Soft Start Design of Controlled Transmission for Belt Conveyor
According to the request of equipment for high-power belt conveyor, the controlled soft start equipment based on PLC was designed. The soft start process was analyzed and the idea velocity and acceleration curve of start process and the driving circuit of electro-hydraulic proportional valve were given, also the control strategy was designed. Through experiments test, the electrical control system designed in this article is able to control accurately mechanical transmission and hydraulic device and can finish the soft start function for belt conveyor.
