Problems solved by technology
[0002] The underwater guide wheel combination device is one of the equipment in the chain traction grid rotary grille. This device works underwater. Because it is placed in water for a long time, water enters the bearing, and the bearing is easy to rust after entering the water. As a result, the guide wheel is inflexible in operation, with high frictional resistance, high failure rate, low service life, and inconvenient repair and maintenance, which affects the normal operation of the entire grille equipment; the device generally uses rolling bearings, which are troublesome to install and require regular maintenance.
