Chosinthira kutentha cha pamwamba chodulidwa: mfundo, kugwiritsa ntchito ndi chitukuko chamtsogolo

Chosinthira kutentha chokokedwa ndi mtundu wa zida zosinthira kutentha zogwira mtima, zomwe zimagwira ntchito yofunika kwambiri m'mafakitale azakudya, mankhwala, mankhwala ndi mafakitale ena. Kudzera mu kapangidwe ka makina ndi njira yogwirira ntchito yapadera, mtundu uwu wa chosinthira kutentha umathetsa vuto la chosinthira kutentha chachikhalidwe pothana ndi kukhuthala kwakukulu komanso zinthu zosavuta kukulitsa. Pepalali lidzasanthula mokwanira chosinthira kutentha chokokedwa, chida chofunikira kwambiri chamafakitale, kuchokera ku mfundo zogwirira ntchito, mawonekedwe a kapangidwe kake, minda yogwiritsira ntchito komanso zomwe zikuchitika mtsogolo.

 Choyamba, mfundo yogwirira ntchito ndi kapangidwe ka chotenthetsera kutentha pamwamba chofufutidwa

Mfundo yaikulu yogwirira ntchito ya chosinthira kutentha pamwamba chomwe chasindidwa ndikukanda mosalekeza pamwamba pa chosinthira kutentha pozungulira chosindidwa kuti chikwaniritse kusamutsa kutentha bwino. Kapangidwe kake kamakhala ndi thupi lozungulira chosinthira kutentha, shaft yozungulira, msonkhano wa chosindidwa, chipangizo choyendetsera ndi makina otsekera. Thupi la chosinthira kutentha nthawi zambiri limakhala ndi kapangidwe kawiri, ndipo chotenthetsera kapena choziziritsira chimadutsa pakati. Shaft yozungulira imakhala ndi zosindidwa zambiri, zomwe zili pafupi ndi khoma lamkati la silinda pansi pa mphamvu ya centrifugal ndipo nthawi zonse zimakanda pamwamba pa chosinthira kutentha ndi kuzungulira kwa shaft.

 Panthawi yogwira ntchito, zinthu zomwe ziyenera kukonzedwa zimalowa mu chosinthira kutentha kuchokera pamwamba ndipo zimatsika pansi pa khoma lamkati la silinda pansi pa mphamvu yokoka. Chotsukira chozungulira sichimangokhala chosakaniza, komanso chofunika kwambiri, chimasinthiratu filimuyo pamalo osamutsira kutentha kuti zinthuzo zisaphike kapena kukulira pamwamba pa kutentha kwakukulu. Njira yokonzanso filimuyi imalola zosinthira kutentha pamwamba zomwe zatsukidwa kuti zikwaniritse bwino kwambiri kusamutsa kutentha, nthawi zambiri mpaka katatu kapena kasanu kuposa zosinthira kutentha wamba.

 Gawo lofunika kwambiri la chosinthira kutentha cha pamwamba chokokedwa ndi makina okokedwa, omwe kapangidwe kake kamakhudza mwachindunji magwiridwe antchito a zida. Makina osinthira kutentha amakono okokedwa pamwamba nthawi zambiri amagwiritsa ntchito chokokedwa chosinthika, kudzera mu mphamvu ya kasupe kapena centrifugal kuti asinthe mphamvu yolumikizana pakati pa chokokedwa ndi khoma la silinda, osati kungowonetsetsa kuti chikokedwe bwino, komanso kupewa kuwonongeka kwambiri. Dongosolo lotsekera nalonso ndi gawo lofunikira, popewa kutayikira kwa zinthu, komanso kuonetsetsa kuti shaft yozungulira ikugwira ntchito bwino.

 

Chachiwiri, ubwino ndi zofooka za chosinthira kutentha pamwamba chofufutidwa

Ubwino waukulu wa chosinthira kutentha cha scraper ndi kuthekera kwake kugwira zinthu zokhuthala kwambiri komanso zosapsa kutentha. Pankhani yokonza chakudya, monga kupanga puff pastry margarine, chokoleti, jamu, tchizi ndi zinthu zina, chosinthira kutentha chachikhalidwe chimakhala chovuta kukwaniritsa zofunikira pa ndondomekoyi, ndipo chosinthira kutentha cha scraper chingathe kuthetsa mavutowa bwino kwambiri. Kuchuluka kwake kosinthira kutentha kumatha kufika 2000-5000W/(m²·K), kokwera kwambiri kuposa chosinthira kutentha cha chipolopolo ndi chubu wamba.

