Mu njira yobwezeretsanso mapepala otayidwa m'makampani opanga mapepala, hydrapulper mosakayikira ndiye chida chachikulu. Imagwira ntchito yofunika kwambiri yoswa mapepala otayidwa, matabwa a pulp ndi zinthu zina zopangira kukhala pulp, ndikuyika maziko a njira zina zopangira mapepala.
1. Kugawa ndi Kukonza Kapangidwe ka Kapangidwe
(1) Kugawa m'magulu malinga ndi kukhazikika
- Hydrapulper yosasinthasintha: Kugwira ntchito kwake nthawi zambiri kumakhala kochepa, ndipo kapangidwe kake kamakhala ndi zinthu monga ma rotor, ma thorough, mipeni ya pansi, ndi ma screen plate. Pali mitundu ya ma rotor monga ma Voith rotor wamba ndi ma Voith rotor osunga mphamvu. Mtundu wosunga mphamvu umatha kusunga mphamvu 20% mpaka 30% poyerekeza ndi mtundu wamba, ndipo kapangidwe ka tsamba kamakhala kothandiza kwambiri kuti ma pulp ayende bwino. Ma thorough ambiri amakhala ozungulira, ndipo ena amagwiritsa ntchito ma D-shaped tubers atsopano. Ma D-shaped tube amapangitsa kuti ma pulp ayende bwino, ma pulping consistency amatha kufika 4% mpaka 6%, mphamvu yopangira ndi yoposa 30% kuposa ya mtundu wa round through, 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 mwa tsamba muli zinthu zosatha monga chitsulo cha NiCr. M'mimba mwake mwa mabowo a screen plate ndi ang'onoang'ono, nthawi zambiri 10-14mm. Ngati ikugwiritsidwa ntchito kuswa ma pulp board amalonda, mabowo otchingira amakhala ang'onoang'ono, kuyambira 8-12mm, zomwe zimathandiza poyambitsa kulekanitsa zinyalala zazikulu.
- Hydrapulper yokhazikika kwambiri: Kukhazikika kwa ntchito ndi 10% - 15% kapena kupitirira apo. Mwachitsanzo, rotor yokhazikika kwambiri ingapangitse kuti kusinthasintha kwa pulp kukhale kokwera mpaka 18%. Pali ma rotor a turbine, ma rotor okhazikika kwambiri, ndi zina zotero. Rotor ya turbine imatha kufika pa kusinthasintha kwa pulp kwa 10%. Rotor yokhazikika kwambiri imawonjezera malo olumikizirana ndi pulp ndipo imasweka pogwiritsa ntchito njira yodula pakati pa ulusi. Kapangidwe ka through ndi kofanana ndi ka through yokhazikika pang'onopang'ono, ndipo through yooneka ngati D imatengedwanso pang'onopang'ono, ndipo njira yogwirira ntchito nthawi zambiri imakhala yocheperako. M'mimba mwake mwa mabowo otchingira a plate yotchingira ndi yayikulu, nthawi zambiri 12-18mm, ndipo malo otseguka ndi 1.8-2 kuposa gawo labwino la pulp outlet.
(2) Kugawa Magulu ndi Kapangidwe ndi Njira Yogwirira Ntchito
- Malinga ndi kapangidwe kake, ikhoza kugawidwa m'mitundu yopingasa ndi yoyima; malinga ndi momwe imagwirira ntchito, ikhoza kugawidwa m'mitundu yopitilira ndi yosinthasintha. Hydrapulper yopingasa yoyima imatha kuchotsa zonyansa nthawi zonse, pogwiritsa ntchito zida zambiri, kupanga kwakukulu komanso ndalama zochepa; Hydrapulper yopingasa yoyima imakhala ndi digiri yokhazikika yosweka, koma imagwiritsa ntchito mphamvu zambiri ndipo mphamvu yake yopangira imakhudzidwa ndi nthawi yosasweka; Hydrapulper yopingasa imakhala ndi kukhudzana kochepa ndi zonyansa zambiri komanso kuwonongeka kochepa, koma mphamvu yake yogwirira ntchito nthawi zambiri imakhala yochepa.
2. Mfundo Yogwirira Ntchito ndi Ntchito
Hydrapulper imayendetsa pulp kuti ipange kugwedezeka kwamphamvu ndi mphamvu yoduladula makina kudzera mu kuzungulira kwachangu kwa rotor, kotero kuti zinthu zopangira monga mapepala otayira zimang'ambika ndikufalikira mu pulp. Nthawi yomweyo, mothandizidwa ndi zinthu monga ma screen plates ndi zida za 绞绳 (ma rope reels), kulekanitsidwa koyamba kwa pulp ndi zonyansa kumachitika, zomwe zimapangitsa kuti pakhale njira zoyeretsera ndi kuwunikira pambuyo pake. Pulper yotsika imayang'ana kwambiri pakusweka kwa makina ndi kuchotsa zodetsa koyamba, pomwe pulper yokhazikika imamaliza kusweka bwino pansi pa kusinthasintha kwakukulu kudzera mu kugwedezeka kwamphamvu kwa hydraulic ndi kukangana pakati pa ulusi. Ndi yoyenera makamaka pamizere yopanga yomwe imafuna kuchotsedwa, zomwe zingapangitse kuti inki ikhale yosavuta kulekanitsidwa ndi ulusi, ndipo imakhala ndi zotsatira zabwino zochotsa zinthu zotentha kuposa ma pulper wamba otsika.
3. Kugwiritsa Ntchito ndi Kufunika Kwake
Ma Hydrapulpers amagwiritsidwa ntchito kwambiri popanga mapepala otayira zinyalala ndipo ndi zida zofunika kwambiri pakugwiritsira ntchito zinthu zotayira mapepala. Kugwira ntchito kwawo bwino sikungowonjezera kuchuluka kwa mapepala otayira, kuchepetsa mtengo wopanga zinthu zopangira mapepala, komanso kuchepetsa kudalira matabwa osaphika, zomwe zikugwirizana ndi chitukuko cha kusunga mphamvu ndi kuteteza chilengedwe. Mitundu yosiyanasiyana ya ma hydrapulpers imatha kusankhidwa mosavuta malinga ndi zosowa zopangira. Mwachitsanzo, mtundu wokhazikika woyimirira ukhoza kusankhidwa kuti ugwiritsidwe ntchito pokonza mapepala otayira okhala ndi zinyalala zambiri, ndipo mtundu wokhazikika kwambiri ungasankhidwe kuti ukhale wogwirizana kwambiri komanso wochotsa zinyalala, kuti ugwire bwino ntchito m'njira zosiyanasiyana zopangira ndikulimbikitsa chitukuko chokhazikika cha makampani opanga mapepala.
