Izinga leziQiniseko ze-FM leziGcini Zamanzi: Umhlahlandlela weziNjinini neziQinisekiso
Kwadalwa ngo Ngokwamukisa
I-FM Approvals Standard for Water Storage Tanks: Umhlahlandlela Wezobunjiniyela Nokuhambisana
I-FM Approvals, isikhungo sokuhlola esizimele senkampani yomshwalense yamazwe omhlaba i-FM Global, ikhipha esinye sezitifiketi eziqinile futhi ezihlonishwa emhlabeni wonke zemikhiqizo yokuvimbela ukulahleka kwempahla. Emkhakheni wezingqalasizinda zezimboni, i-FM Standard 4020 ilawula ukuklama nokukhiqizwa kwamathangi ensimbi ukuze kuvikelwe umlilo. Ngokungafani nokugcinwa kwamanzi komasipala okujwayelekile, ithangi eliqinisekiswe yi-FM lenziwa ngaphansi komqondo "wokuhluleka okungazenzeki", liqinisekisa ukuthi uhlelo lokucisha umlilo lwesikhungo lunezela amanzi angaphazamiseki, aqinisekisiwe phakathi kokuphuthuma okukhulu.
1. Ububanzi Be-FM Standard 4020
Ngenkathi amazinga njenge-AWWA D103-09 echaza ukugcinwa kwamanzi ngokujwayelekile, i-FM 4020 ihlola ngokukhethekile amathangi okudonsa imishini yomlilo. Lawa ngamanqolobane anikezelwe anikezela izinhlelo ezizenzakalelayo zokufafaza zesikhungo kanye nemishini yomlilo.
Ukuze uthole i-FM Approval, umenzi wethangi kufanele afakaze ukuthi imiklamo yethangi labo, izinto zokwakha, nezindlela zokubala zihlangabezana nezimfuneko eziqinile kuzo zonke izindawo:
● Ubuqotho Bokwakhiwa: Ithangi kufanele likwazi ukumelana nemithwalo emikhulu yemvelo ngaphandle kokugoba noma ukuwa.
● Ukwethembeka Kwama-Hydraulic: Ithangi kufanele livumele ukudonswa kwamanzi ngokushesha, ngaphandle kwesithiyo, ngemishini yomlilo enomthamo omkhulu.
● Ikhwalithi Yokukhiqiza: Umakhi kufanele adlule ezivivinyweni eziqinile, eziqhubekayo zezindawo ukuze kuqinisekiswe ukulawulwa kwekhwalithi okungaguquki ezinqubweni zokushisela, ukubopha, nokugqoka.
2. Izidingo Ezibalulekile Zobunjiniyela
Ithangi lomlilo eliqinisekiswe yi-FM lifuna izici ezikhethekile zobunjiniyela eziluhlukanisa namathangi ajwayelekile amanzi okuphuza noma amanzi angcolile.
A. Amapuleti Angavimbeli i-Vortex (Abavimbeli be-Vortex)
Lapho iphampu yomlilo enamandla amakhulu idonsa amanzi ethangini, ingadala i-vortex (isiphepho samanzi). Uma le i-vortex ifinyelela ku-suction pipe, ingena umoya kuphampu yomlilo, ibangele i-cavitation nokwehluleka okusheshayo kwephampu. Izinga le-FM 4020 liyala usayizi kanye nokubekwa okunembayo kwe-anti-vortex plate esindayo phezu kwe-suction nozzle ukuze kuqinisekiswe ukudonswa kwamanzi okungu-100% kuye ezingeni eliphansi kakhulu.
B. Imithwalo Yezakhiwo Eyenziwe Ngaphezu Kwesidingo
Amathangi omlilo akumele wehluleke lapho edingeka kakhulu. Izibalo ze-FM zivame ukudlula izimiso zokwakha zasekhaya ze:
● Umsebenzi Wenyikima: Izibalo eziqinisiwe zokuhambisa amanzi kanye nezinhlelo zokubopha eziqinisiwe (ezivame ukudinga amabhawodi esisekelo esisindayo namaphaneli ensimbi amadala ezansi).
● Umoya neqhwa: Izakhiwo zophahla, njengophahla lwe-aluminum dome noma uphahla lwamaphaneli ayisicaba, kufanele zikwazi ukuthwala imithwalo enzima kanye nomoya onamandla ngaphandle kokulimaza ingaphandle lesitsha.
C. Izinhlelo Ezithile Zokufaka Amapayipi Nokungena
● Imigqa Yokudonsa Nokubuyisa: Usayizi nendawo kulawulwa ngokuqinile ukuze kuvinjelwe ukuhambisa amanzi ngaphakathi kwesitsha ngesikhathi sokuhlolwa kwamaphampu.
● Usayizi Womnyango Wokungena: Imingcele yophahla neyengaphandle kufanele ihlangane nezilinganiso ezithile zokuhlola okusheshayo nokungena okuphuthumayo ngabasebenzi bomnyango womlilo.
