1. The Influence of Chain Deviation of Buried Scraper Conveyor
1) The chain deviation causes excessive clearance between the scraper and one side of conveyor trough, which will reduce material average speed, be not good for material internal friction increase and the overcome of external friction resistance between material and trough wall, eventually reduce the conveying efficiency. On the contrary, undersized clearance will increase the conveying resistance, accelerate the wear of scraper and conveyor trough, and finally reduce the conveyor service life.
2) The chain deviation increases the noise, which is caused by the crash between scraper and conveyor trough wall, and causes the scraper damage further.
2. The Reason Analysis of Chain Deviation
1) Poor installation quality leads to chain deviation.
-The straightness accuracy of whole conveyor is out of tolerance.
-The head and tail pulleys are not on one center line.
-The pulley and shaft are deflective installation.
-Conveyor casings are deforming.
-Conveyor chains are deforming.
-The wear of rail is uneven.
-The inconsistent tension adjustment leads to tail shaft deflection.
Above conditions can lead to chain deviation.
2) Material impact leads to chain deviation.
The unstable material drop point causes the uneven pressure on both sides of scraper, which is easy to cause the chain deviation phenomenon.
3) Uncertain factor leads to chain deviation
Due to the complicated force conditions, long distance buried scraper conveyors or the ones with large-sized trough, often have chain deviation phenomenon because of existing larger frictional resistance, even if they are well installed.
