Structure:
 

1. The only rotating part of 2BEA/2BEC —- impeller makes the working fluid form hydraulic pressure in the oval pump body by rotating.At this time, the working fluid plays 3 roles of sealing medium, compression medium and cooling medium at the same time, without wear and lubrication.

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 Affect the Performance of Vacuum Chambers?

When it comes to the performance of vacuum chambers, vacuum pumps play a critical role. Here’s a detailed explanation:

Vacuum chambers are enclosed spaces designed to create and maintain a low-pressure environment. They are used in various industries and scientific applications, such as manufacturing, research, and material processing. Vacuum pumps are used to evacuate air and other gases from the chamber, creating a vacuum or low-pressure condition. The performance of vacuum chambers is directly influenced by the characteristics and operation of the vacuum pumps used.

Here are some key ways in which vacuum pumps affect the performance of vacuum chambers:

1. Achieving and Maintaining Vacuum Levels: The primary function of vacuum pumps is to create and maintain the desired vacuum level within the chamber. Vacuum pumps remove air and other gases, reducing the pressure inside the chamber. The efficiency and capacity of the vacuum pump determine how quickly the desired vacuum level is achieved and how well it is maintained. High-performance vacuum pumps can rapidly evacuate the chamber and maintain the desired vacuum level even when there are gas leaks or continuous gas production within the chamber.

2. Pumping Speed: The pumping speed of a vacuum pump refers to the volume of gas it can remove from the chamber per unit of time. The pumping speed affects the rate at which the chamber can be evacuated and the time required to achieve the desired vacuum level. A higher pumping speed allows for faster evacuation and shorter cycle times, improving the overall efficiency of the vacuum chamber.

3. Ultimate Vacuum Level: The ultimate vacuum level is the lowest pressure that can be achieved in the chamber. It depends on the design and performance of the vacuum pump. Higher-quality vacuum pumps can achieve lower ultimate vacuum levels, which are important for applications requiring higher levels of vacuum or for processes that are sensitive to residual gases.

4. Leak Detection and Gas Removal: Vacuum pumps can also assist in leak detection and gas removal within the chamber. By continuously evacuating the chamber, any leaks or gas ingress can be identified and addressed promptly. This ensures that the chamber maintains the desired vacuum level and minimizes the presence of contaminants or unwanted gases.

5. Contamination Control: Some vacuum pumps, such as oil-sealed pumps, use lubricating fluids that can introduce contaminants into the chamber. These contaminants may be undesirable for certain applications, such as semiconductor manufacturing or research. Therefore, the choice of vacuum pump and its potential for introducing contaminants should be considered to maintain the required cleanliness and purity of the vacuum chamber.

6. Noise and Vibrations: Vacuum pumps can generate noise and vibrations during operation, which can impact the performance and usability of the vacuum chamber. Excessive noise or vibrations can interfere with delicate experiments, affect the accuracy of measurements, or cause mechanical stress on the chamber components. Selecting vacuum pumps with low noise and vibration levels is important for maintaining optimal chamber performance.

It’s important to note that the specific requirements and performance factors of a vacuum chamber can vary depending on the application. Different types of vacuum pumps, such as rotary vane pumps, dry pumps, or turbomolecular pumps, offer varying capabilities and features that cater to specific needs. The choice of vacuum pump should consider factors such as the desired vacuum level, pumping speed, ultimate vacuum, contamination control, noise and vibration levels, and compatibility with the chamber materials and gases used.

In summary, vacuum pumps have a significant impact on the performance of vacuum chambers. They enable the creation and maintenance of the desired vacuum level, affect the pumping speed and ultimate vacuum achieved, assist in leak detection and gas removal, and influence contamination control. Careful consideration of the vacuum pump selection ensures optimal chamber performance for various applications.
