Umlinganiselo ochanekileyo wesantya sokuhamba ubalulekile kugcino lwamandla olusebenzayo kunye nokulungiswa kwamashishini kunye nezityalo zemichiza. Khetha indlela efanelekileyo iyona nto ibalulekileyo ngokohlobo lolwelo, iimfuno zenkqubo, kunye neenkcukacha zesicelo. Iimpawu ze-fluid ziyahluka kwi-viscosity, ubuninzi, ubushushu, ixabiso le-pH kunye namandla anokugqwala. Ngaphezu koko, iimeko zenkqubo ezifana noxinzelelo, ulawulo lokuhamba kunye nokusingqongileyo okusetyenziswayo kufuneka kunikwe ingxelo.
Yintoni inqanaba lokuqukuqela?
Umyinge wokuqukuqela ubhekisa kubungakanani bolwelo oluthumela ngenqaku ngexesha leyunithi. Ilinganiswa ngeeyunithi ezifana neelitha ngesekhondi okanye iigaloni ngomzuzu ngokwesiqhelo. Yiparameter ebalulekileyo kubunjineli behydraulic kunye nesayensi yezonyango. Iinjineli ziyakwazi ukufumana ulwazi kulawulo lolwelo, ngakumbi ukufaka isandla ekuphuculeni ukusetyenzwa kwemizi-mveliso kunye nokwenza izigqibo ezinolwazi.
Izinto eziPhembelela ireyithi yokuHamba
Ukuqonda izinto ezichaphazela umyinge wokuhamba yimfuneko yokukhetha eyona meko ilungileyo yomlinganiselo wesantya sokuhamba. Uhlobo lwe-fluid, ipropati, ulawulo lokuhamba, ubushushu, uxinzelelo, ubungakanani bombhobho, ukulungelelaniswa kunye neemeko zokufakela zonke izinto ezichaphazela izinga lokuhamba.
Chonga uhlobo lolwelo
Kubalulekile ukuchonga ukuba yeyiphi imidiya osebenza nayo. Itekhnoloji ethile yokulinganisa ukuhamba kufuneka yamkelwe ngokwahlukileyo kulwelo ngalunye. Umzekelo, iirhasi zinokucinezelwa kodwa ulwelo alwenzi; Ubuninzi bomphunga buyaguquguquka. Ulwelo lwe-viscosity ephezulu njenge-oyile isasazeka ngemibhobho ngokwahlukileyo kunolwelo olusezantsi lwe-viscosity njengamanzi. Kuyimfuneko ukuba abanini kunye neenjineli zezityalo ezahlukeneyo bakhethe ubugcisa obufanelekileyo bomlinganiselo ochanekileyo kunye nolawulo oluchanekileyo.
Lilinganisa njani ireyithi yokuHamba?
Volumetric okanye Mass Flow Meters
Ukwenza ukhetho phakathi kwe-volumetric okanye i-mass flow measurement linyathelo elibalulekileyo ngaphambi kokuphucula ukuchaneka kweenkqubo zolwelo.Iimitha zokuhamba ngeVolumetriczilungele ulwelo loxinaniso oluhlala kwinqanaba elizinzileyo, ingakumbi ulwelo kunye neegesi ezikwinkqubo yokucubungula.Umlinganiselo wokuhamba kobuninziiyimfuneko xa uxinaniso lutshintsha ngobushushu kunye noxinzelelo. Ngokujonga nje esi sizathu, iimitha zokuqukuqela kobunzima ziyasetyenziswa ukubamba isixa sisonke semathiriyeli edlula kwindawo nganye ngexesha leyunithi.

Ukulinganisa inani leReynolds (ukuba kuyimfuneko)
Ukulinganisa inani le-Reynolds ukuqikelela indlela yokuhamba ngokusekwe kwisantya solwelo, ukuxinana, i-viscosity kunye nedayamitha yombhobho, nokuba yi-laminar okanye isiphithiphithi. Ulwelo lunokuthathwa njenge-laminar xa inani le-Reynolds lingaphantsi kwama-2,000 malunga. Ngamanye amazwi, ulwelo lunesiphithiphithi xa inani leReynolds lingaphezulu kwama-4,000. Jonga inkqubo yokuqukuqela ngamanani eReynolds ngokubaluleka kokusebenza kunye nokuchaneka kweemitha zokuhamba.
UFakelo lwemitha yokuHamba
Ukufakela imitha yokuhamba kwinqanaba elichanekileyo kwi-bends engenanto, i-valve kunye nokunye ukuphazamiseka kuyisisombululo esona sisisombululo esihle kakhulu sokusebenza kakuhle, apho ukuhamba kwamanzi kuhlala kuhleli kwaye kufana. Ukongeza kwizinto ezingentla apha, ukulungelelaniswa sesinye isizathu esichaphazela ukuchaneka kweemitha zokuphazamiseka kokuhamba okubangelwa naluphi na uhlobo lokungahambi kakuhle. Iimpazamo zokusebenza kunye nokusebenza kungaphuculwa kangangoko ukuba zonke ezo nkcukacha zibalwe xa kufakelwa.
Yenza ulungelelwaniso oluyimfuneko phambi komlinganiselo ongaguqukiyo
Ulungelelwaniso lubalulekile ukuze kuqinisekiswe ukuchaneka kwemitha yombane wakho, ngakumbi kwizicelo zamashishini apho ukuchaneka kubaluleke kakhulu. Ukuqhuba ulungelelwaniso kubandakanya ukuthelekisa imveliso yemitha kunye nomgangatho owaziwayo kunye nohlengahlengiso njengoko kufunekayo ukuqinisekisa ukuba ufundo luphakathi kwemigangatho yonyamezelo eyamkelekileyo. Ukulinganisa rhoqo akugcini nje ukugcina ukuchaneka kwemitha kodwa kwandisa ubomi bayo bokusebenza, ukuthintela iimpazamo ezibiza kakhulu okanye ukungasebenzi kakuhle kulawulo lwenkqubo.