3. I-Matrix Eqhathanisayo: Izitsha Zomlilo Ezivunyelwe yi-FM vs. Izitsha Zamanzi Ezejwayelekile
Kubathengi bezinto kanye nabasabalalisi be-EPC (Engineering, Procurement, and Construction), ukuqonda umehluko phakathi kwethangi lamanzi elijwayelekile kanye nethangi lomlilo eliqinisekiswe yi-FM kubalulekile ukuze izindawo zihambisane nemithetho.
Isici | Ithangi Lomlilo Eliqinisekiswe yi-FM (Izinga 4020) | Ithangi Lamanzi Elijwayelekile (isb., AWWA) |
Inhloso Eyinhloko | Ukudonsa kwempompi yomlilo ephuthumayo | Ukudla kwansuku zonke komasipala/imboni |
I-Anti-Vortex Plate | Iyadingeka (Ilinganiswe ngokuqinile) | Ongakukhetha / Akuyona eyokujwayelekile |
Ukulinganiswa kwe-Venting | Kukhulu kakhulu (ukuze kubhekane nokudonswa okusheshayo kwempompi) | Ukulinganiswa okujwayelekile (kusekelwe ezingeni lokugcwalisa/lokukhipha) |
Izivivinyo Zokukhiqiza | Izivivinyo ezivame ukwenziwa, ezingaziswanga ze-FM ezindaweni | Umsabalalisi uzilawula ngokwakhe / ISO 9001 |
Umthelela Womshwalense | Kunciphisa kakhulu izimali zomshwalense wezindawo zokuhweba | Ayikho Inkinga |
4. Inzuzo Yokuhweba: Umshwalense kanye Nokunciphisa Ubungozi
Ngaphandle kokuqiniseka ngokwakhiwa, ukucacisa ithangi eligunyazwe yi-FM kuyisinqumo sezimali esihle. Ngoba i-FM Global ingumshisekeli wezindawo zokuhweba, izindawo ezisebenzisa ingqalasizinda egunyazwe yi-FM zibonisa ingozi encane yomlilo omkhulu ngokwezibalo.
● Ukuncishiswa kwezimali zomshwalense: Izindawo zokugcina izimpahla, izimboni, namahabhu ezokuthutha ezihlome ngezinhlelo zokuvikela umlilo ezigunyazwe yi-FM zivame ukufanelekela ukuncishiswa okukhulu ezimalini zomshwalense wezindawo zazo zokuhweba.
● Ukusheshisa okusemthethweni: Ezindaweni eziningi zomhlaba wonke, abaphathi bomlilo bendawo kanye nezikhulu zeGunyaziwe Elinamandla (AHJ) bazokwamukela ngokuzenzakalelayo ithangi eligunyazwe yi-FM ngaphandle kokudinga ukubuyekezwa okuningiliziwe kwezobunjiniyela besibili.
5. Imibuzo Evame Ukubuzwa (FAQ)
Q: Ingabe umkhiqizi wanoma yiziphi izitsha zensimbi eziboshiwe angakwazi ukuhlinzeka ngesitsha esigunyazwe yi-FM?
A: Cha. Umkhiqizi kufanele atshale kakhulu ukuze izibalo zakhe zobunjiniyela ezithile, ubukhulu bamaphaneli, nemiklamo yokuhlanganisa ihlolwe futhi iqinisekiswe yi-FM Approvals. Abakhiqizi abaluhlu lwe-FM Approval Guide kuphela abagunyaziwe ukuhlinzeka ngalezi zitsha.
Q: Ingabe i-FM 4020 isebenza kuphela ezitheni eziboshiwe?
A: Cha. I-FM 4020 ihlanganisa izinhlobo ezahlukene zokwakhiwa kwezitsha, okuhlanganisa izitsha zensimbi eziboshiwe ezinokugqoka kwangaphakathi okwenziwe efektri (njenge-Glass-Fused-to-Steel ne-Epoxy) nezitsha zensimbi ezishiswe ensimini. Kodwa-ke, izitsha eziboshiwe zithandwa kakhulu emkhakheni wezentengiselwano ngenxa yesivinini sazo sokufakwa.
Q: Ingabe isitsha esigunyazwe yi-FM sidinga uhlobo oluthile lokugqoka kwangaphakathi?
A: Izinga le-FM ligxila ikakhulu ekuthembekeni kwezakhiwo kanye ne-hydraulic kunokuba kugxilwe ku-coating uqobo, inqobo nje uma i-coating ivikela ukugqwala okungadala ukuthi ithangi libe buthakathaka noma ivimbele uhlelo lokufafaza. Izinto ezivamile zokugqoka ezihlala isikhathi eside ngaphakathi kwamathangi e-FM zihlanganisa i-Glass-Fused-to-Steel (GFS) kanye ne-epoxies ezikhethekile ze-thermoset.
