Description
Technical field
The utility model relates to a kind of mechanically-sealing apparatus, especially a kind of strong, particulate matter multi-state suitable for corrosivity
Mechanically-sealing apparatus.
Background technique
Mechanical seal is a kind of gland seal device of rotating machinery.For example centrifugal pump, centrifuge, reaction kettle and compressor etc. are set
It is standby.Since transmission shaft is applied in inside and outside equipment, in this way, the medium in equipment is logical there are a circumferential clearance between axis and equipment
It crosses the gap to leak out, if pressure is subatmospheric in equipment, air is to equipment internal leakage, it is therefore necessary to have a resistance
The gland seal device of stopping leak leakage.There are many type of axle envelope, since mechanical seal has many advantages, such as that leakage rate is few and the service life is long, so generation
Mechanical seal is in the most important sealing mode of these equipment in boundary.Mechanical seal is called end face seal, in the related mark of country
It is defined such that in standard " by least a pair of end face perpendicular to rotation axis in Fluid pressure and compensation mechanism elastic force (or magnetic
Power) effect and auxiliary seal cooperation under keep be bonded and constituted with respect to sliding prevent fluid leak device."
It is all generally that corrosivity is strong, the medium more than particulate matter that salt chemical engineering, which pumps corresponding, common mechanically-sealing apparatus sealing
Face is not protected, direct impregnation in the medium so that its dynamic and static ring serious wear, service life are short.
Utility model content
In view of this, the present invention provides with a kind of salt chemical engineering mechanical sealing device used for pump, can be avoided rotating ring and
Stationary ring, which is exposed in medium, is corroded and generates abrasion.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of salt chemical engineering mechanical sealing device used for pump,
Including the fixed axle sleeve being placed on pump shaft, for cooperating the rotating ring and stationary ring of sealing；The rotating ring is fixed on axis by rotating seat
It puts on, the stationary ring is fixed on pump case by cyclic water jacket；The stationary ring rear end is provided with counterbalance spring；It is characterized by:
The rotating ring is arranged on rotating seat end face, and the end face of end face and stationary ring cooperates sealing；It is set on the outer ring surface of the rotating seat
It is equipped with secondary rotating ring, secondary stationary ring is provided on the cyclic water jacket, the outer ring surface of the pair rotating ring and the inner ring surface of secondary stationary ring cooperate
Sealing；The cyclic water jacket, axle sleeve, stationary ring, rotating ring, secondary rotating ring, secondary stationary ring surround flushing chamber；It is provided on the cyclic water jacket logical
Up to the inlet and outlet for rinsing chamber.
As an improvement being provided with outside framework oil seal between the cyclic water jacket and axle sleeve.
As an improvement the pair rotating ring and secondary stationary ring are graphite production.Graphite material have excellent heating conduction and
Self-lubricating property will not have an impact the rotation of rotating seat.
As an improvement the pair stationary ring is connect by stationary seat with cyclic water jacket；The pair stationary seat and secondary rotating ring
Between have gap.The particulate matter etc. that can also take away when flushing water is flowed outwardly from gap avoids secondary rotating ring and secondary stationary ring
Also it is worn.
The utility model has the beneficial effect that the mechanically-sealing apparatus with above structure, on the anchor ring of rotating seat
It is provided with secondary rotating ring and secondary stationary ring, it is ensured that really run in flushing water always for the rotating ring and stationary ring sealing surface of sealing, no
It will receive the influence of corrosive media.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Marked in the figure: 1 axle sleeve, 2 pump shafts, 3 rotating seats, 4 secondary stationary seats, 5 cyclic water jackets, 6 stationary rings, 7 counterbalance springs, 8 bones
