Strict factory test ensures every piston refrigeration compressor works stably after delivery. Standardized inspection procedure detects defects before shipment and reduces on-site failure risk for cold storage projects.
Visual inspection is the first step. Inspect casting surface, welding seam, nameplate marking and pipe interface to check for sand holes, crack or dimension deviation.
Performance test includes 2-hour continuous running under rated working condition. Testers record pressure, temperature, motor current, vibration and noise data during the whole test period.
Leakage test applies nitrogen pressure holding test. Maintain pressure for specified time, any pressure drop beyond threshold means leakage defect and the compressor will be rejected.
Electrical safety test covers motor winding insulation resistance and protection function simulation. Phase loss, over-current and high-pressure protection functions are verified one by one.
After passing all tests, compressors are cleaned, dried and sealed. Blind flanges are fitted on suction and discharge ports to prevent foreign matter entering the cavity.
xtldcool piston refrigeration compressor factory implements full inspection for each unit. Test reports are attached to compressor shipment documents for customer reference.
Random sampling audit will be carried out periodically. The audit checks finished product quality to guarantee consistency of batch production.
