how to maintain the hydraulic cylinder

2023-10-30

To prevent corrosion and rust, it is important to protect the piston of the hydraulic cylinder. As the piston extends outside the cylinder during operation, it is exposed to oxides and acid gases that can cause corrosion. Applying an appropriate amount of grease to the piston helps prevent corrosion and rust. This protective measure is crucial as a corroded or rusted piston can break during operation, leading to potential failures or accidents.
Regular maintenance of the hydraulic cylinder involves opening the cylinder and changing the hydraulic oil. Over time, foreign matter can enter the cylinder, increasing friction and causing damage to the components. Additionally, hydraulic oil has a limited lifespan and can become degraded or contaminated over time. If the oil is not changed periodically, it can lead to internal damage or corrosion within the hydraulic cylinder. To address these issues, it is necessary to open the cylinder, remove any foreign matter, and replace the hydraulic oil with fresh, clean oil.
Controlling the working speed of the hydraulic cylinder is crucial for its longevity. Excessive speed can negatively impact the cylinder's service life. To achieve optimal speed control, it is recommended to equip the hydraulic cylinder with a buffer device. The buffer device helps regulate the working speed, ensuring it stays within the ideal range of around two meters per second. This not only protects the hydraulic cylinder but also enhances safety during operation, prolonging its overall service life.
