In the hydraulic system, the seal is one of the key components that play an important role. How to choose the right seal can not only ensure the normal operation of the hydraulic system, but also extend the service life of the seal. It is a knowledge point that every hydraulic system maintenance engineer needs to understand. This article will focus on the selection of O-ring in the hydraulic system.
In the hydraulic system, the seal is one of the key components that play an important role. How to choose the right seal can not only ensure the normal operation of the hydraulic system, but also extend the service life of the seal. It is a knowledge point that every hydraulic system maintenance engineer needs to understand. This article will focus on the selection of O-ring in the hydraulic system.
First, the basic principle of O-ring
O-ring seal is a kind of seal widely used in hydraulic system. Its structure is circular, the cross section is right round, has good elasticity and plasticity, can withstand greater pressure in the hydraulic system, to achieve the role of sealing.
Second, the O-ring seal selection principle
1. Selection of materials
The material of the O-ring seal should be selected according to the type of medium, the use of temperature and pressure and other factors. Generally speaking, silicone rubber and butyl rubber are commonly used materials in hydraulic systems, and they have good elasticity and wear resistance.
2. The choice of size
The size of the O-ring seal should be selected according to the installation space and working pressure of the seal. When selecting the size, it is also necessary to consider the compression deformation of the seal to ensure the sealing effect.
3. Requirements for surface quality
The surface quality of the O-ring shall ensure smoothness and avoid burrs, cracks and other defects to ensure the sealing effect.
Three, O-ring seal installation points
1. Before installation, check the size and surface quality of the seal to avoid defects.
2. When installing, be careful not to damage the surface of the seal to avoid affecting the sealing effect.
3. The installation should be adjusted according to the compression deformation of the seal to achieve a good sealing effect.
IV. Precautions for Maintenance of O-ring Seal
1. In the hydraulic system, the O-ring seal is susceptible to corrosion and wear of the medium, so the use of the seal should be checked regularly. If severe wear or aging is found, it should be replaced in time.
2. In the hydraulic system, the service life of the O-ring is related to the use environment. Therefore, the impact of excessive friction and high temperature on the seal should be reduced as much as possible to extend the service life of the seal.
In short, choosing the right O-ring has an important impact on the normal operation and service life of the hydraulic system.
