Abstract: In order to solve the problems of instability in hydraulic automatic tensioning system for belt conveyor, after the analysis of the working process about being used hydraulic tensioning system for belt conveyor in power plant, the workings and the advantage were firstly established. The essential relation of electrohydraulic control in the application of belt tension was discussed. Then, the disadvantages of hydraulic system were parsed, according to the different current malfunctions, methods of diagnosis analysis and disposal were provided. The integrative improvement countermeasure on the hydraulic automatic tensioning system was provided lastly. The experimental results show that methods of malfunction disposal and improvement countermeasure can effectively enhance the security and reliability of working belt conveyor.
Key words: coalfired power plant; belt conveyor; hydraulic automatic tensioning system; disadvantage analysis; malfunction analysis; improvement countermeasure
