① imeko yonikezelo
Ibhekisela kwimeko yokuguqulwa kokugqibela kweplastiki okanye unyango lokugqibela lobushushu lwemveliso enikezelweyo. Ngokuqhelekileyo, ukuqengqeleka okutshisayo okanye ukutsalwa okubandayo (ukuqengqeleka) urhulumente okanye imeko yokuvelisa: imeko yonyango lobushushu lokunikezelwa emva kokunyanga ubushushu, okanye umlilo oqhelekileyo (oqhelekileyo), ukulungiswa komgangatho, isisombululo esiqinileyo, i-annealing state ngokwecandelo lonyango lokushisa.Xa uyala, isimo sokuhanjiswa siya kuboniswa kwisivumelwano.
② ihanjiswa ngobunzima bokwenene okanye ubunzima bethiyori
Obona bunzima-Ekuhanjisweni, ubunzima bemveliso buhanjiswa ngobunzima (ubunzima) ubunzima;
Ubunzima bethiyori-Ubunzima bemveliso bubunzima obubalwe ukusuka kubukhulu obuqhelekileyo bentsimbi.Ifomula yokubala ilandelayo (efunekayo ngokwexabiso lethiyori, iya kuboniswa kwinkontileka): ubunzima bethiyori ngemitha (ubuninzi bentsimbi). yi-7.85 kg/dms3) ifomula yokubala:
Uhlobo w = (DS) S: ubunzima bethiyori ye-T enye ipayipi yensimbi ngemitha, kg / m;Idayamitha yangaphandle yegama lombhobho we-D-steel, m: s ubukhulu bodonga lwegama lombhobho wentsimbi enye, m.
③ isiqinisekiso iimeko
Ngokomgangatho wangoku wosuku oluchaziweyo lokuhlolwa kunye nokuqinisekisa ukuthotyelwa komgangatho, obizwa ngokuba yimiqathango yesiqinisekiso.Iimeko zesiqinisekiso nazo zahlulwe zibe:
A. Iimeko zesiqinisekiso esisisiseko (ekwaziwa ngokuba yimiqathango yesiqinisekiso esisinyanzelo).Nokuba ibonisiwe kwikhontrakthi okanye ayibonisiwe.Yonke imigangatho yobugcisa iya kubaleka ukuhlolwa, kwaye iqinisekise ukuba iziphumo zohlolo ziyahlangabezana nemimiselo esemgangathweni.Efana nokwakheka kweekhemikhali, oomatshini. iipropathi, ukuphambuka kobungakanani, umgangatho womgangatho kunye nokufumanisa impazamo, uvavanyo lwe-hydraulic okanye fan pressure okanye ukwandiswa kwe-1 1 kunye nezinye iimvavanyo zenkqubo yokusebenza, zifunwa iimeko.
B. Imiqathango yesiqinisekiso seSivumelwano: Ngaphandle kweemeko zesiqinisekiso esisisiseko kumgangatho, kukho ” uthethathethwano phakathi kwamaqela amabini ngokweemfuno zomfaki-sicelo. Kwaye uyiphawule kwikhontrakthi?Ikowuti;okanye ” xa umthengi eyifuna.Funa…, kufuneka iboniswe kwikhontrakthi “;abanye abathengi, iimfuno ezisisiseko zewaranti ezifana nokubunjwa, iimpawu zomatshini, ukutenxa ubungakanani, njl. njl.) okanye izinto zokuhlola ezongezelelweyo (ezifana ne-ellipticity yentsimbi yombhobho, ubukhulu bodonga olungalinganiyo). Le migaqo ingentla kunye neemfuno, xa u-odola, ukubonelela kunye nokufunwa kwamaqela. iya kuthetha-thethana, isayine isivumelwano sobuxhakaxhaka bokubonelela kwaye ibonise kwikhontrakthi.Ngoko ke, le miqathango ikwabizwa ngokuba yimiqathango yesiqinisekiso sesivumelwano.Iimveliso ezinemiqathango yokuqinisekisa isivumelwano, ixabiso kufuneka linyuswe.
④ bhala imiyalelo okanye izimvo
"Ibhetshi" kumgangatho ubhekiselele kwiyunithi yokuhlola, oko kukuthi ibhetshi yokuhlola.Ukuba iqela leqela lokuhambisa, elibizwa ngokuba yibhetshi yokuhambisa.Xa ibhetshi yokuhambisa ikhulu, ibhetshi nganye yokuhambisa ingabandakanya iibhetshi ezininzi zokuhlola: xa ibhetshi yokuhambisa ihambisa. incinci, ibhetshi yokuhlola inokwahlulwa ibe ziibhetshi ezininzi zokuhanjiswa.Ukwakheka kwe "ibhetshi" ngokuqhelekileyo kunamalungiselelo alandelayo (jonga imigangatho efanelekileyo):
A. Ibhetshi nganye iya kuqulunqwa ngemibhobho yentsimbi kunye nenombolo ye-brand efanayo (ibakala lentsimbi), inombolo yesithando somlilo (itanki) enye okanye inombolo yesithando somlilo sikanina, ukucaciswa okufanayo kunye nenkqubo efanayo yonyango lobushushu (amaxesha eziko).
B. Kwimibhobho yesakhiwo se-carbon steel ephezulu kunye nemibhobho yamanzi, iziko ezahlukeneyo (iitanki) zinokuba nenombolo ye-brand efanayo, inkcazo efanayo kunye nenkqubo yokushisa ukushisa okufanayo (amaxesha esithandweni).Ukuqulunqwa kombhobho wensimbi.
C. Ibhetshi nganye yombhobho wentsimbi edityanisiweyo iya kuqulunqwa ngombhobho wentsimbi kunye nenqanaba elifanayo (ibakala lentsimbi) kunye neenkcukacha ezifanayo.
⑤ umgangatho wentsimbi kunye nentsimbi ephezulu
Kwimigangatho ye-GB / T699-1999 kunye ne-GB / T3077-1999, i-brand yayo ibuyele nge-"A", yentsimbi yezinga eliphezulu, ngaphandle koko insimbi ephezulu.
A. Nciphisa uluhlu lomxholo wecandelo:
B. Ukunciphisa umxholo wezinto ezinobungozi (ezifana nokuhamba, i-phosphorus kunye nentsimbi):
