subject: Improved Belt Ensure Reliable Operation [print this page] Drum is the main belt conveyor components, the service life of roller conveyor seriously affected the normal operation and production.
The use of a coal mine in Gansu Province DSJ120-belt conveyors, work, a bend of the web seam roller several times and multiple cracks, the worse a web cracking phenomenon, which has seriously affected the production. In the detection and repair, from the force structure and drum-pronged approach, the analysis of the reasons for cracking, and the structure and process in an improved, improving methods of other belt drum machine maintenance and repairs also have reference.
Drum can be divided into force by driving drum and bend drum, drum drive transmission is based on the principle of friction, will drive organic link with the conveyor belt to complete the energy transfer between the two tasks, and ensure the reliable operation of the conveyor . Bend roller conveyor system is used to change the direction of the farewell, due to a change in direction from the conveyer belt carrying the take-up pressure
An increase of holes to eliminate thermal expansion cracking.
b. In a roller inside the vertical layout of the axial direction of strengthening the roundabout, to enhance the strength of drum.
c. welded steel castings and steel structure to combine structural welding, welding to reduce stress, improve their overall strength.
d. bearing modified in the cylinder, the overhaul will no longer shell and the disintegration of axis, a decrease of the cylinder and shaft damage, while providing a convenient for maintenance.
e. drum increase the thickness of the plate and improve manufacturing quality and ensure drum intensity.
strengthen safeguard and enhance drum life, such as the workplace kept clean and ensure that cooling conditions; does not allow roller conveyor belt along the slippery, found an immediate relaxation of tension.
