Ukufikelela kulawulo lolwelo oluchanekileyo kakhulu kubalulekile kwiinkqubo zanamhlanje zonyango, elebhu, kunye nezoshishino. Kwiinjineli kunye nabaphathi beemveliso, akwanelanga ukukhetha ii-micro-pumps; Isitshixo kukuphucula ukusebenza kwayo ukuze ihlangabezane neemfuno zenkqubo ezingqongqo. Esi sikhokelo siza kwazisa ezinye iindlela ezilula nezisebenzayo zokulungisa.iimpompo zeDC ezincinci ze-12 voltukuze kube nokuchaneka okuphezulu.

Imiba emibini ephambili yolawulo oluchanekileyo

Kulawulo lolwelo, ukuchaneka okuphezulu, ikakhulu ukusuka ekudlulisweni kwamandla aphezulu ukuya ekuzinzeni okuphezulu.

1. Uzinzo lokuhamba kwamanzi: Isitshixo kukuzinza, hayi ubungakanani

Eyona mfuneko iphambili yenkqubo yokuchaneka okuphezulu asikokuhamba kwesantya esiphezulu, kodwa kukuhamba kwesantya esizinzileyo. Iimetrikhi eziphambili kukuphindaphindwa kwesantya sokuhamba (ukuba imveliso nganye isondele kangakanani kowokugqibela) kunye nokushukuma (ukuguquguquka okuncinci kwisantya sokuhamba). Iinkqubo zokuchaneka okuphezulu zifuna ukuba ukuhamba kwesantya sokuhambaimpompo encinci ye-12 V DCihlala ihleli ixesha elide kunye nexesha lomjikelo.

2 Ukudibanisa intloko: Fumana indawo efanelekileyo yokulinganisela

Intloko (okanye intloko) ibhekisa kuxinzelelo oluveliswa yipompo. Olu xinzelelo kufuneka luhambelane ngokugqibeleleyo nokumelana (okanye intloko yenkqubo) okuveliswa yimibhobho, izihluzi, kunye neevalvu kwinkqubo. Ukukhetha iipompo ezinelifti enkulu kakhulu kudlalisa amandla kwaye kubangele ukuguguleka okungeyomfuneko, ngelixa ilifti encinci kakhulu ithetha ukuba ipompo ayinakoyisa ukumelana kwenkqubo. Injongo kukufumanaimpompo yamanzi encinci ye-12Vigophe layo lokusebenza lihambelana ngokugqibeleleyo negophe lokuxhathisa lenkqubo.

Uyilo lwepompo: Yenza ipompo ibe nobukrelekrele ngakumbi

Ukulungiswa kuqala ngepompo ngokwayo. Itekhnoloji yanamhlanje yepompo encinci ibonelela ngeendlela ezahlukeneyo zokuphucula ukuchaneka.

1. yamkela i-motor ye-DC (BLDC) engenabhrashi: isitshixo sokufezekisa ulawulo lwesantya se-elektroniki

I-motor yebrashi yendabuko ineengxaki zokungqubana kunye nokuguguleka, ngoko ke kunzima ukufikelela kulawulo oluchanekileyo lwesantya. Ngokwahlukileyo koko, iteknoloji yepompo ye-DC engenamabhrashi ivumela ulawulo oluchanekileyo lwesantya se-elektroniki (ngesiqhelo ngemiqondiso ye-PWM). Olu lawulo oluchanekileyo luguqulela ngqo kwisantya sokuhamba esizinzileyo kakhulu, okwenza ipompo ye-DC engenamabhrashi ibe sisiseko sayo nayiphi na inkqubo echanekileyo.

2. Lungiselela ulwakhiwo lwentloko yepompo: Susa "i-jitter" yokuhamba

Ukunciphisa ukuhamba okuqhelekileyo "kwe-jitter" (i-pulsation) okuxhaphakileyo kwiimpompo zokufuduka ezilungileyo, abavelisi basebenzise iindlela ezahlukeneyo. Oku kuquka ukusetyenziswa kweempompo ezineentloko ezininzi, ezifana neempompo ze-diaphragm ezineentloko ezimbini, okanye ukuhlanganiswa kwee-pulsating dampers kwindawo yokuphuma kwempompo.Iimpompo zokuzilungiselela ze-12V, ukunciphisa i-pulsation kubalulekile ukuqinisekisa ukuhanjiswa kolwelo oluhamba kakuhle noluchanekileyo, ingakumbi xa kujongwana nokugeleza okuncinci.

Izisombululo zokudibanisa inkqubo: yenza inkqubo ihambelane

Kwaneyona pump ilungileyo kufuneka isebenzisane ukuze kusetyenziswe inkqubo ekrelekrele, ngaba singafikelela ngokwenene ekuchanekeni okuphezulu?

1. Ukubalwa ngokuchanekileyo kokuxhathisa kwenkqubo: Kuphephe ukuqikelela

Ngaphambi kokukhetha ipompo encinci ye-12V DC, injineli kufuneka ibale ngokuchanekileyo ukuhla koxinzelelo lwazo zonke izinto (iipayipi, izihlanganisi, izihluzi). Olu balo luqinisekisa ukuba intloko yepompo ekhethiweyo iyahlangabezana ngokuchanekileyo neemfuno zesicelo, ngaloo ndlela ithintela inkunkuma yamandla kunye nokungaphumeleli kwepompo kwangethuba.

2. Sebenzisa ulawulo oluvaliweyo: umsebenzi "wokulungisa ngokuzenzekelayo"

Ukusebenzisa ukuchaneka okuguquguqukayo yeyona ndlela isebenzayo yokulawula i-closed loop. Oku kufuneka kube kwimveliso yokuhamba kokufakwa kwepompo okanye isenzi soxinzelelo. Iisenzi zibuyisela idatha yexesha langempela kwii-actuators zepompo ze-elektroniki, zivumela ipompo ukuba ilungise ngokuzenzekelayo isantya sayo (nge-motor ye-DC engenamabhulashi) ukugcina isantya sokuhamba esijolise kuso nokuba ukuxhathisa kwenkqubo kutshintsha.

Ingcebiso yesisombululo sobungcali

Ulawulo lolwelo oluchanekileyo kakhulu lufuna iqabane eliqondayo zombini iindlela zokumpompa kunye nolawulo lwe-elektroniki. IPincheng Motor igxile ekuboneleleni ngobuchule obuphezuluimpompo yamanzi encinciizisombululo. Imveliso yayo ephambili yimodyuli yokulawula i-DC engenamabhrashi evaliweyo eyenza imveliso yayo encinci yepompo ye-DC ye-12 volt ikwazi ukuphinda-phinda ukuhamba kwe-±1%. IPincheng Motor ibonelela ngeentloko zepompo ezenzelwe wena kunye nezisombululo zedrive ezidibeneyo ukunceda iinjineli zihambelane ngokugqibeleleyo nee-curve zokusebenza kwepompo neemfuno zenkqubo, nto leyo eyenza ukuba ibe liqabane elifanelekileyo lolawulo lolwelo oluchanekileyo.

isiphelo

Ukuphucula iimpompo ezincinci ukuze kulawulwe ngokuchanekileyo okuphezulu yinkqubo ecwangcisiweyo edibanisa uyilo lwempompo oluphambili kunye nokuhlanganiswa kwenkqubo ekrelekrele. Ngokugxila kulawulo lwesantya kunye nempendulo evaliweyo yeemoto zeDC ezingenamabhrashi (BLDCS), ungayiguqula ipompo yamanzi encinci ye-12V eqhelekileyo ibe yinxalenye yolawulo lolwelo oluthembekileyo noluchanekileyo.
