect to the rotating liquid ring, the liquid reciprocates in the space between the blades, —— just like the movement of the piston in the cylinder, —— produces axial suction and compression on the pumping medium.

It operates at 2 vacuum levels

When fitted with an intermediate separator, the left and right parts of the 2BEC pump body can operate at different vacuum levels.As long as the suction pressure difference between the 2 parts (A to B) is less than 80 kPa, A 2BEC can be used as 2 independent vacuum pumps.This feature further enhances the operational flexibility of 2BEC.This flexible solution minimizes energy consumption and footprint in applications that require both vacuum levels.Because the 2BEC was designed with the possibility of long term operation under large differential pressures in mind, its reliability under these operating conditions is not diminished at all.

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.

What Is the Purpose of a Vacuum Pump in an HVAC System?

In an HVAC (Heating, Ventilation, and Air Conditioning) system, a vacuum pump serves a crucial purpose. Here’s a detailed explanation:

The purpose of a vacuum pump in an HVAC system is to remove air and moisture from the refrigerant lines and the system itself. HVAC systems, particularly those that rely on refrigeration, operate under specific pressure and temperature conditions to facilitate the transfer of heat. To ensure optimal performance and efficiency, it is essential to evacuate any non-condensable gases, air, and moisture from the system.

Here are the key reasons why a vacuum pump is used in an HVAC system:

1. Removing Moisture: Moisture can be present within an HVAC system due to various factors, such as system installation, leaks, or improper maintenance. When moisture combines with the refrigerant, it can cause issues like ice formation, reduced system efficiency, and potential damage to system components. A vacuum pump helps remove moisture by creating a low-pressure environment, which causes the moisture to boil and turn into vapor, effectively evacuating it from the system.

2. Eliminating Air and Non-Condensable Gases: Air and non-condensable gases, such as nitrogen or oxygen, can enter an HVAC system during installation, repair, or through leaks. These gases can hinder the refrigeration process, affect heat transfer, and decrease system performance. By using a vacuum pump, technicians can evacuate the air and non-condensable gases, ensuring that the system operates with the designed refrigerant and pressure levels.

3. Preparing for Refrigerant Charging: Prior to charging the HVAC system with refrigerant, it is crucial to create a vacuum to remove any contaminants and ensure the system is clean and ready for optimal refrigerant circulation. By evacuating the system with a vacuum pump, technicians ensure that the refrigerant enters a clean and controlled environment, reducing the risk of system malfunctions and improving overall efficiency.

4. Leak Detection: Vacuum pumps are also used in HVAC systems for leak detection purposes. After evacuating the system, technicians can monitor the pressure to check if it holds steady. A significant drop in pressure indicates the presence of leaks, enabling technicians to identify and repair them before charging the system with refrigerant.

In summary, a vacuum pump plays a vital role in an HVAC system by removing moisture, eliminating air and non-condensable gases, preparing the system for refrigerant charging, and aiding in leak detection. These functions help ensure optimal system performance, energy efficiency, and longevity, while also reducing the risk of system malfunctions and damage.
