Semi-hermetic piston compressor vibration and noise control specification reduces vibration transmission; proper vibration isolation protects piping, valves and building structure in cold storage machine room while lowering noise pollution. A professional refrigeration compressor supplier provides vibration calculation and base selection recommendation, helping engineering contractors match vibration isolator according to compressor mass and operating frequency. Refrigeration compressor factory implements 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 variants pass CE and RoHS certification for global project bidding. How to choose refrigeration compressor vibration isolation components must consider static load and natural frequency mismatch; improper isolator selection causes resonance and amplified vibration. Refrigeration compressor comparison shows semi-hermetic piston units generate higher low-frequency vibration than scroll compressors, so rigid base plus spring isolator is commonly required. Xiteliduo semi-hermetic refrigeration compressor optimizes crankshaft balance structure to reduce inherent excitation force; vibration attenuation remains less than 7% after 1000 hours continuous aging test. 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 lists host, spare parts, packaging and freight separately; vibration isolators and noise reduction hoods can be added as optional accessories. Refrigeration compressor common faults induced by excessive vibration: pipe fatigue cracking, loose bolt connections, oil seal leakage and abnormal valve plate wear. 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 frequent 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. 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.
