Mawu Oyamba

Ulusi mtundu matenthedwe mpweya wotuluka 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.
Tri-clamp matenthedwe gasi otaya mita kukula kuchokera DN15~DN100mm

Ubwino wake

Ulusi wamtundu 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 mitundu yonse ya muyeso umodzi kapena wosakanikirana wa gasi amatha kuyeza gasi ndi kuthamanga kwa 100Nm / s mpaka 0.1Nm / s, yomwe ingagwiritsidwe ntchito pozindikira kutayikira 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 kokhazikika mumkhalidwe wokhazikika (ndiko kuti, mawonekedwe ake sasintha), amafanana ndi mita yothamanga;
(10) 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:
Mtundu wa ulusi wa mpweya wotentha wa gasi womwe umagwiritsidwa ntchito kwambiri pamagetsi a Magetsi, kuyeretsa madzi, mafakitale a Petrochemical, Galasi, Ceramics ndi mafakitale a Zipangizo zomangira, ndipo amagwiritsidwa ntchito kwambiri poyezera gasi Wouma, monga Mpweya, Gasi Wachilengedwe, LPG gas, Biogas, ect. Koma kuchuluka kwa mpweya wotentha sikukanagwiritsidwa ntchito kuyeza Nthunzi, mpweya wa chinyezi ndi Ethyne.

Kuyika

Kuyika kwa mita yotentha ya gasi yotentha:
① Yang'anani zofunikira pakulowetsa ndi kutulutsa.
② Kuchita bwino kwa uinjiniya ndikofunikira pantchito yolumikizira mapaipi ndikuyika.
③ Onetsetsani kuwongolera kolondola ndi kulunjika kwa sensa.
④ Chitanipo kanthu kuti muchepetse kapena kupewa kukhazikika (monga kukhazikitsa msampha wotsitsa, kutsekereza kutentha, ndi zina).
⑤ Kutentha kwakukulu kololedwa ndi kutentha kwapakati ziyenera kuwonedwa.
⑥ Ikani cholumikizira pamalo amthunzi kapena gwiritsani ntchito chishango choteteza dzuwa.
⑦ Pazifukwa zamakina, komanso pofuna kuteteza chitoliro, ndikofunikira kuthandizira masensa olemera.
⑧ Palibe kukhazikitsa komwe kugwedezeka kwakukulu kuli
⑨ Kusawonekera m'malo okhala ndi mpweya wambiri wowononga
⑩ Palibe kugawana magetsi ndi ma frequency converter, makina owotcherera amagetsi ndi makina ena omwe amatha kusokoneza chingwe chamagetsi.

Kukonzekera kwatsiku ndi tsiku kwa ulusi wamtundu wamafuta othamanga mita:
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.
