Description
Technical field
The utility model is related to filter technology fields, more specifically to a kind of mistake with excellent seal
Filter 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 because 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 using H5/d5 between sealing flange 12 and brush axis 11.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 when work
Maximum sealing force is generated, using the elasticity and plasticity close fit gap of material body, to reach sealing effect.YXd is sealed
Circle 15 is a kind of lip packing having at two seals lip and outer diameter for tight fit.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,
The effective closed contact surface of sealing flange 12 and filtering cartridge lid 14.
The filter core locating flange of conventional filter and upper element use 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 when rotation, it is higher to all component concentricity requirements.Due to sealing flange 12 and nylon sleeve
Fit dimension is positioned by mold and is obtained, and each component spot welding, which positions, after mold positioning further takes out mold, is welded to all assemblies
It connects, and workpiece welding is also easy to produce welding deformation, fit dimension will produce variation and cause brush axis 11, sealing flange 12 and nylon sleeve
Concentricity it is inconsistent.And brush axis 11 uses stainless steel material, diameter is small, length is longer, and 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.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, since the two material hardness is different, sealing ring can quickly be destroyed and lose close
Seal function.Therefore, existing filter axle envelope still needs to further perfect there are still many problems.
Through retrieval, China Patent No. ZL201420006764.7, authorized announcement date is August in 2014 13, innovation and creation
It is entitled：Pulp water circulating water strainer rotating shaft sealing structure；This application includes that dip tube axis, tank body, sealing shroud and pressure are inhaled in blowdown
Lid；Seal chamber is provided in tank body, sealing shroud is mounted on seal chamber top, top of the tank opening, and is open and seal chamber 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 upper 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 for causing the concentricity of brush axis, sealing flange and nylon sleeve inconsistent.
