Emkhakheni oguqukayo wobuchwepheshe bezimboni, indima yeizimpawu mechanicalivelele, ifakazela ithonya eliyisibopho ekusebenzeni kahle kwemishini.Okuphakathi kwalezi zingxenye ezibalulekile amaringi ophawu, isizinda esithakazelisayo lapho ukunemba kobunjiniyela kuhlangabezana nesu lokuklama elingenasici.Lesi sihloko singena phakathi kokucatshangelwa kwedizayini okuhilelekile ekucabangeni nasekukhiqizeni izindandatho zotywino ezisebenza kahle.Hlola ukuthi okuguquguqukayo okubalulekile okunjengokukhethwa kwempahla, izimo zokusebenza, imingcele yejiyomethri, phakathi kokunye, kusebenzisana kanjani kule nkulumo ehlanganisa yonke into ukuze kunikele ekwakhiweni kwendandatho yophawu echaza kabusha ukwethembeka kokusebenza.
Impahla ekhethelwe iringi yakho yophawu ingaba nomthelela omkhulu ekusebenzeni kukonke kanye nokuhlala kwayo yonke isistimu yomshini.Ngakho-ke, kubalulekile ukulinganisa ngokucophelela ukusebenza nokuqina lapho kuthathwa lesi sinqumo esibalulekile.
Okokuqala, kubalulekile ukubheka ngale kokuqina namandla enqubweni yokukhetha impahla.Isibonelo, ngenkathi izitsha zobumba zivame ukuphawulwa ngamazinga azo obulukhuni ahlaba umxhwele, zingase zithambekele ekubeni brittleness ngaphansi kwezimo ezithile.Ngokuphambene, izinketho ezithambile ezifana nama-elastomers zinikeza ukuguquguquka nokumelana ngokumelene nokuguga kodwa zingase zingabambeki kahle ngaphansi kwezimo zokushisa okuphezulu.
Ukuhambisana kwezinto ezibonakalayo noketshezi olusebenzayo kungenye into enkulu ekukhetheni izinto zendandatho yophawu.Ezinye izinto zingase zibangele ukuthi izinto ezithile zivuvuke noma ziwohloke ngokuhamba kwesikhathi;ngaleyo ndlela kuthinte kabi ubuqotho besistimu yakho yokuvala uphawu.Kubalulekile ukuthi into ekhethiwe imelane nokuguguleka noma ukucekelwa phansi kusuka kunoma imaphi amakhemikhali noma uketshezi oluhilelekile ohlelweni lwesistimu.
Ngaphezu kwalokho, ukuphumelela kwezindleko kufanele kuhlale kucatshangelwa.Nakuba ezinye izinto ezisetshenziswayo zingase zibonise izici zokusebenza eziphakeme, izindleko zazo eziphakeme zinganciphisa ukuba nokwenzeka kwazo ngaphakathi kwemikhawulo yesabelomali.Ukulinganisa ikhwalithi nokufinyeleleka kuqinisekisa njalo ukuklama okuphumelelayo ngaphandle kokuphazamisa ukusebenza.
I-Thermal conductivity nayo idlala indima ebalulekile ekukhetheni izinto ezibonakalayo.Ngokuya ngamazinga okushisa okusebenza kwesistimu, kungase kubaluleke kakhulu ukukhetha okokusebenza okuphezulu kwe-thermal conductivity okungaqeda ukushisa ngokuphumelelayo - ngaleyo ndlela uqinisekise ukusebenza okuphelele kophawu lwakho lomshini.
Okokugcina, ukunamathela ezindinganisweni ezifanele nemithethonqubo ngeke kushaywe indiva - izitifiketi zezinto ezibonakalayo ezifana nokuthobela i-FDA (uma zikhona) kufanele zifake esinqumweni sakho sokugcina sokukhetha ukuze uqinisekise ukuphepha komsebenzisi kanye nokuqondisa imithetho.
