It includes the main casing body (1), the main casing body (1) in be equipped with oil storage chamber (2), oil storage chamber (2) be connected with prevent frostbite machine oil filling opening (3), frostproofing machine oil filling opening (3) locate to install oiling mouth sealed screw (4), oil storage chamber (2) the cavity of giving first place to and supplying in casing (1) seal spring to reciprocate, oil storage chamber (2) in filled frostproofing machine oil.
Description
Technical field
The utility model is related to a kind of accessory structure for mechanical seal, specifically refer to a kind of on refrigeration plant
The frost protection structure of mechanical seal.
Background technology
Mechanical seal is a kind of gland seal device of rotating machinery.Such as centrifugal pump, centrifuge, reactor and compressor etc. set
Standby.Because power transmission shaft is applied in inside and outside equipment, so, there is a circumferential clearance between axle and equipment, the medium in equipment leads to
Cross this gap to leak out, if pressure superatmospheric in equipment, in equipment, gas leaks out it is therefore necessary to there be one
Stop the gland seal device of leakage.The species of axle envelope is a lot, because mechanical seal has the advantages that leakage rate is lacked and life-span length, so
In the world today, mechanical seal is in these equipment topmost sealing mode.End face seal is named in mechanical seal again, in country
Be defined such that about in standard " by least one pair of perpendicular to rotation axis end face in Fluid pressure and compensation mechanism bullet
The lower fluid that prevents keeping laminating and constituting with respect to slip of the cooperation of the effect of power (or magnetic force) and auxiliary seal leaks
Device." when mechanical seal uses on refrigeration plant in prior art, produce condensed water because of the intervention of air, and then
Frost is blocking, so that spring or magnetic force lose the space of telescopic adjustment, directly in the spring of embedded mechanical seal or magnetic force mechanism
Lead between relative sliding surface at the volley it cannot be guaranteed that being tightly engaged into, and produce the leakage of fluid (cold-producing medium)！On the other hand
The oxidation of condensed water and metal surface directly affects the service life of mechanical seal！
For above-mentioned technical problem, in prior art using solution be using parcel insulation material by the way of come
Reduce the generation of condensed water, the oxidation of metal surface can be prevented simultaneously.But in practical operation, wrap up complex operation, appearance is not
Attractive in appearance it is impossible to prevent the generation of condensed water completely.
In sum, it is badly in need of at present a kind of structure will more simplifying the condensation that simultaneously can effectively eliminate in mechanical seal
Water, prevents internal structure oxidation and rusting, can greatly prolong the frost protection structure of the mechanical seal of the service life of mechanical seal.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of structure and more simplifies the machine that simultaneously can effectively eliminate
Condensed water in tool sealing, prevents internal structure oxidation and rusting, can greatly prolong the mechanical seal of the service life of mechanical seal
Frost protection structure.
For solving above-mentioned technical problem, the technical scheme that the utility model provides is: a kind of frost prevention of mechanical seal is freezed
Structure, it includes main casing, is provided with shoe cream room in described main casing body；Described shoe cream room is connected with non-congealable oil inlet, institute
At the non-congealable oil inlet stated, pouring orifice sealed screw is installed；Described shoe cream room is upper and lower for Packing spring in main casing
The cavity of movement；Non-congealable oil has been filled in described shoe cream room.
After said structure, the utility model has the advantages that the creative handle machinery of the utility model is close
The cavity moving up and down for Packing spring in the main casing body of envelope is improved to shoe cream room, and increased non-congealable oil inlet and oiling
Mouth sealed screw, has then filled non-congealable oil in shoe cream room.Without air in cavity so in mechanical seal, thus
Effectively eliminate the phenomenon that can produce condensed water when mechanical seal is used on refrigeration plant, so that mechanical seal is located always simultaneously
In machine oil, place the oxidation and rusting of mechanical seal, extend its service life！Present patent application is started with from inside, and transformation is
Some cavitys, start with from outside compared in prior art, in the baroque insulation material of housing outer wrapping of mechanical seal
More simplify and effectively.
In sum, the utility model provides a kind of structure and more simplifies and can effectively eliminate in mechanical seal simultaneously
Condensed water, prevent internal structure oxidation and rusting, the frost protection of the mechanical seal of the service life of mechanical seal can be greatly prolonged
Structure.
Brief description
Fig. 1 is the frost protection structure of mechanical seal in the utility model and the structural representation of machine envelope main body.
Fig. 2 is schematic diagram under not cutting state open for the Fig. 1.
As shown in the figure: 1, main casing, 2, shoe cream room, 3, non-congealable oil inlet, 4, pouring orifice sealed screw.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail.
In conjunction with accompanying drawing 1 and accompanying drawing 2, a kind of frost protection structure of mechanical seal, it includes main casing 1, described main casing 1
Inside it is provided with shoe cream room 2；Described shoe cream room 2 is connected with non-congealable oil inlet 3, installs at described non-congealable oil inlet 3
There is pouring orifice sealed screw 4；Described shoe cream room 2 is the cavity moving up and down for Packing spring in main casing 1；Described oil storage
Non-congealable oil has been filled in chamber 2.
After said structure, the utility model has the advantages that the creative handle machinery of the utility model is close
The cavity moving up and down for Packing spring in the main casing 1 of envelope is improved to shoe cream room, and increased non-congealable oil inlet 3 and note
Hydraulic fluid port sealed screw 4, has then filled non-congealable oil in shoe cream room 2.Without air in cavity so in mechanical seal,
Thus having effectively eliminated the phenomenon that can produce condensed water when mechanical seal is used on refrigeration plant, make mechanical seal one simultaneously
Directly it is in machine oil, place the oxidation and rusting of mechanical seal, extend its service life！Present patent application is started with from inside, changes
Make existing cavity, start with from outside compared in prior art, in the baroque insulation of housing outer wrapping of mechanical seal
Material is more simplified and effectively.
In sum, the utility model provides a kind of structure and more simplifies and can effectively eliminate in mechanical seal simultaneously
Condensed water, prevent internal structure oxidation and rusting, the frost protection of the mechanical seal of the service life of mechanical seal can be greatly prolonged
Structure.
Above the utility model and embodiments thereof are described, this description does not have restricted, shown in accompanying drawing
Also it is one of embodiment of the present utility model, actual structure is not limited thereto.If generally speaking this area is general
Logical technical staff is enlightened by it, in the case of creating objective without departing from the utility model, designing and being somebody's turn to do without creative
The similar frame mode of technical scheme and embodiment, all should belong to protection domain of the present utility model.
