I-manual power standard indlela emibili ye-valve yesango

Ukuphelelwa yisikhathi kwesistimu ngenxa yokuguga nokwehluleka kwemishini kubiza kakhulu kubaqhubi bezimayini, kubiza izigidi zamadola ekukhiqizeni okulahlekile unyaka ngamunye.Eqinisweni, ukunakekelwa ngokuvamile kubalela ngaphezu kuka-30-50% wesamba sezindleko zokusebenza kwemayini. Emisebenzini yezimayini ethembele kumaValves Esango Lommese (KGVs), ukushintshwa kwamavalvu kubiza kakhulu, njengoba ukuhlola nokulungiswa kudinga ukuhlukaniswa kolayini kanye nokukhipha ivalvu ngokuphelele ohlelweni lwamapayipi.Isabelomali sokusebenza siphinde sincishwe izingxenye eziyisipele nezindleko zokugcina: Ukuze ukunciphisa isikhathi sokuphumula ngesikhathi sokushintsha, izimayini zivame ukugcina iqoqo eligcwele lama-valve okushintsha. Kulesi sihloko, sichaza izinqubo ezivamile zokunakekela i-KGV futhi sigqamisa izinqubo nezinzuzo ngemuva kobuchwepheshe obusha "be-inthanethi" obushintshe indlela izimayini ezibhekana ngayo nokugcina ibhajethi. Sekungamashumi eminyaka, izimayini zisebenzisa i-flanged disc noma ama-lug KGV ukulawula ukugeleza kodaka olubi kakhulu njengoba luhanjiswa ngamapayipi amathuluzi ahlukahlukene ukuya ezimbonini ezicutshungulwayo.Ama-KGV ayaguga ngesikhathi sokusebenza, ngakho ukunakekelwa njalo kuyadingeka ukuze kuncishiswe ingozi yokungaphumeleli kwamavalvu kungazelelwe futhi Isikhathi sokuphumula sesistimu esingahleliwe.Lesi sikhathi sokunakekela sincike kusayizi wezinhlayiyana ezigeleza ohlelweni, iphesenti lokuqinile okuqukethwe oketshezini kanye nezinga lokugeleza kwalo. Lapho i-KGV idinga ukulungiswa noma ukushintshwa, i-valve yonke kufanele ikhishwe ohlelweni lwamapayipi ukuze ihlolwe.Le nqubo ngokuvamile ithatha amahora amaningana nge-valve ngayinye.Kumaphrojekthi amakhulu okulungisa, ukushintshwa ngokungenakugwenywa kubangela izinsuku zokungasebenzi kwesistimu nokunciphisa ukukhiqiza. Kodwa ngaphambi kokuthi inqubo yokuhlola iqale, imigudu kufanele ivalwe futhi ihlukaniswe ngezinqubo ezifanele zokuthibela/ukuvala ngokuhambisana nemithetho yesifundazwe yezempilo nokuphepha eyisibopho.Noma yikuphi ukuxhunywa kukagesi noma komoya ku-actuator yesivalo kufanele kunqanyulwe, futhi kuye ngosayizi. kanye nesisindo se-valve, imishini yokuhlanganisa ingase idingeke ukuze ihlukanise nesistimu.Kungase futhi kudingeke ukusika ipayipi noma ukususa ukuhlanganisa ngenxa yokugqwala kwe-flange bolts ngenxa yokuvuza kwe-slurry noma ukukhishwa kusuka phansi kwe-valve. . Ngemva kokukhipha i-valve endala, i-valve entsha idinga ukufakwa endaweni yayo.Ukugwema ukubambezeleka kokulungisa, izimayini eziningi zitshala imali ekufakweni kwe-valve yokushintshanisa endaweni, okuvame ukusho ukubeka i-valve eyodwa esikhundleni se-valve ngayinye ohlelweni lwazo lwamapayipi.Nokho, ngokucabangela amakhulukhulu amavalvu ohlelweni olulodwa lwemayini, ukutshalwa kwezimali ekushintsheni ama-valve nokugcinwa kwawo kucishe kulingane nenani lempahla yezinto zokusebenza ezinzima ezisetshenziselwa ukumba impahla. kungaba okubalulekile. Sekuyiminyaka, abaqhubi bezimayini bafuna izindlela ezilula nezishibhile esikhundleni sama-KGV avamile. Ngokombono, ivalvu engasindi futhi ethengekayo ingenza ukugcinwa kube lula futhi kungabi yingozi kubasebenzi ngaphandle kokuphula isabelomali sokusebenza. ukubhekana nemiphumela ebiza kakhulu yokulungiswa kwama-valve: