DC Pumps Are Better Than Ac Pumps in Solar Pumping Systems

Izinkuni ze-DC Zinjalo Ngaphezulu Kwezinkuni ze-AC Ezindaweni Zokupompa Kwesolwandle

Isicelo sompompo wamanzi wesolwazi ngumqondo wempompo wamanzi wesolwazi, ngakho ukhetha impompo yamanzi ethembekile kungukhetho olungelakho ekwenzeni isistimu esinamandla.

Kunezinye izinhlobo ezimbili zemibhobho yamanzi yesolwazi ezindaweni: izimpawu zemvula AC kanye nezimpawu zemvula DC.

Izinkuni zezemvula zezemvula zisebenzisa i-DC motor ekhethekile okusebenza nezinkuni zezemvula njengasezinkampani zezemvula noma izibhobho, ngakho akukho okudingayo.

Inqubo yokupompa i-AC yasiza i-motor ye-AC ukuguqula i-nzuzo ye-DC kusuka kwi-paneli ye-solar ukuya ku-nzuzo ye-AC ngokushesha nge-inverter ye-solar pump.

Kunjalo, yini okuhle, i-AC pump noma i-DC pump?

In practice, we usually use DC pumps in low power capacity systems below 5kW, but there are a few factors to consider when choosing one over the other, as they each have their pros and cons.

Isilinganiso

Ngeshwa, i-DC pump iyimpumelelo kunayo i-AC pump futhi iyadinga amapaneli amakhulu amaningi ezokwenza, kodwa iyisikhathi esingakanani ukulawula emadolobheni ngoba iyadinga isikhungo eshibhile sokwenza futhi ngeke uyilawule ekupheleni kwesikhathi, okuyinto kungaba yisabani esingakanani kubonisa ukuthi isilinganiso siyisikhathi esiningi kwe-AC pump.

Izindleko Zemisebenzi

Ngokwezinsizakalo zobudlelwano, izitshalo zezamanzi eziluhlaza zase-DC zisebenzisa izinkuni zemoto ezimhlophe, ezinamandla okwengeziwe, kodwa izitshalo zezamanzi eziluhlaza zase-AC zisebenzisa izinkuni zemoto zezaliminamu/nemoto zemikhonkothi ngezindlela ezinamandla.

Ingqikithi

Ngokwezici zokugcina, iphampu ye-DC iyaphuma kancane kanye nokulula ngoba iyisebenzisa i-motor ye-BLDC eyinhloko yemvelo yokwenziwa, ngesikhathi iphampu ye-AC iyisebenzisa i-technology yemoto yesikhathi esidlule, futhi inzuzo yephampu ye-AC iyavutha ngesikhathi.

Kunzima manje ukuthi ukusebenzisa iphampu ye-DC kungcono kakhulu kunokusebenzisa iphampu ye-AC.

Izinhlobo zezinto zezilwane zezilwane zase-DC solar pumping.

Indawo yomthombo wezinkanyezi zesolwazi ye-D.C. iyinhloko yomqulu wezinkanyezi zesolwazi, ikhontrola, kanye nomthombo wezamanzi we-D.C. Okuhamba kakhulu kuyinto ikhontrola ye-D.C., enezinqubo ezingu-4 ezinhle kakhulu.

Thinta i-voltage ye-DC yokulawula i-pointi yezinkampani ezingaphezulu (MPPT) ukuze uhambele i-pump ngokwesekela.

Ukuqala futhi ukuphinda ukususa iphampu ngokwesibonelo.

Q. Qala enkampani ngeqembu elula.

Nika izinhlamvu eziningi njengoba ukukhathazeka kwangaphandle, ukukhathazeka okwesikhathi, ukukhathazeka okuphakathi, ukukhathazeka okuphansi, futhi ukukhathazeka okuphakathi.

I-DC controller inamaphepha okubonisa izimpendulo zasemoyeni zezinkampani, ivolthi, ukudla kwamandla, nokwengeziweko kwesikhwele.

Okokuqala, izinkomba ezilandelayo zizungeza izinzuzo phakathi kwemibhede yamanzi ase-AC ne-DC kanye nezinto ezitholakala kwi-system yamanzi ase-DC. Uma ufuna ukuthenga izitshalo zasezulwini, sicela uxhumane nathi.
