Hydraulic Pipeline Fault Mornitoring of Mine Machinery by Electrostatic Method

We adopt electrostatic sensor and parameter measurement method to monitor mine machinery hydraulic pipeline safety. We detect oil velocity of pipeline by cross-correlation principle, and complete rapid oil velocity monitoring of mine machinery hydraulic pipeline, and detect and report hydraulic equipment fault. We measure and prove mine machinery pipeline oil velocity combined with self experimental device. By analyzing a measured random signal, the diagnostic of hydraulic system pipeline fault protects the safe operation of mine machinery.