 

Pogwira ntchito ndi zinthu zosavuta kukulitsa, ubwino wa chosinthira kutentha cha scraper ndi woonekeratu. Mu makampani opanga mafuta, mafuta olemera, phula ndi zinthu zina zimakhala zosavuta kuphikidwa pamalo osamutsira kutentha panthawi yotenthetsera, ndipo zosinthira kutentha zachikhalidwe zimafunika nthawi yopuma pafupipafupi kuti ziyeretsedwe. Chosinthira kutentha cha scraper kudzera mu zotsatira zokanda mosalekeza, chimateteza bwino vutoli, ndipo chimawonjezera nthawi yogwira ntchito mosalekeza.

 

Komabe, zosinthira kutentha pamwamba zomwe zimakokedwa zilinso ndi zofooka zina. Choyamba ndi mtengo wokwera wa zida, chifukwa cha kapangidwe kake kovuta ka makina ndi zofunikira pakukonza molondola, ndalama zoyambira zimakhala zazikulu kwambiri kuposa zosinthira kutentha wamba. Kachiwiri, mtengo wokonza ndi wokwera, ndipo chokokera ndi chosindikizira ndi ziwalo zosatetezeka ndipo ziyenera kusinthidwa nthawi zonse. Kuphatikiza apo, pogwira ntchito ndi zinthu zokhuthala pang'ono, zabwino zake sizowonekera, koma zitha kuwonjezera kugwiritsa ntchito mphamvu chifukwa cha kusakaniza kwa makina.

 

Chachitatu, munda wogwiritsira ntchito ndi chitukuko chamtsogolo cha chosinthira kutentha pamwamba chofufutidwa

Mu makampani azakudya, zosinthira kutentha pamwamba zimagwiritsidwa ntchito kwambiri pakutenthetsa chokoleti, kuyeretsa jamu, kusakaniza batala ndi njira zina. Mwachitsanzo, popanga chokoleti, zinthuzo ziyenera kuyendetsedwa bwino mkati mwa kutentha kwina kuti ziwongolere kutentha, ndipo chosinthira kutentha cha scraper chingathe kuwongolera kutentha molondola komanso kusintha kutentha kofanana kuti zitsimikizire kuti zinthuzo ndi zabwino.

 

Mu mafakitale a mankhwala, zosinthira kutentha pamwamba zimagwiritsidwa ntchito makamaka popanga ma polima, kutentha mafuta ambiri ndi njira zina. Pakupanga ma polima, kukhuthala kwa zinthuzo kumasintha ndi njira yochitira zinthu, zomwe zimakhala zovuta kusintha kuti zigwirizane ndi chosinthira kutentha chachikhalidwe, koma chosinthira kutentha cha scraper nthawi zonse chimatha kusunga kutentha bwino. Pakuyeretsa mafuta, chosinthira kutentha cha scraper chimagwiritsidwa ntchito kutentha mafuta olemera, phula ndi zinthu zina, zomwe zimathetsa vuto la coking.

 

M'tsogolomu, chitukuko cha zosinthira kutentha pamwamba pa nthaka chidzakula motsatira nzeru, kugwira ntchito bwino kwambiri komanso ntchito zambiri. Ponena za nzeru, masensa ambiri ndi machitidwe owongolera adzaphatikizidwa kuti akwaniritse kuyang'anira nthawi yeniyeni komanso kusintha kwa magawo ogwirira ntchito. Kupanga sayansi ya zinthu kudzabweretsa zipangizo zatsopano zomwe sizingawonongeke komanso sizingawonongeke ndikuwonjezera moyo wa zida. Kuphatikiza apo, kapangidwe ka modular kadzakhala chizolowezi chothandizira kukonza ndi kukweza zida.

 

Monga mtundu wa zida zosinthira kutentha zogwira mtima, chosinthira kutentha cha scraper chimagwira ntchito yofunika kwambiri popanga mafakitale amakono. Chifukwa cha kupita patsogolo kosalekeza kwa ukadaulo, gawo logwiritsira ntchito lidzakulitsidwa kwambiri, ndipo magwiridwe antchito ake adzapitirirabe kukhala abwino. M'tsogolomu, chosinthira kutentha cha scraper chidzapereka chithandizo chachikulu pakusunga mphamvu ndi kuchepetsa utsi, kukonza magwiridwe antchito, ndikupereka chithandizo champhamvu pakukula kokhazikika kwa kupanga mafakitale.
