Amamitha okugelezaziyizinto zokulinganisa ezibalulekile embonini yamakhemikhali, yokwelashwa kwamanzi, kaphethiloli kanye neyokukhiqiza. Ukuze kuhlolwe ukusebenza kokulinganisa kwemitha yokugeleza, kwamukelwa kabanzi izici ezimbili zokunemba okuyisisekelo: ukunemba kokufunda kanye nokunemba kwesikali esigcwele. Ochwepheshe abaningi bobunjiniyela bavame ukudida lezi zinkomba ezimbili, okuholela ekukhethweni okungafanele kwemishini, ukwahlulela kwedatha okungalungile kanye nokulawulwa kwenqubo okungazinzile. Ukucacisa umehluko phakathi kokunemba kokufunda kanye nokunemba kwesikali esigcwele kubalulekile ekusetshenzisweni kwemitha yokugeleza efanele, ukuhlaziywa kwedatha kanye nokwenza ngcono inqubo yezimboni.
Ukunemba kwesikali esigcwele, okuvame ukuphawulwa ngokuthi i-%FS (iphesenti lesikali esigcwele), kuyindlela yendabuko yokulinganisa ukunemba kwamadivayisi okulinganisa. Ichaza iphutha eliphakeme kakhulu elivunyelwe ngokusekelwe ebangeni lokulinganisa eligcwele lethuluzi. Inani lesikali esigcwele libhekisela emkhawulweni ophezulu webanga elilinganiswayo lemitha yokugeleza. Uma ububanzi besikali esigcwele sebunqunyiwe, iphutha eliphelele elibalwe yi-%FS liyi-consistent ezinzile kuyo yonke inkathi yokulinganisa. Isibonelo, uma imitha yokugeleza inobubanzi bokulinganisa obungu-0 kuya ku-100 m³/h kanye nokunemba kwesikali okuphelele okungu-±1%, iphutha layo eliphelele eliphezulu liqiniswe ku-±1 m³/h kuzo zonke izindawo zokulinganisa.
Isici esisobala kakhulu sokunemba okugcwele kwesilinganiso yinani layo elingaguquki lamaphutha. Inzuzo yalo isekubalweni okulula kanye nokulinganiswa okulula kwefektri, yingakho eziningi zemishini ezivamileamamitha okugelezakanye namamitha okugeleza kokucindezela okuhlukile ayisisekelo asebenzisa le ndinganiso. Kodwa-ke, inephutha elibonakalayo ezimweni zokulinganisa ukugeleza okuphansi. Lapho izinga lokugeleza langempela liseduze nomkhawulo ophansi webanga, iphutha eliphelele elilungisiwe libala ingxenye enkulu yenani elilinganisiwe, okuholela ekwehleni okukhulu kokunemba okulinganiselwe. Lokhu kusho ukuthi amathuluzi anesiqinisekiso sokunemba kwesikali esigcwele kuphela awakwazi ukugcina ukunemba okuphezulu ngaphansi kwezimo zokusebenza eziphansi neziguquguqukayo.
Ngokuphambene nalokho, ukunemba kokufunda, okuvezwa njenge-%RD (iphesenti lokufunda), kuyindinganiso yokunemba ephezulu esetshenziswa kabanzi kumamitha okugeleza ahlakaniphile anamuhla njengemitha yokugeleza kagesi kanye namamitha okugeleza e-ultrasonic. Ngokungafani nephutha eliphelele elihleliwe, ukunemba kokufunda kubala iphutha elivumelekile ngokusekelwe enanini lokugeleza elilinganisiwe ngesikhathi sangempela. Iphutha eliphelele liyashintsha ngokuguquguqukayo ngokushintshashintsha kwesilinganiso sokugeleza kwangempela, okuqinisekisa ukunemba okuzinzile phakathi kwebanga lokulinganisa.
Uma sithatha ukunemba kokufunda okungu-±0.5%RD njengesibonelo, lapho izinga lokugeleza elilinganisiwe lingu-100 m³/h, iphutha eliphelele lingu-±0.5 m³/h; lapho izinga lokugeleza lehla liye ku-10 m³/h, iphutha eliphelele liyehla liye ku-±0.05 m³/h ngokufanele. Le ndlela yokulungisa amaphutha enamandla ivumela ithuluzi ukuthi ligcine ukunemba okuphezulu okuqhubekayo kungakhathaliseki ukuthi lilinganisa ukugeleza okuphezulu noma ukugeleza okuphansi. Lena inzuzo eyinhloko yokunemba kokufunda, okwenza lifanelekele izimo zezimboni eziyinkimbinkimbi ezinezinkulu.ukuguquguquka kokugelezakanye nezidingo zokulinganisa eziphezulu.
Umehluko obalulekile phakathi kwalezi zindinganiso ezimbili usesilinganisweni sokubala amaphutha kanye nokusebenza kwebanga eliphansi. Ukunemba kwesikali esigcwele kusebenzisa umkhawulo ophezulu ohleliwe webanga eliphelele njengesilinganiso, onephutha eliphelele elizinzile kodwa ukunemba okuphansi okuphansi. Ukunemba kokufunda kuthatha ukufundwa kwesikhathi sangempela njengesilinganiso, onephutha eliphelele elintantayo kanye nokunemba okulinganiselwe okuzinzile kulo lonke ibanga. Ekukhetheni ubunjiniyela obusebenzayo, ukunemba kwesikali esigcwele kufanelekile ezimweni zokusebenza ezinezinga elizinzileukugeleza kanye nokushintshashintsha okuncane, kuyilapho ukunemba kokufunda kuyindinganiso ekhethwayo yokugeleza okuguquguqukayo, ukulinganisa okunembe kakhulu kanye nezimo zokuxazululwa kwezentengiselwano.
Ekuphetheni, ukuqonda umehluko phakathi kokunemba kokufunda kanye nokunemba okugcwele kusiza onjiniyela ukuthi bahlulele ngokunembile ukusebenza kwangempela kwamamitha okugeleza. Ukukhetha indinganiso efanele yokunemba ngokwezimpawu zokukhiqiza kungagwema ngempumelelo amaphutha okulinganisa, kuthuthukise ukuthembeka kwedatha yezimboni, futhi kuqinisekise ukusebenza okuphephile, okuzinzile nokonga kwezinqubo zokukhiqiza zezimboni.
