Kev sib qhia tswv yim kev paub nrog kaw cov txias txias yees duab: 10 xyoo ntawm kev pom ntawm kev teeb tsa, commissioning, thiab kev kho mob ua kom zoo dua qub

Kuv qhov kev paub ua ntej nrog kaw cov ntoo txias yog nyob rau hauv lub ru tsev uas muaj kev sib tw ua rau muaj kev sib tw ua rau muaj kev sib tw ua haujlwm dhau los vim tias muaj kev sib tw ua haujlwm dhau los vim muaj kev sib tw ua haujlwm dhau los vim tias muaj kev sib tw ua haujlwm dhau los vim tias muaj kev sib tw ua haujlwm dhau los vim tias muaj 3000RTs Niaj hnub no, Kuv xav qhia cov kev pom zoo no, feem ntau khi nrog cov ntxhiab tsw ntawm cov roj thiab hws cov ntsiab lus uas tsis tau hais meej hauv phau ntawv tab sis yog qhov tseem ceeb ntawm {}} chaw.

1. Kev teeb tsa theem: Tsis txhob cia "Foundation tsis muaj zog" ruin tag nrho cov kab ke

Ntau cov engineers maj mus nrhiav cov khoom siv uas tau txais cov xim av, tab sis xaiv qhov chaw kaw lub chaw txias rau kev txiav txim siab muaj kev nyuaj siab. Kuv nco qab ib qhov haujlwm uas lub pej thuam tau nruab sab nraud ntawm phab ntsa sab nrauv ntawm ib Rhiav. Raws li qhov tshwm sim, cov huab cua sov thiab vaum huab cua tsim hws ntawm phab ntsa hauv rau lub hlis, ua rau sab nrauv phab ntsa rwb thaiv tsev kom pwm. Kuv qhov kev paub tam sim no yog tias kev saib xyuas kev nkag tau ntawm tsawg kawg 1.5 metres yuav tsum tau tswj nyob ib ncig ntawm tus pej xeem tsis pub dhau 5 me me (xws li cua txias sab nraum zoov chav). Yog tias tus pej thuam tau teeb tsa ntawm lub ru tsev, cov cua tiv taus coefficient yuav tsum tau txiav txim siab. Rau cov tsev nyob ntau dua 30 metres hauv qhov siab, cua deflector yog pom zoo.

Feem ntau ntawm kev nthuav dav meej thaum lub hauv paus ping yog cov tsev ua vaj tse nyob yuav tsum muaj ntau dua lossis sib npaug ntawm C25, thiab theem ntawm C25, thiab qib ntawm cov phiaj hlau uas kos tau yuav tsum tau tswj hwm hauv ± 2mm. Xyoo tas los, thaum lub sijhawm lees paub ntawm ib qho project, peb pom tias 5 hli kev sib cav nyob rau qib theem, ua rau kev txo qis ntawm lub sijhawm txo lub sijhawm ua haujlwm, kev ua haujlwm. Cov piping sib txuas tseem yuav tsum tau ua tib zoo xav txog. Nws raug nquahu kom nruab ib qho y - hom kev lim dej ntawm ntau dua los yog sib npaug rau 40 mesh) rau cov dej txias inlet ntsiav tshuaj inlet yeeb nkab. Txwv tsis pub, vuam slag thiab xeb nyob rau hauv cov dej ncig teb yuav tawg sai sai cov kav dej kom ceev.

Ii. Kev Qhia Txog Sij Hawm: Cov kev txwv no tseem ceeb tshaj li phau ntawv.

Thawj qhov commissioning yog twv yuav raug hu ua kev ua haujlwm. Ib rooj plaub uas tshuav ib qho kev xav tau ntev tshaj plaws rau kuv: tus kheej, thaum tus kheej- commressle, uas tau ua rau muaj dej ntws ntau npaum li 0.8% (ib txwm muaj, nws yuav tsum yog<0.01%). It was later discovered that the fan inverter's startup ramp was set too steeply, resulting in uneven airflow distribution. My current commissioning process is: first, start the circulating water pump and run it for 30 minutes. Observe the water level in the collection pan for stability (normal fluctuation range: ±5mm). Then, gradually increase the fan speed. Simultaneously, use an infrared thermometer to monitor the temperature difference between the inlet and outlet water of the coils. High-quality equipment should maintain a steady temperature difference of 5-8°C.

Kev tswj hwm cov dej yuav tsum tau ua ntej ib hnub ib. Ib daim ntawv lab yuam ua tsis tau ntxiv ntxiv rau cov kab mob txuas, ua rau tooj liab cov yeeb nkab txuas ntxiv mus txog 1.2mm tuab tom qab peb lub hlis, halving tshav kub sib pauv efficiency. Nws raug pom zoo kom nruab qhov ntsuas online online (tswj cov khoom tsawg dua lossis sib npaug rau 1500μs / cm) nyob rau hauv cov dej txias. Thaum txoj kev coj ua tshaj 2000μs / cm, lub tshuab hla kev hla yuav tsum qhib kom ua haujlwm. Saib xyuas tshwj xeeb yuav tsum tau them rau Frost kev tiv thaiv thaum lub caij ntuj no. Xyoo tas los, ib qhov project nyob rau sab qaum teb tsis ua tiav rau cov kauj npog tag nrho, ua rau peb lub titanium kav dej khov khov thiab tawg ntawm -25 degree. Kev kho tus nqi ntau dua 80,000 yuan.

