Muva nje, uhlangothi lomshini olusebenzisa umoya lwaluyinkinga yomunye umuntu. Umklami wemishini wabeka uhlaka, wafaka amabhlogo okubeka indawo yamasilinda nama-valve bank, wabe esethumela imodeli kumthengisi wamandla oketshezi owahlola ukusebenza kwamapayipi, ubukhulu be-port, kanye nokulingana kwe-enclosure ephepheni (noma kuthuluzi elihlukile ngokuphelele). Kwathathwa umoya. Kwabe sekuthiwa i-prototype yakhala.
Namuhla izinombolo zokuhamba komoya zifika kuqala endaweni yokusebenza ye-CAD. I-Bore, i-stroke, izinga lomjikelezo, isidingo se-SCFM, i-valve Cv, ubukhulu be-port manifold, i-enclosure venting kanye ne-ingress rating: konke lokhu kwenziwa ngendlela efanayo ne-geometry, ngoba i-MCAD yilapho ukuhwebelana kuxazululwa khona.
Lolo shintsho lubalulekile kunoma ubani owakha imishini. Isilinda esibonakala kahle esihlanganisweni sisengalamba, sivuze, noma sipheke ama-solenoid aso ngesikhathi umoya wangempela usishaya.
Ukugeleza Komoya Kungokwasemodelini ye-CAD Kusukela Ekuqaleni
Isilinda somoya siyingxenye yejometri enesibopho sezinga lokugeleza esinamathiselwe. Imbobo kanye nokushaya okudonsayo kunquma ivolumu eshaywe. Imijikelezo ngomzuzu umshini okumele ushaye inquma ukuthi lelo volumu ligcwaliswa ngokushesha kangakanani. Ukucindezela kokuphakelwa kusetha ukuthi i-compressor kufanele ilethe umoya ongakanani wamahhala ukuze ihambisane. Yenza i-jometri ngaphandle kwalezo zinombolo bese uba nomzimba ofanelana ngaphakathi kwenhlangano elambile.
I-CAD eqaphela ukuhamba komoya iyeke ukuba yokuzikhethela esikhathini esidlule. I-SCFM appetite ye-actuator iqhuba ukukhethwa kwe-valve, i-valve Cv iqhuba ubukhulu be-port ku-manifold, kanye nokubekwa kwe-manifold kuqhuba ubude bepayipi, obubuyela emuva ekwehleni kwengcindezi, futhi ekugcineni, isivinini se-actuator. Hambisa noma yikuphi ukushintshashintsha okukodwa bese okunye kuhamba nakho. Kungcono ukubukela lokho kwenzeka kumodeli kunendawo yokubeka.
I-SCFM ne-CFM azifani
Leli gama libacasula kakhulu abaklami kunalokho okufanele. I-CFM ukugeleza kwevolumu kunoma yikuphi ukushisa kanye nengcindezi ekhona endaweni yokulinganisa. Lokhu kokubili akushintshisani. Ukukuhlanganisa yilokho okwenza umshini ungabi nakho ngokwanele.
Ukuze uthole ulwazi olucacile ngomehluko osebenzayo, nokuthi kungani ipuleti legama le-compressor i-SCFM lizohlala lidlula i-CFM yalo ngokucindezela komugqa, ukuhlukaniswa kwe-SCFM vs. CFM okuvela ku-Nigen kuyisiqalo esiwusizo sokugcina ibhukimakhi eduze kwendawo yokusebenza ye-CAD. Uma umehluko usuyimvelo yesibili, amashidi e-spec avela kubathengisi be-valve, isilinda, kanye ne-compressor ayayeka ukuphikisana.
Imininingwane Yokuhamba Komoya Iqhuba Imodeli Ye-Actuator
Ububanzi be-bore yinombolo eyodwa ebaluleke kakhulu oyidwebayo. Izikali zokusetshenziswa komoya ngesikwele se-bore, ngakho-ke i-actuator enobukhulu besinyathelo esisodwa phezulu ingaphinda kabili noma kathathu i-SCFM yonke ingxenye yesistimu okufanele iyidle. Ubude be-stroke bubalulekile futhi, kodwa ngokulandelana. Izinga lomjikelezo liphindaphinda noma ngabe isidingo se-stroke ngasinye sivela sinjani.
