Kev ncaj ncees tus nqi ntawm cov cuab yeej
Feem ntau siv ntawm cov ntsuas no, tab sis nws txoj kev koom tes rau kev tswj hwm yog txwv. Qhov hu ua qhov tsis zoo yog hais txog qhov sib piv ntawm cov khoom siv tsis zoo rau tag nrho cov khoom siv thaum lub sijhawm tshuaj xyuas (cov khoom siv tsis zoo = tus lej ntawm cov khoom tsis zoo / tag nrho cov khoom siv). Cov ntsuas ntawm ntau lub Hoobkas tuaj yeem ncav cuag ntau dua 95%. Qhov laj thawj yog yooj yim heev. Thaum lub sijhawm tshuaj xyuas, yog tias cov cuab yeej ua haujlwm thiab tsis muaj qhov tsis ua haujlwm, nws raug suav tias yog qhov zoo, yog li qhov ntsuas no yooj yim ua tiav. Nws tuaj yeem yooj yim txhais tau tias tsis muaj chaw ntau rau kev txhim kho, uas txhais tau hais tias tsis muaj dab tsi los txhim kho, uas txhais tau hais tias nws nyuaj rau kev txhim kho. Vim li no, ntau lub tuam txhab thov kom hloov kho lub ntsiab lus ntawm qhov ntsuas no, piv txwv li, tawm tswv yim kom kuaj peb zaug ntawm 8th, 18th, thiab 28th ntawm txhua lub hlis, thiab coj qhov nruab nrab ntawm qhov tsis zoo li qhov tsis zoo ntawm lub hlis no. Qhov no yeej zoo dua li kev kuaj ib zaug, tab sis nws tseem yog tus nqi zoo uas tau pom hauv cov dots. Tom qab ntawd, nws tau pom zoo tias cov sij hawm ntawm lub rooj tsis zoo yuav muab piv nrog cov sij hawm ntawm lub rooj sib tham, thiab cov sij hawm ntawm lub rooj tsis zoo yog sib npaug rau cov sij hawm ntawm lub rooj daim ntawv qhia hnub rho tawm tag nrho cov sij hawm ntawm kev ua txhaum thiab kho. Qhov ntsuas no muaj tseeb ntau dua. Tau kawg, muaj kev nce ntxiv hauv cov ntaub ntawv txheeb cais thiab qhov tseeb ntawm cov txheeb cais, thiab kev sib cav txog seb puas yuav txiav tawm thaum ntsib qhov chaw tiv thaiv kev tiv thaiv. Txawm hais tias qhov ntsuas ntawm qhov tsis zoo tuaj yeem cuam tshuam qhov xwm txheej ntawm kev tswj cov cuab yeej nyob ntawm seb nws siv li cas.
Failure Rate Ntawm Cov Khoom Siv
Qhov ntsuas no yooj yim rau kev tsis meej pem, thiab muaj ob lub ntsiab lus: 1. Yog tias nws yog qhov tsis ua haujlwm zaus, nws yog qhov sib piv ntawm tus naj npawb ntawm qhov tsis ua haujlwm rau qhov tseeb pib ntawm cov khoom siv (failure zaus = tus naj npawb ntawm qhov tsis ua haujlwm kaw / qhov tseeb ntawm cov khoom pib); 2. Yog hais tias nws yog qhov tsis ua hauj lwm kaw tus nqi, Nws yog qhov piv ntawm lub downtime ntawm qhov txhaum mus rau qhov tseeb pib-up ntawm cov cuab yeej ntxiv rau lub sij hawm downtime ntawm qhov txhaum (tus downtime tus nqi = lub downtime ntawm qhov txhaum / (lub sij hawm pib-up qhov tseeb ntawm cov khoom + lub sij hawm ntawm downtime ntawm qhov txhaum)) Obviously, downtime tus nqi ntawm qhov txhaum yuav muab piv rau cov xwm txheej tiag tiag.
Muaj Tus Nqi Ntawm Cov Khoom Siv
Nws yog dav siv nyob rau sab hnub poob, tab sis nyob rau hauv kuv lub teb chaws, muaj ob qhov sib txawv ntawm kev npaj lub sij hawm siv tus nqi (tshaj sij hawm siv tus nqi = lub sij hawm ua hauj lwm / lub sij hawm npaj ua hauj lwm) thiab daim ntawv teev sij hawm siv tus nqi (calendar time utilization rate = tiag tiag ua hauj lwm lub sij hawm / daim ntawv teev sij hawm) formulation. Muaj raws li tau hais tseg nyob rau sab hnub poob yog qhov tseeb siv lub sijhawm siv los ntawm kev txhais. Lub sij hawm siv daim ntawv qhia hnub qhia txog kev siv tag nrho ntawm cov cuab yeej, uas yog hais tias, txawm tias cov cuab yeej ua haujlwm hauv ib qho kev hloov pauv, peb suav lub sijhawm ua haujlwm raws li 24 teev. Vim tsis muaj teeb meem txawm tias lub Hoobkas siv cov cuab yeej no los yog tsis, nws yuav siv cov cuab tam ntawm lub lag luam hauv daim ntawv depreciation. Kev npaj siv lub sij hawm qhia txog kev npaj siv cov cuab yeej siv. Yog tias nws ua haujlwm hauv ib qho kev hloov pauv, lub sijhawm npaj yog 8 teev.
