The rapid diagnosis method for simple faults of hydraulic presses is the most common method used in the hydraulic press machine industry at present. It relies on the experience accumulated by the maintenance personnel in the long-term practice, and uses simple instruments to objectively adopt the method of watching, listening, etc. according to the fault phenomenon of the hydraulic system. Methods To understand the working conditions of the hydraulic press, analyze and diagnose, so as to determine the cause and location of the failure.
2. Look at the actual working conditions of the hydraulic system, and observe whether there are problems with the system pressure, speed, oil, leakage, vibration, etc.
3. Listen carefully to the sound of the hydraulic system, such as impact sound, pump noise and abnormal sound, to judge whether the hydraulic system is working normally.
4. Determine whether the working conditions of the moving parts of the hydraulic press are normal according to the temperature rise, vibration, crawling and the tightness of the connection.
In a word, the method of rapid fault diagnosis of hydraulic press is only a simple qualitative analysis, which not only depends on the maintenance personnel to be proficient in understanding the working principle of hydraulic press and the maintenance knowledge accumulated in long-term practice, but also depends on whether the operator of the machine The correct steps to use the hydraulic press have a great relationship. Generally speaking, 80% of the failure of the hydraulic press system has a great relationship with the pollution of the hydraulic oil. The pollution can easily cause the hydraulic components to malfunction. It should be considered in the analysis.
