Imimiselo yemibhobho yentsimbi enodonga olungqingqwa kubunjineli: imimiselo ehambelanayo kunye nemimiselo eyahlukeneyo yokhetho lokwenene kunye nokusetyenziswa kofakelo lwemibhobho engqingqwa. Xa imibhobho yentsimbi enodonga olungqingqwa kunye nokufakelwa kwemibhobho engqindilili-engqingqwa ikhethiweyo okanye isetyenzisiwe, kufuneka kuqala ilandele imimiselo efanelekileyo kunye nemimiselo eyahlukeneyo kwiinkcukacha, ngakumbi kwimibhobho ehambisa imidiya yolwelo eyingozi kakhulu okanye eyingozi kakhulu, imidiya enokutsha, kunye noxinzelelo oluphezulu. iigesi. Ngaphantsi kwesi sizathu, uhlobo lwezixhobo zombhobho lunqunywe ngokukodwa ngokusekelwe kwinjongo kunye neemeko zokusetyenziswa (uxinzelelo, ubushushu, i-fluid medium).

Iingxaki kwimigangatho yokukhetha imibhobho yentsimbi enodonga olungqingqwa:
1. Iqulunqwe ukusuka kwinkqubo eqhelekileyo. Ukukhethwa kwiprojekthi, kukho imigangatho yemibhobho, kodwa akukho migangatho ehambelanayo ye-forgings okanye i-castings. Inyaniso kukuba imigangatho yokufakelwa kwemibhobho kunye ne-forgings iboleka imigangatho ye-forging yemikhumbi yoxinzelelo, ngaphandle kokuqwalasela ukungafani phakathi kwezi zibini, ezifana ne-welding, ukuhlolwa kwefilimu kunye neminye imimiselo.
2. Imigangatho yokufakelwa kwemibhobho iyahluka kakhulu, kwaye umxholo awunakho ukuhambelana kunye nokucwangciswa kwenkqubo, okubangelwa ukuchasana koqhagamshelwano, kunye nokubangela ukuphazamiseka ekusebenziseni.
3. Akukho mgangatho wokuvavanya uhlobo lokufakelwa kwemibhobho. Kuphela i-GB12459 kunye nemigangatho ye-GB13401 ichaza ukubalwa koxinzelelo lovavanyo oluqhumayo lwentsimbi ye-butt-welded i-fittings engenamthungo yombhobho kunye ne-steel plate butt-welded pipe fittings. Azikho ezinye iintlobo zemigangatho yovavanyo okanye imigangatho yokuphunyezwa ukuqinisekisa ukuveliswa kwezixhobo zombhobho. Ifomula yobunzima bombhobho otyebileyo ongenamthungo: [(ubunzima bodonga lwangaphandle)*ubukhulu bodonga]*0.02466=kg/imitha (ubunzima ngemitha).

Ukumiselwa kwenqanaba lamandla emibhobho yentsimbi enodonga olungqingqwa:
I-1) Izixhobo zombhobho ezibonisa ibakala lazo okanye zichaze imilinganiselo yoxinzelelo-iqondo lokushisa kuxinzelelo oluncinci kufuneka lusebenzise umlinganiselo weqondo lokushisa elichazwe kumgangatho njengesiseko sokusetyenziswa kwazo, njenge-GB / T17185;
2) Ukulungiswa kombhobho ochaza kuphela ubukhulu obucacileyo bombhobho othe ngqo oqhagamshelwe kubo kumgangatho, ukulinganisa kwabo okusebenzayo koxinzelelo lobushushu kufuneka kumiselwe ngokwenqanaba lombhobho lokulinganisa elichazwe kumgangatho, njenge-GB14383 ~ GB14626.
3) Ukufakelwa kwemibhobho echaza kuphela imilinganiselo yangaphandle kumgangatho, njenge-GB12459 kunye ne-GB13401, amandla abo okunyamezela kufuneka agqitywe ngeemvavanyo zokuqinisekisa.
I-4) Kwabanye, i-benchmark yokusetyenziswa kufuneka igqitywe ngokuyila uxinzelelo okanye uhlalutyo lokuhlalutya ngemimiselo efanelekileyo. Ukongezelela, umgangatho wamandla wokufakelwa kombhobho akufanele ube ngaphantsi koxinzelelo phantsi kweemeko ezinzima zokusebenza apho yonke inkqubo yombhobho ingadibana nayo ngexesha lokusebenza.
