Every export cold storage piston refrigeration compressor must pass a full set of factory acceptance tests before packaging. Units failing any inspection item will be disassembled, adjusted and re-tested; defective products are not allowed to enter shipment warehouse.
Helium leak detection is used to inspect sealing performance of piston compressor. The test detects tiny leakage points with sensitivity up to 1×10⁻⁹ Pa·m³/s. This strict standard avoids refrigerant leakage during long sea transportation and later field operation.
24-hour full-load continuous running test is mandatory. During the test, technicians record exhaust pressure, oil temperature, motor current and vibration data every 30 minutes. All parameters must stay within design threshold without abnormal fluctuation.
Motor winding insulation resistance and high voltage withstand test verify electrical safety. The insulation resistance should exceed 200MΩ, and winding withstands specified high voltage without breakdown. This prevents motor short-circuit fault after shipment arrival.
For customized piston refrigeration compressor with anti-corrosion coating, salt spray test sample inspection is required. Coating sample undergoes 1000-hour salt spray test without rust spot formation, confirming suitability for coastal aquatic cold storage projects.
xtldcool piston refrigeration compressor factory keeps test records of each compressor unit. The test report is attached to shipping documents, helping overseas buyers and customs verify product quality and compliance during clearance.
Visual and dimensional inspection checks casing, crankshaft assembly, valve plate and piping interface. Dimensions deviation is controlled within 0.02mm for key moving parts. Non-compliant machining tolerance will accelerate wear of piston compressor during operation.
