1. Calculate the peak value of conveying driving tension and its occurrence conditions during the operation of the conveyor. The peak value of the conveying driving tension is usually several times or even more than ten times of its normal operating tension, and the tension value calculated according to the previous static design method is much smaller than the actual value, so the safety factor can only be increased to ensure the safe operation of the conveyor. In the absence of reliable analysis tools, the safety factor determined by empirical methods is often too large, which will inevitably lead to rising costs and waste of investment.
2. The vibration characteristics of the conveyor belt in operation are analyzed. Vibration is the main reason that leads to the increase of conveyor driven tension, and it is also the culprit that causes the belt breaking accident. To find out its rules is of great significance to effectively control the conveyor driven tension.
3. The influence of boundary conditions on the vibration of conveyor belt is studied. The boundary conditions of conveyor belt refer to all internal and external conditions that affect the dynamic characteristics of conveyor belt, such as driving device, tensioning device, idler, load, etc. The influence of the change of these boundary conditions on the vibration is analyzed and studied, and the optimal form of the boundary conditions for optimizing the vibration characteristics of the conveyor belt is found; The comprehensive index of performance and economy is optimal.
At present, there are many kinds of trams for ore transportation in domestic mines, and large and medium-sized mines tend to use bottom dump and bottom side dump trams for transportation. Compared with other types of tramcars, these two types of tramcars can realize continuous loading and unloading
Good morning, young friends! Next, the small editor is ready to explain the relevant contents of the single hydraulic prop for the small friends. The small friends are also deeply impressed with the single hydraulic prop. I still hope that this explanation will bring some gains to my friends1. For n
In order to make the hydraulic acrow props work stable, give full play to the efficiency of the equipment, and extend the service life, in addition to strictly complying with the operating procedures, it is necessary to strengthen daily maintenance.Precautions for maintenance and management of singl
