Reasons and Solving Measures for Chain Deviation in Scraper Conveyor I

Reasons and Solving Measures for Chain Deviation in Scraper Conveyor I

1. Influence of chain deviation

Scraper chain deviation will increase the gap between blade and base groove to reduce average speed of materials. Therefore, it is so hard to increase internal and external friction that the conveying efficiency will be reduced. If the gap is too small, it will increase the transport resistance, accelerate wear of blade and machine groove, reduce equipment lifespan.

2. Reasons for chain deviation

2.1 Poor installation quality leads to scraper chain deviation

1) The straightness of whole machine is out of tolerance.

2) Head and tail wheel are misalignment.

3) Scraper chain is out of shape which will lead to chain deviation.

4) Due to different tension adjusting, tail shaft will be deflection which can cause chain deviation.

Above mentioned points can cause chain deviation, then it will lead to unstable operation of the whole machine.

2.2 Material impact causes scraper chain deviation

Due to unstable discharging points, both sides of scraper conveyor have unbalanced stress, in this condition, it is easy to lead to chain deviation.

2.3 Uncertain reasons cause scraper chain deviation

Because of the complicated stress state, even if there is good installation quality, it will be easy to arise scraper chain deviation due to the greater frictional resistance.
