Peb Qhov Tseem Ceeb Ua Ntej -Kev Ua Haujlwm Kev Tshawb Fawb Txog Slurry Pumps: Tiv thaiv lub cev muaj zog Burnout Thiab cov yeeb nkab thaiv
Peb feem ntau tau txais kev pabcuam xwm txheej ceev ceev. Cov neeg ua haujlwm tshaj tawm xov xwm lub cev muaj zog haus luam yeeb tam sim tom qab lub zog- nce, lossis cov twj tso kua mis tuav tag nrho tsuas yog ob feeb ua haujlwm. Lub tsev twj tso kua mis tau scorching kub, kub dhau mus kov yam xyuam xim. Thaum disassembly, peb tsis tshua pom muaj qhov tsis xws luag hauv cov khoom lawv tus kheej; Hauv feem ntau ntawm cov xwm txheej, qhov teeb meem tshwm sim los ntawm kev saib xyuas qee qhov me me - tseem ceeb heev - cov ntsiab lus ua ntej ua haujlwm. Feem ntau qhov ua tsis tiav tsuas yog vim cov neeg ua haujlwm hla qhov tseem ceeb tseem ceeb ua ntej - pib kuaj xyuas.
Slurry twj tso kua mis yog ua kom tawv los tuav hnyav hnyav ntawm cov xuab zeb, gravel thiab silt sib tov. Txawm li cas los xij, kev saib xyuas tsis tu ncua ua ntej tig lub tshuab ua kom yooj yim ua rau muaj kev puas tsuaj. Hauv qab no yog peb qhov yuav tsum tau- ua ntej- kev tshuaj xyuas kev ua haujlwm. Ntau tus neeg ua haujlwm tsis quav ntsej cov txheej txheem niaj hnub no txhua xyoo, tab sis lawv muaj txiaj ntsig tiv thaiv lub cev kub hnyiab thiab cov teeb meem ntawm cov kav dej.
Ua ntej tshaj, xyuas tag nrho cov tshuab hluav taws xob. Kev tsim kho qhov chaw siv hluav taws xob sib txawv heev, los ntawm cov tshuab hluav taws xob nqa tau mus rau kev teeb tsa hluav taws xob ib ntus, uas feem ntau ua rau muaj qhov hloov pauv tsis ruaj khov. Cov kab hluav taws xob feem ntau nyob rau ntawm qhov chaw ntxhib, yooj yim rau kev raug tsoo los ntawm kev sib tsoo los yog txiav los ntawm cov pob zeb ntse. Cov kab hluav taws xob sab nraud uas ua rau cov av nkos thiab dej tam sim ntawd ua rau luv luv thiab hluav taws xob hluav taws xob ib zaug, ua rau kom tsis txhob muaj lub cev muaj zog.
Taug kev tag nrho cov kab ntev los xyuas cov pob qij txha tsis muaj dej tsis zoo thiab hnav cov rwb thaiv tsev uas nthuav tawm cov xov tooj hlau sab hauv. Daim tshev ceev no tsuas siv sijhawm ib feeb thiab them nyiaj ntau heev. Siv lub megohmmeter los ntsuas lub cev muaj zog tiv thaiv kev tiv thaiv. Tus nqi qis dua 0.5 megohms xav tau kom qhuav; yuam kev pib hauv lub xeev no hlawv tawm stator coils sai sai. Kuj rov kho txhua qhov txuas txuas, tshwj xeeb tshaj yog peb -theem fais fab txuas. Lub zog uas ploj lawm ua rau lub cev muaj zog tsis muaj kiv, spikes hluav taws xob tam sim no thiab tsim kom pom tseeb hlawv tsw. Kev teeb tsa hluav taws xob tsis ruaj khov ua rau cov twj tso kua mis ua rau tsis ua haujlwm sai.
