Inde, choyezera kuyenda kwa magetsi chamagetsi chingathe kuyikidwa moyima. Kuyikira (kopingasa kapena koyima) sikukhudza mfundo yoyezera, bola ngati chubu choyezera nthawi zonse chimakhala chodzaza ndi madzi oyendetsera mpweya ndipo mikhalidwe yoyikira ikukwaniritsa zofunikira.
Ma electromagnetic flow meter amagwira ntchito motsatira lamulo la Faraday la Electromagnetic Induction. Sensor imapanga mphamvu ya maginito mkati mwa chubu choyezera, ndipo madzi oyendetsera mpweya akamayenda kudzera mu mphamvu ya maginito iyi, chizindikiro cha magetsi chimapangidwa. Ma electrode amazindikira chizindikiro ichi, ndipo chosinthira chimawerengera kuchuluka kwa madzi malinga ndi liwiro la madzi.
Chifukwa chake, choyezera kuyenda kwa magetsi chamagetsi sichimafuna ngodya inayake yoyikira. Zinthu zofunika kwambiri ndikusunga kayendedwe ka madzi kokhazikika, kuonetsetsa kuti ma electrode akugwirizana bwino ndi madzi, komanso kuletsa mpweya kulowa mu chubu choyezera.
Malangizo Oyenera Okhazikitsa Oyima
Pa mapaipi oyima, nthawi zambiri amalimbikitsidwa kuyika madzi oyenda mmwamba.
Madzi akamapita mmwamba kudzera mu electromagnetic flow meter, pali zabwino zingapo zomwe zingapezeke:
Choyamba, payipiyo imakhala yodzaza kwambiri. Popeza zoyezera madzi zamagetsi zimafuna kuti chubu choyezera chizidzazidwa ndi madzi, madzi otuluka m'mwamba amathandiza kupewa matumba a mpweya ndi kusowa kwa mapaipi.
Chachiwiri, kuyenda mmwamba kumathandizira kuti muyeso ukhale wolimba pamene cholumikiziracho chili ndi tinthu tomwe timayimitsidwa kapena tolimba. Kuthamanga mmwamba kumathandiza kuti tinthu tisunthike ndi madzi ndipo kumachepetsa kuthekera kwa matope kulowa mkati mwa sensa.
Chachitatu, kuyenda mmwamba kwa mpweya n'kothandiza pa ntchito zomwe madziwo angakhale ndi thovu laling'ono la mpweya. Thovulo limapita mmwamba mwachibadwa ndi kuyenda kwa madzi m'malo mokhala mozungulira ma electrode, zomwe zingachepetse kusinthasintha kwa chizindikiro.
Pazifukwa izi, kuyika moyimirira mmwamba kumagwiritsidwa ntchito kwambiri pa ntchito monga kuyeretsa madzi otayira, madzi a mafakitale, mapaipi a mankhwala, ndi kuyeza matope.
Kodi Chiyeso Choyezera Mafunde a Magetsi Chingathe Kuyikidwa Molunjika ndi Downward Flow?
Kukhazikitsa koyima ndi madzi otsikira pansi n'kotheka, koma nthawi zambiri si chisankho chomwe chimakondedwa.
Nkhawa yaikulu ndi yakuti kuyenda pansi kungayambitse kuti chitolirocho chidzaze pang'ono, makamaka pamene:
* Paipi yotsika pansi pa madzi ili yotseguka kumlengalenga.
* Kupanikizika kwa msana sikukwanira.
* Kuchuluka kwa madzi m'thupi kumasintha kwambiri.
* Malo oikira ali pafupi ndi malo otulutsira mapaipi.
Ngati chubu choyezera sichinadzazidwe mokwanira, mpweya ungalowe mu sensa, zomwe zimapangitsa kuti zizindikiro zoyezera zisakhazikike komanso kuti kayendedwe ka madzi kasayende bwino.
Mwachitsanzo, ngati choyezera kuyenda kwa magetsi chayikidwa pa chitoliro choyimirira chisanafike malo otulutsira madzi, madziwo sangalowe mokwanira mu chubu choyezera. Pachifukwa ichi, choyezera kuyenda kwa madzi chikhoza kusonyeza kusinthasintha kwa madzi kapena kuchuluka kwa madzi kolakwika.
Ngati kuyika pansi sikungapeweke, kapangidwe ka payipi kayenera kuonetsetsa kuti sensa imakhalabe yodzaza ndi madzi nthawi zonse.
Nchifukwa chiyani chitoliro chonse chili chofunikira pakuyika choyima?
Chitoliro chonse ndi chimodzi mwazofunikira kwambiri pa mita yoyendera magetsi yamagetsi.
Ma electrode omwe ali mkati mwa sensa amafunika kukhudzana mwachindunji ndi madzi oyendetsera mpweya kuti ayesere mphamvu yamagetsi yoyambitsidwa molondola. Ngati mulingo wamadzimadzi utsika pansi pa ma electrode kapena mpweya ukalowa mu chubu choyezera, chizindikiro chamagetsi chimakhala chosakhazikika.
