Musi waZvita 14, 2021, ndeupi musiyano uripo pakatikufefetedza motauye mota yakajairika?
(1) , Akasiyana dhizaini masisitimu:
1. Iyo yekupisa yekupisa system yakasiyana: feni yekupisa kupisa mune yakajairika fan uye musimboti weiyo centrifugal fan inoshandisa mutsara wakafanana, nepo maviri ari mumhepo yekufemesa akaparadzaniswa.Naizvozvo, kana iyo frequency shanduko yeyakajairika fan yakadzikira, inopiswa nekuda kwekupisa.
2. Electromagnetic dhizaini yakasiyana: kune akajairwa mota, akakosha tekinoroji paramita akatariswa muchirongwa chekugadzirisa zvakare kuwandisa, maitiro ekushanda, kushanda kwakanyanya uye masimba masimba.Imotokari yemhepo, nokuti iyo yakakosha slip rate inversely proportional to frequency power, inogona kutangwa zvakananga kana iyo yakakosha slip rate inosvika 1. Nokudaro, simba rekutakura uye maitiro ekushanda haafaniri kuonekwa zvakanyanya.Dambudziko rinogadziriswa ndere nzira yekuvandudza kuchinjika kwemota kune non sine wave simba rekupa.
3. Nekuda kwekuti mota yekufefetera ine high-frequency electromagnetic field, giredhi remoto retardant rakakwirira kudarika remotawo zvayo.Muchidimbu, mota yakajairika haigone kufambiswa nema frequency converter, asi kutaura zvazviri, kuchengetedza midziyo, mota yakajairika inoshandiswa kutsiva inochinja-frequency mota munzvimbo zhinji panodiwa shanduko yekumhanya, asi iyo yekumhanyisa shanduko chaiyo yeyakajairwa mota. haina kukwirira.In centrifugal fan Izvi zvinowanzoitwa mukushandurwa kwekuchengetedza simba kwepombi yemvura ye centrifugal.
4. Yakawedzerwa electromagnetic mutoro: iyo inobuda kuramba yeyakajairika mota yakavakirwa pane inflection point yemagnetic saturation.Kana ikashandiswa sefrequency kutendeuka, zviri nyore kuti zvizadziswe, zvichikonzera kukwirisa kwazvino.Nepo iyo mota yekufemesa ichiwedzera iyo electromagnetic mutoro mune dhizaini dhizaini, kuitira kuti iyo magineti yedunhu haisi nyore kuguta.Chimwezve ndechekuti ma frequency motors anowanzo kupatsanurwa kuita anogara ari torque akakosha mota, akakosha mota ane kumhanya kumisa michina uye epakati frequency mota ane mhinduro vector control.
(2) Misiyano pakuyera:
1. Muchokwadi, iyo yakabuda waveform ye frequency converter is sinusoidal wave.Pamusoro peiyo yakakosha wave, inosanganisirawo mutakuri chiratidzo.Iyo inotakura data siginecha frequency yakakwira zvakanyanya kupfuura iyo yakakosha wave, uye iri square wave data siginecha, kusanganisira akawanda akakwira-odha harmonics.Kune iyo yekuona sisitimu, yakakwira sampling frequency uye network bandwidth inotsanangurwa.
2. Munharaunda yefrequency converter power supply system, marudzi ose e-high-frequency interferences ari kwese kwese, uye chiratidzo chekuvhiringidza chakasimba kudarika icho chiri mumagetsi frequency environment, iyo inotaura kuti hurongwa hwekuona hune simba rakasimba reunyanzvi hwekuenderana kwe electromagnetic.
3. Chinhu chepamusoro chekufambisa mhepo yekufambisa inowanzokwira.Izvo zvigadziro zvinotariswa mumhando yezviridzwa zvakajairika.Kune iyo frequency yekushandura yekuona sisitimu, inodiwa kuve nepamusoro chaiyo yekuyera kugona kwepeak factor.
