Yatsekedwa-Circuit Cooling Tower
Zotsekera{0}zinsanja zoziziritsa kukhosi zotsekedwa ndi zida zomwe zimagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamakina, makamaka pochiritsa kutentha, kuziziritsa, zoziziritsira mpweya ndi zina. Zochita zawo ndizofunikira kwambiri pakugwira ntchito moyenera komanso moyenera kwa zida. Nkhaniyi ifotokoza mwatsatanetsatane magawo a magwiridwe antchito aanatseka-nsanja zozirira zozungulira pakugwiritsa ntchito makina, kuthandiza owerenga kumvetsetsa bwino mawonekedwe ndi ubwino wa zida.
Basic Working Mfundo
Zotsekedwa-zinsanja zoziziritsira zozungulira madzi ozizira otentha kudzera m'madzi ozungulira kuti zitsimikizire kuti zida zamakina zimagwira ntchito moyenera. Amakhala ndi mapampu amadzi ozungulira, nsanja zozizirira komanso zida zopangira madzi. Madzi otentha akalowa munsanja yozizirira kudzera pa mpope wamadzi wozungulira, amawathira molingana ndi kudzaza kuchokera pamwamba kuti asamutsire kutentha ndi mpweya woziziritsa womwe umachokera pansi.
Panthawi yozizira, kutentha kwa madzi otentha kumatengedwa ndi mpweya wozizira, kuchepetsa kutentha kwa madzi. Madzi ozizirawo amawapoperanso kuzipangizo zamakina kuti agwiritsidwenso ntchito.
Zofunikira Zogwirira Ntchito
Waukulu ntchito magawo aanatseka-nsanja zozirira zozungulirakwa makina ogwiritsira ntchito amaphatikizapo kuziziritsa, kugwira ntchito bwino, kugwiritsa ntchito mphamvu ndi mphamvu zochizira madzi.
Kuzizira kozizira ndiye chizindikiro chofunikira kwambiri cha magwiridwe antchito, kuwonetsa kuzizira kwa zida. Nthawi zambiri amayezedwa mu kilowatts (kW).
Kuchita bwino kumatanthawuza chiŵerengero cha mphamvu ya kutentha yomwe imatembenuzidwa pa nthawi ya unit ku mphamvu yogwiritsidwa ntchito, yowonetsedwa ngati peresenti.
Kugwiritsa ntchito mphamvu ndi mphamvu zamagetsi zomwe zimagwiritsidwa ntchito panthawi yogwira ntchito, zomwe zimakhudza mwachindunji mtengo wa chipangizocho.
Mphamvu yochizira madzi imatanthawuza kutha kwa nsanjayo kuthana ndi zonyansa m'madzi, monga mpweya wosungunuka ndi kuuma.
Ma Parameter Ena Ofunika
Mulingo waphokoso: Ndiwofunikira kwambiri m'malo omwe mukufuna kuti pakhale bata.
Kulimbana ndi zinthu komanso dzimbiri: Zofunikira m'malo apadera okhala ndi mpweya wowononga kapena zamadzimadzi.
Zofunikira Zosamalira
Kusamalira moyenera ndikofunikira pa moyo wautumiki wa zida: Pakagwiritsidwe ntchito, zida zosasunthika zimafunikira kuyang'aniridwa ndi kukonzedwa pafupipafupi, pomwe zida zosunthika zimafunikira kukonza ndikusinthidwa munthawi yake. Mfundo zazikuluzikulu zogwirira ntchito zaanatseka-nsanja zozirira zozunguliraakuphatikizapo mafani, mapampu amadzi ndi zinthu zamagetsi, ndi zofunika kukonza motere:
Kukonza mafani:
Mafani apadera a nsanja zozizirira amatengedwa, zokhala ndi mphamvu zambiri, kugwiritsa ntchito mphamvu zochepa, phokoso lochepa komanso kuchuluka kwa mpweya. Kuyang'ana tsiku ndi tsiku kuyenera kuphatikizapo kuyang'ana ngati akutha, kutayikira kapena kupindika kwa ma fan, ndikuwonetsetsa kuti mafuta opaka bwino (kuwonjezera mafuta opaka kapena mafuta ngati pakufunika) kuti agwire bwino ntchito.
Kusamalira pampu:
Mapampu odzipatulira okhala ndi mutu wocheperako komanso kutuluka kwakukulu ali ndi zida zowonjezera kutsitsi, kuchepetsa kugwiritsa ntchito mphamvu ndikuwonjezera moyo wautumiki wa zida. Kuyang'ana pafupipafupi kuyenera kuyang'ana kutsekeka kapena kuvala kwa zoyika pampu, ndikuwonetsetsa kuti zosindikizira za shaft shaft sizitayikira (kuteteza kutayika kwa madzi ndi kuchepetsa mphamvu). Kuthetsa mavuto ndi kusintha chigawocho kuyenera kuchitidwa mwamsanga ngati pali vuto.
Kukonza gawo lamagetsi:
Yang'anani pafupipafupi ma contactor, ma relay, owongolera ndi zinthu zina zamagetsi zotayirira, mawaya okalamba ndi kutentha kwachilendo. Tsukani kabati yoyendetsera magetsi pafupipafupi kuti fumbi lisawunjike kuti lisapangitse mabwalo afupiafupi kapena kulephera kwazinthu.
Kukhathamiritsa kasamalidwe ka magawo osinthira:
Kuti tithandizire kukonza kwa ogwiritsa ntchito, kampani yathu imatengera mapangidwe ogwirizana azinthu zazikulu (monga mafani ndi mapampu amadzi). Izi zimathandizira kuchepetsa kubweza kwa zida zotsalira, kufewetsa njira zokonzetsera, ndikupangitsa kuyang'anira ndi kukonza zida kukhala zokhazikika komanso zogwira mtima.
Chidule
Magawo a magwiridwe antchito aanatseka-nsanja zozirira zozungulirakwa makina ogwiritsira ntchito ndi zinthu zazikulu zomwe zimakhudza magwiridwe antchito ndi magwiridwe antchito. Posankha ndi kugwiritsa ntchito nsanja zotere, kuganizira mozama magawo osiyanasiyana ogwirira ntchito kutengera zosowa zenizeni komanso zofunikira zachilengedwe ndikofunikira kuti zitsimikizire kuti zimagwira ntchito bwino komanso kuwongolera kugwiritsa ntchito mphamvu. Komanso, positi{2}}njira zokonzetsera zogula ndi zofunika kwambiri kuti ziwonjezeke moyo wantchito ya chipangizochi.
