Munjira yobwezeretsanso zinyalala pamafakitale opanga mapepala, hydrapulper mosakayikira ndiye zida zoyambira. Imagwira ntchito yofunika kwambiri yakuphwanya zinyalala mapepala, matabwa a zamkati ndi zida zina kukhala zamkati, kuyala maziko a njira zopangira mapepala.
1. Gulu ndi Mapangidwe Apangidwe
(1) Kugaŵikana mwa Kuika Maganizo
- Low-consistency hydrapulper: Kugwira ntchito nthawi zambiri kumakhala kotsika, ndipo kapangidwe kake kamakhala kopangidwa ndi zinthu monga ma rotor, troughs, mipeni yapansi, ndi mbale zowonekera. Pali mitundu ya ma rotor monga ma rotor wamba a Voith ndi ma voith opulumutsa mphamvu. Mtundu wopulumutsa mphamvu ukhoza kupulumutsa mphamvu 20% mpaka 30% poyerekeza ndi mtundu wokhazikika, ndipo kapangidwe ka tsamba kamakhala kothandiza kwambiri kuti ziphatikizidwe ziziyenda. Nkhokwe nthawi zambiri imakhala yozungulira, ndipo ena amagwiritsa ntchito zida zowoneka ngati D. Mphepete mwa D-woboola pakati imapangitsa kuti zamkati ziziyenda movutikira, kusinthasintha kwa pulping kumatha kufika 4% mpaka 6%, mphamvu yopanga ndi yoposa 30% kuposa yamtundu wozungulira, ndipo ili ndi malo ang'onoang'ono pansi, mphamvu zochepa komanso ndalama zogulira. Mpeni wapansi nthawi zambiri umatha kuchotsedwa, wopangidwa ndi chitsulo champhamvu kwambiri, ndipo m'mphepete mwake muli zinthu zosagwira ntchito monga NiCr chitsulo. Kukula kwa mabowo owonekera pazenera ndi ochepa, nthawi zambiri 10-14mm. Ngati imagwiritsidwa ntchito kuswa matabwa a zamkati zamalonda, mabowo a skrini ndi ang'onoang'ono, kuyambira 8-12mm, zomwe zimathandizira pakulekanitsa zonyansa zazikuluzikulu.
- High-consistency hydrapulper: Kugwirizana kogwira ntchito ndi 10% - 15% kapena kupitilira apo. Mwachitsanzo, rotor yokhazikika kwambiri imatha kupangitsa kuti zamkati ziphwanyike mpaka 18%. Pali turbine rotors, mkulu-kusasinthasintha rotor, etc. The cholumikizira chozungulira akhoza kufika zamkati kuswa kusasinthasintha 10%. Rotor yokhazikika kwambiri imawonjezera malo olumikizana ndi zamkati ndikuzindikira kusweka pogwiritsa ntchito kumeta pakati pa ulusi. Kapangidwe ka khola ndi kofanana ndi kamene kamakhala kocheperako, ndipo chimbudzi chokhala ngati D chimatengedwanso pang'onopang'ono, ndipo njira yogwirira ntchito nthawi zambiri imakhala yapakatikati. Mabowo owonekera pazenera ndi okulirapo, nthawi zambiri 12-18mm, ndipo malo otseguka ndi 1.8-2 kuchulukitsa kwa gawo labwino la zamkati.
(2) Gulu ndi Mapangidwe ndi Njira Yogwirira Ntchito
- Malinga ndi kapangidwe kake, imatha kugawidwa m'mitundu yopingasa komanso yowongoka; molingana ndi momwe amagwirira ntchito, imatha kugawidwa m'mitundu yopitilira komanso yapakatikati. The ofukula mosalekeza hydrapulper akhoza mosalekeza kuchotsa zonyansa, ndi mkulu zida magwiritsidwe, mphamvu yaikulu kupanga ndi ndalama zochepa; hydrapulper yokhazikika imakhala ndi digiri yokhazikika, koma imakhala ndi mphamvu zambiri zogwiritsira ntchito mphamvu ndipo mphamvu yake yopanga imakhudzidwa ndi nthawi yosasweka; chopingasa cha hydrapulper sichimakhudzana kwambiri ndi zonyansa zolemera komanso kuvala pang'ono, koma mphamvu yake yogwirira ntchito nthawi zambiri imakhala yaying'ono.
2. Mfundo Yogwira Ntchito ndi Ntchito
The hydrapulper amayendetsa zamkati kuti apange chipwirikiti champhamvu ndi mphamvu yometa makina pogwiritsa ntchito kuzungulira kothamanga kwa rotor, kotero kuti zopangira monga mapepala otayirira zimang'ambika ndikubalalika mu zamkati. Panthawi imodzimodziyo, mothandizidwa ndi zigawo monga mapepala a skrini ndi zipangizo za 绞绳 (zingwe za zingwe), kulekanitsa koyambirira kwa zamkati ndi zonyansa kumatheka, kumapanga mikhalidwe yotsatiridwa ndi kuyeretsedwa kotsatira. Pulper yotsika kwambiri imayang'ana kwambiri pakusweka kwamakina ndi kuchotsa zonyansa koyamba, pomwe pulper yapamwamba kwambiri imamaliza kusweka bwino pansi pa kusinthasintha kwakukulu kudzera muvuto lamphamvu la hydraulic ndi kukangana pakati pa ulusi. Ndiwoyenera makamaka kupanga mizere yomwe imafunikira kuyika, yomwe ingapangitse inki kukhala yosavuta kupatukana ndi ulusi, ndipo imakhala ndi zotsatira zabwino zochotsa pa zinthu zosungunuka zomwe zimasungunuka kuposa ma pulpers wamba otsika.
3. Kugwiritsa Ntchito ndi Kufunika
Ma Hydrapulpers amagwiritsidwa ntchito kwambiri pamizere yopangira zinyalala ndipo ndi zida zofunika kwambiri pozindikira kugwiritsa ntchito zinyalala zamapepala. Kugwira ntchito kwawo moyenera sikungangowonjezera kuchuluka kwa mapepala otayira, kuchepetsa mtengo wa zinthu zopangira mapepala, komanso kuchepetsa kudalira nkhuni yaiwisi, yomwe ikugwirizana ndi chitukuko cha kusunga mphamvu ndi kuteteza chilengedwe. Mitundu yosiyanasiyana ya ma hydrapulpers imatha kusankhidwa mosinthika malinga ndi zosowa zopanga. Mwachitsanzo, ofukula mosalekeza mtundu akhoza kusankhidwa pokonza zinyalala pepala ndi kuchuluka kwa zonyansa, ndi mkulu-kusasinthasintha mtundu akhoza kusankhidwa amafuna mkulu kuswa kusasinthasintha ndi deinking zotsatira, kuti azisewera bwino mu zochitika zosiyanasiyana kupanga ndi kulimbikitsa chitukuko chokhazikika cha makampani papermaking.
