Feeder Failure

Fault phenomenon: Lub feeder yog daig thiab tsis tuaj yeem txav mus rau pem hauv ntej lossis rov qab

Ua rau Analysis:

1. Lub feeder nce mus dhau qhov kev txwv thiab tsis tuaj yeem thim rov qab:Thaum lub feeder nce mus dhau qhov kev txwv, lub tsheb khib nyiab yuav poob thiab tuav lub feeder, tiv thaiv nws los ntawm kev thim rov qab. Qhov no feem ntau tshwm sim thaum ob lub laub feeder tsis khiav synchronously.

2. Lub feeder zawv zawg platform casting yog tawg los yog warped, ua rau feeder yuav daig:Yog hais tias lub hauv ntej thiab nram qab castings ntawm feeder zawv zawg platform yog tawg los yog warped, nws yuav ua rau lub feeder tsuas yog ua kom tiav ib nrab ntawm cov hlab ntsha, uas yog ib tug kuj yooj yim teeb meem los txheeb xyuas.

3. Lub partition phab ntsa castings ntawm ob sab ntawm lub feeder yog tawg los yog xoob:Nyob ntawm qhov chaw tshwj xeeb ntawm kev faib phab ntsa casting xoob, lub feeder yuav daig ntawm ib qho chaw tshwj xeeb. Hauv qhov no, qhov kev ncaj ncees thiab kev txhim kho ntawm qhov muab faib phab ntsa casting yuav tsum tau kuaj xyuas.

4. Kev kho tsis raug ntawm qhov sib txawv ntawm lub feeder thiab phab ntsa muab faib tom qab kev kho: Thaum lub sij hawm txij nkawm, yog tias qhov sib txawv ntawm lub feeder thiab cov phab ntsa muab faib rau ntawm ob sab tsis raug kho kom raug, qhov sib txawv yuav tsawg dhau. Thaum lub sijhawm ua haujlwm, yog tias cov khib nyiab hlawv ntawm lub laub feeder, lub feeder yuav daig los ntawm phab ntsa muab faib vim thermal expansion thiab tsis tuaj yeem txav mus rau pem hauv ntej lossis rov qab.

5. Lub trolley tau daig vim muaj cov dej khib nyiab ntau dhau ntawm cov khib nyiab:Thaum muaj cov av ntau hauv cov khib nyiab, tshwj xeeb tshaj yog thaum tuav cov khib nyiab pov tseg, ntau cov khib nyiab tuaj yeem nkag mus rau qhov sib txawv ntawm cov khoom noj khoom haus thiab cov phab ntsa. Raws li cov sediment accumulates, lub feeder yuav daig.

Txoj kev kho:

Kauj ruam 1:Kho lub thoob khib nyiab baffle los daws qhov teeb meem ntawm feeder rov qab obstruction

Ua ntej, khiav lub feeder kom nws txav mus rau pem hauv ntej thiab tso cov thoob khib nyiab baffle. Tom qab ntawd, nqa lub baffle upward kom paub tseeb tias nws tsis thaiv lub feeder txoj kev rov qab.

Kauj ruam 2:Deal nrog cov teeb meem ntawm feeder hauv qab phaj lifting

Raws li kev daws teeb meem ib ntus, cov strokes ntawm ob lub feeder trolleys ntawm lwm lub feeder tuaj yeem hloov kho kom zoo ib yam kom cov kev tswj xyuas ua ntu zus tuaj yeem ua tau zoo, uas tsis tshua muaj kev cuam tshuam rau kev ua haujlwm tag nrho.

Kauj Ruam 3:Deal nrog feeder partition phab ntsa teeb meem

Feeder partition phab ntsa teeb meem feem ntau tsis daws thaum lub sijhawm ua haujlwm. Yog tias txoj haujlwm jamming tsis zoo, nws yuav ua rau txo qis hauv cov hlab ntsha ntawm lub feeder trolley, yog li cuam tshuam rau kev ua haujlwm. Nyob rau hauv cov ntaub ntawv no, manually cuam tshuam nyob rau hauv pub mis yuav tsum tau. Yuav kom daws tau qhov teeb meem no tag nrho, nws yog ib qho tsim nyog yuav tsum tau nres qhov cub rau kev ua haujlwm.

Kauj Ruam 4:daws qhov teeb meem ntawm feeder jamming tshwm sim los ntawm kev hloov kub

Rau jamming tshwm sim los ntawm qhov kub thiab txias hloov uas ua rau qhov sib txawv ntawm lub feeder thiab partition phab ntsa ntawm ob sab me me, qhov kub ntawm lub feeder platform yuav txo tau los ntawm kev kho cov txheej txheem combustion. Feem ntau, qhov no tuaj yeem kho lub feeder kom ua haujlwm li qub.

Kauj Ruam 5:Teeb meem nrog cov teeb meem ntawm lub laub feeder raug daig vim muaj cov ntsiab lus sediment hauv cov khib nyiab

Thaum lub laub feeder daig vim muaj cov ntsiab lus ntawm cov khib nyiab siab, koj tuaj yeem tso tseg ib ntus tso cov khib nyiab rau hauv qhov chaw pov tseg lossis cov khib nyiab stale. Nyob rau tib lub sijhawm, tsim nyog nce cov roj feeder siab (nyob rau hauv ib txwm muaj, lub feeder laub roj siab yog teem rau 12MPa), kom lub feeder tuaj yeem maj mam rov ua haujlwm li qub.
