Fault monitoring of electric and hydraulic control system of remote control drilling rig
Abstract
It is often difficult to quickly troubleshoot and repair the complex electro-hydraulic control system of remote control drilling rigs. Therefore, it is proposed to establish its electro-hydraulic control system monitoring system to quickly find the fault point. Based on the analysis of the fault characteristics of typical load-sensitive electro-hydraulic control systems, the method of real-time monitoring of the inlet and outlet pressure and flow of key hydraulic components is adopted, and the method of periodic monitoring of the communication, control and accuracy of the electronic control components is compared in the controller. The fault status of components is determined and monitored to improve the overall construction efficiency of remote drilling rigs.
