I-engile yokutshiza yemilomo okanye ulawulo lokuhamba ngexesha leyunithi kufuneka imiselwe kwasekuqaleni. Ngokubanzi, siza kwenza umlomo ngemilomo esemgangathweni xa sisenza imveliso. I-engile yokutshiza yemilomo kunye nereyithi yokuhamba kwexesha ngokweyunithi imiselwe, ke i-engile yokutshiza yemilomo Kwaye inqanaba lokuhamba kufuneka limiselwe ngaphambi kokuba kwenziwe umlomo (ngaphandle kwemilomo ekhethekileyo ehlengahlengiswayo).

Ke emva kokuba uthengile umlomo, kunzima ngakumbi ukulawula iiparameter ezizinzileyo zomnye umlomo ngezinye iindlela, kwaye uluhlu olulawulwayo lincinci, ke ekuqaleni, kuya kufuneka uyazi ukuba yeyiphi na imilomo ekulungeleyo. , Ungaqhagamshelana nathi okwangoku, kwaye iinjineli zethu ziya kukunceda ugqibezele ukhetho lwemilomo yombhobho.

Zininzi iindlela zokulawula imeko yokusebenza komlomo. Eyokuqala kukulawula umlomo ngokuvula okanye ukucima impompo, okanye ukutshintsha isantya sempompo. Le ndlela sesona silula solawulo lwemilomo silula sisitshizi. Inkqubo yesekethe elawula impompo yamanzi inokulawula imeko yokusebenza komlomo, kodwa ukusilela kwale ndlela yolawulo nako kuyabonakala. Okokuqala, ixesha lokuphendula liyacotha, kwaye isiphumo solawulo oluchanekileyo alunakufezekiswa. Le ndlela ayinakwenzeka, kwaye ixesha lokuphendula elincinci liya kutshiza amanzi ngaphandle kwesikhongozeli. Nangona kunjalo, ngenxa yexabiso eliphantsi, ukulula kunye nokuthembeka kwale ndlela, kufanelekile ukuba isetyenziswe kwimimandla engadingi ulawulo oluchanekileyo, njengokucoca umphezulu wamalungu, unyango langaphambi kokutyabeka, uvavanyo lweMvula, ukonakaliswa komhlaba kunye nokususwa, njl.

Ukuba ufuna ukulawula ngokuchanekileyo imeko yombhobho, inkqubo yokutshiza iya kuba nzima kakhulu, kwaye kuya kufuneka ufake izixhobo ezahlukeneyo zenzwa, iiveluvu zentsimbi kunye nezinye izinto. Umzekelo, ukuba ufuna ukulawula ngokuchanekileyo ukufuma elabhoratri, kufuneka isivamvo sokufuma ukuqokelela ukufuma okukufutshane. Kwaye wenze uhlalutyo lwedatha, emva koko ulawule ukuqala nokumisa impompo yamanzi kunye ne-solenoid valve ngokwesiphumo sohlalutyo, ukuze ufezekise injongo yolawulo oluchanekileyo lwemilomo. >.
