Ukukhetha izivalo ezifanele zemishini kubalulekile ekusebenzeni kahle kwephampu, ikakhulukazi uma ucabangela i-OEMuphawu lomshiniizinketho zokufaka esikhundleni. Izivalo zekhwalithi ephezulu zithuthukisa kakhulu ubude besikhathi nokusebenza kahle kwamaphampu e-Grundfos ne-Flygt. Isibonelo, izifundo zibonisa ukuthi izivalo zemishini zekhwalithi ephezulu zinciphisa izidingo zokulungisa kanye nezindleko zesikhathi sokungasebenzi, okwenza zibe yi-enye indlela engabizi kakhulu esikhundleni sezitifiketi zegama lomkhiqizoLokhu kubaluleke kakhulu ezindleleni ezibalulekile njengokuphathwa kwamanzi angcolile, laphouphawu lomshini lwamaphampu amanzi angcolilekubalulekile. Ukukhetha ngokucophelelaizivalo zemishini ezilingana kahle namaphampu ezimboniKubalulekile ukuvimbela isikhathi sokungasebenzi esibizayo esibangelwa ukwehluleka kophawu, njengoba cishe u-13% wokwehluleka kophawu lwemishini kuvela ezinkingeni eziyisisekelo. Ngaphezu kwalokho, abasebenzisi abaningi bayazibuza, “Ingabe ukusebenzisa izivalo zemishini ezingezona ezangempela ze-OEM kuyayithinta iwaranti yephampu?"Kubalulekile ukucabangela lokhu lapho ukhetha ukuqinisekisa ukuthobela imithetho kanye nokuvikelwa kwemishini yakho."
Izinto Ezibalulekile Okufanele Uzicabangele
- Khetha uhlobo olufanele lwesivalo somshini. Izivalo ezilodwa zingabizi kakhulu uma zisetshenziswa ngendlela engenangozi, kanti izivalo eziphindwe kabili zinikeza ukuphepha okuthuthukisiwe koketshezi olubolayo.
- Cabanga ngezimo zokusebenza ezifana nokushisa kanye nengcindezi. Khetha izisimbiso ezihambisana nalezi zici ukuqinisekisa ukuthembeka kanye nobude besikhathi.

Ngokuqinisekisa ukuthi ihambisana kahle, abaqhubi banganciphisa ingozi yokuvuza nokungcola, banciphise izindleko zokulungisa, futhi bathuthukise ukusebenza kahle kwephampu iyonke.
Amaphutha Okukhetha Okuvamile Ekushintsheni Kwesivalo Se-OEM Mechanical
Ukungazinaki Imininingwane Yomkhiqizi
Elinye lamaphutha abaluleke kakhulu ekukhetheni ukushintshwa kwe-OEM mechanical seal ukunganaki imininingwane yomkhiqizi. Ukunamathela kulezi ziqondiso kuqinisekisa ukufakwa, ukuhambisana, kanye nokugcinwa okufanele. Lo mkhuba uvimbela ukuvuza kanye nokuguguleka ngaphambi kwesikhathi. Ukusebenza ngaphakathi kwemingcele ethile yokucindezela kanye nokushisa kukhulisa impilo yesevisi ye-seal. Ukuhlolwa njalo kusiza ekutholeni izinkinga ezingaba khona ngaphambi kokuba zikhule zibe ukwehluleka okubizayo.
Imiphumela Yokunganaki Imininingwane:
- Izindleko ezengeziwe ngenxa yokwehluleka kokuvala ngaphambi kwesikhathi.
- Izindleko zokulungisa eziphakeme ngenxa yokulungiswa njalo.
- Kulahleke isikhathi sokukhiqiza ngenxa yokuvalwa okungalindelekile.
- Ukulimala kwedumela ngenxa yokubuyiselwa kwemikhiqizo.
- Izinkinga zokuthobela imithetho eziholela ezinhlawulweni.
- Ukwanda kokuvuza kanye nokulahleka komkhiqizo ngenxa yoketshezi olungahambisani.
