Izinto Ezibalulekile Okufanele Uzicabangele
- Ama-motor e-DC angenamabhulashi angu-24V afinyelela amazinga omsindo angu-≤50dB ngesikhathi sokusebenza komnyango okuzenzakalelayo, ukuhlangabezana nomkhawulo womsindo ophakanyisiwe yi-WHO ezindaweni zangaphakathi lapho ukugxilisa ingqondo nokuthula kubalulekile khona.
- Ubuchwepheshe bezimoto ezingenamabhulashi buqeda umsindo wokungqubuzana kwebhulashiekhiqiza amazinga omsindo aphezulu angu-10-15dB kuma-motor e-DC abhulashiwe endabuko, okwenza i-brushless ibe uhlobo olulodwa kuphela lwemoto olusebenzayo lwezinhlelo zokusebenza zomtapo wolwazi kanye nemyuziyamu.
- Izincazelo zezinga lomsindo kumele zifake izimo zokulinganisa(ibanga, umthwalo, isivinini) ngoba injini efanayo ingakhiqiza i-35dB uma ingasebenzi kanye ne-55dB uma igcwele umthwalo — incazelo ngaphandle kwemibandela ayinalutho.
- Abaqhubi bezicabha abazenzakalelayo njenge-YF150 enama-motor e-DC angama-24V angu-60W angenamabhulashi banikeza ukusebenza okungu-≤50dBngenkathi kugcinwa isivinini somnyango esingu-150-500 mm/s kanye namandla okulayisha afinyelela ku-300kg ngeqabunga ngalinye.
Kungani Izinga Lomsindo Liyiyona Nqubo Eyinhloko Yokukhetha Iminyango Ezenzakalelayo Ezindaweni Ezithule
Imitapo yolwazi, iminyuziyamu, izibhedlela, amalabhorethri ocwaningo, kanye nezindawo zokuzindla zifana nesidingo esifanayo: umsindo ozungezile kumele uhlale ungaphansi kwamazinga aphazamisa ukugxilisa ingqondo, ukuphulukiswa, noma ukuzindla.Ngoba izinhlelo zeminyango ezizenzakalelayo zisebenza izikhathi eziningi kuya kwezingamakhulu ngosuku ezindaweni zomphakathi ezinabantu abaningi abasebenzisa iminyango, umnikelo womsindo oqongelelekayo ovela ekusebenzeni kwemoto yomnyango ungadlula kakhulu umkhawulo womsindo wangemuva uma ubuchwepheshe bemoto obungalungile bucacisiwe. I-World Health Organization incoma amazinga omsindo ozungezile wangaphakathi angaphansi kuka-35dB ezindaweni ezidinga ukuhlushwa kanye nangaphansi kuka-40dB ezindaweni ezijwayelekile zangaphakathi, okwenza ukukhetha umsindo wemoto kube yincazelo ebalulekile yezindawo ezithule.
Umthelela womsindo wohlelo lomnyango oluzenzakalelayo uvela emithonjeni emithathu: injini ngokwayo (umsindo we-electromagnetic nomsindo wamabhere), indlela yokushayela (umsindo webhande, igiya, noma uchungechunge), kanye nokunyakaza kweqabunga lomnyango (ukuhamba komoya kanye nokungqubuzana kwethrekhi).Ubuchwepheshe bemoto ye-DC engenamabhulashiibhekana nomthombo wokuqala ngokuqeda isikhombimsebenzisi se-brush-commutator esidala umsindo omkhulu kuma-motor ajwayelekile axutshwe. Ukunciphisa umsindo okubangelwa yi-10-15dB kuguqula iminyango ezenzakalelayo kusukela ekuthwaleni umsindo ibe yingxenye yesikhungo esicishe sithule.
Kubaphathi bezikhungo abahlola izinhlelo zeminyango ezizenzakalelayo, imininingwane yomsindo kumele iphathwe ngendlela efanayo namandla omthwalo wesakhiwo kanye nezilinganiso zokuphepha komlilo.Uhlelo lomnyango oluhlangabezana nazo zonke ezinye izimfuneko kodwa oludlula umkhawulo womsindo alufaneleki ngokuphelele ukusetshenziswa kwendawo ethule, kungakhathaliseki intengo yayo, izici zayo, noma idumela lomkhiqizo. Lokhu kwenza ukuhlolwa kwezinga lomsindo kanye nokuqinisekiswa kube yinqubo yokuphasa/ukwehluleka enqubweni yokuthenga.
