Machubhu esimbi asina musono uye akasungirirwa anoita basa rakakosha sezvinhu zvakakosha muindasitiri yemazuva ano.
Magadzirirwo emachubhu aya anonyanya kutsanangurwa nedhayamita rekunze (OD), ukobvu hwemadziro (WT) nehurefu (L), nepo kuverenga huremu hwechubhu yesimbi kunoenderana nematanho aya pamwe nehuremu (ρ) hwezvinhu. Pakuronga mapurojekiti, kudzora mitengo uye logistics, kuverenga kwakarurama kwehuremu hwechubhu yesimbi kwakakosha. Chinyorwa chino chinopa nzira nhatu dzekuverenga huremu hwechubhu yesimbi uye chinoratidza mashandisirwo adzo nemienzaniso inoshanda.
Kuverenga Kwekutanga Kwehuremu hwePaipi
Huremu hwepombi yesimbi hunogona kuverengerwa nekuverenga huwandu hwayo huchiwedzerwa nehuwandu hwesimbi.
Kune mapaipi esimbi akatenderera (kusanganisira asina musono uyemapaipi esimbi akasungirirwa), huremu hunoverengerwa seizvi:
Huremu(kg)=×(OD)2-(OD-2×WT)2)×L×ρ
ODdhayamita yekunze yepombi yesimbi iri mumamita (m);
WTukobvu hwemadziro epombi yesimbi mumamita (m);
Lkureba kwepombi yesimbi mumamita (m);
ρhuwandu hwesimbi, kana iri simbi yakajairwa ine kabhoni, inenge 7850kg/m3.
Algorithm yakareruka: mayuniti eumambo
Huremu（lb/ft)=(OD (mu)−WT (mu))×WT (mu)×10.69
apo 10.69 chinhu chinoverengerwa kubva pakuwanda kwesimbi uye kushandurwa kweyuniti kunoshandiswa kushandura zviyero kubva pamainji kuenda pamapaundi pahurefu hwetsoka imwe neimwe.
Muenzaniso Wekuverenga
Tichifunga chikamu chePombi yesimbi yeERWnedhayamita yekunze ye 10 inches uye ukobvu hwemadziro hwe 0.5 inches, verenga huremu pa futi imwe neimwe yehurefu: Huremu (lb/ft) = (10-0.5) x 0.5 x 10.69
Huremu hwepaipi iyi yesimbi pahurefu hwefiti imwe neimwe hunosvika mapaundi 50.7775.
Algorithm iri nyore: zviyero zvemetric
Huremu (kg)=(OD−WT)×WT×L×0.0246615
OD ndiyo dhayamita yekunze yepombi yesimbi, mumamita (mm);
WT ndiyo ukobvu hwemadziro epombi yesimbi mumamita (mm);
L ndiyo kureba kwechubhu mumamita (m);
0.0246615 yakavakirwa pahuwandu hwesimbi (inenge 7850 kg/m³) uye chinhu chinoshandura unit.
Muenzaniso Wekuverenga
Ngatitii tinepombi yesimbi isina musonoine dhayamita yekunze ye114.3 mm, ukobvu hwemadziro hwe6.35 mm, uye kureba kwemamita gumi nemaviri. Verenga huremu hwepombi uchishandisa fomura iri pamusoro apa:
1. Verenga musiyano uripo pakati pedhayamita neukobvu hwemadziro: 114.3 - 6.35 = 107.95. 2.
2. Verenga huremu nekutsiva fomura iyi: 107.95 × 6.35 × 12 × 0.0246615. 3.
3. Mhedzisiro yacho ndeiyi: 202.86
Saka, huremu hwese hwepombi hunosvika 202.86 kg.
Ma coefficients 10.69 na 0.0246615 ari mufomura akavakirwa pahuwandu hwesimbi. Mhando dzakasiyana dzesimbi (semuenzaniso simbi isingatsvi, simbi ye alloy, nezvimwewo) dzinogona kunge dziine huwandu hwakasiyana uye zvinhu zvinofanirwa kugadziriswa zvinoenderana.
Kuverenga uku kunopa fungidziro yehuremu hwemusonouye machubhu esimbi akasungirirwa. Nekuda kwekusiyana kwehuwandu hwezvinhu, kushivirira kwekugadzira, nezvimwe zvinhu, huremu chaihwo hunogona kusiyana.
Huremu chaihwo hunogona kusiyana zvichienderana nekukwanisa kugadzirwa uye huwandu hwezvinhu, saka fomura iyi ifungidziro. Kuti uverenge huremu nemazvo, zvinokurudzirwa kuti utarise data rakapihwa nemugadziri kana kuti utore zviyero chaizvo.
Kuti pave nekuverenga kwemainjiniya kwakarurama kana kuti pave nemitengo yekutengeserana, zvinokurudzirwa kuti pashandiswe ruzivo rwakadzama kana kuti vatengesi vemapaipi esimbi vabatwe kuti vawane ruzivo rwakarurama rwehuremu.
Kuverenga huremu hwemapaipi chikamu chakakosha chekugadzira mainjiniya uye kudzora mitengo, uye kunzwisisa kwakakodzera uye kushandiswa kwekuverenga uku. Nzira iyi yekuverenga inoshanda kumapaipi esimbi asina musono ane ukobvu hwakatetepa hwemadziro. Kana paine machubhu esimbi asina musono emadziro akakora kwazvo, kuverenga kwakaoma kunogona kudiwa.
ma tag: huremu hwepombi, pombi yesimbi, isina musono, yakasungirirwa.
