Following standardized startup sequence protects piston refrigeration compressor from avoidable damage. Wrong operating steps are a major trigger of early failure for newly installed cold storage equipment.
The first step before startup is checking all isolation valve status. Confirm suction and discharge service valves are fully open, and all maintenance blind plates are removed from pipelines.
Check crankcase oil level through sight glass. Oil should stay within the marked range. Too high or too low oil level will bring risk during compressor running.
Power on crankcase heater and keep heating for sufficient time. For low-temperature piston compressor, preheating time usually lasts several hours to release refrigerant dissolved in lubricant.
Inspect control system and protection interlock. Test high pressure, low pressure and oil differential pressure protection function manually to confirm alarm and shutdown action works.
Start auxiliary equipment first: condenser fan or cooling water pump must run before compressor startup. Without heat dissipation equipment working, compressor will hit high-pressure alarm within short time.
After auxiliary equipment is stable, trigger compressor startup. Monitor pressure, current and oil level for the first 30 minutes continuously, record all parameters into operation log.
xtldcool provides on-site startup guidance checklist for overseas clients. Operators must finish all pre-start inspection items before powering on piston refrigeration compressor.