Thib ob, tshem tawm tag nrho cov kav dej zais cia. Clogs tsis tshua muaj nyob rau hauv lub twj tso kua mis lub cev nws tus kheej, thiab feem ntau obstructions nyob rau hauv cov dej ntws thiab downstream kav. Suction sab ko taw valve strainers yooj yim cuab twigs, rags thiab yas pov tseg. Blocked strainers txiav lub zog nqus, tsim lub tshuab nqus tsev siab hauv lub twj tso kua mis thiab ua rau muaj kev vibration hnyav. Mechanical seals hnav ua ntej nyob rau hauv xws li strain, ua raws li lub cev muaj zog load thiab ntse kub nce.
Siv ob feeb tshem tawm cov khib nyiab pov tseg yuav txuag tau ntau lub sijhawm thiab tus nqi siv rau tag nrho cov twj tso kua mis disassembly thiab kho. Cov khoom seem slurry hardens rau hauv cov khoom chunks hauv cov twj tso kua mis tsis pub dhau ob peb teev, xauv impellers ruaj khov rau hauv qhov chaw. Khiav ib tug seized impeller tso siab heev sib npaug rau thawb tawm tsam pob zeb. Qhib cov chaw nres nkoj ntws thiab siv cov ntsia hlau ntev los xyuas qhov kev txav ntawm lub impeller, tshem tawm tag nrho cov khib nyiab qhuav kom huv si.
Txhua lub pob li qub thiab cov raj xa dej yuav tsum tau qhib tag nrho ua ntej pib. Qee tus neeg ua haujlwm ib nrab kaw li qub ntshai tsam cov kua dej surges, uas tsuas yog cov kua hauv lub twj tso kua mis xwb. Circulating kua heats sai thiab vaporizes, tsim hluav taws xob overloads burns tawm motors nyob rau hauv vib nas this. Manually sim viav vias kos li qub los txiav txim tawm txoj haujlwm kaw. Thaiv qhov hluav taws xob tsim hluav taws xob rauj quab yuam uas rhuav tshem tag nrho cov kav dej. Unobstructed piping cia cov twj tso kua mis ua haujlwm ntawm kev tsim ua haujlwm.
Thib peb, cia siab rau lub cev kov kom tig lub twj tso kua mis thiab xyuas cov txheej txheem lubrication. Fine sediment settles nruj nreem nruab nrab ntawm shafts thiab impellers tom qab kaw, tsis pom qhov pom kev pom. Siv cov cuab yeej tshwj xeeb los tig lub ncej clockwise ob peb zaug. Kev sib hloov du, ruaj khov uas tsis muaj kev sib tsoo lossis jamming teeb liab muaj kev nyab xeeb pib ua haujlwm. Tsau, unturnable shafts yuav luag ib txwm txhais tau tias sediment seizing sab hauv; powering nyob rau hauv cov mob no ncaj qha rhuav tshem motors.
Tshawb xyuas cov kab noj hniav roj rau emulsified discoloration, thickening lossis dryness. Khiav bearings yam tsis muaj lubrication zoo overheats sai, xauv thiab txawm twists lub cev muaj zog ncej nyob rau hauv siab - khiav ceev. Cov cuab yeej haum nrog cov tshuab foob thiab cov tshuab dej foob yuav tsum tau muab dej qhib ua ntej pib ua haujlwm. Qhuav seals nto tawg yooj yim, cia slurry ntws ncaj qha mus rau hauv lub cev muaj zog interiors thiab ua rau zais burnout. Roj refills thiab kaw dej hloov kho tsuas yog siv sijhawm li 3 mus rau 5 feeb, ua kom cov cuab yeej siv tau zoo heev.
Hauv cov ntsiab lus, cov kev kuaj xyuas siv tau tsuas yog siv tsib feeb tag nrho: paub meej tias lub zog ruaj khov, tshem tawm tag nrho cov kev cuam tshuam cov kav dej thiab tshawb xyuas qhov hloov pauv hloov tau. Ua raws li cov kev coj noj coj ua niaj hnub no ua rau hnyav- lub luag haujlwm slurry twj tso kua mis khiav tsis tu ncua thaum ua haujlwm hnyav av nkos, xa cov kev ua tau zoo sib xws rau kev siv sijhawm ntev -.
