1. Ukuhlaziywa kwesakhiwo se-valve yesandla sesango
Njengengxenye eyinhloko yokusebenza kwezandla, iisondo le-valve yesangokunomthelela oqondile ekuvuleni kwe-valve nokuvala ukusebenza kahle kanye nempilo yesevisi ngenxa yokwakheka kwayo kwesakhiwo. Izingxenye eziyinhloko zihlanganisa:
| Izingxenye | Incazelo esebenzayo |
| Umzimba wesondo lesandla | I-torque ikhiqizwa ngokuzungezisa komuntu, futhi idizayini yobubanzi ithinta ngqo usayizi wetorque esebenzayo (uma umkhulu ubukhulu, umzamo omncane) |
| Indlela yokuxhuma i-valve stem | Yamukela ipheya yentambo ye-trapezoidal (uhlobo lwenduku evuliwe) noma eyakhelwe-ngomucu (uhlobo lwenduku emnyama) ukuze uzuze ukuguqulwa ukusuka ekunyakazeni okujikelezayo kuye kokunyakaza komugqa |
| Idivayisi yokukhiya | Idizayini yebhakede noma yokubeka iphinikhodi ukuze kuvinjelwe ukusebenzisa kabi |
2. Izimiso zemishini eyinhloko
1. Imishini yokudlulisa intambo
Idizayini yokubhanqa kwentambo ye-trapezoidal: kusetshenziswa intambo ye-trapezoidal angle yentambo engu-30 ukuze kuzuzwe ukusebenza kahle komshini okuphezulu (kufika ku-70% -90%)
Ifomula yokudlulisa ithoshi: T=F×r=2πηW×p
(T: i-torque yesondo lesandla, F: amandla okusebenza, r: irediyasi yesondo lesandla, W: umthwalo wesango, p: umthofu wentambo, η: ukusebenza kahle komshini)
2. Ukungqubuzana kanye{1}}nomphumela wokukhiya
I-Static friction coefficient (insimbi kuye kwibronze) μ≈0.1-0.15, iqinisekisa ukuthi ngeke ibuyele ngokuzenzakalelayo endaweni yayo yasekuqaleni ngemva kokuvula.
-Isimo sokuzikhiya: i-engeli yokuhola intambo < arctanμ, ngokuvamile idizayinwa Ngaphansi noma ilingana no-5 degree
3. Ukusetshenziswa komshini wezinto ezibonakalayo
| Uhlobo lokucindezeleka | Ibanga lenani elijwayelekile | Izinyathelo zokulwa |
| Ukucindezeleka kwe-Extrusion | 80-120 MPa | Sebenzisa i-ASTM A276 304 insimbi engagqwali |
| Shear stress | 45-65 MPa | Lungiselela idizayini yerediyasi yempande yefillet |
| Ukugoba ingcindezi | < 50% of material yield strength | Khulisa ububanzi besiqu se-valve kanye nenani lamaphoyinti okusekela amasondo esandla |
3. Ukuhlaziywa kwezimo zohlelo lokusebenza ezijwayelekile
1. Imboni ye-Petrochemical
Izimo zokusebenza: ingcindezi ephezulu (API 20000psi), izinga lokushisa eliphezulu (Ngaphansi noma elilingana ne-425 degree)
Idizayini ekhethekile:
Isakhiwo senduku emnyama ukuvimbela ukucwebezela okumaphakathi nokujama
Isondo lesandla elinwetshiwe (ububanzi Mkhulu noma bulingana no-500mm) ukuze kuncishiswe itorque yokusebenza
2. Uhlelo lwegesi yasemadolobheni
Izimfuneko zokuphepha:
Ifakwe idivayisi yokunciphisa ithoshi (Ngaphansi noma kulingana no-200N·m)
Uphawu lwesixwayiso olubomvu/oluphuzi lwesiqondiso sokuzungezisa
4. Imininingwane yokusebenza kanye nezindawo zokulungisa
1. Izinqubo zokusebenza ezijwayelekile
Isiqinisekiso- esigcwele sendawo evulekile: Ngemva kokuzungezisa phezulu, hoxisa ukujika okungu-1/2 ukuze uvimbele ukunwetshwa kwe-thermal kanye nokuminyana.
