Products Description
A customized rotating PTFE glyd ring is a seal used for rotating or oscillating moving parts, usually made of polytetrafluoroethylene (PTFE) material.
The main function of the seal is to prevent liquid, gas, or other media from leaking between rotating parts while reducing friction and wear.
design characteristics
- Low friction: PTFE material has a low friction coefficient, which can reduce the energy consumption and heat generation of rotating parts.
- High wear resistance: By adding metal or inorganic fillers, PTFE's wear resistance and mechanical strength can significantly improve.
- High temperature and chemical corrosion resistance: PTFE can work for a long time within a certain temperature range (-45°C to +200°C) and is almost not corroded by chemical media.
- Self-lubricating property: PTFE has good self-lubricating properties, which reduces the dependence on lubricants and the system's maintenance cost.
- Bidirectional sealing ability: Customized rotating PTFE glyd ring can withstand pressure from one or both sides and is suitable for complex motion environments.
Sealing principle
The rotating glyd ring is composed of a sealing ring made of polytetrafluoroethylene and additives, and the O-ring acts as an elastic force-applying element.
Depending on the seal profile, the contact surface has one or two continuous machined grooves with a concave shape on the back of the O-ring. This increases the contact surface and prevents the seal from rotating with the surfaces rotating together.
Applications
Rotating PTFE Glyd Ring can be used in a variety of industries, including:
1. Chemical Industry: Used in pumps, reactors, and pressure vessels to prevent leaks of hazardous chemicals.
2. Food Processing: Essential in machinery such as mixers and presses to ensure fluid integrity and safety.
3. Mechanical Engineering: Used in hydraulic cylinders, pneumatic systems, and various machine tools.
