7 solutions to reduce the noise of bucket elevator

Bucket elevators are more and more used by users, and it is inevitable that there will be some noise during use. So today, Xiaobian introduces how to reduce the noise of the bucket elevator as follows:

1. Check the condition of the head and bottom wheel bearings

The abnormal noise of the head and bottom wheels of the bucket elevator is due to poor sealing or lubrication, resulting in bearing damage and is caused by the bearing housing. Carefully check the condition of the head wheel and the bottom wheel bearing. If the bearing is damaged, it should be replaced in time.

2. Bearing failure or excessive hopper loading

Bucket elevator bearing failures are mostly caused by spillage of materials during operation. The hopper is loaded too much. During the lifting process, the material spills from the hopper and falls on the bearing, causing the bearing to lock and the operation to be inflexible.

Solution: Replace the bearing in time and clean the material spilled on the bearing.

3. The noise generated by the collision between the chain bucket and the casing

The noise generated by the collet of the bucket elevator and the casing. After the chain bucket elevator is used for a long time, the chain will be pulled to a certain extent, causing the chain to be too loose. When the hoist is swinging left and right during the running process, the hopper will easily collide with the chassis. The solution is to adjust the tensioning device so that the chain can be shaken left and right at a distance of about 3 mm.

4. The hopper is falling off, damaged or loose

The main cause of abnormal noise in the barrel of the bucket elevator is that the hopper is detached, damaged or loose. In this case, stop immediately and carefully inspect and repair the shed, damaged or loose hopper. In daily work, the hoist is used for a comprehensive inspection of the hopper for 500 hours, and whether the hopper and the hopper belt are firmly connected to ensure the stability of the hopper work. A fence is installed at the discharge port of the bucket elevator to prevent damage to other equipment after the hopper is detached.

5. Drop after the hopper falls off

The bucket of the bucket elevator falls off and falls into the body, and it will continuously collide with other components during the operation of the elevator to generate noise. The solution is to check if the hopper is loose or loose, and replace or fasten it in time. Due to the long-term operation of the hoist, the internal fuel consumption of the reducer is intensified and noise is generated without paying attention to maintenance. The solution is to check and fill the lubricant regularly.

6. The guide plate meets the hopper

 The guide plate of the bucket elevator collides with the hopper because the distance between the head wheel and the guide plate is too small, and the hopper constantly collides and rubs during the running process. In this case, if the tire is not noticed for a long time, the hopper is extremely easy to be damaged and peeled off. The solution is to adjust the position of the guide plate and increase the spacing. There is material between the guide plate and the hopper, which will lead to premature wear of the guide plate, and continuous friction during operation will generate noise. The solution is to enlarge the input angle of the material of the machine base and increase the space for the material.

7. Coupling two shafts are different

The noise of the bucket hoist coupling two shafts at different times, the coupling between the high speed end motor of the drive unit and the reducer, or the coupling with the brake wheel, this noise It is also accompanied by vibrations of the same frequency as the motor. When such noise occurs, the position of the motor reducer should be adjusted in time to avoid breakage of the input shaft of the reducer.

Here are seven solutions to solve the noise of the bucket elevator. I hope to help you reduce the noise of the bucket elevator during operation.
