Manual mphamvu muyezo njira ziwiri chipata valavu

Kuwonongeka kwa makina chifukwa cha kutayika kwa zipangizo ndi kulephera kwa zipangizo kumawononga ndalama zambiri kwa oyendetsa migodi, zomwe zimawononga madola mamiliyoni ambiri kuti awonongeke chaka chilichonse. Kwa ntchito zamigodi zomwe zimadalira Knife Gate Valves (KGVs), kusintha ma valve ndi okwera mtengo kwambiri, chifukwa kuyang'anira ndi kukonza kumafuna kupatutsa mzere ndi kuchotsa valavu kwathunthu ku dongosolo la mapaipi. kuchepetsa nthawi yochepetsera panthawi ya kusintha, migodi nthawi zambiri imakhala ndi mndandanda wathunthu wa ma valve olowa m'malo. M'nkhaniyi, tikufotokoza njira zomwe zimagwiritsidwa ntchito pokonzekera KGV ndikuwunikira njira ndi zopindulitsa za "teknoloji" yatsopano yapa intaneti yomwe yasintha momwe migodi imayendera ndikusunga ndalama. Kwa zaka zambiri, migodi yakhala ikugwiritsa ntchito flanged disc kapena lug KGVs kuwongolera kuyenda kwa slurry yowopsa kwambiri chifukwa imayendetsedwa ndi zida zosiyanasiyana kupita kumalo opangira zinthu. zosakonzekera dongosolo downtime.This yokonza imeneyi zimadalira tinthu kukula ikuyenda mwa dongosolo, kuchuluka kwa zolimba zili madzimadzi ndi otaya mlingo. Pamene KGV ikufunika kukonzedwa kapena kusinthidwa, valavu yonse iyenera kuchotsedwa ku dongosolo la mapaipi kuti liwonedwe.Ntchitoyi nthawi zambiri imatenga maola angapo pa valve.Kwa ntchito zazikulu zokonzekera, kusinthidwa mosalephera kumabweretsa masiku a dongosolo lochepetsetsa ndi kuchepetsa zokolola. Koma ntchito yoyang'anira isanayambe, ma ductwork ayenera kutsekedwa ndi kupatulidwa kudzera mu njira zoyenera za tagout / zotsekera molingana ndi malamulo ovomerezeka a zaumoyo ndi chitetezo m'chigawo.Kulumikizana kulikonse kwa magetsi kapena mpweya ku valve actuator kuyenera kutsekedwa, ndipo malingana ndi kukula kwake. ndi kulemera kwa valve, zipangizo zosonkhana zingafunike kuti ziwalekanitse ku dongosolo. Zingakhalenso zofunikira kudula chitoliro kapena kuchotsa kugwirizana chifukwa cha dzimbiri za flange bolts chifukwa cha slurry kutuluka kapena kutulutsa kuchokera pansi pa valve. . Pambuyo pochotsa valavu yakale, valavu yatsopano iyenera kuikidwa m'malo mwake.Kupewa kuchedwa kwa kukonza, migodi yambiri imagulitsa malo osungiramo ma valve, omwe nthawi zambiri amatanthawuza kusunga valavu imodzi m'malo mwa valve iliyonse mu makina awo a mapaipi. mazana a mavavu mu dongosolo limodzi mgodi, ndalama mu valavu m'malo ndi kusungirako pafupifupi wofanana kufufuza mtengo wa zida zolemetsa ntchito pofukula material.Ispecially kwa opanga golide ndi mchere wina wapamwamba-mtengo, mwayi mtengo wa miyambo valavu kukonza zitha kukhala zofunikira. Kwa zaka zambiri, oyendetsa migodi akhala akufuna njira zina zochepetsera komanso zotsika mtengo kuposa ma KGVs ochiritsira. Mwachidziwitso, valavu yopepuka komanso yotsika mtengo imapangitsa kukonza kukhala kosavuta komanso koopsa kwa ogwira ntchito popanda kuphwanya bajeti. kuthana ndi zotulukapo zokwera mtengo kwambiri pakukonza ma valve: kutsika kosalekeza ndi kusokoneza zinthu kuchokera ku ntchito zopindulitsa kupita ku kukonza. Kenaka, mu 2017, teknoloji yatsopano ya KGV inapangidwa makamaka kuti makampani a migodi apereke zomwe oyendetsa migodi akufunadi - kuwonjezeka kwa zokolola. 