Uxinzelelo bubungakanani bamandla asetyenziswa ngokuthe nkqo kumphezulu wento, ngokwendawo nganye. Oko kukuthi,P = F/A, apho kucacile ukuba indawo encinci yoxinzelelo okanye amandla anamandla aqinisa uxinzelelo olusetyenziswayo. Ulwelo/Ulwelo kunye negesi nazo zinokusebenzisa uxinzelelo kunye nomphezulu oqinileyo.
Uxinzelelo lwe-hydrostatic lukhutshwa lulwelo kwi-equilibrium kwinqanaba elithile ngenxa yamandla omxhuzulane. Ubungakanani boxinzelelo lwe-hydraulic abunamsebenzi kubungakanani bendawo yomphezulu woqhagamshelwano kodwa kubunzulu bolwelo olunokubonakaliswa yi-equation.P = ρghYindlela eqhelekileyo yokusebenzisa umgaqo othiuxinzelelo lwe-hydrostaticukulinganisa inqanaba lolwelo. Logama nje ubuninzi bolwelo kwisikhongozeli esivaliweyo busaziwa, i-sensor engaphantsi kwamanzi inokunika ukuphakama kwekholamu yolwelo ngokusekelwe kufundo loxinzelelo olubonwayo.
Ubunzima bomoya emoyeni wehlabathi lethu bukhulu kakhulu kwaye buhlala bucinezela umphezulu womhlaba. Kungenxa yokuba kukho uxinzelelo lomoya apho uxinzelelo lohlulwahlulwa ngokweentlobo ezahlukeneyo ngexesha lokulinganisa.
Iiyunithi zoxinzelelo zahlukile ngokusekelwe kwimithombo eyahlukeneyo yoxinzelelo kunye neeyunithi zobungakanani obufanelekileyo bomzimba:
UPascal - Iyunithi yoxinzelelo lwe-SI, emele i-newton/㎡, apho i-newton yiyunithi yamandla ye-SI. Ubungakanani be-Pa enye buncinci kakhulu, ngoko ke, kwi-kPa kunye ne-MPa zisetyenziswa kakhulu.
I-Atm - Ubungakanani boxinzelelo oluqhelekileyo lomoya, lulingana ne-101.325kPa. Uxinzelelo lomoya lwangempela lwasekuhlaleni luyatshintshatshintsha malunga ne-1atm kuxhomekeke kukuphakama kunye neemeko zemozulu.
Ibha - Iyunithi yoxinzelelo lweMetriki. Ibha eyi-1 ilingana ne-0.1MPa, engaphantsi kancinci kune-atm. I-1mabr = 0.1kPa. Kulula ukuguqula iyunithi phakathi kwePascal kunye nebha.
I-Psi - Iiponti nge-intshi yesikwere, iyunithi yoxinzelelo lwe-avoirdupois esetyenziswa kakhulu yi-USA. I-1psi = 6.895kPa.
Ii-intshi zamanzi - Ichazwa njengoxinzelelo olusebenza ezantsi kwekholamu yamanzi ephezulu eyi-intshi eyi-1. 1inH2O = 249Pa.
Iimitha zamanzi - mH2U-O yinxalenye eqhelekileyo yeuhlobo lokuntywiliselwa komoya oludlulisela inqanaba lamanzi.
Iiyunithi zoxinzelelo ezahluliweyo ezahlukeneyo (kPa/MPa/bar)
Iintlobo zoxinzelelo
☆Uxinzelelo lwegeyiji: Uhlobo oluqhelekileyo lokulinganisa uxinzelelo lwenkqubo olusekelwe kuxinzelelo lokwenyani lomoya. Ukuba akukho xinzelelo longeziweyo ngaphandle kwexabiso lomoya elijikelezileyo, uxinzelelo lwegeyiji luyi-zero. Luba luxinzelelo olubi xa uphawu lokufundwa luyi-minus, ixabiso lalo elipheleleyo lingadluli uxinzelelo lomoya lwendawo olujikeleze i-101kPa.
☆Uxinzelelo oluvaliweyo: Uxinzelelo oluvaleleke ngaphakathi kwi-diaphragm yesensa esebenzisa uxinzelelo oluqhelekileyo lomoya njengesiseko sereferensi. Isenokuba yinto elungileyo okanye embi, eyaziwa ngokuba yi-overpressure kunye ne-partial vacuum ngokwahlukeneyo.
☆Uxinzelelo olupheleleyo: Uxinzelelo olusekelwe kwi-vacuum epheleleyo xa yonke into ingenanto kwaphela, esenokungafikelelwa ngokupheleleyo phantsi kweemeko eziqhelekileyo eMhlabeni kodwa inokuba kufutshane kakhulu. Uxinzelelo olupheleleyo lungaba yi-zero (i-vacuum) okanye lulungile kwaye alunakuba lubi.
☆Umahluko woxinzelelo: Umahluko phakathi koxinzelelo lweezibuko zokulinganisa. Umahluko uninzi lwawo luhle kuba iizibuko zoxinzelelo eziphezulu neziphantsi zihlala zimiselwe kwangaphambili ngokwendlela eyilwe ngayo inkqubo yenkqubo. Uxinzelelo olwahlukileyo lungasetyenziselwa ukulinganisa amanqanaba ezikhongozeli ezivaliweyo kwaye njengoncedo kwiintlobo ezithile zeemitha zokuhamba.
IShanghaiWangYuan, ingcali yokulawula iinkqubo engaphezu kweminyaka engama-20 yenza izixhobo zokulinganisa uxinzelelo ezamkela zonke iintlobo zeemfuno ezenziwe ngokwezifiso kwiiyunithi zoxinzelelo kunye neentlobo. Zonke iimveliso zilinganiswa ngokupheleleyo kwaye zihlolwe ngaphambi kokuba ziphume kumzi-mveliso. Iimodeli ezine-integral indicator zinokulungisa iyunithi ebonisiweyo ngesandla. Nceda uzive ukhululekile ukuqhagamshelana nathi ngeemfuno zakho kunye nemibuzo.
