Iimpompo yamanzi ye-elektronikiIlungisa ukuhamba kwe-coolant ejikelezayo ngokweemeko zokusebenza kwesithuthi kwaye ifezekisa ulawulo lobushushu bemoto yemoto. Yinxalenye ebalulekileyo yenkqubo yokupholisa yesithuthi esitsha samandla. Uvavanyo lokusebenza yinxalenye ebalulekileyo yophando nophuhliso kunye nokuveliswa kwepompo yamanzi. Okwangoku, uvavanyo lwepompo yamanzi ye-elektroniki yemoto Uphando lwetekhnoloji kunye nophuhliso lwezixhobo aluzange luhambelane nophuhliso lweepompo zamanzi ze-elektroniki, kwaye uphando malunga neendlela zokuvavanya lugxile kakhulu kwiipompo zamanzi zemveli. Inkqubo yovavanyo lwepompo yamanzi encinci ye-NF inokulinganisa iiparameter zokusebenza ezifana nokuhamba kwepompo, ukuphakanyiswa, kunye nokusebenza kakuhle kweshaft kubushushu begumbi, kwaye ifezekise idatha yovavanyo. Ukuqokelelwa ngokukhawuleza kokuqina komoya wepompo yamanzi. Ibhentshi yovavanyo lokuqina komoya wepompo yamanzi eyilwe ngokulula isebenzisa uxinzelelo olwahlukileyo ukuze ibone ukuqina komoya wepompo yamanzi. Inkqubo yovavanyo oluqhelekileyo lwepompo yamanzi iyilwe ngokusebenzisa iisekethe ezifakwe ngaphakathi kunye nezahlukileyo.
Ngokwemigangatho yoshishino i-QC/T288.2-2001 kunye ne-JB/T8126.9-2017 kunye neemfuno zomgaqo-nkqubo ezinxulumene noko, uvavanyo lohlobo lwepompo yamanzi okupholisa lubandakanya uvavanyo lokusebenza, uvavanyo lwe-cavitation, njl. Ngokuvavanya izinga lokuhamba, i-voltage, kunye ne-Current, uxinzelelo lokungena kunye nelokuphuma, ukubalwa kwentloko, amandla, ukusebenza kakuhle, i-NPSH kunye nezinye iiparameter zokusebenza, gqibezela umzobo wejika lokusebenza kwepompo zamanzi ze-elektroniki.
Ngokungafaniyo nempompo yamanzi okupholisa yoomatshini, isantya seimpompo yamanzi ye-elektronikiilawulwa yinkqubo yayo edibeneyo, kwaye i-voltage kunye nesignali yokulawula enikiweyo ingenza i-DC brushless motor yangaphakathi isebenze ngesantya esifanelekileyo. Indlela yendabuko yokuvavanya i-torque yemoto kunye nesantya sokubala amandla okufaka epompo yamanzi ayifanelekanga kwi-elektroniki. Uvavanyo lwepompo yamanzi, ixhotyiswe ngombane ocwangcisiweyo ukuze ifunde umva i-voltage xa ipompo yamanzi isebenza, ibale amandla okufaka emoto ngokusebenzisa umbane kunye ne-voltage, ize iphindaphindwe nge-efficiency coefficient ukuze ibe ngamandla okufaka epompo yamanzi ye-elektroniki.
Iiparameter zobugcisa eziphambili zenkqubo yovavanyo: uluhlu lokulinganisa ukuhamba kwamanzi 0~500L/min, ukuchaneka komlinganiselo ±0.2%FS; uluhlu lokulinganisa uxinzelelo lokungena kunye nokukhupha -100~200kPa, ukuchaneka kovavanyo ±0.1%FS; uluhlu lokulinganisa lwangoku 0~30A, ukuchaneka komlinganiselo ±0.1 %FS; uluhlu lokubonelela ngombane olucwangcisiweyo 0~24V, ukuchaneka kokufunda kwakhona ±0.1%FS, uluhlu lwamandla 0~200W; uluhlu lokulinganisa ubushushu -20~100℃, ukuchaneka komlinganiselo ±0.2%FS, uluhlu lokulawula ubushushu 0~80℃, ukuchaneka kolawulo ±2°C.
Isicwangciso sovavanyo lokusebenza ngokubanzi
Ngokwemigangatho yovavanyo lweshishini elifanelekileyo, uvavanyo oluqhelekileyo lokusebenza kweempompo zamanzi lufuna ukuba ngaphakathi koluhlu lwe-40% ~ 120% yesantya esilinganisiweyo sempompo, kufuneka kubekwe iindawo zokusebenza zokuhamba ezingaphantsi kwe-8 ngokulinganayo ngokwezinga eliphezulu nelincinci lokuhamba elidlula kumbhobho wovavanyo. Ngokusebenzisa ulawulo lwe-PID, Lungisa ukuvulwa kwevalvu elinganayo yokuphuma ukuze kuzinziswe ukuhamba kwindawo yokuhamba. Isensor ijonga uxinzelelo lokungena kunye nokuphuma, ubushushu, izinga lokuhamba kombhobho wovavanyo lwempompo yamanzi ye-elektroniki ngexesha langempela, kunye ne-voltage yokusebenza kunye namaxabiso eeparameter zangoku zempompo yamanzi ye-elektroniki. Xa i-flowmeter ijonga ukuba ukuhamba kombhobho kuzinzile Emva kwexesha elithile, bhala phantsi amaxabiso eparameter empompo yamanzi ye-elektroniki. Ukwazi ububanzi bombhobho, umahluko wokuphakama phakathi kokungena kunye nokuphuma, iiparameter zoxinano lolwelo kunye nokukhawulezisa komxhuzulane, bala ii-flow-head, amandla okuhamba, kunye nee-flow-efficiency curve zempompo yamanzi ye-elektroniki kwisantya esilinganisiweyo ｡
