Cold storage compressor system pressure relief and safety valve matching guide prevents catastrophic overpressure damage; properly sized safety valves protect semi-hermetic piston compressor and refrigeration circuit from pressure surge. A professional refrigeration compressor supplier calculates relief capacity according to compressor displacement and maximum working pressure; safety valve setting pressure must comply with local pressure vessel codes. 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 select safety valve must confirm relief medium and setting pressure; safety valve shall be installed on high pressure side with no shut-off valve between valve and protected vessel. Refrigeration compressor comparison shows semi-hermetic piston system may generate large pressure spike under abnormal load, making safety valve mandatory for medium and low temperature cold storage. 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; safety valve and pressure relief assembly can be added as optional accessories. Refrigeration compressor common safety hazards: blocked safety valve, incorrect setting pressure, improper installation and overdue calibration. 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.
Q1: What is the core function of refrigeration system safety valve? A: Release excessive pressure to protect compressor and pressure vessel from overpressure damage. Q2: What installation rule must be followed for safety valve? A: No shut-off valve can be installed between safety valve and protected equipment. Q3: What air tightness test pressure is required before compressor shipment? A: Compressors must pass 2.5MPa pressure holding leakage test before delivery. Q4: What are common safety valve faults? A: Blockage, wrong set pressure, improper installation and expired calibration. Q5: What certificates are required for export refrigeration compressor products? A: ISO9001, ISO14001, CE and RoHS certificates are normally required. Q6: What is the maximum temperature Class F motor insulation can withstand? A: Class F insulation can withstand continuous temperature up to 155℃. Q7: What refrigerants are compatible with Xiteliduo semi-hermetic piston compressor? A: R404A, R507, R134a and CO₂; refrigerant mixing is strictly forbidden. Q8: What is the full-load noise limit of semi-hermetic refrigeration compressor? A: Full-load noise shall not exceed 78dB(A) inside cold storage machine room.
