Description
Technical field
The utility model relates to a kind of mechanically-sealing apparatus, especially it is a kind of can two-way installation 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."
Existing mechanical seal all can only be installed unidirectionally, cannot be installed into pump at all after adjustment direction, needless to say its
To sealing function.
Utility model content
In view of this, the present invention provides a kind of two-way installation mechanically-sealing apparatus, both ends can match with pump case
Installation is closed, to adapt to the sealing demand of different medium.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of two-way installation mechanically-sealing apparatus, packet
Include the axle sleeve that fixation is placed on pump shaft and rotating ring and stationary ring that mutual cooperation is sealed；The stationary ring rear end, which is provided with, to be used for
The counterbalance spring of preload；The rotating ring is fixedly connected with axle sleeve, and the stationary ring rear end is provided with cyclic water jacket；The stationary ring, axis
Set, cyclic water jacket surround flushing chamber；Outside framework oil seal is installed between the cyclic water jacket and axle sleeve；It is characterized by: described follow
Be provided on ring water jacket outer ring surface annular boss, the annular convex platform two sides respectively with follow bad water jacket formed for be assemblied in pump
Interior installation step；Described two installation steps are equal with the spacing at axle sleeve both ends difference；And boss two sides and cyclic water jacket
Intersection is provided with sealing ring.The principles of the present invention be boss two sides all be arranged for installation positioning step, and
And it allows all equal at a distance from two end faces in boss two sides and axle sleeve.Plateau sidewall is called at a distance from end face of shaft bush axially sinks to depth
Degree.In order to adapt to the demand pumped, axial sinkage passes through calculating for each mechanical seal.By the axial sinkage on both sides
It is arranged to equally, so that the mechanical seal has the basis of two-way installation.In addition, the two sides that boss has a common boundary with cyclic water jacket are all provided with
It is equipped with sealing ring.Avoid gap leakage of the medium between pump case and boss after installing.
As an improvement the cyclic water jacket is located at the equivalent width of boss two sides.Cyclic water jacket and boss engaging portion
The width at place is called radial positioning rim of the mouth.Certainly, in order to which both ends can be installed into the pump housing, the width at other positions of cyclic water jacket is not
The width in radial positioning rim of the mouth should be greater than.
As an improvement being provided with the sensible inlet and outlet for rinsing chamber on the boss outer ring surface.No matter from which
A direction installation, inlet and outlet are all located at except pump case, and are attached with water circulating apparatus is rinsed.
The utility model has the beneficial effect that the mechanically-sealing apparatus with above structure, and both ends can install
Into the pump housing and realize sealing.For the medium of different operating conditions, it can choose the sealing means being more suitable, effectively increase machinery
The usage scenario and service life of sealing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Marked in the figure: 1 pump shaft, 2 axle sleeves, 3 rotating rings, 4 stationary rings, 5 counterbalance springs, 6 cyclic water jackets, 7 outside framework oil seals, 8 boss,
9 sealing rings, 10 water outlets；H1, H2 are axial sinkage；L1 is radial positioning rim of the mouth.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to specific implementation
The utility model is described in further detail for mode.
As shown in Figure 1, the utility model includes that the fixed axle sleeve 2 being placed on pump shaft 1 and mutual cooperation are sealed
Rotating ring 3 and stationary ring 4；4 rear end of stationary ring is provided with the counterbalance spring 5 for preload；The rotating ring 3 is fixedly connected with axle sleeve 2,
4 rear end of stationary ring is provided with cyclic water jacket 6；The stationary ring 4, axle sleeve 2, cyclic water jacket 6 surround flushing chamber；The cyclic water jacket
Outside framework oil seal 7 is installed between 6 and axle sleeve 2；The boss 8 of annular, the convex annular are provided on 6 outer ring surface of cyclic water jacket
8 two sides of platform respectively with follow bad water jacket 6 formed for be assemblied in pump in installation step；Described two installation steps with 2 liang of axle sleeve
The spacing difference at end is equal, i.e., axial sinkage H1=axial direction sinkage H2；And 8 two sides of boss and cyclic water jacket 6 have a common boundary
Place is provided with sealing ring 9.Cyclic water jacket is located at the equivalent width of boss two sides, i.e., to guarantee the width of radial positioning rim of the mouth L1
It is consistent.The sensible inlet and outlet 10 for rinsing chamber are provided on 8 outer ring surface of boss.
When use, any one end in this mechanically-sealing apparatus both ends can be packed by pump according to actual demand
In.Rotating ring 3 and quiet 4 one end can cope with some high-pressure mediums in the pump housing, and the effect of outside framework oil seal 7 at this time is only to prevent from rinsing
Water leakage；7 one end of outside framework oil seal can cope with the medium of high corrosion in the pump housing, and rotating ring 3 and the cooperation of stationary ring 4 prevent from rinsing at this time
Water leakage.
