Bucket Elevator Noise Analysis

 Bucket elevator machine that starts to work must be under zero load conditions, stop feeding before stopping running until the materials are totally unloaded.Feeding should be uniform, which can not exceed the rated throughput of bucket elevator to avoid the occurrence of bottom clogging phenomenon.If occurrence, must be park and clear immediately;After the first being or operated of 100 hours, should recheck ,and tighten all bolts contact joints;It should keep all lubricating points normal lubrication in the working process ;If equipped with a slow moving device, slow moving equipment must run in idle state;Regularly check the operation of various components, each connection bolts fastening, traction component and the hopper whether wear damage.If damaged, should be promptly removed and replaced.Usually as a component is not working properly and make abnormal noise.The main parts of unusual noises are coupling, the head wheel and the bottom wheel, cylinder internal etc.

1.The abnormal noise of coupling:abnormal noise of coupling issued, sometimes accompanied by vibration noise of the same frequency of rotation of the motor.The main cause of the failure is caused by before and after two different heart of coupling,Should adjust the motor and reducer position, ensure the motor shaft and the reducer shaft concentric.

2.The abnormal noise of head wheel and the bottom wheel:the noise is very small when the head wheel and the bottom wheel work correctly.When the abnormal noise , due to seal or poor lubrication, causing bearing damage, issued by the bearing seat. Carefully check the head wheel and the bottom wheel bearing condition, if bearing is damaged, should be replaced promptly.

3.The barrel of abnormal voice:the main reasons of barrel abnormal noise are falling hopper, damage or loose.As this kind of circumstance ,should immediately stop, and carefully check and if hopper damaged or loose or fall off to repair timely.In daily work, To bucket elevator hopper of every 500 working hours, conducting a comprehensive inspection included that if is intact, hopper and hopper belt is connected firmly, to ensure the stability of the work. At the same time, in the discharging outlet of bucket elevator,where is installed a fence, to prevent hopper falling, causing damage to other equipment.
