Tiaki Cathodic o paipa waikura: te taputapu, te parau tumu whakahaere

Founga o te tiaki ki te waikura , ki te whakawhānui i te ora mahi o ngā hanganga whakarewa, me te ki te mau tonu ona āhuatanga hangarau me te tinana i roto i te mahi. Ahakoa te momo o tikanga ki te whakarite mahi anti-waikura, tino tiaki i ngā i te whakangaromanga e waikura ko reira taea anake i roto i te wā onge.

Ko te whai huatanga o taua tiaki tei runga i te kounga o te hangarau takahi kore anake, engari ano hoki i tikanga o tona tono. I roto i ngā, i te penapena hanganga whakarewa te whakatangi te ratou āhuatanga pai whakaatu tiaki iahiko ki te waikura i runga i te cathodes. Ārai i te hanganga o te waikura i runga i enei kōrero ko, o te akoranga, e kore anake te mara o te tono o tenei hangarau, engari ki runga ki te katoa e taea te i titiro nga āhuatanga o tenei rohe rite te rironga ko iahiko tino hāngai ana.

He mahara ki te tiaki iahiko

hāngai ana Parenga o konganuku ki waikura i te tikanga o te maimoatanga iahiko kei i runga i te fakafalala o te pūmanawa kawehiko o te rauemi i te tere o te tukanga waikura. Me whakahaeretia ngā hanganga Metal i roto i te whānuitanga pea te wahi ratou whakakorenga anodic ko raro te tepenga. Te whakamutunga, rokohanga, e whakaritea e te tuhinga hangarau mō te mahi o te whare.

I roto i te mahi, te tiaki te waikura iahiko tā tūhono ki te hua oti ki te puna o nāianei tamau. Ko te mara hiko i te mata, me te i roto i te hanganga o te ahanoa tiakina mahia e electrodes vahiraa, e tika ana ki te te waikura, me te mana e te tukanga whakangaromanga. I roto i te meka, te wāhi anodic i runga i te hanganga konganuku riro te pitoiho, tuku ki teke'i te tukanga tōraro, te whakarite i te haumaru o te hanganga ūnga.

Ko te parau tumu whakahaere o te tiaki cathodic

He he cathodic me anodic tiaki o te momo iahiko. Ko te tino rongonui ano riro te ariā tuatahi, whakamahia nei te ki te tiaki i nga pipelines. Ka rite ki te parau tumu whānui, te whakatinanatanga o tenei tikanga, tukua te ahanoa te ki o nāianei i te pou tōraro o te pūtake waho. I roto i ngā, te kupu e taea te tiaki i te reira maitai ranei parahi ngongo, ai te vahiraa pitoiho ka puta ki nga wahi whakawhiti o ratou moe, i roto i te āhua pitoake. Ka rite ki te hua, ka kia heke waikura tiakina mahi hanganga ki tata te kore.

I te wa ano, kia whai me te tiaki cathodic putanga rerekē. Kei te whānui te tikanga i runga ake-whakaahuatia mahi vahiraa i te pūtake waho, engari mahi te kawehiko tōtika me te tikanga deaeration ki whakaiti tukanga cathodic tere, me te te hanganga o te arai takahi.

Kua toutou kitea reira e te kitenga i te parau tumu o te tiaki cathodic e te pūtake o nāianei waho. Mau, i roto i tona mahi, ko te mahi matua o te tiaki waikura. Te mahi i enei mahi teihana motuhake, e e te nuinga o ngā i roto i te katoa tiaki hanganga paipa hangarau.

Teihana o te tiaki cathodic ki te waikura

Ko te mahi matua o te teihana pitoiho te stably whakarite te ahanoa whakarewa hiahiatia i roto i runga i te tikanga o te vahiraa cathodic nāianei. Whakamahia taua taputapu i roto i te hanganga o te hau raro, me te hinu pipelines, paipa wai, ngā pūnaha whakawera me etc.

He maha ngā momo o ngā mātāpuna, te pūrere tino noa whakarato mo te tiaki cathodic arā o:

• DC taputapu converter;
• Waea Ōseni ki te ahanoa tiaki;
• Pitoake.

I roto i tenei take, i reira he he inverter teihana wehenga me te hiko. He atu whakarōpūtanga, engari Kei te arotahi ratou i runga i wae whakawāhanga, ranei whānui, ranei i runga i nga āhuatanga hangarau me ngā tawhā o te raraunga tāuru. te mau parau tumu Basic o te mahi tino mārama whakaatu te tohu teihana cathodic rua.

tāutanga hiko o te tiaki cathodic

Tonu kia tuhia te reira e tenei momo o teihana he tawhitotia. I tona neke mai tika analogues inverter, e whai e rua pluses me minuses. Heoi, kei te whakamahia ngā tauira hiko noa i roto i ngā kōwae hou whakarato tiaki cathodic.

