Wharf Belt Conveyor

Wharf Belt Conveyor

Wharf Belt Conveyor is widely used in mining, metallurgy, coal and other departments, for conveying bulk materials or items, according to the transportation process requirements, they can be singly used, can also be multiple consisting of or with other equipments to form a horizontal or inclined conveying system, to meet the different arrangement of the operation line need. Wharf Belt Conveyor can be used in ambient temperature from -20 DEG to 40 temperature range, the conveying of the material at 50 DEG C below.

The advantages of Wharf Belt Conveyor

large conveying capacity, simple structure, convenient repair, standardized components.

Wharf Belt Conveyor belt heavy load starting requirements

When the Wharf Belt Conveyor belt material for some reason after the stop, restart belongs to heavy load starting. Requirements of belt conveyer for the inverter can strip heavy load starting. Wharf Belt Conveyor belt material in heavy load starting of motor, the torque output,, to overcome the static friction resistance moment caused between the belt below each of the supporting roller and the roller shaft, but also to overcome the resistance moment of the materials caused by downward pulling force on the belt.

The moment of resistance material caused a downward pulling force on the belt is constant. But the static friction force than the dynamic frictional force is larger, which makes the initial starting torque to overcome the static friction resistance moment, than dynamic friction caused by normal operation much more. Therefore, the inverter must have low speed high starting torque function.

Practice at the start of the process, due to the scalability of belt, each wheel is successively sequentially rotated, will not rotate at the same time. Even if the roller to rotate, due to low speed, lubrication between the roller and the roller shaft is not good, will be very astringent, the dynamic friction is not stable, so the torque at the start of a certain fluctuation.

But in the boot process, requires a certain amount of time, in order to make all the rollers are rotated, torque began to fall. Only reaches a certain speed, improve the lubrication, can reduce torque fluctuation. Therefore this large low-speed torque, is the need to maintain a certain amount of time, generally at least a few seconds. The minimum speed length and starting and the belt, and the scalability and other relevant. But when starting as low speed, torque and speed will be relatively large fluctuations.
