Cov Kev daws teeb meem rau cov hlau cog
Cov Txheej Txheem Hlau Cog thiab Daim Ntawv Thov Phaj Hnav
Hauv cov lag luam hnyav xws li kev tsim hlau, kev hnav thiab xeb yog cov ua rau cov khoom siv tsis ua haujlwm, suav txog ze li ntawm 80% ntawm tag nrho cov kev puas tsuaj. Thoob ntiaj teb, cov kev poob no siv li 4% ntawm GDP thoob ntiaj teb thiab txog li 30% ntawm cov hlau tsim tawm txhua xyoo. Hauv Suav teb, qhov kev poob ntsig txog kev hnav ib leeg yog 3-5 RMB ib tuj ntawm cov hlau tsim tawm, uas qhia txog ob qho tib si tus nqi loj thiab lub sijhawm tseem ceeb rau cov ntaub ntawv hnav.
Thaum cov chaw tsim hlau ntsib kev raug mob, kev cuam tshuam, thiab cua sov tas li, qhov xav tau cov kev daws teeb meem hnav ruaj khov yeej tsis tau muaj ntau dua li no. Wodon muab cov phaj hlau tiv taus hnav uas tsim los rau cov khoom tseem ceeb, xws li hoppers, chutes, bins, thiab screen plates—pab cov chaw tsim hlau kom txo qhov poob, ntev lub neej ntawm cov khoom siv, thiab txhim kho kev ua haujlwm zoo.

Vim li cas lub grate bar thiaj li puas tsuaj heev?
1. Qhov chaw kub siab sintering
• Lub xeev kub siab ntev ua rau cov khoom siv grate bar mos, thermal qaug zog thiab oxidation tev tawm.
• Kev hloov pauv ntawm kev nthuav dav thiab kev sib cog lus ntawm cua sov ntau zaus yuav ua rau muaj kev tawg ntawm cua sov thiab kev tev tawv ntawm cov qauv.
2. Muaj zog khawb thiab hnav cov khoom me me
• Cov khoom siv raw sintering muaj cov khoom me me uas muaj zog heev xws li hmoov hlau, hmoov coke, thiab limestone. Cov no ua rau saum npoo ntawm lub grate bar kub ceev thaum lub sijhawm sintering, ua rau muaj kev puas tsuaj loj heev.
•Tshwj xeeb tshaj yog thaum cov khoom poob, tso, thiab tig, qhov cuam tshuam ntawm cov khoom me me muaj zog dua.
3. Cov khoom siv cuam tshuam ntau zaus
•Thaum lub sijhawm ua haujlwm, cov pob zeb sintered raug sib sau ua ke, co, thiab tshem tawm tas li. Lub phaj grate raug kev cuam tshuam hnyav, ua rau muaj kev puas tsuaj rau lub zog.
•Qee lub chaw ua hlau siv cov khoom siv vibrating unloading, uas kuj tseem yuav ua rau qhov hnav thiab tawg los ntawm kev cuam tshuam tshuab hnyav dua.
Cov Cheeb Tsam Tseem Ceeb Uas Ua Rau Cov Cua Sov Hlau Uas Yuav Hnov Ntau
Cov kiv cua hlau ua haujlwm nyob rau hauv qhov kub thiab txias, plua plav ntau, thiab kev thauj khoom ntau. Raws sijhawm, ntau yam khoom siv yuav raug kev puas tsuaj loj heev, tshwj xeeb tshaj yog:
1. Lub kiv cua Impeller (Hniav & Hubs)
•Ua rau hnav: Kev cuam tshuam thiab kev hloov pauv tas li los ntawm cov khoom kub xws li hmoov av sinter, cov hlau ore me me, thiab hmoov thee.
•Hom kev hnav: Kev hnav tsis zoo, kev yaig, kev oxidation ntawm qhov kub siab.
• Qhov teeb meem ib txwm muaj: Cov hniav nyias nyias, tawg, thiab tsis sib npaug vim yog poob ntau heev.
2. Cov Khoom Siv Sab Hauv / Vaj Tse
•Ua rau hnav: Cov cua ntsawj ceev ceev uas nqa cov khoom ntse ntse mus rau sab hauv phab ntsa.
•Hom hnav: Kev hnav uas ua rau xeb thiab sib txhuam, tshwj xeeb tshaj yog ntawm cov khoov thiab thaj chaw nkag.
•Teeb meem ib txwm muaj: Cov ntaub thaiv sab hauv tsev tawg, qhov tho qhov hauv zos, lossis phab ntsa nyias.
3. Cov Vanes Qhia thiab Cov Deflectors Nkag Mus
•Ua rau hnav: Kev nrawm ntawm cov cua uas muaj hmoov av sib xyaw.
•Hom kev hnav: Kev hnav cuam tshuam ntawm cov ces kaum ruaj khov.
•Teeb meem ib txwm muaj: Muaj qhov tawg lossis tawg ua ntej.
Kev daws teeb meem hardfacing rau kev tiv thaiv hnav
Wodon muab cov kev daws teeb meem hardfacing txhim khu kev qha sivCov phaj chromium carbide overlay (CCO)thiabhlau flux core, tsim tshwj xeeb rau cov xwm txheej kev pabcuam hnyav.
Cov txiaj ntsig ntawm kev kho Hardfacing
• Lub neej ntawm lub impeller nce ntxiv 2–5 zaug nrog CCO hardfacing.
• Kev kho kom tawv ntawm qhov chaw ua rau muaj kev hloov pauv sai, txo qis kev kaw khoom kim heev.
• Kev tsim cov nto rov qab kho qhov loj li qub, txhim kho kev ntws ntawm huab cua thiab txo kev co.
