Pump mechanical sealing works
I. What's mechanical sealing
Mechanical sealing is an axial sealing device for liquid rotor machines. It's two-axis vertical
The relative motion seal is sealed, so it is also called the end seal. Relevant in country
This is defined in the standard for mechanical sealing: "from at least one pair vertically on the rotation axis
The effect of the end in liquid pressure and compensating institutions (or magnetic force) and the combination of auxiliary seals
(b) the combination shall be maintained as a device to prevent leakage of liquids by means of a combination of relative slides. "
Mechanical sealed structures
It consists of four main components: (as shown in the attached figure)
The first part consists of a sealed end of a moving ring and a silent ring, sometimes called friction。
Part ii is a buffer compensation agency consisting of flexible originals for the main parts
It's used to fit the sealed end。
The third part consists of an auxiliary seal, which includes a moving ring and a silent ring。
And part four is the moving body that drives the motion rings around the axis。
Iii. How can a mechanical seal be achieved
As shown in the diagram, the axis rotates the ring by moving seats and push rings, and the ring is fixed
Move. Use medium pressure and spring force to close the sealed end between the motion rings
The media leak. Compensation is provided by the spring when the friction subsurface is worn. For..
Protection of the medium from leakage between the motion ring and the axis, with a moving ring seal; and
The leakage of the medium between the ring and the pressure cap was prevented。
Iv. Machical selected material
Mechanical seals consist mainly of motion rings and silent rings, which typically produce the material used in both rings
