Manhart How to quickly diagnose and solve hydraulic system faults in oil electric servo pump controlled bending machines?

To quickly diagnose and solve hydraulic system faults in the oil electric servo pump controlled bending machine, the following steps can be followed:
1、 Fault diagnosis
1. * * Observation method * *:
-Firstly, observe the pressure value indicated by the pressure gauge to determine if there is any abnormal situation. If the hydraulic indicator shows a low value or there are obvious signs of leakage, it can be preliminarily judged that there may be a malfunction in the hydraulic cylinder.
-At the same time, observe whether there are any signs of liquid leakage in the hydraulic cylinder, which may be accompanied by certain sounds.
2. * * Instrument diagnostic method * *:
-If obvious faults cannot be found through observation, or if certain system faults cannot be detected through observation, instruments need to be used for diagnosis.
-Commonly used instruments include particle X-ray flaw detectors and X-ray imagers. These instruments can diagnose and detect internal faults in hydraulic systems, such as misalignment or wear, by sending high-energy particles.
2、 Troubleshooting
1. * * Hydraulic system malfunction * *:
-For hydraulic system malfunctions such as insufficient pressure, oil leakage, and jamming, it is necessary to first inspect the hydraulic system itself, including the hydraulic pump, hydraulic cylinder, oil circuit, and other parts.
-If insufficient hydraulic oil or high hydraulic oil temperature is found, hydraulic oil should be added or replaced in a timely manner.
-For leakage issues, the sealing components should be checked for integrity, and if there are any problems, they should be replaced in a timely manner.
2. * * Electrical system malfunction * *:
-If there is an electrical system malfunction in the equipment, such as an insensitive switch or damage to electrical components, the power circuit and electrical components should be checked first to ensure they are in good condition.
-If necessary, the electrical system can be repaired or damaged components can be replaced.
3. * * Mechanical component wear * *:
-For faults caused by mechanical component wear, regular maintenance should be carried out, including replacing worn parts and strengthening lubrication.
-If minor faults such as cracks or small holes are found in the hydraulic cylinder, welding can be used for repair.
4. * * Other issues * *:
-If there are safety issues with the equipment, such as the lack of emergency stop function, the corresponding safety equipment should be installed or repaired as soon as possible.
-In addition, during the process of resolving faults, attention should also be paid to recording information such as fault phenomena, handling processes, and replaced components for subsequent analysis and summary.
3、 Summary and Prevention
1. * * Summary and Analysis * *:
-After resolving the fault, it is necessary to summarize and analyze the cause and handling process of the fault, identify the root cause of the fault, and develop targeted preventive measures.
2. * * Preventive measures * *:
-Based on the summary and analysis results, corresponding preventive measures should be formulated, such as strengthening the daily inspection of equipment, regularly replacing hydraulic oil and filter elements, and strengthening lubrication.
-At the same time, strengthen the training and management of operators to ensure that equipment is used and maintained correctly.
Through the comprehensive application of the above steps, faults in the hydraulic system of the oil electric servo pump controlled bending machine can be quickly diagnosed and solved, and corresponding preventive measures can be taken to reduce the occurrence of faults and extend the service life of the equipment.
