Tube Weld Nekushanda Kwakavimbika

Kusundira Tube Nekushanda Kwakavimbika Mufananidzo Wakaratidzwa

Tsananguro pfupi:

Tekinoroji iyi inoshandisa tembiricha yakakwira kuti igadzire chisungo chakasimba uye chinogara kwenguva refu pakati pemapaipi, ichiva nechokwadi chekuti zvigadzirwa zvedu zvinopa mashandiro akavimbika kunyangwe munzvimbo dzakaoma zvikuru. Kunyangwe uri muindasitiri yegesi yechisikigo kana uchida mhinduro dzakavimbika dzemapaipi kune mamwe mashandisirwo, mapaipi edu achasangana uye achapfuura zvaunotarisira.

Kubatsira Kwekambani

Fekitori yedu iri muCangzhou, Hebei Province, uye tanga tiri pamberi mukugadzira mapaipi esimbi emhando yepamusoro kubvira patakatangwa muna 1993. Fekitori yedu ine nzvimbo inosvika 350,000 square metres, ine midziyo inosvika RMB 680 miriyoni, inogona kugadzira matani 400,000 emapaipi esimbi anotenderera pagore, uye ine nyanzvi 680 dzine hunyanzvi.

Nhanganyaya yeChigadzirwa

Kuzvipira kwedu kuita zvakanaka kunoratidzwa nemaitiro edu ekushongedza arc, inova danho rakakosha mukugadzirwa kwepombi yedu yakasungirirwa nespiral. Iyi tekinoroji inoshandisa tembiricha yepamusoro kugadzira chisungo chakasimba uye chinogara kwenguva refu pakati pepombi, ichiva nechokwadi chekuti zvigadzirwa zvedu zvinopa mashandiro akavimbika kunyangwe munzvimbo dzakaoma zvikuru. Kunyangwe uri muindasitiri yegesi yechisikigo kana uchida mhinduro dzakavimbika dzepombi dzemamwe mashandisirwo, mapaipi edu achasangana nekupfuura zvaunotarisira.

Tichinyanya kutarisa pamhando yepamusoro uye hunyanzvi hutsva, tinodada nekupa mapaipi ekubatanidza anovimbisa kushanda kwenguva refu.pombi yakasungirirwa yakatendereradzakasimba uye dzinogara kwenguva refu, dzinoshanda zvakanaka, zvichiita kuti dzive dzakakodzera mapurojekiti anoda kuvimbika uye kugara kwenguva refu.

Chinhu chikuru

Chimwe chezvinhu zvakakosha pakushongedza machubhu ndiko kuvimba kwayo nekubatanidza arc, nzira inoshandisa tembiricha yakakwira kugadzira kubatana kwakasimba uye kwakasimba pakati pemachubhu esimbi. Maitiro aya akakosha pakuona kuti chigadzirwa chekupedzisira chakavimbika uye chakavimbika, kunyanya mukushandiswa uko kuchengetedzeka nekushanda kwakakosha, senge kutakurwa kwegasi rechisikigo.

Maitiro ekunamira arc anosanganisira kunyungudutsa mipendero yepombi uye kuibatanidza pamwe chete, zvichigadzira kubatana kusina musono kunogona kutsungirira kumanikidzwa kwakanyanya uye mamiriro akaipisisa. Nzira iyi haingowedzere simba repombi chete, asiwo inowedzera hupenyu hwayo hwekushanda, zvichiita kuti ive sarudzo inosarudzwa kune akasiyana mashandisirwo emaindasitiri.

Pamusoro pezvo, kunyatsorongeka uye hunyanzvi hunodiwa pakupinza mapaipi zvinoratidzawo kuzvipira kwekambani kune mhando yepamusoro. Nekudyara mari muhunyanzvi hwepamusoro uye vashandi vane hunyanzvi, fekitori yeCangzhou inoita kuti pombi dzese dzakasungirirwa dzakatenderedzwa dzisvike padanho rakasimba reindasitiri, zvichipa vatengi rugare rwepfungwa nekuvimba nechigadzirwa.

Kubatsira Kwechigadzirwa

Chimwe chezvakanakira zvikuru zvekugadzira machubhu ndiko kugona kwayo kugadzira majoini akasimba anogona kumira kumanikidzwa kwakanyanya uye mamiriro ezvinhu akaoma. Izvi zvakakosha zvikuru muindasitiri yegasi rechisikigo, uko kusimba kwepaipi kwakakosha. Maitiro ekugadzira arc welding anovimbisa kutiweld yechubhuHaingori yakasimba chete asi inogara iripo, izvo zvinoderedza njodzi yekubuda kwemvura kana kutadza kushanda. Pamusoro pezvo, kushanda zvakanaka kwewelding yechubhu kunobvumira vagadziri kugadzira nekukurumidza huwandu hwakawanda hwemapaipi esimbi anotenderera kuti agutse kudiwa kuri kukura kwemusika.

Kusakwana Kwechigadzirwa

Maitiro aya anoda vashandi vane hunyanzvi uye kutonga kwakanyatsojeka kwezviyero zvewelding kudzivirira zvikanganiso zvakaita sekunge maburi kana kusabatanidzwa. Matambudziko aya anogona kukanganisa kunaka kwechigadzirwa chekupedzisira uye kukonzera njodzi dzekuchengetedza.

Pamusoro pezvo, tembiricha yakakwira yekuwelda kwearc inogona kukonzera kusasimba kwezvinhu, izvo zvinogona kukanganisa mashandiro epaipi kwenguva refu.

Mibvunzo Inowanzo bvunzwa

Mubvunzo 1: Chii chinonzi arc welding?

Kubatanidza simbi nearc inzira inoshandisa tembiricha yakakwira inogadzirwa nearc yemagetsi kuti inyungudise uye isanganise machira esimbi pamwe chete. Pamapaipi akasungirirwa nespiral, nzira iyi yakakosha pakugadzira kubatana kwakasimba pakati pemapaipi, izvo zvakakosha pakushanda uye hupenyu hwepombi.

Mubvunzo wechipiri: Sei kusanganisa arc kuchikosha pamapaipi egasi rechisikigo?

Mapaipi egasi rechisikigo anofanira kuzadzisa mitemo yakasimba yekuchengetedza uye kuvimbika. Maitiro ekusanganisa arc anoita kuti majoini eweld agone kumira kumanikidzwa kwakanyanya uye kuramba ngura, zvichiita kuti ive yakakodzera kutakura gasi rechisikigo munzvimbo refu.

Mubvunzo 3: Kambani yenyu iri kupi?

Fekitori yedu iri muCangzhou, Hebei Province, nzvimbo inozivikanwa nesimba rayo remaindasitiri. Kambani yedu yakavambwa muna 1993 uye yakakura zvakanyanya kusvika yasvika pakukura kwenzvimbo inosvika 350,000 square metres uye inoshandisa vashandi vakazvipira vanosvika 680.

Q4: Unyanzvi hwako hwekugadzira hupi?

Tinodada nekugadzira matani 400,000 emapaipi esimbi anotenderera pagore. Huwandu uhwu hunoshamisa hwekugadzira humbowo hwekuzvipira kwedu kune mhando uye kushanda zvakanaka mukugadzira kwedu.
