物理化学方法在线清洗船舶柴油机涡轮增压器

Cleaning Online the Turbocharger in the Marine Diesel Engines with Physico chemical Method

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。

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.
