The importance of hydraulic and sealing technology

There are two main types of piston seal technology.

　　First, the corresponding part of the seal is squeezed under a specific pressure with the help of a specific transport medium. In this way the corresponding radial force is generated, which produces the sealing effect. However, its sealing lip is prone to wear and damage to the cylinder wall, which does not guarantee the sealing effect.

　　Secondly, a rubber seal is required, which generates radial pressure through the elastic deformation of the seal to achieve the sealing effect. The sealing principle is to make the compound seal deform elastically by applying a preload corresponding to the seal ring during the piston movement, and then generate radial force to make the compound seal in close contact with the cylinder wall to effectively achieve the sealing effect. However, during certain work processes, a large amount of heat is generated due to friction, which accumulates in the seal ring, making it difficult to release the heat in time, the rubber ring ages faster, and the life of the corresponding seal is shortened.

　　Hydraulic systems can greatly improve the braking system, basic operation and steering functions of large machinery and equipment. Seals play a decisive role in the reliable operation of hydraulic equipment.

　　In order to ensure the safe and stable operation of petroleum machinery and equipment, it is necessary to ensure the safety and stability of mechanical hydraulic equipment, and the sealing performance of petroleum machinery and equipment must be ensured.

　　In this process, if the sealing performance of petroleum machinery is weak, the hydraulic performance and overall mechanical performance of petroleum machinery will become increasingly poor.

　　Oil leakage and sealing problems in oil machinery lead to waste of resources and environmental pollution. The internal leakage and sealing problems in oil machinery can lead to serious internal damage and shorten the service life of oil machinery.

　　Therefore, in order to give full play to the important role of hydraulic performance of petroleum machinery, it is necessary to improve the sealing performance of petroleum machinery and equipment by applying effective hydraulic sealing technology to petroleum machinery in a reasonable way.
