Umbhobho wentsimbi we-Q345B ongenamthungo ulungelelaniswe kwaye unzulu
Inkcazelo emfutshane:
Umbhobho wentsimbi ongenamthungo luhlobo lwentsimbi engqukuva, esisikwere kunye noxande enecandelo elinomgongxo kwaye akukho zidibaniselwano zijikeleze umbhobho wentsimbi ongenamthungo owenziwe ngentsimbi yentsimbi okanye ityhubhu eqinileyo engenanto ngokugqobhoza, kwaye emva koko ishushu esongwayo, ebandayo eqengqelekayo okanye ebandayo. icandelo lolawulo oluphakathi kwaye lisetyenziswa ngokubanzi njengombhobho wokuhambisa ulwelo.Xa kuthelekiswa nentsimbi eqinileyo efana nentsimbi ejikelezayo, umbhobho wensimbi unokugoba okufanayo kunye namandla ajikelezayo kwaye ulula.Yintsimbi yecandelo loqoqosho.Isetyenziswa ngokubanzi ekwenziweni kwamacandelo esakhiwo kunye namalungu oomatshini, anjengombhobho wokugaya ioyile, ishafti yokuhambisa imoto, isakhelo sebhayisekile kunye nombhobho wentsimbi osetyenziswa ekwakheni.
Intshayelelo emfutshane yokusetyenziswa kombhobho ongenamthungo
Ityhubhu yentsimbi engenamthungo yahlulwe yaba ityhubhu yentsimbi eshushu eqengqiwe (eyongeziweyo) engenamthungo kunye nokuzoba okubandayo.
n (iqengqiwe) ityhubhu yentsimbi engenamthungo.Ityhubhu epholileyo (eqengqelekayo) yohlulwe ibe ityhubhu engqukuva kunye netyhubhu ekhethekileyo eneentlobo ezimbini.Umbhobho wensimbi ongenamthungo kwaye ngenxa yokusetyenziswa kwayo okwahlukeneyo kwahlulahlulwe kwiintlobo ezininzi ezilandelayo: 1. Iityhubhu zentsimbi ezingenamthungo zokusetyenziswa kwesakhiwo (GBT8162-2008).Ikakhulu isetyenziselwa isakhiwo esiqhelekileyo kunye nesakhiwo soomatshini.Izinto zayo ezimele (i-brand) : I-Carbon Steel, i-20,45 intsimbi;I-Alloy Steel Q345,20CR, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, njl.2. Iityhubhu zentsimbi ezingenamthungo zokuhanjiswa kwamanzi (GBT8163-2008).Imodeli eluncedo isetyenziswa ikakhulu ukuhambisa umbhobho wolwelo kubunjineli kunye nezixhobo ezikhulu.Imele iMaterial (brand) ye20, Q345, njl.3. IIMTHUBU ZEntsimbi EZINGAMTHUNGO EZINGAPHANTSI neziphakathi (GB3087-2008) zityhubhu zentsimbi eziqengqelekayo nezitsalwa ngokubanda ezenziwe ngentsimbi ekumgangatho ophezulu wekhabhoni yezakhiwo ezahlukeneyo zebhoyila yoxinzelelo oluphantsi noluphakathi kwityhubhu yomphunga, iityhubhu zamanzi abilayo. kunye neetyhubhu zomsi ezishushu kakhulu, iityhubhu ezinkulu zomsi, iityhubhu ezincinci zomsi kunye neetyhubhu zezitena.Izinto ezimele intsimbi ye-10,20.
