Ukwakhiwa kwemibhobho yerhasi ecocekileyo

I. Intshayelelo

Ngophuhliso lwelizwe lamisemiconductorkunye namashishini okwenza undoqo, ukusetyenziswa kweimibhobho yegesi ecocekileyoliya lisanda ngakumbi nangakumbi. Amashishini afana ne-semiconductors, i-electronics, amayeza, kunye nokutya zonke zisebenzisa imibhobho yegesi ecocekileyo ukuya kumaqondo ahlukeneyo. Ngoko ke, ukusetyenziswa kwemibhobho yegesi ecocekileyo Ukwakhiwa nako kubaluleke kakhulu kuthi.

2. Ubungakanani besicelo

Le nkqubo ifaneleka ikakhulu ukufakelwa kunye novavanyo lwemibhobho yegesi kwi-electronics kunye ne-semiconductor factory, kunye ne-welding of thin-walled stainless steel pipelines. Ikwalungele ukwakhiwa kwemibhobho ecocekileyo kumayeza, ukutya kunye nezinye iifektri.

3. Umgaqo wenkqubo

Ngokweempawu zeprojekthi, ukwakhiwa kweprojekthi kwahlula ngamanyathelo amathathu. Inyathelo ngalinye kufuneka lihlolwe ngokungqongqo umgangatho kunye nokucoceka. Isinyathelo sokuqala kukwenziwa kwangaphambili kombhobho. Ukuqinisekisa iimfuno zokucoceka, ukulungiswa kwangaphambili kombhobho ngokuqhelekileyo kuqhutyelwa kwigumbi le-1000-level prefabrication room. Inyathelo lesibini kukufakwa kwisiza; Inyathelo lesithathu luvavanyo lwenkqubo. Uvavanyo lwenkqubo ikakhulu luvavanya amasuntswana othuli, indawo yombethe, umxholo weoksijini, kunye nomxholo wehydrocarbon kumbhobho.

4. Iindawo eziphambili zokwakha

(1) Ukulungiswa ngaphambi kokwakhiwa

1. Lungiselela abasebenzi kwaye ulungiselele oomatshini kunye nezixhobo ezisetyenziswa ekwakheni.

2. Yakha igumbi elakhiweyo elinenqanaba lokucoceka le-1000.

3. Hlalutya imidwebo yokwakha, ulungiselele izicwangciso zokwakha ngokusekelwe kwiimpawu zeprojekthi kunye neemeko zangempela, kwaye wenze iinkcazo zobugcisa.

(2) Ukwenziwa kwangaphambili kwemibhobho

1. Ngenxa yococeko oluphezulu olufunekayo kwimibhobho yegesi ecocekileyo, ukwenzela ukunciphisa umsebenzi we-welding kwindawo yofakelo kunye nokuqinisekisa ukucoceka, ukwakhiwa kombhobho kuqala kufakwe kwigumbi elilungiselelwe ngaphambili le-1000. Abasebenzi bokwakha bafanele banxibe iimpahla ezicocekileyo baze basebenzise Oomatshini kunye nezixhobo zokusebenza kufuneka zigcinwe zicocekile, yaye abasebenzi bokwakha bafanele babe nemvakalelo enamandla yokucoceka ukuze banciphise ukungcoliseka kwemibhobho ebudeni benkqubo yokwakha.

2. Ukusika imibhobho. Ukusika umbhobho usebenzisa isixhobo esikhethekileyo sokusika umbhobho. Ubuso obunqamlekileyo buxhomekeke ngokupheleleyo kumgca we-axis centre yombhobho. Xa usika umbhobho, amanyathelo kufuneka athathwe ukuphepha uthuli lwangaphandle kunye nomoya ongcolisa ngaphakathi kumbhobho. Izixhobo kufuneka zibe ngamaqela kwaye zibalwe ukuze ziququzelele ukuwelda kweqela.

