Muyeso wa Kuyenda kwa Gasi Wachilengedwe

Mabizinesi amakumana ndi zovuta zazikulu pakuwongolera njira, kuwongolera bwino komanso kuwongolera mtengo popanda zolemba zolondola zakuyenda kwa gasi, makamaka m'mafakitale omwe gasi amagwiritsidwa ntchito ndikukonzedwa mokulira pansi pamikhalidwe yosiyanasiyana. Popeza kuyeza kolondola kwa gasi wachilengedwe ndikofunikira pakuwongolera magwiridwe antchito, chitetezo chogwira ntchito komanso kutsata malamulo, kusankha mita yoyendera bwino ya gasi yachilengedwe yatembenukira ku lingaliro lachidziwitso, lomwe limapangitsa kuti pakhale zokolola zambiri, kutsata chilengedwe komanso kugwiritsa ntchito ndalama.

Chifukwa Chiyani Kuyeza Kuyenda Kwa Gasi Ndikofunikira Pamakampani?

Kuphatikiza pazifukwa zomwe zili pamwambazi, kuyeza kolondola kwa kayendedwe ka gasi kumasiya ntchito yonseyo, kotero kuti kutulutsa komwe kungachitike komanso kugwiritsa ntchito kwambiri kutha kuwoneka mosavuta. Kuwonetsa lipoti latsatanetsatane lokhudza kugwiritsidwa ntchito kwa gasi ndi kutulutsa mpweya m'mafakitale ambiri, pomwe miyeso yolondola imathandizanso kutsata malamulo okhudzana ndi zofunikira zachilengedwe ndi chitetezo.

Komanso, kusinthasintha kwamphamvu kwa gasi kumawonetsa kutsekeka, kutayikira kapena kukonza mwapadera kuyenera kuchitidwa kuti athetse zoopsa zomwe zingachitike. Ndiyeno chitanipo kanthu kuthetsa mavutowo ngati kuli kofunikira.

Zofunikira Zofunikira za Mamita Oyenda Gasi

Pali zinthu zambiri zomwe ziyenera kuganiziridwa musanasankhe mita yoyendera gasi yoyenera, kuphatikiza koma osati ku:

✤Mtundu wa gasi

✤Zidziwitso zamayendedwe

✤Zikhalidwe zachilengedwe

✤Malo ogwirira ntchito

✤kupanikizika & kutentha

✤zolinga zoyembekezeredwa

✤kukhazikitsa & kukonza

Kupatula pa mfundo zomwe zatchulidwa pamwambapa, zofunikira zolondola ndizoyenera kuziganizira pazolakwika zosiyanasiyana zovomerezeka. Kulekerera zolakwika pang'ono kumafunidwa m'mafakitale apadera monga machitidwe amankhwala ndi kupanga mankhwala. Kupanikizika ndi kutentha ndi malire posankha ma mita oyenda bwino, nawonso. Mamita amayenera kupimidwa ndi mikhalidwe yovuta kwambiri popanda kusokoneza magwiridwe antchito amphamvu kwambiri. Zimatanthawuza kuti kudalirika kwa ma flow meters mumikhalidwe yotereyi ndikofunikira kwambiri pakugwira ntchito kwanthawi yayitali.

Mavuto Pakuyezera Kuyenda Kwa Gasi

Gasi wachilengedwe, monga gwero la mphamvu zoyeretsera, akugwiritsidwa ntchito mochulukira, ndipo gawo lake lamagetsi limakwera chaka chilichonse. Ndi chitukuko cha Pulojekiti ya Paipi ya Gasi ku West-East ku China, kufalikira kwa gasi wachilengedwe kukukulirakulira, kupangitsa kuyeza kwa gasi wachilengedwe kukhala gawo lofunikira.

