Ulwazi lwe-Pump - Izinhlobo ezivame ukusetshenziswa ze-shaft seal zamaphampu we-slurry
Ekuhlukaniseni amaphampu, ngokwezimo zawo zokulethwa kodaka, sibhekisela kumaphampu afanele ukuthutha uketshezi (okumaphakathi) aqukethe izinto eziqinile ezimisiwe njengamaphampu anodaka. Njengamanje, iphampu ye-slurry ingenye yezinsiza ezibalulekile ezinqubweni ezihlukahlukene zobuchwepheshe ezifana nokuzuza kwe-ore, ukulungiswa kwamalahle, ukukhipha i-sulfurization, kanye nokuphakelwa komshini wokuhlunga. Njengoba abantu benaka kakhulu ukuvikelwa kwemvelo, ukubekwa uphawu kwamaphampu anodaka nakho kuyanakwa kakhulu.
Kunezinhlobo ezintathu eziyinhloko zama-shaft seal zamaphampu a-slurry: uphawu lokupakisha, uphawu lwe-expeller, kanye ne-mechanical seal. Lezi zinhlobo ezintathu zama-shaft seal zinezinzuzo zazo, ezethulwa ngale ndlela elandelayo:
I-Packing Seal: Uphawu lokupakisha lwephampu e-slurry luncike ekusebenzeni okuthambile nokuqinile phakathi kokupakisha nomkhono we-shaft ukuze kuzuzwe umphumela wokuvala. Uphawu lokupakisha ludinga ukwengeza amanzi ophawu lwe-shaft, ingcindezi okufanele idlule ingcindezi yokukhipha impompo ye-slurry. Le ndlela yokubeka uphawu kulula Ukubuyisela futhi isetshenziswa kakhulu ezitshalweni zokugqoka insimbi kanye nezitshalo zokuwasha amalahle.
I-Expeller Seal: I-expeller seal yepompo ye-slurry incike ekucindezelweni okukhiqizwa umxoshi ukuze kuzuzwe umphumela wokuvala. Le ndlela yokuvala isetshenziswa lapho umsebenzisi eshoda ngemithombo yamanzi.
Mechanical Seal: Isigxivizo esisebenza ngomshini sincike ekuxhumaneni okuseduze phakathi kweringi ejikelezayo nendandatho emile ekuqondeni kwe-axial ukuze kuzuzwe inhloso yokuvala. Isigxivizo esisebenza ngomshini singavimbela amanzi ukuthi angavuzi futhi sithandwa kakhulu kuma-concentrator asekhaya nasezitshalweni zikagesi. Kodwa-ke, kuyadingeka ukuvikela indawo engqubuzanayo ukuze ugweme ukuhuzuka ngesikhathi sokufakwa. Izigxivizo zemishini ngokuvamile zihlukaniswa zibe izigxivizo zemishini eyodwa kanye nezigxivizo ezimbili ezisebenza ngomshini. Kulesi sigaba, sincoma uphawu olulodwa lwemishini ngamanzi ashisayo ezitshalweni zokuhlukanisa amaminerali. Lolu hlobo lwe-mechanical seal luye lwasetshenziswa kabanzi. Nakuba izigxivizo ezisetshenziswayo ezingenawo amanzi ahlanjululwayo nazo zituswa abakhiqizi bezimpawu zemishini, azilungile ekusetshenzisweni kwensimu. Ngaphezu kwalezi zigxivizo ezintathu ezingenhla ezivame ukusetshenziswa, kukhona ne-shaft seal, ebizwa ngokuthi "L" -shaped shaft seal kule mboni. Lolu hlobo lwe-shaft seal ngokuvamile lusetshenziswa kumaphampu amakhulu noma amakhulu ama-slurry kodwa akuvamile ukusetshenziswa kumaphampu amancane naphakathi nendawo.
Ngakho-ke, ekukhethweni kwamaphampu e-slurry, akufanele kucatshangelwe kuphela ukucaciswa kokusebenza kwepompo, kodwa ukukhethwa kwe-shaft seal nakho kubaluleke kakhulu. Ukukhetha uphawu lwe-shaft olufanelekile lwamaphampu a-slurry, ngokusekelwe ezicini zendlela ehanjiswayo endaweni kanye nezimo zokusebenza, kuzokwandisa isikhathi sokusebenza okuthembekile kwepompo futhi kunciphise isikhathi sokuphumula esibangelwa ukushintshwa kwe-shaft seal. Ngale ndlela, akuzona kuphela izindleko eziphelele zobunikazi ezincishisiwe kakhulu, kodwa futhi ukusebenza kahle kokusebenza kuthuthukiswa kakhulu.
