Ukulungiselela Izinto Eziluncedo

Ukulungiswa kwezinto ezibonakalayo kubonisa ukuqala kokwakhiwa kwesakhiwo sensimbi, kwaye umgangatho wayo uchaphazela ngokuthe ngqo zonke iinkqubo zokusebenza ezilandelayo. Imisebenzi ephambili kweli nqanaba ibandakanya ukwamkelwa kwezinto eziphathekayo, ukulungiswa kunye nokucoca indawo. Emva kokuba izinto zentsimbi zifike kumzi-mveliso, izatifikethi zazo zemathiriyeli ziya kujongwa ngokuchasene nemveliso yokwenyani. Ukuphinda kuhlolwe ukwakheka kweekhemikhali kunye neempawu zomatshini ziya kuqhutywa kwiintsimbi ezisetyenziswe kumacandelo amakhulu okwakhiwa. Iintsimbi ezigogekileyo ezibangelwa ngexesha lothutho ziya kulungiswa kusetyenziswa i-roller straighteners okanye oomatshini be-hydraulic jacking. Amava abonisa ukuba malunga nama-80% eempazamo zobude obungabhalwanga buphuma kwimathiriyeli ekrwada engalungiswanga.

Lofting

I-Lofting linyathelo lokuqala elibalulekileyo lolawulo oluchanekileyo kwimveliso yesakhiwo sentsimbi. Kumaqonga anikezelweyo okanye iitafile zokuyila, amagcisa azoba amakhonkco amacandelo apheleleyo kunye neenkcazo ngokomlinganiselo we-1: 1 ngokuhambelana nemizobo yoyilo ukuchaza iimilo zamalungu. Ukongeza ekuqinisekiseni ubungakanani bomzobo, isibonelelo se-welding shrinkage siya kugcinwa njengoko kufunwa ziinkqubo ezifanelekileyo. Ngokuqhelekileyo, isibonelelo se-1 ukuya kwi-1.5 millimeters siya kubekelwa bucala kwi-butt weld nganye.

Ukumakisha

Eyaziwa nangokuthi i-scribing, ukumakisha kubhekisela kwinkqubo yokusebenzisa iitemplates ukuphawula izikhundla zomngxuma kunye nemigca ye-machining yeenkcazo zecandelo kwiiplate zetsimbi kunye namacandelo. Umgaqo othi "amalungu amakhulu kuqala, amancinci emva koko" uyalandelwa ukunyusa izinga lokusetyenziswa kwezinto. Ngoyilo oluphuculweyo, umgangatho wokusetyenziswa kwezinto ngokubanzi unokufikelela ngaphezulu kwe-85%, kwaye unokude ugqithe kwi-92% emva kokwenziwa kwendlwane.

Ukusika

Ukusika yinkqubo yokwahlula iimathiriyeli ekrwada zibe ngamalungu ahlukeneyo ngemigca ephawulweyo. Iindlela zokusika eziqhelekileyo ziquka ukusika igesi, ukusika i-plasma kunye nokusika kwe-laser. Ukusetyenziswa ngokubanzi kweteknoloji yokusika ukulawulwa kwamanani kuye kwaphucula ukuchaneka kunye nokusebenza kakuhle kwesakhiwo sensimbi. Ezinye iindawo ezisikiweyo zifanelekile ukuwelda ngokuthe ngqo ngaphandle kokusetyenzwa komphetho wesibini.

Ukubumba

Amalungu angengawo migca afana nemiqadi egobileyo kunye nemibhobho egobileyo iya kubunjwa ngokugoba okubandayo okanye ukugoba okushushu. Ukugoba okubandayo kwenziwa kwiqondo lobushushu begumbi kwaye kusebenza kumacandelo aqhelekileyo agobileyo. Ukugoba okutshisayo, iintsimbi zifudunyezwa kwi-900-1100 ° C ngaphambi kokugoba, ezamkelwa ngamacwecwe angqingqwa okanye amacandelo anerediya yokugoba encinci.

INdibano

INdibano ithetha ukudibanisa iinxalenye ezicwangcisiweyo njengoko zifunwa yimidwebo kunye nokulungisa okwethutyana nge-tack welding. Inkqubo yokudibanisa esemgangathweni imi ngolu hlobo lulandelayo: Gaya imithungo yeepleyiti zeflange → Susa iibhula kwiipleyiti zewebhu → Fikelela kwindawo echanekileyo ngomatshini wokuhlanganisa → Gqibezela ukudityaniswa kwentsimbi yecandelo elinye le-T → Flip idibaniso kwaye ugqibezele ukubumba ngokubanzi.

Ukuwelda

I-Welding yinkqubo engundoqo yokwenziwa kwesakhiwo sentsimbi kunye neemfuno eziphezulu zobugcisa kunye nokulawula umgangatho ongqongqo. Iindlela ze-welding ezisetyenziswa ngokuqhelekileyo ziquka i-arc ye-arc ezenzekelayo, i-CO₂ i-gas shielded welding kunye ne-shielded metal arc welding.

Ukuqondisa

Uxinzelelo lwe-thermal oluveliswa ngexesha le-welding luya kubangela ukuguqulwa kwecandelo, eliya kupheliswa ngokulungelelanisa ukubuyisela ubume bejometri yasekuqaleni. Iindlela eziqhelekileyo zokulungelelanisa ziquka ukulungelelanisa oomatshini, ukulungiswa komlilo kunye nokudibanisa okudibeneyo. Ukufudumala kwindawo efanayo akuyi kuqhutywa ngaphezu kwamaxesha amathathu, kwaye ukufudumala kunqatshelwe ngokungqongqo.

Ukuhlolwa

Ukuqhuba kuyo yonke inkqubo yokuvelisa, ukuhlolwa kusebenza njengesiqinisekiso esibalulekileyo somgangatho wemveliso. Ukuhlolwa ngezigaba ikakhulu kubandakanya ukuhlolwa kwempahla ekrwada, ukuhlolwa kwenkqubo kunye nokuhlolwa kwe-post-welding. Iziphene ezibulalayo ezifana nokuqhekeka kunye nokudibanisa okungaphelelanga akuvumelekanga ngaphakathi kwe-welds.

Ukwaleka

I-Coating inika i-anti-corrosion kunye nokukhuselwa komlilo kwizakhiwo zetsimbi. Inkqubo yokwaleka eqhelekileyo inemigangatho emithathu: i-zinc-rich epoxy primer, i-epoxy micaceous iron intermediate coat, kunye ne-polyurethane okanye i-fluorocarbon topcoat. Iidyasi ezikwazi ukumelana nomlilo ziya kufakwa kwiidyasi ezininzi ezibhityileyo. Ubushushu be-ambient yokusebenza kokugquma abuyi kuba ngaphantsi kwe-5 ° C, ukufuma okuhambelanayo akuyi kudlula i-85%, kwaye ubushushu bomhlaba wentsimbi buya kuba ubuncinane be-3 ° C ngaphezu kwendawo yombethe.

Ukuhanjiswa kwiFactory

Ukuhanjiswa linyathelo lokugqibela lokwenziwa kwesakhiwo sentsimbi. Amacandelo aphumelele uhlolo lokugqibela aya kunikwa amanani eenombolo ezizodwa kunye namanqaku. Izixhobo ziya kudityaniswa ngokwamaqela ngokulandelelana kofakelo. Iibhloko zokhuni okanye ii-gaskets zerabha ziya kufakwa phakathi kwamacandelo ukuthintela imikrwelo yokwambathisa.