3. Umbhobho welding. Ngaphambi kokudibanisa umbhobho, inkqubo ye-welding kufuneka ihlanganiswe kwaye ifake igalelo kumatshini we-welding othomathikhi. Iisampuli ze-welding zovavanyo zinokufakwa kuphela emva kokuba iisampuli zifanelekile. Emva kosuku olunye lwe-welding, iisampuli zinokudityaniswa kwakhona. Ukuba iisampuli zifanelekile, iiparitha ze-welding ziya kuhlala zingatshintshi. Igcinwe kumatshini we-welding, kwaye umatshini we-welding ngokuzenzekelayo uzinzile kakhulu ngexesha le-welding, ngoko umgangatho we-weld nawo ufanelekile. Umgangatho we-welding ulawulwa yi-microcomputer, enciphisa impembelelo yezinto zomntu kumgangatho we-welding, iphucula ukusebenza kakuhle, kwaye ivelise i-welds ephezulu.

4. Inkqubo ye-welding

(3) Ufakelo kwisiza

1. Ufakelo kwisiza lwemibhobho yegesi ecocekileyo kufuneka icoceke kwaye icoceke, kwaye abafakeli banxibe iiglavu ezicocekileyo.

2. Umgama wokubeka umgama weebakaki kufuneka uhambelane neemfuno zokuyila imizobo, kwaye indawo nganye emiselweyo kufuneka ifakwe kwi-sleeve ekhethekileyo ye-rubber yombhobho we-EP.

3. Xa iipayipi ezenziwe ngaphambili zithunyelwa kwindawo, azikwazi ukubethelwa okanye zinyathelwe, kwaye azikwazi ukufakwa ngokuthe ngqo phantsi. Emva kokuba izibiyeli zifakwe, iipayipi zixinzelelwe ngokukhawuleza.

4. Iinkqubo ze-welding pipeline kwi-site ziyafana nezo zikwinqanaba le-prefabrication.

5. Emva kokuba i-welding igqityiwe kwaye abasebenzi abachaphazelekayo baye bahlola iisampuli ezidibeneyo ze-welding kunye ne-welding joints kwimibhobho ukuba ifaneleke, faka ileyibhile ye-welding joint kwaye ugcwalise irekhodi ye-welding.

(4) Uvavanyo lwenkqubo

1. Uvavanyo lwenkqubo luyinyathelo lokugqibela lokwakhiwa kwegesi ephezulu. Kuqhutyelwa emva kokuba uvavanyo loxinzelelo lwepayipi kunye nokuhlanjululwa kugqityiwe.

2. Irhasi esetyenziselwa uvavanyo lwesistim yeyokuqala kuzo zonke iigesi ezifanelekileyo. Ukucoceka, umxholo we-oksijini, indawo yombethe kunye ne-hydrocarbons yegesi kufuneka ihlangabezane neemfuno.

3. Isalathisi sivavanywa ngokuzalisa umbhobho ngegesi efanelekileyo kunye nokulinganisa ngesixhobo kwindawo yokuphuma. Ukuba irhasi ephuma kumbhobho ifanelekile, ithetha ukuba isalathisi sombhobho sifanelekile.

5. Izinto eziphathekayo

Imibhobho yerhasi ecoceke kakhulu ngokuqhelekileyo isebenzisa imibhobho yentsimbi ecekethekileyo enodonga ngokweemfuno zenkqubo yendawo ejikelezayo, ngokuqhelekileyo i-316L (00Cr17Ni14Mo2). Kukho ubukhulu becala izinto ezintathu zealloy: chromium, nickel, kunye nemolybdenum. Ubukho be-chromium buphucula ukuxhathisa kwe-corrosion yensimbi engenasici kwimidiya ye-oxidizing kwaye yenza umaleko wefilimu ye-oxide ene-chromium; ngelixa ubukho be-molybdenum buphucula ukuxhathisa kwe-corrosion yensimbi engenasici kwi-non-oxidizing media. Ukumelana nokubola; I-Nickel yinto yokwenza i-austenite, kwaye ubukho babo abuphuculanga kuphela ukuxhathisa kwentsimbi, kodwa kuphucula inkqubo yokusebenza kwentsimbi.
