Umshini wokufaka oshisayo wokufakwa kokuthwala, umkhono wokuthwala, ukufakwa kwe-axle yokuthwala
incazelo yomkhiqizo
Lo mshini wokushisisa ongeniswa yizimboni wenzelwe ukunemba kwezinhlelo zokusebenza zokufaka ukushisa ekufakweni okuthwala, imikhono, nokufakwa kwe-asi kuzo zonke izimboni ezisindayo. Isebenzisa ubuchwepheshe bokungeniswa kwe-electromagnetic, ihlinzeka ngokufudumeza okusheshayo, okulawulwayo (kufika ku-1200 ° C) ngokusatshalaliswa kwezinga lokushisa okufanayo ukuze kuqinisekiswe ukuhlangana kokuphazamiseka ngenkathi kuvimbela ukulimala okushisayo ezingxenyeni. Uhlelo luhlanganisa ukulawulwa kwamandla okuguquguqukayo (ububanzi obungu-15-180kW) kanye nokuqapha izinga lokushisa kwesikhathi sangempela ngama-pyrometer ahlanganisiwe, okuvumela ukuhlanganiswa okungenamthungo nemigqa yokukhiqiza ezenzakalelayo. Idizayini yayo ehlangene, eqinile ivumela ukusetshenziswa kweshabhu yokusebenzela engashintshi kanye nezinhlelo zokusebenza zamaselula emikhakheni ye-aerospace, yezimoto, kanye nemishini esindayo. Ukusebenza okuwonga amandla kunciphisa ukulahlekelwa ukushisa kuyilapho kugcinwa ukuchezuka kwe-
Ububanzi bohlelo lokusebenza
Lo mshini wokushisisa ongeniswa ezimbonini uklanyelwe ngokukhethekile ukufakwa kwezicelo zokufaka ukushisa okunembayo kuyo yonke imikhakha yezimboni ehlukahlukene, ikakhulukazi ekufakweni kwama-abheri, imikhono, ne-asili lapho kudingeka khona ukuhlanganiswa kokulinganisa ukuphazamiseka. Isebenzisa ubuchwepheshe bokungeniswa kwe-electromagnetic obuthuthukisiwe obunokulawula imvamisa okuguquguqukayo (1-400kHz), iletha ukufudumeza okusheshayo, okufanayo (kufika ku-1200 ° C) kuyilapho inciphisa ukucindezelwa okushisayo, iyenze ibaluleke kakhulu kumabheringi ezimoto adinga ukufana kwezinga lokushisa okungu-±3°C kanye nezingxenye ze-aerospace ezifuna ukunemba kwezinga le-micron. Uhlelo luhamba phambili emisebenzini esindayo njengama-shaft bearings amakhulu we-turbine yomoya (kufika ku-2m ububanzi), ukufeza imijikelezo yokuhlanganisa yemizuzu engu-30 ngokumelene nezindlela ezivamile zamahora angu-4, nokucushwa kwamandla okuhlanganisa u-15-200kW ukuze kuhlaliswe osayizi bezingxenye abahlukahlukene. Amandla ayo okushisa angathinteki afakazela ukuthi abalulekile ezindaweni ezivalekile njengezindlu zezimoto noma ama-gearbox assemblies, lapho ukushisisa ilangabi kungaba yingozi. Ubuchwepheshe buguqula imigqa yokukhiqiza emikhakheni yokukhiqiza ngokunika amandla ukuhlanganiswa okuzenzakalelayo - izingalo zerobhothi zingabeka amabhereri ashiselwe ngaphambili kuma-shaft phakathi kwamawindi amasekhondi angu-3, kuzuzwe imihlangano engu-80-120/ihora ngokunemba okuphindaphindwayo kokunwetshwa okungu-0.005mm. Ukusebenza kahle kwamandla kufinyelela ku-85%, kunciphisa ukusetshenziswa kweyunithi ngayinye ngo-70% uma kuqhathaniswa nezindlela zokugeza uwoyela, kuyilapho izici zokuphepha ezihlanganisa impendulo yokushisa kwe-infrared kanye nokuvalwa okuzenzakalelayo kuvimbela ukuwohloka kwezinto. Imiklamo yekhoyili eyenziwe ngokwezifiso ijwayela kumajiyometri ayinkimbinkimbi ukusuka emikhonweni enezindonga ezincanyana (5mm) ukuya kumashafti amakhulu afojiwe, ngokuguquguquka kwefrikhwensi kuqinisekisa ukujula kwesikhumba okufanelekile (0.5-5mm) wezinto ezahlukahlukene ezihlanganisa ama-alloys ebanga eliphezulu. Lesi sixazululo siqeda izinselelo zemihlangano evamile njengokuhlanekezela kwengxenye noma ukugxilisa ingqondo kwengcindezi, ukusungula amabhentshimakhi amasha wokunemba, ukukhiqiza nokuphepha kwendawo yokusebenza ezinqubweni zokufaka ukunwetshwa kokushisa.
