Ukusetyenziswa kweeflange kubunjineli bombhobho

I-welding ye-flanges enkulu iyinxalenye edibanisa iipayipi komnye nomnye, edibeneyo ekupheleni kombhobho, kwaye itywinwe nge-gasket phakathi kwabo.Ukuwelda kweeflange ezinkulu, ezaziwa ngokuba zii-welding flanges, zinemingxuma kwi-welding flange

Uxhulumaniso oluqinileyo luhlobo lwecandelo le-disc-shaped elifumaneka rhoqo kubunjineli bemibhobho.

Isantya esiphezulu sokubumba (i-150-200mm / s) siyafuneka kwi-welding yensimbi kunye ne-thermal conductivity enhle yeeflanges ezinkulu.Ngokubhekiselele kwintsimbi efanayo, kukho i-gradient enkulu yokushisa kwindawo ye-interface ngenxa yendalo ebandayo yokudibanisa

Kufuneka kwandiswe isantya sobumbi.Ukunyanzeliswa koxinzelelo lwe-Fu Fu ngokuqhelekileyo kuboniswa ngoxinzelelo kwindawo yeyunithi, oko kukuthi, amandla oxinzelelo lokubumba.Ubungakanani boxinzelelo lokubumba kufuneka buqinisekise ukuba isinyithi se-liquid ngaphakathi kwe-interface sinokukhutshwa

Ungena kwi-deformation ethile yeplastiki.

Ngenxa yomsebenzi wayo ogqwesileyo wokukhuthaza, iiflange ezinkulu zisetyenziswa ngokubanzi kwimichiza, ulwakhiwo, unikezelo lwamanzi, ukuhambisa amanzi, i-petroleum, amashishini alula kunye anzima, ifriji, ugutyulo, imibhobho yamanzi, amandla kunye namashishini okuvelisa.

Cheng.

Xa udibanisa ama-flanges amakhulu, ukuba i-top forging pressure incinci kakhulu, i-deformation ayinelanga kwaye amandla adibeneyo ayancipha;Ukuba i-top forging pressure yomelele kakhulu, i-deformation iya kuba nkulu kakhulu, kwaye i-crystal grain iya kugoba kwaye ibe nzima, eya kunciphisa ukuqina kwempembelelo yomdibaniso.

Isantya sokukhanya okuqaqambileyo kuya kubangela ukwanda kweqondo lobushushu, ngoko ke xa ukuwelda isinyithi kunye conductivity elungileyo thermal (ubhedu, ingxubevange aluminiyam), flanges ezikhethekileyo zentsimbi zifuna uxinzelelo olukhulu lokubumba (150-400Mpa).

Ukongeza kwiiparamitha zenkqubo engentla, ukushisa kwangaphambili kunye nexesha lokufudumala kufuneka kuthathelwe ingqalelo kwi-preheating i-welding spot parameters.Ukushisa kokushisa kwangaphambili kukhethwe ngokusekelwe kwi-workpiece cross-section kunye nomsebenzi wezinto eziphathekayo.Xa udiza intsimbi enekhabhoni ephantsi,

700-900 degrees.

Ngokuqhelekileyo, i-arc welding manual isetyenziselwa i-welding flanges enkulu, kunye nemigca ye-arc ye-welding engaqhelekanga kunye nokutshisa okulula kunye nokunyanzeliswa kwe-edge ye-lining edge, engenako ukupheliswa nangomatshini, okubangelwa ukubukeka okungahambi kakuhle;2. Ngenxa yokuba ngokuqhelekileyo luhlobo oluthile lwentsimbi

I-welding enkulu yangoku, ukulawulwa kakubi kwe-welding current, kunye nokuvela lula kwe-undercutting okanye i-welding engaphelelanga.Kwiiflange ezinkulu zeconvex, i-welding seam idinga ukucutshungulwa, ukuze kubekho intsimbi encinci efakwe phakathi kweringi kunye neflange.