Iityhubhu zentsimbi ezingenamthungo (GB6479-2000) zoxinzelelo oluphezulu lwezixhobo zesichumisi zekhemikhali zikumgangatho ophezulu wekhabhoni yentsimbi yesakhiwo kunye nentsimbi yentsimbi engenamthungo iityhubhu ezifanelekileyo kwizixhobo zekhemikhali kunye nemibhobho enobushushu obusebenzayo obuyi-40 ~ 400 °C kunye noxinzelelo lokusebenza lwe-10 ~ 30 ma. .Izinto ezimele i-20,16MN, i-12CrMo, i-12Cr2Mo kunye nokunye.6. IIIBHAYIBHILE ZENKANTSI EZINGAQHELEKANGA ZE-PETROLEUM UKUNQOKA (GB9948-2006).Imodeli eluncedo isetyenziswa ikakhulu kwizibilisi, izitshintshi zobushushu kunye nemibhobho ehambisa ulwelo kwizinyibilikisi zepetroleum.Izinto zayo ezimele i-20,12CRMO, 1Cr5Mo, 1Cr19Ni11Nb njalo njalo.Bulala.Umbhobho wensimbi wokugaya i-geological drilling (YB235-70) luhlobo lombhobho wensimbi yokugaya i-core, enokuthi ihlulwe ibe ngumbhobho wokubhobhoza, i-collar drill, i-core pipe, i-casing kunye nombhobho wokumisa.8. Umbhobho wensimbi ongenamthungo (GB3423-82) we-diamond core drilling ngumbhobho wensimbi ongenamthungo wombhobho wokubhobhoza, intonga engundoqo kunye ne-casing.9. Umbhobho wokugaya ioli (YB528-65) ngumbhobho wensimbi ongenamthungo osetyenziselwa ukujiya ngaphakathi okanye ngaphandle kweephelo ezimbini zombhobho wokugaya ioli.Umbhobho wensimbi uhlukaniswe kwiintlobo ezimbini: ucingo olujikayo kunye nocingo olungaguqukiyo.Umbhobho wocingo ojikayo udityaniswe ngokudibeneyo, kwaye umbhobho wocingo ongaguqukiyo udibaniswa nesixhobo sokudibanisa nge-butt welding.10. I-Carbon kunye ne-carbon manganese yentsimbi yeetyhubhu ezingenamthungo kwiinqanawa (i-GB / t 5312-2009) zifanelekile ukuveliswa kwe-Marine grade I, II, ibhoyila kunye ne-superheater carbon kunye ne-carbon manganese steel ishubhu zentsimbi ezingenamthungo.Iityhubhu zentsimbi ezingenamthungo zenkqubo yombhobho woxinzelelo zahlulwe zibe ngamabakala ama-3 ngokoxinzelelo loyilo kunye nobushushu boyilo.Ubushushu obusebenzayo bodonga lwentsimbi engenamthungo kwibhoyila kunye neheater enkulu aliyi kudlula i450 °C.526/2000
Bulala.Ityhubhu yentsimbi engenamthungo (i-GB3088-82) yomkhono we-axle ye-axle yemoto luhlobo olukumgangatho ophezulu wekhabhoni yolwakhiwo lwentsimbi kunye ne-alloy yolwakhiwo lwentsimbi eshushu-eqengqelekayo ityhubhu yentsimbi engenamthungo yomkhono we-axle ye-axle yemoto kunye ne-axle yendlu ye-axle shaft ityhubhu.12. Umbhobho we-oyile woxinzelelo oluphezulu lwe-injini ye-diesel (GB3093-86) ngumbhobho wensimbi ongenamthungo otsalwa ngokubanda wokwenza umbhobho woxinzelelo oluphezulu lwenkqubo yokutofa kwe-injini ye-diesel.13. Iityhubhu zensimbi ezingenamthungo ezichanekileyo ngaphakathi ngaphakathi (GB8713-88) zehydraulic kunye ne-pneumatic cylinders ziityhubhu zentsimbi ezitsalwa ngokubanda okanye eziqengqelekayo ezichanekileyo nezingenamthungo ezinobungakanani obuchanekileyo bangaphakathi bomlinganiselo wokwenziwa kweesilinda zehydraulic kunye nepneumatic.14. Iityhubhu zentsimbi ezingenamthungo ezibandayo ezibandayo okanye ezibandayo (i-GB3639-83) zineetyhubhu zentsimbi ezingenamthungo ezitsalwa ngokubanda okanye ezigqitywe ngokucokisekileyo ezinomgangatho ophezulu wokuchaneka kunye nokugqiba kakuhle koMphezulu kwizakhiwo zoomatshini, izixhobo zehydraulic.Ukukhethwa kombhobho wentsimbi echanekileyo owenziwe ngomatshini okanye izixhobo ze-hydraulic, unokusindisa kakhulu ixesha lomatshini, ukuphucula ukusetyenziswa kwezinto, kunye nokunceda ukuphucula umgangatho wemveliso.
