The spiral sand washing machine can be said to be an indispensable machine for sand washing. The spiral sand washing machine can clean and separate the soil and debris in the gravel. It is an important processing equipment in the construction industry and other industries. Today, Shanghai Zhuoya Mining Machinery and Let's talk about the more important parts of the spiral sand washing machine, which is the bearing of the spiral sand washing machine. This is an important pillar for the normal operation of the spiral sand washing machine. Zhuoya will tell you about some problems that will occur and How to solve.
The rotating shaft is supported and rotated by bearings, which are relatively heavy loads and parts that are prone to wear.
(1) Checking
First check the rolling elements of the bearing, whether the inner and outer steel rings are damaged, rusted, whether there are scars, etc., then pinch the inner ring of the bearing with your hand and make the bearing level, and push the outer rigid ring with the other hand. If the bearing is good, the outer steel ring When the ring rotates, it should be stable, without vibration, and without obvious stagnation. Push hard, if you feel loose when you push it, it is badly worn.
When the rolling bearing is short of oil, you will hear a noise, if you hear the noise continuously, the bearing steel ring may be damaged, if there is sand and other debris mixed in the bearing, or the bearing parts are slightly worn, there will be a slight noise .

(2) Troubleshooting
The rust spots on the outer surface of the bearing can be cleaned with sandpaper, and then add gasoline to lubricate the bearing; or if the bearing is cracked, the inner and outer rings are cracked, or the bearing is excessively worn, a new bearing should be replaced. When replacing a new bearing, please use the same bearing as the original model .
