要定期检查链式输送机挠性牵引链条和头尾链轮道轨的磨损情况，磨损严重时要及时更换；检查过程中要注意挠性牵引链条上的套筒滚子因物料填塞停转由滚动变为滑动加剧磨损问题，应及时加以清除。
Regularly check the wear condition of flexible traction chain and head and tail chain wheel track of chain conveyor, and replace them in time in case of serious wear; pay attention to the problem that the sleeve roller on flexible traction chain changes from rolling to sliding and aggravates the wear due to the stop of material filling during the inspection process, and remove them in time.
链式输送机机体内输送的料位不得过高， 一般不得超过机体总高的 2／3。
The material level conveyed in the chain conveyor body shall not be too high, generally not more than 2 / 3 of the total height of the body.
链式输送机正常生产时， 应避免大块或粘湿物料及金属杂物进入链运机，否则会损坏挠性牵引件。
During the normal production of chain conveyor, large or sticky materials and metal sundries shall not enter the chain conveyor, otherwise the flexible traction parts will be damaged.
当生产条件限制不可避免地有非正常物料进入链运机时，操作者应经常注意牵引件联接轴，刮料钩等磨损情况，以免造成牵引断裂，头轮缠链等更严重的设备事故。
When the production conditions limit the inevitable entry of abnormal materials into the chain conveyor, the operator should always pay attention to the wear of the coupling shaft of the traction parts and the scraping hook, so as to avoid more serious equipment accidents such as traction fracture and the winding of the head wheel.
链式输送机运行过程中出现闷车，传动系统振动，表盘示值超常变化等情况，操作者应及时和上下工序联系，按程序停车查找原因排除故障。
In the process of chain conveyor operation, the operator shall contact with the upper and lower processes in time to find out the causes and eliminate the faults according to the procedures in case of vehicle blocking, transmission system vibration, abnormal change of dial indication, etc.
链式输送机停机前应先停止加料，待机体内物料完全卸尽时，方可停机。
Before the chain conveyor stops, the feeding shall be stopped first, and the machine can be stopped only when the materials in the standby body are completely discharged.
