Warming kawehiko raima i roto i te hotoke

tau te tatini ki muri, tata ngaro mahi hanga katoa ratou kaha i roto i te wa hotoke. Ko reira e tika ana, te tuatahi, me te roa, haunga pāmahana. Otiia ki te i mahana kakahu nga kaimahi, me te, konei ki te mahi i te concreting i taua mau huru, ko reira tino raruraru. Otiia i muri i te ia i reira ko tetahi ara rawa whai hua - ngā kawehiko raima mahana, me te whakamahi i taura hiko. Kia tango o te titiro i te āhuatanga o tenei tikanga, ka kōrero e pā ana ki tona whaihuanga.

Aha e rave i te reira?

I mua i te hi'opoa maite ki tenei kaupapa, ko reira tika ki te kōrero e pā ana ki, hoki te mea kei te mau whakamahia. Ko te meka e roto i tetahi raima he nui tetahi o te wai. Noatia, te pāmahana iti-kore, hanga reira tioata. Ko te ahu whakamutunga ki te meka e te pēhanga nui i runga i nga kōputaputa raima, e te mutunga arata'i ki te whakangaromanga wāhanga katoa ranei o te hanganga. Kei te tino iti te kaha hopea, a ino roa mahi.

Ko tētahi atu pūmate - mīti o te wai i roto i te tautuhinga wā (solidification). Ko te take i ki te pāmahana tauhohenga iti o te ranunga raima, me te wai pakanga te. whakairihia ana te reira i te tukanga solidification, hanga pāhiwihiwi reira. Ko ki te mea e kore te mea e tika ana i te kaha whakapuakina. Otiia, i tenei ra e kore te mea i reira he electrodes whakawera taiawhio raima, e taea ai e koe te pupuri i nga āhuatanga takawai-pāmahana i roto i te whānuitanga tīkina.

I runga i nga tikanga o te concreting hotoke

Ko reira utu aufauraa i te whakarongo ki te meka, e pā ana ki te kawehiko ki te rā e kore e anake. Ko e tika ana ki te meka i ētahi wā e kore he e tika ana tenei tikanga ranei tona whakamahinga utu ngā utu rawa tenei. Ano, nui tei runga i te tikanga (pāmahana, haumākū, faaue hoahoa heke mai). Hoki tenei take ohie, i reira e rave rahi atu huarahi o concreting i te hotoke. Hei tauira, whakawera i roto i te formwork whakawera. Ko te tino whai hua, me te pai tenei tikanga, engari he tika anake hoki te matotoru iti. Na roto i te waenganui o te raima, ka tonu tio he iti, me te aha he reira nui, ka hei te pānga whakarihariha pāmahana tōraro. Ano i reira tāpiritanga ārai makariri, hanga i te ranunga atu ātete ki te haupapa. He he he whakawera arataki me waea motuhake. Ko te tikanga tino rongonui ko te whakamahi o electrodes.

A, no te whakamahi i electrodes?

whakamahia ia o nga tikanga i runga ake te i roto i te āhuatanga ngā. Ko te kawehiko, na ehara i te mea he otinga ao. Hei tauira, ko reira tino whai hua, ka maka ana i te papa raima. I roto i tenei take, ko te reira pai ki te tono i te waea whakawera. Otiia ki te e korero tatou e pā ana ki te hanganga poutū, konei te whakawera kawehiko ko te otinga pai.

E te ara, i ētahi wā te whakamahi i mātao tūturu, e te mea maha e kore e nui. I roto i tenei take, he pai hei whakamahana atu te kawehiko. Ko ti'a ia tatou ia maramarama e, te hanganga whānui, te tōtika o raro me utu teitei, engari ki tenei wāhi ka hoki mai tatou. Aua'e, te hangarau whakawera raima i roto i te taua ara taukei a whakamahia whānuitia e te kaihanga i huri noa i te ao. Heoi, i roto i Russia te nuinga o ngā whare whakamahi waea whakawera.

