Analysis of common causes of bucket elevator
Bucket elevator widely used soda ash,cement ,chemical fertilizer ,coal,food and so on some field. It took up an important position in the related equipment composition,we will introduce bucket elevator common question and solve measures for you have.
Failure analysis of bucket elevator:
1..bucket elevator head shaft rupture.
The head shaft strength is not enough,This is mainly not heat treatment or heat treatment temperature is not enough,and the material is not reasonable,third,the head shaft design structure is unreasonable,may exist too concentrate,Four is the long-term overload operation, resulting in fatigue fracture
2.bucket elevator vibrate and noise is too big.
First,the vertical perpendicularity of bucket elevator ,Head and tail misalignment.second, there is a phenomenon of the bucket hopper card material.Three is the hopper skewed and tail axis is not horizontal, resulting in side force,Four is the chain deformation, resulting in halfway swing
3.Reducer damage.
First, when the shaft power is large,A hydraulic coupler shall be installed between the motor and the reducer,if not,is forced start will cause shaft rupture,Or the high speed gear is broken.second ,the reducer select model is smaller.third,is the reducer lubrication is not normal Causing overheating or lack of oil between teeth ,Four is the reducer quality inferior;Five is the reducer bearing damage,
4.Motor heating or burning
First, the motor design power is too small,second ,is the equipment stuck to cause stuffy car.Third , when power exceeds 30kW,not select the hydrodynamic coupling transmit,Forth is the equipment long-term overload operation; finally is the normal damage.



Solving measures:
1.head shaft breakage.
Firstly, we should analyze bucket elevator weather long-term over lading,casing rupture,should take measures to avoid overloading .Measures should be taken to avoid overloading. If material selection is not reasonable, we can choose better materials
3.Reducer damage
Replace the bearings in time and clean the bearing parts,Adjust the device and tighten the chain,The between the chain sections refers to the chain's contact with the sprocket The noise can be reduced by adding proper lubricating oil to the sprocket or chain,The noise is also accompanied by the same vibration as the motor rotation frequency. The position of the motor reducer should be adjusted in time for this noise.Failure of the input shaft of the reducer
4.Motor heating or burning
We should check power weather is too small,if appear card ,should Cut off the power immediately,Find out the cause and adjust it in time.
