Description
Technical field
The utility model relates to mechanically-sealing apparatus production fields more particularly to a kind of labyrinth mechanical seal of band plain type to fill
It sets.
Background technique
Mechanical seal refer to by least a pair of end face perpendicular to rotation axis Fluid pressure and compensation mechanism elastic force (or
Magnetic force) under the action of and the cooperation of auxiliary seal under keep be bonded and constituted with respect to sliding prevent fluid leak dress
It sets.
Mechanical seal is a kind of gland seal device of rotating machinery.Since transmission shaft is applied in inside and outside equipment, in this way, axis with set
There is a circumferential clearance between standby, the medium in equipment is leaked out by the gap, if pressure is lower than atmosphere in equipment
Pressure, then air is to equipment internal leakage, it is therefore necessary to have the gland seal device for preventing leakage.There are many type of axle envelope, due to machine
Tool sealing has many advantages, such as that leakage rate is few and the service life is long, so mechanical seal is in the most important sealing of these equipment in the world
Mode.Easily there is wearer and falls into material in conventional mechanical sealing, and client's inventory disposal or particulate species material is caused to enter friction
Pair causes mechanical seal to fail.
Utility model content
Utility model provides a kind of band plain type labyrinth mechanically-sealing apparatus, effectively reduces pellet material and is sealed
A possibility that face, sealing performance are more reliable.
In order to reach the purpose, utility model is adopted the following technical scheme that
A kind of band plain type labyrinth mechanically-sealing apparatus, including connecting flange, upper stationary seat, bearing block and bearing pressure
It covers, self-aligning roller bearing is flanked in the bearing block, the self-aligning roller bearing inner sleeve is equipped with axle sleeve, connects under the axle sleeve
Balance set, it is characterised in that: the connecting flange inner ring, the balance set, the axle sleeve outer ring and the upper stationary seat are constituted
Seal chamber, seal assembly is equipped in the seal cavity, and the balance set end is equipped with labyrinth part, the labyrinth part and the company
Acting flange cooperation constitutes labyrinth seal.
As a preference, the seal assembly includes the first rotating ring, the first stationary ring, the second rotating ring and the second stationary ring, institute
State connecting flange and the upper stationary seat fix first stationary ring and second stationary ring respectively, first rotating ring with it is described
Spring base, the spring base and first rotating ring and second rotating ring is equipped between second rotating ring to pass by shifting fork structure
It is dynamic.
As a preference, first rotating ring and second rotating ring are graphite insert structure.
As a preference, the spring base, the balance set are fastened with the axle sleeve with screw.
As a preference, the balance set left end and labyrinth part are fastened with screw and are held tightly.
As a preference, the labyrinth part, the connecting flange inner ring, the seal assembly and the balance set shape
At sealing cavity.
To sum up, compared with prior art, be the advantages of utility model: labyrinth part and connecting flange cooperate, and effectively reduce
A possibility that pellet material is sealed face, sealing performance is more reliable.