- Izingozi zokuphepha kanye nezingozi zemvelo.
Ukubheka Ikhwalithi Yezinto Ezibalulekile
Ikhwalithi yezinto ezibonakalayo idlala indima ebalulekile ekuqineni nasekusebenzeni kwezivalo zomshini. Izinto ezisezingeni eliphezulu, njengeze-ceramics ezakhiwe ngobunjiniyela kanye nezinsimbi ezingagqwali, zimelana nezimo ezinzima. Isibonelo, izivalo zomshini zinikeza ukumelana okuhle kakhulu nokugqwala kodwa zingaphuka ngaphansi kokushaqeka kokushisa. Ngokuphambene nalokho, i-silicon carbide inikeza ubulukhuni obuphezulu kanye nokuqhuba ukushisa, okwenza kube kuhle kakhulu ekusetshenzisweni okusheshayo.
Ukusebenzisa izinto ezisezingeni eliphansi kungaholela emiphumeleni emibi kakhulu:
- Ukuvuza okwandisiwe okuvela ezivalweni zemishini kunciphisa isikhathi sokusebenza kwemishini.
- Ukusebenza kahle kwesistimu iyonke kanye nokuthembeka kwayo kuye kwaphazamiseka.
- Izindleko zokulungisa eziphakeme ngenxa yokulungiswa njalo.
Ukwehluleka Ukucabangela Izidingo Zesicelo
Ukwehluleka ukucabangela izidingo ezithile zesicelo kungaholela emaphutheni amakhulu ekukhetheni uphawu lwemishini. Abaqhubi kumele bavumelanise ukwakheka kophawu nezingcindezi zesistimu kanye namazinga okushisa ukuze bagweme ukwehluleka. Ngaphezu kwalokho, ukuhambisana kwezinto kubalulekile; uketshezi olungahambisani lungaholela ekuwohlokeni kophawu, kudingeke ukuthi kushintshwe.
| Izici Zokukhetha Ezibalulekile | Imiphumela |
|---|---|
| Izimo Zokusebenza | Kumelwe kuhambisane nomklamo wesivalo nezingcindezi zesistimu kanye namazinga okushisa ukuze kugwenywe ukwehluleka. |
| Ukuhambisana kwezinto ezibonakalayo | Uketshezi olungahambisani lungabangela ukuwohloka kwesivalo, okudinga ukushintshwa. |
| Ukulawulwa Kwemvelo | Ukungazinaki lezi zinto kungabangela ukuncipha kokuphila kwe-seal naphezu komklamo omuhle kakhulu. |
Ngokuqonda izidingo ezithile zezicelo zabo, opharetha bangakhetha izivalo ezifanele kakhulu, baqinisekise ukuthembeka nokusebenza kahle ezinhlelweni zabo zokupompa.
Ukukhetha izisimbozo ze-OEM ezisezingeni eliphezulu kubalulekile ekugcineni ukusebenza kanye nobude besikhathi samaphampu e-Grundfos kanye ne-Flygt. Izici ezibalulekile okufanele uzicabangele zifaka:
- Izinhlobo zezimbobo, njengezimbobo zodwa, ezimbili, kanye nezimbobo zekhatriji.
- Izimo zokusebenza, okuhlanganisa izinga lokushisa, ingcindezi, kanye nokuhambisana koketshezi.
- Izilinganiso ezinembile ukuqinisekisa ukulingana okufanele.
- Amaphutha avamile, njengokungazinaki izincazelo zomkhiqizi kanye nekhwalithi yezinto zokwakha.
Ukuhlolwa njalo, ukuhlanza, kanye nokugcotshwa okufanele kubalulekile ukuze kusebenze kahle. Ngokubeka phambili ikhwalithi ekufakweni kabusha kwe-OEM mechanical seal, opharetha bangathuthukisa ukuthembeka futhi banciphise izindleko zokulungisa, baqinisekise ukusebenza kahle kwephampu iminyaka ezayo.
