Ukulinganiswa kwamanqanaba kunokuba yiparameter ebalulekileyo yokusebenza kumashishini aqala kwioyile negesi ukuya kunyango lwamanzi. Phakathi kweendlela ezahlukeneyo zobuchwepheshe ezikhoyo, izixhobo zokudlulisa uxinzelelo kunye noxinzelelo olwahlukileyo (DP) zisetyenziswa kakhulu njengezixhobo zokujonga umgangatho wolwelo. Kwisiseko sayo, ukulinganiswa kwamanqanaba okuxinzelelwa kusekwe kumgaqo woxinzelelo lwe-hydrostatic, amandla asetyenziswa lulwelo oluphumlileyo ngenxa yomxhuzulane. Uxinzelelo kuyo nayiphi na indawo kwikholamu yolwelo luhambelana nokuphakama okungaphezulu kwelo nqaku, uxinano lwalo, kunye nokukhawuleziswa komxhuzulane. Ubudlelwane bubonakaliswa yifomyula:
P = ρ × g × h
Apho:
P = Uxinzelelo lwe-hydrostatic
ρ = Ubuninzi bolwelo
g = Ukukhawulezisa amandla adonsela phantsi
h = Ukuphakama kwekholamu yolwelo
I-sensor yoxinzelelo ebekwe ezantsi kwitanki inokulinganisa olu xinzelelo, emva koko ibale inqanaba lolwelo kwaye iyiguqule ibe yisignali yombane ngesekethe logama nje kusaziwa ukuba uxinano oluphakathi lungakanani.
Zombini iiTransmitters zoxinzelelo kunye nezoxinzelelo ezahlukeneyo zingasetyenziselwa ukulinganisa amanqanaba, kodwa usetyenziso lwazo luyahluka ngokusekelwe kwimeko yokusebenza:
Umthumeli woxinzelelo
Umlinganiselo:Uxinzelelo oluhambelana noxinzelelo lomoya.
Imeko yokusetyenziswa:Ilungele iitanki ezivulekileyo okanye imijelo apho umphezulu wolwelo utyhileke emoyeni. Umzekelo, kwindawo yokugcina amanzi, imveliso yomthumeli ihambelana ngokuthe ngqo nomgangatho wamanzi.
Ufakelo:Ifakwe ezantsi kwetanki okanye ifakwe emanzini angaphantsi.
Umthumeli woxinzelelo olwahlukileyo (DP)
Umlinganiselo:Umahluko phakathi koxinzelelo olubini: uxinzelelo lwe-hydrostatic ezantsi kwetanki kunye noxinzelelo olungaphezulu komphezulu wolwelo.
Imeko yokusetyenziswa:Kubalulekile kwiitanki ezivaliweyo/ezicinezelweyo apho uxinzelelo lwangaphakathi (oluvela kwiigesi, umphunga, okanye i-vacuum) luchaphazela umlinganiselo. Umlinganiselo we-DP unako ukuhlawula ukugqwetheka nokuqinisekisa idatha echanekileyo yenqanaba.
Ufakelo:Icala elinoxinzelelo oluphezulu liqhagamshela kwisiseko setanki ngelixa icala elinoxinzelelo oluphantsi liqhagamshela kwincopho yetanki.
Ukuseta isitshixo ekulinganisweni kwenqanaba elisekelwe kuxinzelelo
Indlela Yokufaka Izinto Ezixhonyiweyo:Iitransmitter kufuneka zifakwe kwinqanaba eliphantsi lolwelo olulindelekileyo ukuze kuthintelwe ukulinganiswa okomileyo. Ulwakhiwo kunye nemeko yenqanawa kufuneka ziqinisekise ukuba iisensa ezintywilayo zinokuntywiliselwa rhoqo ezantsi. Iityhubhu zomgca we-impulse zetransmitter ye-DP mazingabi nazithintelo, ukuvuza kunye namaqamza egesi.
Imeko yokusingqongileyo kunye nePhakathi:Uqhagamshelo lwe-capillary olukude lunokusetyenziswa ukwahlukanisa ii-sensors kubushushu ukuthintela umonakalo we-elektroniki ovela kubushushu obugqithisileyo bolwelo. Uqhagamshelo lwenkqubo ngee-diaphragm seals okanye izinto ezimelana nokugqwala lunokukhusela i-sensor kulwelo olunamandla. Umlinganiselo woxinzelelo lwe-transmitter kufuneka udlule uxinzelelo oluphezulu lokusebenza kuquka neemeko zokugaleleka.
Uphawu oluPhambili kunye noHlanganiso:Itekhnoloji yanamhlanje inokuqaliswa ukuphucula ukuthembeka kwezixhobo. Unxibelelwano olukrelekrele luvumela ukuhlanganiswa okugudileyo neenkqubo zolawulo kunye nokuxilongwa ngexesha langempela okulumkisa iimpazamo okanye ukuvaleka. Iitransmitter ezininzi ezilinganisa inqanaba kunye nobushushu ngaxeshanye zinokwenza kube lula ukufakela kwaye zinciphise iindleko.
Iitransmitter zoxinzelelo kunye nezohlukeneyo zizixhobo ezinokusetyenziswa ngeendlela ezahlukeneyo zokulinganisa amanqanaba, ezibonelela ngempumelelo yeendleko kunye nokuguquguquka kuzo zonke iishishini.Shanghai WangyuanNgumvelisi onamava osebenza kushishino lwezixhobo. Singavuya ukuva kuwe, ukuba ufuna izisombululo zokubeka esweni umgangatho.
