What are the common causes of hydraulic leakage in the bending machine of Manhart (Guangdong) CNC Machine Tool Co., Ltd?

There are various common causes of hydraulic leakage in the bending machine, mainly including the following aspects:
1. * * Seal failure * *: Seals (such as O-rings, gaskets, etc.) are key components to prevent hydraulic leakage. If the seal is aged, worn, damaged, or improperly installed, it may lead to leakage.
2. Loose or damaged pipe joints: Loose or damaged pipe joints can also cause hydraulic leakage.
3. * * Hydraulic cylinder and pump damage * *: Damage to the piston rod and seals of the hydraulic cylinder, pump shaft seals, and other components may cause hydraulic leakage.
4. * * Excessive pressure * *: If the pressure setting of the hydraulic system is too high, exceeding the bearing range of the seals and pipe joints, it may also cause leakage.
5. * * Excessive oil temperature * *: Excessive oil temperature can cause a decrease in the viscosity of the oil, reduce the sealing effect, and increase the risk of leakage.
6. * * Design and Manufacturing Defects * *: If there are defects in the design or manufacturing of hydraulic systems, such as unreasonable pipeline layout, improper sealing structure design, etc., it may also lead to leakage.
7. * * Vibration and Impact * *: The bending machine may generate vibration and impact during operation, which may cause the sealing components to loosen or be damaged over a long period of time, leading to leakage.
In order to reduce the occurrence of hydraulic leakage, the hydraulic system should be regularly inspected and maintained, aging or damaged seals and pipe joints should be replaced in a timely manner, oil temperature should be maintained within the normal range, the pressure setting of the hydraulic system should be reasonable, and the equipment should be avoided from enduring excessive vibration and impact for a long time. At the same time, in the design and manufacturing process, the sealing and reliability of the hydraulic system should also be fully considered to reduce the risk of leakage.
