What is the simple fault diagnosis method for the automatic cutting machine?
The simple fault diagnosis method of the cutting machine is the most common method currently adopted. It relies on the personal experience of the maintenance personnel to use the simple instrument to solve the failure of the hydraulic system, and objectively use the methods of asking, watching, listening, touching and smelling. The system works, analyzes, diagnoses, and determines the cause and location of the fault. The specific practices are as follows:
1) Ask the equipment operator to find out the equipment operation status. These include: whether the hydraulic system works normally; whether the hydraulic pump is abnormal; the time and result of the cleanliness of the hydraulic oil; the cleaning and replacement of the filter; whether the hydraulic components are adjusted before the fault occurs; whether the sealed components are replaced; What are the abnormalities in the hydraulic system before and after; what problems have occurred in the system in the past, how to eliminate them, etc., need to understand one by one.
2) Look at the actual condition of the hydraulic system of the cutting machine and observe whether there are problems with the system pressure, speed, oil, leakage, vibration, etc.
3) Listen to the sound of the hydraulic system of the hydraulic cutting machine, such as: impact sound; pump noise and abnormal sound; determine whether the hydraulic system works normally.
4) Touch the temperature rise, vibration, creep and the tightness of the joint to determine whether the working condition of the moving parts is normal.
In short, the simple diagnosis method is only a simple qualitative analysis, which has a wide range of practicality for quick judgment and troubleshooting.
