Description
Technical field
This utility model is related to wind quantity test device, more particularly to a kind of wind quantity test device for air purifier.
Background technology
Indoor air quality greatly affects quality of life, health level and the production efficiency of people.And China
Domestic air pollution is on the rise, only 5 city PM2.5 annual means in data display national 74 main cities in 2013
Reach below 35 micrograms/cubic meter, and contemporary mankind accounts for very big ratio the time indoors in environment, now room air
Purification just seem and be extremely necessary.
Facing to so severe outdoor environment, indoor air cleaner becomes the popular choosing of control IAQ (indoor air quality)
Select.The operation principle of air purifier is the dirt that active convective is crossed in the air of blower fan by the use of blower fan as air flow power
Dye thing is carried out filtering, is adsorbed, decomposition and inversion etc. is processed, so as to improve room air cleanliness factor.For air purifier purification is imitated
The measurement of fruit typically adopts pure air conveying capacity (CADR), and the purification assembly constant for efficiency, air quantity are to affect CADR
Key parameter, therefore accurately the air quantity of measurement depurator becomes necessary.
Problem present on outlet air quantity testing method in depurator is at present：
Depurator air outlet need to be placed in a segment pipe by the GB pipeline method of testing that manufacturer typically takes, the method
In, length of pipe section should be 1.1 times of test purifier length, and be not less than 1m, need to handle pipeline section and depurator well in test
Between sealing, therefore this mode experimental facilitiess and condition are excessively complicated.
" wind speed × area-method " that each laboratory is generally adopted, this kind of method is fast and simple, but filter outlet section
Wind speed profile is extremely irregular, and this brings difficulty for multimetering wind speed, also makes result more inaccurate.Existing patent is such as
Disclosed in " air conditioner refrigerating air output test device ", 205449188U disclosed in 202939051U " air-conditioning system
The measurement fan housing in air diffuser circle air port ", is the wind quantity test device of air-conditioning device, and certainty of measurement is not high, is not directed to
The system of actually used middle air purifier wind quantity test.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided one kind improves test accuracy and close
The good wind quantity test device for air purifier of sealing property.
A kind of wind quantity test device for air purifier of the present utility model, including air channel, in described air channel
One end is fixedly linked with hose connector and fiber cloth connector successively by necking down reducing air port, in the another of described air channel
One end closing is fixed with end stop, along being provided with least one grid perpendicular to the direction of air channel axis in the described air channel
Cowling panel, described grid cowling panel frame are fixedly linked with air channel inwall, and multiple holes are provided with described end stop,
The nozzle flowmeter of different ranges is installed on described multiple holes, being connected with described fiber cloth connector end can
Fiber cloth connector is tightened into the scalable rope of setting.
The beneficial effects of the utility model are:At least one piece grid cowling panel is provided with air channel carries out rectification so that section
Even flow field, it is to avoid the uneven phenomenon of section VELOCITY DISTRIBUTION, improves test accuracy.Due to having installed rectification in air channel
Plate, substantially reduces the length in required air channel so that the more compact practicality of device.With filter air outlet using band fluid sealant
Bar is flexible coupling, it is adaptable to the air outlet of different specification size, is aided with sealing flexible rope reduction and leaks out possibility.Multiple aperture nozzle stream
Gauge structure, it is adaptable to the depurator wind quantity test of various air quantity shelves.
Description of the drawings
Fig. 1 is a kind of structural representation of wind quantity test device for air purifier of the present utility model；
Fig. 2 is the grid cowling panel schematic diagram in Fig. 1 shown devices.
Specific embodiment
This utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
A kind of wind quantity test device for air purifier of the present utility model, including air channel 7 as shown in drawings,
The one end in described air channel 7 is fixedly linked with hose connector 2 and fiber cloth connector 1 successively by necking down reducing air port 3,
Other end closing in described air channel 7 is fixed with end stop, along perpendicular to the side of 7 axis of air channel in described air channel 7
To at least one grid cowling panel is provided with, described grid cowling panel frame is fixedly linked with 7 inwall of air channel, at described end
Multiple holes are provided with end-stopping plate, the nozzle flowmeter 6 of different ranges are installed on described multiple holes, exhaust passage can be measured
Interior air quantity summation, so as to be purified the air force of device, the number in hole is by tested air purifier air force and not
Determine with gear.It is connected with and fiber cloth connector 1 can be tightened setting in described 1 end of fiber cloth connector
Scalable rope.
Described hose connector 2 can be fixed using glued seals with fiber cloth connector 1, and described fiber cloth connects
Interface 1 can be adjusted according to different depurator air outlet sizes to be measured, and air port is completely covered.Hose connector 2 can be adopted
Fiber cloth or plastic material.
Fiber cloth connector 1 when in use, is wrapped the air outlet after-drawing end of depurator to be measured, is made by this structure
Obtain cloth to be in close contact with depurator air outlet, while winding sealing joint strip in seam, it is to avoid leak out.
Hose connector 2 can be random adjustment angle, it is adaptable to various forms of depurators, facilitate the measurement of tester,
Necking down reducing air port 3 causes depurator to export uneven flow field using reducing air port and obtains preliminary rectification.Grid cowling panel is
Fairing in air channel so that by the flow field of tester more uniform and stable, improves certainty of measurement.
The installation method and the course of work of this device be：Twice grid cowling panel 4,5 is installed in air channel before test, and
According to the air quantity of tested air purifier, (air quantity is bigger, 6 number of nozzle flowmeter for the nozzle flowmeter 6 of installation corresponding number
It is more).Fiber cloth connector 1 is connected with air purifier air outlet (being not drawn in figure) to be measured, and is pricked with scalable rope
Tight port, it is ensured that sealing.Depurator is opened, the registration of nozzle flowmeter 6 after flow field is steady, is read, is carried out data acquisition.
