英国杰弗里·戴蒙德(BJD)公司生产的300kW萨普马迪克(Supermatic)双滚筒采煤机(以下简称BJD采煤机)的总能源采用F35型水冷感应电动机,牵引系统采用R11型液压牵引装置。F35电动机的功率为300kW,额定电压1100V,额定电流205A,起动电流为额定电流的6.5倍,空载电流约70A。R11牵引装置的最大牵引力为34t,工作油最大压力125bar,牵引速度0～7.5m/min。H_(33A)型负荷控制装置(以下简称H_(33A)),是BJD采煤机自动牵引时的负荷自动控制组件,在给定牵引速度后,通过它和它控制的电磁阀实现均衡功率牵引。当电动机过载时,它能自动切断有关电磁阀的电源,使R11牵引装置的牵引速度自动下降直至为零,过载原因消除后又自动激励相应电磁阀,并恢复到原定牵引速度;在R11牵引装置
The total energy of 300kW Supermatic double drum shearer (BJD coal shearer) produced by British Jeffrey Diamond (BJD) Company adopts F35 water cooled induction motor, and the traction system adopts R11 type hydraulic traction Device. F35 motor power 300kW, rated voltage 1100V, rated current 205A, starting current of 6.5 times the rated current, no-load current of about 70A. R11 traction device maximum traction of 34t, the maximum working pressure of 125bar, traction speed 0 ~ 7.5m / min. The H_ (33A) type load control device (H_ (33A)) is an automatic load control component of BJD shearer when it is automatically towed. After a given traction speed, it achieves balanced power traction through the solenoid valves it controls . When the motor is overloaded, it can automatically cut off the power supply of the solenoid valve so that the traction speed of the R11 traction device automatically decreases until it reaches zero. After the elimination of the overload causes the corresponding solenoid valve to be automatically energized and returns to the original traction speed, traction at R11 Device