Mavuto omwe amadza chifukwa cha chitoliro chosadzazidwa ndi awa:
* Kuwerenga kwa kayendedwe ka madzi kosakhazikika
* Kuyeza kolakwika kwa kayendedwe ka madzi
* Kusintha kwadzidzidzi kwa chizindikiro chotulutsa
* Palibe chizindikiro cha kuyenda kwa madzi ngakhale madzi akuyenda
Kuti mupewe mavuto amenewa, pewani kuyika ma electromagnetic flow mita:
* Pamalo okwera kwambiri pa payipi pomwe mpweya ungaunjikane.
* Pamaso pa gawo lotsika pomwe kupanikizika koyipa kungachitike.
* Pafupi ndi malo otulutsira madzi omwe chitolirocho sichingakhale chodzaza.
Malo abwino nthawi zambiri amakhala malo otsika a payipi kapena gawo lomwe mphamvu yokwanira yotsika pansi ingathandize kuti payipiyo ikhale yodzaza.
Kukhazikitsa Koyima kwa Mapulogalamu Osiyanasiyana
Kugwiritsa Ntchito Madzi Oyera
Poyezera madzi oyera, kukhazikitsa mopingasa komanso mopingasa kungapereke magwiridwe antchito odalirika. Kukhazikitsa mopingasa nthawi zambiri kumasankhidwa pamene dongosolo la payipi likufunikira kapena pamene malo ndi ochepa.
Kugwiritsa Ntchito Madzi Otayira ndi Madzi Otayira
Pa madzi otayira, matope, matope a m'migodi, ndi zakumwa zina zomwe zili ndi zinthu zolimba zopachikidwa, kuyika pamwamba molunjika nthawi zambiri kumakhala kopindulitsa.
Kuyenda kwa madzi mmwamba kumathandiza kuchepetsa kuthekera kwa zinthu zolimba kukhazikika pansi pa chubu choyezera, kukonza kukhazikika kwa nthawi yayitali ndikuchepetsa zofunikira pakukonza.
Kugwiritsa Ntchito Mankhwala
Pa mankhwala amadzimadzi, kuyika koyima kungagwiritsidwenso ntchito. Komabe, chisamaliro chiyenera kuperekedwa pakugwirizana ndi zinthu, kukhazikika, komanso kupewa kusonkhanitsa mpweya mupaipi.
Zofunikira pa Chitoliro Cholunjika pa Kuyika Koyima
Ngakhale kuti ma electromagnetic flow meter sakhudzidwa kwambiri ndi kusokonezeka kwa kayendedwe ka madzi poyerekeza ndi ma flow meter ena, kuyika mapaipi olunjika bwino kumalimbikitsidwabe.
Choyezeracho chiyenera kuyikidwa kutali ndi magwero amphamvu a chisokonezo monga:
* Mapampu
* Ma Valves
* Zigongono
* Zochepetsera kapena zokulitsa
Kayendedwe ka madzi kokhazikika kumathandiza kuti muyeso ukhale wolondola komanso wobwerezabwereza.
Zina Zoganizira Panthawi Yoyikira Yoyimirira
Mukayika choyezera kuyenda kwa magetsi molunjika, ganizirani mfundo izi:
1. Yang'anani momwe madzi akuyendera
Nthawi zonse ikani motsatira muvi wolozera kayendedwe ka madzi womwe walembedwa pa thupi la sensa. Kulozera kayendedwe kolakwika kungakhudze makonda ndi magwiridwe antchito a muyeso.
2. Onetsetsani kuti nthaka yake yakhazikika bwino
Ma electromagnetic flow meter amafunika nthaka yabwino chifukwa chizindikiro choyezera ndi chaching'ono kwambiri. Kukhazikika bwino kumathandiza kuchepetsa kusokoneza magetsi ndikuwonjezera kukhazikika kwa chizindikiro.
3. Pewani kusonkhanitsa mpweya
Ikani choyezera pamalo pomwe mpweya sungasonkhanitsidwe mosavuta. Ngati mpweya ukuyembekezeka kuphulika, nthawi zambiri kuyika mmwamba moyimirira kumakhala bwino.
4. Ganizirani za njira yopezera malo okonzera zinthu
Onetsetsani kuti pali malo okwanira kuzungulira sensa ndi chosinthira magetsi kuti muyang'ane, mulumikiza mawaya, komanso kuti mukonzenso mtsogolo.
Choyezera kuyenda kwa magetsi chamagetsi chingathe kuyikidwa moyimirira, ndipo kuyika moyimirira kumagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Kapangidwe koyenera kwambiri ndi chitoliro choyimirira chokhala ndi madzi oyenda mmwamba, chifukwa chimathandiza kusunga chitoliro chonse, chimachepetsa kusokoneza kwa thovu la mpweya, komanso chimathandizira kukhazikika kwa muyeso.
Chofunika kwambiri si ngati malo oikirawo ndi oyima kapena opingasa, koma ngati choyezera kuyenda kwa magetsi chamagetsi chingagwire ntchito bwino ngati chili ndi chubu choyezera chodzazidwa bwino komanso chokhazikika bwino. Zofunikira izi zikakwaniritsidwa, choyezera kuyenda kwa magetsi chamagetsi choyimitsidwa molunjika chingapereke muyeso wolondola komanso wodalirika wa kuyenda kwa madzi.
