To select a high-quality mud scraper, we can start from two aspects, one is the selection of operation bridge, the other is the selection of driving device. There are two kinds of common driving systems of scraper, one is axle-mounted gear reducer which directly drives axle rotation and the other is cycloidal pinwheel reducer which drives axle rotation through chain drive.

The advantage of choosing cycloidal pinwheel reducer driven by coupling is compact structure and low price. In general sewage treatment projects, half-bridge mud scraper can choose cycloidal pinwheel reducer driven by chain drive; full-bridge mud scraper can choose cycloidal pinwheel reducer driven by coupling, assuming that the accuracy of chain wheel and chain can not be guaranteed.

There are two methods commonly used in the mud scraper mechanism with peripheral drive. In the past, the widely used method was to weld the angle steel into an array truss and suspend it under the working bridge. The angle steel was used to connect the truss and the truss into a whole at the site when the equipment was in use. A 45 degree inclined fixed scraper was suspended under the truss.www.khnwatertreatment.com
