根据船舶机舱油气释放特性和环境特点，利用舱室环境集总参数模型，提出主齿轮机组油气释放速率的计算方法，并结合某型船舶的实测数据，计算了不同主齿轮机组输出转速下的油气释放速率，对比了集总参数模型对连续变工况下的机舱油气浓度预测效能。同时，初步研究了油气释放速率与主齿轮机组输出转速之间的相关性，对船舶油气净化系统设计和污染控制具有一定的参考意义。
According to the oil and gas release characteristics and environmental characteristics of the ship's engine room, this paper proposes the calculation method of the oil release rate of the main gear unit by using the climatic parameter model of the cabin environment. Combined with the measured data of a certain type of ship, the output speed of different main gear units is calculated. The oil and gas release rate is compared with the lumped parameter model to predict the engine oil and gas concentration under continuous variable conditions. At the same time, the correlation between the oil release rate and the output speed of the main gear unit is preliminarily studied. Pollution control has certain reference significance.
