Walƙiya kai tsaye (DC) waldi da walƙiya na yanzu (AC) ana amfani da su da yawahanyoyin walda, kuma kowannensu yana da halayensa. A cikin wannan labarin, za mu bincika abin da suke da bambance-bambance tsakanin DC waldi da AC waldi a fagenjuriya waldi, kuma wanne walda ne ya fi fa'ida? Wannan zai taimaka muku zaɓi tsakanin su biyun.
Ka'idojin Aiki:
MFDC/Inverter Welding Machine:
Na farko,mataki ukuWutar lantarki ta AC ta wuce ta masu gyara don tacewa.
Na biyu,IGBTmasu sauyawa suna canza halin yanzu zuwa matsakaicin matsakaicin 1000 Hz kuma suna aika shi zuwa gawutar lantarki ta walda.
A ƙarshe, diodes masu gyara ƙarfi mai ƙarfi suna fitar da walƙiyar halin yanzu a matsayin barga kai tsaye (DC).
AC walda Machine:
Shigar da wutar lantarki shine AC, wanda bayan ya wuce ta hanyar wutar lantarki, yana shiga babban kewayawa da kewaye.
Gidan wuta yana sauko da babban ƙarfin wutar lantarki zuwa AC mai ƙarancin wutar lantarki wanda ya dace da walda. AC halin yanzu musanya tsakanin tabbatacce da korau, samar da zafi kamar yadda ya wuce ta cikin walda sanda da workpiece, game da shi narke da walda abu da kuma cimma waldi.
Menene bambance-bambance tsakanin walda DC da waldi na AC?
Kwanciyar hankali
Welding DC yana ɗaya daga cikin samfuran walda masu ƙarfi da aka sani na duniya tare da kwanciyar hankali mai ƙarfi. Siffofin tsarin walda suna da abokantaka, ADAPTS na biyu na yanzu zuwa kewayo mai faɗi, kuma da gaske suna kiyaye halin yanzu, wanda ke da fa'idar aikace-aikacen da ya fi ƙarfin walƙiya AC.
Ana daidaita wutar walda ta DC a cikin adadin sau 1000 a cikin daƙiƙa guda, wanda ya kai daidaito na millisecond, wanda ya fi sau 20 sama da daidaiton na'urorin walda na AC na gargajiya.
DC waldi ba ya shafar siffar da kayan aikin aikin, yana kawar da asarar inductance. Injin walda AC yana da sauƙin waldawa ko rashin ƙarfi saboda canje-canje a cikin sigar kayan aikin.
Weld Splash
Wutar wutar lantarki ta DC tana fitar da mafi ƙanƙanta nau'in igiyar ruwa don gujewa kololuwar firgita a halin yanzu da rage fantsama yayin walda. Amma walda AC a cikin tsarin waldawa zai haifar da yawan spatter, yana shafar ingancin samfuran walda.
Ingantacciyar walda
Ma'aunin wutar lantarki na injin walda na DC ya fi kashi 98%, kuma ma'aunin wutar lantarki na injin walda AC ya kai kusan kashi 60%, wanda ke nuni da cewa ingancin walda na DC ya fi AC girma.
Farashin
Saboda darajar farko na DC waldi halin yanzu yana ƙaruwa sosai, ainihin lokacin walda yana raguwa da fiye da 20%, kuma ana adana farashin lokacin sosai.
Koyaya, a cikin farashin injin walda, injin walda AC ya fi rinjaye, kuma farashinsa yana iya zama na gaba ɗaya ko ma ƙasa da na'urar DC. Idan kuna da ƙarancin kasafin kuɗi don siyan injin walda, to injin AC shima zaɓi ne mai kyau.
Kare Makamashi
Abubuwan da ake buƙata don samar da wutar lantarki na masana'anta ba su da ƙasa, kusan 2/3 na walda AC, ko da ƙarfin wutar lantarki yana canzawa, walda DC na iya sarrafa daidaitaccen walda na halin yanzu. Don haka, ana rage yawan amfani da injin walda na DC sosai, kuma ana samun sama da 40% ceton makamashi.
Kare Muhalli
Walda DC hanya ce ta koren walda wacce ke kawar da gurɓataccen wutar lantarki, baya buƙatar wutar lantarki daban, kuma ana iya amfani da ita tare da tsarin sarrafa walda na robot. Walda AC yana da babban tasiri akan grid ɗin wutar lantarki, kuma yana da sauƙin gurɓata wutar lantarki.
Takaitawa
A taƙaice, waldar DC ta fi walƙar AC ta fuskoki da dama. Idan kuna da isasshen kasafin kuɗi, to dole ne ku zaɓi waldi na DC. Bugu da kari, idan kuna buƙatar walda samfuran tare da buƙatu masu inganci, injin DC kuma shine mafi kyawun zaɓinku.
