Indlela ukukhetha Ungqameko ubukhulu ekunene

Imilo uphawu ngentsimbi kunye neempawu zayo amandla niyenze ukusetyenziswa mlonyeni kumacandelo ahlukeneyo ezoqoqosho. Kuxhomekeka isicelo, khetha iintlobo ngeentlobo kunye ubukhulu imivalo mzila. Asetyenziswe ngayo zokuhlala kunye nolwakhiwo-mveliso, oomatshini, imoto kaloliwe, ngexesha ukulungiswa ezahlukeneyo ukuvelisa kweeshelfu kunye imigangatho unyanzeliso, nengcinga intengiso yangaphandle ukuba ezithambekileyo.

Channel aza kusetyenziswa isakhi ekwenziweni milenge, iibhulorho, iipayiloni aphezulu ombane, rigs ioli, nasiphi na isakhelo isakhiwo kunye ukuvala unxibelelwano. Naphi na kudlala izinto ezibuhlungu indima ebalulekileyo namandla xa ubunzima iphantsi kakhulu.

iintlobo Ungqameko

The basic izinto lokuvelisa ezi mveliso - zentsimbi (carbon kwesakhiwo, ingxubevange ephantsi, shushu liqengqiwe nengqele liqengqiwe). Ukwahlula eshushu (ngokuchanileyo eziqhelekileyo eyonyukileyo nomnombo) kunye kwijelo egobile.

Hot-liqengqiwe intsimbi eqhelekileyo iishelfu parallel, kodwa basenokuba kuyilwa kunye ethambekeni (hayi ngaphezulu kwe-10%). Imilinganiselo Ungqameko injongo jikelele okanye injongo ekhethekileyo (ngakumbi, kuba Umatshini ohambayo) yahluke ububanzi nobude ezishelifini (dimensions zinikwe CCITT 8240-89, kunye 19425-74). Yahlula GOST ikhona iinkangeleko zokwakha imoto (GOST 5267.1-90).

imveliso liphindwe abangaboni ukwahlula yi ajikelezayo yangaphakathi kwikona ezishelifini kwaye ngokulinganayo olungalinganiyo. Kuye ubukhulu channel (GOST 8278-75) ubude kunye neemitha ezingama-12, kodwa isicelo kunye nokuvelisa profiles elide.

Ubukhulu Ungqameko

Xa kukhethwa inkangeleko sikhokelwa ezingundoqo parameters zayo leyo iza kucacisa ukuphakama, ububanzi kunye esisangqa Ebubanzini, udonga ubukhulu, radius yangaphakathi esime okanye ukuqoqa ezishelifini.

Kukho iintlobo ezininzi, ubukhulu kunye neempawu kulawulwa nemigangatho. Ngoko ke, umgangatho imveliso kulula ukuba ukujonga ngokuthelekisa Ubukhulu kanye U-amacandelo elixelwe GOST.

ubuqili nokufaka

Xa kumakishwa ubukhulu iprofayile idla kubonisiwe ngeesentimitha oonobumba lokukhetha parameter nganye. Umzekelo, channel 8P, imilinganiso zazo umgangatho, uthi ukuphakama kwayo - iisentimitha-8, kunye ezishelifini ngaxeshanye. Hi ndlela leyi, iimveliso kunye nobukhulu oluqhelekileyo advantageously kusetyenziswa zokomeleza izakhiwo, njengoko ofunwa kunye ngaphandle iingxaki, kwaye ezenziwa elungeleleneyo yaye ezolile carbon ngentsimbi.

Ukulungiselela ukuncitshiswa lokwakha umjelo metal naye wasebenzisa 12P, leyo uneempawu amandla ephakamileyo. Kodwa umthengisi Phezulu iprofayile eshushu-16P.

Okukodwa metal yesicelo kusoloko kuxhomekeke kwibakala sentsimbi, esetyenziswa imveliso yawo. Umzekelo, ukuba isicelo engontsini yasentla, apho amaqondo aphantsi ze eqhelekileyo yosetyenziso eyenziwe ezisezantsi-carbon 09G2S zokwakha. Oku kungenxa yokuba amandla aphezulu ebangeni ngomatshini enikwe ngentsimbi, lula welding, ukuxhathisa amaqondo aphantsi.
