Qhov zoo thiab qhov tsis zoo ntawm qhov sib txawv ntawm lub siab ntws ntsuas

Qhov zoo:
(1) Feem ntau siv orifice phaj flowmeter muaj cov qauv ruaj khov, ruaj khov thiab txhim khu kev qha, thiab lub neej ua haujlwm ntev;
(2) Muaj ntau hom kev siv, thiab txog tam sim no tsis muaj hom flowmeter uas tuaj yeem muab piv rau nws;
(3) Cov khoom kuaj pom, cov khoom xa tawm, thiab cov cuab yeej tso saib yog tsim los ntawm cov tuam txhab sib txawv, uas pab txhawb kev lag luam ntawm kev tsim khoom.
Qhov tsis zoo:
(1) Kev ntsuas qhov tseeb feem ntau yog qis;
(2) Qhov ntau yog nqaim, feem ntau tsuas yog 3: 1 txog 4: 1;
(3) Cov kev xav tau siab rau kev teeb tsa ntawm qhov chaw;
(4) Kev poob siab siab (xa mus rau daim phiaj orifice, nozzles, thiab lwm yam).
Lus Cim: Ib yam khoom tshiab: lub ntsuas dej sib npaug tsim los ntawm NASA, uas muaj qhov ntsuas qhov tseeb 5-10 npaug ntawm cov khoom siv throttling ib txwm muaj thiab qhov poob siab tas li ntawm 1/3. Lub siab rov qab yog ob zaug sai dua, thiab qhov tsawg kawg nkaus cov yeeb nkab ncaj nraim tuaj yeem ua me me li 1.5D. Nws yog ib qho yooj yim rau nruab thiab siv, zoo heev txo kev noj cov kua dej ua haujlwm muaj peev xwm.
