V-shaped sealing package mainly plays the following roles in mining machinery and equipment accessories:
Axial pressureless seal: V-shaped sealing ring is an axial elastic rubber sealing ring, which is mainly used for pressureless sealing of rotating shaft to prevent internal grease or oil from leaking out.
Compensation for tolerance and angle deviation: the sealing lip of V-shaped sealing ring has good activity and adaptability, which can compensate for large tolerance and angle deviation and ensure sealing effect.
Prevent external invasion: V-shaped sealing ring can not only prevent internal grease or oil from leaking out, but also effectively prevent external splash or dust from invading the equipment.
Self-sealing function: in the free state, the outer diameter of the lip of the V-shaped sealing ring is larger than the inner diameter of the packing cavity, and the inner diameter of the lip is smaller than the outer diameter of the piston rod, which has certain deformation after assembly. This deformation produces pressure at the contact part, and even if no pressing force is applied, the lip can seal a certain internal pressure and play a self-sealing role.
Adaptability to high pressure and high temperature environment: V-shaped sealing ring is suitable for harsh working conditions such as high pressure, high temperature and corrosive medium, with good sealing performance and long service life.
Multi-ring overlapping use: V-shaped sealing rings can be used by overlapping several times, and the sealing performance is improved with the increase of overlapping number. At the same time, better sealing effect can be obtained by adjusting the pressing force.
Prevent dirt from invading: V-shaped sealing ring is usually used for dust-proof sealing to prevent external dirt from invading the equipment.
Suitable for high-speed movement: V-shaped sealing ring is suitable for high-speed movement sealing, such as oil cylinder piston sealing system, with a wide working speed range.
