MEASUREMENT OF PRESSURE DIFFERENCES IN HYDRAULIC DRIVE WITH FLEXIBLE PIPE AT ESTIMATION OF HYDRAULIC SYSTEM STATE |
摘要 |
FIELD: instrumentation.SUBSTANCE: this method consists in fitting the measuring element composed by force transducer or displacement transducer on flexible pipe outer surface with preload of 300-400 N and feeding of measured pressure medium. Measured pressure medium flowing in pipe for 5-10 seconds, measured magnitude is fixed and obtained readings are calibrated. Variation of forces or displacements caused by pre-compressed flexible pipe to act on measuring element is fixed to define the pressure in hydraulic drive.EFFECT: measurement of pressure in hydraulic drive without breaking the pipe integrity tightness.2 tbl, 5 dwg |
