Dredge Pump made in China The transmission part mainly includes bracket and bearing assembly. The pump shaft has large diameter, good rigidity and short cantilever. The dredger wn manufacturer will not bend and vibrate under harsh working conditions. Heavy duty double row tapered roller bearing and cylindrical roller bearing are selected for bearing large axial and radial load of pump. The bearing is lubricated by grease. There are seal end cover, labyrinth sleeve and labyrinth ring at both ends of the bearing body. Binzhou wn dredger pump can effectively prevent slurry and other dirt from entering the bearing, ensure the safe operation of the bearing, and have a high service life Bearing assembly During assembly, preheat the inner ring of the bearing. The temperature is not allowed to exceed 1200. The inner ring of the bearing must be close to the shoulder. For double row tapered roller bearings, the inner ring, outer ring and positioning sleeve are complete sets of components, which are not allowed to be exchanged with the corresponding parts of similar bearings. The axial clearance is guaranteed by the bearing itself. During bearing assembly, proper amount of grease should be added. Labyrinth ring and labyrinth sleeve are used for sealing of bearing end cover. When installing labyrinth ring, pay attention to relative arrangement of notch in diameter direction. Lithium grease 2 or 3 is recommended for bearing grease.Dredge Pump made in China website:http://www.delin-pump.com/dredge-pump/
