china coal 0001 Introduction Of XTZZL Intelligent Tensioning System 1. China Coal Group's intelligent tensioning system has double top or multiple top synchronous tensioning, automatic measurement of oil pressure and top extension, which can simultaneously control the strength and elongation, reduce the error accuracy can reach 1% FS. 2. Using the hydraulic circuit self-locking function, it can maintain the state of the oil cylinder for a long time after stopping the oil supply. 3. According to the parameters, it is automatically verified whether the tension is qualified during the tensioning process, and the elongation is excessively long or insufficient for automatic shutdown. Automatic or manual compensation is performed according to actual conditions. 4. It adopts servo control system, touch screen operation, imported PLC control, digital control hydraulic pump station main and auxiliary stations and computer wireless connection, remote operation. Easy to move, operating system is easy to learn. 5. Record tension data in real time, automatically organize data, generate reports, and intelligently manipulate tensioning processes to truly realize intelligent operations.
