Detailed Description

Military-standard Dust Chamber Technical Parameter Operating chamber(mm):1000*1000*1000(DWH) 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 1Internal material:sus304 stainless steel 2External material:stainless steel 3big obsevation window on the door 4unique air channel designto ensure it produce laminar flow with concentration; Technical Parameter 1fine dust:under 75um 2coarse dust:under 150um 3Dust concentration:5G/m1.5 4Flow speed:10-20m/s1.5(adjustable) 5Using amount of quartz powder:5kg/ m( 70 % quartz sand, 15 % chalk dust, 15 % kaolin) Control System 1PLCand touch screen intelligent control system 2PT100 test sensor 3. dust concentration meter 4anemometer(portable)adjust air speed before testing 5over temp.
