Ukusebenza Komshini Wokubhoboza
I-WS7040-24-V200 blower ingafinyelela ukuhamba komoya okuphezulu okungu-22m3/h ngokucindezela okungu-0 kpa kanye nokucindezela okungaguquki okungu-6.8kpa. Inamandla omoya aphezulu okukhipha uma le blower isebenza ngokumelana okungu-3kPa uma sibeka i-100% PWM. Isebenza kahle kakhulu uma le blower isebenza ngokumelana okungu-5.5kPa uma sibeka i-100% PWM. Okunye ukusebenza kwe-load point kubhekisela ku-PQ curve engezansi:
Inzuzo ye-DC Brushless Blower
(1) I-WS7040-24-V200 blower inama-motor angenamabhulashi kanye nama-bearings e-NMB ngaphakathi okubonisa isikhathi eside kakhulu sokuphila; i-MTTF yale blower ingafinyelela emahoreni angaphezu kuka-20,000 ekushiseni kwemvelo okungu-20 degrees C.
(2) Lo mshini wokufutha awudingi ukulungiswa
(3) Le blower eqhutshwa yisilawuli semoto esingenamabhulashi inemisebenzi eminingi yokulawula ehlukene njengokulawula isivinini, ukuphuma kwe-speed pulse, ukusheshisa okusheshayo, ukubopha njll. ingalawulwa kalula ngomshini ohlakaniphile nemishini.
(4) Uma iqhutshwa ngumshayeli wemoto engenamabhulashi, i-blower izoba nokuvikelwa kwe-over current, i-voltage engaphansi/ngaphezulu, kanye ne-stall.
Izicelo
Lo mshini wokufaka umoya ungasetshenziswa kabanzi emshinini wokufaka umoya, emshinini we-CPAP, esiteshini sokulungisa kabusha i-SMD soldering.
Indlela Yokusebenzisa I-Blower Ngokufanele
Imibuzo Evame Ukubuzwa
U: Ikhasimende: Ngingayisebenzisa yini le blower kudivayisi yezokwelapha?
A: Yebo, lesi esinye sezinto ezisetshenziswa enkampanini yethu ezingasetshenziswa ku-Cpap kanye ne-ventilator.
Q: Uyini umfutho womoya ophezulu?
A: Njengoba kuboniswe emdwebeni, umfutho womoya ophezulu kakhulu ungu-6.5 Kpa.
Uma kuqhathaniswa nemoto ye-DC kanye nemoto engahambisani, izici zobuchwepheshe ezibalulekile zemoto ye-Brushless DC yilezi:
1. Izici zokusebenza kwemoto ye-DC zitholakala ngokulawulwa kwe-elekthronikhi. Inokulawulwa okungcono kanye nobubanzi besivinini.
2. Kudingeka ulwazi lwempendulo yesikhundla se-rotor kanye nomshayeli we-inverter we-electronic multiphase.
3. Ngokuyisisekelo, injini ye-AC ingasebenza ngesivinini esikhulu ngaphandle kwenhlansi nokuklwebheka kwebhulashi kanye ne-commutator. Inokuthembeka okuphezulu, isebenza isikhathi eside futhi ayidingi ukulungiswa.
4. Imoto ye-DC engenamabhulashi inamandla aphezulu, ayinawo ukulahleka kwe-rotor nokushisa, kanye nokusebenza kahle okuphezulu: uma kuqhathaniswa nedatha, ukusebenza kahle kwemoto engu-7.5 kW engahambisani ne-asynchronous kungu-86.4%, kanti ukusebenza kahle kwemoto ye-DC engenamabhulashi efanayo kungafinyelela ku-92.4%.
5.Kumele kube nezingxenye zokulawula ze-elekthronikhi, izindleko zizonke ziphakeme kunemoto ye-DC.
Kunezinhlobo ezimbili zama-motor ezisetshenziswa kakhulu ohlelweni lwe-AC: i-induction motor kanye ne-permanent magnet synchronous motor. I-permanent magnet synchronous motor ingahlukaniswa ibe yi-sinusoidal back EMF permanent magnet synchronous motor (PMSM) kanye ne-square wave back EMF brushless DC motor (BLDCM) ngokwemigomo yokusebenza ehlukene. Ukuze imodi yabo yamanje yokushayela kanye neyokulawula ihluke.
I-EMF yangemuva yemoto ye-sinusoidal permanent magnet synchronous yi-sinusoidal. Ukuze imoto ikhiqize i-torque ebushelelezi, ugesi ogeleza ngokugoqa imoto kumele ube yi-sinusoidal. Ngakho-ke, isignali yesikhundla se-rotor eqhubekayo kumele yaziwe, futhi i-inverter inganikeza ugesi noma ugesi we-sinusoidal kumoto. Ngakho-ke, i-PMSM idinga ukusebenzisa ugesi noma ugesi ophezulu. Isixazululo se-encoder yesikhundla noma i-resolver naso siyinkimbinkimbi kakhulu.
I-BLDCM ayidingi inzwa yesikhundla esinesinqumo esiphezulu, idivayisi yempendulo ilula, futhi i-algorithm yokulawula ilula kakhulu. Ngaphezu kwalokho, insimu yamagnetic yegebe lomoya ye-BLDCM trapezoidal wave isebenza kahle kakhulu kuneye-PMSM sinusoidal wave, futhi ubukhulu bamandla be-BLDCM buphakeme kunobe-PMSM. Ngakho-ke, ukusetshenziswa nokucwaninga kwe-permanent magnet brushless DC motor kuye kwathola ukunakwa okwengeziwe.