Ka rite ki te pūtake o taua taonga whakamahia te he iti-auau hiko 50 Hz thyristor converter. pūrere Simple, pērā i pini-wāhanga mana tikanga mo te pūnaha mana thyristor. He huarahi atu haepapa ki te mahi whakahaere tā te whakamahi o ngā pūmana ki taumahinga whanui.

Modern tiaki te waikura cathodic o pipelines i taua taputapu taea ki te whakatika i nga tawhā o te nāianei putanga, tohu ngaohiko, me te ki te hāngai te moe, tiaki. Na i runga i huakore o transformers, kua heke ratou ki te nui rawa o te pōkare nāianei i runga i te putanga ki te take mana iti. Ua faataa te reira i e kore ko te koha he puka nāianei poipoi aho.

Te whakaoti i te raruraru o te pōkare ki te whānuitanga etahi ka taea te whakataki o te pūnaha kowaowaotia iti-auau, engari hāngai ona āhuatanga ki te āhuatanga o te hiko, e kore te mea e tonu taea ki te hanga i te tua taua.

teihana Inverter tiaki cathodic

tāutanga inverter i runga i pūtahuri tiketike-auau pākau i. Ko tētahi o nga painga matua o te whakamahi i ngā tipu o tenei momo ko te tōtika tiketike, pa tonu 95%. No te whakarite, te wae hiko, tenei ahua he toharite o runga ki 80%.

I te tahi taime mai ki te mua, me ētahi atu painga. Hei tauira, whakawhānui teihana āhuatanga iti inverter whai wāhitanga mō rātou tono ki ngā wāhi uaua. He hoki painga pūtea, e haapapu te mahi o te whakamahi o taua taputapu. Ko te kupu, ko te inverter cathodic tiaki te waikura o pipelines utu atu hohoro a titau haumi iti i roto i te tiaki. Heoi, ko enei 'ulungaanga mārama kitea anake ka whakaritea ki te tāuta hiko, engari i tenei ra i reira e whai hua ake tikanga hou o te whakarato te mana mō pipelines.

teihana cathodic Hoahoa

māngai taua taputapu kei i runga i te mākete i rerekē whare, āhua me te rahi. O te akoranga, mahi noa me te hoahoa takitahi o taua pūnaha, e taea ai e koe te tiki i kore anake te pai mo nga hiahia motuhake o te hanganga, engari ano hoki ki te whakarato i te tawhā whakahaere e tika ana.

Tino āhuatanga teihana tātaitanga atu taea ki te arotau i te utu o tona tāutanga, transportation, me te rokiroki. Hei tauira, mō ngā taonga iti rawa e tika ana te tiaki te waikura cathodic o pipelines i runga i te pūtake o te inverter taimaha 10-15 kg me te mana o te 1.2 Kw. Taputapu ki taua āhuatanga e taea te serviced me te motokā, engari mo te kaupapa nui-tauine e taea e atu nui, me te taimaha tipu, tono i te hononga o taraka, he warou me te rōpū o installers.

taumahinga paruru

utua ngā aro te ki te whanaketanga o teihana tiaki cathodic o te taputapu iho. Hoki tenei pūnaha integrated, tuku i te teihana ki te tiaki ki haaati me naianei kawenga poto. I roto i te take tuatahi whakamahi tatou whakaaro haumaru motuhake, tuku ki te tukatuka i ngā tautuhinga mahi whawhati tata.

Ko hūpeke me pakaru ngaohiko, te teihana o te tiaki cathodic he pea ki te kia tino pāngia e ratou, engari i reira ko te mōrea o te ru hiko. Hei tauira, ki te whakahaeretia te aratau noa e taputapu ngaohiko iti, i muri i te peke i roto i ngā tohu naianei e taea kawea ki te 120 V.

Ētahi momo o te tiaki iahiko

I tua atu ki te tiaki cathodic me hiko pana wai hangarau mahi me tikanga ārai waikura tusia. whakaaro te wāhi tino whaihua te ki he Tuhinga motuhake i waikura, me te waikura. I roto i tenei take hono ano hoki ki te ūnga āhuatanga kaha e tukua faafariuraa o te mata o te cathodes i te nāianei. Hei tauira, e taea te tiaki putorino maitai rite te wahi o te paipa ki te konutea konumohe ranei ipurau.

mutunga

e kore e taea te pēnei tikanga o te tiaki iahiko ki te hou, me te ake auaha. Ko te tōtika o te whakamahi o taua tikanga i roto i te whawhai ki ngā tukanga waikura taukei roa i mua. Heoi, ko te whānui o tenei tikanga tohatoha ārai kotahi drawback nui. Ko te take i te tiaki cathodic o pipelines i te waikura te taniwha, whakawhanake pera-ka karanga ngā kotiti. e kore e kino ki te hanganga ūnga ratou, engari kia whai i te pā tōraro i runga i ngā tata. I roto i ngā, whai wāhi te nāianei vagus ki te waikura ano i runga i ngā mata konganuku o nga korere pātata.
