1. Iimpawu zezinto kunye neenkcukacha ezisemgangathweni
I-34CrMo4 yintsimbi yokwakha ye-chromium-molybdenum alloy, edla ngokusetyenziselwa ukuvelisa iisilinda zegesi ezinoxinzelelo oluphezulu, iisilinda kunye nezinye iindawo ezineemfuno ezingqongqo zokusebenza. Ngokwembono yemigangatho emiselweyo, yenye yezinto zentsimbi ye-alloy ezichazwe ngokucacileyo kwi-EN 10083-3 esemgangathweni yaseYurophu, kwaye ikwahlangabezana neemfuno ezifanelekileyo ze-GB 18248 esemgangathweni yaseTshayina, ngokungathandabuzekiyo inika isiqinisekiso esithembekileyo somgangatho wayo kunye nokusebenza kwayo. Inamandla aphezulu, ukumelana nobushushu okugqwesileyo kunye nokumelana nokudinwa. Imigangatho yokusetyenziswa kwemibhobho yentsimbi engenamthungo ye-34CrMo4 yeisilinda zegesi yahlukahlukene kakhulu, igubungela imigangatho emininzi yesizwe neyehlabathi. Oku kuquka
Umgangatho waseTshayina: GB/T 18248-2021 (kwiityhubhu zesilinda yegesi kuphela)
Umgangatho waseYurophu: EN 10083-3/EN 10297-1
Umgangatho wamazwe ngamazwe: ISO 11120
Umgangatho waseMelika: ASTM A372/A372M-3
Umgangatho waseJapan: JIS G 3429

I-elementi	C	Si	Mn	P≤	S≤	Cr	Mo	okunye
Umxholo	0.30-0.37%	≤0.40%	0.60-0.90%	0.020%	0.020%	0.90-1.20%	0.15-0.30%	I-Ni≤0.30% I-Cu≤0.20%

Qaphela: I-phosphorus kunye nesalfure iyonke ≤ 0.030%

3.Ukusebenza kakuhle koomatshini

Emva konyango lobushushu kunye nokupholisa (ukucima + ukupholisa), umbhobho wentsimbi engenamthungo we-34CrMo4 unamandla okutsalwa kwe-≥980MPa, amandla okuvelisa e-≥835MPa, kunye nokwandiswa kwe-≥12%. Kwiqondo lobushushu eliphantsi le--50°, amandla okuchaphazela asenokuba yi-≥27J.

4. Amanqaku aphambili enkqubo yemveliso
1. Inkqubo yokuvelisa:
Ukusebenzisa inkqubo yokudweba eshushu/ebandayo engenamthungo → ukufunyanwa kweziphene ze-ultrasonic (UT) → ukucima nokulungisa (ukucima + ukufudumala) → uvavanyo lwe-hydraulic → ukuhlolwa kwemveliso egqityiweyo
2. Imeko yokuhanjiswa:
Ngokuqhelekileyo ihanjiswa ikwimeko yokutsalwa okanye yokubanda, unyango lokugqibela lobushushu luyafuneka emva kokuba kusetyenzwe ngumsebenzisi wokugqibela.
5. Unxibelelwano phakathi kwamanqanaba asekhaya
I-34CrMo4 igcina igama elifanayo kwimigangatho yesiTshayina, kwaye ukusebenza kwayo kufana noku:
GB/T 3077: 34CrMo
Amanqanaba afanayo: 42CrMo (ulwakhiwo kufuneka lulungiswe)
6. Iindawo eziqhelekileyo zokusetyenziswa

Ishishini	Isicelo esithile	Iimfuno zokusebenza
Ukugcinwa kwamandla kunye nokuthuthwa	Iisilinda ze-CNG/LPG, iisilinda zokugcina i-hydrogen	Ukuthwala koxinzelelo oluphezulu (20-35MPa)
Izixhobo zonyango	Iisilinda zeoksijini zonyango	Ubumsulwa obuphezulu (umxholo ophantsi we-S/P)
Izixhobo zokulwa nomlilo	Iisilinda zokuphefumla, iisilinda zokucima umlilo	Ukuqina kwempembelelo kubushushu obuphantsi
Uthutho	Iisilinda zenkqubo yeebhuleki zezithuthi zorhwebo	Ukudinwa okuchasene nokungcangcazela
Umkhosi kunye neenqwelo-moya	Iitanki zepropellant	Ukucubungula iinkozo ezicolekileyo kakhulu

8. Iindawo eziphambili zokusetyenziswa ze-34CrMo4
I-34CrMo4, njengesixhobo se-chromium-molybdenum steel alloy, isetyenziswa kakhulu ekuveliseni izixhobo zepayipi zentsimbi ezingenamthungo zeesilinda zegesi/iisilinda zentsimbi ezinoxinzelelo oluphezulu kunye nezikhongozeli zoxinzelelo oluphezulu. Kwimisebenzi ebonakalayo, isetyenziswa kakhulu ekuveliseni iisilinda ze-CNG, kuquka ukwenziwa kweesilinda zegesi yendalo ezicinezelweyo zezithuthi kunye nezinye iisilinda zeekhonteyina ezinoxinzelelo oluphezulu, ezibonelela ngenkxaso yezinto ezithembekileyo kwezi ndawo.
