Description
Technical Field
The invention relates to the technical field of test equipment, in particular to a device and a method for testing air filtering air flow and packaging performance.
Background
Automobile filter is the effect of filtering impurity or gaseous, and more common automobile filter has: air filters, air-conditioning filters, oil filters, fuel filters, each of which filters substantially air or liquid impurities. The automobile filter has high filtering performance; the service life is long; the durability and the vibration performance are high, and dust cannot leak; water resistance, no blockage of air, simple and light loading and unloading. The application of the automobile filter comprises the following aspects: (1) automobile filter is special protection driver's personnel, and air conditioner filter can filter pollen, dust, harmful substance in the outside air, if: asbestos, soot, bacteria and toxic gases, such as: ozone, benzene, toluene, and the like; (2) keeping the relevant parts clean: the air conditioner filter can keep the following parts clean, such as: fans, heating and dashboard, etc.; (3) activated carbon automotive filter: it is different from general air-conditioning filter in that it has more than one active carbon filter layer to further absorb toxic gas, such as: ozone, nitrogen oxides, sulfur, and hydrocarbons.
After the automobile filter is used for a period of time, the air permeability of the automobile filter can be changed, the air permeability of the automobile filter cannot be judged by naked eyes, and a special test device for the air permeability of the automobile filter does not exist at present, so that inconvenience in work is brought to automobile production and maintenance manufacturers. The invention provides a device for testing air filtering flow and packaging performance, which can quickly detect the air permeability of an automobile filter, has certain guiding significance for automobile production and maintenance manufacturers, and is more favorable for the use safety of users.
