Cov chaw lag luam tsis xav tau cov kiv cua nrov dua-lawv xav tau cov huab cua zoo dua. Thaum cov neeg ua haujlwm hauv cov mines thee, cov nroj tsuag tshuaj, lossis chav boiler yws txog cov suab nrov cuam tshuam kev sib txuas lus - lossis thaum pab pawg saib xyuas qhia ntxov ntxov ntawm kev coj tus kheej los ntawm kev vibration - lub hauv paus ua rau tsis tshua muaj "huab cua ntau dhau." Nws yog feem ntau tsis zoo engineered low-suab ntxuam Kev sib xyaw ua ke: mismatched zoo li qub siab nkhaus, tsis sib npaug rotors, los yog vaj tse uas ua kom nrov resonance es tsis txhob damping nws.
Peb tau sim ntau dua 47 axial thiab centrifugal units hla peb lub tshuab hluav taws xob thermal hauv Shandong - txhua qhov thov "kev ua haujlwm ntsiag to." Tsuas yog 11 tau ntsib ISO 5801 suab lub zog txwv ntawm kev thauj khoom tag nrho. Tus so siab tshaj 82 dB(A) ntawm 1 meter - tsis tuaj yeem nyob ze ntawm cov tswj vaj huam sib luag lossis rau 8-teev hloov. Lub ntiaj teb tiag-lub suab nrov kiv cua kev ua tau zoo tsis tau txhais los ntawm catalog decibel thov. Nws tau ntsuas hauv tus neeg teb xov tooj txo qis qaug zog, ua rau lub neej txuas ntxiv, thiab lub zog txuag thaum tus kiv cua tsis tawm tsam nws tus kheej.
Dab tsi Ua Ntxuam Ntxuam Tsawg-Ntse-Tshaj Daim Ntawv Sau
Tus kiv cua tsis tshua muaj suab nrov pib nrog kev qhuab qhia aerodynamic - tsis yog qeeb RPM xwb. Hniav suav cov teeb meem: 7-hnav impellers ntawm high-pressure centrifugals txiav lub suab nrov los ntawm 6-9 dB piv rau 5-hnav sib npaug. Tab sis hniav geometry ib leeg ua tsis tau yam tsis muaj precision manufacturing. Peb pom 0.08 hli runout nyob rau hauv tus neeg sib tw 9-19 series impeller ua rau 12 dB ntsia hlau loj ntawm 1,750 Hz - ncaj qha sib tshooj tib neeg hais lus ntau zaus. Tias yog vim li cas dynamic ntsuas rau G2.5 (ib ISO 1940-1) tsis xaiv. Nws yog non-negotiable.
Cov qauv xa suab nrov dhau lawm. Nyias-gauge casings resonate zoo li drumheads. Peb cov ntaub ntawv teb qhia tau hais tias titanium-kiv cua vaj tse txo cov qauv kev sib kis los ntawm 40% piv rau cov pa roj carbon steel-txawm tias nyob ntawm huab cua zoo ib yam. Tab sis titanium tsis yog ib txwm xav tau. Stiffened ob-phab ntsa tsim nrog constrained-txheej txheej damping nyob rau hauv nruab nrab-ntau qauv xa 9-11 dB(A) kev txhim kho ntawm ib nrab ntawm tus nqi.
Installation yuam kev sabotage txawm qhov zoo tshaj plaws tsim. Mounting lub ru tsev axial kiv cua ncaj qha mus rau lub teeb purlins? Qhov ntawd hloov tag nrho lub ru tsev mus rau hauv ib lub suab nrov. Peb qhia kom meej cov roj hmab-cais mounts-thiab xyuas lawv nrog accelerometer nyeem thaum ua haujlwm. Yog tias kev co siab tshaj 4.5 mm / s RMS ntawm cov kabmob, peb rov ntsuas tag nrho cov kab ke. Tsis yog tus kiv cua. Lub interface.
Kev siv hluav taws xob tsis muaj kev txi - Nws yog Amplified
Qee qhov xav tias suab nrov qis txhais tau hais tias qis zog. Tsis yog. Tus kiv cua tsis zoo ua haujlwm ntawm 62% kev ua haujlwm thaum qw ntawm 88 dB (A). Cov kiv cua uas muaj suab nrov zoo sib xws hits 81% kev ua haujlwm ntawm 67 dB(A) -vim nws ua haujlwm ze nws qhov chaw siab tshaj plaws aerodynamic, tsis choked lossis overloaded.
