MTBF yog dab tsi? | Lub Sijhawm Ua Ntej Tsis Ua Haujlwm
Introduction
MTBF, los yog Lub Sij Hawm Ua Ntej Ua Ntej, yog qhov ntsuas ntawm lub sijhawm nruab nrab ntawm qhov system lossis cov khoom siv tuaj yeem ua haujlwm ua ntej nws ua tsis tiav. MTBF yog ib qho kev ntsuas tseem ceeb hauv kev saib xyuas thiab kev txhim kho kev ntseeg siab, vim nws pab cov koom haum nkag siab txog qhov kev cia siab ntawm lub cev thiab npaj rau kev hloov lossis kho.
MTBF suav li cas?
MTBF yog xam los ntawm kev faib tag nrho lub sijhawm ua haujlwm ntawm lub kaw lus lossis cov khoom siv los ntawm tus lej ntawm kev ua tsis tiav uas tshwm sim thaum lub sijhawm ntawd. Piv txwv li, yog tias lub kaw lus ua haujlwm rau 1000 teev thiab ntsib peb qhov ua tsis tiav, MTBF yuav yog 1000 teev / 3 tsis ua haujlwm = 333.33 teev.
Vim li cas MTBF tseem ceeb?
MTBF yog ib qho tseem ceeb vim tias nws pab cov koom haum nkag siab txog kev cia siab ntawm lub cev thiab npaj rau kev hloov lossis kho. Qhov no tuaj yeem yog qhov tseem ceeb tshwj xeeb hauv cov txheej txheem tseem ceeb, xws li cov uas txhawb nqa kev lag luam tseem ceeb lossis kev nyab xeeb rau pej xeem, qhov twg qhov tsis ua haujlwm tuaj yeem muaj qhov tshwm sim loj. Los ntawm kev nkag siab txog MTBF rau ib qho kev kaw lus, cov koom haum tuaj yeem tsim cov tswv yim los txo qis qis thiab txhim kho kev ntseeg tau.
Koj tuaj yeem txhim kho MTBF li cas?
Muaj ntau txoj hauv kev uas cov koom haum tuaj yeem txhim kho MTBF:
- Txhim kho kev tiv thaiv: Kev saib xyuas tsis tu ncua tuaj yeem pab txuas ntxiv lub neej ntawm cov kab ke los ntawm kev txheeb xyuas thiab daws cov teeb meem ua ntej lawv tshwm sim.
- Siv cov khoom ua tau zoo: Siv cov khoom ua tau zoo tuaj yeem pab txo qis qhov ua tsis tiav thiab txuas ntxiv lub neej ntawm lub cev.
- Ua raws li qhov kev zov me nyuam cov khoom seem: Muaj cov khoom seem ntawm tes tuaj yeem pab txo qis lub sijhawm los ntawm kev tso cai rau kev kho sai thaum muaj qhov tsis ua tiav.
- Siv cov txheej txheem kev saib xyuas kev kwv yees: Cov thev naus laus zis xws li kev soj ntsuam kev vibration, kuaj ultrasonic, thiab kev ntsuas cua sov tuaj yeem pab txheeb xyuas qhov ua tsis tiav ua ntej lawv tshwm sim, tso cai rau kev kho kom raws sijhawm.
Los ntawm kev siv cov tswv yim no thiab lwm cov tswv yim, cov koom haum tuaj yeem txhim kho MTBF thiab txo qis sijhawm.

MTBF, los yog Lub Sij Hawm Ua Ntej Ua Ntej, yog qhov ntsuas ntawm lub sijhawm nruab nrab ntawm qhov system lossis cov khoom siv tuaj yeem ua haujlwm ua ntej nws ua tsis tiav. Nws yog ib qho kev ntsuas tseem ceeb hauv kev saib xyuas thiab kev ntseeg tau ntawm engineering, vim nws pab cov koom haum nkag siab txog kev cia siab ntawm lub cev thiab npaj rau kev hloov lossis kho. Los ntawm kev siv kev tiv thaiv kev saib xyuas, siv cov khoom zoo, siv cov khoom seem, thiab siv cov txheej txheem kev saib xyuas, cov koom haum tuaj yeem txhim kho MTBF thiab txo qis sijhawm.
