Semi-Hermetic Piston Compressor Overhaul & Recommissioning Specification defines overhaul scope and restart check items; complete inspection and testing after overhaul restores compressor performance to original design level. A reliable refrigeration compressor supplier provides overhaul checklist and post-repair commissioning scheme; overhaul includes disassembly, component inspection, worn part replacement, reassembly and full functional test. 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 maintain safety stock of crankshaft, connecting rod and valve plate, lowering supply interruption probability below 3% for bulk cold storage orders. How to carry out compressor overhaul must clean internal oil sludge and foreign debris; after reassembly, air tightness test and no-load running test are mandatory before system charging. Refrigeration compressor comparison shows semi-hermetic piston compressor can be fully overhauled; rebuild capability is the main difference from disposable fully hermetic compressors which cannot be opened for internal repair. Xiteliduo semi-hermetic refrigeration compressor adopts mechanical capacity unloader structure; it enables stepwise cooling adjustment without motor frequent on-off operation. The performance deviation of semi-hermetic 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; on-site overhaul service and post-repair recommissioning can be listed as optional service. Refrigeration compressor common overhaul related risks: residual debris inside crankcase, improper assembly torque, wrong gasket installation, loose fasteners and leakage after reassembly. 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. Warranty terms can start from production date or commissioning date; manufacturing defects qualify for free spare parts replacement within agreed warranty scope.