I runga i nga painga o tenei tikanga

Me kï reira e te tikanga te kawehiko hangarau whakawera raima 3 anake kaimahi. Ko te painga nui tenei no te mea e kore e hiahia ana te reira i te rota o te iwi. I tua atu, kia mea ai e pā ana ki te whai huatanga o te tikanga. Tenei otinga whakarato kore noa te tautuhinga ranunga kākahu, engari e kore e ofati i te tapatahi o te hanganga. Ko te tino he wāhi nui tenei, no te mea he tauwehe taua he pānga tika i runga i te kaha me te mauroa o te hua. Tētahi atu take nui - te tapatahi, me te tere tiketike o te tāutanga. Ko te pono rawa tenei i roto i te huka taimaha. I tua atu, e kore e taea e matou te mea e hoki te tīwae maha nui whakamahi kotahi anake kawehiko.

Kaha titiro matou ki, a inaianei hanga reira tikanga ki te mea e pā ana ki te āhuatanga e konei reira rawa.

Huakore electrodes whakawera

I roto i to tatou take ko reira tika ki te kōrero e pā ana ki te whakamahi rite waea kawehiko tokotoko ngā. Ko te tikanga ka mau ake te diameter 8-10 mm, i te mea e tau mo te mahi whai hua o. e mea he e reira kia kia etahi āhuatanga, engari he ratou.

Tuatahi, ko reira te kohi pūngao rawa nui. ka pau ia kawehiko e pā ana ki 50 A. He mea tika ki te whakamahi i te transformers taahiraa-iho. Hei tauira, e kore te mea pera nui te Kw kume tauira 80. Na reira, i roto i te tua ki te electrodes Me ki te hoko taputapu atu, i te mea tino utu.

Ko tētahi atu drawback nui, no te mea o nei maha ngā hipa tenei tikanga o te rōpū - te utu tiketike. Ko te meka Ko e i te tokotoko e tuku electrodes. I muri i to ratou huinga, noho ake ratou i roto i te hoahoa o te tinana, me te tango kore ko ratou taea. Ko te hunga e tonu faaoti ki te whakamahi i te reira i roto i tenei tikanga, he makona. Kei te tiaki hanganga kaha mo te wa roa, me ko te mahi i te taumata tiketike.

E painaina ana electrodes raima: Hangarau

Na kia a titiro poto ki te mauri o tenei tikanga. Ka rite ki tuhia i runga ake, e kore te mea te reira e tika ana mō te ringihia te papa raima anake hoki tīwae, taiepa me diaphragms. Kua muri oti te mahi te whakarewanga o te, e whakaurua nga rakau whakarewa ki te taiepa. E tukua ana ratou ki te ngaohiko mā te hiko taahiraa-iho. Ko te tikanga tīpakohia wā i waenganui i rua electrodes pātata o 60 ki te 100 henimita, e tei runga i te rangi me te ahanoa whirihoranga.

Ki te tukua hiko taahiraa-iho te ki te piha e toru ngā wāhanga, ai mahana te wāhi i waenganui i te electrodes te ka whakakorea mīti te. Ko reira utu aufauraa i te whakarongo ki te meka i hāngai te whakawera o te raima i roto i te hotoke i runga i te wahi o te nāianei hiko i roto i te wai i roto i roto i te otinga. Ko te hua ko te whakawera ōrite. E koe ki te matau, ki te reira ko te whare herehere te whakaū, e kore e te ngaohiko e neke atu i te 127, a ki te kore e tīari reira, e taea te whangai te reira 220 me 380, engari e kore e ake.

Ngā momo o electrodes whakamahia

I tēnei wā, e toru ngā momo o electrodes whakamahia. he e tika ana mō ngā āhuatanga rerekē ia o ratou. Hei tauira, kei te hanga nga electrodes tokotoko e te hunga i roto i te rongonui tino i armature 8-12 mm te whānui. Ko te tinana raima e whakanohoia e ratou ki te taahiraa tatau, whakaritea nei i roto i te mua. tāuta raupapa Ultra kahore tata atu i te 3 cm i te casing e whakarite whakawera tonu taiepa mata tīwae ranei. Ko reira taa'eraa i he reira e tika ana mō te whakaaro āhua tino matatini taua electrodes.

