Ukufinyelela ukulawulwa koketshezi okunembe kakhulu kubalulekile ezinhlelweni zesimanje zezokwelapha, zelebhu, kanye nezezimboni. Konjiniyela kanye nabaphathi bemikhiqizo, akwanele ukukhetha ama-micro-pump; Isihluthulelo ukwenza ngcono ukusebenza kwawo ukuze kuhlangatshezwane nezidingo zesistimu eziqinile. Lo mhlahlandlela uzokwethula ezinye izindlela ezilula nezisebenzayo zokulungisa.amaphampu amancane e-DC angu-12 voltukuze kube nokunemba okuphezulu.

Izinkinga ezimbili eziyinhloko zokulawula okunembile okuphezulu

Ekulawuleni uketshezi, ukunemba okuphezulu, ikakhulukazi kusukela ekudlulisweni kwamandla okuphezulu kuya ekuzinzeni okuphezulu.

1. Ukuqina kokugeleza: Isihluthulelo ukuqina, hhayi usayizi

Isidingo esiyinhloko sohlelo lokunemba okuphezulu akusikho izinga lokugeleza eliphezulu, kodwa izinga lokugeleza elizinzile kakhulu. Izilinganiso ezibalulekile ukuphindaphindwa kokugeleza (ukuthi umkhiqizo ngamunye useduze kangakanani nowokugcina) kanye nokushaya kwenhliziyo (ukuguquguquka okuncane kwesilinganiso sokugeleza). Izinhlelo zokunemba okuphezulu zidinga ukuthi ukugeleza kwe-aiphampu encane engu-12 V DCihlala ingaguquguquki ngokuhamba kwesikhathi kanye nesikhathi somjikelezo.

2 Ukufanisa ikhanda: Thola iphuzu elifanele lokulinganisela

Inhloko (noma ikhanda) ibhekisela ekucindezelweni okungakhiqizwa yiphampu. Lo mfutho kumele uhambisane kahle nokumelana (noma ikhanda lesistimu) okukhiqizwa amapayipi, izihlungi, namavalvu ohlelweni. Ukukhetha amaphampu anelifti elikhulu kakhulu kudla amandla futhi kubangele ukuguguleka okungadingekile, kanti ilifti elincane kakhulu lisho ukuthi iphampu ayikwazi ukunqoba ukumelana kwesistimu. Umgomo ukutholaiphampu yamanzi encane engu-12Vijika layo lokusebenza lihambisana kahle nejika lokumelana lesistimu.

Umklamo wephampu: Yenza iphampu ibe nobuhlakani obuningi

Ukwenziwa ngcono kuqala ngephampu uqobo. Ubuchwepheshe besimanje bephampu encane buhlinzeka ngezindlela ezahlukahlukene zokuthuthukisa ukunemba.

1. yamukela injini ye-DC (BLDC) engenamabhulashi: isihluthulelo sokufeza ukulawulwa kwesivinini se-elekthronikhi

Injini yebhulashi yendabuko inezinkinga zokungqubuzana nokuguguleka, ngakho-ke kunzima ukufeza ukulawulwa kwesivinini okunembile. Ngokuphambene nalokho, ubuchwepheshe bephampu ye-DC engenamabhulashi buvumela ukulawulwa kwesivinini se-elekthronikhi okunembile (ngokuvamile ngamasignali e-PWM). Lokhu kulawulwa okunembile kuhumushela ngqo esilinganisweni sokugeleza esizinzile kakhulu, okwenza iphampu ye-DC engenamabhulashi ibe yisisekelo sanoma yiluphi uhlelo olunembe kakhulu.

2. Lungiselela isakhiwo sekhanda lephampu: Susa "ukujitha" kokugeleza

Ukuze kuncishiswe ukugeleza okungokwemvelo "kwe-jitter" (i-pulsation) okuvamile kumaphampu okuhambisa umoya amahle, abakhiqizi basebenzise amasu ahlukahlukene. Lokhu kufaka phakathi ukusetshenziswa kwamaphampu anamakhanda amaningi, njengephampu ye-diaphragm enamakhanda amabili, noma ukuhlanganiswa kwama-dampers adonsa umoya endaweni yokuphuma kwephampu.Amaphampu okuzilungiselela wona angu-12V, ukunciphisa ukushaya kwenhliziyo kubalulekile ukuqinisekisa ukulethwa koketshezi okubushelelezi nokunembile, ikakhulukazi lapho kubhekene nokugeleza okuncane.

Izixazululo zokuhlanganisa uhlelo: yenza uhlelo luvumelane nezimo

Ngisho nephampu engcono kakhulu nayo idinga ukubambisana ukuze isebenzise uhlelo oluhlakaniphile, singakufeza ngempela ukunemba okuphezulu.

1. Ukubalwa okunembile kokumelana kwesistimu: Gwema ukuqagela

Ngaphambi kokukhetha iphampu encane ye-12V DC, unjiniyela kumele abale ngokunembile ukwehla kwengcindezi kwazo zonke izingxenye (amapayipi, izixhumi, izihlungi). Lokhu kubalwa kuqinisekisa ukuthi ikhanda lephampu elikhethiwe lihlangabezana ngqo nezidingo zohlelo lokusebenza, ngaleyo ndlela kugwenywe ukumoshwa kwamandla kanye nokwehluleka kwephampu ngaphambi kwesikhathi.

2. Sebenzisa ukulawula okuvaliwe: umsebenzi "wokulungisa okuzenzakalelayo"

Ukusebenzisa ukunemba okuguquguqukayo kuyindlela ephumelela kakhulu yokulawula i-closed loop. Lokhu kudingeka kube ekuphumeni kokugeleza kokufakwa kwephampu noma inzwa yokucindezela. Izinzwa zibuyisela idatha yesikhathi sangempela kuma-actuator kagesi ephampu, okwenza iphampu ikwazi ukulungisa ngokuzenzakalelayo isivinini sayo (nge-motor ye-DC engenamabhulashi) ukuze igcine izinga lokugeleza eliqondiwe ngisho noma ukumelana kwesistimu kushintsha.

Isincomo sesixazululo sobungcweti

Ukulawulwa koketshezi okunembe kakhulu kudinga umlingani oqonda kokubili imishini yokupompa kanye nezilawuli ze-elekthronikhi. I-Pincheng Motor igxile ekuhlinzekeni ngokunemba okuphezuluiphampu yamanzi encaneizixazululo. Umkhiqizo wayo oyinhloko uyimoduli yokulawula ye-DC engenamabhulashi evala iluphu evumela umkhiqizo wayo omncane wephampu ye-DC engu-12 volt ukuthi ufinyelele ukuphindaphindeka kokugeleza okungu-±1%. I-Pincheng Motor inikeza amakhanda ephampu enziwe ngokwezifiso kanye nezixazululo zokushayela ezihlanganisiwe ukusiza onjiniyela ukuthi bafanise kahle ama-curve okusebenza kwephampu nezidingo zesistimu, okwenza kube ngumlingani ofanele wokulawula uketshezi olunembile kakhulu.

isiphetho

Ukuthuthukisa amaphampu amancane ukuze kulawulwe ngokunemba okuphezulu kuyinqubo ehlelekile ehlanganisa ukwakheka kwephampu okuthuthukisiwe nokuhlanganiswa kohlelo okuhlakaniphile. Ngokugxila ekulawuleni isivinini kanye nempendulo evaliwe yama-motor e-DC angenamabhulashi (i-BLDCS), ungaguqula iphampu yamanzi encane engu-12V ejwayelekile ibe yingxenye yokulawula uketshezi ethembekile nenembile kakhulu.
