 Hydraulic and electrical control devices with the regulator, a good solution to the conveyor and the slow-start power balance this problem. Hydraulic speeder carrying capacity 40% larger than the YL-type coupling, starting acceleration in 0.1m / s2 ~ 0.3m / s2 within the range stepless, multiple hydraulic control devices can be used simultaneously to meet the needs of coal mine production .
2.3 PLC control system
Large angle belt conveyor formulated with advanced computerized programmable controller PC. Control and protection functions, has a slow start and multi-motor drive power balance automatic adjustment function, easy to expand, a simple circuit structure, easy maintenance, high reliability, and has the following features:
2.3.1 continuous detection of motor speed or line speed tape, each motor load starting sequence, respectively. Small impact on the grid;
2.3.2, with overspeed and slipping protection; use PC-speed counter module, the preset limits on speeding and skidding lower limit, when the count value of the high-speed counter exceeds or falls below the preset, PC internal relay, implement overspeed or skid protection. PC─.4, more optimized component parts
2.4.1, hydraulic speeder single power up to 650kw.
2.4.2, using planetary gear reducer, small size, large carrying capacity, high transmission efficiency, low noise.
2.4.3, modified to drive roller frame tripod shape, reducing the volume of the head frame;
