Internal corrosion causes 27% of hidden metal particle contamination and slow failure, xiteliduo Refrigeration Compressors analyzes corrosion sources and prevention. Piston refrigeration compressor corrosion mainly comes from moisture, air ingress after shaft seal leakage and acidic oil degradation products. Semi-hermetic refrigeration compressor sealed shell reduces air ingress risk, but acid formed by motor burnout will corrode internal metal parts. Cold storage refrigeration compressor core anti-corrosion measure is to maintain dry system; filter drier removes moisture and acid continuously. Once corrosion occurs, metal oxides circulate in system, abrade bearings, block oil passages and accelerate further component corrosion. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration compressor internal corrosion, refrigeration air ingress, refrigeration system moisture control, refrigeration metal particle contamination, refrigeration compressor manufacturer, cold storage refrigeration system protection, refrigeration compressor supplier
Q1: What percentage of slow hidden failures are caused by internal system corrosion? A: 27% of latent failures originate from internal corrosion and metal particle contamination. Q2: What are the main sources of corrosion inside refrigeration system? A: Moisture, air ingress and acid generated by oil degradation. Q3: Why semi-hermetic compressor has lower air ingress risk? A: Welded sealed shell, no rotating shaft seal penetrating outside. Q4: What is the primary anti-corrosion method? A: Keep system dry and use filter drier to adsorb moisture and acid. Q5: What hazard of corrosion by-products? A: Metal oxide particles abrade bearings and block oil supply channels. Q6: What field symptom indicates internal corrosion? A: Oil darkening, sludge formation and rising metal particle count in oil sample. Q7: What action must be taken if air enters system? A: Recover refrigerant, vacuum dehydration and replace filter drier.
