ITorch yaseDubai iTorch yoMlilo iphose imibhobho yentsimbi yokuKhusela uMlilo

Umlilo weTorch Tower yaseDubai

Ngo-Agasti 4th 2017, Idangatye elikhulu liye lakrazula esinye sezona zakhiwo zikhulu zokuhlala emhlabeni, iTorch Tower eDubai. Amadangatye adubule kwicala le-skyscraper, ethumela inkunkuma edilikayo ukusuka kwi-337m (1,106 ft) isakhiwo. Abantu babekhwaza njengoko bevuka kwilangatye lasebusuku ngaphambi kokuba babaleke. Ngethamsanqa, iDubai Civil Defense ikhuphe ngempumelelo itotshi kwaye ilawule umlilo, akukho nzakala kodwa ilahleko yezoqoqosho ngokuthe ngqo yamashumi ezigidi zeedola. I-Dubai Civil Defense ithe ibhodi yokugquma eludongeni enokutsha yesakhiwo ukwenza umlilo weTorch usasazeke ngokukhawuleza, ukhuseleko lwezixhobo zokwakha lufanelekile ukuphononongwa.

UkuFunda okwandisiweyo
Xa kuthelekiswa nombhobho wePVC, kutheni ukhetha inkqubo yokukhupha umbhobho wentsimbi ye-DS? – Ukhuseleko lomlilo

I-Dinsen ibandakanyeka ikakhulu kwi-EN877 DS yophawu lwe-epoxy resin iphosa imibhobho yentsimbi yokuhambisa amanzi kunye nezincedisi ezisetyenziswa kuninzi lweendlela zokuhambisa amanzi kwisakhiwo, ugutyulo kunye neenkqubo zokuphefumla. Xa kuthelekiswa nemibhobho yeplastiki kuzisa ingxolo kunye neengxaki zokhuseleko lomlilo, imibhobho yentsimbi ephosiweyo ineempawu ezibalaseleyo ezicacileyo: amandla aphezulu, ukuxhathisa ukukrazula, ukubola kunye neempembelelo, ukuvutha umlilo kunye ne-non-toxic, ukuhlangabezana nokhuseleko lomlilo kunye neemfuno zokhuseleko lokusingqongileyo, akukho ngxolo, akukho deformation, ubomi obude, ukufakwa lula kunye nokugcinwa kweenzuzo.

Nantsi ingqwalasela ekuxhathiseni umlilo we-DS cast iron pipe. Imibhobho yentsimbi ye-DS kunye nezixhobo zibandakanya intsimbi engwevu kunye negraphite ye-lamellar, iimvavanyo kunye neenkcukacha zobugcisa zichazwe ukuba zihambelane ne-EN877. I-Annex F ye-EN877 ithi iimveliso ze-Cast iron ngokuhambelana nalo mgangatho waseYurophu azinakutsha kwaye azinakutsha. Xa bevezwe emlilweni baya kugcina iimpawu zabo zokusebenza kunye nokuthembeka iiyure ezininzi, oko kukuthi iindonga zabo ziya kuhlala zingenako ukuvutha amadangatye kunye neegesi kwaye akuyi kubakho kuphuka, ukuwa okanye ukuguqulwa okubalulekileyo. Ukunyaniseka kokudibanisa ngeendonga kunye neesilingi zigcinwa.

I-DS cast iron ayinakutsha, ayiwondli umlilo, kwaye ayikhuphi iigesi okanye imisi enoxanduva lokulibazisa abacimi-mlilo okanye ukonakalisa ezinye izixhobo. Kwimeko yomlilo ibonisa iingenelo ezimbini ezicacileyo:

1 Ukumelana nomlilo - ukuthintela ukusasazeka komlilo
Iinkqubo zokuhambisa amanzi ezidlula kwizakhiwo ezenzelwe ukumelana nomlilo, akufanele zibonelele ngokuphulwa okuvulekileyo. Ngexesha elithile, elichazwe kwimimiselo esebenzayo, akufanele bavumele ukuhamba komlilo, ukutshaya, ukushisa okanye ukutsha kwemveliso ukusuka kwelinye igumbi ukuya kwelinye. Ngelixa iiplastiki, umgaqo wokumisa umlilo ubandakanya 'ukufaka umngxuma', izinto zeplastiki ezinobuzaza kakhulu kubushushu aziyi kumelana nomlilo, aziyi kuhlala zisendaweni, nakwimeko yomlilo ovaliweyo.

2 Ukuthintela umonakalo womsi onetyhefu
Umbhobho wePlastiki xa utshisa uya kuvelisa inani elikhulu lemiphunga enobuthi, kulula ukusasazeka. Ngelixa umbhobho wokukhupha amanzi entsimbi ungatsha, ukuze ungakhuphi umsi onetyhefu. Kwakhona kuya kubakho umsi omncinci ukuba ufakwe kunye nee-couplings ezigaskets zerabha zigqunywe ngokupheleleyo ngeekhola zensimbi ezingenasici (umzekelo, i-DS Rapid coupling okanye i-CH / CV / CE coupling), inkqubo yombhobho ihlala ivaliwe xa kunomlilo. Nawuphi na umsi oveliswa ziziphumo zobushushu kwindawo engaphakathi uhlala ukwimibhobho kwaye emva koko uyakhutshwa ngeembobo zokuphefumla phezu kophahla.

Ulwazi oluthe vetshe, wamkelekile ukuba uqhagamshelane nathi.
