Taw qhia

QTLLntse gaskeeb kwmntwsmeter yog qhov ntws'meter' uas sib txuas ua haujlwm ntws, siab thiab ntsuas qhov ntsuas kubuas ua tauua kom siab, kub thiab compression factor kho. Nws muaj ntau yam qauv tsim thiab kev teeb tsa ua haujlwm kom tau raws li qhov sib txawv ntawm cov neeg siv khoom.QTLL Gas Roots Flow Meteryog dav siv nyob rau hauv lub tshav pob ntawm nroog gas thiab industrial gas flow ntsuas thiab nrhiav kom tau, thiabua tauua tau raws li tus neeg siv cov kev xav tau rau kev ntsuas siab, kev ntseeg siab lossis kev kuaj pom.

Qhov zoo

Gas cov hauv paus hniav ntws meter yog nrog cov neeg siab thiab rov ua tau zoo, nws txais yuav cov khoom siv siab-precision imported plua plav pov thawj stainless hlau tshwj xeeb bearings uas tuaj yeem ua kom lub neej ntev. Cov kev tsim qauv ntse ntse tuaj yeem tshawb xyuas qhov kub thiab txias, thiab ua haujlwm tsis siv neeg them nyiaj thiab kev kho qhov compression. Nrog rau kev siv tshuab dual-fais fab micro-powers, roj cov hauv paus hniav ntws ntsuas txhawb lub roj teeb ua haujlwm ntau dua 3 xyoos.
Piv nrog rau precession vortex flow meter, gas turbine flow meter yog nrog tsis tshua muaj siab poob, qis pib ntws thiab dav qhov sib piv.

Daim ntawv thov

Gas roots flow meter yog dav siv nyob rau hauv qhov ntsuas ntws ntawm cov pa roj, thee-rau-gas, inert gas, cua thiab lwm yam roj. Nws yog ib qho khoom siv ntsuas dej zoo tshaj plaws rau kev siv hluav taws xob hauv tsev thiab txawv teb chaws hauv nroog, roj av tshuaj, kev tshawb fawb tshawb fawb thiab lwm lub tuam tsev.

Installation Requirement rau Gas Roots Flow Meter
Ua ntej lub ntsuas dej ntws (tshwj xeeb tshaj yog cov kav dej tshiab lossis cov kav dej tom qab kho), cov kav dej yuav tsum tau muab tshem tawm kom tshem tawm cov impurities xws li vuam slag thiab xeb.

(1) Vertical installation
Thaum txhim kho vertically, cov roj inlet yuav tsum nyob rau sab saum toj, thiab cov cua ntws yuav ntws los ntawm sab saum toj mus rau hauv qab, uas yog, sab saum toj thiab hauv qab tawm. Lub tuam txhab xav kom cov neeg siv siv ntsug installation kom ntau li ntau tau. Tus kheej tu lub peev xwm ntawm rotor mus rau sundries;

(2) Kab rov tav installation
Thaum txhim kho kab rov tav, qhov axis ntawm qhov nkag thiab qhov hluav taws xob kawg ntawm lub ntsuas dej yuav tsum tsis txhob qis dua qhov axis ntawm cov kav dej kom tsis txhob muaj impurities nyob rau hauv cov roj los ntawm nyob rau hauv lub flow meter thiab cuam tshuam rau ib txwm ua haujlwm. Nyob rau tib lub sijhawm, lub ntsuas ntsuas flange yuav tsum tau txuas ncaj qha rau lub flange lim;

(3) Tsis hais txog kev teeb tsa ntsug lossis kab rov tav, lub rotor ncej hauv qhov ntsuas ntsuas yuav tsum nyob hauv txoj haujlwm kab rov tav.
