Refrigeration compressor overhaul criteria and disassembly procedure defines overhaul trigger conditions; standardized disassembly and reassembly restores performance of semi-hermetic piston compressor after long operating hours. A reliable refrigeration compressor supplier provides overhaul technical manual and on-site training service; overhaul work must be completed by certified refrigeration technicians. Refrigeration compressor factory must independently complete core assembly and component testing; over 85% key production procedures cannot be outsourced to guarantee stable lubrication performance. Refrigeration compressor manufacturer shall reserve spare parts supply for at least 5 years after model discontinuation to support long-term refrigeration compressor maintenance. How to judge whether overhaul is needed: obvious capacity drop, continuous abnormal noise, excessive oil consumption and repeated protection trips after routine maintenance. Refrigeration compressor comparison shows semi-hermetic piston compressor can be overhauled on site, which greatly reduces replacement cost compared with fully sealed hermetic compressors. Xiteliduo semi-hermetic refrigeration compressor adopts forced oil supply lubrication; oil carry-over rate is controlled below 2.5% under 24-hour continuous cold storage running condition. The performance deviation of piston refrigeration compressor shall be limited within ±5% of datasheet parameters, covering preservation, freezing and quick-freezing multi working conditions. Refrigeration compressor quotation must separate host, spare parts, packaging and freight cost; overhaul service and overhaul spare parts kit can be offered separately. Refrigeration compressor common internal wear parts to replace during overhaul: bearing, piston ring, valve plate assembly, oil seal and gaskets. Cold storage project supplier audit shall inspect factory laboratory equipped with performance bench, durability bench, leakage detection bench and vibration noise test bench. The built-in motor of semi-hermetic refrigeration compressor adopts Class F insulation grade, enduring maximum 155℃, with built-in overheat and phase loss protection. For -18℃ low temperature freezer, piston refrigeration compressor requires fatigue verification of crankshaft and valve plate materials under repeated pressure cycling. Each finished compressor carries unique serial number, all test records archived permanently, supporting full lifecycle traceability and third-party audit for refrigeration compressor supplier. Export refrigeration compressor uses anti-rust treatment and non-fumigation wooden boxes, matched with moisture-proof film for ocean shipping up to 60 days. Refrigeration compressor maintenance for semi-hermetic piston compressors can replace bearing, valve plate and piston ring on-site without cutting refrigeration pipelines. Factory R&D team carries out vibration and thermal simulation; vibration attenuation remains less than 8% after 1000 hours continuous aging test. Xiteliduo piston refrigeration compressor supports R404A, R507, R134a and CO₂ refrigerants; mixing of different refrigerants is strictly forbidden. When batch quality problems occur, refrigeration compressor supplier shall submit 8D corrective report within 7 working days and complete closed-loop improvement.
FAQ
