Kwingcaciso, kunjaloI-DIN2391-1.Izinto ezisetyenziswayo zemibhobho yensimbi ye-hydraulic zicutshungulwa ngokuzotywa ngokuchanekileyo, ukunyangwa kobushushu obukhanyayo okungekho oxidation (i-NBK state), uvavanyo olungonakalisi, ukugungxulwa koxinzelelo oluphezulu kunye nokuhlanjwa kweasidi kwimingxuma yangaphakathi yemibhobho yentsimbi, unyango lokuthintela umhlwa. iindonga zangaphakathi nangaphandle zemibhobho yentsimbi kunye neoli yobungqina bokuhlwa, kunye nonyango lokuthintela uthuli olunezigqubuthelo ezimbini zokuphela.Umbhobho wensimbi oveliswayo unokuchaneka okuphezulu kunye nobuhle obuhle.Iindonga zangaphakathi nangaphandle zombhobho wensimbi ye-hydraulic ayinayo i-oxide layer, kwaye umbhobho wensimbi unokumelana noxinzelelo oluphezulu lokuhamba kwamanzi.Umbhobho wensimbi awuguquki ngexesha lokugoba okubandayo, kwaye unokwandiswa okanye utyunjwe ngaphandle kokuqhekeka.Iimpawu zoomatshini zinokugoba ngaphandle kokuguqulwa kuyo nayiphi na imbono.Isetyenziselwa ikakhulu ukwenza imibhobho yentsimbi kwiisekethe zeoyile ye-hydraulic system, eyaziwa ngokuba yimibhobho enzima kwiinkqubo zamanzi.Imibhobho yentsimbi ecocekileyo isetyenziswa ngokuqhelekileyo kwiimoto, ezinomlinganiselo wangaphandle oqhelekileyo (D) Φ 4mm-76mm, ubukhulu bodonga (S) 0.5mm-6.0mm.
Ubude bubude obumiselweyo beemitha ezi-6 (ngaphandle kwe-customized), kwaye imeko yokuhanjiswa yi-NBK (eqhelekileyo), i-GBK (i-annealed), kunye ne-BKS (i-stress relieved annealing).Abathengi abaneliseke ngeemfuno zokuchaneka okuphezulu, ukuguda okuphezulu, amandla okuqina, kunye neempawu zomatshini zemibhobho yentsimbi, njenge-ST35, ST37.4 (10 #), ST45 (20 #), ST55 (35 #), kunye ne-ST52 (16Mn), zikhethwa njengezona zinto ziphambili.
Kwingcaciso, yi-DIN2391-1.Izinto ezisetyenziswayo zemibhobho yensimbi ye-hydraulic zicutshungulwa ngokuzotywa ngokuchanekileyo, ukunyangwa kobushushu obukhanyayo okungekho oxidation (i-NBK state), uvavanyo olungonakalisi, ukugungxulwa koxinzelelo oluphezulu kunye nokuhlanjwa kweasidi kwimingxuma yangaphakathi yemibhobho yentsimbi, unyango lokuthintela umhlwa. iindonga zangaphakathi nangaphandle zemibhobho yentsimbi kunye neoli yobungqina bokuhlwa, kunye nonyango lokuthintela uthuli olunezigqubuthelo ezimbini zokuphela.Imibhobho yentsimbi eveliswayo inokuchaneka okuphezulu kunye nobuhle obuhle.Akukho luhlu lwe-oxide kwiindonga zangaphakathi nangaphandle zemibhobho yensimbi.Imibhobho yensimbi inokumelana noxinzelelo oluphezulu lokuhamba kwamanzi, kwaye imibhobho yensimbi ayiguquki ngexesha lokugoba okubandayo.Ziyakwazi ukwandiswa okanye ukucandwa ngaphandle kokuqhekeka.
Iimpawu zoomatshini zinokugoba ngaphandle kokuguqulwa kuyo nayiphi na imbono.Isetyenziselwa ikakhulu ukwenza imibhobho yentsimbi kwiisekethe zeoyile ye-hydraulic system, eyaziwa ngokuba yimibhobho enzima kwiinkqubo zamanzi.Imibhobho yentsimbi ecocekileyo isetyenziswa ngokuqhelekileyo kwiimoto, ezinomlinganiselo wangaphandle oqhelekileyo (D) Φ 4mm-76mm, ubukhulu bodonga (S) 0.5mm-6.0mm.Ubude bubude obumiselweyo beemitha ezi-6 (ngaphandle kwe-customized), kwaye imeko yokuhanjiswa yi-NBK (eqhelekileyo), i-GBK (i-annealed), kunye ne-BKS (i-stress relieved annealing).Abathengi abaneliseke ngeemfuno zokuchaneka okuphezulu, ukuguda okuphezulu, amandla okuqina, kunye neempawu zomatshini zemibhobho yentsimbi, njenge-ST35, ST37.4 (10 #), ST45 (20 #), ST55 (35 #), kunye ne-ST52 (16Mn), zikhethwa njengezona zinto ziphambili.
Intshayelelo kumgangatho waseYurophuEN10305-4:2003kwimibhobho yentsimbi ye-hydraulic: Imibhobho yentsimbi ye-hydraulic eveliswe kakuhle iyimibhobho engenamthungo emva komzobo ocolekileyo obandayo, owenziwe nge-oxygen free tempering treatment ukuphelisa uxinzelelo lwangaphandle kunye lwangaphakathi, kwaye emva koko nge-phosphating kunye nonyango lokuthintela umhlwa.Imveliso inokuchaneka komgangatho ophezulu, i-ductility elungileyo, kwaye inokucutshungulwa ngokulula kwaye igobe kwiimilo ezahlukeneyo ezinqwenelekayo ngaphandle kokunciphisa okanye ukuthambisa umbhobho onqamlezayo;Umphandle wangaphandle wombhobho unobuchwephesha obuphezulu kwaye unzima ngokulinganayo emva kokunyangwa kwe-oxygen free tempering, okwenza kube lula ukudibanisa kunye neeclamps.Umngxuma wangaphakathi kunye nomphezulu wangaphandle unokufakwa ngokuthe ngqo ngaphandle kwesidingo sokucoca i-asidi kunye nokususwa komhlwa emva kwe-phosphating kunye nonyango lokuthintela umhlwa.
