Manhart How to judge whether the hydraulic system of the combined punching and shearing machine is good?

To judge whether the hydraulic system of the combined punching and shearing machine is good, you can do it from the following aspects:
I. **System performance indicators**
1. **Pressure stability**: Check whether the hydraulic system can maintain a stable pressure output during operation and whether it meets the design requirements of the equipment.
2. **Flow stability**: Observe whether the flow of the hydraulic system is stable and has no abnormal fluctuations to ensure that the system can continuously and stably supply hydraulic oil.
3. **Temperature control**: The oil temperature of the hydraulic system should be kept within the normal range during operation. Too high or too low oil temperature may affect the performance and life of the system.
II. **System safety**
1. **Leakage check**: Regularly check whether there are leaks in hydraulic pipelines, joints, seals, etc. to ensure that the system is well sealed and avoid failures and safety hazards caused by hydraulic oil leakage.
2. **Overload protection**: Check whether the system has an overload protection function to ensure that it can automatically shut down or take other protective measures when the system is overloaded to avoid equipment damage or accidents.
3. **System reliability**
1. **Noise observation**: Pay attention to whether the hydraulic system makes abnormal noise when working, such as whether the noise of hydraulic pumps, motors and other components is too loud, which may be related to the wear or failure of the internal components of the system.
2. **Operation stability**: Observe whether the hydraulic system is stable during operation, without abnormal vibration or impact, which may be related to the balance state inside the system or the wear of the components.
4. **System maintenance and care**
1. **Oil inspection**: Regularly check the cleanliness and quality of the hydraulic oil, observe whether there is pollution or deterioration, and replace the contaminated hydraulic oil in time.
2. **Filter element replacement**: Replace the filter element of the hydraulic system according to the prescribed cycle to ensure the good filtering effect of the system and avoid impurities entering the system and causing damage.
5. **Environmental adaptability**
1. **Adapt to the working environment**: The hydraulic system should be able to adapt to the working environment of the punching and shearing machine, such as temperature, humidity, dust and other factors, to ensure that the system can operate stably in various environments.
VI. **System monitoring and diagnosis**
1. **Monitoring tools**: Use professional monitoring tools to monitor and diagnose the operating status of the hydraulic system in real time, and promptly discover and solve potential problems.
By comprehensively checking and evaluating the above aspects, it is possible to comprehensively judge whether the hydraulic system of the combined punching and shearing machine is good. At the same time, in order to ensure the stability and reliability of the hydraulic system, it is recommended to perform regular maintenance and inspections to promptly discover and solve potential problems.
