Second, the spiral sand washing machine works: spiral sand washing machine machine rotor with central structure, spiral blades mounted on a central shaft, the reducer is connected to the central axis of the work. With the proportion of solid particles of different sand washing machine manufacturers, thus settling velocity in liquids of different principles sand washing machine network, perform a mechanical grading equipment. 2. The bearing troubleshooting rotating shaft supported by bearings, is the heaviest part, is likely to wear member. ① troubleshooting operation inspection; sand washing machine, you will hear when Rolling starvation "Gulugulu" sound; if not hear continuous "stalk stalk" sound, may be bearing steel ring rupture. Bearing sand and other debris mixed with mild wear or bearing parts, it will produce a slight noise. After disassembly inspection; first look at the rolling element bearings, inner and outer rims for damage, corrosion, scars, etc., and then hand pinch the bearing inner ring, and bearing settle, pushing the other hand just outside the circle, if the bearing good sand washing machine, outside rims should be smooth rotation, rotation and vibration obviously catching phenomenon, stopped after the outer rims no setbacks. Otherwise, it means bearing can not be used again. Left stuck outer ring, right hand and hold in the rims, push hard in all directions, was very loose if the push is badly worn. ② rust troubleshooting bearing on the outer surface of the available 00 sandpaper to erase, and then placed in clean gasoline; or bearing cracks, chipping or bearing inner and outer rings when excessive wear, should be replaced with new bearings. When replacing the new bearings, to use the same model with the original bearings. Zhaodong sand washing machine, Yuxin Senda, sand washing machine factory, Ltd. Henan new Senda by heavy machinery.
