phau ntawv hwj chim standard ob txoj kev rooj vag valve

Kev poob qis vim cov khoom siv thiab tsis ua haujlwm yog tus nqi rau kuv cov neeg ua haujlwm, raug nqi ntau lab daus las hauv kev lag luam poob txhua xyoo.Qhov tseeb, kev saib xyuas feem ntau suav nrog ntau dua 30-50% ntawm kuv cov nqi ua haujlwm tag nrho. Rau kev ua haujlwm mining uas cia siab rau Riam Gate Valves (KGVs), kev hloov lub valve yog qhov tshwj xeeb tshaj yog kim, vim tias kev tshuaj xyuas thiab kev kho yuav tsum tau cais cov kab thiab tshem tawm lub valve tag nrho ntawm cov kav dej. Kev khiav hauj lwm cov peev nyiaj tau txwv ntxiv los ntawm cov khoom seem thiab cov nqi cia: txo qis qis thaum lub sijhawm hloov pauv, cov mines feem ntau tuav cov khoom muag tag nrho ntawm cov khoom hloov pauv.Yog li thaum KGVs muaj ntau, lawv kuj nthuav qhia ntau qhov mob rau kev ua haujlwm tsuas. Hauv tsab xov xwm no, peb piav qhia txog cov txheej txheem kev saib xyuas KGV thiab qhia txog cov txheej txheem thiab cov txiaj ntsig tom qab "on-line" thev naus laus zis tshiab uas tau hloov pauv txoj kev mines mus kom ze thiab tswj kev siv nyiaj txiag. Tau ntau xyoo lawm, cov mines tau siv flanged disc lossis lug KGVs los tswj cov dej ntws ntawm cov slurry tsis tshua muaj siab vim nws tau xa los ntawm ntau yam khoom siv rau kev ua cov nroj tsuag.KGVs hnav tawm thaum lub sijhawm ua haujlwm, yog li kev saib xyuas tsis tu ncua yuav tsum tau txo qis kev pheej hmoo ntawm kev tsis ua haujlwm tam sim ntawd thiab unplanned system downtime.Qhov kev tu ncua ncua yog nyob ntawm qhov loj me me ntws los ntawm qhov system, feem pua ​​​​ntawm cov khib nyiab uas muaj nyob hauv cov kua dej thiab nws cov dej ntws. Thaum KGV yuav tsum tau kho lossis hloov, tag nrho lub valve yuav tsum tau muab tshem tawm los ntawm cov kav dej rau kev tshuaj xyuas.Qhov txheej txheem no feem ntau siv sijhawm ob peb teev ib lub valve.Rau qhov haujlwm loj, hloov inevitably ua rau cov hnub poob qis thiab txo cov khoom tsim tau. Tab sis ua ntej cov txheej txheem tshuaj xyuas tuaj yeem pib, cov ductwork yuav tsum raug kaw thiab cais tawm los ntawm cov txheej txheem tagout / kaw kom raug raws li kev cai hauv xeev kev noj qab haus huv thiab kev nyab xeeb.Txhua qhov hluav taws xob lossis huab cua sib txuas rau lub valve actuator yuav tsum raug txiav, thiab nyob ntawm qhov loj me. thiab qhov hnyav ntawm lub valve, cov khoom siv sib dhos yuav tsum tau cais tawm ntawm qhov system.Nws kuj tseem yuav tsum tau txiav cov yeeb nkab lossis tshem tawm cov coupling vim corrosion ntawm flange bolts vim slurry to los yog paug tawm hauv qab ntawm lub valve. . Tom qab tshem tawm lub qub qub, lub valve tshiab yuav tsum tau muab tso rau hauv nws qhov chaw.Txawm li cas los xij, kom tsis txhob muaj kev saib xyuas qeeb, ntau lub mines nqis peev hauv qhov chaw hloov pauv cov khoom lag luam, uas feem ntau txhais tau tias npaj ib qho hloov pauv rau txhua lub valve hauv lawv cov kav dej. Txawm li cas los xij, xav txog. ntau pua lub li qub nyob rau hauv ib lub mine system, kev nqis peev hauv kev hloov lub valve thiab kev cia khoom yuav luag sib npaug ntawm cov khoom siv ntawm cov khoom siv hnyav siv los khawb cov khoom siv.Tshwj xeeb tshaj yog rau cov neeg tsim khoom kub thiab lwm yam khoom muaj txiaj ntsig zoo, lub sij hawm tus nqi ntawm kev kho valve. tuaj yeem yog qhov tseem ceeb. Tau ntau xyoo, cov neeg ua haujlwm kuv tau