Military-standard Dust Chamber
Technical Parameter
Operating chamber(mm):1000*1000*1000(D×W×H)
Structure and material:
Design principle:
Its structure is a funnel,a collecting hole for dust on the bottom,on the right side of this hole is equipped with a suction inlet of turbine circulating fan.Send the pumped dust into the bottom of inner chamber and then to the left side and go upwards;blow the dust into test chamber from the left side; the dust should be blown rightwards in a horizontal direction and then begin circulation(shown as above picture).
Material and Configuration
1.Internal material:sus304 stainless steel
2.External material:stainless steel
3.big Transparent window on the door is convenient to observe specimen during testing;
4.unique air channel design to ensure it produce laminar flow with concentration;
5. Blow fan adopts stainless steel shell, high sealing and wing speed, low noise;
Technical Parameter
1.fine dust:under 75um
2.coarse dust:under 150um
3.Dust concentration:5G/m³±1.5
4.Flow speed:10-20m/s±1.5(adjustable)
5.Using amount of quartz powder:5kg/ m³( 70 % quartz sand, 15 % chalk dust, 15 % kaolin)
Control System
1.PLCand touch screen intelligent control system
2.PT100 test sensor
3. dust concentration meter
4.anemometer(portable)adjust air speed before testing
5.over temp. Protection on instrument
6.Phase loss protection
7.Circuit breaking protection against current leakage
8.power:AC380 V 50Hz
9.door: tempered glass
10. vacuum pump 60-600L/H
11. pressure regulating valve,uction nozzle,three pieces of pressure regulating
12. controller:programmable controller(it has below control functions which can be arbitrarily set)
a. blowing dust time(stop,blow)h/m/s adjustable
b. cycle period:arbitrarily adjustable
c. preset testing time:0s~999h99m99s arbitrarily adjustable
d. Power on:off—on—off
metal screen mesh size:nominal wire diameter 50um,line-to-line; spacing 75um or under 150um
Fan:PE centrifugal fan
Note:this test can meet requirements of household appliance,low voltage apparatus,automobile,motor components and outer housing protection in GB2423,GB4706,GB4208 and DIN(5KG talcum powder will be thown in.)
