Vibrating screens are important for technological innovation. The new vibrating screens are more in line with the needs of customers: vibrating screens are subject to various potential damage threats during use, such as:
(1) Internal energy (various vibrations, loads, temperatures, etc.) related to mechanical operation and the work of various agencies;
(2) The role of the energy of the surrounding medium, including the role of the operator performing the task, the repairman and the environmental conditions;
(3) Latent energy concentrated in mechanical materials and components during manufacturing and assembly.
These damages mainly exist in the form of mechanical energy, thermal energy and chemical energy of the vibrating screen itself. When the energy reaches a certain value, it will inevitably lead to the occurrence of harmful processes, causing changes in the initial performance and state of the mechanical parts. When the power and speed are moving, each other will produce a harmful friction process, and the result of the friction will cause the wear of the mating pair to occur, and the movement of the mating pair may change.
With the development of these harmful processes, the first part will cause damage to the parts, which are manifested by the occurrence of wear, cracks, deformation, fatigue, corrosion, etc. The occurrence of damage will change the structural parameters of the mechanical parts, such as Some dimensional tolerances, geometric tolerances, and changes in fit clearances. Changes in structural parameters in turn lead to changes in mechanical function output parameters, such as changes in mechanical output power, speed, and the like. As the degree of damage to the vibrating screen is further expanded, the structural parameters of the mechanical components gradually exceed the allowable values. If the structural parameters of the mechanical parts of the vibrating screen exceed the allowable value, and the output parameters of the function do not exceed the allowable limit range, it can be considered that the machine has a potential failure, and the corresponding state is an abnormal state, which should be eliminated by maintenance; If the function output parameter exceeds the allowable value after the structural parameter exceeds the limit, it is considered that the mechanical fault has occurred, and the corresponding state is the fault state. At this time, the corresponding fault should be eliminated by repair.
Therefore, any vibrating screen will gradually wear out with the passage of time, and finally it will not operate normally. In order to improve the service life of the machine, it is necessary to continuously innovate in technology and continuously apply new technology to the development of vibrating screen. In order to develop a vibrating screen with more efficiency and longer service life.
