Cold Storage Refrigeration Compressor Project Acceptance Checklist | Commissioning Test Items
Incomplete commissioning inspection causes 24% of early-stage cold storage compressor operational faults, xiteliduo Refrigeration Compressors provides acceptance test checklist for project handover. Piston refrigeration compressor commissioning includes 2-hour continuous running test. Record suction pressure, discharge pressure, oil pressure and temperature every 15 minutes. Semi-hermetic refrigeration compressor commissioning needs protection function simulation test. High pressure, low oil pressure and over-temperature protection must trigger correctly. Cold storage refrigeration compressor oil pressure should maintain 0.2 MPa to 0.4 MPa higher than suction pressure under stable operation. After commissioning, system tightness test shall be repeated. Pressure drop within 24 hours cannot exceed 0.02 MPa before formal handover. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration compressor commissioning, refrigeration compressor project acceptance, refrigeration compressor tightness test, refrigeration compressor protection simulation, refrigeration compressor manufacturer, cold storage project handover, refrigeration compressor supplier
FAQ
Q1: What percentage of early compressor faults are caused by incomplete commissioning? A: 24% of early operational failures come from insufficient commissioning inspection. Q2: How long continuous running test for piston compressor commissioning? A: 2 hours continuous rated running test with periodic data logging. Q3: What oil pressure differential above suction pressure should be maintained? A: Oil pressure stays 0.2 MPa to 0.4 MPa higher than suction pressure. Q4: What protection functions require simulation test in semi-hermetic commissioning? A: High pressure, low oil pressure and over-temperature protection functions. Q5: What is acceptance standard for 24h static tightness test? A: Pressure drop less than 0.02 MPa within 24 hours static pressure holding. Q6: What data should be logged during commissioning running test? A: Suction pressure, discharge pressure, oil pressure and temperature. Q7: What happens if protection functions fail simulation test before acceptance? A: The compressor cannot be handed over for formal operation before correction.
