What Is The Component Of A Mechanical Seal?

What is the component of a mechanical seal?

What is the component of a mechanical seal? What are the components of mechanical seals? Mechanical seals What are the processes that you use to describe the following?

    1. The side collisions (moving and static rings) adhere to the sealing surface closely to prevent the leakage of the medium. The dynamic and static rings are required to have outstanding wear resistance, the moving ring can move axially, and the wear of the sealing surface is actively compensated, so that it is excellently attached to the stationary ring, and the stationary ring has buoyancy and plays a buffering effect.

    2. elastic components (spring, corrugated plate, serpentine sleeve, etc.) mainly from the compensation, pre-tightening and buffering effect, but also on the sealed end face to produce a reasonable pressure factor. It is required to always insist on flexibility to overcome the conflict between the auxiliary seal and the transmission, and to initiate the effect of ring compensation. Data required corrosion resistance 0

    3. auxiliary seal (0-ring, V-ring, wedge-shaped ring and other special-shaped sealing ring) plays a primary role in the sealing effect of the static ring and moving ring, together also play a floating and buffering effect. It is required that the accessory ring of the stationary ring ensure the sealing between the stationary ring and the gland, so that the stationary ring has a certain degree of buoyancy; the auxiliary ring sealing element ensures the seal between the collar and the shaft or sleeve. The data required heat and cold resistance to media.

    4. Transmission members (drive pins, transmission rings, transmission seats, transmission sleeves, transmission keys, transmission lugs, or indented couplings) whose effect is to transmit the torque of the shaft to the moving ring. The data requires corrosion and wear resistance.

     5. fastening parts (set screws, spring seats, glands, assembly sleeves, sleeves) play a static, dynamic ring positioning, fastening effect. The correct positioning is required to ensure that the secondary sealing surfaces of the conflict are in the correct orientation, and that the outstanding spring pressure is maintained; together with the convenience of assembly and disassembly, it is easy to place and can be reused. The cooperation with the auxiliary seal should pay attention to installing the chamfer and the amount of compression of the seal ring, paying particular attention to the joint between the seal ring and the shaft sleeve, and require corrosion resistance and wear resistance. If necessary, use a hard surface coating.
