A simple fault diagnosis method
(4) The working state of the moving parts is judged by the temperature rise, vibration, crawling and the tightness of the joints.
B hydraulic system schematic diagram analysis method
According to the principle diagram of the hydraulic system of the color coating board, this paper analyzes the faults of the hydraulic transmission system, finds out the parts and causes of the faults, and puts forward the methods to eliminate the faults of the color coating board. Combined with the action cycle table, it is easier to analyze and judge the fault.
C other analytical methods
When the hydraulic system breaks down, the logic analysis is carried out according to the principle of the hydraulic system or the cause and effect analysis is used to check one by one. Finally, the fault location is found out, which is to find out the fault with the method of logic analysis. In order to facilitate the application, Chen diagnosis experts designed logic flow chart or other charts to judge the fault logically, which provides convenience for fault diagnosis.
