Description
Technical field
The utility model belongs to Oil-gas Separation technical field, more particularly to a kind of gs-oil separator sealing structure.
Background technology
Currently, sealing structure will be equipped between drive chamber and separation chamber in centrifugal oil-air separator.
Above-mentioned known sealing structure such as prior art Publication No. CN101189414A, it is entitled for crank box
" the device for purification gas while being evacuated to crank box disclosed in the device of purification gas while pumping
(10), described device (10) includes：Shell (12) is internally provided with separation chamber (14) ,-turn with armature spindle (32) and centrifugation
The rotor structure of sub (39), armature spindle (32) are rotatably installed in the shell, and centrifugal rotor (39) is located at separation chamber
(14) in, and-fluid drive apparatus (64), it is used for by driving fluid driven rotor axis (32), the driving device
(64) it is arranged in the drive chamber (60) separated with separation chamber (14) by case partition (16), the armature spindle (32) extends
Passing through the through hole in case partition (16), which is characterized in that labyrinth packing (70) is arranged in the region of through hole, with
Drive chamber (60) and separation chamber (14) are sealed, case partition (16) includes axle sleeve (36), and bearing (36) is especially ball bearing quilt
It is contained in axle sleeve to support armature spindle (32), axle sleeve (36) to be integrally formed in case partition (16), the axle sleeve has
Pipe sleeve (36), the pipe sleeve project to drive chamber (60).The labyrinth seal has seal washer (70), the seal washer
(70) circular axial notch (76) is carried, the free end of the pipe sleeve (36) preferably contactlessly connects with axial notch (76)
It closes.”；Due to using labyrinth packing, needing seal washer, and seal washer must be fixedly arranged at armature spindle or driving wheel
On, and seal washer is relatively thin, the case where being susceptible to deformation；And the end face of the free end of pipe sleeve and inside and outside wall and axial notch
It must assure that certain interval, gap is too big then to cannot achieve sealing, and the too small then machining accuracy in gap is higher and installation accuracy is equal
It is higher, therefore exist and cumbersome, the problem that machining accuracy is higher and stability in use is poor is installed.
Utility model content
Technical problem to be solved by the utility model is to provide a kind of simple installation, machining accuracy is relatively low and makes
With the preferable gs-oil separator sealing structure of stability.
In order to solve the above technical problems, a kind of gs-oil separator sealing structure provided by the utility model, it includes chamber
Body partition board, shaft and drive disk, the cavity partition board are equipped with casing, and the shaft lower end connects after passing through casing with drive disk
It connects, the outer diameter of the drive disk is more than the outer diameter of casing, and the spacing between described sleeve pipe lower face and drive disk upper surface is 0.1
The upper surface of~2mm, the drive disk are equipped with multiple blades, and multiple blades are evenly distributed.
After using the above structure, the utility model compared with prior art, due to lower end face and drive disk upper surface
Between spacing be 0.1~2mm, then oil is not easily accessible in this spacing range, can play certain sealing function, and only end face
Between have pitch requirements, it is only necessary in shaft control position can be realized so that the machining accuracy of each component is relatively low；And
The upper surface of drive disk is equipped with multiple blades, under the action of moving blade, can arrange oil outward, so that in driving chamber
Oil be not easily accessible in disengagement chamber, eliminate original gasket while keeping equal sealing effect.Therefore this practicality
It is novel to have the characteristics that simple installation, machining accuracy are relatively low and stability in use is preferable.
As an improvement, the multiple blade is divided into two groups, one group of multiple blade in two groups are surrounded in drive disk upper surface
Cricoid internal diameter be more than the outer diameter of casing, the cricoid outer diameter that the multiple blades of another set are surrounded in drive disk upper surface is less than
The internal diameter of casing, and the upper end of the multiple blades of another set is located in lower end；Then in this way after setting, it is negative that blade forms twice
Trim ring so that the fluid in disengagement chamber is easier to be discharged in driving chamber, and the fluid in driving chamber is not easily accessible in disengagement chamber,
Ensure that the fluid in driving chamber is not easy to generate secondary pollution to the oil gas in disengagement chamber.
As an improvement, the cricoid internal diameter that the multiple blade is surrounded in drive disk upper surface is more than the outer diameter or more of casing
The cricoid outer diameter that a blade is surrounded in drive disk upper surface is less than the internal diameter of casing；When then in casing, it is easier to be formed negative
Pressure, so that the fluid in disengagement chamber is easier to be discharged in driving chamber, and the fluid in driving chamber is not easily accessible disengagement chamber
In, ensure that the fluid in driving chamber is not easy to generate secondary pollution to the oil gas in disengagement chamber.
As an improvement, the drive disk upper surface is equipped with annular protrusion, the internal diameter of the annular protrusion is more than casing
Outer diameter or the internal diameter of described sleeve pipe are more than the outer diameter of annular protrusion；Then after annular protrusion setting, rushing for initial resistance oil can be played
It hits, can further improve the effect of clearance seal.
Preferably, the spacing between the annular protrusion inner wall and sleeve outer wall is 0.1~2.5mm.
Preferably, the spacing between described sleeve pipe inner wall and annular protrusion outer wall is 0.1~2.5mm.
As an improvement, the lower section of the drive disk is equipped with bearing, the shaft lower end connect with bearing, is set in described sleeve pipe
There are fan or the demarcation strip of annular；The fan is connect with shaft, and shaft drives fan rotation；The demarcation strip and shaft or with
Casing connection；Then after fan setting, negative pressure can be formed in casing, so that the fluid in disengagement chamber is easier to be discharged to driving
It in chamber, and is less susceptible to enter in disengagement chamber with the fluid in driving chamber after blade comprehensive function, ensures the fluid in driving chamber
It is not easy to generate secondary pollution to the oil gas in disengagement chamber；And reduce the cross-sectional area in channel in casing after demarcation strip setting, in this way
After isolation under the action of fluid, so that the oil gas in disengagement chamber is not easily accessible in driving chamber, ensure two way seal effect
Fruit.
As an improvement, between the fan and drive disk, there are gaps；Then in this way after setting, it is easier to negative pressure is generated, it is close
It is also just more preferable to seal effect.
As an improvement, the drive disk upper surface is equipped with protrusion, the lower face of the fan is supported with raised upper surface and is closed；
Then in this way after setting, other mechanisms need not be set so that there are gaps between fan and drive disk, it is simple in structure, it is easy into
Type, processing cost is relatively low, also allows for installing.
As an improvement, the demarcation strip is truncated cone-shaped structure；When the demarcation strip is connect with shaft, demarcation strip periphery wall with
Gap between casing internal perisporium is 0.1~2.5mm, and the outer diameter of demarcation strip upper end is less than the outer diameter of demarcation strip lower end；It is described
When demarcation strip and casing connection, demarcation strip is an integral structure with casing, between demarcation strip internal perisporium and shaft periphery wall between
Gap is 0.1~2.5mm, and the outer diameter of demarcation strip lower end is less than the outer diameter of demarcation strip upper end；Then in this way after setting so that disengagement chamber
Fluid after middle separation is easier to gather at gap, can further improve sealing effect.
