Description

A kind of mechanical shaft seal
Technical field
This utility model relates to sealing device technical field, is specially a kind of mechanical shaft seal.
Background technology
Mechanical oil seal refer to by least one pair of be perpendicular to the end face of rotation axis fluid pressure and compensation mechanism elastic force (or Magnetic force) effect is lower and coordinating of auxiliary seal lower keep laminating and relatively slide and the dress preventing fluid from leaking that constitutes Put.Elastic force load maintainer and auxiliary seal be metallicity stricture of vagina pipe mechanical seal we be referred to as the wavy metal seal of tube.Light-duty In sealing, also having and use rubber bellows to make auxiliary seal, rubber bellows elastic force is limited, expires it is generally required to be aided with spring Foot loads elastic force.Mechanical seal is generally referred to as machine envelope by people.Along with the development of machinery industry, mechanical oil seal is at machinery Being requisite in industry, it is prevented from the leakage of fluid.But for current mechanical oil seal, generally there is mill Damaging big, service life is short, the weak effect of sealing, easily produces the leakage of fluid, and to environment, cooling effect difference etc. is asked Topic.
Utility model content
The purpose of this utility model is to provide a kind of mechanical shaft seal, to solve the abrasion proposed in above-mentioned background technology Greatly, service life is short, the weak effect of sealing, easily produces the leakage of fluid, and to environment, cooling effect difference etc. is asked Topic.
For achieving the above object, this utility model following technical scheme of offer: a kind of mechanical shaft seal, enter including cooling water Mouth, transmission screw, stationary ring pad and bearing (ball) cover, the lower end of described cooling water inlet is provided with axle sleeve, described cooling water inlet Right positions stationary ring is installed, the right of described stationary ring is fixed with rotating ring, and the left side of described transmission screw connects locking screw Following closely, and the left side of lock-screw is provided with rotating ring, the lower section of described transmission screw is provided with bearing, and the upper end of described bearing is fixed Having bearing (ball) cover, the right side of described bearing (ball) cover connects has lubricating oil, the left of described bearing (ball) cover to be fixed with outside framework oil seal, and The left side of outside framework oil seal is provided with spring, and the right of described stationary ring pad is provided with seal ring of moving ring, described seal ring of moving ring Right side connects has O, the right of described O to be provided with rotating ring support.
Preferably, described cooling water inlet is provided with 2, and with axle sleeve as symmetrical structure.
Preferably, described stationary ring and sealing between section of rotating ring are the least gap, and have one layer of liquid film in gap.
Preferably, described rotating ring is connected by spring outside framework oil seal.
Compared with prior art, the beneficial effects of the utility model are: this mechanical oil seal, use outside framework oil seal and elastic benefit Repaying sealing between section of mechanism, stationary ring and rotating ring is the least gap, and has one layer of liquid film in gap, plays lubrication, The abrasion produced is little, and the life-span of use is long, and sealing effective will not produce the leakage of fluid, seal equipped with sealing ring, Carry out reliable sealing, environment will bring pollution, cooling water inlet are provided with 2, and with axle sleeve as symmetrical structure, cold But speed is fast, effective.
Accompanying drawing explanation
Fig. 1 is this utility model structure overall schematic.
In figure: 1, axle sleeve, 2, cooling water inlet, 3, stationary ring, 4, rotating ring, 5, lock-screw, 6, transmission screw, 7, bearing, 8, stationary ring pad, 9, seal ring of moving ring, 10, O, 11, rotating ring support, 12, spring, 13, outside framework oil seal, 14, bearing (ball) cover, 15, lubricating oil.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Fig. 1, a kind of technical scheme of this utility model offer: a kind of mechanical shaft seal are provided, including cooling water inlet 2, pass Dynamic screw 6, stationary ring pad 8 and bearing (ball) cover 14, the lower end of cooling water inlet 2 is provided with axle sleeve 1, and cooling water inlet 2 is provided with 2 Individual, and with axle sleeve 1 as symmetrical structure, the right positions of cooling water inlet 2 is provided with stationary ring 3, the sealing of stationary ring 3 and rotating ring 4 is broken Being the least gap between face, and have one layer of liquid film in gap, the right of stationary ring 3 is fixed with rotating ring 4, the left side of transmission screw 6 Connecting and have lock-screw 5, and the left side of lock-screw 5 is provided with rotating ring 4, rotating ring 4 is connected by spring 12 outside framework oil seal 13, The lower section of transmission screw 6 is provided with bearing 7, and the upper end of bearing 7 is fixed with bearing (ball) cover 14, and the right side of bearing (ball) cover 14 connects to be had Lubricating oil 15, the left of bearing (ball) cover 14 is fixed with outside framework oil seal 13, and the left side of outside framework oil seal 13 is provided with spring 12, stationary ring The right of pad 8 is provided with seal ring of moving ring 9, and the right side of seal ring of moving ring 9 connects O 10, and the right of O 10 is arranged Rotating ring is had to support 11.
Operation principle: when using this mechanical oil seal, pressure and the effect of spring force produced by medium so that close There is certain thrust on envelope section, the spring 12 that now rotating ring supports on 11 carries out stretch compensation effect, and at rotating ring 4 And sealing of stationary ring 3 forms the least gap between section, have one layer of liquid film in keeping gap, and gap is the least, so medium leads to The resistance crossed is very big, thus prevents the leakage of liquid, and the existence Castor Oil friction pair of liquid film, alleviate abrasion, it is ensured that Sealing effectiveness, rotating ring 4 is sealed by sealing ring with axle sleeve 1 respectively with bearing 7, stationary ring 3, then coordinates upper lock-screw 5, passes Dynamic screw 7 and outside framework oil seal 13, blocked the whole possible approach that liquid in annular seal space leaks out, it is achieved that the closeest Envelope, here it is the operation principle of this mechanical oil seal.
Embodiment the most of the present utility model, for the ordinary skill in the art, It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
