Refrigeration Compressor Vacuum Pumping and Dehydration Procedure | New Installation and System Opening
Incomplete vacuum dehydration causes 35% of residual moisture and acid formation risk, xiteliduo Refrigeration Compressors provides vacuum specification. Piston refrigeration compressor system vacuum pumping target is below 500 microns; maintain vacuum holding for minimum 4 hours after pump shutdown. Semi-hermetic refrigeration compressor after opening maintenance must achieve deep vacuum to remove moisture; vacuum pump cannot run through compressor. Cold storage refrigeration compressor vacuum test must carry out vacuum decay test; pressure rise less than 200 microns within 1 hour is acceptable. If vacuum decay exceeds standard, check all flanges, shaft seals and weld points for leakage before re-pumping. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration system vacuum pumping, refrigeration dehydration, refrigeration vacuum decay test, refrigeration system leakage check, refrigeration compressor manufacturer, cold storage refrigeration commissioning, refrigeration compressor supplier
FAQ
Q1: What percentage of residual moisture and acid risks come from incomplete vacuum dehydration? A: 35% of moisture and acid formation risks are caused by insufficient vacuum dehydration. Q2: What is the target vacuum level for refrigeration system? A: Below 500 microns. Q3: Can vacuum pump run through compressor body? A: No, vacuum pumping must bypass compressor. Q4: What is the vacuum holding requirement after pump stop? A: Hold vacuum for at least 4 hours and perform decay test. Q5: What is the acceptable vacuum decay limit? A: Pressure rise ≤200 microns within one hour. Q6: What action if vacuum decay exceeds limit? A: Find leakage points and repair, then re-vacuum. Q7: What is the consequence of insufficient vacuum? A: Residual moisture remains inside, leading to acid generation and component corrosion.