Ukucushwa kanye nokusebenza
Umshini wokushisisa ongeniswa yizimboni usebenzisa ubuchwepheshe bokungeniswa kwe-electromagnetic obusezingeni eliphezulu obunokulawula okuguquguqukayo kwefrikhwensi (1-400kHz) ukuze kuzuzwe ukushisisa okusheshayo nokufanayo kwezinhlelo zokusebenza ezihlanganisa ukuphazamiseka. Ngokukhiqiza amaza ashintshashintshayo anemvamisa ephezulu ngamakhoyili aklanywe ngokunembile, idala ama-eddy currents ngaphakathi kwezingxenye zensimbi (amabheringi, imikhono, noma ama-ekseli), ivumela ukushisisa kwendawo ngamanani angu-50-200°C ngomzuzu kuyilapho igcina izinga lokushisa lilingana phakathi kuka-±3°C. Ikhono lokushintsha imvamisa yesistimu livumela ukulawulwa okuthuthukisiwe kokujula kwesikhumba (0.5-5mm) ezintweni ezihlukahlukene, kusukela emikhonweni enezindonga ezincanyana (5mm) ukuya kumashafu amakhulu afojiwe (ububanzi obungama-500mm). Le ndlela yokushisa engathinteki iqeda ukugxila kokucindezeleka okushisayo kanye nokuhlanekezelwa kwengxenye, okubalulekile kumabheringi ebanga le-aerospace edinga ukunemba kwezinga le-micron. Ama-pyrometer ahlanganisiwe ahlinzeka ngokugadwa kwezinga lokushisa kwesikhathi sangempela, okuqinisekisa ukufana okunembile kokukhula nokulingana okubaliwe kokuphazamiseka (isb., 0.05mm ngaphezu kobubanzi obungu-100mm ku-65°C).
Ifakwe amandla aphumayo aguqukayo asukela ku-15-200kW kanye nokulawulwa kwezinga lokushisa kwedijithali kufika ku-1200°C, umshini uletha inqubo ephindaphindekayo ephindaphindekayo. Uhlelo lwayo lokulawula olusekelwe ku-PLC lufinyelela ukuzinza kwezinga lokushisa elingu-±1°C ngempendulo ye-loop evaliwe, ukulungisa ngokuzenzakalelayo amapharamitha wengxenye ehlukene yejometri nezinto zokwakha (insimbi, ithusi, noma ama-alloys). Idizayini yekhoyili ye-modular ithatha ukwakheka kwezingxenye eziyinkimbinkimbi, kuyilapho ukuhlelwa kwezigaba eziningi kunika amandla amaphrofayela okushisa enziwe ngokwezifiso—okubalulekile kumabheringi amasondo ezimoto afuna ukufana okungu-±3°C. Izindlela zokuphepha zifaka ukuvikela ukushisa okushisayo kwe-infrared, isitobhi esiphuthumayo, nokuvalwa okuzenzakalelayo lapho kutholwa ama-gradients angavamile. Izixhumanisi ze-HMI ezisebenziseka kalula zivumela opharetha ukuthi bagcine amaresiphi asethiwe angu-50+, asiza ukushintshashintsha okusheshayo phakathi kwamaqoqo okukhiqiza. Ukusebenza kahle kwamandla kufinyelela ku-85%, kunciphisa ukusetshenziswa kweyunithi ngayinye ngo-70% uma kuqhathaniswa nezindlela zokugeza uwoyela.
