1. Lub hom phiaj ntawm cov khoom siv
Inverted umbrella aerator yog ib qho tseem ceeb ntawm cov khoom siv hauv kev kho dej khib nyiab biochemical.
Lub tshuab feem ntau yog siv rau kev kho dej khib nyiab hauv kev lag luam xws li roj av, tshuaj, tawv, ntawv, tshuaj tua kab, roj, thiab thee.
Nws kuj yog tsim nyog rau kev kho mob ntawm cov dej phwj hauv nroog.
Hauv aeration tso tsheb hlau luam siv cov txheej txheem activated sludge, nws oxygenates thiab sib tov cov cawv kom nthuav tawm cov kab mob aerobic, yog li ua tiav cov dej khib nyiab sai thiab muaj txiaj ntsig.
2. Core Structure & Nta
Lub aerator nta ntau yam qauv tsim los txhim kho kev ua haujlwm zoo.
- Cov khoom xyaw:Lub tshuab muaj lub cev muaj zog, sib txuas, reducer, lubrication system, lifting platform, inverted kaus puag, thiab impeller.
- Inverted Umbrella Impeller:Nws muaj lub zog ua haujlwm siab, thaj chaw sib xyaw dav, tiv thaiv kev txhaws, thiab tuaj yeem tig ob sab pem hauv ntej thiab rov qab.
- Tshwj xeeb Reducer:Nws siv peb lub-theem helical iav reducer uas muaj kev sib kis tau zoo, tsis muaj suab nrov, thiab lub neej ntev.
- Flexible Adjustment:Lub impeller lifting ntaus ntawv tso cai rau kev hloov pauv ntawm qhov tob tob kom tswj tau cov pa oxygenation raws li cov txheej txheem xav tau.
- Tswj ceev:Cov cuab yeej siv qhov sib txawv - zaus tsav (VFD) tswj txee los kho lub cev muaj zog ceev.
3. Txoj Cai Ua Haujlwm & Oxygenation Mechanism
Submerged nyob rau hauv dej nto, lub impeller oxygenates thiab sib tov cov sludge los ntawm peb yam nram qab no:
- Surface Renewal:Cov tshuaj tsuag thiab nqus dej ntawm lub impeller ua rau cov dej khib nyiab tuaj yeem nce thiab nqis nrawm, ua rau cov pa oxygen- tsis muaj dej khib nyiab rau saum huab cua kom siab - nrawm nrawm nrawm.
- Hydraulic dhia:Lub impeller cuam tshuam cov dej tawm sab nraud hauv qhov qis - cov qauv kev sib tw, tsim kom muaj kev dhia hydraulic uas sib xyaw nrog huab cua rau oxygenation.
- Negative Pressure Suction:Raws li lub impeller rotates, ib qho qis - qhov chaw siab ua rau tom qab cov hniav, kos rau hauv huab cua rau oxygenation.
4. Kev Txhim Kho & Kho Cov Lus Qhia
Kev txhim kho kom zoo yog qhov yuav tsum tau ua ua ntej rau kev ua haujlwm ruaj khov.
- Foundation Leveling:Qhov pib ntxhib leveling yuam kev ntawm lub hauv paus phaj yuav tsum tsis pub tshaj 0.10/1000. Tom qab cov cement hardens, qhov kawg calibration yuav tsum tau, thiab kab rov tav yuam kev yuav tsum tsis pub tshaj 0.05/1000.
- Kev Kho Coupling:Rau kev sib txuas yooj yim txuas nrog lub reducer tsav ncej thiab lub cev muaj zog, radial hloov pauv yuav tsum tsawg dua lossis sib npaug li 0.3 hli. Lub taub hau qaij yuav tsum yog<1°.
- Rotation Direction:Thaum saib hauv qab ntawm cov khoom siv, lub impeller yuav tsum tig mus rau hauv ib qho kev taw qhia clockwise.
5. Kuaj Khiav & Kev Kho Kom Zoo
Kev soj ntsuam thiab kev saib xyuas tau zoo tuaj yeem ua kom lub neej ntev ntawm cov khoom siv.
- Tsis muaj-Load thiab Load Testing:Tsis muaj- kev ua haujlwm thauj khoom ntawm qhov ntsuas ceev tsis pub tsawg dua 2 teev yuav tsum ua ntej. Tom qab ib txwm tsis muaj- kev ua haujlwm thauj khoom, yuav tsum kuaj xyuas kom ntseeg tau tias tsis muaj kev cuam tshuam kev co thiab tsis muaj roj los ntawm cov ntsaws ruaj ruaj.
- Roj Hloov:Ob lub lis piam tom qab lub tshuab aerator tshiab ua haujlwm hauv kev thauj khoom, cov roj qias neeg yuav tsum tau ntws thiab hloov nrog cov roj tshiab. Tom qab ntawd, thaum lub sijhawm ua haujlwm ntev -, cov roj yuav tsum tau hloov txhua 4-6 lub hlis.
- Kev ntsuas kub ntsuas: Oil temperature should be observed during daily operation; if the temperature rise is >30 degree, lub tshuab yuav tsum tau nres kom pom qhov ua rau thiab kho ua ntej siv ntxiv.
- Kev tiv thaiv lub cev qhuav dej:Yog hais tias lub impeller lub cev qhuav dej tshwm sim (qhia los ntawm kev poob tam sim no thiab ploj ntawm hydraulic dhia), oxygenation poob qis, thiab lub tshuab yuav tsum tau nres tam sim rau kev tshuaj xyuas. Yog tias cov ntaub ntawv vortex vim yog lub pas dej me me, cov phiaj xwm baffle uas protrude saum cov dej theem tuaj yeem ntsia tau kom tsis muaj zog ntawm kev sib hloov.
