Dab tsi yog Foam Bladder Tank?
Foam Bladder Tank yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob ruaj khov. Nws yog tsim los ntawm steel siab lub nkoj uas muaj cov roj hmab zais zis. Qhov chaw nruab nrab ntawm lub zais zis thiab lub plhaub tank yog ntim nrog cov npuas dej kom zoo, thaum cov dej hauv siab nkag mus rau hauv lub zais zis, nyem cov concentrate tawm mus rau hauv proportioner (xws li Venturi lossis balanced pressure device). Qhov no tsim kom muaj qhov sib xyaw ua npuas dej-rau-dej sib tov rau Class B (flammable kua) thiab Class A hluav taws.
Foam zais zis tso tsheb hlau luam muab txhim khu kev qha, txij nkawm-phooj ywg ua npuas ncauj proportioning yam tsis xav tau lub zog sab nraud. Lawv tau dav siv nyob rau hauv cov roj refineries, tshuaj nroj tsuag, aircraft hangars, thiab marine terminals. Qhov ntau thiab tsawg ntawm 100 litres mus rau ntau tshaj 20,000 litres, haum rau ntau hom ua npuas ncauj (AFFF, AR-AFFF, protein, thiab lwm yam). Lub kaw lus xyuas kom meej tias cov npuas dej yog ib txwm cais tawm ntawm dej kom txog thaum tso tawm, tiv thaiv degradation.
Qhov tseeb proportioning (feem ntau 1%, 3%, lossis 6%)
Tsis xav tau lub zog sab nraud - kev ua haujlwm hydraulic
Ntev concentrate lub neej (lub zais zis cais los ntawm dej)
Txhim khu kev sib piv
Khaws qhov sib piv (± 10%) dhau qhov dav dav (20-100% ntawm cov ntsuas ntws).
Kev kho qis
Lub zais zis tuaj yeem hloov tau yog tias puas lawm; Cov chaw kuaj xyuas sab nraud muaj.
Versatile Installation
Kab rov tav los yog ntsug qauv haum rau feem ntau cov twj tso kua mis thiab skid-mounted systems.
Ntiaj teb no Standards
Tsim los rau NFPA 11, EN 13565-2, thiab ISO 7076-3.
Hom FOREDE Foam Bladder Tanks
Cov kab mob zais zis sib txawv sib txawv raws li qhov xav tau kev tiv thaiv hluav taws sib txawv, los ntawm cov khoom me me mus rau qhov chaw cia khoom loj.
Vertical Foam Bladder Tank
Vertical zais zis tso tsheb hlau luamyog cov feem ntau configuration rau tsau ua npuas ncauj tshuab. Lawv tuav cov hneev taw me me, ua rau lawv zoo tagnrho rau chav twj tso kua mis lossis cov ntaub thaiv npog. Peev xwm ntawm 200 mus rau 10,000 litres. Cov qauv ntsug tso cai yooj yim rau lub zais zis kuaj ntawm sab saum toj manway. Lawv feem ntau yog siv nrog lub zais zis tank proportioners (sib npaug siab) thiab muaj peev xwm pab tau ntau yam ua npuas ncauj tawm (saib, nozzles, ua npuas ncauj chamber).
FOREDE ntsug tso tsheb hlau luam muaj cov roj hmab zais zis (lossis EPDM rau dej cawv-resistant), stainless hlau dej inlet / qhov hluav taws xob, thiab lub ntsuas siab. Lub plhaub tank yog carbon hlau nrog epoxy txheej.
Kab rov tav Foam Bladder Tank
Kab rov tav lub zais zis tso tsheb hlau luam are chosen when vertical height is limited, such as in mobile foam units or low‑clearance skids. They are also common for large capacities (>10,000 litres) qhov twg lub tank ntsug yuav siab dhau. Lub zais zis thiab proportioning txoj cai tseem zoo tib yam.Kab rov tav tankstej zaum yuav xav tau kev txhawb nqa ntxiv thiab cov kav dej tab sis muab tib qhov kev faib ua feem raws li hom ntsug.
Cov tso tsheb hlau luam no feem ntau muab tso rau hauv kev sib tw ua npuas dej lossis cov chaw ua haujlwm sab nrauv uas qhov chaw muaj kev txwv. FOREDE muab kev cai-tsim cov kab rov tav tso tsheb hlau luam nrog nqa lub log thiab lub siab nyem li qub.
Yuav Ua Li Cas Xaiv Lub Nrawm Lub Ncauj Tank
Kev xaiv kom raug ua kom ntseeg tau tias ua npuas ncauj sib npaug thiab ua raws li cov lej hluav taws.
Thaum xaiv lub zais zis ua npuas ncauj, xav txog cov hauv qab no tsis:
Yuav tsum tau ua npuas ncauj concentrate ntim- Raws li thaj chaw muaj kev phom sij, qhov paug tawm, thiab lub sijhawm (NFPA 11 yam tsawg kawg 15-30 feeb).
Kev sib piv- 1%, 3%, lossis 6% nyob ntawm hom ua npuas ncauj thiab daim ntawv thov.
Kev khiav hauj lwm siab- yuav tsum sib phim dej (feem ntau 6-12 bar).
Cov khoom siv zais zis- nitrile rau tus qauv AFFF, EPDM rau dej cawv-resistant ua npuas ncauj.
