Thursday February-16 2023 11:57:34
Rotary vibrating screen sealing ring is mainly used between the grid and the dust cover, has a great help to the screen channel sealing, not only can prevent the collapse of dust into and material leakage, but also can play a role in protecting the screen frame, so how to correctly choose the rotary vibrating screen sealing ring? Xiaobian will introduce you next:
Sealing ring classification
The commonly used sealing rings can be divided into V-shaped and U-shaped, and the commonly used materials are silicone sealing rings, rubber sealing rings and polyurethane sealing rings. The properties, advantages and disadvantages of each material are different as shown below.
1, polyurethane sealing ring
Polyurethane sealing ring is mainly used for special materials, but the polyurethane sealing ring is commonly used for rotating vibrating screen equipment, and it is generally only selected when the user has special requirements.
Advantages: oil resistance, corrosion resistance and high temperature resistance
Disadvantages: wear resistance is not as good as rubber seal ring and high cost.
2. Silica gel sealing ring
Mainly used for materials with special properties, such as high temperature, corrosion, oily substances.
Disadvantages: Relatively high cost, not suitable for most concentrated solvents, concentrated acids, oils and dilute sodium hydroxide.
Advantages: Some specially formulated silicone rubber can withstand extremely low temperatures, such as cryogenic seals. Chemical stability, high adsorption performance, strong thermal stability, relatively high mechanical strength.
3. Rubber sealing ring
Is a rotary vibrating screen commonly used sealing ring accessories, there is no special requirements under normal circumstances. Standard sealers are equipped with rubber seals.
Disadvantages: poor corrosion resistance, high temperature resistance, oil resistance.
Advantages: low cost, wear resistance, long service life, stable performance.
The three sealing rings have different characteristics. When purchasing the sealing ring, the appropriate sealing ring should be selected according to the material characteristics, which can prolong the service life of the sealing ring and effectively reduce production costs.
