Conveyor belt! Points for attention in starting and transporting
1. In order to ensure the necessary starting energy torque, the current when the power generator is started is 6-7 times larger than the current during rated operation. It is necessary to ensure that the power generator will not be burnt due to overheating due to the impact of the current, and the power grid will not cause excessive voltage due to high current. Down, which requires the initiation process of the power idea to be as fast as possible, and the acceleration of the rotor. So that the initiation process does not exceed 3-5s, the method of increasing the power of the electric motor was adopted in the early years, which is also possible for small and short belt conveyors.
2. The conveyor belt is a kind of viscoelastic body. In the unsturdy stage of the large belt conveyor, the traction force and inertial force exerted by the driving equipment on the conveyor belt will be transmitted, superimposed, reflected in the belt at a certain wave speed, and increased. The influence of other factors above will cause variable stress changes in the conveyor belt. If the instantaneous peak stress exceeds the allowable value, the conveyor belt will be damaged or even cracked, or the rollers and rollers will be damaged, which requires the smallest possible amount. Initiate acceleration to descend the shock at launch.
Analysis and treatment of the defects of conveyor belt roller blockage
There are many reasons for the blockage of the conveyor rollers. Let’s start with the methods to avoid blockages: strict implementation of operating procedures, no-load start, no-load parking, and uniform feeding. It is fair to choose various technical parameters of the conveyor roller, assuming that the speed of the slow conveyor roller cannot be too large. It is necessary to enlarge the discharge port or lengthen the end of the trough to deal with the problem of poor discharge and late discharge, so as to avoid end blockage. An anti-blocking valve is set on the discharge end cover. Due to material deposition, the anti-blocking door should be opened and the material entering the conveyor should be cleaned up to avoid large impurities or fibrous impurities entering the machine and causing blockage. It is necessary to reduce the lateral size of the surrounding suspension bearing as much as possible to reduce the possibility of material blocking when the material passes through the surrounding bearing. When installing the silo level sensor and clogging sensor, it is necessary to complete automatic control and alarm. When using the conveyor belt roller, the phenomenon of blockage will be greatly reduced or even not generated, so the production and use are unobstructed.
