Raws li "kev nyab xeeb lub plawv" ntawm cov tshuab hnyav, cov tshuab conveyor, thiab lwm yam khoom siv, kev lag luam ruaj khov ntawm kev lag luam nres yog ncaj qha ntsig txog kev ruaj ntseg thiab kev ua haujlwm. Txawm li cas los xij, nyob rau hauv ntev - lub sijhawm ua haujlwm siab load, peb hom kev ua txhaum xws li cua sov, suab nrov txawv txav, thiab nres tsis ua haujlwm feem ntau tshwm sim, uas tsis tsuas yog cuam tshuam rau kev tsim khoom tab sis kuj yuav ua rau muaj kev nyab xeeb. Niaj hnub no, raws li kev paub dhau los ntawm 20 xyoo ntawm kev tshawb fawb nres thiab tom qab- kev muag khoom, peb yuav rhuav tshem lub hauv paus ua rau lub cev tsis ua haujlwm thiab muab 3-feeb kev daws teeb meem los pab koj sai sai rov qab ua haujlwm zoo ntawm cov khoom siv.
Ib. Peb qhov loj loj - zaus faults: nrhiav lub hauv paus los ntawm qhov tshwm sim.
Tom qab qhov tshwm sim ntawm qhov tsis sib txawv, feem ntau pom tseeb ntawm qhov teeb meem, thiab kev txheeb xyuas qhov tseeb ntawm qhov tshwm sim yog thawj kauj ruam hauv kev daws teeb meem zoo.
1. Fault 1: Cov cua kub tsis zoo ntawm tus nres.
- Cov xwm txheej tseem ceeb: Tom qab nres lub tshuab, kov lub nres caliper / nres khau cheeb tsam, qhov kub siab tshaj 60℃(ib txwm ua haujlwm kub feem ntau yog qis dua 45 degree), thiab qee qhov xwm txheej tau nrog cov ntxhiab tsw tsw qab.
- Feem ntau cov hauv paus ntsiab lus: kev tshem tawm me me dhau lawm, thiab cov khau khiab nres thiab lub log nres yog nyob rau hauv ib lub xeev haum rau lub sijhawm ntev; Lub tshav kub dissipation channel yog thaiv los ntawm cov roj thiab hmoov av, thiab cov cua kub tsis tuaj yeem dissipated raws sijhawm; Cov kabmob hnav ua rau muaj kev tiv thaiv kev sib hloov, tsis ncaj qha ua rau kub nce.
- Kev daws teeb meem:
- Kho tus nres tshem tawm mus rau tus qauv ntau yam (feem ntau yog 0.5-1mm), thiab ntsuas qhov kev ncua deb ntawm tus brake khau thiab lub log nres los ntawm kev kho lub ntsia liaj qhov rooj.
-Tshuaj cov roj thiab hmoov av nyob rau hauv cov cua kub dissipation channel nrog lub siab - rab phom cua siab. Yog tias cov khau khau khiab muaj roj, hloov lawv nrog cov tshiab thiab tshawb xyuas cov roj to.
-Kuaj xyuas qhov hnav ntawm cov kabmob. Yog tias muaj qhov xoob lossis lub suab nrov txawv txav, tam sim ntawd hloov cov kabmob qub ntawm tib tus qauv kom tsis txhob muaj kev puas tsuaj ntxiv. - Ceeb Toom: Tom qab hloov cov kabmob, cov khoom siv yuav tsum nyob twj ywm rau 10 feeb kom paub meej tias tsis muaj qhov kub thiab txias nce ua ntej khiav nrog load.
2. Fault 2: Cov suab nrov txawv txav thaum ua haujlwm
- Cov xwm txheej tseem ceeb: Thaum lub nres qhib thiab kaw, muaj "ntsuas qw", "hlau sib txhuam suab" lossis "lub suab nrov", thiab qhov zaus ntawm lub suab sib txawv nrog kev khiav hauj lwm ceev ntawm cov khoom siv.