Indlela Ubuchwepheshe Bezimoto Ze-DC Ezingenamabhulashi Obufinyelela Ngayo Ukusebenza Komsindo Okuyi-≤50dB
Inzuzo yomsindo wama-motor e-DC angenamabhulashi kunezinjini ezixutshwe isekelwe ekungafani okuyisisekelo kwemishini.Ngoba ama-motor axutshwe nge-brush asebenzisa amabhulashi e-carbon angokoqobo acindezela i-commutator ejikelezayo ukuze adlulisele ugesi, isixhumi esibonakalayo se-brush-commutator sikhiqiza umsindo wokungqubuzana okuqhubekayo, umsindo we-arcing, kanye nokudlidliza okusakazeka ngaphakathi kwe-motor housing. Lo msindo uyingxenye yomklamo oxutshwe nge-brush futhi awukwazi ukususwa ngaphandle kokushintsha ubuchwepheshe be-motor.
Ama-motor e-DC angenamabhulashi asusa ngokuphelele isikhombimsebenzisi se-brush-commutator. Esikhundleni samabhulashi omshini, asebenzisa i-electronic commutation — isilawuli se-elekthronikhi sishintsha ugesi kuma-windings enjini ngokuvumelanisa nendawo ye-rotor, etholwa yizinzwa ze-Hall noma i-back-EMF sensing. Lokhu kushintsha kwe-elekthronikhi akwenzi ukuthintana komshini, akukho ukungqubuzana, futhi akukho ukugoqa, okuholela emazingeni omsindo aphansi kakhulu.
Imithombo yomsindo esele ku-motor engenamabhulashi yile: umsindo wokuthwala (ama-ball bearings asekela i-rotor shaft), umsindo we-electromagnetic (obangelwa amandla kazibuthe phakathi kwe-rotor ne-stator), kanye nomsindo we-windage (ukuphazamiseka komoya okubangelwa yi-rotor ejikelezayo). Ama-motor angenamabhulashi asezingeni eliphezulu anciphisa le mithombo ngokukhetha ngokunemba ama-bearings (ama-bearings avaliwe, agcotshwe ngaphambilini anamazinga aphansi omsindo), umklamo wesekethe ka-magnetic olungiselelwe (omagnets agwegwekile kanye nama-windings asakazwe anciphisa i-torque yokudonsa kanye nomsindo we-electromagnetic), kanye nomklamo we-rotor we-aerodynamic (izindawo ze-rotor ezibushelelezi ezinciphisa ukuphazamiseka komoya).
Kwemoto ye-DC engenamabhulashi engu-24V engu-60W efana nale esetshenziswa ku-Umsebenzisi womnyango oshelelayo we-YF150 ozenzakalelayo, umsindo ohlanganisiwe ovela kuyo yonke imithombo ngesivinini esijwayelekile sokusebenza u-42-48dB olinganiswa ngebanga lemitha eli-1 — ngaphakathi kwesilinganiso esingu-≤50dB esidingekayo ekusetshenzisweni kwendawo ethule.
Indlela Yokuhumusha Nokuqinisekisa Imininingwane Yezinga Lomsindo Wemoto
Izincazelo zezinga lomsindo zama-motor omnyango ozenzakalelayo zibalulekile kuphela uma zihambisana nezimo zokulinganisa.Ngoba injini efanayo ingakhiqiza i-35dB ngaphandle komthwalo kanye ne-55dB uma igcwele umthwalo., incazelo ethi “≤50dB” ngaphandle kokusho ibanga lokulinganisa, isimo somthwalo, isivinini semoto, kanye nomsindo ophansi ozungezile akuphelele ngokobuchwepheshe futhi kungase kudukise.
Iphrothokholi yokulinganisa ejwayelekile yomsindo wemoto isebenzisa imitha yomsindo elinganisiwe ebekwe ebangeni elichaziwe (ngokuvamile imitha eli-1) ukusuka kumoto, endaweni elawulwayo ye-acoustic (umsindo wangemuva ongaphansi kwama-30dB), lapho imoto isebenza ngomthwalo wayo olinganiselwe kanye nesivinini. Ukulinganisa kufanele kusebenzise isisindo se-A (dBA), esilinganisa impendulo yemvamisa yokuzwa komuntu futhi siyisisindo esijwayelekile esisetshenziswa emithethweni yomsindo emhlabeni jikelele.
