Ukukhetha uphawu, nansi incazelo enemininingwane yesici ngasinye:
Ingcindezi: Izivalo kufanele zikwazi ukumelana nengcindezi ohlelweni ukuvimbela ukuvuza.Ukucindezela kungenye yezinto ezibalulekile ekukhetheni izimpawu ezifanele, futhi impahla yokuvala efanele kanye nesakhiwo sokuvala ngokuvamile kudingeka kunqunywe ngokusekelwe kubukhulu bengcindezi yokusebenza ekusetshenzisweni.
Izinga lokushisa: Uphawu kufanele lukwazi ukugcina ukunwebeka okuhle nokusebenza kokuvala ngaphakathi kwebanga lokushisa lokusebenza.Izakhiwo zezinto zokubeka uphawu zingashintsha ngaphansi kwezimo zokushisa eziphakeme noma eziphansi.Ngakho-ke, kuyadingeka ukukhetha izinto zokuvala ezingase zivumelane nezinga lokushisa elisebenzayo ukuze kuqinisekiswe umphumela wokuvala.
Izinhlobo zikawoyela weHydraulic: Izinhlobo ezahlukene zamafutha we-hydraulic zinezakhi zamakhemikhali ezihlukile kanye nezakhiwo.Amanye amafutha e-hydraulic angase abe nomthelela obolayo noma wokuncibilika ezintweni zokuvala, ngakho-ke kubalulekile ukukhetha izinto zokuvala ezihambisana namafutha we-hydraulic asetshenzisiwe.
Indlela esebenza ngayo: Ukuthi uphawu lusebenza kanjani nakho kufanele kucatshangelwe.Isibonelo, ama-seal angase adinge ukumelana nokudlidliza kwemvamisa ephezulu, ukushaqeka okukhulu, noma ukunyakaza kwesivinini esikhulu.Kulokhu, kuyadingeka ukukhetha into yokubeka uphawu ngokumelana okuhle kokugqoka, ukuqina nokukhubazeka.
Sekukonke, kunezici eziningana okufanele zicatshangelwe lapho ukhetha uphawu olulungile, okuhlanganisa ukucindezela, izinga lokushisa, uhlobo lwe-hydraulic fluid kanye nendlela yokusebenza.Ngokucubungulisisa lezi zici, kungakhethwa izinto ezifanele zokuvala kanye nezakhiwo ukuze kunikeze imiphumela enokwethenjelwa yokuvala kanye nokusebenza kokusebenza.
Ngaphezu kwalokho, kunezinye izici okufanele zicatshangelwe:
Ukumelana Namakhemikhali: Izimpawu kufanele zimelane namakhemikhali ahlangana nazo, njengama-acids, ama-alkali, izincibilikisi, njll. Ezindaweni ezisetshenziswayo ezikhethekile, njengasembonini yamakhemikhali noma ukucubungula ukudla, izinto zokuvala ezinokumelana kahle namakhemikhali kudingeka kukhethiwe.
Ukusebenza Kokutywina: Ukusebenza kokuvalwa kwezimpawu kubalulekile ukucatshangelwa.Ukusebenza kahle kokuvalwa kungavimbela ngempumelelo ukuvuza kanye nokungena kokungcola, ngaleyo ndlela kuqinisekise ukusebenza okuvamile kwesistimu.
Ubude bokuphila: Izivalo zidinga ukuphila okwanele ukuze kuncishiswe imvamisa yokushintshwa nokugcinwa.Izinto zokufaka uphawu kufanele zibe nokumelana okuhle kokugqoka kanye nokumelana nokuguga ukuze kunikeze umphumela wokufaka uphawu onokwethenjelwa wesikhathi eside.
Izindleko: Izindleko zophawu nazo ziyisici okufanele sicatshangelwe.Izinto zokufaka uphawu ezihlukene kanye nokwakhiwa kungase kube nezindleko ezihlukene, futhi uphawu olufanele ludinga ukukhethwa ngokusekelwe ezidingweni zohlelo lokusebenza kanye nesabelomali.
Ukufingqa, ekukhethweni kwezimpawu, izici eziningi ezifana nokucindezela, izinga lokushisa, uhlobo lukawoyela we-hydraulic, indlela yokusebenza, ukumelana namakhemikhali, ukusebenza kahle kokuvala, impilo kanye nezindleko zidinga ukucatshangelwa.Ngokucabangela lezi zici, izinto ezifanele zokuvala kanye nezakhiwo zingakhethwa ukuhlangabezana nezidingo zohlelo lokusebenza futhi zinikeze umphumela wokuvala othembekile.
