Taura Tohu GOST, wetewaehere me iku'anga

taura tohu - ko te whakamahi o kiriuhi o tae rerekē, tono tapanga, te whakamahi o ngā tapanga me tūtohu, me te tohu hiko. E whakaatu ana te tohu i te āhuatanga taura me taea ki te tohatoha i te reira i roto i te tahi atu hua rite.

He aha e nga wehewehenga o waea?

Tohu taura kaha ngā o te pukapuka e hūanga te rauemi i nei te anga, mātao, kaiwhakahaere, me te momo o te tiaki. Tohu ki te taura ngaohiko tiketike ngā āhuatanga hoahoa.

e kore te waea parahi i roto i te tuhituhinga tohua e te pukapuka motuhake. Tikanga, te kaiwhakahaere konumohe - ko te reta "A", e tu i te timatanga o te tohu. Na i reira ko te pukapuka e āta te rauemi mātao. Polyethylene mātao - te reta "P", pvc tohua e te pukapuka "B", ka whakaritea rapa te hiri e te pukapuka "P". I muri ko te reta tohu te momo o raunga, ara te pukapuka "A" - konumohe, te reta "C" - mata, te reta "P" - PE ngongo, te reta "B" - he anga o polyvinyl pūhaumāota, anga rapa - te reta "P" . tu reta Tata momo uhi.

Hei tauira, te ingoa "SG" ko te waea parahi, pepa mātao, takotoranga mata, kahore pukupuku tiaki. taura Oil-tonu tohu Kei te reta "M" (pēhanga hau - te reta "G") me te pukapuka hei whakaatu i te pēhanga hinu āhuatanga āhuatanga, me te whai pānga. Hei tauira, "MHC" te taura - ko reira te hinu-ki tonu taura, pēhanga iti, me koture mata, e kua he taupoki tiaki.

Māka o waea kawea me taura i roto i te tau, me pukapuka i runga i nga paerewa kāwanatanga me ngā: GOST 16442-80 ko TU16.71-277-98.

Rerekē hua i ia atu e te kaupapa tae rerekē

E ti'a ia tatou ki te wehewehe i waenganui i a ratou mo te whakamahi tika o ngā taura. Hei hanga i tenei māmā, i reira te mea he taura tae tohu.

Hoki te tāutu o ngā taura whakamahia parauri, pango, whero, kōwhai, karaka, matomato, tae papura. Na puru, ma, hina, emerara, me te māwhero. whakaturia ana tēnei rārangi e paerewa kāwanatanga.

tikanga waea Blue te mo te kaiwhakahaere reo kūpapa ranei.

kia whakamahi rātou i ngā rerekē o ngā tae. e kore e taea te whakamahi tae Green me kōwhai i roto i te tahi atu ngā atu te huinga o kōwhai me te matomato, a kua whakamahia te reira ki te rawea, he kaiwhakahaere kūpapa tiaki.

Ki te te whenua paruru ngā ki kaiwhakahaere kūpapa - tohu rānei te roa katoa o te huinga kōwhai-matomato, me i nga pito o te puru puru marama ranei marama i runga i te roa katoa me i te pito o te huinga o kōwhai me te matomato.

Tauira o te tautuhi o otaota:

1. te tāututanga Tae o conductors, e kua kiriweti pvc pūhui:

- e toru-waea taura: mangu, puru, parauri ranei te huinga o kōwhai me te matomato, mangu, puru;

- taura wha-matua: Ko te huinga o parauri kōwhai me te matomato (kaiwhakahaere whenua tiaki), pango, puru,.

tīari hoki 2. tautuhi Tae mō te toru taura kotahi-matua, peita pango:

- he taura he tapanga puru;

- he taura kotahi ki kahore he tapanga tapanga mangu ranei;

- he taura he tapanga tae parauri.

3. tāutu Tae o mekameka hiranga mahi:

- no te whakahiko he te iahiko mana, he mea mangu;

- no te conductors, he te mana ara iahiko, whakaoho, me te ine o nāianei i te tāupe, he whero;

- no te conductors, he te tangata kē ara iahiko mana me DC inenga he puru;

- no te conductors tiaki o te kore - he huinga o kōwhai me te matomato;

- no te conductors e kua hono ki te kaiwhakahaere kūpapa a kahore e te tikanga ki te whenua - ko reira te puru.

Ko te tūtohu whakamahia ki te tapa

Tags mō te māka taura te whakamahia mō te māka o te mana me te mana waea. E hanga ana ratou o polypropylene.

Ki te reira e huna taura waea putorino ranei i te taiepa, e piri tūtohu māka ki te putanga taura me te kokoru, i roto i puna me ruma parakaingaki ārai me te pouaka komititanga. I roto i te take o ngā tūtohu tapanga taura ararere whakaturia i roto i ia pouaka, ranei coupler, me i te mutunga. I roto i te tikanga ki te tāuta i te taura i roto i ngā wāhi mākū, kua hanga tapanga o kirihou.

Kaunihera

Na, ka rite ki a koutou e taea te kite i te tuhinga, tohu waea me te taura (i te ara, GOST, he te tahi mea e kia matua e whakarongo ki te kiritaki i te hoko) rawa rerekē. A kihai i pai kia ngāwari ki te whakaoti i tenei te tangata toharite. Koia matou hoatu tohutohu mō te mahi ki te taura, me waea ki te huihui ki te tauturu ngaio. e riro te reira i pai ki te i roto i te mahi o te rangatira ka ngā kore anake te mahi e tika ana, engari ano hoki te hoko o te rauemi e tika ana, kia e kore koutou mahi i takirimatia te ake. Ki te whakatau koe ki te whaiaro-te mahi i tetahi mahi e pā ana ki taura me waea, he mea e tika ana ki te hiahia koe waimarie i roto i tenei mea uaua!