Izindinganiso zokulinganisa izinga lomsindocacisa ukuthi izilinganiso zomsindo kumele zithathwe endaweni ekhululekile (akukho zindawo ezikhanyayo ngaphakathi kwamamitha ama-3) noma ekamelweni elingenamsindo ukuze kuqedwe iminikelo yomsindo obonakalayo. Empeleni, abakhiqizi abaningi bezicabha abazenzakalelayo balinganisa umsindo egumbini elingenamsindo obonakalayo (phansi elikhanyayo, izindonga ezimuncayo kanye nophahla) elilingisa isimo esifakiwe lapho injini ifakwe khona ngaphezu komnyango ovulekile.
Kubaphathi bezikhungo abachaza iminyango ezenzakalelayo yezinhlelo zokusebenza zezindawo ezithule, cela idatha yomsindo elandelayo kumenzi: (1) umsindo wemoto ngomthwalo olinganiselwe kanye nesivinini, olinganiswa ngemitha eli-1, (2) umsindo wesistimu yomnyango ophelele ohlanganisa indlela yokushayela kanye nokuhamba komnyango, olinganiswa ngemitha eli-1 ukusuka ekuvulekeni komnyango, kanye (3) idatha ye-spectrum yomsindo ekhombisa ukusatshalaliswa kwemvamisa (ukuhlonza noma yiziphi izingxenye zethoni ezingase zicasule kakhulu kunomsindo we-broadband ezingeni elifanayo).
Lokho Okusebenza Izinga Lomsindo Ezindaweni Ezihlukene Ezithule
Izinhlobo ezahlukene zezikhungo zinemikhawulo yomsindo ehlukene ngokusekelwe emsebenzini wazo kanye nokuzwela kwabantu abahlala kuzo.Ukuqonda lezi zindlela kuvumela abaphathi bezikhungo ukuthi bacacise izinga lomsindo wenjini elifanele kuhlelo ngalunye lokusebenza.kunokuba kusetshenziswe incazelo yobukhulu obufanayo engase icacise ngokweqile (ingeze izindleko) noma ingabi nkulu kangako (idale izikhalazo zomsindo).
Imitapo yolwazi yomphakathi: izinga lomsindo ozungezile elinconywayo lezindawo zokufunda lingu-35-40dB, kanti amakamelo okufundela adinga u-30-35dB. Ama-motor omnyango azenzakalelayo ekusetshenzisweni komtapo wolwazi akufanele anikele ngaphezu kuka-5dB ngaphezu komsindo wangemuva uma elinganiswa endaweni yokufunda eseduze, okuvame ukuhunyushwa ekuchazeni umsindo wemoto ongu-≤45dB kumitha eli-1.
Iminyuziyamu namagalari: izinga lomsindo ozungezile elinconywayo lingu-35-45dB kuye ngohlobo lwegalari. Amagalari athule (ubuciko besimanje, izindawo zokuzindla) adinga amazinga omsindo aphansi kunegalari esebenzisana noma amahholo okungena.Iziqondiso zokuchayeka komsindo ze-OSHAFaka isicelo kubasebenzi bemyuziyamu abavezwa umsindo weminyango amahora angu-8 ngosuku, okubeka umkhawulo wokuchayeka emsebenzini ongu-85dB we-TWA yamahora angu-8 (isilinganiso esilinganiselwe isikhathi).
Izibhedlela nezikhungo zokunakekelwa kwempilo: amakamelo eziguli adinga umsindo ozungezile ongaphansi kwama-35dB ebusuku nangaphansi kwama-40dB emini, ngokweziqondiso ze-WHO. Ama-motor eminyango azenzakalelayo emigwaqweni yesibhedlela eduze kwamakamelo eziguli kufanele acacise ukuthi isabelomali somsindo singakanani. Amakamelo okusebenza nezindawo ze-ICU zinezidingo eziqinile, ngokuvamile ezingaphansi kwama-30dB, ezidinga ama-motor eminyango anamazinga omsindo angaphansi kwama-40dB.