Pakadali pano, kuyeza kwa gasi wachilengedwe kumagwiritsidwa ntchito m'malo ogulitsa, ndipo muyeso ku China umadalira metering ya volumetric. Gasi wachilengedwe amaperekedwa m'njira ziwiri: gasi wapaipi (PNG) ndi gasi woponderezedwa (CNG).

Mamita ena amapangidwa malinga ndi zofunikira, monga monyanyiramawu otsika komanso apamwamba. Miyendo yoyendera yomwe imakhala yabwino komanso yothamanga kwambiri imatsimikizira kuwerengera kosalekeza komanso kolondola. Kukula kwakung'ono kapena kwakukulu ndi chinthu china choyenera kuganiziridwa mwapadera kuyenera kwa gawo lililonse la mita yothamanga.

Mfundo Yogwirira Ntchito

Meta yoyendera gasi imagwira ntchito poyeza kuchuluka kwa gasi wotumizidwa kudzera papaipi. Kawirikawiri, kuthamanga kwa mpweya ndi ntchito ya liwiro la gasi ndi gawo lapakati pa chitoliro. Kuwerengera kumayenderana ndi ma aligorivimu otsogola, momwe mphamvu za gasi zachilengedwe zimasiyanasiyana malinga ndi kutentha, kupanikizika komanso mawonekedwe amadzimadzi.

Kugwiritsa Ntchito Gasi Flow Meters

Ubwino ndi Kuipa kwa Mitundu Yoyenda ya Gasi

Zachidziwikire, palibe ukadaulo umodzi kapena mita yomwe ingakwaniritse zofunikira zonse zamaukadaulo. Tekinoloje zinayi zofananira zoyezera gasi zimagwiritsidwa ntchito masiku ano pokonza mafakitole, zomwe zimakhala ndi mphamvu ndi zolephera zomwe zimafanana. Ndizotheka kupewa zolakwika zodula mutamvetsetsa zabwino ndi zovuta zake.

No.1 Electromagnetic Flow Meters

Ma electromagnetic flow mita amagwira ntchito motsatira mfundo ya Faraday's Law of induction. Koyilo yamagetsi mkati mwa mag flow mita imapanga mphamvu yamaginito ndiyeno ma elekitirodi amatha kuzindikira mphamvu yamagetsi. Mphamvu yamagetsi yamagetsi imasintha ndi mphamvu zotere madziwo akamadutsa mutoliro. Pamapeto pake, zosintha zotere zidzamasuliridwa kuti ziziyenda.

Ubwino	kuipa

No.4Coriolis Misa Flow Meters

Kugwedezeka kwa chubu kumasintha ndi kuthamanga kwapakati. Kusintha kotereku kwa kugwedezeka kumatengedwa ndi masensa kudutsa chubu ndiyeno kusinthidwa kukhala kuthamanga.

Ubwino	kuipa
Kuyeza kwachindunji kwa misa;	Palibe magawo osuntha;
Osasokonezedwa ndi kuthamanga, kutentha ndi kukhuthala;	Kugwedezeka kumachepetsa kulondola pamlingo wina;
Osafunikira magawo olowera ndi kutulutsa.	Zokwera mtengo

Kusankha mita yoyenera yoyendera gasi kumaphatikizapo kusanja kulondola, kulimba, ndi mtengo kuti zigwirizane ndi zosowa zenizeni za pulogalamuyo. Kusankha kodziwa bwino sikumangowonjezera magwiridwe antchito komanso kumathandizira kutsata malamulo ndi chitetezo. Pomvetsetsa mitundu yosiyanasiyana ya mita komanso kuyenerera kwawo pazinthu zosiyanasiyana, mafakitale amatha kuchita bwino, kuchepetsa ndalama, ndikuwonetsetsa kudalirika kwa machitidwe awo. Kupanga chisankho choyenera pamapeto pake kumabweretsa ntchito yamphamvu, yokhazikika yomwe ingakwaniritse zomwe zikuchitika komanso zovuta zamtsogolo.
