Ukusukela oko kwaqala iProjekthi yoMbhobho werhasi eNtshona-Mpuma ngo-2001, irhasi yendalo iye yaba yeyona ndawo iphambili kuphuhliso lweshishini lamandla asekhaya, kwaye
Iimitha zokuhamba kobunzima begesi ye-thermalzibe zizixhobo ezifanelekileyo zokulinganisa umlinganiselo werhasi yoxinzelelo oluphezulu. Ngezantsi sihlalutya kwimbono yokusebenza kwemveliso kunye neendleko zofakelo, kutheni i-thermal gas mass flowmeter ingaba imitha ephantsi yomgangatho ofanelekileyo kumlinganiselo ophezulu woxinzelelo lwegesi yendalo.
1. Uhlalutyo lwentsebenzo yemveliso.
Kumlinganiselo ophezulu woxinzelelo lwegesi yendalo, ngenxa yomgama omde wombhobho, kulula ukuvelisa ilahleko yoxinzelelo kunye noxinzelelo oluphezulu lwegesi yendalo. I-flowmeter ye-thermal mass flowmeter inokuthembeka okulungileyo, ilahleko encinci yoxinzelelo, ubomi benkonzo ende, uluhlu olubanzi, kwaye inomsebenzi wokuzixilonga. Imitha egqwesileyo kwintsimi ye-high-pressure metering.
I-flowmeter ye-thermal mass flowmeter inomsebenzi we-plug-in we-intanethi, onokuhlola kwaye ulungise isixhobo phantsi kokuhamba okuqhelekileyo kwe-medium, edibana nomgaqo wokunikezelwa kwegesi yendalo engaphazanyiswa.
2. Uhlahlelo ngokwembono yorhwebo ngerhasi yendalo.
Imibhobho yomgama omde ngokubanzi ithatha uthutho loxinzelelo oluphezulu kwaye ifuna unikezelo lwerhasi olungaphazamisekiyo kumbhobho, ukwenzela ukuba ukutyhutyha ukuhamba kuveliswe lula kumbhobho. Ngethuba lenkqubo yokuhanjiswa kwegesi ukusuka phezulu ukuya ezantsi, i-valve iyothuka ngokulula xa i-valve ivuliwe, enokuthi ichaphazele ngokulula i-flowmeter ephantsi. Ukonakaliswa kwemitha yokuhamba kuya kubangela ukulinganiswa okungachanekanga kwemitha, kubangela iingxabano zorhwebo, kunye nokunyusa iindleko zokugcinwa kwemitha.
I-flowmeter ye-thermal mass flowmeter inokulinganisa ukuhamba kobuninzi begesi kwaye inokuchaneka komlinganiselo ophezulu kunye nokuzinza kokusebenza. Inokuqinisekisa ukuba iindawo zokurhweba ezinyukayo kunye nezisezantsi zenziwa ngokufanelekileyo, kwaye aziyi kuwela kwiingxabano zorhwebo ngenxa yokungaphumeleli kwesixhobo sokulinganisa.
3. Ukusuka kwimbono yezoqoqosho.
I
i-thermal gas mass flowmeterkunciphisa iindleko zokugcina ngenxa yokusebenza kwayo okuzinzile kwisicelo sentsimi, kwaye isixhobo sinobomi obude benkonzo. Xa kuthelekiswa nezinye iimitha, inemisebenzi yembuyekezo yobushushu kunye noxinzelelo. Akuyimfuneko ukuqwalasela abathumeli beqondo lokushisa kunye noxinzelelo loxinzelelo ngexesha lofakelo lwentsimi. Gcina iindleko zokuthenga, kunye neendleko zomjikelo wofakelo.
Enye imitha yokuhamba kwegesi khetha