3. Kev ua haujlwm thiab txij nkawm: cov "hauv tsev -} Grown" cov hau kev yog ua tau zoo dua li cov twj siv.

Kev soj ntsuam niaj hnub ua haujlwm tau yooj yim thiab siv tau peb cov npe, ib qho saib rau cov suab kiv cua tsis zoo yog ua ntej kev puas tsuaj); Mloog rau Cavitation Mloog lub suab meshing ntawm cov reducer zog (lub suab zoo ib txwm yuav tsum yog tus khov kho "ntawm kev ua" "); Thiab kos cov dej hauv cov dej sau yias rau cov nyom tshuab (nws yuav tsum pom tseeb thiab pom). Tus neeg tebcuj ntawm cov nroj tsuag tshuaj tsim cov qauv hauv tsev siv PVC cov yeeb nkab. Lawv sau sediment txhua lub limtiam thiab saib cov teeb meem ntxov dua li kev kuaj sim.

Kev ntxuav tu yog cov haujlwm tshaj lij kev ua haujlwm. Ntau tus neeg ua haujlwm siv siab dua - cov pa dej siab, uas tuaj yeem tiv thaiv lub pvc staggered ntim thiab ua rau airflow luv- puag ncig. Txoj kev kom yog yog kom soak lub ntim nrog muag muag nrog ib lub suab, tom qab ntawd yaug nws lub zog (tsawg dua lossis sib npaug ntawm cov pob. Xyoo tas los, peb txhim kho peb cov txheej txheem ntxuav, ntsia ib lub chaw siv tshuaj tsis siv neeg hauv cov dej sau yias, thiab tsis tu ncua ntxiv kev xeb thiab cov khoom tsis tu ncua. Qhov no tau txuas ntxiv lub neej ntim txij li peb xyoos mus rau tsib.

IV. Cov hloov khoom dua tshiab thiab retrofits: txawm tias cov cuab yeej qub tuaj yeem tau txais lub neej thib ob

Qhov kev nyuaj tshaj feem ntau peb tau ntsib yog hloov dua siab tshiab 12-} xyoo galvanized steel kaw ntauwd rau stainless hlau. Cov cuab yeej qub ntawm cov qauv hlau yog corroded loj heev. Peb tau siv "kev txhawb nqa hauv siab xwm txheej + thoob plaws kev tiv thaiv corrosion" Lub retrofit nce tshav kub sib pauv ua haujlwm los ntawm 25% thiab txo tus nqi kho txhua xyoo los ntawm 40%. Qhov no qhia tias, dhau los ntawm kev siv hluav taws xob, cov cuab yeej qub tuaj yeem ua tiav cov txheej txheem tshiab.

Txhim kho cov tswv yim tswj kev ntse tswj cov tshuab feem ntau yields tsis tau txais txiaj ntsig. Xyoo tas los, peb tau nruab ib qho IOT -}. Los ntawm kev sau tiag -} Cov ntaub ntawv sijhawm ntawm Inlet thiab cov dej ntws, ua kom haum rau kev siv hluav taws xob, ua rau 60% txo cov khoom tsis ua haujlwm. Ntawm tshwj xeeb sau yog lub installation ntawm ib ultrasonic flowmeter los saib coil ntws. Thaum ntws tawm tsis meej pem, nws tuaj yeem muab cov kev txaus ntshai thaum ntxov {}} Qhov yooj yim dua li tos kom txog thaum tshav kub hloov ua ntej khom teeb meem.

Xaus: Kev paub yog tus kws qhia zoo tshaj plaws

Lub kaw txias ntauwd yuav tshwm sim yooj yim hauv cov qauv, tab sis tswj kav ntev}}}}}}}}}}}}}}}}}}} kev ua haujlwm ruaj khov yuav tsum tau muaj kev nplua nuj ntawm cov ncauj lus kom ntxaws. Kuv nco txog tus neeg muas zaub ib zaug nug kuv hais tias, "Vim li cas cov khoom siv uas koj muaj ib txwm kav ob lossis peb xyoos ntev dua?" Kuv teb tau yog, "Vim peb ib txwm nug cov lus nug 'vim li cas' hauv txhua qhov tawg." Cov neeg muaj roj gasy - Hmo ntuj kho, cov ntaub ntawv cov ntaub ntawv los ntawm kev xeem thiab cov ntaubntawv luv dua los ua kev txiav txim siab ua kom kuv siv thaum muaj kev daws teeb meem.

Thaum kawg, cov lus qhia tswv yim: ib txwm khaws ib lub hnab ntim khoom noj nyob hauv cov khoom txias ntauwd tswj cov txee. Tso nws nyob ze cov hluav taws xob Cheebtsam thaum cov av noo ze tshaj 85%. Qhov no zoo tiv thaiv hws hws -} induced luv luv. Txoj kev no tau ua haujlwm tau tsib xyoos, thiab kuv tsis tau muaj ib tus neeg sib cuag tau hlawv xwb. Tsis muaj qhov luv luv hauv O & M, tab sis tig txhua qhov "tsis tau npaj tseg" rau hauv "paub {{6} yog tus nqi ntawm kev paub.
