PROCESS FOR RECORDING PUMP SURGES IN TURBO COMPRESSORS |
摘要 |
To detect a surge in a turbocompressor, the temperature at the compressor intake, or the difference between temperatures measured at different distances from the compressor intake, is subjected to a differentiation or to an operation equivalent to differentiation, thereby determining the temperature change rate. A surge is indicated when the temperature change rate is above a specified value and possibly other plausibility criteria are met. |
