物理化学方法在线清洗船舶柴油机涡轮增压器

摘要

Considering the serious carbon deposition and difficultly in maintaining the turbocharger in the marine diesel en⁃gines, a new technique is initiated synthetically to clean the turbocharger online with a physico⁃chemical method. The bench scale test shows that it is effective to remove the carbon deposition of the turbocharger and exhaust gas turbine with this technique;the vacuum degree with the crankcase and the gear case is greatly reduced after cleaning, meanwhile the performance of the turbocharg⁃er recovers and the power of the internal⁃combustion engine is improved. The contact material is not corroded by the special clean⁃ing agent supporting. The cleaning agent has good adaptability, and safe and reliable. The diesel engine runs smoothly and normally during the laundering.%针对船舶柴油机涡轮增压器积碳严重、维修保养困难的问题，提出了新研涡轮增压器清洗装置和清洗剂，综合运用物理化学方法对涡轮增压器进行在线清洗的新技术。台架试验表明：运用该技术可有效清除涡轮增压器压气机、废气涡轮内部的积碳；清洗后曲轴箱和齿轮箱内的真空度大幅降低，涡轮增压器性能恢复，内燃机功率提高；配套专用清洗剂对接触部位材料无腐蚀，适应性好，安全可靠；清洗过程中柴油机运转平稳、正常。
