Description
Technical field
The utility model relates to mechanically-sealing apparatus production field more particularly to a kind of mechanically-sealing apparatus of erosion resistant.
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.The medium tool of some mechanical seal structure contacts has corrosivity, such as extracts the vacuum pump of corrosive gas or liquid, existing
Have that mechanical seal structure does not have corrosion resistance mostly or structure is excessively complicated, therefore in use, structure can be gradually
It is damaged by corrosion or influences sealing effect because of structural stability difference.
Utility model content
Utility model provides a kind of mechanically-sealing apparatus of erosion resistant, solves the metalwork in machine seal apparatus vulnerable to corruption
It is the problem of erosion, simple and reliable for structure, long service life.
In order to reach the purpose, utility model is adopted the following technical scheme that
A kind of mechanically-sealing apparatus of erosion resistant, including axle sleeve, rotating ring, stationary ring, connecting flange component, throw-out collar component, bullet
Spring and seal assembly, rotating ring are fixed in the left end groove of axle sleeve, and the left side of stationary ring is close to the right side of rotating ring
Connection setting, the throw-out collar component are arranged in the right side of the stationary ring and are close to setting, the company with the right side of the stationary ring
Acting flange component inner ring, the axle sleeve outer ring and the seal assembly constitute a seal chamber, and the spring is set and the throw-out collar
Between component and the connecting flange component.
As a preference, the axle sleeve left end groove outer rim and the rotating ring end are equipped with mutually matched Step-edge Junction
Structure is provided with O-ring between two step structures.
As a preference, connecting flange component left end is provided with flange protecting cover, the connecting flange component and institute
It states and is equipped with the O-ring between flange protecting cover.
As a preference, the flange protecting cover material uses silicon carbide material.
As a preference, the seal assembly includes ash stop plate and A type sealing ring, the A type sealing ring is located at described
Close to the spring one end on the inside of connecting flange component.
To sum up, compared with prior art, be the advantages of utility model: rotating ring connect with sleeve end groove, cooperates two
Step structure and O-ring between person realize sealing and anti-corrosion；Flange protecting cover uses the carbofrax material of highly corrosion resistant, with
Pump cover coats connecting flange, improves the corrosion resistance of structure.