- Feem ntau cov hauv paus ntsiab lus: Nres khau hnav mus rau qhov txwv (kev sib txhuam cov khoom tuab tsawg dua 3 hli), thiab cov hlau substrate ncaj qha hu rau lub log nres; Kos, grooves, los yog xeb tshwm nyob rau saum npoo ntawm lub log nres, ua rau qhov sib txhuam tsis sib xws; Cov khoom sib txuas xoob (xws li bolts thiab springs) tuaj yeem ua rau muaj kev sib tsoo thaum lub sijhawm braking.
- Kev daws teeb meem:
-Hloov cov khau nres nrog hnav ntau dhau thiab xaiv cov khoom siv sib txhuam qub uas haum rau cov qauv khoom siv kom ntseeg tau tias kev ua haujlwm ruaj khov.
-Tau qhov khawb ntawm qhov chaw ntawm lub log nrog cov ntawv xuab zeb zoo. Yog hais tias cov xeb yog qhov hnyav lossis qhov tob tob tshwm sim, lub log nres yuav tsum tau kho los ntawm kev tig los yog hloov ncaj qha.
-Siv tus ciaj ntswj txhawm rau txhawm rau txhawm rau txuas cov bolts thiab cov ntsaws ruaj ruaj ib qho los ntawm ib qho, kom ntseeg tau tias tag nrho cov khoom tsis xoob, thiab hloov cov khoom caij nplooj ntoos hlav laus yog tias tsim nyog. - Ceeb Toom: Tom qab hloov cov khau nres, nws yuav tsum tau ua 3-5 tsis muaj kev sib tsoo braking kom paub meej tias cov suab nrov txawv txav tau raug tshem tawm ua ntej siv nrog kev thauj khoom.
3. Fault 3: Nres nres (qhov txhaum loj tshaj plaws)
- Cov xwm txheej tseem ceeb: Tom qab taug kev ntawm tus brake pedal / ua rau lub nres nres, cov khoom siv qeeb qeeb, tsis tuaj yeem nres tsis tu ncua, lossis ntsib qhov tshwm sim "dov" tom qab braking.
- Feem ntau cov hauv paus ntsiab lus: tsis txaus siab nyob rau hauv hydraulic / pneumatic systems (xws li roj kav dej, cua twj tso kua mis tsis ua hauj lwm); Kev hnav hnyav lossis tshem tawm ntawm nkawm khau nres, ua rau poob ntawm kev sib txhuam braking peev xwm; Electromagnetic / lub cev muaj zog ua haujlwm tsis zoo, tsis tuaj yeem tsav lub tshuab nres kom kaw ib txwm.
- Kev daws teeb meem:
-Kuaj xyuas cov kav dej hydraulic / pneumatic, hloov cov kav dej xau los yog cov ntsaws ruaj ruaj, thiab pib lub twj tso kua mis los ntxiv qhov siab rau tus qauv (0.8-1.2MPa).
-Tam sim ntawd hloov cov khau khiab nres uas tau poob los yog hnav hnyav, thiab xyuas kom haum zoo thaum lub sij hawm teeb tsa kom tsis txhob cuam tshuam qhov cuam tshuam ntawm kev sib tsoo vim qhov sib txawv ntawm kev teeb tsa.
-Kuaj xyuas cov khoom siv hluav taws xob thiab xaim ntawm electromagnet/motor. Yog hais tias lub coil burns tawm los yog lub cev muaj zog malfunction, hloov nws nrog thawj qhov chaw ntawm tib yam specifications thiab ua ib tug tsis muaj - load test tom qab hloov. - Ceeb Toom: Tom qab qhov kev ua txhaum ntawm lub nres nres tau raug daws lawm, kev ntsuas kev thauj khoom (nrog rau kev thauj khoom ntawm 50% -80% ntawm cov khoom ntsuas) yuav tsum tau ua kom paub tseeb tias qhov kev ua haujlwm ntawm lub braking ua tau raws li tus qauv ua ntej rov ua haujlwm li qub.
