Iimitha zokuhambazizixhobo zokulinganisa ezibalulekileyo kwiinkampani zamakhemikhali, unyango lwamanzi, ipetroli kunye nemveliso. Ukuvavanya ukusebenza komlinganiselo wemitha yokuhamba, kwamkelwa ngokubanzi iinkcukacha ezimbini zokuchaneka okuphambili: ukuchaneka kokufunda kunye nokuchaneka kwesikali esipheleleyo. Iingcali ezininzi zobunjineli zihlala zibhidanisa ezi mpawu zimbini, nto leyo ekhokelela ekukhethweni okungafanelekanga kwezixhobo, ukugweba idatha ngokungachanekanga kunye nolawulo lwenkqubo olungazinzanga. Ukucacisa umahluko phakathi kokuchaneka kokufunda kunye nokuchaneka kwesikali esipheleleyo kubalulekile ekusetyenzisweni kwemitha yokuhamba ngokuchanekileyo, uhlalutyo lwedatha kunye nokwenza ngcono inkqubo yemizi-mveliso.
Ukuchaneka kwesikali esipheleleyo, okuhlala kuphawulwa njenge-%FS (ipesenti yesikali esipheleleyo), yindlela yendabuko yokulinganisa ukuchaneka kwezixhobo zokulinganisa. Ichaza impazamo ephezulu evumelekileyo ngokusekelwe kuluhlu lokulinganisa olupheleleyo lwesixhobo. Ixabiso elipheleleyo lesikali libhekisa kumda ophezulu woluhlu olulinganiswayo lwemitha yokuhamba. Nje ukuba uluhlu olupheleleyo lwesikali lumiselwe, impazamo epheleleyo ebalwe yi-%FS yi-consistent esisigxina kulo lonke ixesha lokulinganisa. Umzekelo, ukuba imitha yokuhamba inoluhlu lokulinganisa oluphakathi kwe-0 ukuya kwi-100 m³/h kunye nokuchaneka kwesikali esipheleleyo se-±1%, impazamo yayo ephezulu epheleleyo iqiniswe kwi-±1 m³/h kuzo zonke iindawo zokulinganisa.
Eyona nto icacileyo yokuchaneka kwesikali esipheleleyo lixabiso layo elizinzileyo leempazamo. Inzuzo yayo ikukubala okulula kunye nokulungiswa okulula kwefektri, yiyo loo nto uninzi lwezixhobo zemveli zoomatshiniiimitha zokuhambakwaye iimitha zokuhamba koxinzelelo oluhlukileyo ezisisiseko ziyawamkela lo mgangatho. Nangona kunjalo, ineengxaki ezibonakalayo kwiimeko zokulinganisa ukuhamba okuphantsi. Xa izinga lokuhamba lokwenyani lisondele kumda ophantsi woluhlu, impazamo epheleleyo esisigxina ibandakanya inxalenye enkulu yexabiso elilinganisiweyo, nto leyo ekhokelela ekwehleni okukhulu kokuchaneka okulinganiselweyo. Oku kuthetha ukuba izixhobo ezinesiqinisekiso sokuchaneka kwesikali esipheleleyo azinakugcina ukuchaneka okuphezulu phantsi kweemeko zokusebenza eziphantsi kunye neemeko zokusebenza eziguquguqukayo.
Ngokwahlukileyo koko, ukuchaneka kokufunda, okuchazwa njenge-%RD (ipesenti yoKufunda), ngumgangatho wokuchaneka okuphezulu osetyenziswa kakhulu kwiimitha zokuhamba ezikrelekrele zanamhlanje ezifana neemitha zokuhamba ze-electromagnetic kunye neemitha zokuhamba ze-ultrasonic. Ngokungafaniyo nempazamo epheleleyo esisigxina, ukuchaneka kokufunda kubala impazamo evumelekileyo ngokusekelwe kwixabiso lokuhamba elilinganisiweyo ngexesha langempela. Impazamo epheleleyo itshintsha ngokuguquguqukayo ngokuguquguquka kwesantya sokuhamba sokwenyani, ukuqinisekisa ukuchaneka okuzinzileyo okuthelekisekayo kuluhlu oluninzi lokulinganisa.
Ukuthatha ukuchaneka kokufunda kwe-±0.5%RD njengomzekelo, xa izinga lokuhamba elilinganisiweyo liyi-100 m³/h, impazamo epheleleyo yi-±0.5 m³/h; xa izinga lokuhamba liyehla liye kwi-10 m³/h, impazamo epheleleyo iyehla iye kwi-±0.05 m³/h ngokufanelekileyo. Le ndlela yokuhlawula iimpazamo ezinamandla ivumela isixhobo ukuba sigcine ukuchaneka okuphezulu okulinganayo nokuba kulinganisa ukuhamba okuphezulu okanye ukuhamba okuphantsi. Le yeyona nzuzo iphambili yokuchaneka kokufunda, okwenza ukuba ifaneleke kwiimeko ezinzima zemizi-mveliso ezinkulu.ukutshintshatshintsha kokuhamba kwamanzikunye neemfuno zokulinganisa eziphezulu.
Umahluko obalulekileyo phakathi kwemigangatho emibini usekwe kwireyithingi yokubala iimpazamo kunye nokusebenza okuphantsi. Ukuchaneka kwesikali esipheleleyo kusebenzisa umda ophezulu omiselweyo njengomlinganiselo opheleleyo, kunye nempazamo epheleleyo ezinzileyo kodwa ukuchaneka okuphantsi okuphantsi. Ukuchaneka kokufunda kuthatha ukufundwa kwexesha langempela njengomlinganiselo, kunye nempazamo epheleleyo edadayo kunye nokuchaneka okuzinzileyo okunxulumeneyo kulo lonke uluhlu. Ekukhetheni ubunjineli obusebenzayo, ukuchaneka kwesikali esipheleleyo kufanelekile kwiimeko zokusebenza ezinezitezi ezizinzileyoukuhamba kwamanzi kunye nokuguquguquka okuncinci, ngelixa ukuchaneka kokufunda kungumgangatho okhethwayo wokuhamba okuguquguqukayo, ukulinganisa okuchanekileyo okuphezulu kunye neemeko zokuhlaliswa korhwebo.
Ukuqukumbela, ukuqonda umahluko phakathi kokuchaneka kokufunda kunye nokuchaneka kwesikali esipheleleyo kunceda iinjineli ukuba zigwebe ngokuchanekileyo ukusebenza kweyona mitha yokuhamba. Ukukhetha umgangatho ochanekileyo wokuchaneka ngokweempawu zemveliso kunokuthintela ngempumelelo iimpazamo zokulinganisa, kuphucule ukuthembeka kwedatha yemizi-mveliso, kwaye kuqinisekise ukusebenza okukhuselekileyo, okuzinzileyo nokungabizi kakhulu kweenkqubo zemveliso yemizi-mveliso.
