Due to the bad underground environment, geological conditions and three machine cooperation, scraper conveyor has serious wear and failure. In order to prolong its service life and improve its efficiency, let's analyze the reasons.

Wear failure mainly includes:

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

Poor lubrication causes dry friction between gear teeth and bearings, or impurities exist in lubricating oil, resulting in poor engagement of gear teeth, resulting in tooth surface separation; the installed size does not meet the standard; the scraper has suffered intermittent hard impact in the working process for a long time.

2. The sprocket teeth are seriously worn or the bearing is damaged

The chain is too tight, resulting in the increase of alternating pressure on the gear teeth; the sprocket assembly fails to rotate 180 ° in time for installation after 6 months of operation; the hardness is too high; the floating sealing property of the sprocket teeth is weak; the gap between the sprocket and the bearing is large, resulting in the damage of the sealing ring.

3. Wear of middle groove

Under the bad working conditions, the middle groove bears the overload operation of the shearer, i.e. the heavy pressure of the shearer and the impact of the drum cutting the coal seam in the vertical direction; the large coal rock is stuck in the groove, the heavy pressure on the middle plate; the lateral and longitudinal forces of the push-pull hydraulic support.

4. The chain is seriously broken or worn.

In addition to the sliding friction, the chain also bears a lot of static and dynamic loads, and is eroded by mineral water.

Familiar with the causes of wear and failure of scraper conveyor, put forward preventive measures to achieve service life and improve production efficiency.
