O-shaped rubber seals are a common sealing element that is widely used in a variety of machinery and equipment to achieve fluid and gas sealing. In order to better play the sealing effect of the O-shaped rubber seal ring, a stop ring is often used to assist its work. The following will introduce the type and characteristics of the retaining ring for the O-shaped rubber seal ring in detail.
First, the type of retaining ring
There are three types of retaining rings commonly used for O-shaped rubber seals: semi-circular, eccentric and square.
1. Semi-circular retaining ring: semi-circular retaining ring is a common retaining ring type, which is composed of a semi-circular section and can be closely matched with the O-shaped rubber sealing ring. This kind of stop ring is mainly used to prevent the O-shaped rubber seal ring from axial movement in the work and improve the sealing effect.
2. Eccentric type retainer: eccentric type retainer is a special type of retainer, its cross-section shape is similar to an oval, one of the shaft diameter is small, can be closely matched with the O-shaped rubber sealing ring. The retaining ring is mainly used to prevent the radial runout of the O-shaped rubber seal ring in the work and maintain the stability of the sealing effect.
3. Square stop ring: Square stop ring is a relatively simple type of stop ring, which is composed of a square section and can be closely matched with the O-shaped rubber seal ring. This retaining ring is mainly used to prevent the O-shaped rubber seal ring from axial movement and radial runout in the work, and improve the sealing effect.
Second, the characteristics of the ring
The retaining ring for the O-shaped rubber seal ring has the following characteristics:
1. Good wear resistance: The contact surface of the retaining ring and the O-shaped rubber seal ring has good wear resistance, which can effectively reduce friction and wear and extend the service life of the O-shaped rubber seal ring.
2. Stable size: The size accuracy of the retaining ring is high, which can ensure the matching accuracy with the O-shaped rubber sealing ring and ensure the stability of the sealing effect.
3, a variety of material selection: the ring can be made of a variety of materials, such as stainless steel, carbon steel, plastic, etc., can be selected according to different application scenarios suitable materials.
4. Easy to install: the retaining ring is simple in structure and easy to install, which can reduce installation costs and maintenance costs.
5. Improve the sealing effect: Through the auxiliary role of the retaining ring, the sealing effect of the O-shaped rubber sealing ring can be improved to reduce the risk of leakage.
In short, the type and characteristics of the O-shaped rubber seal ring are different, and the choice of the appropriate ring can effectively improve the working performance and service life of the O-shaped rubber seal ring. In practical applications, appropriate retaining ring types and materials should be selected according to specific application scenarios and needs.
