If the oil film is too thick and the impact pressure of the oil is not allowed to abject the oil, the appropriate hydraulic oil film is quite important. Therefore, in order to better ensure the operation of the seal and the operation of the working life, the process of the hydraulic seal should be used to maintain lubrication.

Hydraulic seals are selected in the hydraulic sealing system, and the seal design is extremely important, which is manifested in the consolidated hydraulic sealing system has excellent sealing performance. Hydraulic seals are selected in the hydraulic system, and the common hydraulic seals have an extruded O-type seal, a Y-shaped seal, a V-shaped seal, a U-shaped seal, and a lip seal.

For example, in a special field environment, we can use dust circles; usual working environment we can use Strace or Grid seals. The sealing member needs to be checked, cylinder, and the relevant surface of the mounting guide sleeve before installation, ensuring cleaning, no burr, no edge. In the static seal, in order to prevent the O-ring from being extruded, the gap between the sealing plane can be reduced,Mechanical oil seal Manufacturers and a material having a higher hardness can be selected.

Therefore, in order to better ensure the operation of the seal and the operation of the working life, the process of the hydraulic seal should be used to maintain lubrication. Rational sealing process.The purchase problem of hydraulic seal material must be combined with the specifications of the seal, and whether it is paired with the model of the mechanical sealing system, and combines the perfect seal.

The basis of the engineering hydraulic seal and the relationship between hydraulic oil film? Foshan part tells you that almost all of the dynamic sealing operations are inseparable from good lubricating fluid (hydraulic oil) oil lubrication to the performance and work life of the seal model specification.

Therefore, in order to better ensure the operation of the seal and the operation of the working life, the process of the hydraulic seal should be used to maintain lubrication. When the part is to operate in the hydraulic cylinder, as the system pressure increases, the pressure liquid enters the hydraulic cylinder, the O-type rubber seal is extruded under the pressing of the pressure liquid, and is extruded on the side of the sealing trench, due to compression

The elasticity variable, the rubber seal is elastic extruded slide rings produced by elastic deformation, thereby tightly attaching the slide seal to the surface of the seal, forming additional contact stress, this contact stress increases with the liquid pressure Big,Industrial crankshaft oil seal Manufacturers and generate a sealing effect together with the initial contact stress to achieve a better sealing effect.

When the hydraulic cylinder is working, the pressure liquid acts on one side of the Streen, and the sealing edge of the special shape has a steep contact pressure gradient on the high pressure side, and at the low pressure, the two-step contact pressure gradient is produced, thereby ensuring the piston.

The intermediate pressure formed in series is configured. But if the oil film formed by the oil is too thin, what will happen? The seal of the seal at this time is in direct contact with the protruding surface due to the thickness, the hardness is in direct contact with the projection surface, and the hardness is wear the seal section, resulting in unnecessary sealing leakage
