During the operation of the coal mining chain scraper conveyor, the pulsating impact load will be applied to the scraper chain for a long time, causing fatigue damage to the scraper chain. The most easily damaged chain scraper conveyor is the scraper chain. The following factors affect the fatigue wear life of the coal mining scraper conveyor chain.
Abnormal wear can seriously affect the service life of the scraper conveyor chain, resulting in three main aspects of abnormal wear: manufacturing, installation, and operation.
(1) The influence of manufacturing quality on the wear of the scraper conveyor chain. The quality of the scraper conveyor manufacturing enterprise is not strict, and the manufactured equipment does not meet the standard, which leads to the uninterrupted meshing between the scraper conveyor chain and the wheel. The chain vibrates seriously during the work, which makes the chain wear worse.
(2) The influence of the installation quality on the wear of the scraper conveyor chain. Some irregular installations can also cause chain wear to accelerate and even break.
(3) The influence of the operating quality on the wear of the scraper conveyor chain. When the chain is not adjusted in time, the tightness of the chain may not be adjusted in time, and the large foreign matter entering the slot may not be cleaned out in time, and the chain or the scraper may be broken.
