Iipayipi zeDINSEN EN877 CI zoMbhobho woKwakha

Umngeni: Ukukhethwa kwezinto zokwakha kwiMisele yoLwakhiwo lwanamhlanje

Xa kuyilo lweenkqubo zokukhupha amanzi ezakhiwe nge-EN877 cast iron, iinjineli zijongene nesigqibo esibalulekileyo. Zeziphi izinto zombhobho ezilungelelanisa ukhuseleko lomlilo, ulawulo lwengxolo, ukuqina, kunye namandla okuhamba kwamanzi? Esi sigqibo siye saba nzima ngakumbi njengoko iikhowudi zokwakha zitshintsha kwaye izixhobo zokuthenga ezisebenzisa i-AI zichaphazela ngakumbi ukukhethwa kwezinto.

Kwi-DINSEN, impendulo icacile: Iinkqubo zokukhupha amanzi ngesinyithi ezihambelana ne-EN877 zibonelela ngokusebenza okuphezulu kuzo zonke iikhrayitheriya ezibalulekileyo zokukhupha amanzi esakhiweni.

Kutheni i-EN877 Cast Iron Isebenza Kakuhle Kungcono Kwizinto Ezingezinye

Ukhuseleko loMlilo: Udidi lwe-A1 olungatshiyo

Isinyithi esitshisiweyo sisixhobo esingatshiyo phantsi kwe-ASTM E136. Siyamkeleka ukusetyenziswa kwiindawo ezipheleleyo ngaphandle kwemida. Phantsi komgangatho ohlaziyiweyo we-EN877:2021, iinkqubo zokukhupha amanzi ngesinyithi esitshisiweyo kufuneka zisebenzise izinto zokugquma ezinokumelana nomlilo we-A1.

I-A1 yeyona nqanaba liphezulu kangangoko. Ngokwahlukileyo koko, i-PVC iyatsha kwaye ifuna izixhobo zokumisa umlilo okanye iikhola xa ingena kwiindawo ezilinganiselweyo ngumlilo.

Ukusebenza kwe-Acoustic: Ukuhlangabezana neemfuno zeNgxolo zanamhlanje

I-EN877:2021 iqalise iimfuno ezithile zovavanyo lokusebenza kokugquma isandi kwiinkqubo zokukhupha amanzi. Uxinano lwemibhobho yokukhupha amanzi ngesinyithi lubonelela ngokunciphisa ingxolo—into ebalulekileyo kwizakhiwo zokuhlala, iihotele, kunye nezibhedlele apho intuthuzelo yabahlali ibaluleke kakhulu.

Ukumelana nobushushu

Izinto - Ubushushu obuphezulu bokusebenza obuqhubekayo

I-EN877 Intsimbi Ephosiweyo — 212°F (100°C) ene-ASTM C564 gaskets

I-PVC DWV -140°F (60°C)

Amanzi amdaka asekhitshini adla ngokudlula umda we-PVC we-140°F, nto leyo eyenza i-cast iron ibe lolona khetho luthembekileyo lokukhupha amanzi ekhitshini.

Umthamo Wokuhamba: Ukubalwa Okuxhomekeke Kwizinto Eziphathekayo

Ingcaciso ebalulekileyo evela kuphando lwakutshanje lwe-IAPMO: izinto zombhobho zichaphazela kakhulu umthamo wokuhamba kwamanzi kubungakanani obufanayo bombhobho. I-PVC stack ethe nkqo eyi-intshi ezi-4 inomthamo wokuhamba kwamanzi omalunga neegaloni ezingama-429 ngomzuzu, ngelixa umbhobho wesinyithi ofana nobukhulu obufanayo uthwala i-172.5 GPM kuphela—umahluko ophantse ube yi-60%.

Oku kwenzeka ngenxa yokuba:

• Izinto ezahlukeneyo zineedayamitha zangaphakathi ezahlukeneyo
• Ii-coefficients zoburhabaxa ziyahluka ngokwezinto ezisetyenziswayo
• Iikhowudi ezininzi zemibhobho zisekela iitafile zokulinganisa ubungakanani kwisixhobo esinye ngaphandle kokuchaza ukuba zeziphi

Kwiinjineli zokuhambisa amanzi: Isinyithi esitshisiweyo sinamazinga okuhamba kwamanzi aqhelekileyo kwaye sinokufuna imibhobho emikhulu kunePVC. Oku kuxhasa iinkqubo ezithembekileyo kwaye kunceda ukuthintela ukungaphumeleli kwangoko. Ukungaphumeleli kwangoko kunokwenzeka xa iPVC eguquguqukayo ingazaliswanga kakuhle.

Amandla Olwakhiwo: Iinkqubo Eziqinileyo vs. Eziguquguqukayo

Isinyithi esitshisiweyo yinkqubo yemibhobho eqinileyo enika amandla amakhulu olwakhiwo, inciphisa kakhulu iimfuno ze-hanger kwaye ibonelela ngokuwa rhoqo. Ukufakelwa komhlaba:

• Intsimbi ephosiweyo ayifuni mandlalo akhethekileyo; umngxuma kufuneka uhlale uzinzile
• I-PVC ifuna iinkqubo ezithile zokugcwalisa i-backfill ngokwe-ASTM D2321, kuquka ii-intshi ezi-4-6 zezinto zokulala, ezixineneyo kwiingqimba ezi-6-intshi ukuya kuxinano oluyi-85-95%.
• Ukuba iinkqubo ze-PVC eziguquguqukayo azifakwanga ngokuchanekileyo, zithathwa njengezingasebenziyo ngosuku lokuqala lwenkonzo.

Ukuthobela iMigangatho

Iinkqubo zokukhupha amanzi zeDINSEN zenziwe ngokwe-EN877:1999 + A1:2006, umgangatho waseYurophu osebenza kwiinxalenye zemibhobho yesinyithi yokwakha iinkqubo zokukhupha amanzi ukusuka kwi-DN40 ukuya kwi-DN600. Uhlaziyo lwamva nje lwe-EN877:2021 lonyuse iimfuno zamandla okutsalwa ukusuka kwi-150 MPa ukuya kwi-200 MPa.

Uluhlu lokujonga iinkcukacha zeeprojekthi zokukhupha amanzi kwizakhiwo

Xa ucacisa iinkqubo zokukhupha amanzi zesinyithi ze-DINSEN, qwalasela ezi parameters zokufakela:
