It is high.
Dust seal test plus apparatus for ash used in the dust seal test to automobile air filter assembly are more difficult at present
Control and realization test objective, are mainly reflected in following three points:
1, it is whole-process automatic plus grey to cannot achieve test；
2, it is unable to control and adds grey rate；
3, experimentation cost is higher.
It is automatic plus grey plus grey fast during carrying out vibration endurance test how a kind of automobile air filter assembly component is designed
Rate is controllable, and the dust seal experimental rig that test efficiency can be improved is project that the present inventor concentrates on studies.
Utility model content
The purpose of this utility model is to provide a kind of dust seal experimental rig, can guarantee vibrate it is resistance to
Automatic continuous during test plus ash long can control and add grey rate, greatly improves test efficiency, and structure is simple, examination
Test cost reduction.
To achieve the goals above, the technical solution of the utility model are as follows: a kind of dust seal experimental rig,
In include pallet and the spray ash structure above pallet, the pallet by power mechanism drive rotate, the pallet inner cavity is set
There is cricoid partition, dust is contained in the ring-shaped cavity between the partition and pallet outer rim, the grey structure of the spray includes threeway
Three interfaces of valve, the triple valve are separately connected sweep-up pipe, dust outlet tube and air-pressure tube, and the other end of the sweep-up pipe faces
The other end of the open end of the ring-shaped cavity, the air-pressure tube is connect with air compressor machine.
The utility model dust seal experimental rig, wherein the power mechanism uses motor, the bottom surface of the pallet
The output axis connection in centre and the motor.
The utility model dust seal experimental rig, wherein further including bracket, the bracket is supported in below pallet.
The utility model dust seal experimental rig, wherein the air compressor machine is installed on bracket.
After adopting the above scheme, the utility model dust seal experimental rig has the advantages that
1, by adjusting the pressure of air compressor machine, it can be achieved that control plus grey rate and ash load, make to inhale by the pallet of rotation
Dirt pipe encloses sucking dust along pallet one, can guarantee the primary dust that sufficient amount is added and even suction system, meets test need
It wants, reduces labour cost；
2, the utility model uses the building that several simple machines complete this device, and structure is simple, greatly reduces
Experimentation cost；
3, most of dust seal test can be carried out, and improves efficiency, and reduce costs.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model dust seal experimental rig；
Fig. 2 is the example structure schematic diagram of the utility model dust seal experimental rig.
With reference to the accompanying drawing, the utility model is described further by embodiment；
Specific embodiment
The schematic perspective view of the utility model dust seal experimental rig as shown in Figure 1, including pallet 1 and be set to
The spray ash structure of 1 top of pallet.The pallet 1 is circle, and the inner cavity of pallet 1 is equipped with circular partition 2, partition 2 and pallet 1
Outer rim be concentric.Ring-shaped cavity 3 is formed between partition 2 and the outer rim of pallet 1, is used to contain dust in the ring-shaped cavity 3.
Pallet 1 is driven by power mechanism and is rotated.The power mechanism uses motor 4, the bottom center position of pallet 1 and the output of motor 4
Axis connection is fixed.The pallet 1 is set to the upper surface of bracket 5, and bracket 5 is used to support pallet 1.
Spraying grey structure includes triple valve 6, and three interfaces of the triple valve 6 are separately connected sweep-up pipe 7, dust outlet tube 8 and pneumatics
Pipe 9, the other end of sweep-up pipe 7 face the open end of ring-shaped cavity 3, i.e. the lower part of sweep-up pipe 7 is in a vertical shape to be vertical at ring
The upper surface of shape cavity 3.The other end of air-pressure tube 9 is connect with air compressor machine 10, and air compressor machine 10 is installed on bracket 5.
As shown in connection with fig. 2, which when in use, air filter sample 12 is placed on by vibration test requirement
On shake table 14, air compressor machine 10 is pressurizeed, flow is generated in three joints of triple valve 6, is learnt, moved according to Bernoulli equation
Pressure is less than static pressure, so generating suction in sweep-up pipe 7, then dust can enter in sweep-up pipe 7, reaches the joint of triple valve 6,
Again by the thrust of air compressor machine 10, dust 11 will be sprayed from dust outlet tube 8, into enclosure space 13.It is put in enclosure space 13
Given the test agent is set, the present embodiment is air filter sample 12, and air filter sample 12 is placed on shake table 14 simultaneously, is being vibrated
While endurance test, air filter sample 12 is allowed to be among uniform dust space.Vibration test terminates, and reaches and finally tests
Purpose -- also examination checks the anti-dust performance of air filter sample while sample mechanical oscillation.During test, tune can be passed through
The pressure of air compressor machine 10 is saved to realize the control to grey speed is added；Meanwhile it being paved with dust on pallet 1, it is driven using motor 4
Pallet 1 rotates, and allows sweep-up pipe 7 that can uniformly be drawn onto the dust in entire pallet 1, when effectively extending the test for adding primary ash
Between, be not in the dust near sweep-up pipe 7 is sucked and the case where the dust at other positions is not drawn onto pallet 1, greatly
Ground reduces labour cost, improves test efficiency.
The utility model dust seal experimental rig is by adjusting the pressure of air compressor machine 10, it can be achieved that control plus grey rate
And ash load, so that sweep-up pipe 7 is enclosed sucking dust along pallet 1 one by the pallet 1 of rotation, can guarantee primary addition sufficient amount
Dust and even suction system meet test needs, reduce labour cost；The utility model is completed using above-mentioned several components
The building of this device, structure is simple, significantly reduces experimentation cost；It is close that the utility model can carry out most of dust
The test of envelope property, and efficiency is improved, and reduce costs.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical new to this
The range of type is defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel pair
The various changes and improvements that the technical solution of the utility model is made should all fall into claims determination of the utility model
In protection scope.
