belt conveyor roller for power station

 One.application and feature

Roller are widly used in belt conveyor laoding and aligning ,made the material on the belt to the end of belt conveyor ,and unload

Roller main feature

1.Good sealability

2.withstand the axial load

3.Smooth operation, no block phenomenon

4.High universality and interchangeability

5.Easy to replacement

6.Remove the convenient, maintenance is strong, high reliability

Two.Use environmental conditions 

This series of roller can be used in coal-dust, pouring water, wet environment, have dustproof, waterproof, corrosion resistant properties.

Environmental temperature in the-10⁰C ~--40can normal operation

 Four:parts introduce

1.pipe used 20#  ERW steel pipe,all quality Accord with MT/T1019-2006

2. Bearing housing used metal stamping

3. chinese standard bearing

4: roller shaft used 45# steel

5.seals used labyrinth seals ,good quality , prevent the coal dust and water bearing

Five:Technical performance 

1,Radial beat round

2.Axial channeling move

In the 500 N axial load, the roll shaft "to move down the value of the more than 1.2 mm.

3.axial loading

5. working life:more than 20000hours

ix. working principle

Roller through roller conveyor belt and the friction between the body, to roller bearing outer ring, seals and bearing the rotary motion, and conveyer belt do with its together and realize the transmission of logistics

Seven: structure introduction

Roller structure drawing as no1 ,main roller made of  pipe shell ,shaft,bearing bearing housing  and labyrinth seals ,use inside and outside labyrinth selas ,good feature in anti- dust,anti-water

Eight:Installation and adjustment

Different conveyor structure,different roller installation method ,could accord conveyor  instruction book for installing and adjusting

Nine:use and operation

1. Roller before use carefully check appearance for serious damage phenomenon, rotating knock against roller should be flexible rotation, no card resistance.

2.The installation of the roller and depending on the type of logistics distance and conveyor characteristics by scientific computing freight volume size and decide, avoid a dredging or dense installation.

3. Roller installation should adapt to avoid mutual grinding touch

Ten: Failure analysis and ruled out

Eleven::transportation and storage

1.when loading packed in bundle,and should be strong and reliable

2.Roller should be in the well ventilated warehouse storage, storage in the nowadays to cushion the legs, prevent water erosio
