-kulowetsa fyuluta
Musanalowe muzinthu zenizeni zazosefera pampu vacuum, tiye tikambirane kaye kuti pampu ya vacuum ndi chiyani. Pampu ya vacuum ndi chipangizo chomwe chimapanga ndikusunga mpweya mkati mwa dongosolo lotsekedwa. Amachotsa mamolekyu a gasi kuchokera ku voliyumu yosindikizidwa kuti apange malo otsika kwambiri. Mapampu a vacuum amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, monga kupanga, mankhwala, kukonza chakudya, komanso m'malo ofufuza zasayansi.
Zosefera zolowetsa ndi gawo lofunikira papampu ya vacuum, yomwe ili ndi udindo wochotsa zonyansa ndi zinyalala mumpweya wa mpope. Amagwira ntchito yofunika kwambiri kuti pampu ya vacuum ikhale yogwira ntchito komanso moyo wautali, komanso kuonetsetsa kuti chinthu chomaliza kapena njira yomwe imadalira vacuum imadalira.
Mpweya wolowetsa wapampu yotsekemera nthawi zambiri umakhala ndi zonyansa zosiyanasiyana, monga fumbi, tinthu tating'onoting'ono, chinyezi, ngakhale mpweya. Ngati zonyansazi sizichotsedwa mumlengalenga, zimatha kuwononga kwambiri pampu ya vacuum ndikusokoneza magwiridwe antchito ake. Apa ndipamene zosefera za vacuum pampu zimagwira ntchito.Zosefera zolowetsa zimagwira ntchito ngati chotchinga pakati pa doko lolowera ndi mpope wokha. Imagwira ndi misampha zoipitsa, kuzilepheretsa kulowa mpope ndikuwononga. Zosefera nthawi zambiri zimakhala ndi porous zinthu zomwe zimalola kuti mpweya udutse potsekera tinthu tating'onoting'ono ndi zinyalala. Zosefera zitha kusiyanasiyana kutengera ntchito yeniyeni komanso mtundu wa zonyansa zomwe zichotsedwe.
Pali mitundu ingapo ya zosefera zapampu za vacuum zomwe zikupezeka pamsika, kuphatikiza zosefera, zosefera zolumikizirana, ndi zosefera mamolekyulu. Zosefera zazing'ono zimapangidwa kuti zizigwira tinthu tolimba, monga fumbi ndi dothi, ndikulola kuti mpweya udutse. Zosefera zophatikizira zimatha kutenga ma aerosols amadzimadzi, monga nkhungu yamafuta ndi chinyezi, pophatikiza madontho ang'onoang'ono kukhala akuluakulu, kuwapangitsa kukhala osavuta kutchera ndikuchotsa. Koma zosefera za mamolekyulu, zimatha kuchotsa mpweya kapena mankhwala enaake mumpweya umene umalowa m'mlengalenga pogwiritsa ntchito ma adsorption kapena ma chemical reaction.
Kuchita bwino ndi magwiridwe antchito a pampu ya vacuum zimatengera kapangidwe kake, zosefera zomwe zimagwiritsidwa ntchito, komanso mphamvu yake yosunga zonyansa. Kusamalira nthawi zonse ndikusintha fyuluta ndikofunikira kuti zitsimikizire kuti zimagwira ntchito bwino. M'kupita kwa nthawi, fyulutayo imakhala yodzaza ndi zonyansa, kuchepetsa mphamvu zake ndikuwonjezera ntchito papampu ya vacuum. Choncho, ndikofunika kuyang'anitsitsa ndikusintha fyuluta monga momwe wopanga akulimbikitsira.
Sikuti zosefera zolowetsa zimateteza mpope wokha, komanso zimalepheretsa kuipitsidwa kwa njirayo kapena chinthu chomaliza chomwe chimadalira vacuum. Mwachitsanzo, popanga mankhwala, pampu ya vacuum imagwiritsidwa ntchito nthawi zambiri kupanga malo osabala. Zosefera zimatsimikizira kuti palibe zonyansa zomwe zimalowa m'thupi, kusunga chiyero ndi khalidwe lake.
Pomaliza,zosefera zolowetsandi zigawo zofunika kwambiri za vacuum pump system. Amachotsa zonyansa ndi zinyalala kuchokera ku mpweya wolowa, kuteteza mpope kuti zisawonongeke ndikusunga bwino. Pogwiritsa ntchito fyuluta yoyenera yogwiritsira ntchito, mafakitale amatha kuonetsetsa kuti njira zawo ndi zomaliza zimakhala zabwino komanso zoyera. Kusamalira nthawi zonse ndikusintha fyuluta ndikofunikira kuti pampu ya vacuum igwire bwino ntchito yake.
