Mu njira yogwiritsira ntchito mapepala otayira zinyalala m'makampani opanga mapepala, cholekanitsa ulusi ndi chida chofunikira kwambiri kuti chichotse ulusi bwino pa mapepala otayira zinyalala ndikuwonetsetsa kuti mapepalawo ndi abwino. Choyikamo chotsukidwa ndi choyikamo cha hydraulic chimakhala ndi mapepala ang'onoang'ono osabalalika. Ngati zida zodulira zachikhalidwe zimagwiritsidwa ntchito kuchotsa ulusi papepala lotayira zinyalala, sikuti mphamvu yokha ndi yokwera ndipo kuchuluka kwa zida zogwiritsira ntchito kumakhala kochepa, komanso mphamvu ya pulp idzachepa chifukwa chodulanso ulusi. Cholekanitsa ulusi chimatha kufalitsa ulusi wonse popanda kuwadula, ndipo chakhala chida chogwiritsidwa ntchito kwambiri pochotsa ulusi papepala lotayira zinyalala pakadali pano.

Kugawa kwa Olekanitsa Ulusi

Malinga ndi kusiyana kwa kapangidwe ndi ntchito, olekanitsa ulusi amagawidwa m'magulu awiri:olekanitsa ulusi wa zotsatira imodzindiolekanitsa ulusi wophatikizika.

Cholekanitsa Ulusi Chokha: Kapangidwe Kabwino, Ntchito Yomveka Bwino

Cholekanitsa ulusi wa single-effect chili ndi kapangidwe kabwino kwambiri (monga momwe zasonyezedwera pachithunzi chogwirira ntchito cha Chithunzi 5-17). Mfundo yake yogwirira ntchito ndi iyi: pulp imapopedwa kumapeto ang'onoang'ono a chipolopolo chozungulira kuchokera pamwamba motsatira njira yolunjika. Pamene impeller ikuzungulira, masambawo alinso ndi ntchito yopopera, zomwe zimapangitsa kuti pulp ipange kuyenda kwa axial ndi kuyenda kwamphamvu kwamphamvu. Pakati pa mkombero wa impeller ndi mpeni wapansi, komanso pakati pa impeller ndi mbale yotchingira, pulp imachotsedwa ulusi ndikulekanitsidwa kukhala ulusi.

• Kulekanitsa Kwabwino kwa Zamkati: Mpeni wolekanitsa pansi womwe uli m'mphepete mwa impeller sikuti umangolimbikitsa kulekanitsa ulusi, komanso umapanga kugwedezeka kuti ufufuze mabowo otchingira, ndipo zamkati zabwino zimatumizidwa kuchokera m'mabowo otchingira kumbuyo kwa impeller.
• Kuchotsa Zonyansa: Zonyansa zopepuka monga mafilimu apulasitiki zimakhazikika pa mzere chifukwa cha mphamvu ya eddy current, ndipo zimatulutsidwa nthawi zonse kuchokera pakati pa chivundikiro chakutsogolo pamodzi ndi gawo laling'ono la pulp yosakanikirana; zonyansa zolemera zimayikidwa mu mphamvu ya centrifugal ndikulowa mu doko lotulutsa slag pansi pa mapeto akuluakulu motsatira mzere wamkati wa khoma kuti zitulutsidwe.

Ponena za kayendetsedwe ka ntchito, nthawi yotsegulira valavu yotulutsa mpweya woipa iyenera kusinthidwa malinga ndi kuchuluka kwa mpweya woipa womwe uli mu ulusi wa pepala lotayira. Kawirikawiri, mpweya woipa woipa umatuluka kamodzi pa mphindi 10-40 zilizonse, nthawi iliyonse kwa masekondi 2-5; mpweya woipa wolemera umatuluka kamodzi pa maola 2 aliwonse. Kudzera mu njira yowongolera mpweya woipa, imatha kusiyanitsa ulusi wonse ndikupewa kuswa mpweya woipa monga mapulasitiki, ndikubwezeretsa mwachangu kugawa bwino, potsiriza kuzindikira kulekanitsa ndi kuyeretsa ulusi.

Ndi kapangidwe kake kapadera komanso njira yogwirira ntchito, cholekanitsa ulusi chikuwonetsa zabwino zazikulu mu njira yochotsera ulusi wa mapepala otayidwa. Sikuti chimangothetsa mavuto a zida zodulira wamba, komanso chimamaliza bwino ntchito zogawa ulusi ndi kulekanitsa zodetsa, ndikuyika maziko olimba owongolera mtundu wa mapepala otayidwa ndikuwonetsetsa kuti kupanga mapepala kukuyenda bwino. Ndi chimodzi mwa zida zofunika kwambiri pakugwiritsa ntchito mapepala otayidwa m'makampani amakono opanga mapepala.
