Iimpazamo ezininzi ziyaphinda zenzeke kokubini ekusetweni nasekusetyenzisweni kwezixhobo zokulinganisa ubungqingili bepeyinti emgceni:
- Indawo yesensor engalunganga: Ukufaka iiprobe kwiindawo ezinemibhobho embi, iindawo ezimileyo, okanye amaqamza omoya kukhokelela ekufundweni okungachanekanga. Imodeli yokubala, efana neCFD, inceda ekuchongeni ubunzulu bokuntywiliselwa, i-engile, kunye nesantya esifanelekileyo, ukuqinisekisa ukuba i-sensor ivezwa kumjelo wesampulu omeleyo.
- Ukungahoyi imbuyekezo yobushushu: Ukubonakala kwepeyinti kuxhomekeke kakhulu kubushushu. Ukusilela kokudibanisa ukulungiswa kobushushu kuvelisa iindlela ezilahlekisayo. Iinkqubo zanamhlanje ezingaphakathi zilungisa ngokuzenzekelayo ukuguquguquka kobushushu.
- Ukungayinaki indlela yokulinganisa: Ekuhambeni kwexesha, ukufakwa, ukungcola, okanye ukuguguleka koomatshini kuchaphazela imveliso yesensor. Ukulinganiswa okucwangcisiweyo kusetyenziswa imigangatho ye-viscosity yepeyinti okanye ulwelo olubhekiselele kuyo kubalulekile.
- Ukucoca nokugcinwa kakubi: Ukuqokelelwa kweentsalela zepeyinti kutshintsha uvakalelo lwe-probe kwaye kubangele iziphumo ezingalunganga, ingakumbi kwiinkqubo ezinombala kakhulu. Emva kokucoca okucwangcisiweyo kunye neenkqubo zokulungisa emva kweqela zijongana nale meko.
- Ukukhetha izixhobo ngendlela engafanelekangaUkukhetha i-viscometer engafanelekanga kwi-rheology yepeyinti—umz., ukusebenzisa isixhobo esijikelezayo esisisiseko kwipeyinti ye-thixotropic—kunokubangela impazamo eqhubekayo.
- Impendulo ebambezelekileyo kwiindlela ezingaqhelekanga: Ukungaphumeleli ukusebenzisa izilumkiso zexesha langempela kunye neempendulo ezizenzekelayo kuvumela imveliso engakhange ichazwe ukuba ingabonwa. Izixhobo zokulinganisa i-viscosity ezingaphakathi eziqhagamshela kulawulo lwenkqubo zinokunciphisa ukujongwa ngesandla.
Ukuze uphephe le migibe:
- Soloko uqinisekisa ukufakwa kwesixhobo ngesikhokelo somenzi okanye uhlalutyo lwe-CFD.
- Sebenzisa iinkqubo ezihlawulelwa ubushushu kwaye uqinisekise ukulinganiswa rhoqo.
- Coca iiprobe ngendlela ecwangcisiweyo.
- Hlanganisa ukukhethwa kwezixhobo neendlela ezithile zokulinganisa ubungqindilili bepeyinti ezifanelekileyo kwizixhobo.
- Hlanganisa ii-alamu zexesha langempela kunye neendlela zokulungisa iinkqubo ngokuzenzekelayo.
Iingcebiso zokugcinwa kunye nokulinganiswa kwee-inline viscosity probes
Ukugcinwa kunye nokulinganiswa okufanelekileyo kuqinisekisa ukuchaneka kweendlela zokumisela i-viscosity yepeyinti, ukwandisa ubomi be-probe, kunye nokuxhasa ukusebenza kakuhle kwenkqubo:
- Ukucoca Okuqhelekileyo: Susa ukwakheka kwepeyinti emva kwebhetshi nganye yemveliso, ingakumbi kwiipeyinti ezizaliswe kakhulu okanye ezikhawuleza ukubola. Sebenzisa izinyibilikisi nezixhobo ezicetyiswa ngumvelisi ukuthintela umonakalo we-sensor.
- Uhlengahlengiso olucwangcisiweyo: Lungisa iiprobe ngamaxesha athile achazwe yimigangatho yomgangatho, okanye emva kokulungiswa kwayo nayiphi na indlela. Sebenzisa ulwelo olubhekiselele kuzo okanye iipeyinti ezisemgangathweni ezilinganisa ngokusondeleyo iimeko zenkqubo.
- Ukuqinisekiswa kweSensor: Qinisekisa imilinganiselo emgceni usebenzisa izixhobo zokuvavanya i-viscosity yepeyinti yelabhoratri engaxhunyiwe kwi-intanethi usebenzisa imigangatho yoshishino.
- Amaxwebhu: Gcina iirekhodi zemisebenzi yolondolozo, ukulinganisa, kunye nokuqinisekisa ukuqinisekisa ukulandelelwa kunye nokuthobela imithetho.
- Ufakelo kunye nokubekwa okufanelekileyo: Sebenzisa izikhokelo—kwaye, apho zifumaneka khona, ulwazi oluvela kwizifundo ze-CFD—ukukhetha ubunzulu benzwa, ulungelelwaniso, kunye nesantya sokuhamba.
- Ukuhlolwa nokuQondwa koMbono: Hlola rhoqo iisensa zokubona umonakalo okanye iintsalela, kwaye usebenzise imisebenzi yokuxilonga ekwikhompyutha ukuze ufumanise ukungasebenzi kakuhle kwangethuba.
Iindlela zokulungisa azigcini nje ngokugcina iimitha ze-viscosity zepeyinti zisebenza ngokuchanekileyo kodwa zikwanegalelo ekulinganisweni kokuhamba kwepeyinti ukuze kulawulwe umgangatho kunye nokunciphisa inkunkuma yenkqubo. Ukuqwalaselwa rhoqo kwezi nkcukacha kunciphisa ixesha lokungasebenzi kwaye kuhambelana nozinzo oluqhubekayo kunye nemigangatho yokusingqongileyo kwimveliso yepeyinti yanamhlanje.
