Semi-Hermetic Piston Compressor Power Supply & Electrical Protection Specification defines power requirement and protection logic; stable power supply and complete electrical protection prevent motor burnout caused by abnormal power quality. A professional refrigeration compressor supplier reviews site power capacity, cable cross-section and protection device selection; power quality test is recommended before commissioning for large rack projects. Refrigeration compressor factory adopts IQC, IPQC and FQC three-stage inspection system; all test data is bound to compressor serial number and stored permanently. Refrigeration compressor manufacturer holds ISO9001 and ISO14001 certificates; export compressor models need CE and RoHS certification for overseas bidding. How to configure electrical protection shall include phase loss, phase imbalance, overcurrent, overvoltage, undervoltage and motor thermal protection; protection device response time shall match compressor characteristics. Refrigeration compressor comparison shows semi-hermetic piston motor is vulnerable to phase loss damage; electrical protection is more critical than for scroll compressors in sites with unstable grid. Xiteliduo semi-hermetic refrigeration compressor assigns unique serial number to every finished unit, binding material batch, assembly operator and all test data. Piston refrigeration compressor must pass 2.5MPa pressure holding air tightness test before delivery; test result is recorded and linked to compressor serial number. Refrigeration compressor quotation shall list host, spare parts, packaging and freight separately; power quality detection service and electrical protection components can be added as optional service. Refrigeration compressor common electrical faults: phase loss, three-phase unbalance, voltage fluctuation, cable overheating, contactor burnout and motor insulation aging. Cold storage project supplier audit must verify factory laboratory configuration, including performance bench, durability bench, leakage bench and vibration noise test bench. The built-in motor of semi-hermetic refrigeration compressor uses Class F insulation grade, maximum withstand temperature reaches 155℃, equipped with overheat and phase loss protection. For quick-freezing warehouse below -30℃, piston refrigeration compressor requires enhanced cooling design to handle large pressure ratio and load fluctuation. Finished compressor’s serial number is clearly marked on metal nameplate; nameplate information includes model, refrigerant, voltage and factory production date. Export refrigeration compressor adopts anti-rust treatment and fumigated wooden box packaging, with moisture-proof film for long-distance ocean shipping. Refrigeration compressor maintenance for semi-hermetic piston machine can replace bearing, piston ring and valve plate assembly on-site without cutting refrigeration pipelines. R&D team completes thermal simulation and structural fatigue simulation; vibration attenuation less than 7% after 1000 hours continuous aging test of piston refrigeration compressor. Xiteliduo piston refrigeration compressor supports R404A, R507, R134a and CO₂ refrigerants; mixing multiple refrigerants is strictly prohibited. Full-load noise of semi-hermetic refrigeration compressor shall not exceed 78dB(A), suitable for 24-hour continuous operation in cold storage machine room.
