What is the importance of the exhaust device of the hydraulic cylinder?
Publish Time: 2024-07-22
In a complex hydraulic system, the hydraulic cylinder is an actuator, and its performance directly affects the stability and efficiency of the entire system. The exhaust device of the hydraulic cylinder is a key link to ensure the normal operation of the hydraulic cylinder.
When the hydraulic cylinder is first installed or restarted after a long period of disuse, a certain amount of air is often mixed into the system due to changes in the solubility of air in the oil and incomplete sealing of the pipe joints. These air bubbles exist in the oil in the form of bubbles, which not only reduce the compressibility of the oil, but also affect the movement smoothness and precision control of the hydraulic cylinder. When the bubbles enter the hydraulic cylinder with the oil, they will expand and burst rapidly under high pressure, causing shock and vibration, causing damage to the hydraulic cylinder and its related components.
At this time, the exhaust device of the hydraulic cylinder is particularly important. The exhaust device is usually designed at the highest point of the hydraulic cylinder or the position where air is easy to accumulate. Through a specific structure, air is allowed to be discharged from the system while preventing oil leakage. Before starting or during the operation of the Hydraulic cylinder, the air in the system can be effectively discharged by opening the exhaust device to ensure that the oil fills the entire Hydraulic cylinder and pipeline, thereby restoring the normal performance of the Hydraulic cylinder.
Therefore, regular inspection and maintenance of the exhaust device of the Hydraulic cylinder to ensure that it is unobstructed is of great significance to ensure the normal operation of the hydraulic system, extend the service life of the Hydraulic cylinder, and improve production efficiency and product quality. In actual application, operators should fully realize the importance of the exhaust device and strictly follow the operating procedures to perform exhaust operations to ensure the stability and reliability of the hydraulic system.
