Musoro: Kusunungura simba rema frequency converters: kuwedzera kushanda zvakanaka uye kuchengetedza mari
Ndima yekutanga: Nhanganyaya kuchinoshandura mafrequency
Chinoshandura ma frequency, chinozivikanwawo sedhiraivha yefrequency inoshanduka (VFD), chishandiso chekushandura simba chinodzora nekudzora kumhanya kwemota yemagetsi. Nekudzora mafrequency nevoltage zvinopihwa kumota, chinoshandura mafrequency chinogona kudzora kumhanya netorque yemota nemazvo. Midziyo iyi inoshandiswa zvakasiyana-siyana inoshandiswa mumaindasitiri akasiyana-siyana, kubva mukugadzira uye masisitimu eHVAC kusvika kusimba rinodzokororwa uye kutakura. Mublog rino, tichaongorora kugona kwevanoshandura mafrequency, kukurukura mabhenefiti avo, uye kujekesa basa ravo rakakosha mukuvandudza kushanda zvakanaka uye kuchengetedza mari.
Ndima yechipiri: Nheyo yekushandachinoshandura mafrequency
Chinoshandura mafrequency chinoshandura mafrequency akagadzika uye voltage yemagetsi ekupinda kuita mafrequency anogadziriswa uye voltage, zvichigadzira shanduko yefrequency yakakodzera kutyaira mhando dzakasiyana dzemota. Nekugadzirisa mafrequency ekupinda, chinoshandura mafrequency chinogona kudzora kumhanya kwemota. Inopinda alternating current (AC) inotanga yagadziriswa uchishandisa rectifier yozoshandurwa kuita direct current (DC). Dunhu re inverter rinozoshandiswa kushandura DC voltage kudzokera kuAC voltage ine adjustable frequency uye voltage. Iyi adjustable AC output inoiswa mumota, zvichiita kuti ikwanise kudzora kumhanya kwayo uye torque.
Ndima 3: Mabhenefiti makuru ekushandura ma frequency
Vashanduri vemafrequencyZvinopa mabhenefiti akawanda mumashandisirwo akasiyana-siyana emaindasitiri. Chekutanga, zvinobvumira mota kumhanya nekumhanya kwakanyanya pane kuramba ichishanda nesimba rakazara, zvichikonzera kuchengetedza simba zvakanyanya. Nekugadzirisa kumhanya kuti kuenderane nezvinodiwa zvemutoro chaiwo,ma frequency converterszvinogona kuderedza kushandiswa kwesimba, nokudaro zvichideredza mabhiri emagetsi. Chechipiri, zvinovandudza kudzora mashandiro nekupa mitemo chaiyo yekumhanya, nokudaro zvichiwedzera kugadzirwa uye zvichideredza kusakara kwemidziyo. Pamusoro pezvo, frequency converter inopa mabasa ekutanga nekumira zvinyoro nyoro, nokudaro ichideredza kushushikana kwemuchina uye kuwedzera hupenyu hwebasa remota nemichina. Pamusoro pezvo, frequency converters dzinobvisa kudiwa kwezvinodzora zvemuchina zvakaita sezvinodzora ma throttles uye dampers, zvichiita kuti zvive nyore kugadzirisa nekugadzirisa system.
Ndima 4: Kushandiswa kwechinoshandura mafrequency
Ma frequency converters anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana. Mukugadzira, anoshandiswa mumichina yakaita sema conveyors, mapombi uye ma compressor kuti awedzere kushandiswa kwesimba uye aite kuti mutsetse wekugadzira uve nyore. Variable speed drives chikamu chakakosha chehurongwa hwemazuva ano hweHVAC, zvichibvumira kudzora kwakanyatsojeka kwema ventilators, ma chillers nemapombi kuti vawedzere kunyaradzwa uye kushanda zvakanaka kwesimba. Muhurongwa hwesimba rinogona kudzokororwazve senge ma wind turbines nema solar panels,ma frequency convertersvanoita basa rakakosha mukushandura simba reDC rinoshanduka-shanduka rinogadzirwa kuita simba reAC rinoenderana negrid. Pamusoro pezvo, ma frequency converters anoshandiswa mumasystem emagetsi ekufambisa mota kudzora kumhanya kwemota uye torque, zvichiita kuti simba rishandiswe zvakanaka uye kuwedzera hupenyu hwebhatiri.
Ndima 5: Zvinhu zvekufunga nezvazvo pakusarudza inverter
Pakusarudzachinoshandura mafrequency, pane zvinhu zvakati wandei zvekufunga nezvazvo. Chekutanga, chiyero chesimba chinofanira kuenderana nezvinodiwa nemota kuti ive nechokwadi chekuti inoenderana. Voltage uye frequency range ye inverter inofanirawo kuenderana nemagetsi aripo. Pamusoro pezvo, nzira dzekudzora, dzakadai sekudzora voltage vector kana direct torque control, dzinofanira kuongororwa zvichienderana nekushanda kwemota kunodiwa. Zvakakosha kuona zvinhu zvekudzivirira zvinodiwa, zvakaita sekudzivirira overcurrent uye overvoltage, kudzivirira mota ne inverter kubva mukukuvadzwa kunogona kuitika. Chekupedzisira, nyore kuisa, nyore kushandisa uye kuwanikwa kwemabasa ekutsigira mugadziri zvakakoshawo.
Ndima 6: Kudzoka kubva pakudyara uye kuchengetedza mari
Nekufamba kwenguva, mari yekudyara muchinoshandura mafrequencyzvinogona kukonzera kuchengetedza mari yakawanda uye kudzoka kunokwezva pakudyara (ROI).Vashanduri vemafrequencyinobatsira kuderedza mari yekushandisa kwenguva refu nekuderedza kushandiswa kwesimba, kugadzirisa mashandiro esystem uye kuwedzera hupenyu hwemidziyo. Pamusoro pezvo, kudzora mashandiro kwakawedzerwa kunopihwa nema frequency converters kunovimbisa kuwedzera kwekubudirira, nokudaro zvichiwedzera kubuda uye purofiti. Pakuongorora kudzoka kwemari inoiswa, zvakakosha kufunga nezvemitengo yekutanga yekutenga nekuisa, pamwe chete nekuchengetedzwa kwesimba kunotarisirwa uye purofiti yekubudirira muhupenyu hwe frequency converter system.
Ndima 7: Mhedziso
Muchidimbu,ma frequency converterschishandiso chakakosha chinounza kushanda zvakanaka, kuchinjika uye kuchengetedza mari kumaindasitiri akasiyana-siyana. Nekudzora kumhanya kwemota uye torque, zvinogonesa kugadzirisa simba, kudzora mashandiro uye kuwedzera hupenyu hwemidziyo. Nemashandisirwo akasiyana-siyana kubva mukugadzira uye masisitimu eHVAC kusvika kune simba rinogona kudzokororwa uye kutakurwa,ma frequency converterszvave chinhu chakakosha muhurongwa hwemazuva ano hwetekinoroji. Kunyatsofunga uye kusarudzwa kwemushanduri wema frequency akakodzera zvichienderana nezvinodiwa nezvinodiwa zvinogona kukonzera kuchengetedza mari yakawanda, kuwedzera kugadzirwa uye nzira inochengetedza kushandiswa kwesimba. Kushandisa tekinoroji iyi ndiyo chete nzira yekuvandudza mashandiro, kuderedza mari, uye kugadzira ramangwana rakanaka.
