I recently encountered several issues while operating my bucket elevator, and I’ve documented the problems and solutions I found. First off, there was an abnormal noise during operation. Upon inspection, I discovered that the bottom plate was colliding with the chain buckets. To fix this, I adjusted the elastic device on the frame to ensure proper tension for the chain. Additionally, the drive shaft and driven shaft were loose, causing the sprockets to shift and leading to collisions between the chain buckets and the casing. Tightening the key and realigning the sprocket positions resolved this issue. The guide plate also seemed to be hitting the chain buckets, so I trimmed its position slightly. There was some material caught between the guide plate and the chain buckets, which I cleared out and then widened the input angle of the material at the base. The bearings weren’t moving smoothly, so replacing them fixed the problem. I also found foreign objects stuck inside the housing, which I promptly removed. The sprocket teeth needed correction due to wear, so I either adjusted their shape or replaced the sprockets entirely.
Next, the motor base was vibrating excessively. After checking, I realized the motor rotor wasn’t rotating well, so I disassembled it to inspect for static balance issues. The alignment between the reducer and motor wasn’t precise, so I had to re-center them. The motor base’s horizontal level was off, so I adjusted it accordingly. There was an error in the transmission sprocket alignment, which I corrected. The sprocket tooth shape was worn, so I reshaped it. Finally, the tightness of the drive sprocket needed adjustment.
Regarding drainage issues, the full-length flange on the casing was leaking. I replaced the old gasket, applied sealant, and tightened the bolts again. Material was escaping through gaps at the machine head and base, so I added additional seals. The height difference in the incoming material was too great, so I increased the feeding pressure and added a buffering device to manage the flow better.
The elevator's lifting capacity wasn't meeting the design specifications. I noticed material sticking to the buckets and chutes, so I cleaned these areas periodically. The front machinery lacked sufficient capacity, throwing only a small amount of material, so I tried improving the productivity of the upstream equipment. The lifting speed was slow, so I adjusted the gear ratio of the drive sprocket. The material metering method was incorrect, so I recalibrated the system to ensure accurate measurements.
Lastly, the discharge capacity was insufficient. The rear mechanical equipment couldn’t handle the output, so I upgraded its production capacity. The discharge chute was either too small or had an improper angle, so I modified it. Again, material was sticking to the buckets and chute, requiring regular cleaning.
If anyone else experiences similar problems, feel free to reach out—I’m happy to help troubleshoot!
