132HC Mast Section Tower crane fault classification, according to the speed of the occurrence of the fault is divided into several categories?

06-12-2019

The state that the tower crane equipment loses the specified performance is called tower crane failure. For example, the bearing temperature exceeds the specified value; the lubricating oil consumption increases; the vibration and noise of the machine increases; the deformation of the parts exceeds the allowable range, or even breaks; the clearance between the bearing shells increases, and the fasteners loosen, etc. The failure of tower crane can be attributed to the damage of its parts and the damage of the relationship between the parts. In this paper, according to the classification of tower crane faults, which kinds of tower crane faults are classified according to the speed of occurrence? Do the following brief.

Fault classification of tower crane




(1) gradual failure




Its characteristic is that the probability of fault occurrence is related to service time. The longer it is used, the greater the probability of failure. This kind of fault is closely related to material, wear, corrosion, fatigue, temperature and other processes of parts. Most tower crane failures are of this type. Once the fault occurs, it means the end of the effective life of the equipment or the equipment must be overhauled. This kind of fault can be predicted by different monitoring methods.

(2) sudden failure




It is characterized by the contingency of fault occurrence, which has nothing to do with the service time of the equipment. Therefore, this kind of display is difficult to measure. For example, the tooth or shaft of the roller is broken due to falling steel parts during the operation of the double tooth roller crusher; the bearing bush of the high-pressure centrifugal blower is damaged due to the sudden interruption of lubricating oil, etc.




(3) compound fault




Its characteristic is that the time of fault occurrence is random and uncertain, which is independent of the time of equipment use, and the speed of damage process of equipment parts is a function of time. This kind of fault has the characteristics of the above two kinds of faults. For example, the excessive load is caused by falling into the super hard object in the forehead crusher, and the safety plate is not protected from fracture due to the material problem, resulting in the crack of the moving head. With the continuous use of the equipment, the crack propagation causes the fracture accident of the moving head.
