Working principle

Suction vacuum is realized by a direct-connected rotary vane vacuum pump. The vacuum pump is automatically controlled by the start button and the electric contact vacuum gauge. In the initial state, the start button starts the vacuum pump, and the gas in the mixing tank is sucked out by the vacuum pump, so that negative pressure is formed in the tank. The vacuum degree in the tank is displayed and controlled by the electric contact vacuum gauge. When the specified upper limit is reached, the vacuum pump will automatically stop running. There is a vacuum liquid dust filter (VAF-32) and a one-way valve between the vacuum pump and the mixing barrel. The function of the filter is to prevent impurities from entering the vacuum pump, and the one-way valve is to prevent the air from returning when the vacuum pump stops working.

Can Rotary Vane Pumps Handle Corrosive Gases or Vapors?

Rotary vane pumps are generally not suitable for handling corrosive gases or vapors due to their construction and materials. Here’s a detailed explanation:

– Construction: Rotary vane pumps consist of a rotor with vanes that slide in and out of slots within the rotor. The pumping chamber is sealed by these vanes, creating the necessary vacuum or pressure. The internal components of rotary vane pumps are typically made of materials such as cast iron, steel, or aluminum. While these materials are suitable for many applications, they may not withstand the corrosive effects of certain gases or vapors.

– Corrosion Concerns: Corrosive gases or vapors can react with the internal components of the pump, leading to material degradation, erosion, or chemical reactions. This can result in the formation of deposits, pitting, or damage to the pump’s surfaces. Corrosion can compromise the pump’s performance, efficiency, and longevity. In some cases, it can also introduce contaminants into the pumped medium, affecting the quality of the process or downstream equipment.

– Material Compatibility: The compatibility of the pump’s internal materials with the corrosive gases or vapors is a critical consideration. Many corrosive gases or vapors require specialized materials such as stainless steel, Hastelloy, or other corrosion-resistant alloys to withstand their effects. Rotary vane pumps typically do not have internal components made from these materials, making them unsuitable for handling corrosive substances.

– Alternative Solutions: If corrosive gases or vapors need to be handled, alternative pump technologies specifically designed for such applications may be more appropriate. For example, chemical-resistant pumps made from materials compatible with the corrosive substances, such as diaphragm pumps, magnetic drive pumps, or certain types of centrifugal pumps, are commonly used. These pumps incorporate corrosion-resistant materials and specialized sealing mechanisms to ensure safe and reliable operation.

– Protective Measures: In some cases, it may be possible to use rotary vane pumps for applications involving mildly corrosive gases or vapors by implementing protective measures. This can include installing chemical traps or filters in the pump system to remove or neutralize corrosive substances before they reach the pump. However, the effectiveness and feasibility of such measures depend on the specific application and the level of corrosion resistance required.

It’s important to consult with pump manufacturers or industry experts to determine the most suitable pump technology for handling corrosive gases or vapors. They can provide guidance on selecting the appropriate pump materials and design to ensure safe and efficient operation in corrosive environments.

Overall, while rotary vane pumps offer many advantages in various applications, they are generally not recommended for handling corrosive gases or vapors due to the potential for material damage and performance degradation. Using pumps specifically designed for corrosive applications is crucial to maintain operational integrity and prevent costly failures.

How Does a Rotary Vane Pump Work?

A rotary vane pump is a type of positive displacement pump commonly used for creating vacuum or low-pressure environments. Here’s a detailed explanation of how a rotary vane pump works:

– Basic Principle: A rotary vane pump operates based on the principle of positive displacement. It uses a rotating mechanism with sliding vanes to create a continuous pumping action.

– Construction: A typical rotary vane pump consists of several key components:

– Rotor: The rotor is the central rotating element of the pump. It is typically offset from the center of the pump chamber and is connected to a drive mechanism, such as an electric motor.

– Vanes: The vanes are sliding elements that are inserted into radial slots in the rotor. They can be made of various materials, such as carbon, graphite, or synthetic materials, and are in constant contact with the pump chamber walls.

– Stator: The stator is the stationary part of the pump. It forms the pump chamber and is typically cylindrical in shape with an eccentric bore that accommodates the rotor.

– Inlet and Outlet Ports: The pump has separate inlet and outlet ports. The inlet allows the entry of gas or fluid into the pump, while the outlet facilitates the discharge of the pumped medium.

– Operation:

1. Starting Position: Initially, the rotor is positioned eccentrically within the stator, creating spaces, or cells, between the rotor vanes and the stator walls.

2. Intake Stroke: As the rotor rotates, one vane enters the intake port. This creates an expanding cell, leading to a decrease in pressure within the cell. This pressure drop causes gas or fluid to enter the pump through the inlet port and fill the expanding cell.

3. Compression Stroke: As the rotor continues to rotate, the vane moves along the stator wall, reducing the size of the cell. This compression action compresses the gas or fluid within the cell, increasing its pressure.

4. Discharge Stroke: The compressed gas or fluid is then pushed towards the outlet port as the vane moves further along the stator wall. This leads to the expulsion of the medium from the pump through the outlet port.

5. Repeat Process: The above steps are repeated continuously as the rotor continues to rotate, creating a continuous pumping action.

– Sealing and Lubrication: To ensure efficient operation and prevent leakage, rotary vane pumps require proper sealing and lubrication. The vanes slide against the stator walls, forming a seal to minimize backflow and leakage. Often, a small amount of oil or lubricant is introduced into the pump chamber to provide lubrication and maintain the seal between the vanes and the stator walls.

– Applications: Rotary vane pumps are commonly used in a variety of applications, including HVAC systems, vacuum packaging, laboratory equipment, automotive industry, and industrial processes that require vacuum or low-pressure conditions.

– It’s important to note that the performance of a rotary vane pump can be influenced by factors such as the speed of rotation, the number and dimensions of vanes, the quality of sealing, and the type of lubrication used.

In summary, a rotary vane pump operates based on the principle of positive displacement. It utilizes a rotating rotor with sliding vanes inside a stationary stator to create a continuous pumping action. The pump’s design allows for the intake, compression, and discharge of gas or fluid, making it suitable for various applications requiring vacuum or low-pressure environments.
