Thaum tav su ntawm Lub Ib Hlis 31, 2000, MD-83 lub dav hlau tau tawm ntawm Puerto Vallarta International Tshav Dav Hlau hauv Mexico. Thaum lub sij hawm caij nkoj, kab rov tav stabilizer malfunctioned, ua rau lub aircraft rau lub qhov ntswg-down thiab yuam nws mus plunge sai. Lub dav hlau thaum kawg tau poob rau hauv dej hiav txwv Pacific, 4.3 km sab qaum teb ntawm Annacapa Island, California. Tag nrho ob tus neeg tsav dav hlau, peb tus neeg caij dav hlau, thiab 83 tus neeg caij tsheb (suav nrog peb tus menyuam) ntawm lub nkoj tuag.
Kev soj ntsuam ntawm lub dav hlau rov qab los wreckage qhia cov hauv qab no:
• Kwv yees li 90% ntawm cov xov ntawm cov txiv ntoo saum toj kawg nkaus tau hnav, thaum kawg ua rau tag nrho cov txiv ntoo kom tshem tawm tag nrho.
• Cov bolts rov qabtsis muaj lubrication, nrog tsis muaj roj residue pom.
Kev tshuaj xyuas pom tau tias kwv yees li 90% ntawm cov txiv ntoo 'cov xov tau hnav, thiab tag nrho cov txiv ntoo tau tshem tawm tag nrho thaum lub caij sib tsoo. Cov kab rov tav stabilizer tau ua tsis zoo los ntawm cov cua ntws. Tsis tas li ntawd, NTSB pom tias qhov hnav tus nqi ntawm cov txiv ntseej threads tau siab dua qhov nruab nrab. The NTSB finalized thatqhov tsis muaj roj nplua nyeem thiab qhov ua rau hnyav hnyav ntawm cov txiv ntoo yog qhov ua rau muaj kev sib tsoo.
Raws li kev txheeb cais los ntawm US Department of Energy,lubrication tsis zoosuav txog li 40% ntawm cov kabmob tsis ua haujlwm, nce nqi kho los ntawm 2-3 zaug. Lub hauv paus ua rau feem ntau yooj yim. Piv txwv li, nyob rau hauv lub tsheb ciav hlau freight derailment, kev tshawb fawb tau qhia tias ib tug overheated bearing nyob rau hauv lub qag lub thawv ua rau lub qag tawg, ua rau lub tsheb ciav hlau overturned, tsheb thauj mus los cuam tshuam rau ob peb teev, thiab kev puas tsuaj loj heev. Bearing Failure Damage Root Cause Analysis: Bearings yog cov khoom tseem ceeb ntawm cov khoom siv feem ntau. Thaum cov kabmob tsis ua haujlwm, cov khoom siv nres. Nrhiav lub hauv paus ua rau kom tsis txhob rov tshwm sim yog qhov tseem ceeb. Qhov tseeb, ib zaug cov kabmob puas lawm, nws maj mam deteriorates kom txog thaum nws yuav siv tsis tau; los ntawm thaum ntawd, tag nrho cov pov thawj ntawm kev ua tsis tiav yuav raug rhuav tshem.
Daim ntawv tshaj tawm World Bank qhia tias kev siv hluav taws xob pov tseg vim muaj teeb meem lubrication suav txog 3% -5% ntawm tag nrho cov kev siv hluav taws xob hauv kev lag luam thoob ntiaj teb, sib npaug li qhov poob ntawm kwv yees li 120 lab tons ntawm cov qauv thee sib npaug txhua xyoo. Cov koom haum tso cai thoob ntiaj teb kwv yees tias 30% -50% ntawm kev siv hluav taws xob thoob ntiaj teb yog vim kev sib txhuam thiab hnav, nrog raulubrication tsis zoo ua rau ntau tshaj 60% ntawm cov khoom siv. Tsis tas li ntawd, ntau dua 50% ntawm cov cuab yeej siv kho mob hnyav tshwm sim los ntawm kev hnav ntau dhau loslos ntawm lubrication tsis ua hauj lwm. Kev siv cov thev naus laus zis lubrication tuaj yeem txo qhov kev sib txhuam thiab hnav, txo qhov tshwm sim ntawm cov khoom siv sib tsoo hnyav, yog li ua tiav kev txuag hluav taws xob ncaj qha, tsim kom muaj txiaj ntsig rau tag nrho cov kev sib txuas hauv kev lag luam, thiab kev txhim kho kev lag luam.
Qhov teeb meem ntawm lubrication system tsis ua hauj lwmyog ib qho tseem ceeb hauv kev lag luam tam sim no, thiab tau dhau los ua qhov tseem ceeb ntawm kev txwv cov cuab yeej kev ntseeg siab thiab kev tsim khoom. Cov ntaub ntawv los ntawm Lub Koom Haum Ntiaj Teb Kev Ua Haujlwm (ILO) qhia tau hais tias kev sib tsoo tshuab los ntawm lubrication tsis ua haujlwm suav txog 22% ntawm kev nyab xeeb kev lag luam, thiab tuaj yeem yooj yim ua rau siab - kub kub lossis cov khoom tawg.
Yog li ntawd, xaivtxoj cai lubrication system rau koj cov khoom sivyog qhov tseem ceeb.Centralized roj lubrication systemyog ib txoj hauv kev uas siv cov txheej txheem tshwj xeeb los muab cov roj lubricating lossis roj rau tag nrho cov ntsiab lus lubrication ntawm cov khoom siv. Cov txheej txheem no feem ntau muaj cov twj tso kua mis lubrication, reservoir, distributor, pipelines, thiab tswj cov khoom siv. Nws tuaj yeem tau txais thiab meej muab cov roj nplua nyeem rau ntau lub ntsiab lus lubrication raws sijhawm thiab ntau npaum li cas raws li cov khoom siv kev ua haujlwm thiab lubrication xav tau, ua tiavnws pib lubrication, npaum thiab txhim khu kev qha lubrication.
Lub ntsiab zoo ntawm acentralized roj lubrication system:
Automated tswj: Sijhawm thiab ntsuas lubrication txo qis kev ua haujlwm thiab txhim kho qhov tseeb piv rau phau ntawv lubrication.
Multi-point synchronous lubrication: Centralized lubrication txhim kho cov cuab yeej siv tau zoo.
Kev soj ntsuam ntse: tiag tiag- lub sijhawm saib xyuas muab kev ceeb toom ntxov ntawm lubrication anomalies, txhim kho cov lus teb ceev.
Txo cov nqi tu: Txo tag nrho cov nqi ntawm cov tswv cuab (CCO) thiab txuas cov cuab yeej siv lub neej.
Centralized roj lubricationmuaj qhov zoo tshaj plaws ntawm kev siv phau ntawv lubrication. Nws tuaj yeem tswj xyuas cov roj kom raug, ua tiav cov roj sib xyaw thiab lub sijhawm roj rau ntau lub ntsiab lus lubrication, thiab xyuas kom meej cov nyhuv lubrication; Los ntawm kev ua haujlwm tsis siv neeg, nws txuag lub zog thiab lub sijhawm, thiab txo qis sijhawm; Nws tseem tuaj yeem saib xyuas qhov tsis raug ntawm lub sijhawm tiag tiag thiab muab kev ceeb toom ntxov; Nws txo qhov tshwm sim ntawm cov neeg ua haujlwm raug cuam tshuam thiab muaj kev nyab xeeb dua hauv qhov chaw tshwj xeeb; Nws kuj txo cov roj lubricating pov tseg thiab cov pa phem, txuag lub zog thiab kev tiv thaiv ib puag ncig.
