Tekinoroji yeUnyanzvi hweKuputira Tube

Tekinoroji yeWeld yeProfessional Tube Mufananidzo Wakaratidzwa

Tsananguro pfupi:

Chinonyanya kukosha mukuvandudzwa uku itekinoroji yedu yepamusoro yeSubmerged Arc Welding (SAW), nzira inonyanya kufarirwa yemapaipi akasungirirwa nesimbi. Tekinoroji iyi inoita kuti ive chaiyo, inogara kwenguva refu uye inoshanda, zvichiita kuti ive yakakodzera kumaindasitiri anovimba nemapaipi akasungirirwa emhando yepamusoro.

Kubatsira Kwekambani

Iri pakati peguta reCangzhou, Hebei Province, kambani iyi yave iri kutungamira mukugadzira mapaipi akasungirirwa kubva payakatangwa muna 1993. Chivako ichi chine nzvimbo inosvika 350,000 square metres uye chine michina yepamusoro uye tekinoroji yekugadzira zvigadzirwa zvepamusoro zvinosangana nezvinodiwa pasi rose. Nehupfumi hwese hweRMB 680 miriyoni uye vashandi vane hunyanzvi 680, kambani iyi yakazvipira kuita basa rakanaka mune zvese zvinoitwa.

Nhanganyaya yeChigadzirwa

Tinounza tekinoroji yedu yepamusoro-soro yekuwedera mapaipi, yakagadzirirwa zvakananga kusangana nezvinodiwa zvemapaipi egasi rechisikigo ekuwedera arc. Chinonyanya kukosha mukuvandudzwa uku tekinoroji yedu yepamusoro yeSubmerged Arc Welding (SAW), nzira inofarirwa yemapaipi akawedera anotenderera. Iyi tekinoroji inovimbisa kurongeka, kugara kwenguva refu uye kushanda zvakanaka, zvichiita kuti ive yakakodzera kumaindasitiri anovimba nemapaipi akawedera emhando yepamusoro.

Nyanzvi yedukusona mapaipiTekinoroji haingogadzirisi chete kunaka kwemapaipi egasi, asiwo inovandudza maitiro ekunamira, inopfupisa nguva yekugadzira uye inoderedza mari. Tinonzwisisa kukosha kwemasisitimu emapaipi egasi, uye kuzvipira kwedu kune mhando kunoita kuti zvigadzirwa zvedu zvigone kumira zvinodiwa zvakanyanya zvemashandisirwo azvo.

Sezvatinoramba tichivandudza tekinoroji yekuwelda, tinokukokai kuti muone kuvimbika uye kushanda kwetekinoroji yedu yehunyanzvi yekuwelda mapaipi. Tivimbei kuti tikupei mapaipi emhando yepamusoro anosangana nezvamunoda, zvichitsigirwa nehunyanzvi hwemakumi emakore uye kuzvipira kugutsa vatengi.

Kubatsira Kwechigadzirwa

1. Chimwe chezvakanakira zvikuru zvekushandisa welding ye arc yakanyudzwa mumvura kusanganisa mapaipi egasi rechisikigo kugona kwayo kugadzira zvinhu zvemhando yepamusoroweld yechubhuisina zvikanganiso zvakawanda. Maitiro ekunyudza arc akadzika pasi anogonesa kupinda kwakadzika uye nzvimbo dzakatsetseka, izvo zvakakosha pakuona kuti mapaipi egasi rechisikigo akasimba.

2. Kugadzira otomatiki kwe welding ye arc inonyudzwa mumvura kunogona kuwedzera kugona uye kuderedza mari yevashandi nenguva yebasa.

Kushaikwa kwechigadzirwa

1. Chimwe chinhu chakaipa ndechekuti mitengo yekutanga yakakwira, iyo inogona kunge yakakwira nekuda kwekudiwa kwemidziyo yakasarudzika uye vashandisi vane hunyanzvi.

2. Maitiro acho haana kuchinjika semamwe maitiro ekunamira, zvichiita kuti asakodzere kushandiswa pakugadzira madziro akaomarara kana zvinhu zvine madziro matete.

3. Kuganhurirwa uku kunogona kukonzera matambudziko mune mamwe mashandisirwo, zvichikonzera kuti purogiramu irebe.

Mibvunzo Inowanzo bvunzwa

Mubvunzo 1. Chii chinonzi Submerged Arc Welding (SAW)?

SAW inzira yekusanganisa inoshandisa electrode inopihwa nguva dzose uye jira regranular fusible flux kudzivirira weld kubva mukusvibiswa. Nzira iyi inoshanda zvakanyanya pazvinhu zvakakora uye yakakodzera mapaipi egasi rechisikigo.

Mubvunzo wechipiri. Sei SAW ichinyanya kufarirwa pamapombi akasungirirwa nesimbi dzakatenderedzwa?

Tekinoroji yeSAW inoita kuti pave nekupinda kwakadzama uye pamusoro payo pave pakachena, izvo zvakakosha pakuchengetedza chimiro chayo.pombi yakasungirirwa yakatendererainoshandiswa mukushandiswa kwemhepo ine simba guru sekufambisa gasi rechisikigo.

Mubvunzo 3. Ndezvipi zvakanakira kushandisa tekinoroji yehunyanzvi yekuwedera mapaipi?

Matekiniki ekugadzira machubhu ane hunyanzvi anobatsira kuti zvinhu zvirambe zvakanaka, anoderedza njodzi yekukanganisika uye anovandudza mashandiro ezvigadzirwa zvakasungirirwa, izvo zvakakosha muindasitiri yakakosha pakuchengetedza.

Mubvunzo we4. Kambani yenyu inovimbisa sei mhando yemaitiro ekuwelda?

Kambani yedu inotevedzera mitemo yakasimba yekudzora mhando uye inoshandisa matekiniki ane hunyanzvi akadzidziswa matekiniki matsva ekunamira, kusanganisira SAW, kuti ive nechokwadi chekuti chigadzirwa chega chega chinosangana nemitemo yakasimba yekuchengetedzwa uye mashandiro.