Ukucatshangelwa kweJomethrikhi
Izici eziyisisekelo zejiyomethri zifaka phakathi ububanzi, ububanzi bobuso, ukujula nobubanzi bendawo, kanye nanoma yimiphi eminye imininingwane yedizayini eklanyelwe ukuhambisana nezidingo zemishini.
Ububanzi bendandatho yophawu buxhumene ngokuqondile namandla ayo okusebenza.Ilawula inani lamandla asetshenziswayo ebusweni bokuvala futhi ithinta izici ezifana nokugcinwa nesivinini.Ngakho-ke, ukuhlaziya okuphelele kobukhulu bezingxenyekazi zekhompuyutha kufanele kube khona ngaphambi kokufika ngosayizi ofanele wendandatho yakho.
Ububanzi bobuso, enye ipharamitha yejiyomethri ebalulekile, incike kakhulu kukho kokubili ingcindezi nezimo zokusebenza kwezinga lokushisa.Ububanzi bobuso obubanzi buvame ukusetshenziselwa izinhlelo zokusebenza ezinesivinini esikhulu ukuphatha ukuchithwa kokushisa ngempumelelo.Ngokuphambene, ububanzi bobuso obuncane bungase bufaneleke kakhulu ekusebenzeni lapho izinkinga zesikhala ziyinkinga.
Okulandelayo kuza ukujula kwe-groove nobubanzi obubambe ukubaluleka okuphawulekayo ngenxa yethonya lazo phezu kokuguqulwa kwe-elastomer ngaphansi kwezimo zomthwalo nangesikhathi sokufakwa.I-groove ejulile enganele ingase iholele ekulimaleni kwe-extrusion noma ukwehluleka kokuvala uphawu kwangaphambi kwesikhathi;kuyilapho imifantu ejule ngokweqile ingase ibe nomthelela omubi ekuzinzeni kwe-seal futhi ikhawulele ikhono lendlala lokubhekana nokuchezuka kweshaft.
Okokugcina, amadizayini akhethekile angafakwa ngokuya ngezidingo eziqondene necala elithile njengamadivayisi amelene nokuzungezisa noma izici zokuqondanisa ukuze kumiswe kahle ihadiwe—lokhu kuguqulwa komuntu ngamunye kuqinisekisa ukusebenza okungenazihibe okuhambisana nezinzuzo zesikhathi eside sokuphila.
Kubalulekile ukwenza ukuphindaphinda okuqinile phakathi nesigaba sakho sokuklama ngokusebenzisa isofthiwe yokumodela ye-3D ethuthukisiwe noma umshini wokuhlola i-prototype.Lo mkhuba usiza ukukhomba izinselele ezingaba khona ezihambisana nezici zejiyomethri kusengaphambili kuyilapho uthuthukisa ukuthembeka kokusebenza komkhiqizo wakho kanye nokonga kwezindleko ngasikhathi sinye.
Ukucatshangelwa kokulinganisa
Ukucatshangelwa kokulinganisa kudlala indima ebalulekilemechanical seal ringumklamo.Ikakhulukazi, izindandatho zophawu ezilinganiselayo zisakaza ingcindezi ngokulinganayo nxazonkeubuso obuvaliwe, ukuthuthukisa ukusebenza kwayo nokuphila isikhathi eside.
Ukhiye wendandatho yophawu ebhalansiswe kahle usekulawuleni umehluko wengcindezi kuyo yonke indlela yokuvala.Idizayini enokulinganisela kahle igcina ingcindezi yobuso ephansi futhi inciphisa ukukhiqizwa kokushisa ngenkathi isebenza ngesivinini esiphezulu noma ngaphansi kwezimo zokucindezela okukhulu.Lokhu kunciphisa kakhulu izinga lokuguga futhi kuphakamisa ukusebenza kahle, okuqinisekisa ukuthi izimpawu zakho zigcina ukusebenza kwazo isikhathi eside.
