Umbhobho wentsimbi yodonga olungqingqwa ubhekiselele kumbhobho wedayamitha kunye nomlinganiselo wobunzima bodonga obungaphantsi kwama-20. Umahluko omkhulu phakathi kombhobho ongqindilili wodonga lwentsimbi kunye nombhobho obhityileyo wodonga lwentsimbi ngumbhobho wodonga, ngokubanzi, zizotywa iteknoloji yentsimbi ebhityileyo, kwaye ngokubanzi. ukusetyenziswa kweteknoloji yombhobho wentsimbi eshushu-engqingqwa, ukuba isetyenziselwa ukwahlula phakathi kweeyunithi zokulinganisa, ngoko, ngokubanzi, ubukhulu bodonga / ububanzi obulingana no-0.02 bubungqingqwa kwaye bubhityile, umbhobho wentsimbi, ubukhulu bodonga / ububanzi ngaphantsi. ngaphezu kwe-0.02 umbhobho wentsimbi obhityileyo, umbhobho wentsimbi ongqindilili wodonga mkhulu kuneenjongo, intsimbi ecekethekileyo yenjongo yombhobho.Intsimbi enezindonga ezininzi isetyenziswe kwindawo engenanto.Uxinzelelo kunye nejelo elibalulekileyo ekufuneka lisetyenziswe.

Intsimbi enodonga olungqingqwa isetyenziswa ikakhulu kubunjineli bamanzi, kushishino lwepetrochemical, ishishini lemichiza, ishishini lamandla, ukunkcenkceshela kwezolimo, ulwakhiwo lwasezidolophini.Ukuhanjiswa kolwelo: unikezelo lwamanzi kunye nokuhanjiswa kwamanzi.Ukuthutha igesi: igesi, umphunga, igesi yepetroleum engamanzi.Ngeenjongo zesakhiwo: njengombhobho wokufunxa iibhulorho;iidokhi, iindlela, izakhiwo kunye nezinye izakhiwo ityhubhu.

Isitshixo somgangatho wombhobho wentsimbi eludongeni olungqingqwa kufuneka ube ubukhulu obufanayo, umbhobho ongqingqwa wentsimbi ongqindilili wodonga alulawulwa ngokuthe ngqo kumgangatho kunye nokuba luncedo kombhobho wentsimbi, umbhobho wentsimbi ongqindilili, umbhobho omkhulu wentsimbi onomthungo wokusetyenziswa ngokubanzi kwiindidi ezahlukeneyo. wokucutshungulwa, ukusetyenzwa kodonga olungqingqwa, umbhobho wentsimbi ongqindilili ongqindilili wodonga uya kuchaphazela ngokuthe ngqo umgangatho wamacandelo agqityiweyo, udonga lombhobho wentsimbi olungqingqwa alulawulwa, umgangatho uwonke wentsimbi awungqongqo.

Welding umbhobho yentsimbi angqindilili-engqingqwa kuqala ioli ecocekileyo, ipeyinti, amanzi, umhlwa, njl, ngoko udonga groove, wavula inani elikhulu eshinyeneyo, ubhityile ukuvula inani elincinane (engile grinder), ngoko ke ukuba phezu umsantsa imveliso. , intonga okanye ucingo ububanzi ngokuqhelekileyo 1 - 1.5 amaxesha, ukuba awuqapheli i-groove yavulwa amagama ambalwa anokufaneleka ukuba ahlale encinci.Tack welding ubuncinane ngentsimbi yesithathu, intsimbi yesine jikelele umsebenzi olungileyo.Ixesha le-welding kufuneka libe sisiqingatha kunye nesiqingatha, ukuqala ukusuka kwindawo ephantsi, ngokukhethekileyo ngaphezu kweesentimitha okanye kunjalo, kuhle kakhulu ukusuka kwisihlanganisi esichaseneyo.Ukuba umbhobho udonga ubukhulu, kufuneka umaleko, ubuncinane ezimbini umaleko, umaleko wokuqala wesangqa de bagqibe welding unako weld umgangatho wesibini.

Malunga ne-Thick-endongaumbhobho wentsimbi ongenamthungo

Umbhobho wentsimbi ongenamthungo ongqindilili luhlobo lwecandelo elinqamlezileyo, akukho mithungo ejikeleze ibha ende yentsimbi.Inxalenye yentsimbi yentsimbi enenani elikhulu leendlela ezisetyenziselwa ukuhambisa ulwelo, njengeoyile yothumelo, igesi, igesi, amanzi kunye nezinye izinto eziqinileyo, imibhobho njalo njalo.Umbhobho wentsimbi kunye nentsimbi eqinileyo yebar ejikelezayo, njl.

xa kuthelekiswa namandla okugoba afanayo ekugobeni, ukukhanya, yintsimbi yezoqoqosho enqamlezileyo, esetyenziswa ngokubanzi ekwenzeni iinxalenye zesakhiwo kunye namalungu omatshini, anjengombhobho wokubhobhoza, iishafti zokuqhuba iimoto, iinqwelomoya zebhayisekile kunye nokwakhiwa kusetyenziswa isikafula sentsimbi.Umsesane kunye neengxenye zokuvelisa umbhobho wensimbi, unokuphucula ukusetyenziswa kwezinto, ukwenza lula inkqubo yokuvelisa, izinto zokulondoloza kunye nokucubungula iiyure zomntu, ezifana nezangqa zokuthwala, i-jack sets, njl., sele isetyenziswe ngokubanzi ukwenza intsimbi.Intsimbi okanye iintlobo ngeentlobo zezixhobo eziqhelekileyo eziyimfuneko, umphanda, umphanda kunye nezinye iintsimbi eziza kwenziwa.Ngokumila kwecandelo lombhobho unokwahlulwa ube ityhubhu kunye nemibhobho emile.Ukususela kwi-circumference yeemeko ezifanayo, indawo ephezulu yesangqa, kunye nombhobho ojikelezayo unokuthwala amanzi amaninzi.Ukongezelela, i-ring cross-section yokumelana noxinzelelo lwe-radial yangaphakathi okanye yangaphandle, amandla angaphezulu ngokulinganayo, ngoko ubuninzi bombhobho ngumbhobho.
