Semi-Hermetic Refrigeration Compressor Oil Cooler Design | Low-temperature System Overheat Control
Insufficient oil cooling causes 32% of semi-hermetic compressor high oil temperature alarm, xiteliduo Refrigeration Compressors explains oil cooler selection and commissioning. Semi-hermetic refrigeration compressor oil temperature should be controlled within 65℃~85℃. Oil temperature exceeding 90℃ accelerates oil aging and carbonization. Piston refrigeration compressor mostly relies on discharge gas heat dissipation; external oil cooler is only required for ultra-low temperature working condition. Cold storage refrigeration compressor liquid type oil cooler uses liquid refrigerant to cool lubricant; oil temperature sensor controls the cooling liquid supply valve. Oil cooler pipeline filter needs inspection every 3000 running hours. Blockage reduces heat exchange capacity and triggers oil overheating. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration compressor oil cooler, refrigeration oil temperature control, refrigeration oil carbonization, refrigeration liquid oil cooler, refrigeration compressor manufacturer, cold storage low temperature system design, refrigeration compressor supplier
FAQ
Q1: What percentage of high oil temperature alarms are caused by insufficient oil cooling? A: 32% of high oil temperature alarms result from inadequate oil cooling capacity. Q2: What is the target operating oil temperature range for semi-hermetic compressor? A: Maintain oil temperature between 65℃ and 85℃. Q3: What consequence will oil temperature over 90℃ bring? A: Lubricant aging and carbon deposit formation speed up greatly. Q4: Does piston compressor normally need external oil cooler? A: No, only ultra-low temperature systems require external oil cooler. Q5: How does liquid oil cooler work? A: Use liquid refrigerant to absorb heat from lubricating oil. Q6: What component controls liquid supply of oil cooler? A: Oil temperature sensor linked cooling liquid control valve. Q7: What inspection cycle applies to oil cooler pipeline filter? A: Inspect every 3000 running hours.
