The selection and use of conveyor


A conveyor belt in use for some time becomes longer is how

Belt will stretch during use, some of which are elastic elongation, after the abolition of the external energy restitution, the other part is the preparation of skeleton

material shrinkage elongation, this part can not be restored. Top fabric core conveyor belt, EP belt elongation is relatively small, the NN conveyor belt elongation is

relatively large, and in the course, NN conveyor after the nylon fiber creep force is relatively large, so in the course of , the elongation ratio increased, but also because

the fiber creep, so after the abolition of external forces, can shrink the amount of back much smaller than the elongation.industrial belt conveyor

Second, how to buy conveyor belt:

An accurate description of the specific name of the material, nature. Especially the size, temperature, whether with acid, alkali and other corrosive and special requirements.

Such as temperature resistant conveyor belt to be described.

2, specify the application, requirement specifications (width, length, number of layers, thickness, etc.), especially the use of heat-resistant conveyor belt temperature and

volume size.

1, the conveyor belt in the transport and storage, should be kept clean to avoid direct sunlight or rain and snow Baptist leaching, prevent acids, alkalis, oils, organic

solvents and other substances in contact and one meter away from the heating device.

2, the conveyor belt when the warehouse storage temperature should be maintained between a 18-40 ℃, relative humidity should be maintained at 50 - 80%.

3, the conveyor belt during storage, the product must be placed into a roll, not folded belt should be turned over once every quarter.

Third, the conveyor belt is what causes deviation

Deviation conveyor belt body has the following main reasons:Airport conveyor

1, in the weaving process caused by uneven tension while tightening loose side.

2, while both sides of varying thickness to thin thick side.

3, flame retardant mixed with tension to the production process.

Fourth, ensure proper use of conveyor belts:

1, to prevent the belt load start.

2, the conveyor belt deviation occurs, you should take timely measures to correct it.

Three different types, specifications layers should not be connected together using a conveyor belt, the best use of their joint bonding method.

4, the conveyor belt of the type, structure, size, number of layers should be based on the conditions of use reasonable choice.

5, the conveyor belt running speed is generally not more than 2.5m / s, large blocks, abrasive materials and the use of a large fixed pears slow unloading device should be

adopted.

6, roller conveyors and belt drive pulley diameter relationship between fabric layers, drive pulley, bend pulley supporting roller groove angle as well as the requirements of

transport should be based on design requirements, a reasonable selection.

7, the feed should be directed to the running direction along the conveyor belt, the whereabouts of the material in order to reduce the impact on the conveyor chute should be

adopted to reduce the material gap distance; belt by feeding section, should be shortened idler spacing and using buffer roller to drain material, conveyor conform with soft

moderate blocking plate to avoid stalls plate mark, scratch conveyor belt surface.

8, the conveyor is in use, the lack of any roller should be promptly added and repaired; roller covered by material, causing rotation ineffective to prevent leakage of material

between the card in the drum and tape, note conveyor lubricating moving parts, but not oil belt.

9, to avoid being conveyor rack, pillars or massive block of material, to prevent the misfortune to scratch rip and found conveyor local damage, the application of rayon timely

repair to avoid expanding.
