Material issues of the flow-blocking ring in the oil-free packing box of reciprocating compressors
Thread Content
Can a copper material be used for the flow-blocking ring in a high-pressure, oil-free environment?
It is best to replace the components according to the original design; if any issues arise, the cause can be sought in other areas. It’s best to upload two pictures to facilitate discussion. For reference.
In a high-pressure, oil-free environment, using copper for the flow-blocking ring may not be the best choice. Copper is prone to wear in the absence of lubrication; especially in high-pressure environments, its wear resistance and corrosion resistance may be insufficient. Given the high-pressure and oil-free operating conditions, cemented carbide, ceramics, or special synthetic materials are more recommended, as they offer better resistance to high temperatures, corrosion, and wear. .
