Copper plating phenomenon happens when refrigeration oil becomes acidic under high temperature. Acidic oil dissolves copper from pipelines, then copper deposits onto steel surfaces of crankshaft and bearing. The deposited copper layer changes bearing clearance.
High exhaust temperature accelerates oil acidification. When exhaust temperature keeps over 130℃ for long time, oil aging speed increases sharply. Regular oil sampling test can detect acid value rise before copper plating appears.
Moisture entering refrigeration system is the primary trigger of oil acidification. System vacuuming before charging refrigerant must reach strict standard, and filter drier should be replaced periodically.
Once copper plating occurs, simple oil change cannot fully solve the problem. The whole refrigeration circuit needs thorough cleaning, and worn bearing components need inspection or replacement.
xtldcool piston refrigeration compressor factory recommends oil sample analysis service for long-running cold storage units. Oil test checks acid value, water content and metal particle concentration.
For low-temperature cold storage piston compressor, liquid flood back must be strictly prevented. Liquid refrigerant dilutes lubricating oil and worsens wear, which further increases oil contamination risk.
FAQ
Q: What is copper plating inside piston refrigeration compressor? A: Copper separates from pipeline and deposits on crankshaft and bearing steel surface.
Q: What main cause triggers copper plating failure? A: Acidified refrigeration oil caused by moisture and high exhaust temperature.
Q: What exhaust temperature accelerates oil aging? A: Continuous running above 130℃ exhaust temperature speeds up oil acidification.
Q: Can copper plating be fixed only by changing refrigeration oil? A: No, full pipeline cleaning and component inspection are required.
Q: How to early detect copper plating risk? A: Take oil sample regularly and test acid value and metal particles.
Q: Does xtldcool provide oil analysis service for piston compressor? A: Yes, oil sample inspection service for cold storage piston compressors.
Q: How to reduce moisture ingress into refrigeration system? A: Complete deep vacuum before refrigerant filling and replace filter drier.
