Abstract
A compression machine (compressor 4 and/or pump 5) of the plant (1) for the treatment of a fluid, typically by pressure swing adsorption, comprises at least one detector (7) for detecting clearance between a moving part (6) and a stator and delivering a measurement signal used so as to vary, depending on this measurement, the operation of the plant and especially to automatically shorten the phases during which the machine is running at an excessively high speed.
Claims17
Method of regulating a fluid treatment plant including at least one fluid compression machine, which comprises:
- measuring, while said compression machine is in operation, at least one clearance between two components in relative motion of the machine;
- and
- varying the operation of the fluid treatment plant according to this measurement.
A fluid treatment plant comprising at least one fluid compression machine having at least one moving part in a stator in order to inject a stream of fluid into at least one region of the plant and/or to extract a stream of fluid therefrom, the compression machine comprising at least one detector which detects clearance between one region of the moving part and the stator and delivers a signal, and a control device which varies the operation of the plant in response to said signal.
