Rotary Rings

Rotary Rings are a type of rotating seal widely used in various rotating equipment, such as rotary joints, rotary couplings, rotary connectors, etc. Its main function is to prevent liquid or gas leakage and maintain the normal operation of the equipment. In different applications, the material, structure, sealing method, size, etc. of Rotary Rings vary to adapt to different working conditions.

1. Material classification

The materials of Rotary Rings are mainly divided into two categories: metallic and non-metallic.

1. Metal materials

Metal materials mainly include stainless steel, steel, copper, aluminum, etc., which have characteristics of high strength, corrosion resistance, wear resistance, and are suitable for rotary seals in harsh environments such as high temperature, high pressure, and high-speed.

2. Non metallic materials

Non metallic materials mainly include ceramics, silicon carbide, graphite, etc., which have characteristics such as high hardness, high wear resistance, and low friction coefficient. They are suitable for rotary seals under conditions such as low temperature, low pressure, and high speed.

2. Structural classification
The structure of Rotary Rings is mainly divided into three types: unidirectional rotation, bidirectional rotation, and rotational stationary.
1. Unidirectional rotating structure

The Rotary Rings with a unidirectional rotation structure can only rotate in one direction and are suitable for devices with only unidirectional rotation.

2. Bidirectional rotation structure

The Rotary Rings with a bidirectional rotation structure can rotate in two directions, suitable for devices that require bidirectional rotation.

3. Rotating stationary structure

The Rotary Rings with a rotating stationary structure are composed of a rotating ring and a stationary ring. The rotating ring contacts the stationary ring during rotation to achieve sealing, suitable for equipment that requires a rotating stationary seal.

3. Classification of sealing methods

The sealing methods of Rotary Rings are mainly divided into mechanical sealing and liquid sealing.

1. Mechanical seal

Mechanical sealing is achieved through the contact surface between the rotating ring and the stationary ring, which has the characteristics of high reliability, long service life, and simple maintenance. It is suitable for rotary sealing in harsh environments such as high speed, high temperature, and high pressure.

2. Liquid sealing

Liquid sealing is achieved by injecting liquid between the rotating ring and the stationary ring, which has the characteristics of good sealing performance, low friction coefficient, and preventing dry friction. It is suitable for rotary sealing under low speed, low temperature, low pressure, and other conditions.

4. Size classification

The size of Rotary Rings is mainly determined by the equipment requirements, including inner diameter, outer diameter, thickness, shaft diameter, etc.

Rotary Rings, as an important type of rotary seal, are widely used, with different materials, structures, sealing methods, dimensions, etc. to adapt to different working conditions. When selecting Rotary Rings, it is necessary to make the selection based on specific equipment requirements to ensure the normal operation of the equipment.
