Steam nthawi zambiri imawonedwa ngati yamphamvu m'mafakitale osiyanasiyana. Popanga chakudya, nthunzi imagwiritsidwa ntchito kuphika, kuyanika ndi kuyeretsa. Makampani opanga mankhwala amagwiritsa ntchito nthunzi pamitundu yonse yamachitidwe ndi njira, pomwe mankhwala amaugwiritsa ntchito pochotsa komanso kusunga kutentha ndi chinyezi. M'mafakitale amagetsi, nthunzi imapangidwa kuchokera ku boiler ndipo imagwiritsidwa ntchito kuyendetsa ma turbines omwe amapanga magetsi. Choncho mapaipi a nthunzi ndi ofunika kwambiri m'mafakitale osiyanasiyana, omwe amagwira ntchito ngati ngalande zonyamulira nthunzi kupita kumalo osiyanasiyana. Kuonetsetsa chitetezo ndi magwiridwe antchito, ndikofunikira kuyang'anira ndikuwongolera zomwe zili mkati mwa mapaipi awa. Apa ndipamene zida zimayamba kugwiritsidwa ntchito kuti muzitha kuyang'anira bwino kachitidwe ka nthunzi.
Kuyika kwa mapaipi a nthunzi kumatha kugwiritsa ntchito zinthu zingapo zoyezera zomwe zili zofunika kuti zigwire ntchito moyenera komanso moyenera, kuphatikiza kuthamanga, kutentha ndi kuthamanga kwa mpweya:
Pressure transmitter:Chipangizo choyezera kupanikizika chitha kugwiritsidwa ntchito kuwunika ndikuwongolera kuthamanga mkati mwa mapaipi, kupereka ndemanga zenizeni zenizeni kuti zithandizire oyendetsa kuti asunge mulingo woyenera kwambiri wa kupanikizika. Kuwerenga kosalekeza koperekedwa ndi transmitter kumathandizira kukonza mwachangu komanso kuthetsa mavuto munthawi yake kuti muteteze kayendedwe ka nthunzi. Zindikirani kuti popeza kutentha kwa nthunzi nthawi zambiri kumakhala kokwera kuposa malire ovomerezeka a ma transmitter wamba, miyeso ngati ma radiation ndi siphon amalimbikitsidwa kuti ateteze zida za zida. Zomangamanga zokhala ndi umboni wakale ndi zabwino ngati malo ogwirira ntchito ndi oyaka komanso maphulika.
Temperature transmitter:Kuwongolera kutentha ndikofunikira kwambiri pamachitidwe a nthunzi, kumakhudza mwachindunji momwe amapangira ndikugwiritsa ntchito nthunzi. Oyendetsa amatha kusintha ma boiler molingana ndi kuyeza kwa kutentha kuti asunge kutentha koyenera kuteteza vuto la condensation. Kuphatikiza apo, kuwerengera molondola kutentha kumatha kukhala kofunikira kuti muwonetsetse kuti njira zochepetsera nthunzi pazakudya ndi zamankhwala. Nthunzi yotentha kwambiri nthawi zambiri imakhala yochepera 600 ℃, chifukwa chake Pt100 ingakhale chinthu choyenera kuzindikira poyezera nthunzi.
Flow mita:Kuthamanga kwa nthunzi mkati mwa payipi kumatha kuzindikirika ndi mita yoyezera gasi. Ndi gawo lothandiza pakuwongolera kagayidwe & kufunikira ndi kasamalidwe ka mphamvu, kukhathamiritsa kugwiritsa ntchito nthunzi ndikuchepetsa zinyalala. Kutuluka kapena kutsekeka komwe kungachitike m'dongosolo kumatha kudziwika munthawi yake chifukwa cha kusagwirizana kwa kuchuluka kwakuyenda. Vortex flow mita yotengera mfundo ya karman vortex msewu ndiye chida choyenera chowongolera kuchuluka kwa ma volumetric amitundu yosiyanasiyana ya nthunzi ndi gasi. Momwemonso, popaka nthunzi yotentha kwambiri ndikofunikira kutsimikizira kuthamanga kwa mita kovomerezeka ndi kutentha kumagwirizana ndi momwe zilili.
Kuphatikizika kwa mphamvu, kutentha ndi zida zoyenda mumayendedwe a mapaipi a nthunzi zimalola kuwunika ndi kuwongolera kwathunthu. Mafakitale amakono nthawi zambiri amagwiritsa ntchito njira zowongolera zapamwamba zomwe zimagwiritsa ntchito deta kuchokera pazida izi kuti zisinthe ndikuwonjezera magwiridwe antchito. Monga momwe makina opangira nthunzi amatha kusinthiratu kutulutsa kwa boiler kutengera kuthamanga kwa nthawi yeniyeni komanso kuwerengera kutentha, sikuti kumangowonjezera mphamvu zamagetsi komanso kumakulitsa moyo wa zida poletsa zinthu zomwe zingayambitse kuwonongeka. Kuphatikiza apo, zomwe zasonkhanitsidwa kuchokera ku zidazi zitha kufufuzidwa kuti zizindikire zomwe zikuchitika komanso mawonekedwe, ndikupangitsa njira zolosera zokonzekera. Poyembekezera zovuta zomwe zingachitike zisanachuluke, malo amatha kuchepetsa nthawi yocheperako ndikuchepetsa ndalama zokonzera.
Pamene ukadaulo ukupita patsogolo, zida zanzeru ndi kusanthula kwa data kusinthiratu kasamalidwe ka mapaipi a nthunzi, ndikutsegulira njira yopita kunjira zokhazikika zamafakitale. Shanghai Wangyuan ndi zaka zopitilira 20 wopanga zida zokumana nazo ndikukhala ndi zomwe zikuchitika. Musazengereze kutilankhula nafe ngati muli ndi nkhawa zina zilizonse zokhudzana ndi zida zapaipi ya nthunzi.