hu rau kev sib tw thiab pheej yig dua rau cov qauv KGVs.Nyob rau hauv txoj kev xav, lub teeb yuag thiab pheej yig valve yuav ua rau kev kho yooj yim dua thiab tsis tshua muaj kev phom sij rau cov neeg ua haujlwm yam tsis muaj kev cuam tshuam txog kev siv nyiaj txiag.Txawm li cas los xij, qhov kev txhim kho me me no rau kev siv thev naus laus zis thev naus laus zis tsis ua haujlwm. hais txog qhov txiaj ntsig zoo tshaj plaws ntawm kev saib xyuas valve: tas li downtime thiab kev hloov pauv ntawm cov peev txheej los ntawm cov haujlwm tau txais txiaj ntsig mus rau kev kho. Tom qab ntawd, xyoo 2017, KGV thev naus laus zis tshiab tau tsim tshwj xeeb rau kev lag luam mining los muab qhov kuv cov tswv lag luam xav tau tiag tiag - nce cov khoom tsim tau. Nrog rau "hauv-kab" tsim tshiab uas ua kom lub valve ntsia thoob plaws hauv lub voj voog tu, cov neeg siv kev paub txog li. 95% tsawg txij nkawm downtime, thaum txuag tau mus txog 60% nyob rau hauv txhua xyoo valve tu nqi. Cov khoom siv ntawm lub valve - suav nrog cov riam stainless hlau, cov rooj zaum polyurethane, cov qog, cov riam foob thiab lwm yam khoom siv - yog encapsulated nyob rau hauv ib lub rooj zaum valve cartridge cov khoom siv, ua kom yooj yim kho. thiab hloov nws nrog lub lim dej tshiab-thaum lub valve tseem ntsia hauv kab. Txoj hauv kev no rau KGV kev saib xyuas muab cov txiaj ntsig ntawm ntau theem.Nws tsis tas yuav tshem tawm tag nrho lub valve los ntawm cov kav dej, tshem tawm lub sijhawm tseem ceeb.Tsis zoo li kev tuav ib lub valve uas feem ntau yuav siv sij hawm, cov khoom siv lim dej ntawm KGV tshiab tuaj yeem ua tau. tshem tawm thiab hloov hauv ob peb kauj ruam yooj yim hauv tsawg li 12 feeb. Tsis tas li ntawd, KGV online kuj tseem txo cov kev pheej hmoo ntawm kev saib xyuas rau cov neeg ua haujlwm.Tshwj xeeb ib qho kev sib sib zog nqus - lub cartridge - txo qhov kev xav tau ntawm rigging nrog hnyav chains thiab pulleys uas viav vias hla tus tuav lub taub hau. Cov txheej txheem txij nkawm tshwj xeeb no tshem tawm qhov xav tau los tso lub valve thib ob ntawm qhov chaw tos txais.Qhov tseeb, kev nqis peev hauv cov khoom seem tuaj yeem txo qis heev thiab feem ntau yuav luag tshem tawm. Ntxiv nrog rau txoj kev txhim kho no, nws kuj tau lees paub tias qhov kev ua tau zoo ntxiv tuaj yeem ua tiav los ntawm kev nthuav dav tag nrho lub neej ntawm lub valve thiab, thaum kawg, lub sijhawm ntawm kev saib xyuas mus rau qhov kawg, qhov hnav-tiv taus spool yog tsim. nrog lub rooj zaum polyurethane (10 npaug siab dua li roj hmab) thiab cov cuab yeej uas ze li plaub npaug ntawm cov khoom qub, muab kev txhim kho kev hnav zoo thiab kev pabcuam lub neej piv rau cov qauv tsim. Nyob rau hauv txhua rooj plaub, kev kho lub valve uas ib zaug yuav tsum tau teev ntawm downtime yuav raug txo mus rau feeb los ntawm kev siv nyob rau hauv-kab valve technology.Rau mines nrog pipeline systems uas muaj pua pua lub li qub, txhua xyoo kev nyab xeeb thiab nqi-zoo ntawm in-line KGV technology tau. yuav tsum txiav txim siab. Cov cib fim rau hauv-kab KGVs muaj nyob txhua qhov chaw cov kav dej tau tsim los rau kev sib tsoo, suav nrog cov slurries, flotation cells, cyclones thiab tailings. Raws li cov tshuab slurry txuas ntxiv txhim kho los tswj cov qib siab dua ntawm cov ntsiab lus ntawm cov khoom siv, cov nqi ntws thiab cov siab, KGVs yog ib qho tseem ceeb ntawm kev ua haujlwm.