Amalabhorethri ocwaningo: amalabhorethri azwela umsindo (amakamelo okuhlola i-acoustic, amakamelo okuhlanza okukhiqiza ama-semiconductor, kanye namalabhorethri okukhanya) angadinga umsindo ozungezile ongaphansi kwama-25dB, osunduza imininingwane yemoto yomnyango ozenzakalelayo ibe yi-≤35dB — izinga elingafinyeleleka kuphela ngemiklamo yemoto engenamabhulashi ethule kakhulu esebenza ngesivinini esincishisiwe.
Indlela Umklamo Wesistimu Yomnyango Ozenzakalelayo Othinta Ngayo Umphumela Womsindo Ophelele
Injini iyisici esisodwa kuphela somsindo ophuma ohlelweni lomnyango oluzenzakalelayo.Ngoba indlela yokushayela, iqabunga lomnyango, kanye nesakhiwo sokufaka konke kunegalelo ezingeni lomsindo jikelele, incazelo yomsindo wezinga lesistimu kumele ibhekele yonke imithombo, hhayi injini kuphela.
Indlela yokushayela (ibhande, igiya, noma uchungechunge) idlulisela ukujikeleza kwenjini eqabungeni lomnyango. Ama-belt drive ayindlela ethule kakhulu ngoba ibhande lerabha noma le-polyurethane limunca ukudlidliza futhi linciphise ukudluliswa komsindo. Ama-gear drive anomsindo kakhulu ngenxa yomsindo we-gear mesh, ikakhulukazi lapho izinyo livame ukuhlangana khona. Ama-chain drive anomsindo kakhulu futhi awafanele ukusetshenziswa kwe-zone ethule. I-YF150 automatic sliding door operator isebenzisa uhlelo lwe-belt drive olufaka kuphela i-2-3dB kumsindo we-motor, okugcina umsindo wesistimu ungaphansi kwama-50dB.
Iqabunga lomnyango ngokwalo lidala umsindo ngokufuduka komoya (“umoya ocindezelwa umnyango ohambayo) kanye nokungqubuzana kwethrekhi (umsindo wama-hanger rollers ahamba eceleni kwesitimela). Umsindo wokufuduka komoya ulingana nesivinini somnyango kanye negebe phakathi kweqabunga lomnyango nohlaka — isivinini esihamba kancane kanye nezikhala eziqinile kukhiqiza umsindo omncane. Umsindo wokungqubuzana kwethrekhi uncike ezintweni ezisetshenziswayo (ama-nayiloni rollers athule kunama-steel rollers) kanye nesimo sobuso besitimela (i-rail ebushelelezi, egcotshwe ngamafutha ikhiqiza umsindo omncane kune-rail elukhuni noma eyomile).
Isakhiwo sokufaka singakhulisa noma sinciphise injini futhi sishayele umsindo. Injini efakwe ngqo ohlakeni lwensimbi oluqinile idlulisela ukudlidliza kahle, okungenzeka ikhulise umsindo ezindaweni zokufaka. Ukwengeza izikhonkwane zerabha zokuhlukanisa phakathi kwemoto nohlaka kunciphisa ukudluliselwa kokudlidliza ngo-10-20dB, okuhunyushwa ekunciphiseni komsindo okubonwayo okungu-50-75% endaweni yokulalela. Abaqhubi bezicabha ezizenzakalelayo zekhwalithi ephezulu bafaka izikhonkwane zokuhlukanisa ukudlidliza njengemishini ejwayelekile.
Indlela Yokuhlola Abahlinzeki Bezimoto Zeminyango Ezenzakalelayo Ngezicelo Ezibucayi Zomsindo
Ukukhetha umhlinzeki wezinhlelo zeminyango ezizenzakalelayo ezinhlelweni ezibucayi umsindo kudinga ukuqinisekiswa ngale kwencazelo yomsindo eshicilelwe.Ngoba ukusebenza komsindo kuthinteka yikhwalithi yokukhiqiza, ukunemba kokuhlanganiswa, kanye nokuvumelana kwezingxenye, ama-motor amabili anezincazelo ezifanayo ezivela kubahlinzeki abahlukene angakhiqiza amazinga omsindo ahlukene kakhulu ensimini.
