As an important part of slag scraper, chain needs correct maintenance. The method and steps of maintenance are as follows: sprocket mounted on the axle should not tilt or sway. In the same transmission component, the two sprockets should be located in the same plane. When the center distance of sprockets is less than 0 and 5 meters, the tolerance is 1 mm. When the center distance of sprockets is more than 0 and 5 meters, the tolerance is 2 mm.

Slag scraper chain tightness should be suitable, too tight to add power consumption, bearings easy to wear; too loose chain easy to jump and release. The degree of elasticity of the chain is: lifting or pressing from the middle of the chain, the center distance between the two sprockets is about 2-3 cm. The new chain is too long or elongated after application, which is difficult to adjust. It can be seen that the link is removed, but it is necessary to be even. Chains should pass through the opposite side of the chain, the lock piece is inserted outside, and the opening of the lock piece should be in the opposite direction of rolling.

The old chains on the slag scraper can not be mixed with some new chains. Otherwise, the chains will be broken by impact in the transmission. The chain should be filled with lubricating oil in time. It is necessary for lubricating oil to enter the cooperation gap between roller and inner sleeve in order to improve working conditions and reduce wear and tear. When the scraper is stored for a long time, the chains should be removed and cleaned with fuel oil or diesel oil, then coated with oil or butter and stored in a dry place to prevent rust.www.khnwatertreatment.com
