Description
Technical field
The present invention relates to test equipment technical field, the air permeability experimental rig of specifically a kind of automobile filter and detection
Method.
Background technology
Automobile filter, is the effect of impurity screening or gas, and relatively common automobile filter has：Air-filtering
Device, air-conditioning filter cleaner, oil filter, fuel filter, each corresponding filter were substantially air filtering or liquid
The impurity of body.Automobile filter strainability is high；Service life is permanent；Durable vibratility, durability are high, will not leak dust；It is resistance to
It is aqueous, the entrance of air will not be blocked, handling are simple light and handy.The application of automobile filter includes the following aspects：(1) automobile
Filter is special protection driving staff, and air-conditioning filter cleaner can filter out pollen in outside air, dust, harmful substance,
Such as：Asbestos, coal smoke, bacterium and toxic gas, such as：Ozone, benzene and toluene etc.；(2) cleaning of associated components is kept：Air-conditioning filtering
Device can keep the cleaning of lower section parts, such as：Fan, heating and instrument board etc.；(3) activated carbon automobile filter：It and it is general
The difference of air-conditioning filter cleaner is more one layer of active carbon filtration layer, further absorbs toxic gas, such as：Ozone, nitrogen oxide, sulphur
And hydrocarbon.
In use for some time, air permeability can change automobile filter, cannot judge that automobile is filtered using naked eyes
The air permeability of clear device, at present also without the experimental rig of the special air permeability for automobile filter, therefore, to automobile production
The inconvenience in work is brought with repair producer.The present invention provides a kind of air permeability experimental rigs of automobile filter, can be fast
Speed detects the air permeability of automobile filter, and has certain directive significance for automobile production and man of maintenance factory, also more
Added with the safety used conducive to user.
Invention content
The problem to be solved in the present invention is：Overcome the deficiencies of the prior art and provide a kind of simple in structure, equipment volume is small,
The air permeability of automobile filter can be quickly detected, and there is certain guidance to anticipate automobile production and man of maintenance factory
Justice is also more conducive to the air permeability experimental rig of the automobile filter for the safety that user uses.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of air permeability experiment of automobile filter
Device, including import pressure-measuring pipe, the outlet pressure-measuring pipe and absolute filter from top to bottom set gradually, the import pressure-measuring pipe
A filter material is equipped between bottom end and the top for exporting pressure-measuring pipe, the top of the import pressure-measuring pipe connects a dust injector, institute
It states and a dust tray is connected on dust injector, the bottom end of the import pressure-measuring pipe and the top for exporting pressure-measuring pipe and same inclined tube pressure
Power machine connects, and the bottom of the absolute filter connects an air exhauster.
Further, the top of the import pressure-measuring pipe is connect by a dust playpipe with dust injector.
Further, the dust tray is connect by a suction dust pipe with dust injector.
Further, it is also connected with an air pressure regulator on the dust injector.
Further, the absolute filter is connect by an exhaust tube with air exhauster.
Further, the exhaust tube is equipped with flow meters.
Further, the filter material is filter paper or filter cloth.
The invention has the advantages and positive effects that：
The air permeability experimental rig of automobile filter of the present invention, simple in structure, equipment volume is small, can quickly detect vapour
The air permeability of vehicle filter, and there is certain directive significance for automobile production and man of maintenance factory, also it is more conducive to use
The safety that family uses.

Specific embodiment
As shown in Figure 1, a kind of air permeability experimental rig of automobile filter, the import including from top to bottom setting gradually is surveyed
Pressure pipe 1, outlet pressure-measuring pipe 2 and absolute filter 3, are equipped with one between the bottom end of import pressure-measuring pipe 1 and the top for exporting pressure-measuring pipe 2
Filter material 4, filter material 4 are filter cloth, and the top of import pressure-measuring pipe 1 connects a dust injector 6, dust spray by a dust playpipe 5
Dust pipe 7 being inhaled by one in emitter 6 and connecting a dust tray 8, an air pressure regulator 9, import pressure measurement are also connected on dust injector 6
The bottom end of pipe 1 is connect with exporting the top of pressure-measuring pipe 2 with same inclined tube forcing press 10, and the bottom of absolute filter 3 is taken out by one
Tracheae 11 connects an air exhauster 12, and exhaust tube 11 is equipped with flow meters 13.
The course of work of the present embodiment：
Filter is placed in import pressure-measuring pipe 1, is exported on pressure-measuring pipe 2, and fixed with fixture, starts dust playpipe
