Kugona kudzora mvura nemazvo kwakakosha muzvirongwa zvemazuva ano zvekurapa, marabhoritari, uye zvemaindasitiri. Kune mainjiniya nevatariri vezvigadzirwa, hazvina kukwana kusarudza ma micro-pomps; Chinokosha ndechekugadzirisa mashandiro ayo kuti ienderane nezvinodiwa zvesystem yakaoma. Gwaro iri richapa dzimwe nzira dziri nyore uye dzinoshanda dzekugadzirisa.pombi diki dzeDC dze12 voltkuti zvive zvakanyatsojeka.

Nyaya mbiri huru dzekudzora kwakanyatsojeka

Mukutonga kwemvura, kunyatsojeka kwakanyanya, kunyanya kubva pakuchinjisa simba guru kusvika pakugadzikana kwakanyanya.

1. Kugadzikana kwemvura: Chinhu chikuru kugadzikana, kwete saizi

Chinonyanya kukosha pakushandisa system yekunyatsojeka hakusi kuyerera kwakanyanya, asi kuyerera kwakasimba. Zviyero zvikuru ndezvekuti kuyerera kwemvura kudzokororwa sei (kuti kubuda kwemvura kwava pedyo zvakadii nekwekupedzisira) uye kuputika kwemvura (kuchinja-chinja kudiki kwekufamba kwemvura). Masisitimu ekunyatsojeka kwemvura anoda kuti kuyerera kwemvura kuenderere mberi.pombi diki ye12 V DCinoramba iripo nekufamba kwenguva uye nguva yekutenderera.

2 Kufananidza musoro: Tsvaga poindi yakakwana yekuyera

Musoro (kana musoro) zvinoreva kumanikidzwa kunogona kugadzirwa nepombi. Kumanikidzwa uku kunofanira kuenderana zvakakwana nekudzvinyirirwa (kana musoro wesystem) kunogadzirwa nemapaipi, mafirita, nemavharuvhu ari musystem. Kusarudza mapombi ane lift yakakura zvakanyanya kunopedza simba uye kunokonzera kusakara kusingakoshi, nepo lift diki kwazvo zvichireva kuti pombi haigone kukunda kudzvinyirirwa kwesystem. Chinangwa ndechekuwanapombi yemvura diki ye12Vine curve yekushanda inoenderana zvakakwana necurve yekudzivirira yesystem.

Dhizaini yepombi: Ita kuti pombi ive yakangwara

Kugadzirisa kunotanga nepombi pachayo. Tekinoroji yemazuva ano ye micropomp inopa nzira dzakasiyana-siyana dzekuvandudza kururama.

1. Inoshandisa mota yeDC (BLDC) isina brushless: kiyi yekuzadzisa kurongeka kwekumhanya kwemagetsi

Mota yemabhurashi yechinyakare ine matambudziko ekukweshana uye kupfeka, saka zvakaoma kuwana mutemo chaiwo wekumhanya. Kusiyana neizvi, tekinoroji yepombi yeDC isina brush inogonesa mutemo chaiwo wekumhanya kwemagetsi (kazhinji kuburikidza nemasaini ePWM). Kudzora uku kwakanyatsojeka kunoshandura zvakananga mukufamba kwakasimba, zvichiita kuti pombi yeDC isina brush ive hwaro hwechero sisitimu yakanyatsojeka.

2. Gadzirisa chimiro chemusoro wepombi: Bvisa "kuyerera" kwemvura

Kuti vaderedze "kuvhunduka" kunoitika mumuviri (pulsation) kunowanzoitika mumapombi ekufambisa zvakanaka, vagadziri vakashandisa nzira dzakasiyana-siyana. Izvi zvinosanganisira kushandisa mapombi ane misoro yakawanda, akadai semapombi ane misoro miviri, kana kubatanidzwa kwema pulsating dampers panobuda pombi.Pombi dzinozvigadzirira dze 12V, kuderedza kurova kwemoyo kwakakosha kuti mvura isvike zvakanaka uye nemazvo, kunyanya kana paine kuyerera kudiki.

Mhinduro dzekubatanidza sisitimu: ita kuti sisitimu igone kuchinja

Kunyangwe pombi yakanakisisa inofanirawo kushanda pamwe chete kuti ishandise sisitimu yakangwara, tinogona here kuwana kunyatsojeka kwakanyanya?

1. Kuverenga kwakarurama kwekudzivirira kwesystem: Dzivisa kufungidzira

Usati wasarudza pombi diki ye12V DC, mainjiniya anofanira kuverenga nemazvo kuderera kwekumanikidzwa kwezvinhu zvese (mapaipi, zvinobatanidza, mafirita). Kuverenga uku kunoita kuti musoro wepombi wakasarudzwa unyatsoenderana nezvinodiwa zvekushandisa, nokudaro uchidzivirira kutambisa simba uye kutadza kushanda kwepombi nguva isati yakwana.

2. Shandisa simba rekudzora rakavharika: basa rekuti "kugadzirisa otomatiki"

Kuti ushandise dynamic accuracy ndiyo nzira inoshanda zvikuru yekudzora closed loop. Izvi zvinofanirwa kunge zviri mu output yekuisa pombi flow kana pressure sensor. MaSensor anodzosera data renguva chaiyo kuma actuator epombi, zvichiita kuti pombi ikwanise kugadzirisa otomatiki kumhanya kwayo (kuburikidza nemota yeDC isina brushless) kuti irambe iine target flow rate kunyangwe system resistance ichichinja.

Kurudziro yenyanzvi yekugadzirisa mhinduro

Kudzora mvura nemazvo kunoda mumwe munhu anonzwisisa mashandiro epombi uye mashandisirwo emagetsi. Pincheng Motor inotarisa pakupa kunyatsojeka kwemvura.pombi yemvura dikimhinduro. Chigadzirwa chayo chikuru imodhi yekudzora isina brushless DC closed-loop inoita kuti chigadzirwa chayo chidiki chepombi yeDC ye12 volts chikwanise kudzokorora kuyerera kwe±1%. Pincheng Motor inopa misoro yepombi yakagadzirirwa uye mhinduro dzedhiraivha dzakabatanidzwa kubatsira mainjiniya kuenzanisa zvakakwana macurve ekushanda kwepombi nezvinodiwa zvesisitimu, zvichiita kuti ive mubatsiri akakodzera wekutonga kwemvura kwakanyatsojeka.

mhedziso

Kugadzirisa mapombi madiki kuti akwanise kudzora zvine hungwaru inzira yakarongeka inosanganisa dhizaini yepombi yepamusoro nekubatanidzwa kwehurongwa hwakangwara. Nekutarisa pakudzora kumhanya uye mhinduro yekuvhara kweloop yemota dzeDC dzisina mabhurashi (BLDCS), unogona kushandura pombi yemvura ye12V micro yakajairwa kuita chikamu chekudzora mvura chakavimbika uye chakanyatsojeka.
