Chitsulo cha Erw Carbon

Chitoliro chachitsulo choswedwa cha ERW

Kodi chitoliro chachitsulo cha ERW n'chiyani?
Kuwotcherera kwa ERWChitoliro chachitsulo choswedwa cha ERW: ndiko kuti, chitoliro cholumikizira magetsi cholimba cha msoko wowongoka, ndipo cholumikiziracho ndi cholumikizira cha longitudinal weld. Chitoliro chachitsulo cha ERW chimagwiritsa ntchito cholumikizira chotentha ngati zinthu zopangira, ndipo chimapindika, kupangidwa mosalekeza, kuwotcherera, kutentha, kukula, kuwongola, kudula ndi njira zina. Pa nthawi yowotcherera chitoliro cha ERW, mphamvu yamagetsi imapanga kutentha ikadutsa pamwamba pa malo olumikizirana. Imatenthetsa m'mbali ziwiri za chitsulo mpaka kufika poti m'mbali mwake mutha kupanga mgwirizano. Nthawi yomweyo, pansi pa mphamvu yophatikizana, m'mbali mwa chubucho chitsulo chopanda kanthu chimasungunuka ndikufinyidwa pamodzi.
Chitoliro cha ERW ndi chidule cha chitoliro chachitsulo chosungunuka cholimba, pomwe chitoliro cha HFW chimayimira chitoliro chachitsulo chosungunuka chosungunuka pafupipafupi. Chitolirocho chimapangidwa ndi zitsulo zozungulira, ndipo zosungunula zimakhala zofanana ndi chitolirocho. Ndi chimodzi mwa zida zomwe zimagwiritsidwa ntchito kwambiri pa ntchito zaulimi, mafakitale, ndi zomangamanga.
Njira yopangira mapaipi achitsulo a ERW imaphatikizapo HFW. Kuwotcherera kwa ERW kumaphatikizapo kuwotcherera kwa ma frequency otsika, apakati, ndi okwera, pomwe HFW ndi yoyenera kwambiri kuwotcherera kwa ma frequency apamwamba.
Chitoliro cha ERW: chitoliro choponderezedwa cholimbaM'mimba mwake wakunja (m'mimba mwake wakunja): 10.3mm-609mm, makulidwe: 0.5-20mm kapena osinthidwa. Pa mapaipi akuluakulu, kuwotcherera kwa arc pansi pa madzi kudzagwiritsidwa ntchito popanga.

 

 

Chitoliro cha HFW: chitoliro cholumikizidwa pafupipafupi kwambiri

Kodi chitoliro chachitsulo cha HFW n'chiyani?
Tiyenera kudziwa kuti chitoliro cha HFW ndi mtundu waChitoliro cha ERW.
Chitoliro chachitsulo cholumikizidwa ndi ma frequency ambiri (HFW) chimatanthauza chitoliro cha ERW chokhala ndi ma current current ofanana kapena ochulukirapo kuposa 70kHZ. Kudzera mu kukana kwa ma frequency ambiri, kutentha komwe kumachitika pokhudzana ndi chinthucho kumapangitsa kuti pamwamba pa chinthucho patenthedwe kukhala pulasitiki, kenako kupanga kumachitika kapena ayi kuti chitsulo chisakanizidwe. HFW ndi mphamvu yolimba yolimbana ndi kutentha. Pamene ma frequency ambiri amadutsa kudzera mu kondakitala yachitsulo, zotsatira ziwiri zapadera, zotsatira za khungu ndi zotsatira za kuyandikira, zidzachitika. Njira ya HFW imagwiritsa ntchito zotsatira za khungu kuti iyang'ane pamwamba pa chinthu chachitsulo ndi zotsatira za kuyandikira kuti ilamulire malo ndi mphamvu ya njira yoyendera ma frequency ambiri. Chifukwa cha liwiro lalikulu, m'mphepete mwa mbale zolumikizirana zimatha kutenthedwa ndikusungunuka pagombe, kenako nkutulutsidwa kudzera mu njira ya butt.
Tiyenera kudziwa kuti chubu cha HFW ndi mtundu wa chubu cha ERW.

Kuwotcherera kwapamwamba kwambiri (HFW) ndi mphamvu yolimba yolimbana ndi kutentha. Kudzera mu kukana kuwotcherera kwamphamvu kwambiri, kutentha kumapangidwa mu chinthu chokhudzana, kotero kuti pamwamba pa chinthucho chimatenthedwa kukhala pulasitiki, kenako chimapangidwa kapena sichinapangidwe kuti chigwirizane ndi chitsulo.

Chitoliro cha Chitsulo cha Hfw

Kugwiritsa ntchito ndi ubwino wa chitoliro chachitsulo cha ERW
ERW imayimira kukana kuwotcherera, komwe kuli ndi mawonekedwe a kupanga bwino kwambiri, mtengo wotsika, kusunga zinthu, komanso automation yosavuta. Chifukwa chake, imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana amafakitale monga ndege, ndege, mphamvu, zamagetsi, magalimoto, ndi mafakitale opepuka, ndipo ndi imodzi mwa njira zofunika kwambiri zowotcherera.

Ubwino wa chubu cha HFW
Pa nthawi yothira zitsulo, mapaipi achitsulo a HFW safuna kuwonjezera chitsulo chodzaza. Chifukwa chake, liwiro la kuthira zitsulo limakhala lachangu ndipo mphamvu yopangira ndi yayikulu. Mapaipi a HFW amagwiritsidwa ntchito kwambiri ponyamula mafuta ndi gasi, mapaipi a zitsime zamafuta, nyumba zomangira, ndi mapaipi osiyanasiyana amakina. Komabe, ubwino wa mapaipi achitsulo a HFW umakhudzidwa ndi zinthu zosiyanasiyana monga zipangizo zopangira ndi njira zopangira. Ndipo kuwongolera khalidwe la kupanga kwakhala kovuta. Chifukwa chake njira yopangira ndi kuthira zitsulo ikufunikabe kukonzedwa nthawi zonse.

Kusiyana pakati pa ERW (straight seam resistance welding) ndi HFW (high-frequency welding) makamaka ndi mfundo yaikulu.
Kuwotcherera kokana, monga momwe dzinalo likusonyezera, ndi njira yowotcherera poika mphamvu kudzera mu ma electrode pambuyo poti weldment yaphatikizidwa, ndikugwiritsa ntchito kutentha kokana komwe kumapangidwa ndi mphamvu yomwe imadutsa pamwamba pa malo olumikizirana ndi madera oyandikana nawo. Kuwotcherera kokana: Pamene mphamvu yokana imadutsa kudzera mu kondakitala yachitsulo, zotsatira ziwiri zapadera zidzapangidwa: zotsatira za khungu ndi zotsatira za kuyandikira. Kuwotcherera kokana kumagwiritsa ntchito zotsatira ziwirizi kuwotcherera mapaipi achitsulo. Zotsatira ziwirizi ndiye maziko opangira kuwotcherera kokana kwachitsulo.
Kuwotcherera kwamphamvu kwambiri kumagwiritsa ntchito mphamvu ya khungu kuti ipangitse mphamvu ya mphamvu yamphamvu yamagetsi yamagetsi yamagetsi pamwamba pa chogwirira ntchito; ndipo imagwiritsa ntchito mphamvu yapafupi kuti ilamulire malo ndi kuchuluka kwa njira yoyendera mphamvu yamagetsi ...
