Uma sekuyisikhathi sokushintsha izinto zokuvala ezisebenza ngomshini, ukulandela iziqondiso ezifanele kuqinisekisa ukusebenza kahle kakhulu. Abaqhubi kufanele:
- Misa izinqubo zokuphepha eziphelele ngaphambi kokuqala umsebenzi wokufaka uphawu lwemishini yepompo.
- Sebenzisa amathuluzi akhethekile njengezimbobo zokuvala kanye nezinkinobho ze-torque ukuze ushintshe.
- Yenza ukuhlolwa kwangaphambi kokufakwa ukuqinisekisa ukuthi zonke izingxenye zisesimweni esihle.
- Lungiselela ukusebenza kwesikhathi eside ngokuhlaziya izitayela zokusebenza kwesivalo nokusebenzisa amasu okulungisa abikezelayo.
Ngokunamathela kulezi zidingo zokulungisa, abaqhubi bangathuthukisa kakhulu ukuthembeka kanye nesikhathi sokuphila kwezinto zokuvala ezisebenza ngomshini kumaphampu amakhemikhali.
Ukukhetha izinto zokuvala ezifanele zemishini kubalulekile ekuqinisekiseni ukusebenza kahle kanye nobude besikhathi samaphampu amakhemikhali. Izinto ezibalulekile okufanele uzicabangele zifaka:
- Ukuhambisana koketshezi nezinto zokuvala uphawu.
- Izimo zokushisa kanye nengcindezi.
- Ukuklwebheka koketshezi oluphampulwayo.
- Ukusetshenziswa kwezivalo ezimbili ukuze kuthuthukiswe ukuphepha ngoketshezi oluyingozi.
Ukubonisana nochwepheshe kunganikeza iseluleko esiklanyelwe ukusetshenziswa okuthile. Le ndlela isiza ekugwemeni ukwehluleka kokuvala kusenesikhathi futhi iqinisekisa ukusebenza kahle. Ngokubeka lokhu kuqala, abaqhubi bangathuthukisa ukuthembeka kwezinhlelo zabo zokupompa.
Imibuzo Evame Ukubuzwa
Kuyini uphawu lomshini?
I-mechanical seal iyithuluzi elivimbela ukuvuza koketshezi phakathi kwezingxenye ezimile nezijikelezayo kumaphampu. Iqukethe ubuso obubili obuyinhloko bokuvala obudala isithiyo, okuqinisekisa ukusebenza kahle nokunciphisa ukungcoliswa kwemvelo.
Ngingazi kanjani ukuthi iyiphi into yokuvala okufanele ngiyikhethe?
Ukukhetha izinto zokuvala ezifanele kuncike ezintweni ezifana nokuhambisana koketshezi, izinga lokushisa, ingcindezi, kanye nokuguguleka. Ukuhlola lezi zici kuqinisekisa ukusebenza kahle kanye nobude besikhathi sokuvala komshini ohlelweni lwakho oluthile.
Kufanele ngihlole kangaki izivalo zemishini?
Ukuhlolwa okuvamile kufanele kwenzeke okungenani njalo ngenyanga. Abaqhubi kufanele bahlole izimpawu zokuguguleka, ukuvuza, kanye nokuqondana okufanele. Ukutholwa kwezinkinga kusenesikhathi kungavimbela isikhathi esibizayo sokungasebenzi futhi kwandise isikhathi sokuphila kwezivalo.
Ngingakwazi yini ukuzishintsha izivalo zomshini?
Nakuba kungenzeka ukushintsha izivalo zemishini ngokuzimela, ukuqeqeshwa okufanele namathuluzi kubalulekile. Ukulandela iziqondiso zomkhiqizi kanye nezinqubo zokuphepha kuqinisekisa ukufakwa okuphumelelayo futhi kunciphisa ingozi yamaphutha.
Yiziphi izimbangela ezivamile zokwehluleka kokuvala ngomshini?
Izimbangela ezivamile zokwehluleka kophawu lomshini zifaka phakathi ukufakwa okungafanele, ukungahleleki kahle, ukungahambisani kwamakhemikhali, kanye nokushisa noma ingcindezi eyeqile. Ukulungiswa nokuhlolwa njalo kungasiza ekuboneni nasekunciphiseni lezi zinkinga.
