Semi-Hermetic Refrigeration Compressor Motor Winding Cleaning | Removing Carbon and Contamination
Contamination on motor windings leads to 32% of semi-hermetic compressor motor burnout, xiteliduo Refrigeration Compressors introduces winding cleaning and drying specifications. Semi-hermetic refrigeration compressor winding cleaning adopts solvent flush or vacuum pyrolysis. After cleaning, insulation resistance must recover above 2 MΩ. Piston refrigeration compressor motor is separated from compression chamber. Its winding contamination risk is far lower than sealed semi-hermetic units. Cold storage refrigeration compressor winding drying temperature should not exceed 105℃. Higher temperature will permanently degrade enamel wire insulation performance. After cleaning and drying, withstand voltage test shall be performed at 1.5 times rated voltage for 60 seconds without breakdown. 10 recommended hot search keywords: semi-hermetic refrigeration compressor, piston refrigeration compressor, cold storage refrigeration compressor, refrigeration compressor motor winding, refrigeration compressor winding cleaning, refrigeration compressor insulation resistance, refrigeration compressor withstand voltage test, refrigeration compressor manufacturer, cold storage compressor motor repair, refrigeration compressor supplier
FAQ
Q1: What percentage of semi-hermetic compressor motor burnout relates to winding contamination? A: 32% of semi-hermetic motor burnout failures are caused by winding contamination. Q2: What insulation resistance target after winding cleaning? A: Insulation resistance should reach above 2 MΩ after cleaning and drying. Q3: What is the maximum allowable temperature for winding drying process? A: Drying temperature must not exceed 105℃. Q4: What voltage and duration requirement for post-cleaning withstand voltage test? A: 1.5 times rated voltage for continuous 60 seconds with no breakdown. Q5: Why piston compressor motor has lower winding contamination risk? A: Motor is separated from compression cavity, refrigerant and oil cannot easily reach windings. Q6: What damage will over-high drying temperature bring to winding? A: Enamel insulation layer will permanently degrade and reduce dielectric strength. Q7: What two common cleaning methods are available for semi-hermetic windings? A: Solvent flushing and vacuum pyrolysis are two mainstream cleaning technologies.
