About mixer rubber sealing ring
The function of the mixer rubber sealing ring is to prevent medium leakage and maintain the stability of the sealing position. It is usually installed at the sealing position on the agitator shaft and forms close contact with the shaft to prevent the medium from leaking through the sealing position. The rubber sealing ring has a certain deformation ability and resilience, which can adapt to the rotational movement of the mixer shaft and maintain the sealing effect.
When using a mixer rubber seal, how to choose the material, and how to install, maintain, and replace it?
- Material selection: According to the nature of the medium and working conditions, select rubber materials with good chemical resistance, wear resistance, and high-temperature resistance. Common rubber materials include styrene-butadiene rubber (NBR), fluorine rubber (FKM), and silicone rubber (VMQ).
- Correct installation: Make sure the rubber sealing ring is correctly installed on the sealing position of the mixer shaft and forms close contact with the shaft. Be careful to avoid excessive compression or distortion of the rubber sealing ring, which may affect its sealing performance.
- Maintenance and replacement: Check the rubber seal regularly for wear and aging. If problems such as wear, cracks or hardening are found, replace the sealing ring in time to ensure the sealing performance and operational safety of the mixer.
- Lubricant use: According to the recommendations of Linde Polymer factory engineers, use appropriate lubricants to reduce the friction between the rubber seal ring and the shaft and improve the sealing effect.
Next, understand the sealing of the following mixer in general.
Seal of the mixer is a key component to ensure that the mixer does not leak media during operation.
Here are some common mixer seal types
- Rubber Seal: Rubber seal is one of the most common and commonly used methods of sealing a mixer. It is usually made of rubber or elastic material and is installed in a sealed position on the agitator shaft. The rubber sealing ring has good elasticity and corrosion resistance and can effectively prevent medium leakage.
- Mechanical seal: Mechanical seal is a more complex agitator sealing method. It consists of multiple components, including sealing rings, sealing surfaces, springs, etc. The mechanical seal contacts the agitator shaft through the sealing ring and uses the friction and pressure between the sealing surfaces to achieve the sealing effect. Mechanical seals are often used in agitator applications with high pressure, high temperature or special media.
- Agitator cover: In some cases, the sealing of the agitator can be achieved by means of a stirrer cover. The agitator cover is a component that covers the top of the agitator and prevents medium leakage by contacting the sealing edge of the container or tank. The mixer cover is usually equipped with a sealing gasket or rubber sealing ring to ensure good sealing performance.
Agitator rubber sealing ring is one of the common agitator sealing methods and is used to ensure the sealing between the agitator shaft and the sealing position. Rubber seals are typically made of rubber or elastic materials and have good chemical resistance and elasticity.
