Chubu Chosungunula Chokhala ndi Magwiridwe Odalirika

Chitoliro Chokulungira Chubu Chokhala ndi Magwiridwe Odalirika Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Ukadaulo uwu umagwiritsa ntchito kutentha kwambiri kuti upange mgwirizano wolimba komanso wokhazikika pakati pa mapaipi, kuonetsetsa kuti zinthu zathu zimapereka magwiridwe antchito odalirika ngakhale m'malo ovuta kwambiri. Kaya muli mumakampani opanga gasi wachilengedwe kapena mukufuna njira zodalirika zogwiritsira ntchito mapaipi pazinthu zina, mapaipi athu adzakwaniritsa zomwe mukuyembekezera.

Ubwino wa Kampani

Fakitale yathu ili ku Cangzhou, Hebei Province, ndipo takhala patsogolo popanga mapaipi achitsulo abwino kwambiri kuyambira pomwe tidakhazikitsidwa mu 1993. Fakitale yathu ili ndi malo okwana masikweya mita 350,000, okhala ndi chuma chonse cha RMB 680 miliyoni, amatha kupanga matani 400,000 a mapaipi achitsulo chozungulira pachaka, ndipo ali ndi akatswiri 680 aluso.

Chiyambi cha Zamalonda

Kudzipereka kwathu kuchita bwino kwambiri kumawonekera mu njira yathu yowotcherera ya arc, yomwe ndi gawo lofunika kwambiri popanga chitoliro chathu chowotcherera chozungulira. Ukadaulo uwu umagwiritsa ntchito kutentha kwambiri kuti upange mgwirizano wolimba komanso wokhazikika pakati pa mapaipi, kuonetsetsa kuti zinthu zathu zimapereka magwiridwe antchito odalirika ngakhale m'malo ovuta kwambiri. Kaya muli mumakampani opanga gasi wachilengedwe kapena mukufuna njira zodalirika zogwiritsira ntchito mapaipi pazinthu zina, mapaipi athu adzakwaniritsa zomwe mukuyembekezera.

Poganizira kwambiri za ubwino ndi luso, timadzitamandira popereka ma weld a mapaipi omwe amatsimikizira kuti zinthu zikuyenda bwino kwa nthawi yayitali. Sikuti timangochita zinthu zathu zokha.chitoliro chozungulira cholumikizidwaZamphamvu komanso zolimba, komanso zimagwira ntchito bwino kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pa ntchito zomwe zimafuna kudalirika komanso kulimba.

Mbali yaikulu

Chimodzi mwa zinthu zofunika kwambiri pa kuwotcherera machubu ndi kudalira kwake pa kuwotcherera machubu a arc, njira yomwe imagwiritsa ntchito kutentha kwambiri kuti ipange kulumikizana kolimba komanso kolimba pakati pa machubu achitsulo. Njirayi ndi yofunika kwambiri kuti zinthu zomaliza zikhale zodalirika komanso zodalirika, makamaka pakugwiritsa ntchito komwe chitetezo ndi magwiridwe antchito ndizofunikira kwambiri, monga mayendedwe a gasi wachilengedwe.

Njira yolumikizira arc imaphatikizapo kusungunula m'mphepete mwa chitoliro ndikuchiphatikiza pamodzi, kupanga kulumikizana kosasunthika komwe kumatha kupirira kuthamanga kwambiri komanso mikhalidwe yovuta kwambiri. Njirayi sikuti imangowonjezera mphamvu ya chitolirocho, komanso imawonjezera nthawi yake yogwirira ntchito, zomwe zimapangitsa kuti ikhale chisankho chomwe chimakondedwa kwambiri pa ntchito zosiyanasiyana zamafakitale.

Kuphatikiza apo, kulondola ndi ukatswiri wofunikira pakuwotcherera mapaipi kumasonyezanso kudzipereka kwa kampaniyo pakupanga zinthu zabwino. Mwa kuyika ndalama muukadaulo wapamwamba komanso antchito aluso, fakitale ya Cangzhou imaonetsetsa kuti chitoliro chilichonse chowotcherera chozungulira chikukwaniritsa miyezo yokhwima yamakampani, zomwe zimapatsa makasitomala mtendere wamumtima komanso chidaliro pa chinthucho.

Ubwino wa Zamalonda

Chimodzi mwa ubwino waukulu wa kuwotcherera machubu ndi kuthekera kwake kupanga maulumikizidwe olimba omwe amatha kupirira kupsinjika kwakukulu komanso mikhalidwe yovuta kwambiri. Izi ndizofunikira kwambiri mumakampani opanga gasi wachilengedwe, komwe kulimba kwa mapaipi ndikofunikira kwambiri. Njira yowotcherera arc imatsimikizira kutichotchingira chubuSikuti ndi yolimba kokha komanso imagwirizana, zomwe zimachepetsa chiopsezo cha kutuluka kwa madzi ndi kulephera. Kuphatikiza apo, kugwira ntchito bwino kwa kuwotcherera machubu kumathandiza opanga kupanga mwachangu mapaipi ambiri achitsulo chozungulira kuti akwaniritse kufunikira kwa msika komwe kukukulirakulira.

Zofooka za Zamalonda

Njirayi imafuna antchito aluso komanso kuwongolera molondola magawo a zolumikizira kuti apewe zolakwika monga kutseguka kapena kusowa kwa kusakanikirana. Mavutowa amatha kuwononga ubwino wa chinthu chomaliza ndikuyambitsa zoopsa zomwe zingachitike.

Kuphatikiza apo, kutentha kwambiri kwa arc welding kungayambitse kupsinjika kotsalira muzinthuzo, zomwe zingakhudze magwiridwe antchito a payipi kwa nthawi yayitali.

Kuwotcherera Chitoliro Chodzichitira Pawokha

Mafunso Ofunsidwa Kawirikawiri

Q1: Kodi kuwotcherera kwa arc ndi chiyani?

Kuwotcherera arc ndi njira yomwe imagwiritsa ntchito kutentha kwambiri komwe kumapangidwa ndi arc yamagetsi kuti isungunuke ndikulumikiza mapepala achitsulo pamodzi. Pa chitoliro chowotcherera chozungulira, njira iyi ndi yofunika kwambiri kuti pakhale kulumikizana kwamphamvu pakati pa mapaipi, zomwe ndizofunikira kwambiri pakugwira ntchito ndi moyo wa chitolirocho.

Q2: N’chifukwa chiyani kuwotcherera kwa arc ndikofunikira pa mapaipi a gasi wachilengedwe?

Mapaipi a gasi lachilengedwe ayenera kukwaniritsa miyezo yokhwima yachitetezo ndi kudalirika. Njira yolumikizira arc imatsimikizira kuti malo olumikizirana amatha kupirira kupsinjika kwakukulu ndikupewa dzimbiri, zomwe zimapangitsa kuti ikhale yoyenera kunyamula gasi lachilengedwe mtunda wautali.
