Xa udaya, ngaphambi kokuba ilaphu lingene etankini, qala uvule ivalvu yokungena kwamanzi ngenkqubo yolawulo ukuze ungene emanzini. Le ngeniso yamanzi ilawulwa ngokuzenzekelayo yinkqubo yolawulo lombane ngenqanaba lolwelo elimiselweyo. Xa ingeniso yamanzi ifikelela kwinqanaba lolwelo elimiselweyo, ivalvu yokungena kwamanzi ivalwa ngokuzenzekelayo ukuze kumiswe ingeniso yamanzi.
Olu buninzi bolwelo ngokwenene bubungakanani bolwelo olufunekayo ukuze ipompo ephambili kunye nombhobho zijikeleze kwaye zinyibilikise idayi, eyinxalenye yokuqala yesisombululo sedayi.
Ngenxa yokuba umatshini wokudaya usebenzisa ulawulo oluchanekileyo lwenqanaba lolwelo olusetyenziswa kwi-differential pressure transmitter analog quantity, ixabiso lenani le-analog liboniswa kwikhompyutha yokulawula endaweni yexabiso lenani lenani le-liquid. Kwinkqubo yokwenyani yokufaka, izixhobo zikwinkqubo yokuqala yokufakela nokulungisa iimpazamo, ngokubala kunye nokulungiswa kwenqanaba lamanzi, umthamo weliquid ohambelana nenqanaba ngalinye uyafunyanwa. Ke ngoko, ixabiso lenani leliquid lamanzi linokwaziwa ngenqanaba leliquid elilinganisiweyo eliboniswa yikhompyutha.
Kwitanki yohlobo olufanayo, ukungena kwamanzi kuyafana, oko kukuthi, inqanaba lolwelo elibekwe yinkqubo yolawulo lihlala lihleli. Enyanisweni, linqanaba lokhuseleko elihlangabezana nokusebenza okuqhelekileyo kwenkqubo yokujikeleza kotywala bedayi yomatshini wokudaya umoya. Nje ukuba imiselwe, imeko ngokubanzi ayidingi kutshintsha ngokuthanda kwayo.
Utshintshiselwano phakathi kwelaphu elidayiweyo kunye notywala bedayi lugqitywa kwinkqubo yempumlo. Ukuba kwitanki yokugcina ilaphu, inxalenye yelaphu eqokelelwe ngezantsi ifakwa kwimpumlo yedayi, kwaye inxalenye yelaphu eqokelelwe phezulu ayifakwanga kwimpumlo yedayi. Oku kuya kubangela ukungangqinelani kwamathuba okuba icandelo ngalinye lelaphu lidibane nesisombululo sedayi. Kwangaxeshanye, kuba le nxalenye yesisombululo sedayi itshintshiselana nesisombululo sedayi kwinkqubo yempumlo kunye nelaphu, kukho umahluko othile wobushushu kunye nomahluko woxinzelelo lwedayi, ngoko ke kulula ukubangela ukudaya Iingxaki zomgangatho wokudaya ezifana namacandelo angalunganga okudaya.
Ukuphakama kwamanzi kakhulu kuyawunyusa umlinganiselo wokuhlamba ngokudaya kunye neendleko zokuvelisa ukudaya. Ngenxa yokuba umlinganiselo wokuhlamba unokuhlangabezana neemeko zokudaya, akufuneki kwaphela ukwandisa umlinganiselo wokuhlamba ngokwenziwa.
Kwinkqubo yokuvelisa idayi yomatshini wokudaya, ukudaya ngokusisiseko kuhamba ngamanqanaba amane ukusuka ekunikeni ilaphu ukuya ekukhupheni ilaphu. Enye yezona zinto zibalulekileyo yinkqubo yokudaya, ebizwa ngokuba yinkqubo yokudaya.
Impembelelo yenkqubo yokudaya kumgangatho wokudaya
●Iidayi kunye neendlela zokongeza
●Ubushushu bokudaya
●Iintlobo zetyuwa kunye ne-alkali
● Ixesha lokudaya
●Umlinganiselo wokuhlamba ngotywala obudayiweyo
Phakathi kwezinto ezibangela impembelelo ezingentla, ukongeza kwindlela yokongeza iidayi, iityuwa, kunye ne-alkalis, kunye nomlinganiselo wokuhlamba, ezinye izinto zichaphazela kuphela umthunzi welaphu, oko kukuthi, izinto ezichaphazela izinga lokuqina kweedayi ezisabelayo.
Kwidayi ezisasazekileyo. Kwidayi yedayi esasazekileyo kwi-90℃, izinga lokufudumeza linokuba phezulu, kwaye ngaphezulu kwe-90℃, ingakumbi kufutshane ne-130℃, izinga lokufudumeza kufuneka lilawulwe ukuze lisondele kancinci kubushushu bokudaya ukuze kuthintelwe ukudaya okungalinganiyo. Ukudaya kweedayi ezisasazekileyo kuchaphazeleka kakhulu bubushushu. Ke ngoko, kummandla wobushushu apho idayi ifunxwa khona, ukwandisa inani lemijikelo yelaphu kunye notywala bedayi kunokwenza idayi kunye nokusasazwa kobushushu kwigumbi lokudaya kufane, nto leyo eluncedo ekudayini okulinganayo kwelaphu.
Emva kokuba kugqityiwe ukudaya, ubushushu kufuneka buncitshiswe kancinci ekuqaleni ukuze kuthintelwe imibimbi yelaphu ebangelwa kukupholisa ngequbuliso. Xa ubushushu buhla bufikelela kwi-100°C, ubushushu bunokupholisa ngokukhawuleza bufikelele kwi-80°C, emva koko kucocwa ukugqithisela ukuze kuncitshiswe ubushushu kwigumbi lokudaya. Ukuba ukukhupha kunye nokungena kwamanzi kwenziwa kubushushu obuphezulu, kulula ukwenza imibimbi yelaphu kwaye kuchaphazele umgangatho wokudaya.
