Belt Conveyor Operating Deviation 3 Laws, 6 Causes and 5 Ways to Prevent Operating Deviation No more worries about belt conveyor operating deviation!

Shandong Fengke belt conveyor, also known as belt conveyor, is mainly used for loading and unloading, transferring and transporting goods and materials, which is mainly used in mineral mining and port terminals. With the development of technology, belt conveyor also plays an important role in other fields.

Belt conveyor is through the roller, roller and belt friction, friction interaction to drive the belt movement, so as to play the function of conveying goods or materials. Belt is the bearing structure of belt conveyor and also its basic traction structure. The operation of the belt conveyor is mainly affected by the friction, if the friction is not balanced or inconsistent direction will lead to the belt conveyor belt deflection phenomenon, so that the operation of the belt conveyor abnormal.

The law of belt conveyor deflection

The law of belt conveyor deflection is mainly reflected in three aspects:

First, the deviation is not in front of the back. Belt conveyor in the actual operation process, due to the running direction of the belt and its opposite, while the roller and the roller is not in the running direction of the vertical section, belonging to a side of the front side of the back, easy to cause the belt conveyor to run off the situation.

Secondly, the bias is not loose. Belt conveyor in the operation process need to carry a large load, so often in the fatigue running state. If the belt on both sides of the tension is not the same, the phenomenon will occur.

Thirdly, it is high but not low. Belt conveyor in the operation process by friction and pressure, the belt on both sides is difficult to the same level, it will run on the higher end, affecting the normal operation of the belt conveyor.

The harm of belt conveyor deflection

Belt conveyor deflection leads to production stoppage, will to a certain extent on the production safety impact, easy to induce the occurrence of safety hazards. If the deviation is serious, it is easy to cause the phenomenon of the belt rolled over the material, and the excessive force on one side will cause the belt to break laterally, which will threaten the personal safety of the surrounding staff. At the same time, the belt deflection is easy to cause material spillage, not only waste and clean up is also difficult, resulting in pollution of the production environment.

Belt conveyor deflection reasons

Belt device aging

Belt conveyor running for a long time, device wear, aging, staff failed to device timely update and adjustment, improper installation will directly cause the belt running on both sides of the tension is different, the corresponding friction is different, which will cause the run off. From the actual application situation, the main reason for the uneven force on both sides of the belt conveyor is the aging of the belt device.

Improper placement of materials

Belt conveyor in the process of transmission operation, the position of the material on the belt should be uniform and appropriate, uneven placement will cause the belt in the process of running bias. The main reason for uneven feeding is that the position and direction of the material falling is not correct, if the material is biased to the left, then the belt will run to the left, and vice versa.

Belt joint problem

Belt joints become uneven due to wear and tear caused by long-term use, or joint damage caused by human reasons. The belt is not straight or the vulcanized joint is not correct, which will cause the tension on both sides of the belt is not consistent, the belt in the process of running to the side of the tension will run to the side of the deviation, which to the belt joints run to the angle of the deviation is large.

Belt deformation and aging, tension reduction

Belt conveyor long-term operation, maintenance and renewal work if not in place, excessive wear parts, belt aging and relaxation, will gradually produce unrecoverable deformation aging, directly resulting in the reduction of tension. This will directly cause the internal stress of the uneven, so that the belt deflection.

Uneven tension at both ends of the belt

Belt conveyor is an important carrying mechanism for the belt, which is responsible for the heavy responsibility of material transportation, therefore, if the quality of the belt is not satisfactory or the belt is used for a long time, wear and aging, the tension at both ends of the belt is not balanced, resulting in the deviation. Especially the belt joints or not straight to run off the situation is obvious.

Roller, roller sticking material

Belt conveyor in the delivery of materials for a period of time, especially for the transportation of mineral materials, in the roller or roller often have material bonding, making the roller or roller local thickness increase, resulting in uneven force on both sides and cause runaway. The belt is affected by the lateral force of the pulley and the roller, if the installation position of both of them is offset, the belt conveyor in the process of running the belt is subjected to lateral force inconsistency caused by the deviation. Lateral force is affected by various factors, if the installation position of the bearing roller and the center line there is a large perpendicularity error or roller circumference and the center line there is a large perpendicularity error, it will cause the belt deflection, and in the roller, roller installation position deflection is obvious.

Roller

How to prevent runout

Reasonable adjustment of roller set

If the belt deflection occurs in the middle part of the belt conveyor, the method of adjusting the position of the roller group can effectively correct the belt deflection. In order to adjust the roller group more conveniently, the installation holes on both sides of the roller bracket can be designed as long holes, which can play an effective role in preventing the deviation due to the incorrect position or uneven distribution of materials, and at the same time, it can also play an effective role in correcting the deviation due to the tilting of the frame and vibration of the belt caused by the vibration of the equipment.

Roller

Adjust the position of the roller

If the belt runs out of alignment, the roller can be reasonably adjusted to achieve the purpose of correction. In the process of installing the roller, pay attention to the axis of the installation position of the roller and the center line of the belt machine to maintain good verticality, if the verticality error is too large to cause the belt to run off.

Adjustment of tensioning

Tensioning can be divided into mechanical tensioning and hammer tensioning according to the different forms. Mechanical tensioning usually refers to spiral tensioning, the use of such tensioning, no matter how to move the roller, we must pay attention to the roller axis and the longitudinal center line of the belt is completely perpendicular. If the form of heavy hammer tensioning, you need to pay attention to the redirection of the pulley not only with the belt length to maintain good verticality, but also with the gravity plumb line should be completely perpendicular, so as to ensure that the axis of the center line always maintain a horizontal state.

Installation of Aligning Roller Set

If the runout occurs in the middle of the belt conveyor operation, the installation of centering roller set can also be used to correct the runout. This method is located in the horizontal plane of the roller rotation generated by the transverse force to be used to the central axis as the core of the roller group frame rotation, so that the belt itself to the center of the movement, to play the role of centering.

Adjust the position of the material at the transfer point

Belt deflection by the reproduction point at the location of the material drop a great deal of influence, so in the process of installation we should try to expand the relative height between the two belt conveyor. At the same time, the size and shape of the funnel and the guide trough should be carefully studied and designed according to the actual situation, generally speaking, the width of the guide trough is two-thirds of the width of the belt is appropriate. In addition, it can also be taken to adjust the position and direction of the material landing on the belt, or set up a baffle plate to block the material, adjust the position of the material, so as to achieve the purpose of correcting the belt deflection.

Belt conveyor in the actual operation, run off is a common failure. When encountering this kind of failure, should be timely and effective correction. In addition, attention should also be paid to the installation of the various components of the belt conveyor as well as the daily maintenance and repair of the transmission system to ensure the efficient operation of the equipment.
