Title:
METHOD FOR PREDICTIVE MAINTENANCE OF CYLINDER USING PRESSURE DIFFERENCE
Document Type and Number:
WIPO Patent Application WO/2024/071598
Kind Code:
A1
Abstract:
The present invention relates to a method for predictive maintenance of a cylinder using a pressure difference, wherein a pressure difference between the internal pressure of the cylinder and the internal pressure of a main pipe for supplying the cylinder with a hydraulic pressure or pneumatic pressure supplied from a conventional pressure device is detected in an operating range in which the cylinder's rod moves forwards and backwards, thereby collecting pressure difference waveforms regarding the operating range, a threshold is set on the basis of the collected waveform information, and if the pressure difference waveform collected from the cylinder which operates in real time deviates from the threshold, a warning is issued regarding a suspicious abnormal symptom of the cylinder, such that the cylinder can be repaired and replaced at an appropriate time, thereby preventing a substantial loss which would otherwise occur if the cylinder fails.
