Jiri juru kɔrɔtacogo kunbabaw ye jumɛnw ye?

I n’a fɔ kɔrɔta masinw yɔrɔ koloma, nɛgɛ juru kɔrɔtacogo bɛ nɔ bila k’a ɲɛsin fɛnw kɔrɔta baara lakanani n’u ka baarakɛcogo ɲuman ma.

O jogo jɔnjɔnw ye ninnu ye:

I. Masina jogo ɲumanw Nɛgɛ juruw kɔrɔtacogo fɔlɔ ye u ka masinko ɲumanya ye, o min ye fɛnba ye u ka se ka doni girinmanw ta.

1.1 Tensile fanga ka bon

Kɔrɔta juruw bɛ dilan ni nɛgɛ ye min ka bon kosɛbɛ (a ka c’a la, nɛgɛ min fanga ka bon). U ka sɔgɔli fanga tɔgɔlama ka bon kosɛbɛ (a ka c’a la 1770 N/mm2 walima 1960 N/mm2), o bɛ kari fanga dɔgɔyalenba sabati ni u cɛmancɛ ka dɔgɔn kosɛbɛ, ka doni girinmanw wajibiyalenw dafa.

1.2 Sɛgɛn baarakɛcogo ɲuman

Jiri juruw kɔrɔtalen bɛ tɛmɛ siɲɛ caman dununw ni wuluwuluw kan baara kɛtuma na, ka cyclique bending ni tensile stresses muɲu.

(2) Sɛgɛn min bɛ sɔgɔsɔgɔ: Filɛriw ka kan ka se ka kɔnɔna mikoro-kuruw jɛnsɛnni kɛlɛ, minnu bɛ sɔrɔ doni jiginni fɛ tuma bɛɛ.

1.3 Gɛlɛya ni lakanaba:

Jiri juru minnu bɛ se ka kɔrɔta, olu ka gɛlɛya bɛrɛ bɛ u la, o kɔrɔ ye k’u bɛ plastiki bɔgɔlan dɔw jira ani nɛgɛ kari taamasiɲɛw sani u ka se u ka kari doni ma, sanni u ka kari yɔrɔnin kelen, min bɛ kɛ balawu ye. O bɛ lakana sira nafamaw di ani lasɔmini waati.

II. Jagokɛcogo ni jɔcogo suguya caman: Jiri juruw kɔrɔtacogo baarakɛcogo tɛ se ka faranfasi n’u jɔcogo gɛlɛn ni tigitigi ye.

2.1 Jateminɛ kɛcogo

Kɔrɔta juruw bɛ kɛ yɔrɔ saba ye:

Filɛriw: Aw bɛ fanga fɔlɔ di.

Fɛnɲɛnɛmaw: U bɛ Kɛ ni nɛgɛ caman ye minnu bɛ firifiri ka Kɛɲɛ ni cogoya kɛrɛnkɛrɛnnen dɔ ye, u ye doni-ta-minɛn jɔnjɔn ye.

Core: A bɛ sɔrɔ nɛgɛ juru cɛmancɛ la, a bɛ juruw dɛmɛ, ka juru tigɛcogo sabati, ka tulu mara. Kɔrɔ suguya caman bɛ yen, i n’a fɔ fibre core (FC), wire rope core (IWRC), walima wire strand core (WSC), ni IWRC bɛ fanga ni degun fanga caman di, o b’a to a ye sugandili ɲuman ye kurun gɛlɛnw na.

2.2 Twisting fɛɛrɛ

Twisting fɛɛrɛ bɛ nɛgɛ juru baarakɛcogo sinsincogo dantigɛ:

(1) Lang Lay: Filɛriw ni juruw bɛ firifiri sira kelen fɛ. A bɛ se ka fɛn caman sɛgɛsɛgɛ, ka sɛgɛn kunbɛn, ani ka baara kɛ waati jan, nka a bɛ baara kɛcogo ɲuman de wajibiya ka ɲɛsin jiginni kɛlɛli ma.

(2) Layi gansan: Filɛriw ni juruw bɛ firifiri ka taa fan wɛrɛw fɛ. A bɛ jɔcogo sabatili caman di wa a tɛ lajɔ kosɛbɛ.

(3) Jagokɛyɔrɔ kɛrɛnkɛrɛnnen: Ni nɛgɛ juru minnu tɛ wuli, olu bɛ kɛ ni jiribolo caman ye (misali la, 35x7). Kɔnɔna ni kɛnɛma layiniw bɛ ni tigɛli siraw ye minnu tɛ kelen ye walasa ka jiginni girinya kɛlɛ. O bɛnnen don kɛrɛnkɛrɛnnenya la juru kelen kɔrɔtacogo la, wa a nafa ka bon kosɛbɛ walasa ka lakana sabati baarakɛyɔrɔw la minnu bɛ sanfɛ.

III. Muɲuli ni a lakanani baarakɛcogo

Walasa ka ladamu izini ni kɛnɛma sigida gɛlɛnw na, nɛgɛ juruw kɔrɔtalen ka kan ka kɛ ni muɲuli ye min bɛ mɛn.

3.1 Abrasion (sɔgɔsɔgɔninjɛ) kunbɛncogo

Ni nɛgɛ juru tɛmɛna ɲɛminɛlanw fɛ, jirisunba blokiw fɛ ani dununw fɛ, a bɛna a maga nɛgɛw la. Kɛnɛma nɛgɛw ka kan ka kɛ ni gɛlɛya ni sɔgɔli ye ka ɲɛ walasa ka se ka doni tacogo ɲuman dɔgɔyali kunbɛn min bɛ sɔrɔ sanfɛla sɛgɛn fɛ.

3.2 Nɔgɔw lakanani & tulumafɛnw

Nɔgɔli lakanani: A ka c’a la, nɛgɛbere bɛ galvanize walasa ka saraka anode lakanani jɔnjɔn di fiɲɛ ni ji sɔgɔli ma.

Kɔnɔna tulu: Kɔrɔta juru minnu ka ɲi kosɛbɛ, olu bɛ tulu doncogo ɲuman don u la u dilanni senfɛ. Nin tulu in tɛ dan dɔrɔn ka dɔ bɔ nɛgɛw ni jiriw cɛ sɔgɔsɔgɔli la, ka sɛgɛn nɔgɔya, nka a bɛ kɛ fana i n’a fɔ balilanba ye kɔnɔna sɔgɔli ma. Gɛrɛsi bɔnɛ ye sababuba ye min bɛ kɛ sababu ye ka nɛgɛ juru tiɲɛ.

Kuma surun: Jiri juruw kɔrɔtacogo kunbabaw bɛ se ka lajɛ nin cogo la:
