Description
Technical field：
The present invention relates to a kind of mechanical seal structure more particularly to a kind of packaging types to cool down anhydrous mechanical seal certainly.
Background technology：
Mechanical seal is the fitting realization sealing by two anchor rings of a pair of of dynamic and static ring.Mechanical seal is running at high speed
When, the sealing ring surface of two fittings constantly rubs and can generate very big heat, the heat that standard machinery sealing dynamic and static ring friction generates
Very big, the air flowability that dynamic and static ring is contacted is very poor, and the heat that dynamic and static ring friction generates, which easily gathers, to be not easy to distribute, and is not added with cold
But the dynamic and static ring of water cooling mechanical seal, mechanical seal will be burnt quickly or the service life is very short.Used by standard machinery seals
There are two types of modes for the mode of cooling dynamic and static ring：One kind is interior cooled, and another kind is outer cooled.Two ways will consume greatly
Industrial water is measured to cool down.Some gives the additional cooler of mechanical seal, but cooler is also required to consume a large amount of industrial water ability
Cool down cooler.These cooling waters need one independent equipment of increase that could provide, and the cooling water water source will also be protected
Demonstrate,prove necessarily required water quality and pressure.Standard machinery sealing is really water consumption power consumption, and increase a large amount of plant maintenance amount.
Invention content：
Do not have to external cooling water and using cooler the purpose of the present invention is to provide one kind, Jie in the pump housing is fully utilized
The packaging type of heat cools down anhydrous mechanical seal certainly produced by matter cooling dynamic and static ring spin friction.
The present invention is implemented by following technical solution：Packaging type is from cooling down anhydrous mechanical seal, including axle sleeve, rotating ring, quiet
Ring and flange；It is sequentially installed with the rotating ring, stationary ring and flange from inside to outside on the axle sleeve outer wall；The rotating ring and described
The adjacent anchor ring CONTACT WITH FRICTION of stationary ring；It further includes ring seal O-ring, rotating ring fixing nut, compresses seal O-ring；Institute
The rotating ring erecting bed that annular is coaxially fixed on axle sleeve outer wall is stated, the rotating ring erecting bed and the axle sleeve are into a single integrated structure；
The rotating ring split turning set is on the rotating ring erecting bed outer wall；In the rotating ring erecting bed outer wall close to the stationary ring
On be coaxially fixed with protrusion annular seal ring of moving ring installation step, the seal ring of moving ring installation step and the rotating ring
Erecting bed is into a single integrated structure；Rotating ring endoporus corresponding with the seal ring of moving ring installation step is provided in the collar extension of the rotating ring
Step；Ring seal ring recess is formed between the seal ring of moving ring installation step and the rotating ring endoporus step, in the rotating ring
Split is movably equipped with the ring seal O-ring on the rotating ring erecting bed outer wall in seal groove；In the annular rotating ring
The rotating ring fixing nut is bolted on the axle sleeve outer wall on the inside of erecting bed；Consolidate in the rotating ring adjacent with the rotating ring
Nut end face is determined equipped with ring compression seal groove, and split is equipped with the compression sealing in the ring compression seal groove
O-ring；Tapered step is processed on the outer wall of the stationary ring, taper groove, the cone are machined in the collar extension of the flange
It spends step and the taper groove forms isolating seal circle fixing groove, split set is installed with institute in the isolating seal circle fixing groove
State isolating seal O-ring.
Preferably, it is fixed with axial blade on the outer wall of the rotating ring fixing nut.
Preferably, it is provided with inner chamfer on the inner wall of the rotating ring collar extension adjacent with the stationary ring.
Preferably, it is provided with outer chamfer on the outer wall of the rotating ring collar extension adjacent with the stationary ring.
Advantages of the present invention：Simple in structure, easy to process, service life is long.Packaging type designs, and an entirety can be used as to pacify
Assembly and disassembly.Handling are quite convenient to.Heat caused by the medium cooler envelope dynamic and static ring spin friction in the pump housing is fully utilized
Amount.Increase equipment without the cooling exclusively for mechanical seal, increase cooler without in machine envelope side.Device context is cold
But the pipeline of water setting can remove, and field device seems more succinct clean.It is extensive using medium, in lime stone slurry, urine
Plain solution etc. easily crystallizes, and can be used in the medium of fouling.This product will be major industry energy conservation emission reduction and ultralow row
It puts, reduces industrial wastewater pollution, save a large amount of industrial waters and play a great role.Particularly in power plant desulfurization, denitrating system
On using effect it is especially pronounced.
