In addition, it introduced the constitution and the working principle of the chain tension controller; which offered technical support for reliable operation of the scraper conveyor.Keywords : scraper conv eyor; chain tensi on; con trol tech no logy煤矿井下工作面开采实践证明，刮板输送机刮板链的张紧程度直接影响输送机 的运行可靠性。刮板链过度松弛，会引起刮板链的堆舂与刮卡，易发生断链事 故；刮板链张紧力过大,会加剧刮板与中部槽的磨损，输送机无用功率增大, 降彳氐输送机的使用寿命1。因此,刮板输送机需要对刮板链的张紧力进行控制, 使其在适度张紧状态下运行。
