Taw qhia

Insertion type thermal gas mass flow meter yog ib hom kev ntsuas huab hwm coj uas.
Nws yog nrov nyob rau hauv cov ntawv thov kev lag luam yog txoj kev uas lawv tsim thiab tsim. Cov yam ntxwv tsis muaj qhov txav mus los, ze li qhov tsis muaj kev cuam tshuam ncaj qha los ntawm txoj kev ntws, yuav tsum tsis muaj qhov kub thiab txias kho thiab khaws qhov tseeb ntawm ntau yam ntawm cov nqi ntws. Cov yeeb nkab ncaj nraim tuaj yeem raug txo los ntawm kev siv dual-phaj ntws txias cov ntsiab lus thiab kev teeb tsa yooj yim heev nrog cov yeeb nkab intrusion tsawg heev.
Insertion hom thermal gas mass flow meter loj los ntawm DN40 ~ DN2000mm.

Qhov zoo

Insertion type thermal gas mass flow meter advantanges:
(1) Ntau qhov sib piv 1000: 1;
(2) Txoj kab uas hla loj, tus nqi qis qis, tsis muaj qhov poob siab;
(3) Kev ntsuas huab cua ncaj qha yam tsis muaj qhov kub thiab txias;
(4) rhiab heev rau kev ntsuas qis qis;
(5) Yooj yim rau tsim thiab xaiv, yooj yim rau nruab thiab siv;
(6) Tsim nyog rau txhua yam kev ntsuas ib zaug lossis sib xyaw ua ke tuaj yeem ntsuas cov pa nrog qhov nrawm nrawm ntawm 100Nm / s txog 0.1Nm / s, uas tuaj yeem siv rau kev kuaj pom roj;
(7) Lub sensor tsis muaj qhov txav mus los thiab qhov ntsuas qhov siab, thiab tsis cuam tshuam los ntawm kev vibration ntawm qhov ntsuas qhov tseeb. Nws muaj kev ua haujlwm zoo seismic thiab kev ntsuas kev ntseeg siab;
(8) Tsis muaj kev poob siab lossis poob siab me me.

Kev teeb tsa

Insertion type thermal gas mass flow meter installation:
① Txawm hais tias lub flowmeter tau nruab vertically lossis horizontally, khaws cov flowmeter nyob rau hauv lub xeev kab rov tav.
② Nyob rau hauv cov xwm txheej uas tsis siv roj nres lossis tsis siv roj nres yuav ua rau muaj kev cuam tshuam loj heev, kev hla yuav tsum tau teeb tsa.
③ Yuav tsum muaj tsawg kawg yog 10D ncaj yeeb nkab seem nyob rau hauv pem hauv ntej ntawm lub flowmeter thiab ib tug 5D (D yog cov yeeb nkab txoj kab uas hla) ncaj yeeb nkab seem ntawm lub rear.
④ Yog tias lub ntsuas hluav taws xob tau teeb tsa sab nraum zoov, lub hnub ci yuav tsum tau ntxiv kom tsis txhob tshav ntuj thiab nag.
⑤ Nco ntsoov tias tsis muaj qhov sib nqus muaj zog, muaj zog hluav taws xob thiab muaj zog txhua yam kev co nyob ze ntawm lub flowmeter.
⑥ Lub hauv av zoo li qub ntawm cov flowmeter yuav tsum txhim khu kev qha, tab sis nws tsis tuaj yeem koom nrog cov av muaj zog tam sim no.
⑦ Ib puag ncig ib puag ncig yuav tsum paub meej tias tsis muaj cov nyhuv corrosive ntawm aluminium alloy.
⑧ Xyuas kom meej tias cov roj ntws cov kev taw qhia yog raws li tus xub taw qhia ntawm lub flowmeter.
⑨ Kev ua haujlwm vuam raug txwv nyob rau hauv qhov chaw tawg.

Insertion hom thermal gas mass flow meter txij nkawm:
Nyob rau hauv kev ua haujlwm niaj hnub ntawm lub thermal gas loj flowmeter, xyuas thiab ntxuav lub flowmeter, nruj nreem xoob qhov chaw, nrhiav thiab daws qhov txawv txav ntawm lub flowmeter nyob rau hauv lub sij hawm, xyuas kom meej lub cev ua hauj lwm ntawm lub flowmeter, txo thiab ncua lub sij hawm ntawm hnav. Cheebtsam, Extend lub neej kev pab cuam ntawm lub flowmeter. Qee qhov flowmeters yuav dhau los ua fouling tom qab siv rau lub sijhawm, thiab nws yuav tsum tau ntxuav los ntawm pickling thiab lwm yam nyob ntawm seb qhov fouling.
