Kuwaha ahi: te momo āhuatanga me ngā āhuatanga o te pūrere

Hoki te ahi pehanga titau te pūnaha katoa arā o te tukuwai, ngongo, vaolo me ētahi atu momo o huānga. Ēnei whakaaro tukua ki te homai tika wai ki te mata o te pātīmata. e kore te mea oti, kahore he tapo'i-kounga tiketike ki te i te piha, ko te ahi e kore pūnaha tupohe i te ahi. Fakakaukau ki he me'a momo reira e, o ratou rerekētanga me te painga o te whakamahi i.

mahi normative

I roto i te take katoa e pā ana ki ngā pūnaha tiaki ahi, e ture wahi ki tohutoro ki te tuhinga e whai ake nei:

• NPB 154-2000. heheu tenei waeture nga kōrero katoa e pā ana ki te tikanga o te ahi, mapuni, hydrants ahi. Reira regulates hoki te hangarau wahi: ngā whakaritenga me ngā tikanga o te taputapu whakamātautau haumaru.
• GOST P 53278-2009. hanga tuhinga mua tohutoro ki te Paerewa rite te tuhinga taketake, e whakarato ana te whakamārama tika atu o etahi uara ture.
• Ture Federal №123. regulates tenei ture te āhuatanga ture i roto i te take o te ahi, me te mehua ki te ārai i te reira.

Ēnei ture faatere i ngā wāhi katoa, i hanga o vaolo mua ki te whakamahi me te whakamātautau.

He aha te mea te reira?

kuwaha Fire (aka piha) he wāhanga o te warou. Eke i runga i te roto o te pūnaha supply wai mo te ahi tupohe i inu hau ranei te pāmahana ki te 50 ° C. ka kia kotahi mutunga o tenei hua i roto i te puka o te ringaringa, me te tuarua - tsapkovy (tane) mo screwing te matenga hononga honotanga. Na roto i te hoahoa, he kore rerekē i ritenga tikanga vaolo ahi. Ko te rerekētanga - anake i roto i te whānui me te rauemi. I roto i to ratou hoahoa, to ratou he handwheel bushing tarapēke repe tinana matenga, tokotoko whiria, wehe takirere ki te gasket.

momo

taea te kitea te maha o ngā momo rite ki ngā paearu:

• E ai ki te momo o te tāutanga - teihana, taiepa.
• Na roto i te kōrero ki te hanganga takere waho - koki (90 ° 125 ° ranei), me kōrero, i roto i-rere.
• Na roto i te mahi - tutakina atu, tutakina-atu, me te ture motuhake.
• Ko te rauemi - rino, te parahi.
• Ka rite ki te diameter ā-- 50 mm ranei 65 mm.
• E ai ki te momo o te hononga - hononga / mamau, mamau / hoe. Hoe i te piha ahi ngongo taea hononga ki te ngongo (ngongo ferrule ahi).

e kore e te momo o whakarōpūtanga pā te kounga taketake o te tika - tika.

Whakaritenga ki te piha

He he maha o ngā whakaritenga ki te mapuni ahi:

• taati hua me pūhui;
• NW - i 40 ki te 65 mm;
• mahi pēhanga ka te supply wai - e kore e iti iho i te 1 MPa;
• Ko te pēhanga mahi i raro i te piha;
• kore me te pāmahana whakahaere nui 50 ° C;
• maha o takaí i mua i te whakatuwheratanga - i te 4 ki te 6, i runga i te irava iti rānei;
• hurihanga tōhito - tika;
• crimping whakahauanga mō te 12 haora i mua i te hoko.

Katoa o enei whakaritenga hanga hohoro taea reira ki te ahi tikanga ki te tīmata i te pūnaha i roto i te mahi i roto i ngā āhuatanga tino.

mahia rauemi

Kei te hanga piha ahi i maka rino, me te parahi. Ko e tika ana ki te meka e kia riro te kaha, me te tika taua tuhinga tenei. Rino, te parahi, me te taua āhuatanga rerekē, ara anticorrosive, mauroa me te kaha ki te tu i te pēhanga tiketike o te pūnaha. Enei āhuatanga tukua te whakamahi o taua hua mo te wa roa.

tohu

E whakaaturia ngā āhuatanga Crane i pukapuka, pānui mamati kore anake, engari ano hoki i roto i te huru, me te tinana peita tae. Ko te tohu tono e te makanga a me i roto i te raraunga e whai ake nei:

• diameter iti;
• pēhanga iti;
• rauemi casing;
• waitohu ingoa o te kaiwhakanao, me / ranei;
• aronga o te reo whakahaere;
• tau;
• pere-atatohu ki te aronga o te taiao mahi;
• gaskets ti'araa mō te flange taatiraa, me te pera i runga i. d.

Ko te toe momo o tohu tono i runga i ngā whakaritenga ture me ngā ture.

waehere tae whaki te rauemi i ai hanga whare:

• Black - Kerei, ngohengohe, castings rino kōngohe;
• hina - waro maitai;
• puru - koranu maitai;
• puru - koranu nui maitai, te waikura-ātete me alloys wera-ātete.

I taea te kite te piha, ahi o ratou āhuatanga tino whakaatu te tapanga.

āhuatanga tāutanga me te tiaki

momo rerekē o te hoahoa ka taea te piha o te tukuwai ahi i roto i tetahi tūranga. Rāhuitia te tāutanga o te tōhito raro. I roto i ngā āhuatanga ahi, kia mahi ki te pūnaha supply wai utu, me te ngāwari. I roto i te ohotata, nga tuarua kaute, na te piha kia anake kia whakatuwheratia e 4-6 tahuri. tukua whakaaro Modern ki a koutou te mahi taua mahi, kahore hua atu. A, no te kia kitea pūnaha whakapuru mō turuturu. A, no te tāuta i te piha i runga i te hononga awakeri e tightened me repe gasket te hiri. I mua i te tāutanga, me te āta horoia atu te putorino te paru, me te onepu.

Whakaritenga pūmārō:

• Ka taea e te tāuta e koe te piha mā te whakamahi i te matenga hononga.
• I te kore (ino) o te hiri repe e whakakapia ai.
• Ko te kaupapa ki te whakahinuhinu wā te rakau.
• Test taputapu i ia te wā.
• I te mutunga o te ora papa o te taputapu wāwāhitanga reira, ka tono tangata mo te hangarua.
• Ko te ora ratonga o te mapuni, tei runga i tāutanga tika mahi i me te tiaki.

Tutakina-atu piha ahi - tetahi o te tino nui ngā pūrere pūnaha ahi-whawhai. I runga i tona kounga me te tāuta tika tei runga i te tere, me te taea o tona whakamahi i roto i ngā āhuatanga ohorere. A tei tenei i runga i te ora o te tangata. Na reira, i ata e hinonga rāhuitia te whakamahi o te taputapu ahi-whawhai, e kore te hāngai ngā tuhinga normative.

A, no te hoko i te pūrere pērā i te piha, me tono koe i te tiwhikete o fai. Kia whai whakaaro ki nga tohu i runga i te whānuitanga e tono ki ai reira tika me ahakoa nga ngā hangarau e hiahiatia ana. I roto i kahore kaupapa e kore e tangohia e hua o te take mai nanakia. e kore e ratou rerekē i roto i te kounga e tika ana, me te tika. e kore te mea whakaora i runga i enei hua e tika ana, e tika ti'aturi i runga i te ora tangata, me te hauora ratou.
