Isipiliyoni: Ukulungiswa kweHlukanisa Ikesi Pump Ukugqwala Nokulimala Kokuguguleka

Kwezinye izinhlelo zokusebenza, ukugqwala kanye/noma ukuguguleka akunakugwenywa. Niniicala lokuhlukanisaamaphampu athola ukulungiswa futhi alimale kabi, angase abukeke njengensimbi eyizinsimbi, kodwa ngamasu okubuyisela afanele, ngokuvamile angabuyiselwa ekusebenzeni kwawo kwasekuqaleni noma okungcono. Ukulimala okubangelwa ukugqwala kanye/noma ukuguguleka kungenzeka ezingxenyeni zephampu ezimile kanye nakuma-impeller ajikelezayo.

QAPHELA: Ukulimala kwe-Cavitation kuwuhlobo lomonakalo wokuguguleka.

1. Ukulungisa Ukugqoka

Izindlela zokulungisa ezivamile zokulimala kwezingxenye zensimbi zihlukaniswe ngezigaba ezintathu: ukulungiswa kokugqoka, ukulungiswa kwemishini kanye nokulungiswa kwe-welding. Yiqiniso, ukulungisa okuningi kuhilela inhlanganisela yazo zontathu. Kulezi zindlela ezintathu, ukulungisa ukumboza kuqondile futhi ngokuvamile kulula kakhulu ukukusebenzisa. Kunabahlinzeki abaningi nezinto zokubuyisela ezihlukahlukene eziklanyelwe le njongo ngokuqondile.

2. Mukulungiswa kwemishini

Ukulungiswa kwemishini kuvame kakhulu lapho umthungo uvela iphampu yecala lokuhlukanisa izingxenye zonakele. Njengoba ukuqondanisa kwezingxenye zephampu kungathinteka ngokuqedwa komthungo, ukwakheka okufanele kuyadingeka ukuze kuqinisekiswe ukuthi iphampu ihlangana kahle. Yiqiniso, ukugcinwa kwe-concentricity kanye ne-perpendicularity yezindawo ezingaphezulu kubalulekile. Ukwengeza, lapho ubuso be-spigot senziwa ngomshini ukuze kuqedwe umonakalo, kushintsha indawo ye-axial yokukhwelana kanye nezingxenye ezihlobene.

Uma indawo ye-axial yama-bearings, izimpawu, izindandatho zokugqoka noma ezinye izingxenye zokunemba zithinteka, kungase kudingeke ukulungisa isimo sezingxenye ezifanele, njengokulungisa isikhundla sehlombe lendawo yokubeka endaweni ku-shaft. Uma i-impeller ye iphampu ye-turbine eqondile ifakwe ukhiye we-shaft wendandatho, ukulungisa ubuso bomthungo bengxenye engaguquki kungase kudinge ukukhanda shaft entsha ngendawo yokhiye wendandatho elungisiwe.

3. I-Weldngi Repair

Ukulungisa i-welding kuyindlela efiseleka kakhulu. Izingxenye zephampu ye-Cast (ama-impeller nezingxenye ezimile) zingaba nzima ukuzilungisa ngokushisela. I-Brazing ingase iphumelele, kodwa izingxenye kufanele zishiswe ngokulinganayo, futhi ngisho nalokhu kungabangela ukuphazamiseka. Ukulungiswa okubanzi kokushisela ezingxenyeni kungase kudinge ukusetshenzwa kabusha kwazo zonke izindawo ezinomshini ukuze kuqinisekiswe ukuthi imiphumela yokuhlanekezela iyasuswa.

Isibonelo ukulungiswa kwezindawo zokukhwelana lapho kuhlukaniswaicalaamabhokisi epompo asetshenziswa ezinhlelweni zamanzi ezivamile. Uma indawo yendlu yephampu yokukhwelana ilimele, izinkulungwane ezimbalwa (ama-microns) angashintshwa ukuze kutholwe indawo entsha eyisicaba. Ukuze kuzuzwe ukulingana okufanele ngemva komshini, i-gasket ye-pump ewugqinsi ingafakwa ukunxephezela into esusiwe. Kodwa-ke, lokhu akufanelekile ukugcinwa kwamaphampu wamandla aphezulu. Ukulungiswa kwala maphampu anamandla aphezulu kungaphezu kobubanzi balesi sihloko.

Ukulungisa ukugqwala kanye/noma ukuguguleka komonakalo otholakala ezinsizeni eziningi zamaphampu kuyingxenye ebalulekile yokulungisa iphampu. Uma indawo eyonakele ishiywe ingalungisiwe, inqubo yomonakalo izosheshiswa ngenxa yokwanda kwesiyaluyalu endaweni emagebhugebhu. Indlela echazwe lapha kufanele isize ukuxazulula izimo zenkohlakalo ezivame kakhulu.
