500M^3挖泥船主机增压器压气端污染原因分析及解决办法

某500 M3挖泥船主机在运行中先后出现过增压压力下降,功率降低,油耗及排烟温度升高,增压器轴承损坏等现象。本文通过试验事实,论证了增压器压气端污染问题是造成某500M3绞吸式挖泥船主机性能恶化,增压器轴承损坏的根本原因。同时对压气端污染产生的原因进行了分析,并提出了相应的解决办法,其中尤以采用室外吸气的方法取得的效果尤为显著。

500 M3 of a dredger in operation, the host has been pressurized pressure drops, the power to reduce fuel consumption and exhaust gas temperature rise, damage to turbocharger bearings and so on. This paper tests the facts demonstrated that the gas-side pressure turboeharger pollution problem is caused by a cutter suction dredger 500M3 performance deterioration of the host, turbocharger beafingl the root causes of damage. At the same time, gas pressure-side pollution causes were analyzed, and the corresponding solutions, pgrtieularly in the use of outdoor suction effect of the method is particularly significant