Kev sib txuas loj- 2 ", 3", 4 "los yog loj dua proportioner.
Daim ntawv pov thawj- UL, FM, CE, lossis kev pom zoo hauv hiav txwv. Kuj txiav txim siab ntawm ntsug lossis kab rov tav orientation raws li qhov chaw muaj.
Ua npuas ncauj concentrate ntim: 200-20, 000+ litres
Qhov sib piv: 1%, 3%, 6% (taw lossis teb-adjustable)
Lub zais zis khoom compatibility nrog ua npuas ncauj hom
Ua haujlwm siab tshaj plaws (PN10 txog PN16)
Kev taw qhia: ntsug (tus qauv) lossis kab rov tav
Cov ntawv pov thawj: NFPA, EN, UL, FM, marine class
Daim ntawv thov ntawm Foam Bladder Tanks
Bladder tank systems raug xa mus rau txhua qhov chaw uas cov hluav taws kub hluav taws kub muaj kev pheej hmoo, nrog rau qee yam kev phom sij rau Class A.
Cov khoom siv roj & roj(refineries, tank farms, loading racks) siv lub zais zis tso tsheb hlau luam los tiv thaiv cov tso tsheb hlau luam thiab chaw ua haujlwm.
Cov nroj tsuag tshuajtuav polar solvents yuav tsum tau AR-foam tshaj lub zais zis.
Aircraft hangarsmuaj kev tiv thaiv los ntawm lub zais zis uas muaj peev xwm noj cov tshuaj ua npuas ncauj thiab cov hauv qab nozzles (ib NFPA 409).
Kev tsim hluav taws xob(coal conveyors, turbine enclosures) siv tsawg-expansion ua npuas ncauj.
Kev siv dej hiav txwvsuav nrog LNG cov cab kuj, roj tankers, thiab offshore platforms.
Heliportsthiabtunnel drainage systemskuj cia siab rau lub zais zis tank proportioning.
Piv nrog rau cov twj tso kua mis tsav, lub zais zis tso tsheb hlau luam muaj kev ntseeg siab - lawv xav tau tsis muaj hluav taws xob, tsuas yog dej siab. Qhov no ua rau lawv zoo tagnrho rau cov chaw taws teeb lossis kev txhim kho siab.
Foam Bladder Tank FAQ
Q1: Ua li cas lub zais zis tank ua haujlwm?
A: Cov dej nyob rau hauv siab nkag mus rau hauv lub zais zis tank, nyem lub zais zis hloov tau uas muaj cov ua npuas ncauj concentrate. Cov concentration yog yuam tawm los ntawm ib qho proportioner (venturi lossis balanced pressure device) uas txhaj nws mus rau hauv cov dej ntws ntawm qhov feem pua (1%, 3%, lossis 6%). Tsis tas yuav muaj hwj chim sab nraud.
Q2: Lub neej ntev ntawm lub zais zis yog dab tsi?
A: Nrog kev saib xyuas kom zoo thiab huv si, lub zais zis nitrile lossis EPDM tuaj yeem kav 10-15 xyoo. Lub zais zis yuav tsum tau tshuaj xyuas txhua xyoo rau cov kab nrib pleb, softening, lossis o. Kev hloov pauv yog ncaj qha thiab tsis tas yuav hloov tag nrho lub tank.
Q3: Tib lub tank puas tuaj yeem siv rau ntau hom ua npuas ncauj?
A: Tsuas yog tias cov khoom siv zais zis tau sib haum nrog txhua qhov ua npuas ncauj (xws li, EPDM ua haujlwm nrog AFFF thiab AR-AFFF). Txawm li cas los xij, kev sib kis kab mob tuaj yeem ua rau ua npuas ncauj ua haujlwm. Nws yog qhov zoo tshaj plaws los muab lub tank rau ib hom ua npuas ncauj thiab yaug kom huv si ua ntej hloov.
Q4: Kuv tuaj yeem tau txais qhov kev txiav txim li cas?
A: zais zis tank + venturi proportioner: ± 10-15% tshaj 25-100% ntws ntau. Lub zais zis tank + sib npaug siab proportioner: ± 5-10% tshaj 20-100% ntws ntau. FOREDE systems ua tau raws li NFPA 11 qhov yuav tsum tau ua kom raug rau cov tshuab ruaj khov.
Q5: Kuv yuav loj npaum li cas lub zais zis tank?
A: Xam tag nrho cov npuas dej xav tau=(tus nqi thov) × (tiv thaiv cheeb tsam) × (ntev sijhawm). Rau lub tank pob, tus nqi raug yog 6.5 L / min / m² rau 30-60 min. NFPA 11 muab cov txheej txheem tsim kom ntxaws. FOREDE muab kev pabcuam pub dawb - muab hom phom sij, thaj chaw, thiab hom ua npuas ncauj.
Q6: Yuav tsum muaj kev saib xyuas dab tsi?
A>: Kev tshuaj xyuas txhua xyoo ntawm lub tank sab nrauv, ntsuas qhov siab, thiab cov kav dej. Kev kuaj lub zais zis txhua txhua 3-5 xyoos (los yog ib tus lej hauv zos). Foam concentrate sampling per NFPA 11 (ib xyoos ib zaug). Hloov cov concentrate yog tias kev kuaj tsis tau. FOREDE muab cov khoom siv tu thiab kev txhawb nqa.