Ukuphatha okungavamile:
Ukusebenza kwe-torque eyeqisayo akuvunyelwe uma ugxuma (kunconywe inani elikhulu labasebenzi Ngaphansi noma obulingana no-400N)
Umjovo wekota wokulungisa we-NLGI grade 2 we-lithium-based grease for lubrication
2.Ukuxazulula inkinga okuvamile
| Iphutha elenzeka | Izinyathelo zokulwa zobuchwepheshe |
| I-handwheel idling | Hlola ukuguga kwepheya ye-valve stem thread (imvume evumelekile Ngaphansi noma ilingana no-0.3mm) |
| I-torque yokuvula nokuvala iyanda ngokuzumayo | Hlanza isikali ku-valve cavity noma shintsha uphawu lokupakisha 2 |
5. Amacala emboni kanye nokuqanjwa kabusha kwezobuchwepheshe
I-Hangzhou Xiaoshan Chuangye Metal Processing Co., Ltd.
Le nkampani ingumkhiqizi ochwepheshe kanye nomthengisi wamasondo ezandla ahlukahlukene. Yasungulwa ngo-2002 futhi ikomkhulu layo liseFenghuangshan Village, Idolobha laseJinhua, Isifunda saseXiaoshan, Idolobha laseHangzhou, imizuzu engu-30 kuphela uma uhamba ngemoto usuka e-Hangzhou Xiaoshan International Airport.
Imikhiqizo eyinhloko yenkampani yethu ihlanganisa amasondo esandla ensimbi engagqwali, amasondo okushisela, amasondo esandla anyathelayo, amasondo ezandla e-aluminium alloy, njll. Ngesikhathi esifanayo, ubukhulu, ukuma, umbala, ukwelashwa kwendawo, uphawu, njll.
Izinhlelo Ezihlukahlukene:
Amasondo ethu ezandla athola ukusetshenziswa okubanzi emishinini eminingi efana namavalvu, amaphampu, ama-reactors, izixube, amasango amanzi, amajeneretha, nokunye. Ukusebenza kwabo okuthembekile kuqinisekisa ukusebenza okungenamthungo kuzo zonke izinhlelo zokusebenza ezihlukene, okunomthelela ekusebenzeni kahle nasekusebenzeni kwemishini ebalulekile.
Isimo-se{1}}se{2}}IziNsiza Zokukhiqiza Ubuciko:
Ifakwe izinsiza zokukhiqiza zesimanje, inkampani yethu iziqhayisa ngemishini nobuchwepheshe obuthuthukile. Izinsimbi ze-CNC, imishini yokugaya, imishini yokumba, imishini yokushisela, imishini yokupholisha, imishini yokumboza, nokunye kwakha izikhali zamathuluzi asenza sikwazi ukuletha amasondo ezandla ekhwalithi engenakuqhathaniswa nokunemba.
6. Isibikezelo sentuthuko yesikhathi esizayo
Ukuthuthukiswa okuhlakaniphile: inzwa ehlanganisiwe ye-torque + imojula yokudlulisela engenantambo (isilinganiso sokungena esilinganiselwe singaphezu kwama-30% ngo-2026)
Ukuqamba izinto ezintsha:
I-Carbon fiber composite handwheel (ukunciphisa isisindo ngo-60%)
Ipheya-ezigcoba nge-ceramic coated
Ukubhekwa kwemboni: Ngokusetshenziswa kwezinga elisha le-API 6D-2024, ukwakheka kwe-ergonomic nokusebenza kwemishini
nokwenza kahle kweamasondo ama-valve esangoizogxila emqhudelwaneni wezobuchwepheshe. Usayizi wemakethe yomhlaba wonke kulindeleke ukuthi ukhule ngonyaka
izinga lika-6.8% kusukela ngo-2025 kuya ku-2030.
