What effect do different working conditions have on the performance of graphite copper sleeves?

Graphite copper sleeves are sliding bearings with graphite embedded as lubricant on a copper alloy matrix. They have self-lubricating properties and do not require additional oiling. This material combines the advantages of metal alloys and non-metallic anti-friction materials. It has both the high load-bearing capacity of metals and the lubrication properties of anti-friction materials. In actual applications, customer working conditions are different, and the performance of graphite copper sleeves will be affected accordingly under different working conditions.

1. Temperature influence

High temperature environment: The copper matrix in the graphite copper sleeve provides good thermal stability, while the graphite particles enhance its high temperature resistance. In high temperature environments, graphite copper sleeves can maintain good mechanical properties and dimensional stability, and are not prone to thermal deformation or thermal expansion. According to specific working conditions, such as different high temperature conditions such as 200°C, 400°C and 600°C, different high temperature resistant alloy materials can be selected and specially treated to ensure that the graphite copper sleeve can perform optimal performance and life in these environments.

Low temperature environment: Although the performance of graphite copper sleeves in low temperature environment is not as stable as that in high temperature environment, it can still maintain certain mechanical properties and lubrication effect under general low temperature conditions. However, under extreme low temperature conditions, the lubrication and mechanical properties of graphite copper sleeves may be affected to a certain extent, and they need to be used with caution.

2. Load and speed influence

Heavy load: With its excellent load-bearing capacity and wear resistance, graphite copper sleeves can be applied to the production needs of various heavy industries. Under heavy load conditions, graphite copper sleeves can maintain a stable lubrication effect, reduce direct contact and friction between metal parts, and thus reduce wear.

Low speed and heavy load: Graphite copper sleeves perform particularly well under low speed and heavy load conditions. Its self-lubricating properties enable it to maintain a good working condition under such harsh conditions, avoiding equipment damage caused by excessive friction.

High speed conditions: Although graphite copper sleeves have many advantages, they are not suitable for high-speed working environments. Under high-speed operation, the lubrication effect and mechanical properties of graphite copper sleeves may be affected to a certain extent, resulting in increased equipment wear and even failure.

3. Media and environmental impact

Water environment: Graphite-embedded copper sleeves are not recommended for underwater use, because water may affect the lubrication effect of graphite. However, through special material improvements (such as replacing graphite with PTFE), graphite copper sleeves can meet the needs of underwater use.

Corrosive media: Graphite copper sleeves have strong resistance to chemical media such as water and acid, and are not easily corroded or washed away. Therefore, in a corrosive medium environment, graphite copper sleeves can maintain stable performance.

Other environments: Graphite copper sleeves are also suitable for a variety of complex working conditions, including reciprocating or swinging motion. Under these working conditions, graphite copper sleeves can maintain stable lubrication effects and mechanical properties, providing reliable support for equipment.

4. Performance optimization and precautions

Performance optimization:
By selecting high-strength and high-quality copper alloy materials, the performance of graphite copper sleeves can be ensured to be stable and the service life can reach 3 to 5 times that of ordinary copper sleeve products.
According to different working conditions, such as temperature, load, speed, etc., select suitable high-temperature resistant alloy materials and perform special treatments to improve the performance and life of graphite copper sleeves.

Notes:
When using graphite copper sleeves, try to avoid using them under high-speed conditions to avoid malfunctions.
When used underwater or in corrosive media environments, graphite copper sleeves improved with special materials should be selected or other protective measures should be taken.
During the assembly process, care should be taken to keep the surface of the graphite copper sleeve clean and lubricated to avoid foreign matter from mixing in and causing equipment damage.