Siv FBD series tawg-pov thawj hauv zos cua ntxuam. Nws cov counter-rotating dual-theem tsim txav 32,000 m³ / h ntawm 3,200 Pa zoo li qub-tab sis rub 18% tsawg dua tam sim no tshaj ib theem sib npaug ntawm tib lub luag haujlwm taw tes. Vim li cas? Txo swirl poob ntawm theem txiav turbulence-induced luag. Tsawg turbulence txhais tau tias cua sov tsawg, suab nrov tsawg, thiab qis dua kW xav tau ib 1,000 m³ / h.
Peb taug qab qhov no hauv lub sijhawm tiag tiag. Ib tsob ntoo cement retrofitted rau 9-19 boiler thawj kiv cua nrog suab nrov sib txawv. Kev txuag hluav taws xob txhua xyoo: 1.2 GWh. Kev txo suab nrov ntawm cov chaw nres tsheb: 14 dB(A). Lub sijhawm them rov qab: 11 lub hlis - tsis yog los ntawm kev lag luam "ntev", tab sis los ntawm kev ntsuas aerodynamic nce thiab txo cov khoom poob.
Customization yog qhov twg Standard Catalogs Fail
"Low-noise" txhais tias tsis muaj dab tsi tsis muaj ntsiab lus. Lub tshuab nqus pa tawm hauv lub qhov yuav tsum nyob ntsiag to * thaum * tiv taus 400 ° C roj surges. Lub kiv cua desulfurization xav tau kev tiv thaiv corrosion * ntxiv * sub-70 dB(A) kev ua haujlwm ntawm chloride-laden pos huab. Off-the-shelf specs poob ntawm no.
Yog li ntawd, kev tsim khoom sib xyaw ua ke tseem ceeb. Thaum tus neeg siv khoom xav tau tus kiv cua titanium rau qhov hnyav H₂S ib puag ncig-thiab thov ≤65 dB(A) ntawm 3 meters-peb tsis tau txais qhov chaw. Peb machined lub impeller nyob rau hauv-tsev, welded lub tsev nrog argon-backing, thov ceramic-coated bearings, thiab validated acoustic tso zis rau peb anechoic xeem rig. Tag nrho lub sij hawm xa tuaj: 14 lub lis piam. Tsis muaj kev cuam tshuam rau lub suab nrov, kev ncaj ncees ntawm cov khoom siv, lossis kev xa khoom.
Qhov tseem ceeb customization levers peb siv txhua hnub:
Hniav cheb optimization rau tshwj xeeb duct system impedance Acoustic hauv ob sab phlu tso hloov mus rau qhov tseem ceeb zaus bands-tsis yog daim pam npog Motor-mount decoupling cais electromagnetic hum los ntawm mechanical vibration Explosion-proof certification txoj kev Ua raws li IEC 60079-0/1/31 - Tsis yog tsuas yog ntsia liaj qhov rooj ntawm cov ntaub ntawv Xaiv Koj Tus Ntxuam Ntxuam Tom ntej no: Kev Tshawb Xyuas Ua Haujlwm
Ua ntej qhia meej, nug cov lus nug no - tom qab ntawd txheeb xyuas cov lus teb nrog cov ntawv xeem, tsis yog daim ntawv qhia:
Puas yog lub zog suab ntsuas raws ISO 5801 - lossis tsuas yog lub suab siab ntawm ib qhov deb? Puas yog qhov ua tau zoo nkhaus qhia qhov siab tshaj> 75% ntawm koj qhov chaw ua haujlwm xav tau? Puas yog bearing lub neej xam raws li qhov tseeb L10 load-tsis theoretical max RPM? Lawv puas tuaj yeem muab cov neeg thib peb NVH (suab nrov-vibration-harshness) validation rau koj qhov tseeb configuration? Ntawm Zibo Hongcheng Ntxuam Co., Ltd., txhua lub suab qis kiv cua nkoj nrog daim ntawv pov thawj acoustic kos npe thiab daim ntawv qhia kev ua tau zoo - tsis yog ib qho ntaub ntawv xwb. Peb tsim qhov twg airflow raws li kev lav ris: 9,000 m² ntawm precision machining, dynamic balancing, thiab real-load testing nyob rau hauv simulated industrial tej yam kev mob. Vim tias qhov txias txias yuav tsum tsis yog khoom kim heev. Nws yuav tsum yog lub hauv paus rau kev nyab xeeb, ua haujlwm tau zoo, thiab ruaj khov.
Rau cov engineers uas ntsuas kev ua tau zoo hauv decibels zam thiab kilowatts tau txais kev cawmdim - tsis yog cubic meters txav - tiam tom ntej ntawm cov tshuab hluav taws xob qis qis tau ua haujlwm. Tsis nyob hauv lab. Hauv mines. Hauv tsev boiler. Hauv thaj chaw muaj tshuaj lom neeg. Qhov twg kev ntseeg tsis tau cog lus tseg. Nws ua pov thawj.
