Five reasons for the excessively low speed of the direction-changing drum

2017-07-31View Original

Thread Content

Many users have reported that when using deflection drums, the rotation speed might be too low. So what are the reasons for this phenomenon? Let’s take a brief look at them together. 1. Human factors: A considerable number of users, due to damage to the motor originally fitted with the direction-changing drum, arbitrarily install another motor to drive it, which results in an excessively low speed. 2. Wear of the conveyor belt: Many large deflection drums use belt drives; due to long-term use, the conveyor belts wear out and become loose, resulting in slippage and thereby reducing the speed of the deflection drum. 3. Improper installation, such as an excessively small distance between the centers of the two pulleys or the axes not being parallel enough, the tight side of the conveyor belt being installed on the upper side which results in a too small wrap angle, calculation errors regarding the diameters of the two pulleys, and a large eccentricity between the axes of the redirecting drum in coupling-driven systems, can all cause changes in the speed of the redirecting drum. 4. Mechanical failures of the deflection drum itself. Loose fastening nuts on the impeller and the reaction tank shaft, or deformation and bending of the reaction tank shaft, can cause the impeller to shift significantly, resulting in direct friction with the reaction tank body; or damage to the bearings, all of which can reduce the speed of the direction-changing drum. 5. Repairs to the power engine are not recorded; the direction-changing drum loses its magnetism due to burned-out windings. Changes in the number of winding turns, wire diameter, or wiring method during repairs, or failure to completely eliminate faults during repairs, can also cause a change in the speed of the direction-changing drum. That’s all for the introduction to the five reasons that cause the speed of the redirecting drum to be too low. By understanding these reasons, they will surely be of greater help to us in future use. That’s all there is to say regarding this topic.
