Dab tsi yog nyob rau hauv kab ua npuas eductor
Tus Inline Foam Eductor yog qhov tseem ceeb hauv kev ua npuas ncauj tsim los ua npuas dej kom haum rau cov dej khov kho, tsim hluav taws kub {{0} suppressing ua npuas. Qhov kev ua haujlwm passive no ua haujlwm tsis muaj zog sab nraud, cia siab ib leeg ntawm cov hauv cov kab ke ntawm cov kab ke ntawm cov kua hluav taws xob tsis zoo kom ua tiav cov kev ua ntu zus. Dav siv hauv kev lag luam, kev tiv thaiv hluav taws, hauv kev tiv thaiv hluav taws kub rau cov roj av uas cuam tshuam nrog roj av, roj, thiab cov kuab tshuaj. Hauv qab no yog cov ncauj lus kom ntxaws txog lawv cov cai ua haujlwm, tsim cov yam ntxwv, zoo, thiab kev siv.
Cov tub ntxhais tseem ceeb ntawm tus kab ntxwv ua npuas dej yog raws li lub ventricenon uas cov kua dej ntawm cov yeeb nkab, ua rau muaj kev sib raug zoo hauv lub siab. Qhov kev txiav tawm no tsim lub tshuab nqus tsev uas rub npuas ua npuas ncauj kom zoo siab los ntawm cov khoom ntim sab nraud rau hauv dej ntws. Cov txheej txheem nthuav tawm hauv peb theem:
1.1 CEDMATION TOJ
Cov dej tso tawm nkag mus rau tus Eductor los ntawm ib qho inlet thiab hla dhau ntawm txoj kev nqaim lossis orifice. Qhov txo qis hauv tus ntoo khaub lig {{1} Ntu hauv cheeb tsam cov dej kom ua kom nrawm dua, raws li bernoulli txoj kab zauv). Piv txwv li, tus kws tshaj lij tsim tsim rau 100-300 GPM (nkas loos (nkas loos ib feeb) ntws mus rau lub siab los ntawm 20-30 psi ntawm lub caj pas, tsim kev ua npuas dej txaus rau kev ua npuas ncauj.
1.2 induction theem
Lub tshuab nqus tsev ntawm lub caj pas txav ua npuas ncauj ua npuas ncauj los ntawm cov thawv sib txuas ntawm cov raj nqa khoom lossis ceg yeeb nkab. Tus ntws ntws ntawm cov npaus yog tswj los ntawm kev kho cov orifice los yog metering Valve, tso cai ua ntu zus. Cov sib xyaw sib xyaw sib xyaw muaj xws li 1%, 3%, lossis 6%, nyob ntawm ua npuas ncauj (piv txwv li, protein ua npuas ncauj, lossis fluoroprourin foam) thiab hluav taws kub hnyav. Piv txwv li, tus eduction 3% yuav qhia 3 qhov chaw ua npuas dej zoo rau 97 ntu dej, ua kom muaj txiaj ntsig zoo ntawm hluav taws kub tsis muaj wastage.
1.3 sib xyaw thiab tso tawm theem
Tom qab kev tshawb nrhiav, cov npaus nti nkag rau hauv seem lossis sib xyaw Chamber, qhov chaw uas dej ntws nthuav dav, maj nrawm thiab nce siab. Cua hlob hauv cov chamber no ua kom muaj kev sib xyaw ua npuas dej kom huv si thiab dej ua homogeneous. Ua npuas ncauj ua ntej yog tom qab ntawd tawm ntawm qhov hluav taws xob rau cov khoom siv dej zoo li cov hoses, nozzles, lossis saib. Qee cov Advanced Eductors sib txuas nrog cov makic matic permers lossis baffles los txhim kho cov kev sib txuam, txawm tias muaj siab} viscosity conventrates.
2.1 Kev Ua Haujlwm Caij Nyoog
Inline foam edam order yuav tsum tsis muaj lub zog sab nraud, ua rau lawv ntseeg tau tias muaj xwm txheej ceev uas yuav swb. Lawv ua haujlwm thoob plaws ntau qhov kev siab (piv txwv li, 50-200 psi), yoog raws cov khoom siv dej sib txawv, cov twj hluav taws kub, lossis cov tsheb thauj khoom kub.
2.2 Kho tau kev kho kom haum
Niaj hnub nimno Eductors Cov kev tswj hwm niaj hnub no lossis ntsuas lub taub hau nrog yooj yim {nyeem cov pob qhov rooj lossis hu rau teeb tsa cov kev ua npuas dej. Qhov kev hloov pauv no tso cai rau cov neeg tua hluav taws rau kev daws teeb meem daws teeb meem tshwj xeeb:
Tsawg -} Kev nthuav dav ua npuas (1:10 txog 1: 200 qhov kev nthuav dav): Siv tau zoo rau hydrocarbon nchuav thiab hluav taws kub.
Siab -} mus rau 1: 1000 expansion piv): zoo tagnrho rau cov chaw uas zoo li cov chaw ua haujlwm lossis cov dav hlau hangars.
2.3 durability thiab corrosion tsis kam
Tsim los ntawm cov ntaub ntawv xws li Stainless hlau, tooj dag, lossis nyuaj -} anodized txhuas, eductors walls ib puag ncig. Qee cov qauv, xws li Akron tooj dag los ua npuas dej, siv cov copper alloy rau peb npaug rau cov qauv hlau, ua kom muaj zog hauv cov chaw hauv corrosive.
2.4 Kev Xa Khoom Portility thiab Rai Kev Xa Khoom
Kev cog lus sib xyaw, piv txwv li, 30% kev sib zog dua li cov kev xaiv hlau) thiab nrawm}} tso cov kauj vab ua kom ceev. Portable eductors tuaj yeem nqa los ntawm cov neeg tua hluav taws lossis mounted on skids rau cov ntawv thov mobile, thaum cov qauv sib xyaw ua ke rau hauv cov tshuab sib xyaw ua ke rau kev teeb tsa kev sib dhos.
Inline ua npuas xab eductors yog ntau yam, txhawb nqa:
3.1 Kev tiv thaiv hluav taws
Siv nyob rau hauv kev ua kom huv, tshuaj chemical, thiab cov chaw ntim roj rau txhawm rau txhawm rau txhim kho hluav taws kub. Piv txwv li, 6% Eductor yuav tiv thaiv tus diesel tank ua liaj ua teb kom ua rau cov picking tuab kom cais tawm cov oxygen.
3.2 Kev tua hluav taws
Ua ke rau hauv cov tsheb tua hluav taws lossis cov tshuab hluav taws xob rau cov lus teb ceev ceev rau tsheb hluav taws kub, hluav taws kub tsheb, lossis nchuav. Portable eductors cia cov neeg tua hluav taws kom txuas ncaj qha rau cov nyiaj npib lossis cov tsheb thauj khoom, txawm tias nyob hauv thaj chaw deb.
3.3 Aviation thiab Cov Tub Rog Tub Rog
Siab -} Kev nthuav dav rau cov neeg ua npuas ncauj rau cov dav hlau thiab hluav taws xob hluav taws xob, qhov chaw ua npuas dej nrawm yog xav tau los npog thaj chaw loj. TusSkum Foam Eductor, piv txwv li, muab cov Fluns ntws mus txog 1,200 GPM rau cov ntawv thov Maritime.
3.4 Wildland Firefighting
Lub teeb yuag, hnab ev ntawv {{0} mounted cov neeg tua hluav taws ua kom muaj hluav taws xob ua kom muaj hluav taws xob, txhim kho hluav taws kub hauv hav zoov lossis av hluav taws.
