燃气轮机在配置盐雾系统的试验台上，进行模拟海洋盐雾环境下长时间运行，分别测试低压压气机进口管道、第3级、第6级、第9级壳体的空气含盐量，结果表明空气中的盐雾在低压压气机已全程沉积。在海洋盐雾环境下长时间运行，通过计算得出折合低压压气机转子转速、折合高压压气机后空气压力，根据分析转速差值可表明压气机的污染情况，进而确定通流清洗时机，该方法已广泛应用于海洋用燃气轮机，燃气轮机运行维护具有重要意义。
The gas turbine was operated for a long time in a simulated marine salt spray environment on a test bench equipped with a salt spray system. The air salt content of the low-pressure compressor inlet pipeline, the 3rd, 6th, and 9th stage shells were tested, and the results showed that the salt spray in the air had been deposited throughout the low-pressure compressor. Running for a long time in an ocean salt spray environment, the rotor speed of the low-pressure compressor and the air pressure after the high-pressure compressor are calculated. Based on the analysis of the speed difference, the pollution situation of the compressor can be indicated, and the timing of flow cleaning can be determined. This method has been widely used in marine gas turbines, and the operation and maintenance of gas turbines are of great significance.
