Hydraulic Cylinder Bushings

Principle of hydraulic bushing

Hydraulic bushing mainly realizes the movement of moving parts and the sealing of seals through the pressure of hydraulic oil. Hydraulic oil flows in the hydraulic cylinder along the gap between the bushing and the piston to push the piston movement; The hydraulic oil around the piston is effectively sealed in the gap between the bushing and the piston, playing a sealing role. Hydraulic bushing should also be designed to prevent the occurrence of oil immersion and plugging to ensure the normal operation of the hydraulic system.

Hydraulic bushing design principle is as follows:

1. Ring sealing principle: The ring sealing principle of the hydraulic bushing is realized by using the gap between its inner surface and the piston surface. Through the pressure of hydraulic oil, the inner surface of the bushing and the piston surface maintain a certain contact pressure, so as to achieve good sealing performance.

2. Friction resistance principle: The friction resistance principle of hydraulic bushing is to use the lubrication of hydraulic oil to reduce the friction and wear of the piston inside the bushing, so as to improve the life and operating efficiency of the hydraulic system.

3.support principle: The support principle of the hydraulic bushing is achieved through the gap between it and the piston. Driven by moving parts, the hydraulic oil flows through the gap between the piston and the bushing, and generates a supporting force, thus maintaining the stability of the system operation.

The working principle of the hydraulic bushing is one of the important factors to keep the hydraulic system running. In the hydraulic system, through fine design, manufacture and use, you can realize the efficient, stable and reliable operation of the hydraulic system.

Hydraulic bushing is widely used in hydraulic system such as hydraulic cylinder, hydraulic pump and hydraulic valve, and its application scope includes mechanical equipment, mining machinery, metallurgical equipment, construction machinery, aerospace and other fields.