Ko te electrodes pereti rerekē te mahi he iti. E whakairihia ratou i tetahi taha o te formwork. hanga tenei he mara hiko e heats te raima ki te pāmahana e hiahiatia ana mo te wa tomu'a. I roto i te parau tumu, Ko te tino whai hua te tikanga taua o te whakawera i te raima i roto i te hotoke. Kei te pai ngā waka electrodes Aho mō ngā hanganga pēnei i tīwae.

electrodes warming raima: waea hoahoa

kia mohio ki te reira e ka rerekē te whakawera hiko o te tikanga hononga i runga i te momo o te kawehiko rānei. A, no te mahi ki electrodes paraharaha, tukua tetahi wāhanga e ki te kawehiko tuatahi me te tuarua kei i te taha ki te ritenga atu. Ka rite ki te hua, to tatou e rua electrodes, e he whakarara ki tetahi ki tetahi, i wāhanga ia. I roto i te take o te rakau whakaū e hono ki tetahi wāhanga o te tuatahi, me te whakamutunga i roto i te raupapa o electrodes. Etahi mahi e te 2, me ngā wāhanga 3.

Me kï reira e kore e tau'a ore koe i te tāutanga o transformers. Ko ratou i roto i ētahi wā e kore e tika, engari i roto i te nuinga o ngā āhuatanga hanga reira tikanga ki te tāuta ratou. Hei tauira, he raima pāmahana whakawera tino pai, e kore te mea tiketike rawa e, te kore ai riro koe taua pānga houhou rite overdrying. Hoki tenei take ohie, hanga ana e ia te tikanga ki te huihuia katoa o nga electrodes roto i te hiko taahiraa-iho.

elekrodami wera: ture nui

Hoki te mahi pai o te whakawera hiko, me kia hono koe ki amo rerekē o te kaha. Ko te tino nui ki te mahi i rite ki te whakamahi koe i te wāhanga kotahi tenei ture, e kore te hua.

I tua atu, e te ara iahiko wahi i roto i anake te raima mākū. Hoki ia take utu ake he kaupapa motuhake, e tohu te ware i waenganui i nga electrodes, te whakaritenga transformers taahiraa-iho, me te ngaohiko whakatauranga.

Ko reira utu aufauraa i te whakarongo ki te meka e ngaro to ratou kaha etahi rama o raima. Hei tauira, kei te whakaaro manakohia te mate o 20-25%. Heoi, i mua i te tīmata koe i te whakawera tukanga o te raima, e tūtohu ana hoki etahi wa ki te mau tonu i te reira, kahore whakawera.

torutoru kōrero

Tenei ko matou ki a koutou, a ka titiro ki te mea electrodes whakawera raima. Ka taea e te hangarau rerekē i runga i te electrodes rānei. Heoi, kia tuhia te reira e ki te whakapai ake i te kounga me te kaha o te ranunga whakamutunga raima te'aonga ki te whakamahi i ngā tāpiritanga motuhake. Hei tauira, konupūmā pūhaumāota, tāpiri i te para, Portland sima, te whakaiti i te mate o te kaha, me te wa he pakeke hoki i te 20-30%. Ki te kite tatou e ara i roto i te aroaro o te hiko taahiraa-iho he whakamaroke reira, kia makuku te mata ki te wai mono i te whakaatu mo te ia ranei.

mutunga

Tenei ko matou ki a koutou, a ka titiro ki electrodes whakawera raima. Hangarau, rite tuhia i runga ake, tīpakohia te i runga i te kaupapa takitahi, Kei te whakawhanakehia e mo ia take motuhake rānei. Tenei whakaora kore anake te wa, me te moni te kaiwhakawhanake, engari electrodes ano optimally whakanohoia, me te tino tere ake te tukanga haamărôraa o te ranunga raima. I te tahi taime he mea tika ki te whakamahi i ētahi atu tikanga whakawera, pērā i waea whakawera. O te akoranga, ko reira tino utu, engari tino whai hua. Fele, Ko reira te kōrero katoa i runga i tenei kaupapa. Kia mahara e te tūranga matua takaro e hangarau haapa'oraa i roto i te tāutanga o te whakawera hiko.
