Grate Mechanical Failure
Fault phenomenon:grate daig
Ua rau kev tsom xam
1. Pub ntau dhau ntawm lub grate ua rau lub grate raug crushed:Cov khoom noj ntau dhau ntawm cov grate ntau tshaj nws lub peev xwm thauj khoom, uas yuav ua rau lub grate crushed thiab tsis tuaj yeem ua haujlwm li qub.
2. Lub grate yog daig vim tawg grate:Cov grate tawg tuaj yeem cuam tshuam lub grate, ua rau nws txav tsis tau ib txwm, yog li ua rau lub grate yuav daig.
3. Lub grate tsav txuas pas nrig thiab rocker lub rooj bolts yog tawg los yog deformed, ua rau lub grate yuav daig:Yog hais tias lub grate tsav txuas pas nrig lossis rocker lub rooj bolts tawg los yog deformed, nws yuav ua rau lub grate yuav daig, cuam tshuam rau kev ua haujlwm ntawm cov grate.
4. Qhov sib txawv ntawm cov grate thiab cov phab ntsa muab faib yog me me heev, thiab qhov kub hloov pauv ua rau nthuav dav yuav raug thaiv thiab daig:Yog hais tias qhov sib txawv ntawm cov grate thiab cov phab ntsa muab faib me me dhau lawm, ces thaum huab cua kub hloov pauv, vim thermal expansion, grate expansion yuav raug thaiv, ua rau jamming.
5. Qhov sib txawv ntawm qhov kev taw qhia lub log ntawm ob sab ntawm lub grate khi pas nrig yog me heev, thiab nthuav dav yog thaiv thiab daig:Yog tias qhov sib txawv ntawm qhov kev taw qhia lub log ntawm ob sab ntawm lub grate khi pas nrig tsis txaus, nws tseem yuav ua rau muaj kev cuam tshuam vim qhov cuam tshuam loj thaum qhov kub hloov pauv.
6. Lub grate roller bearing yog ntim nrog plua plav thiab tsis tuaj yeem tig, ua rau lub grate kuj nce thiab jam:Yog tias cov plua plav lossis lwm yam impurities nkag mus rau hauv cov menyuam cov kabmob, nws yuav ua rau cov menyuam tsis tuaj yeem tig ib txwm, yog li ua rau kev khiav haujlwm ntawm cov grate thiab ua rau jamming.
Txoj kev kho:
1. Thaum ua haujlwm, tus neeg teb xov tooj yuav tsum tau tshawb xyuas qhov hluav taws kub ntawm qhov chaw kom tsis txhob muaj cov grate raug crushed los ntawm kev noj ntau dhau.
2. Rau qhov teeb meem ntawm grate tawg, nws yuav tsum tau ua tib zoo xyuas thaum kho. Yog tias muaj cov kab nrib pleb hauv daim ntawv grate, nws yuav tsum tau hloov lub sijhawm. Txhawm rau txheeb xyuas daim ntawv grate, lub grate yuav tsum tau kuaj ib zaug thaum nws nyob hauv qhov chaw thiab ib zaug thaum nws tawm ntawm qhov chaw. Thaum lub sij hawm soj ntsuam, nws yuav tsum tau xyuas ntawm lub grate thiab nyob rau hauv lub cua chamber tib lub sij hawm. Thaum lub sijhawm ua haujlwm, tswj lub qhov cub kub ntawm ib qho channel kom zoo, thiab nws yog qhov zoo tshaj plaws los tswj qhov nruab nrab qhov cub kub ntawm ib ncig ntawm 950 degree. Lub cub tawg tsis yooj yim rau coke, txo qhov kev pheej hmoo ntawm coke ntog thiab tawg lub grate.
3. Thaum lub qhov cub kaw lawm, nrhiav ib txoj hauv kev los txuas cov hlua khi rau qhov chaw ntawm cov hlua khi hlua khi uas muaj kev cuam tshuam los tiv thaiv nws ntawm kev tawg thaum lub sijhawm ua haujlwm.
4. Thaum lub qhov cub raug kaw rau kev saib xyuas, kev teeb tsa ntawm lub grate tsav system yuav tsum tau ua nruj me ntsis raws li cov kev cai. Tus kws tshaj lij ntawm boiler yuav tsum nco ntsoov qhov kev txhim kho ntawm qhov chaw thiab kev saib xyuas thiab kev qhia tshwj xeeb. Lub installation clearance thiab hnav ntawm lub grate tsav phau ntawv qhia log, hnav ntawm cov menyuam thiab hnav-resistant phaj, txawm tias cov menyuam rotates flexibly, kev sib cuag ntawm cov menyuam thiab cov hnav-resistant phaj, thiab seb cov grate clearance ua tau raws li qhov yuav tsum tau muaj. yuav tsum tau kuaj xyuas thiab paub tseeb ntawm tus kheej. Kev saib xyuas yog nruj me ntsis ua raws li peb theem kev lees paub zoo kom txo qis kev ua haujlwm tsis zoo thaum lub sijhawm ua haujlwm thiab ua kom lub cev ua haujlwm ntawm cov khoom siv.
