Description
Technical field
The present invention relates to a kind of sealing member, a kind of anti-dry friction mechanical seals.
Background technology
Mechanical seal (mechanical seal) refers to be perpendicular to the end face of rotation axis at fluid pressure by least one pair of
Effect with compensation mechanism elastic force (or magnetic force) lower and auxiliary seal coordinate lower holding laminating relative slip are constituted
Prevent the device that fluid leaks.Elastic force load maintainer and auxiliary seal be metallicity stricture of vagina pipe mechanical seal we be referred to as metal wave
The stricture of vagina seal of tube.
In use, if there is the phenomenon of dry grinding, mechanical seal is easily damaged traditional mechanical sealing member.
Summary of the invention
It is an object of the present invention to provide one to prevent from being worn, the anti-dry friction mechanical improving anti-wear performance seals.
The present invention solve technical problem provide following scheme:
A kind of anti-dry friction mechanical seals, including rotating ring and stationary ring, it is characterised in that: described rotating ring is fixedly mounted on pump shaft, institute
The side stating pump shaft is provided with stationary seat, and the end face of described stationary seat is provided with external sheath layer, is slidably fitted with in described external sheath layer
Stationary ring, the bottom of described stationary ring connects spring base, and the bottom of described spring base connects spring, and the surface of described stationary seat is provided with bullet
Spring hole, the bottom of described stationary ring is provided with dowel hole, and described stationary ring, the sidewall of rotating ring are provided with the seal face worked in coordination,
Described rotating ring, stationary ring use dry grinding type pressureless sintering carborundum.
It is cased with rubber parts on the outer wall of described rotating ring.
The present invention is fixedly mounted on pump shaft at rotating ring, is provided with stationary seat in the side of rotating ring, and the end face at stationary seat sets
There is external sheath layer, in external sheath layer, be slidably fitted with spring base, be provided with spring, such rotating ring and stationary ring in the bottom of spring base
Between work in coordination, the adjacent face of rotating ring and stationary ring is provided with seal face, which reduces contact area, if it occur that
Dry grinding, is also unlikely to grind away dynamic and static ring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Seeing accompanying drawing, a kind of anti-dry friction mechanical seals, and including rotating ring 1 and stationary ring 2, described rotating ring 1 is fixedly mounted on pump shaft
On 10, the side of described pump shaft 2 is provided with stationary seat 3, and the end face of described stationary seat 3 is provided with external sheath layer 4, described external sheath layer 4
Inside being slidably fitted with stationary ring 2, the bottom of described stationary ring 2 connects spring base 5, and the bottom of described spring base 5 connects spring 6, described
The surface of stationary seat 3 is provided with spring eye 7, and the bottom of described stationary ring 2 is provided with dowel hole 8, described stationary ring 2, rotating ring 1 sidewall on
Being provided with the seal face worked in coordination, described rotating ring, stationary ring 1,2 use dry grinding type pressureless sintering carborundum to make.
It is cased with rubber parts 9 on the outer wall of described rotating ring 1.