Umshini uguqula imigqa yokukhiqiza ngokusebenza kahle okungenakuqhathaniswa, uqedele ukufakwa okunezinhlamvu ngamasekhondi angu-30-60—okuphindwe izikhathi ezingu-30 ngokushesha kunokushisa kwe-ovini okuvamile. Kumabheringi angu-φ100mm, ifinyelela imihlangano engu-80-120/ihora ngokunemba kokunwetshwa okungu-0.005mm, ihlanganisa ngaphandle komthungo nezingalo zerobhothi ukuze kumiswe ngokuzenzakalelayo phakathi kwamawindi amasekhondi angu-3. Emishinini eyinhloko ye-shaft ye-turbine yomoya (ububanzi obungu-2m), imijikelezo yokuhlanganisa incipha isuka emahoreni ama-4 iye kumizuzu engama-30. Ukwenziwa ngcono kwefrequency ethize kuqinisekisa ukusebenza kahle kokuguqulwa kwamandla okungu-95%: imvamisa ephezulu (200kHz) yezingxenye zodonga oluncane (
Itholakala kuzo zombili izinkundla zokusebenzela ezimile kanye namamodeli aphathekayo, isistimu ivumelana nezimo ezihlukene zezimboni. Amayunithi amile (200kW) afaka amasistimu okuthutha ahlanganisiwe emigqa yokukhiqiza yevolumu ephezulu, kuyilapho izinguqulo zeselula ezihlangene (15kW) zinika amandla ukuseviswa kwemishini esindayo esizeni. Ukwakhiwa kwe-modular kuvumela ukushintshwa kwekhoyili okusheshayo—ukushintsha ukusuka kuma-motor bearings amancane (φ20mm) kuye emikhono emikhulu yebhokisi lika-gearbox (φ500mm) phakathi nemizuzu eyi-15. Konke ukulungiselelwa kufaka phakathi izindawo ezivalekile ezinesilinganiso se-IP54 sokumelana nothuli/amanzi nokuvikela i-EMI ukuze kuvinjelwe ukuphazamiseka kogesi obucayi. Ukuxilongwa kwesilawuli kude ngokuxhuma kwe-IoT kunika amandla ukugcinwa okubikezelwayo, ukuhlaziya ubude bekhoyili (imvamisa imijikelezo engu-5,000) nokusebenza kwemojula yamandla.
Idizayinelwe ukuqina kwezimboni, umshini uziqhayisa nge-MTBF engaphezu kwamahora ayi-10,000 enezingxenye zemojuli ukuze usebenze kalula. Ama-inverter e-IGBT esifunda esiqinile athatha indawo yamashubhu e-vacuum evamile, ehlisa izinga lokuhluleka ngo-80%. Izinqubo zokulinganisa ezizenzakalelayo zihlola ukuqondanisa kwamakhoyili kanye namazinga okugeleza okupholisa (≥10L/min) ngaphambi komjikelezo ngamunye. Izimiso zokulungisa zibandakanya ukuhlolwa kwebhange le-capacitor kanye nokushintshwa kwe-coolant yonyaka, ukulungiswa okuningi kuqedwe amahora angaphansi kwama-4 kusetshenziswa izingxenye eziyisipele ezijwayelekile. Uhlelo lwamanzi oluvaliwe luhlanganisa amaphampu aphindwe kabili angasebenzi kanye nezihlungi zezinhlayiya (
