The hydraulic seal specification structure is a self-sealing structure, which is easy to adjust on the compressive material, but the frictional force on the hydraulic mechanical equipment work cannot be determined and cannot be changed according to the change of the working pressure.
1. If it is a v-type hydraulic seal specification structure, it is a one-way sealing element made of low-stiffness flexible material. The size of the working seal is determined by the pressure value. Therefore, the frictional force at the time of low pressure is working in a large state.
2. If the u-type hydraulic seal specification structure is adopted, the u-type sealing material is a polymer elastomer material, and the rubber expansion body is increased to ensure the contact surface with the sealing bracket, and the friction is not caused in the working operation. Bit.
Third, the O-type hydraulic seal specification structure can work with the v-shaped groove, and the contact surface and friction degree will increase due to the increase of pressure. The hydraulic O-type seal has the advantages of a rectangular seal ring and a U-shaped seal ring, high pressure and The friction surface increases rapidly with increasing pressure.
Fourth, the rectangular section of the hydraulic seal structure, suitable for high-elastic material manufacturing is a suitable component of static seal and dynamic seal.
Because the U-shaped hydraulic seal and the V-type hydraulic seal structure only seal in one direction, it must be used in pairs to seal the effect, and pay attention to the assembly configuration. If the liquid between the pair of seals cannot be discharged smoothly, it is easy to cause the pressure and friction of the equipment to rise, and then the heat of the working temperature also rises, increasing the working load of the seal.
