Jun'an machinery explains the influence of driving wheel on hoist

Article source: admin release date: May 6, 2013

Lunan machinery explains to you Hoist The impact of unloading. In some mechanical failures, we will find a phenomenon called backflow. Especially for the elevator, which is used to transport materials, backflow is a very serious problem. It not only causes the output not to go up, but also increases energy consumption and idle power consumption. Military safety machinery is specialized in the production and manufacture of hoists. In view of this problem, today we will discuss the problem of hoist backflow and the influence of driving wheel set on elevator reflux.

Bucket type Hoist The backflow occurs in two parts: one is the process of lifting materials on the loaded branch; the other is unloading at the head. The former problem is simple, as long as the tension is adjusted to ensure the bucket camber within the allowable range; the latter problem is more complex, there are many factors affecting the unloading, one of which is the matching relationship between the driving wheel diameter and the running speed of the conveyor belt. The speed coefficient should be regarded as the main performance parameter of bucket elevator, although it is invisible on the surface. Its value not only indicates the unloading mode, but also quantitatively reflects the proportional relationship between the driving wheel diameter and belt speed. In order to ensure smooth unloading, the diameter of driving wheel shall meet the following formula:
Centrifugal discharge: D = (0.185-0.204) V2;
Mixed discharge: D = (0.205-0.286) V2;
Gravity discharge: D = (0.287-0.612) v2.
