Machubu achitsulo osapindika komanso olumikizidwa amagwira ntchito yofunika kwambiri monga zigawo zazikulu zamakampani amakono.
Mafotokozedwe a machubu awa amatanthauzidwa makamaka ndi m'mimba mwake wakunja (OD), makulidwe a khoma (WT) ndi kutalika (L), pomwe kuwerengera kulemera kwa chubu chachitsulo kumadalira magawo awa kuphatikiza kuchuluka kwa zinthu (ρ). Pakukonzekera polojekiti, kuwongolera ndalama ndi kayendetsedwe ka zinthu, kuwerengera molondola kulemera kwa chitoliro chachitsulo ndikofunikira. Nkhaniyi ikupereka njira zitatu zowerengera kulemera kwa chubu chachitsulo ndipo ikuwonetsa momwe mungagwiritsire ntchito ndi zitsanzo zothandiza.
Kuwerengera Koyambira kwa Kulemera kwa Chitoliro
Kulemera kwa chitoliro chachitsulo kumatha kuyesedwa powerengera kuchuluka kwake kochulukitsidwa ndi kuchuluka kwa chitsulo.
Pa mapaipi achitsulo chozungulira (kuphatikizapo opanda msoko ndimapaipi achitsulo olumikizidwa), kulemera kumawerengedwa motere:
Kulemera(kg)=×(OD2-(OD-2×WT)2)×L×ρ
ODndi m'mimba mwake wakunja kwa chitoliro chachitsulo mu mamita (m);
WTndi makulidwe a khoma la chitoliro chachitsulo mu mamita (m);
Lndi kutalika kwa chitoliro chachitsulo mu mamita (m);
ρndi kuchuluka kwa chitsulo, pa chitsulo cha carbon wamba, ndi pafupifupi 7850kg/m3.
Algorithm yosavuta: mayunitsi achifumu
Kulemera（lb/ft)=(OD (mu)−WT (mu))×WT (mu)×10.69
kumene 10.69 ndi chinthu chowerengedwa kuchokera ku kuchuluka kwa chitsulo ndi kusintha kwa unit komwe kumagwiritsidwa ntchito kusintha miyeso kuchokera mainchesi kupita ku mapaundi pa phazi lililonse la kutalika.
Zitsanzo Zowerengera
Kungoganiza gawo laChitoliro chachitsulo cha ERWndi mainchesi 10 akunja ndi makulidwe a khoma a mainchesi 0.5, werengani kulemera pa phazi lililonse la kutalika: Kulemera (lb/ft) = (10-0.5) x 0.5 x 10.69
Kulemera kwa chitoliro chachitsulo ichi pa phazi limodzi ndi pafupifupi mapaundi 50.7775 kutalika.
Algorithm yosavuta: mayunitsi a metric
Kulemera (kg)=(OD−WT)×WT×L×0.0246615
OD ndi m'mimba mwake wakunja kwa chitoliro chachitsulo, mu mamita (mm);
WT ndi makulidwe a khoma la chitoliro chachitsulo mu mamita (mm);
L ndi kutalika kwa chubu mu mamita (m);
0.0246615 imachokera ku kuchuluka kwa chitsulo (pafupifupi 7850 kg/m³) ndi chinthu chosinthira unit.
Zitsanzo Zowerengera
Tiyerekeze kuti tili ndichitoliro chachitsulo chosasunthikayokhala ndi mainchesi akunja a 114.3 mm, makulidwe a khoma a 6.35 mm, ndi kutalika kwa mamita 12. Werengani kulemera kwa chitoliro pogwiritsa ntchito njira yosavuta yomwe ili pamwambapa:
1. Werengerani kusiyana pakati pa kukula kwa dayamita ndi khoma: 114.3 - 6.35 = 107.95. 2.
2. Werengerani kulemera mwa kusintha fomula iyi: 107.95 × 6.35 × 12 × 0.0246615. 3.
3. Zotsatira zake ndi izi: 202.86
Chifukwa chake, kulemera konse kwa chitolirocho ndi pafupifupi 202.86 kg.
Ma coefficient 10.69 ndi 0.0246615 mu fomula amachokera pa kuchuluka kwapakati kwa chitsulo. Mitundu yosiyanasiyana ya chitsulo (monga chitsulo chosapanga dzimbiri, chitsulo chosakanikirana, ndi zina zotero) ikhoza kukhala ndi makulidwe osiyanasiyana ndipo zinthuzo ziyenera kusinthidwa moyenerera.
Mawerengedwe awa amapereka chiyerekezo cha kulemera kwawopanda msokondi machubu achitsulo olumikizidwa. Chifukwa cha kusiyanasiyana kwa zinthu, kulekerera kwa kupanga, ndi zina, kulemera kwenikweni kumatha kusiyana.
Kulemera kwenikweni kumatha kusiyana kutengera kulekerera kwa kupanga ndi kuchuluka kwa zinthu, kotero njira iyi ndi yowerengera. Kuti muwerenge molondola kulemera, tikukulimbikitsani kuti muwerenge zomwe wopanga wapereka kapena kuti muyesere zenizeni.
Kuti mupeze mawerengedwe olondola a uinjiniya kapena mitengo yamalonda, tikukulimbikitsani kuti mudziwe zambiri kapena kuti ogulitsa mapaipi achitsulo alumikizane ndi omwe akufuna kudziwa kulemera kolondola.
Kuwerengera kulemera kwa mapaipi ndi gawo lofunikira kwambiri pakupanga uinjiniya ndi kuwongolera ndalama, komanso kumvetsetsa bwino ndikugwiritsa ntchito mawerengedwe awa. Njira yowerengera iyi imagwira ntchito pa chitoliro chachitsulo chosasunthika chokhala ndi makulidwe ochepa a khoma. Pankhani ya mapaipi achitsulo chosasunthika a khoma chokhuthala kwambiri, mawerengedwe ovuta kwambiri angafunike kuganiziridwa.
