Mawu Oyamba

Insertion mtundu matenthedwe gasi otaya mita ndi imodzi mwa mtundu misa otaya mita amene.
Chodziwika mu ntchito zamafakitale ndi momwe amapangidwira ndikumangidwira. Mawonekedwewa alibe magawo osuntha, pafupifupi osatsekeka mowongoka mowongoka, samafunikira kutentha kapena kuwongolera kukakamiza ndikusunga kulondola pamitundu yosiyanasiyana yoyenda. Kuthamanga kwa mapaipi owongoka kumatha kuchepetsedwa pogwiritsa ntchito zida zapawiri-plate flow conditioning ndipo kukhazikitsa ndikosavuta ndi kulowerera kwa mapaipi ochepa.
Kuyika mtundu matenthedwe mpweya misa otaya mita kukula kuchokera DN40~DN2000mm.

Ubwino wake

Kuyika kwamtundu wa kutentha kwa gasi wothamanga mita advantanges:
(1) Wide range ratio 1000:1;
(2) Large m'mimba mwake, otsika mlingo otaya, negligible kuthamanga kutaya;
(3) Kuyeza kwachindunji kwa misa popanda kutentha ndi kupsinjika;
(4) Zovuta kwambiri pakuyezera kutsika kwapakati;
(5) Zosavuta kupanga ndikusankha, zosavuta kukhazikitsa ndikugwiritsa ntchito;
(6)Yoyenera muyeso umodzi kapena wosakanizika wa gasi woyezera Itha kuyeza gasi ndi liwiro la kutuluka kuchokera ku 100Nm/s kufika pa 0.1Nm/s, yomwe ingagwiritsidwe ntchito pozindikira kutuluka kwa mpweya;
(7) Sensa ilibe magawo osuntha ndi magawo omwe amamva kupanikizika, ndipo samakhudzidwa ndi kugwedezeka pa kulondola kwa kuyeza. Ili ndi magwiridwe antchito abwino a zivomezi komanso kudalirika kwakukulu koyezera;
(8) Palibe kutaya mphamvu kapena kuchepa kochepa kwambiri.
(9) Poyesa kutuluka kwa gasi, nthawi zambiri amawonetsedwa mu gawo loyendetsa voliyumu pansi pa chikhalidwe chokhazikika, ndipo kutentha kwapakati / / kukanikiza kusintha sikumakhudza mtengo woyezera. Ngati kachulukidwe kake kamakhala kofanana (ndiko kuti, kupangidwa kwake sikunasinthe), kumakhala kofanana ndi mita yothamanga;
(10) Pulagi-mu unsembe njira, kukhazikitsa ndi kukonza popanda kusiya kupanga, yosavuta kugwiritsa ntchito ndi kusamalira;
(11) Thandizani njira zambiri zoyankhulirana, monga kulankhulana kwa RS485, protocol ya MODBUS, ndi zina zotero, zomwe zingathe kuzindikira makina opangidwa ndi fakitale ndi kuphatikiza.

Kugwiritsa ntchito

Kugwiritsa ntchito mita yamafuta otenthetsera gasi:
Thermal gas air flow mita amagwiritsidwa ntchito kwambiri pamagetsi a Magetsi, kuyeretsa madzi, mafakitale a Petrochemical, Galasi, Ceramics ndi mafakitale a Zipangizo zomangira, ndipo amagwiritsidwa ntchito kwambiri poyezera gasi Wowuma, monga Mpweya, Gasi Wachilengedwe, LPG gasi, Biogas, ect. Koma kutentha Kuchuluka kwa gasi sikukanagwiritsidwa ntchito kuyeza Nthunzi, mpweya wa chinyezi ndi Ethyne.

Kuyika

Kuyika kwa mita yoyikira gasi yotentha:
① Mosasamala kanthu kuti flowmeter yayikidwa molunjika kapena yopingasa, sungani flowmeter kukhala yopingasa.
② Munthawi yomwe kuyimitsidwa mwangozi kwa gasi kapena kuyimitsidwa mwangozi kungayambitse kuwonongeka kwakukulu kosasinthika, njira yodutsa iyenera kuyikidwa.
③ Payenera kukhala gawo la chitoliro chowongoka cha 10D kutsogolo kwa flowmeter ndi 5D (D ndi m'mimba mwake) chitoliro chowongoka kumbuyo.
④ Chidacho chikayikidwa panja, mthunzi wa dzuwa uyenera kuwonjezeredwa kudzuwa ndi mvula.
⑤ Onetsetsani kuti palibe mphamvu ya maginito, mphamvu yamagetsi yamphamvu komanso kugwedezeka kwamphamvu kwamakina pafupi ndi flowmeter.
⑥ Kuyika kwa static kwa flowmeter kuyenera kukhala kodalirika, koma sikungagawidwe ndi maziko amphamvu apano.
⑦ Malo ozungulira ayenera kutsimikizira kuti palibe zowononga pazitsulo za aluminiyamu.
⑧ Onetsetsani kuti njira yoyendetsera gasi ikugwirizana ndi njira yolowera pa flowmeter.
⑨ Kuwotcherera ndikoletsedwa m'malo ophulika.

Kukonzekera kwa mita yoyikira gasi yotentha:
Pakugwira ntchito kwatsiku ndi tsiku kwa matenthedwe amagetsi otulutsa mpweya, fufuzani ndikuyeretsa flowmeter, limbitsani mbali zotayirira, pezani ndi kuthana ndi vuto la flowmeter lomwe likugwira ntchito munthawi yake, onetsetsani kuti flowmeter ikuyenda bwino, kuchepetsa ndi kuchedwetsa kuvala. zigawo, Kutalikitsa moyo utumiki wa flowmeter. Ena flowmeters adzakhala fouling pambuyo ntchito kwa nthawi, ndipo ayenera kutsukidwa pickling etc. malinga ndi mlingo wa kuipitsa.