Izindlela ezibalulekile zokuhlola umhlinzeki zifaka: imibiko yokuhlolwa komsindo evela kuma-laboratory aqinisekisiwe e-acoustic (hhayi idatha yokuhlolwa yangaphakathi yomkhiqizi kuphela), ukuhlolwa kwesampula endaweni yangempela yesikhungo (amazinga omsindo ayahlukahluka ngokwezimo zokufakwa), ukuqinisekiswa kokuvumelana komkhiqizo (cela idatha yokuhlolwa komsindo kusuka ezindaweni eziningi zokukhiqiza ukuqinisekisa ukufana), kanye nemigomo yewaranti ehlanganisa ukusebenza komsindo (umhlinzeki oqinisekisa ukusebenza komsindo iminyaka engu-2-5 ubonisa ukuzethemba ngomkhiqizo wakhe).
Imikhiqizo yomnyango ozenzakalelayo we-Beifanzenzelwe izinhlelo zokusebenza zezentengiselwano nezezikhungo lapho ukusebenza komsindo kubalulekile khona. Imoto ye-DC engenamabhulashi engu-24V 60W yemodeli ye-YF150 ichazwe ukusebenza okungu-≤50dB, enokulawula okuhlakaniphile kwe-microprocessor okulungisa isivinini semoto kanye namaphrofayili okusheshisa ukuze kuncishiswe umsindo ngesikhathi sokuvulwa nokuvalwa kwemijikelezo. Uhlelo lokulawula oluzifundela lona luvumelana nesisindo somnyango kanye nezimo zethrekhi ethile emijikelezweni yokuqala engu-50 yokusebenza, okwenza ngcono iphrofayili yesivinini ukuze kube nomsindo omncane ngenkathi kugcinwa isikhathi sokuvula esibekiwe.
Indlela Imikhuba Yokulungisa Ethinta Ngayo Ukusebenza Komsindo Wesikhathi Eside Kwezimoto Zomnyango Ezizenzakalelayo
Ukusebenza komsindo kuyawohloka ngokuhamba kwesikhathi uma uhlelo lomnyango oluzenzakalelayo lungagcinwa kahle.Ngoba ukuguguleka kwamabhere, ukucindezeleka kwebhande kuyashintsha, kanye nokungcola kwethrekhi kwandisa amazinga omsindo ngo-5-15dB esikhathini seminyaka engu-3-5, uhlelo lokulungisa oluvimbelayo lubalulekile ekugcineni imininingwane engu-≤50dB kuyo yonke impilo yesistimu.
Ukulungiswa kwanyanga zonke kwezicelo ezibucayi ngomsindo: ukuhlolwa okubonakalayo kwebhande ukuze kubonakale ukuthi liyaguga, liyaqhekeka, noma liyacwebezela; hlola ukuqina kwebhande (ibhande elikhululekile lishaya i-pulley, lidale umsindo ongasheshi); hlanza indawo yethrekhi ukuze ususe uthuli kanye nemfucumfucu ekhulisa umsindo we-roller; futhi uqinisekise ukuthi amabhawodi okufaka injini aqinile (amabhawodi akhululekile avumela ukwanda kokudlidliza).
Ukulungiswa kwekota: gcoba ama-track nama-roller bearings nge-lubricant esekelwe ku-silicone (gwema ama-lubricant asekelwe ku-petroleum adonsela uthuli); hlola ama-motor bearings ukuthi awadlali noma awaqinile (ukwehluleka kwe-bearings kusenesikhathi kubonakala njengomsindo wokugaya noma wokukhononda); bese uqinisekisa izinga lomsindo usebenzisa imitha yomsindo elinganisiwe ukuze uthole noma yikuphi ukukhukhuleka kusuka ekulinganisweni okuyisisekelo okuthathwe ekufakweni.
Ukulungiswa konyaka: ukulinganiswa komsindo okuphelele ngesivinini sokusebenza kanye nemithwalo eminingi; ukushintshwa kwebhande uma izinkomba zokuguguleka zibonisa ukuwohloka okukhulu; ukushintshwa kwamabhere enjini uma amazinga omsindo enyuke ngaphezu kwe-5dB kusukela ekuqaleni kokufakwa; kanye nokulungiswa kabusha kohlelo lokulawula ukuqinisekisa amaphrofayili esivinini afanele kakhulu omsindo omncane.