Lub Sijhawm Nruab Nrab Nruab Nrab (MTBF) Ntawm Cov Khoom Siv
Lwm qhov kev tsim yog hu ua lub sijhawm nruab nrab tsis muaj teeb meem ua haujlwm "lub sijhawm nruab nrab ntawm cov khoom siv tsis ua haujlwm = tag nrho lub sijhawm ntawm kev ua haujlwm tsis muaj teeb meem nyob rau hauv lub sijhawm sau tseg / tus naj npawb ntawm kev ua tsis tiav". Ntxiv rau qhov downtime tus nqi, nws qhia txog qhov zaus ntawm kev ua tsis tiav, uas yog, kev noj qab haus huv ntawm cov khoom siv. Ib qho ntawm ob qhov ntsuas tau txaus, thiab tsis tas yuav siv cov ntsuas ntsuas los ntsuas cov ntsiab lus. Lwm qhov taw qhia uas qhia txog kev saib xyuas kev ua haujlwm yog txhais tau tias lub sijhawm kho (MTTR) (lub sijhawm nruab nrab ntawm kev kho = tag nrho lub sijhawm siv rau kev saib xyuas hauv lub sijhawm sau tseg / tus naj npawb ntawm kev saib xyuas), uas ntsuas kev txhim kho kev ua haujlwm ntawm kev saib xyuas. Nrog rau kev nce qib ntawm cov cuab yeej siv tshuab, nws qhov nyuaj, kev saib xyuas nyuaj, qhov chaw ua txhaum, qhov nruab nrab ntawm kev ua haujlwm zoo ntawm cov kws kho mob thiab cov khoom siv hnub nyoog, nws yog qhov nyuaj kom muaj tus nqi tseeb rau lub sijhawm txij nkawm, tab sis peb tuaj yeem ntsuas nws qhov nruab nrab thiab kev nce qib raws li qhov no.
Tag Nrho Cov Khoom Siv Tau Zoo (OEE)
Qhov taw qhia uas qhia txog cov khoom siv tau zoo dua, OEE yog cov khoom lag luam ntawm lub sijhawm ua haujlwm, kev ua haujlwm ntawm kev ua haujlwm thiab cov khoom tsim nyog. Ib yam li tus neeg, lub sijhawm ua kom lub sijhawm sawv cev rau tus nqi tuaj koom, qhov kev ua haujlwm ua haujlwm sawv cev rau seb puas yuav ua haujlwm hnyav tom qab mus ua haujlwm, thiab ua kom muaj txiaj ntsig zoo, thiab cov khoom tsim nyog tus nqi sawv cev rau qhov ua tau zoo ntawm kev ua haujlwm, seb puas ua yuam kev ntau zaus, thiab seb txoj haujlwm puas tuaj yeem ua tiav nrog qhov zoo thiab muaj nuj nqis. Cov qauv OEE yooj yim yog tag nrho cov cuab yeej siv tau zoo OEE = cov khoom tsim nyog cov khoom tsim tawm / theoretical tso zis ntawm cov sij hawm ua haujlwm.
Tag Nrho Cov Khoom Siv Tau Zoo TEEP
Cov mis uas zoo tshaj plaws qhia txog cov cuab yeej siv tau zoo tsis yog OEE. Tag Nrho Cov Khoom Siv Tau Zoo TEEP = tsim nyog cov khoom tsim tawm / kev tsim tawm ntawm lub sijhawm, qhov ntsuas no qhia txog kev tswj hwm cov khoom siv tsis raug, suav nrog kev cuam tshuam rau sab saud thiab qis qis, kev lag luam thiab kev txiav txim cuam tshuam, tsis muaj peev xwm ntawm cov cuab yeej siv, kev npaj tsis tsim nyog thiab kev teem caij, thiab lwm yam tuaj tawm. Qhov ntsuas no feem ntau qis heev, tsis zoo saib, tab sis tiag tiag.
Kev tu thiab tswj cov cuab yeej siv
Kuj tseem muaj cov ntsuas ntsuas. Xws li ib-lub sij hawm tsim nyog tus nqi ntawm overhaul zoo, kho tus nqi thiab txij nkawm tus nqi, thiab lwm yam.
1. Tus nqi dhau ib zaug ntawm kev kho dua tshiab yog ntsuas los ntawm qhov piv ntawm cov khoom siv kho dua tshiab raws li cov khoom tsim nyog rau ib qho kev sim ua haujlwm rau tus naj npawb ntawm kev kho dua tshiab. Seb lub Hoobkas txais qhov ntsuas no ua qhov ntsuas qhov ua tau zoo ntawm pab pawg saib xyuas tuaj yeem kawm thiab txiav txim siab.