Isilinganiso phakathi kwendawo echayeke kungcindezi yesistimu kanye nengqikithi yendawo ethinta iringi yokukhwelana isetshenziselwa ukuchaza “ibhalansi” ngamagama obuchwepheshe.Empeleni, isilinganiso esincishisiwe sebhalansi sihambisana namandla okuvala aphansi ebusweni bophawu.Ngakho-ke, ukuklama izilinganiso ezihlukahlukene zebhalansi kungasiza ukulawula la mandla.
Ukuze uthole ibhalansi ephumelelayo kumiklamo yakho yomshini wophawu, kubalulekile ukucabangela izici ezifana nezimfuneko zohlelo lokusebenza, imininingwane yedivayisi, izici zoketshezi (ezifana ne-viscosity), kanye nezimo zemvelo (njengezinga lokushisa nokucindezela).Ukucatshangelwa kwalezi zici kuvumela onjiniyela ukuthi banqume ukuthi umakhenikhani uphawu olungalinganiseli noma olulinganiselayo lufaneleka kakhulu kuhlelo olunikeziwe.
Izimo zokusebenza
Izinga lokushisa lendawo lapho indandatho yophawu izovezwa khona iyipharamitha ebalulekile.Ezilungiselelweni zokushisa okuphezulu, izinto ezithile zingase zilahlekelwe amandla noma ziwohloke, zinciphise amandla azo okuvala.Ngokufanayo, amazinga okushisa aphansi kakhulu angabangela izinto ukuthi zibe brittle futhi ziphuke.
Ukucindezela nakho kuyisici esibalulekile.Izindawo ezinengcindezi ephezulu zidinga ukumiswa kophawu olungamelana nokuguquka ngaphansi kwemithwalo enzima.Kuyaphawuleka lapha ukuthi ingcindezi ingahluka kakhulu ngesikhathi sokusebenza - ngakho-ke, ezimweni ezinjalo, abaklami kufanele bahlose ukubeka uphawu olungamelana nemithwalo yengcindezi eguquguqukayo ngaphandle kokuphazamisa ukusebenza.
Ukuhambisana kwamakhemikhali akufanele kunganakwa;ukucabangela ukuthi impahla yophawu ingamelana nokugqwala kunoma iluphi uketshezi noma amagesi akhona endaweni yayo yokusebenza kubalulekile ngoba izinto ezigqwalayo zingaguga noma zonakalisa izingxenye ezibucayi zesistimu yokuvala.
Ngaphezu kwalokho, ukucabangela isivinini sokusebenza kubalulekile ekwakhiweni kwendandatho yezinsimbi njengoba lokhu kungaletha imithwalo eguquguqukayo edala ingcindezi engalindelekile kuma-seal futhi kubangele ukuguga nokudabuka ngokushesha noma ngisho nokuhluleka kwesistimu kakhulu.Futhi, ukukhetha imiklamo efanele ekwazi ukubhekana nokuhuzuka okubangelwa ukusebenza kwesivinini esikhulu kuba semqoka ngalokho.
Ekuphetheni
Sengiphetha, idizayini yeringi yomshini wophawu incike kakhulu ezintweni ezinqumayo ezihlanganisa ukusebenza kwayo, ukuhambisana kwezinto ezibonakalayo, ingcindezi kanye namazinga okushisa phakathi kwezinye izici.Ukucatshangelwa ngokucophelela lezi zakhi kubalulekile ekuqinisekiseni ukusebenza kahle, ukuphila isikhathi eside nokuqina kwale ngxenye ebalulekile.
Ukwehlukahlukana kwezidingo izimboni ezihlukene ezizethulayo ukuze kutholakale izixazululo zokuvalwa kwemishini kugcizelela isidingo seseluleko sochwepheshe nokwenza ngokwezifiso isimo ngasinye esiyingqayizivele.Ukuhlonza izinto ezisetshenziswayo ezifanele kanye nokucushwa kwezigxivizo ukuze kunqobe ngisho nezimo zokusebenza ezinzima akubandakanyi nje uchwepheshe bezobuchwepheshe kodwa nolwazi oluqondene nemboni kanye nokuzibophezela okuphelele kwikhwalithi.