95% yochepetsera nthawi yokonza, ndikusunga mpaka 60% pamitengo yapachaka yokonza ma valve. Zovala za valve - kuphatikizapo mipeni ya zitsulo zosapanga dzimbiri, mipando ya polyurethane, zotupa zonyamula, zisindikizo za mpeni ndi zida zina - zimayikidwa mu katiriji katoni yokhala ndi mpando umodzi, kumathandizira kukonza bwino. ndi m'malo ndi chinthu chatsopano fyuluta-pamene valavu amakhalabe anaika mu mzere. Njira imeneyi yosamalira KGV imapereka phindu pamagulu angapo.Palibe chifukwa chochotsa valavu yonse kuchokera ku makina opangira mapaipi, kuthetsa nthawi yochepetsetsa kwambiri.Mosiyana ndi kusunga valavu imodzi yachizolowezi yomwe nthawi zambiri imatenga maola, chinthu chogwiritsira ntchito fyuluta cha KGV chatsopano chikhoza kukhala. kuchotsedwa ndi kusinthidwa m'masitepe ochepa chabe mkati mwa mphindi 12 zokha. Kuphatikiza apo, KGV yapaintaneti imachepetsanso zoopsa zokonzekera kwa ogwira ntchito.Kusintha gawo limodzi lokha lopepuka - katiriji - kumachepetsa kwambiri kufunika kokhala ndi unyolo wolemera ndi ma pulleys omwe amagwedezeka pamutu wa wosamalira. Kukonzekera kwapadera kumeneku kumathetsa kufunika koyika valavu yachiwiri pa standby.Zoonadi, ndalama zosungiramo zosungirako zosungirako zimatha kuchepetsedwa kwambiri ndipo nthawi zambiri zimakhala pafupifupi kutha. Kuphatikiza pa kukonza bwino uku, zadziwikanso kuti zopindulitsa zina zitha kupezedwa mwa kukulitsa moyo wakuvala kwa valavu ndipo, pamapeto pake, nthawi yapakati pamayendedwe okonza. yokhala ndi mpando wa polyurethane (nthawi 10 kuposa mphira) ndi chida chomwe chimakhala chokhuthala pafupifupi kanayi kuposa mavavu ochiritsira, chomwe chimapereka kukana kovala bwino komanso moyo wautumiki poyerekeza ndi mapangidwe wamba. Muzochitika zonse zogwiritsidwa ntchito, kukonza ma valve omwe nthawi ina ankafuna maola ochepa amatha kuchepetsedwa kukhala mphindi pogwiritsa ntchito teknoloji ya valve ya mu-line. Kwa migodi yokhala ndi mapaipi okhala ndi mazana a ma valve, chitetezo chapachaka komanso kutsika mtengo kwa teknoloji ya KGV kukhala wochuluka. Mwayi wa ma KGV apamzere umapezeka kulikonse komwe mapaipi amapangidwira ntchito zopera, kuphatikiza ma slurries, ma cell oyandama, mvula yamkuntho ndi michira. Pamene machitidwe a slurry akupitirizabe kusinthika kuti agwirizane ndi kuchuluka kwa zinthu zolimba, kuthamanga ndi kupanikizika, KGVs ndi gawo lofunika kwambiri la machitidwe opangira ntchito. Canadian Mining Magazine imapereka chidziwitso chokhudza migodi yatsopano ya Canada ndi kufufuza, matekinoloje, ntchito zamigodi, chitukuko chamakampani ndi zochitika zamakampani.
