Improper commissioning is a major cause of early failure of piston refrigeration compressor. Knowing typical commissioning errors helps engineers complete startup work safely and protect new compressor.
Over-fast refrigerant charging is one frequent mistake. Filling refrigerant quickly in large quantity causes liquid entering suction pipeline, triggering liquid slugging and breaking compressor valve plate instantly.
Skipping deep vacuuming before refrigerant filling leaves moisture and non-condensable gas inside pipeline. Non-condensable gas raises discharge pressure, moisture induces oil acidification and copper plating fault.
Ignoring crankcase heater preheating before startup is another common error. When ambient temperature is low, refrigeration oil mixes with liquid refrigerant inside crankcase. Startup without preheating leads to oil dilution and bearing abrasion.
Improper setting of pressure protection value also brings risk. If high-pressure protection threshold is set too high, the compressor cannot stop timely under overpressure and suffers permanent damage.
After commissioning, operators forget to record running parameters. Without baseline data, it becomes hard to judge abnormal operation status in future maintenance inspection.
xtldcool requires commissioning engineers to follow standard startup procedure. We supply commissioning checklist and remote technical guidance for overseas customers.
All commissioning work should be performed by certified refrigeration technicians. Untrained operators are forbidden to start and adjust piston refrigeration compressor.
FAQ
Q: What damage will rapid refrigerant charging cause during commissioning? A: Liquid enters suction line and causes liquid slugging, breaking valve plate.
Q: What problem occurs if deep vacuuming step is skipped? A: Moisture and non-condensable gas stay inside refrigeration pipeline.
Q: What function of crankcase heater before compressor startup? A: Prevent refrigerant dissolve into oil and avoid oil dilution.
Q: What risk if high pressure protection threshold set too high? A: Compressor will not shut down in time under overpressure working state.
Q: Why record running parameters after commissioning? A: Form baseline data for later fault diagnosis and maintenance.
Q: Does xtldcool provide commissioning guidance for piston compressor? A: Yes, standard checklist and remote technical support available.
Q: Who is qualified to complete compressor commissioning work? A: Certified professional refrigeration technicians.