isikhathi sokuphumula esiqhubekayo kanye nokuphambukiswa kwezinsiza kusuka emisebenzini enenzuzo kuya ekulungisweni. Kwathi ngo-2017, ubuchwepheshe obusha be-KGV bathuthukiswa ngokukhethekile ukuze imboni yezimayini inikeze lokho abaqhubi bezimayini abakufunayo ngempela - ukwanda kokukhiqiza. Ngomklamo omusha "ongaphakathi" ogcina i-valve ifakiwe kuwo wonke umjikelezo wokulungisa, abasebenzisi bahlangabezana nokufika. I-95% yesikhathi sokuphumula sesondlo esincane, kuyilapho ilondoloza kufika ku-60% ezindlekweni zonyaka zokulungisa ama-valve. Izingxenye ezigugile zamavalvu - okuhlanganisa imimese yensimbi engagqwali, izihlalo ze-polyurethane, izindlala ezipakishwayo, izigxivizo zommese nezinye i-hardware - zimbozwe kukhithi ye-valve yesihlalo esisodwa, okwenza kube lula kakhulu ukulungisa. futhi esikhundleni salo ufake isici esisha sokuhlunga-ngenkathi i-valve isalokhu ifakwe emgqeni. Le ndlela yokunakekela i-KGV inikeza izinzuzo emazingeni amaningana.Asikho isidingo sokususa i-valve yonke ohlelweni lwamapayipi, kuqedwe isikhathi esibalulekile sokuphumula.Ngokungafani nokugcina i-valve eyodwa evamile ngokuvamile ethatha amahora amaningi, isici sokuhlunga esisebenzisekayo se-KGV entsha singaba isusiwe futhi yashintshwa ngezinyathelo ezimbalwa nje ezilula emizuzwini eyi-12. Ukwengeza, i-KGV eku-inthanethi iphinde inciphise izingozi zokunakekela abasebenzi.Ukushintsha ingxenye eyodwa kuphela engasindi - i-cartridge - kunciphisa kakhulu isidingo sokugetshengwa ngamaketanga asindayo kanye nama-pulleys anyakazayo phezu kwekhanda lomnakekeli. Le nqubo yokulungisa eyingqayizivele iqeda isidingo sokubeka i-valve yesibili kokubekwe eceleni.Eqinisweni, ukutshalwa kwezimali ku-inventory eyisipele kungancishiswa kakhulu futhi ngokuvamile kucishe kuqedwe. Ngokungeziwe kule nqubo yokulungisa ethuthukisiwe, kuphinde kwaqashelwa ukuthi enye inzuzo yokukhiqiza ingafinyelelwa ngokunweba impilo yonke yokuguga kwevalvu futhi, ekugcineni, nesikhathi phakathi kwemijikelezo yokulungisa. Ukuze kufezeke lokhu, i-spool engagugi iklanyelwe. enesihlalo se-polyurethane (izikhathi ezingu-10 ngaphezu kwerabha) kanye nethuluzi eliwugqinsi cishe ngokuphindwe kane kunama-valve avamile, elihlinzeka ngokuthuthukisiwe ukumelana nokugqoka nokuphila kwesevisi uma kuqhathaniswa nemiklamo evamile. Kuzo zonke izimo zokusetshenziswa, ukugcinwa kwamavalvu okwake kwadinga amahora okungasebenzi kungancishiswa kube amaminithi ngokusebenzisa ubuchwepheshe be-valve esemgqeni. Ezimayini ezinesistimu yamapayipi aqukethe amakhulukhulu amavalvu, ukuphepha konyaka kanye nokusebenza kahle kwezindleko kobuchwepheshe be-in-line KGV kube kukhulu. Amathuba ama-KGV akulayini akhona noma yikuphi lapho amasistimu amapayipi akhelwe khona amasevisi okugaya, okuhlanganisa ama-slurries, amaseli e-flotation, ama-cyclone nama-tailings. Njengoba izinhlelo ze-slurry ziqhubeka nokuguquguquka ukuze zibambe amazinga aphezulu okuqukethwe okuqinile, amazinga okugeleza nezingcindezi, ama-KGV ayingxenye ebalulekile ekhulayo yesistimu yokusebenza.Abaqhubi bezimayini abasebenzisa i-KGV eku-inthanethi banganciphisa isigameko nezindleko zokuguga nokugcinwa kwamavalvu. I-Canadian Mining Magazine inikeza ulwazi mayelana nezimayini ezintsha zaseCanada kanye nezitayela zokuhlola, ubuchwepheshe, imisebenzi yezimayini, intuthuko yezinkampani kanye nemicimbi yezimboni.
