Problems to be considered in the installation of coal mine belt conveyor
16,Dec,2019Visits: 8

  The installation quality of the coal mine belt conveyor plays a key role in the success of the commissioning. Therefore, it is necessary to not only make careful preparations for commissioning, but also make preparations for the unexpected situation during commissioning and the commissioning of the conveyor deviation and distortion. The belt conveyor manufacturer will summarize the problems that need to be considered during the installation and commissioning of the coal mine belt conveyor?

  

  1. The rigidity value of the conveyor belt is too large: the rigidity value of the conveyor belt is too large, which exceeds the design value, so the rigidity resistance and the pipe forming resistance are too large, resulting in the design power less than the load power. Solution: through technical research, we can understand the manufacturing parameters of conveyor belt and analyze whether the parameters are reasonable.

  

  2. Deviation adjustment: due to its structural characteristics, there are two kinds of deviation adjustment and distortion.

  

  3. The soft start protection current is set too low. According to the actual situation of the power grid of the thermal power plant, the protection current can be increased properly;

  

  4. The friction resistance of six deformation idler group is too large. In view of this problem, it is necessary to carefully check the installation of idler group and adjust it;

  

  5. When the conveyor belt in the middle bearing section and return section is twisted, a special adjustment pin with a diameter of 5mm can be used to adjust the twist by adjusting the roller position on the window type idler group. When the conveyor belt is to be adjusted to a, an adjustment pin shall be added at a; when the conveyor belt is to be adjusted to B, an adjustment pin shall be added at B.

  

  6. When the transition section deviates, its adjustment direction: when the conveyor belt deviates to direction a, about five groups of idler groups in front and back of the deviation section shall be adjusted to direction a; when the conveyor belt deviates to direction B, the idler group shall be adjusted to direction B.

  

  7. Adjust the direction when the head and tail deviate. When the conveyor belt deviates from direction a, adjust the head wheel to direction a; when the conveyor belt deviates from direction B, adjust the tail wheel to direction B.
