Description
Technical field
The present invention relates to filter technology field, more specifically to a kind of filter with excellent seal
And its shaft seal assembly.
Background technology
Filter is widely used in industrial production and manufacturing field, and filter brush axis and the sealing of cylinder and filtering cartridge lid are main
It is completed by filter seal component.Filter long-play will cause axle envelope to be worn, as filter goes out due to axle envelope is worn
Existing internal sewage leakage phenomenon, will seriously affect the normal operation of equipment, therefore the sealing effect of filter is to its long-time
Stable operation is very crucial.
Referring to Fig. 1, Fig. 2 and Fig. 3, sealing flange 12 passes through fastening bolt for widely used shaft seal assembly on the market at present
13 are fixed on filtering cartridge lid 14, are coordinated between sealing flange 12 and brush axis 11 using H5/d5.First O-ring seal 16, the 2nd O
Type sealing ring 17 generates initial pressure when installing, and the first O-ring seal 16, the second O-ring seal 17 are with Fluid pressure during work
Maximum sealing force is generated, using the elasticity and plasticity close fit gap of material body, so as to reach sealing effect.YXd is sealed
Circle 15 be it is a kind of have at two seals lip and outer diameter be tight fit lip packing.Due to there is additional profit between twice lip
Lubrication prescription, therefore friction and wear is prevented significantly, wearability is good, and impact resistance is resisted out, and compressive deformation is small, improves sealing performance.
Using twice O-ring seal, the sealing structure of YXd sealing rings together between sealing flange 12 and brush axis 11, make sealing flange 12
It is formed with the gap among brush axis 11 and closed reaches sealing effect；Sealing flange 12 is sealed with filtering cartridge lid 14 using O-ring seal,
Effective closed contact surface of the sealing flange 12 with filtering cartridge lid 14.
The filter core locating flange of conventional filter with upper element using mold positioning method welding production, brush axis also need through
Crossing the processes such as vehicle, milling, welding, correction can just complete.Brush axis 11 is assembled with both ends sealing flange 12 and nylon sleeve cooperation,
Concentric fit face is formed with strainer during rotation, it is higher to all component concentricity requirements.Due to sealing flange 12 and nylon sleeve
Fit dimension is positioned by mold and obtained, and each component spot welding, which positions, after mold positioning further takes out mold, and all assemblies are welded
It connects, and workpiece welding is also easy to produce welding deformation, fit dimension can generate variation and cause brush axis 11, sealing flange 12 and nylon sleeve
Concentricity it is inconsistent.And brush axis 11, using stainless steel material, diameter is small, length is longer, when processing, is also easy to produce bounce, cooperation ruler
It is very little to be also easy to produce variation；It is welded after machining, brush axis 11 generates welding deformation, and correction is also difficult to restore completely, causes workpiece concentric
Degree is difficult to ensure that.Although sealing ring wear-resisting property is preferable, on condition that circular motion must be kept by seal member, if close
It seals component decentraction and forms elliptic motion, due to the two material hardness difference, sealing ring can quickly be destroyed and lose close
Seal function.Therefore, there are still many problems for existing filter axle envelope, still need to further perfect.
Through retrieval, China Patent No. ZL201420006764.7, authorized announcement date is August in 2014 13 days, innovation and creation
It is entitled：Pulp water circulating water strainer rotating shaft sealing structure；This application includes blowdown and inhales dip tube axis, tank body, sealing shroud and pressure
Lid；Annular seal space is provided in tank body, sealing shroud is mounted on annular seal space top, tank body open top, and is open and annular seal space phase
Logical, gland is mounted on opening, and blowdown inhales dip tube axis and sequentially passes through gland, sealing shroud and tank body, and sealing shroud bottom end is provided with down
Placed cavity, and lower placement intracavitary is provided with lower seal, the central part of lower seal is adjacent to blowdown and inhales dip tube axis；Sealing shroud
Top is provided with placed cavity, and sealing ring and carbon packing ring are provided in upper placed cavity, and carbon packing ring is located at upper
The lower section of sealing ring, is adjacent to the bottom of gland at the top of upper sealing ring, and the central part of upper sealing ring and carbon packing ring pastes
Dip tube axis is inhaled in close-up dirt.The pulp water circulating water strainer rotating shaft sealing structure of this application improves blowdown and inhales dip tube sealing effect
Fruit.But it is longer that this application can not solve brush shaft length, and when processing is also easy to produce bounce, is easily produced with other assembly fit dimensions
Changing, the problem of causing the concentricity of brush axis, sealing flange and nylon sleeve inconsistent.
