Utility model content
The purpose of this utility model is to provide a kind of civil air defense constructions and installations oil network filter capability pick-up unit, accurately can detect the performance of civil air defense constructions and installations oil network filtrator, by measuring drag characteristic, dust containing capacity and arrestance efficiency, and its filter effect of understanding directly perceived.
The purpose of this utility model is achieved in that a kind of civil air defense constructions and installations oil network filter capability pick-up unit, comprise terminal filter and filtrator to be measured, described terminal filter and filtrator to be measured are disposed in testing conduit successively, respective ends filtrator and filtrator to be measured are provided with the first pressure gauge and the second pressure gauge to the outer wall of testing conduit respectively, testing conduit is connected with powder producer near one end of filtrator to be measured, the other end of powder producer is corresponding with air compressor to be connected, the other end of described testing conduit is connected with Venturi tube, the outer wall correspondence of Venturi tube is provided with Venturi meter, the other end of described Venturi tube is connected with blower fan.
When the utility model uses, first start blower fan, according to the reading of Venturi meter, adjust and be respectively 50%, 75%, 100% and 125% of nominal air delivery by the air quantity of filtrator to be measured, in conjunction with the second manometric reading, obtain air quantity resistance curve, when measuring dust containing capacity and arrestance efficiency, first weigh the quality of terminal filter and filtrator to be measured, be installed into again in testing conduit, guarantee that installation place is without leakage, start blower fan, weigh the quality of manmade dust, air compressor is by manmade dust press-in testing conduit in powder producer, manmade dust is through filtrator to be measured, remaining manmade dust is trapped by terminal filter, take out terminal filter again and filtrator to be measured weighs its quality respectively, the manmade dust quality that filtrator to be measured traps when reaching whole resistance is dust containing capacity, the ratio of the control of dust amount and powder amount that calculate filtrator to be measured is arrestance efficiency.Compared with prior art, the beneficial effects of the utility model are: by detecting drag characteristic, dust containing capacity and arrestance efficiency, intuitively can understand strainability and the effect of civil air defense constructions and installations oil network filtrator.This apparatus structure is simple, and automaticity is high, and accuracy of detection is high, and the manmade dust sent is vaporific dirt, and environmental protection and energy saving are pollution-free.
As further improvement of the utility model, between described Venturi tube and blower fan, be also provided with transition conduit.
As further improvement of the utility model, the manmade dust concentration that described powder producer sends is 63 ~ 77mg/m