2. Tus nqi kho yog qhov piv ntawm tag nrho cov kev kho tom qab kho cov khoom siv rau tag nrho cov kev kho. Qhov no yog ib qho kev xav txog qhov zoo ntawm kev saib xyuas.
3. Muaj ntau lub ntsiab lus thiab algorithms ntawm kev saib xyuas tus nqi sib piv, ib qho yog qhov piv ntawm cov nqi tu txhua xyoo rau cov nqi tsim tawm txhua xyoo, qhov sib piv ntawm cov nqi tu txhua xyoo rau tag nrho cov nqi qub ntawm cov cuab tam hauv lub xyoo, thiab lwm qhov yog qhov piv ntawm cov nqi tu txhua xyoo rau tag nrho cov cuab tam hauv lub xyoo Qhov piv ntawm cov nqi hloov pauv yog qhov piv ntawm cov nqi tu txhua xyoo rau tag nrho cov cuab yeej cuab tam tus nqi ntawm lub xyoo. Kuv xav tias qhov kawg algorithm yog txhim khu kev qha. Txawm li cas los xij, qhov loj ntawm tus nqi tu tus nqi tsis tuaj yeem piav qhia qhov teeb meem. Vim tias cov khoom siv tu vaj tse yog ib qho kev tawm tswv yim, uas tsim cov nqi thiab cov khoom siv. Kev nqis peev tsis txaus thiab cov khoom lag luam tseem ceeb poob yuav cuam tshuam rau cov khoom lag luam. Tau kawg, kev nqis peev ntau dhau tsis zoo tagnrho. Nws yog hu ua overmaintenance, uas yog pov tseg. Cov tswv yim tsim nyog yog qhov zoo tagnrho. Yog li ntawd, lub Hoobkas yuav tsum tshawb nrhiav thiab kawm txog qhov kev nqis peev zoo tshaj plaws. Cov nqi tsim khoom siab txhais tau hais tias kev txiav txim ntau dua thiab ua haujlwm ntau dua, thiab cov khoom siv thauj khoom nce ntxiv, thiab qhov kev thov rau kev saib xyuas kuj nce ntxiv. Kev nqis peev hauv qhov tsim nyog piv yog lub hom phiaj uas lub Hoobkas yuav tsum siv zog ua kom tiav. Yog tias koj muaj cov kab hauv qab no, qhov deb dua koj deviate los ntawm qhov ntsuas no, qhov tsawg dua qhov zoo tshaj plaws.
Spare Parts Kev Tswj Xyuas Cov Khoom Siv
Kuj tseem muaj ntau qhov ntsuas, thiab qhov kev hloov pauv ntawm cov khoom seem ntawm cov khoom muag (qhov kev hloov pauv ntawm cov khoom seem ntawm cov khoom seem = kev noj txhua hli ntawm cov nqi seem / cov nyiaj nruab nrab ntawm cov khoom muag txhua hli) yog qhov qhia ntau dua. Nws qhia txog kev txav mus los ntawm cov khoom seem. Yog tias qhov nyiaj ntau ntawm cov khoom lag luam tau rov qab los, nws yuav raug cuam tshuam los ntawm kev hloov pauv. Dab tsi tseem qhia txog kev tswj cov khoom seem yog qhov piv ntawm cov nyiaj seem, uas yog, qhov sib piv ntawm tag nrho cov nyiaj seem rau tag nrho cov nqi qub ntawm cov khoom lag luam. Tus nqi ntawm tus nqi no txawv nyob ntawm seb lub Hoobkas puas nyob hauv lub nroog hauv nruab nrab, seb cov khoom siv tau los, thiab qhov cuam tshuam ntawm cov khoom siv downtime. Yog tias txhua hnub poob ntawm cov khoom siv poob qis yog siab li kaum lab lab yuan, lossis qhov tsis ua haujlwm ua rau muaj kev puas tsuaj loj rau ib puag ncig thiab kev nyab xeeb ntawm tus kheej, thiab lub voj voog ntawm cov khoom seem ntev dua, cov khoom muag ntawm cov khoom seem yuav siab dua. Txwv tsis pub, cov nyiaj tau los ntawm cov khoom seem yuav tsum siab npaum li qhov ua tau. txo. Muaj qhov taw qhia uas tsis tau pom los ntawm tib neeg, tab sis nws yog ib qho tseem ceeb heev hauv kev tswj xyuas niaj hnub no, uas yog, kev saib xyuas lub sij hawm siv zog (kev tu lub sij hawm siv sij hawm = kev saib xyuas kev cob qhia teev / tu neeg sij hawm). Kev cob qhia suav nrog kev paub txog cov khoom siv, kev siv thev naus laus zis, kev tshaj lij thiab kev tswj hwm kev tswj hwm thiab lwm yam. Qhov ntsuas no qhia txog qhov tseem ceeb thiab kev siv peev ntawm cov lag luam hauv kev txhim kho cov neeg ua haujlwm tu cov neeg ua haujlwm zoo, thiab tseem cuam tshuam ncaj qha rau theem ntawm kev saib xyuas kev muaj peev xwm.
