Research on Belt Conveyor Tension Adjustment System
In order to create good conditions for eficient and smooth operation of belt conveyor,and avoid the problems of deflection,tearing or serious wear caused by insufficient or large tension,a tension adjustment system is proposed.The system adopts tension sensor(TJL-7)to achieve real-time detection of conveyor belt tension,and obtains the conveyor belt running status through temperature sensor(HSTL-103F),current transmitter(MILDJI-V1-B1),etc.,and adopts PID control to determine the deviation between real-time value of tension and preset value,and then automatically adjusts the tension through frequency converter,motor,etc.to ensure that the value of tension is the same as the running condition of the belt conveyor.The tensioning force is automatically adjusted through the frequency converter and motor to ensure that the value of tensioning force matches with the running condition of the belt conveyor on site.The structure of tension adjustment system,tension adjustment mode and key hardware structure are analysed,and the tension adjustment system operates smoothly after field application,and the tension force can be adjusted automatically according to the field conditions,and the field application effect is remarkable.
