Iityhubhu zentsimbi ezingenamthungo nezihlanganisiweyo zidlala indima ebalulekileyo njengezinto ezisisiseko kushishino lwanamhlanje.
Iinkcukacha zezi tyhubhu zichazwa ikakhulu bububanzi bangaphandle (OD), ubukhulu bodonga (WT) kunye nobude (L), ngelixa ukubala ubunzima betyhubhu yentsimbi kusekelwe kwezi parameters zobukhulu kunye noxinano (ρ) lwezinto. Kucwangciso lweprojekthi, ulawulo lweendleko kunye nothutho, ukubala ngokuchanekileyo ubunzima bombhobho wentsimbi kubalulekile. Eli nqaku libonisa iindlela ezintathu zokubala ubunzima betyhubhu yentsimbi kwaye libonisa indlela yokuzisebenzisa ngemizekelo esebenzayo.
Ukubalwa Okusisiseko Kobunzima Bepayipi
Ubunzima bombhobho wentsimbi bunokuqikelelwa ngokubala umthamo wawo uphindaphindwe ngobuninzi bentsimbi.
Kwimibhobho yentsimbi engqukuva (kuquka i-seamless kunyeimibhobho yentsimbi edityanisiweyo), ubunzima bubalwa ngolu hlobo lulandelayo:
Ubunzima(kg)=×(OD)2-(OD-2×WT)2)×L×ρ
ODbububanzi bangaphandle bombhobho wentsimbi ngeemitha (m);
WTbubungakanani bodonga lombhobho wentsimbi ngeemitha (m);
Lbubude bombhobho wentsimbi ngeemitha (m);
ρbubuninzi bentsimbi, kwintsimbi eqhelekileyo yekhabhoni, imalunga ne-7850kg/m3.
I-algorithm elula: iiyunithi zobukhosi
Ubunzima（lb/ft)=(OD (in)−WT (in))×WT (in)×10.69
apho i-10.69 yi-factor ebalwa ukusuka kubuninzi bentsimbi kunye nokuguqulwa kweyunithi esetyenziselwa ukuguqula ubukhulu ukusuka kwi-intshi ukuya kwiipawundi ngenyawo nganye yobude.
Imizekelo Yokubala
Ukucinga ukuba icandelo leUmbhobho wentsimbi we-ERWngobubanzi bangaphandle obuziisentimitha ezili-10 kunye nobukhulu bodonga obuziisentimitha ezili-0.5, bala ubunzima ngenyawo nganye yobude: Ubunzima (lb/ft) = (10-0.5) x 0.5 x 10.69
Ubunzima ngenyawo nganye ubude bale mbhobho yentsimbi bumalunga neekhilogram ezingama-50.7775.
I-algorithm elula: iiyunithi ze-metric
Ubunzima (kg)=(OD−WT)×WT×L×0.0246615
I-OD bububanzi bangaphandle bombhobho wentsimbi, ngeemitha (mm);
I-WT bubukhulu bodonga lombhobho wentsimbi ngeemitha (mm);
U-L bubude betyhubhu ngeemitha (m);
I-0.0246615 isekelwe kubuninzi bentsimbi (malunga ne-7850 kg/m³) kunye ne-unit conversion factor.
Imizekelo Yokubala
Masithi sinayoumbhobho wentsimbi ongenamthungoenobubanzi bangaphandle obuyi-114.3 mm, ubukhulu bodonga obuyi-6.35 mm, kunye nobude obuyi-12 m. Bala ubunzima bombhobho usebenzisa le fomyula ilula ingasentla:
1. Bala umahluko phakathi kobubanzi kunye nobukhulu bodonga: 114.3 - 6.35 = 107.95. 2.
2. Bala ubunzima ngokutshintsha le fomula: 107.95 × 6.35 × 12 × 0.0246615. 3.
3. Isiphumo sesi: 202.86
Ngoko ke, ubunzima obupheleleyo bombhobho bumalunga ne-202.86 kg.
Ii-coefficients eziyi-10.69 kunye ne-0.0246615 kwifomula zisekelwe kubuninzi bentsimbi. Iintlobo ezahlukeneyo zentsimbi (umz. intsimbi engatyiwayo, intsimbi ye-alloy, njl.njl.) zinokuba nobunzima obahlukeneyo kwaye izinto kufuneka zilungiswe ngokufanelekileyo.
Ezi zibalo zibonelela ngoqikelelo lobunzimaingenamthungokunye neetyhubhu zentsimbi ezidityanisiweyo. Ngenxa yobuninzi bezinto ezisetyenziswayo, ukunyamezelana kokwenziwa kwezinto, kunye nezinye izinto, ubunzima bokwenyani bunokwahluka.
Ubunzima bokwenyani bunokwahluka ngokuxhomekeke kukunyamezelana kokwenziwa kunye nobuninzi bezinto, ngoko ke le fomula luqikelelo. Ukuze ufumane ubalo oluchanekileyo lobunzima, kucetyiswa ukuba ubhekisele kwidatha enikwe ngumenzi okanye ukuba uthathe imilinganiselo yokwenyani.
Ukuze ufumane izibalo zobunjineli ezichanekileyo okanye iikowuteshini zorhwebo, kucetyiswa ukuba kusetyenziswe idatha eneenkcukacha ezingaphezulu okanye kuqhagamshelwe abathengisi beepayipi zentsimbi ukuze kufunyanwe ulwazi oluchanekileyo ngobunzima.
Ukubala ubunzima bepayipi yinxalenye ebalulekileyo yoyilo lobunjineli kunye nolawulo lweendleko, kunye nokuqonda okufanelekileyo kunye nokusetyenziswa kwezi zibalo. Le ndlela yokubala isebenza kumbhobho wentsimbi engenamthungo onobukhulu obuncinci bodonga. Kwimeko yetyhubhu yentsimbi engenamthungo eludongeni ebanzi kakhulu, kubalwa okuntsonkothileyo kunokufuneka kuqwalaselwe.
iithegi: ubunzima bombhobho, umbhobho wentsimbi, ongenamthungo, odibeneyo.