Esinye isithiyo sinobukhulu obufanayo. Uma i-actuator kufanele ishintshane nezingxenye ezingaphandle kweshelufu, i-geometry yayo yokufaka akuyona into eguquguqukayo yamahhala. Izindinganiso ezifana ne-ISO 6431 zamasilinda enduku eyodwa zilungisa amaphethini emigodi yokufaka, izintambo zezintambo, kanye nezindawo zembobo kulo lonke ububanzi bembobo obungu-32 kuya ku-320 mm. Imodeli ihambisana nejwayelekile kanye nanoma iyiphi isilinda efanelekile iwela ekuhlanganisweni. Imodeli i-freehand kanye nayo yonke insizakalo iba yingxenye yangokwezifiso.
I-Manifold Ishintsha Ukuhlanganiswa
I-manifold yilapho kunqunywa khona ezomnotho zokuhamba komoya. Ubukhulu bechweba kufanele bufane ne-Cv edingwa yi-actuators. Ibhlokhi ngokwayo kufanele ihlale eduze ngokwanele nalawo ma-actuators kangangokuthi ubude bepayipi abudli isabelomali sengcindezi. Futhi izinto kufanele zisinde kunoma yini eyenzeka endaweni ezungezile, kungaba yi-coolant inkungu, i-washdown, ukushisa okuzungezile, noma ukudlidliza.
Ukulingisa i-manifold njengomzimba wangempela, onobukhulu obuthile (hhayi ibhlogo lokubamba indawo) kuphoqa lezo zinqumo kusenesikhathi. Uyabona ukuthi i-valve stack ishayisana nelungu lohlaka oluseduze. Uyabona ukuthi i-exhaust ifaka umlilo yini ebhandeni lentambo. Uyabona ukuthi iphethini yokufaka ifika endaweni eyisicaba noma umthungo we-weld ongathandeki. Akukho nokukodwa kwalokho okubonakala ngendlela ehlelekile.
Izilinganiso Zokuvalelwa Zivimbela I-CAD Geometry
Indawo ebiyelwe enama-valve e-solenoid, ama-manifold, noma izilawuli zomoya kufanele igcine ingaphandle lingaphandle, futhi ngokuvamile, ivumele inani lokushisa elilawulwayo liphume. Uhlelo lokulinganisa lwe-NEMA luchaza ukuthi kusho ukuthini ukuthi “gcina ngaphandle” endaweni ethile (uthuli, uwoyela oconsayo, amanzi aqondiswa yipayipi, imimoya ebolile), futhi isilinganiso ngasinye sinemiphumela eqondile yejiyometri kumodeli.
Inzuzo Ivela Phansi
Ezansi, ikakhulukazi. Uma imininingwane yokuhamba komoya iqhuba imodeli kusukela ekuqaleni, izingxoxo zobukhulu be-valve nomhlinzeki we-pneumatic zithatha imizuzu esikhundleni sezinsuku. Ukuhamba kwamapayipi kufushane futhi kuqondile ngoba i-manifold ihlala lapho kudingeka khona.
Izikhathi zomjikelezo wesibonelo zifika eduze kwalezo ezibalwe ngoba ukwehla kwengcindezi kwakubhajethiwe, akuqagelwanga. Futhi indawo ebiyelwe ithunyelwa nesilinganiso sayo siphelele ngoba konke ukungena kwabuyekezwa ngokuhambisana ne-geometry yesivalo ngaphambi kokuba iphaneli yokuqala inqunywe.
Akukho kulokhu okudinga amathuluzi angajwayelekile. Kudinga i-SCFM, i-Cv, i-bore, i-stroke, kanye neklasi yokungena ukuze baphile ngemodeli njengezakhamuzi zesigaba sokuqala, hhayi kuspredishithi ehlukile akekho ovulayo kuze kube yilapho eqala ukusebenza.
