Mo te pereti kowiri tira: he tino onge tatou inaianei, engari na te nui o te rahi, te utu nui, te uaua ki te tiki, kaore i te ngawari ki te kawe me etahi atu take, ka kitea te maakete e te pereti kowiri tira papatahi. .

Kua wehea te pereti kowiri tira ki nga waahanga e rua:

whakarōpūtanga whanui pereti kowiri tira

1, matao takaia he kowiri tira pereti coil pereti me te coil pereti flat plate.
A, kua wehea te pereti kowiri tira ki te 1 m, 1.219 m te mata o te pereti, te 1.5 te mata o te pereti.
B. Ko te rahi noa o te pereti kowiri tira he 1 m *2 m, 1.219 m *2.438 m

2, ka wehea te pereti kowiri tira wera ki te pereti porohita, pereti papatahi me te pereti wera wera.
A, kowiri tira pereti pōkai whakamahia nuitia mata he 1.5 mita, 1.25 mita
B, pereti paraharaha kowiri tira rahi noa 1.5 * 6 m, 1.8 * 6 m, 1.25 * 6 m.

Ko te rahinga o nga rawa pereti kowiri tira e whakamahia ana

Te tātai tātai ariā o te pereti kowiri tira:

Taumaha ariā (kg) = Roa (m) * Whānui (m) * Matotoru (mm) * Tino Tau (kiato)

Utu pereti papatahi: utu coil * te tino matotoru/te matotoru ariā + utu utu

Tauira o te hurihanga utu nui pereti:

Ko te tino matotoru o te matotoru paerewa o te 2 mm pereti kowiri tira he 1.8 mm, na ko te taumaha o te 2 toni o te pereti kowiri tira he 1.8 tone.Mena ko te utu whakatikatika he 11400 yuan/ton, ko te utu pauna mo te (2/1.80) *11400=12650 yuan/ton, (te taumaha kino o te manawanui (1.80-2) /2*100%=10%, 11400/ (1 -9%) =12650 yuan/ton) kei te taumaha te utu rōrahi whānui, he tiketike te utu;Ka whakatikahia te utu o te Poari, i te pauna pauna, he iti iho te utu i te utu pauna.(Ka whakamahia e nga umanga whanui tenei huarahi whakataunga, na te mea ka 5% te rereketanga o te pereti kowiri tira whanui, a ko etahi ka tae ki te 30%, na reira ka tino nui te utu o te taumaha).

Te rahi o te pereti kowiri tira matao noa

Te rahi o te pereti kowiri tira wera hurihia te rahi

Kowiri tira momo tatauranga

1, utu = tino matotoru ÷ matotoru * i roto i te utu + utanga + utu tukatuka

2, huri te utu pereti porowhita ki te utu pereti = utu rōrahi * te matotoru mārō/te matotoru + utu papatahi 100

3, te utu pereti papatahi ka huri ki te utu pereti coil = utu poari * te matotoru whakahaere / te matotoru totoka - utu utu 100

4. Te roa o te reel = te taumaha reel net /7.93/ te whanui reel/te tino matotoru

5, te algorithm o te utu me te taake = te taumaha katoa o nga taonga /1.04(1.04 e tohu ana i te 4 ira -1.07 te tikanga e 7 nga tohu) tauira :10000 tone o taonga /1.04=9615.3846 tone * tone utu = tauira hua :1 ton o taonga =15800 tons /1.04=15192.3077 utu kore taake

6. Ka hoatu te taimaha rōrahi me te utu, kimihia te tapeke taumaha o te rōrahi = rōrahi taumaha * utu
