Manhart What is the reason for the hydraulic system failure of the oil electric servo pump controlled bending machine?

The main reasons for the hydraulic system failure of the oil electric servo pump controlled bending machine include the following aspects:
1. * * Electrical system issues * *:
-Power line faults, such as damage, short circuits, etc., may cause interruption or instability of hydraulic system control signals.
-Electrical component failures, such as damaged or malfunctioning relays, switches, sensors, etc., may directly affect the control accuracy and stability of hydraulic systems.
-Control system software issues, such as software defects or outdated versions, may lead to system control logic errors or performance degradation.
2. Improper maintenance of hydraulic system:
-The hydraulic system has not been cleaned and maintained for a long time, resulting in the accumulation of oil and impurities, which may block the oil circuit or affect system performance.
-The filters in the system were not replaced or cleaned in a timely manner, resulting in oil contamination, affecting the performance of hydraulic oil and the stable operation of the hydraulic system.
-Improper setting of parameters such as pressure and flow in hydraulic systems, or malfunction of regulators, may lead to abnormal system operation.
3. * * Poor oil management * *:
-The use of inappropriate hydraulic oil or poor oil quality may lead to increased system wear and high oil temperature rise.
-Failure to replace hydraulic oil in a timely manner, aging or contamination of the oil, may lead to a decrease in system performance or malfunction.
4. * * Seal failure * *:
-Damaged or aged seals in hydraulic cylinders, pipelines, and other areas may cause internal fluid leakage in the system, thereby reducing system efficiency and affecting normal operation.
-Improper installation or loose fastening of seals may also lead to leakage issues in the system.
5. * * Mechanical component failure * *:
-Damaged or worn components such as hydraulic cylinders, pumps, and motors may cause the hydraulic system to malfunction or decrease performance.
-Loose or damaged connections, fasteners, etc. in the system may cause leaks and malfunctions.
6. * * Improper operation * *:
-Failure or improper operation by operators may result in abnormal loads or impacts on the hydraulic system, leading to malfunctions.
7. * * Environmental factors * *:
-The working environment is harsh, such as high temperature, high humidity, and excessive dust, which may affect the normal operation of hydraulic systems and the lifespan of components.
In summary, the causes of hydraulic system failures in oil electric servo pump controlled bending machines are diverse, and comprehensive prevention and maintenance are needed from multiple aspects such as electrical system, hydraulic system maintenance, oil management, seals, mechanical components, operation, and environment. Regular inspections, timely replacement of worn parts, maintenance of system cleanliness, and proper use of oil can effectively reduce the incidence of hydraulic system failures.
