He huri i hanga o rino: ngā momo me ratou hōkai

I roto i te hoahoa me te hanganga o ngā pūnaha paipa utua tokanga makehe te ki āta me hononga tui i roto i putorino ki diameters rerekē. I roto i te wāhanga e whakamahia ngā pūhui, i huaina nei ko te parahi whakawhiti, me te tuku rere noa o te taiao e mahi ana i roto i ngā tohutohu e rua. Ko tēnei rauemi kei roto i te maha ngā take he tino rongonui. kaiwhakanao Russian hua whakawhitinga maitai paerewa i roto i runga i te GOST 17378-2001 me whakawhitinga motuhake whakahāngai i te hononga e kore he tawhā Waeine hāngai,. E rua ngā momo o mapuni e te tikanga o nei e tāutatia putorino: te rereke me te concentric.

I roto i te take tuatahi, he kokoru neke me te putanga mō tuaka rere inu i te nui iti, e taea tonu whakaawe i te rere o te waka. Here, te raro riro te reira i te wahi o te hononga.

I roto i te take tuarua, ko te parahi whakawhiti korere concentric tauturu hononga whakapiringa, kahore displacement haere te tuaka o te rere mahi.

Rere haere i roto i te wāhi tuwhera o te paipa i roto i te āputa, piki heke ranei, pera e te pēhanga mahi. tei ana tēnei tukanga i runga i te whakawhitinga o te maitai.

Ko te rauemi mo te hanga o te mapuni he rerekē ngā kōeke maitai. Hoki te mahi i roto i te iti te taiao pēhanga me kore-ha'iriiri whakawhitinga maitai e hanga i te waro maitai St3, St10, St20. Ēnei hua whakaputaina i ngā kōeke maitai pērā i 12X18H10T, 15X5M tono ka kawe rere fluids pukuriri, i roto i titonga maitai motuhake e tapiritia ki te whakapai ake i te ātete te waikura, me te mauroa. O te maitai ki te waikura iti hua whakawhitinga ātete maitai ki te paninga konutea i roto i te paparanga kotahi.

He āhuatanga tino o ngā ko te pēhanga mahi mōrahi i runga i te rauemi me ngā tawhā āhuahanga rānei ki te tu pēhanga whakahaere i roto i te whānuitanga o te 4 ki te 160 MPa, e ōrite ana ki te tīkina mōrahi.

Whakawhitinga maitai paiherea hangaia ki te mahi i te pēhanga o te 16 MPa me te faaohiparaa i i pāmahana i -70 ki + 450 ° C, ka e ātete ki te pāmahana, me te pēhanga rerekētanga.
Ka taea e te ngā hangarau production hua ara rebar o takahi ranei e maka ana electroslag turai, whiwhi i te reira tura'i, te whakanui ake i te tika me te ora ratonga.

Whakaritenga ki te rauemi tohutohu tika me te whakaminenga:

- kia whai i te parahi, he ukanga tiketike, hanganga svarimostyu me te taikaha ;

- rua hanganga ture proportionality whakawhiti me te putorino roundness me pereni mutunga mata.

Te kōwhiri i ngā whakawhitinga maitai, kia piri ki te paearu e whai ake nei:

- kokoru me te diameter putorino putanga;

- momo o te rauemi, me ona āhuatanga kaha;

- tiro te reo mahi me te rerekētanga pāmahana;

- pēhanga Whakahaere.
