Iityhubhu zentsimbi ezingenamthungo nezidityanisiweyo zidlala indima ebalulekileyo njengamacandelo asisiseko kushishino lwanamhlanje.
Inkcazo yale mibhobho ichazwa ikakhulu yi-diameter yangaphandle (OD), ubukhulu bodonga (WT) kunye nobude (L), ngelixa kubalwa ubunzima betyhubhu yentsimbi isekelwe kwezi parameters ezinobungakanani kunye noxinzelelo (ρ) lwemathiriyeli. .Ukucwangciswa kweprojekthi, ukulawulwa kweendleko kunye ne-logistics, ukubalwa ngokuchanekileyo kobunzima bombhobho wensimbi kubalulekile.Eli nqaku libonisa iindlela ezintathu zokubala ubunzima beetyhubhu zetsimbi kwaye libonisa indlela yokuzisebenzisa ngemizekelo ebonakalayo.
UBalo oluSisiseko lobunzima boMbhobho
Ubunzima bombhobho wensimbi bunokuqikelelwa ngokubala umthamo wayo wanda ngobuninzi bentsimbi.
Kwimibhobho yentsimbi ejikelezayo (kubandakanywa i-seamless kunyeimibhobho yentsimbi edityanisiweyo), ubunzima bubalwa ngolu hlobo lulandelayo:
Ubunzima(kg)=×(OD2-(OD-2×WT)2)×L×ρ
ODyi-diameter yangaphandle yombhobho wensimbi kwiimitha (m);
WTbubunzima bodonga lombhobho wentsimbi kwiimitha (m);
Lubude bombhobho wentsimbi kwiimitha (m);
ρUbuninzi bentsimbi, kwintsimbi yekhabhoni eqhelekileyo, malunga ne-7850kg/m3.
I-algorithm eyenziwe lula: iiyunithi zobukhosi
Ubunzima（lb/ft)=(OD (in)−WT (in))×WT (in)×10.69
apho i-10.69 yinto ebalwa ukusuka kubuninzi bentsimbi kunye nokuguqulwa kweyunithi esetyenziselwa ukuguqula imilinganiselo ukusuka kwi-intshi ukuya kwiipounds ngeenyawo ubude.
Umzekelo wokubala
Ukuthatha icandelo leERW umbhobho wentsimbikunye nobubanzi obungaphandle bee-intshi ezili-10 kunye nobukhulu bodonga lwe-intshi ye-0.5, bala ubunzima ngeenyawo zobude: Ubunzima (lb / ft) = (10-0.5) x 0.5 x 10.69
Ubunzima ngeenyawo zobude balo mbhobho wentsimbi bumalunga ne-50.7775 pounds.
I-algorithm eyenziwe lula: iiyunithi zemetric
Ubunzima (kg)=(OD−WT)×WT×L×0.0246615
I-OD yi-diameter yangaphandle yombhobho wensimbi, kwiimitha (mm);
I-WT ubukhulu bodonga lombhobho wensimbi kwiimitha (mm);
L bubude betyhubhu kwiimitha (m);
I-0.0246615 isekelwe kubuninzi bentsimbi (malunga ne-7850 kg / m³) kunye neyunithi yokuguqulwa kweyunithi.
Umzekelo wokubala
Masithi sine aumbhobho wentsimbi ongenamthungokunye nobubanzi obungaphandle be-114.3 mm, ubukhulu bodonga lwe-6.35 mm, kunye nobude be-12 m.Bala ubunzima bombhobho usebenzisa ifomula elula engentla:
1. Bala umahluko phakathi kobubanzi kunye nobukhulu bodonga: 114.3 - 6.35 = 107.95.2.
2. Bala ubunzima ngokufaka ifomyula: 107.95 × 6.35 × 12 × 0.0246615.3.
3. Isiphumo sithi: 202.86
Ngoko ke, ubunzima obupheleleyo bombhobho bumalunga ne-202.86 kg.
I-coefficients 10.69 kunye ne-0.0246615 kwifomyula isekelwe kubuninzi obuqhelekileyo bentsimbi.Iindidi ezahlukeneyo zentsimbi (umz. insimbi engenasici, intsimbi yealloyi, njl.njl.) zinokuba noxinaniso olwahlukileyo kwaye izinto kufuneka zihlengahlengiswe ngokufanelekileyo.
Ezi zibalo zibonelela ngoqikelelo lobunzima beengenamthungokunye netyhubhu yentsimbi edityanisiweyo.Ngenxa yokuxinana kwezinto eziphathekayo, ukunyamezelwa kwemveliso, kunye nezinye izinto, ubunzima bokwenene bunokwahluka.
Obona bunzima bunokwahluka ngokuxhomekeke kwimveliso kunye nokuxinana kwempahla, ke le fomula luqikelelo.Ukubalwa ngokuchanekileyo kobunzima, kucetyiswa ukuba ubhekiselele kwidatha enikezelwe ngumenzi okanye ukuba uthathe imilinganiselo yangempela.
Ukubalwa kobunjineli obuchanekileyo okanye iikowuteshini zentengiso, kucetyiswa ukuba kusetyenziswe idatha ethe kratya okanye ukuba abaxhasi bemibhobho yentsimbi baqhagamshelane ngolwazi oluchanekileyo lobunzima.
Ukubalwa kobunzima bombhobho yinxalenye esisiseko yoyilo lobunjineli kunye nolawulo lweendleko, kunye nokuqonda okufanelekileyo kunye nokusetyenziswa kwezi zibalo Le ndlela yokubala isetyenziswa kumbhobho wentsimbi engenamthungo enobunzima obuncinane bodonga.Kwimeko yodonga olungqingqwa lwetyhubhu yentsimbi engenamthungo, izibalo ezintsonkothileyo zinokufuna ukuqwalaselwa.
