During the use of the scraper conveyor, due to the adverse environment of the underground, geological conditions and the cooperation of the three machines, or improper use, it will cause severe wear and failure. In order to ensure the service life of the scraper conveyor, we must use it reasonably and correctly to increase the service life and improve the work efficiency.

　　In the process of use,the wear failures are mainly caused by the following reasons:

　　1.The reducer has vibration noise or cannot bear heavy load

　　(Poor lubrication,resulting in dry friction movement between gear teeth and bearings,or the presence of impurities in the lubricating oil,resulting in poor meshing of gear teeth,resulting in tooth surface detachment;installation dimensions are not up to standard;during scraper operation Sustained intermittent hard shocks for a long time.)

　　2.Sprocket tooth wear or bearing damage

　　(The chain is too tight,causing the alternating pressure on the gear teeth to increase;the sprocket assembly has not been turned 180°in time for 6 months of installation;the hardness is too large;the floating seal of the sprocket teeth is weak;Large,causing damage to the seal ring.)

　　3.Middle groove wear

　　(The middle trough is subjected to overloading operation of the shearer under harsh working conditions,that is,the vertical pressure is applied by the shearer and the impact of the drum cutting the coal seam;large coal rocks are stuck in the trough,and the Heavy pressure;lateral and longitudinal forces of the push-pull hydraulic bracket.)

　　4.The chain is severely broken or worn.

　　(In addition to the effect of sliding friction during the operation of the chain,it must also bear large static and dynamic loads,and be subject to erosion by mineral water.)

　　After we are familiar with the cause of the wear failure of the scraper conveyor,we take preventive measures to use it properly to achieve service life and improve production efficiency.Quality is the guarantee of safety and the standard of survival for manufacturers.Luoyang Yuanjian Mining Equipment Co.,Ltd.goes through layers of control from material selection to finished product,and the quality is trustworthy.
