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 Assist in Freeze-Drying Processes?

Freeze-drying, also known as lyophilization, is a dehydration technique used in various industries, including pharmaceutical manufacturing. Vacuum pumps play a crucial role in facilitating freeze-drying processes. Here’s a detailed explanation:

During freeze-drying, vacuum pumps assist in the removal of water or solvents from pharmaceutical products while preserving their structure and integrity. The freeze-drying process involves three main stages: freezing, primary drying (sublimation), and secondary drying (desorption).

1. Freezing: In the first stage, the pharmaceutical product is frozen to a solid state. Freezing is typically achieved by lowering the temperature of the product below its freezing point. The frozen product is then placed in a vacuum chamber.

2. Primary Drying (Sublimation): Once the product is frozen, the vacuum pump creates a low-pressure environment within the chamber. By reducing the pressure, the boiling point of water or solvents present in the frozen product is lowered, allowing them to transition directly from the solid phase to the vapor phase through a process called sublimation. Sublimation bypasses the liquid phase, preventing potential damage to the product’s structure.

The vacuum pump maintains a low-pressure environment by continuously removing the water vapor or solvent vapor generated during sublimation. The vapor is drawn out of the chamber, leaving behind the freeze-dried product. This process preserves the product’s original form, texture, and biological activity.

3. Secondary Drying (Desorption): After the majority of the water or solvents have been removed through sublimation, the freeze-dried product may still contain residual moisture or solvents. In the secondary drying stage, the vacuum pump continues to apply vacuum to the chamber, but at a higher temperature. The purpose of this stage is to remove the remaining moisture or solvents through evaporation.

The vacuum pump maintains the low-pressure environment, allowing the residual moisture or solvents to evaporate at a lower temperature than under atmospheric pressure. This prevents potential thermal degradation of the product. Secondary drying further enhances the stability and shelf life of the freeze-dried pharmaceutical product.

By creating and maintaining a low-pressure environment, vacuum pumps enable efficient and controlled sublimation and desorption during the freeze-drying process. They facilitate the removal of water or solvents while minimizing the potential damage to the product’s structure and preserving its quality. Vacuum pumps also contribute to the overall speed and efficiency of the freeze-drying process by continuously removing the vapor generated during sublimation and evaporation. The precise control provided by vacuum pumps ensures the production of stable and high-quality freeze-dried pharmaceutical products.

What Is a Vacuum Pump, and How Does It Work?

A vacuum pump is a mechanical device used to create and maintain a vacuum or low-pressure environment within a closed system. Here’s a detailed explanation:

A vacuum pump operates on the principle of removing gas molecules from a sealed chamber, reducing the pressure inside the chamber to create a vacuum. The pump accomplishes this through various mechanisms and techniques, depending on the specific type of vacuum pump. Here are the basic steps involved in the operation of a vacuum pump:

1. Sealed Chamber:

The vacuum pump is connected to a sealed chamber or system from which air or gas molecules need to be evacuated. The chamber can be a container, a pipeline, or any other enclosed space.

2. Inlet and Outlet:

The vacuum pump has an inlet and an outlet. The inlet is connected to the sealed chamber, while the outlet may be vented to the atmosphere or connected to a collection system to capture or release the evacuated gas.

3. Mechanical Action:

The vacuum pump creates a mechanical action that removes gas molecules from the chamber. Different types of vacuum pumps use various mechanisms for this purpose:

– Positive Displacement Pumps: These pumps physically trap gas molecules and remove them from the chamber. Examples include rotary vane pumps, piston pumps, and diaphragm pumps.

– Momentum Transfer Pumps: These pumps use high-speed jets or rotating blades to transfer momentum to gas molecules, pushing them out of the chamber. Examples include turbomolecular pumps and diffusion pumps.

– Entrapment Pumps: These pumps capture gas molecules by adsorbing or condensing them on surfaces or in materials within the pump. Cryogenic pumps and ion pumps are examples of entrainment pumps.

4. Gas Evacuation:

As the vacuum pump operates, it creates a pressure differential between the chamber and the pump. This pressure differential causes gas molecules to move from the chamber to the pump’s inlet.

5. Exhaust or Collection:

Once the gas molecules are removed from the chamber, they are either exhausted into the atmosphere or collected and processed further, depending on the specific application.

6. Pressure Control:

Vacuum pumps often incorporate pressure control mechanisms to maintain the desired level of vacuum within the chamber. These mechanisms can include valves, regulators, or feedback systems that adjust the pump’s operation to achieve the desired pressure range.

7. Monitoring and Safety:

Vacuum pump systems may include sensors, gauges, or indicators to monitor the pressure levels, temperature, or other parameters. Safety features such as pressure relief valves or interlocks may also be included to protect the system and operators from overpressure or other hazardous conditions.

It’s important to note that different types of vacuum pumps have varying levels of vacuum they can achieve and are suitable for different pressure ranges and applications. The choice of vacuum pump depends on factors such as the required vacuum level, gas composition, pumping speed, and the specific application’s requirements.

In summary, a vacuum pump is a device that removes gas molecules from a sealed chamber, creating a vacuum or low-pressure environment. The pump accomplishes this through mechanical actions, such as positive displacement, momentum transfer, or entrapment. By creating a pressure differential, the pump evacuates gas from the chamber, and the gas is either exhausted or collected. Vacuum pumps play a crucial role in various industries, including manufacturing, research, and scientific applications.
