摘要: The invention provides a transmission pipeline having self-detection function and based on the flexoelectric theory. comprises circular ring-shaped pipeline, electrodes,a charge amplifier an information acquisition after-treatment part, wherein electrodes are positioned at inner side outer of pipeline; is made dielectric substance can be used for transmitting liquid air; negative end connected with electrode positive which both grounded; output part. When free damages has no load outside, when fluid normally transmitted inside electric generated signal to via electrodes, output; suddenly broken or subjected impact periodic due defects in normal use, polarized generates polarization charges because existence effect, voltage signals part compared obtain damaged loaded position pipeline.
