Chidule cha akuluakulu
Ogwira ntchito m'mafakitale odyetsera omwe amagwiritsa ntchito mizere ya matani ambiri pa ola limodzi nthawi zambiri amakumana ndi vuto lodziwika bwino: mphero ya pellet imakhala malo oletsa kugwedezeka. Zinthu zopangira zimayenda bwino pogaya ndi kusakaniza, koma gawo la pellet nthawi zonse silikwanira mphamvu ya dzina. Vutoli limawononga malire, limachedwetsa kutumiza, komanso limakakamiza nthawi yochulukirapo. Nkhani yabwino ndi yakuti zifukwa zambiri zimabwerera m'mbuyo ku zinthu zingapo zamakina ndi njira - zomwe sizimafuna kusintha makina onse. Nkhaniyi ikufotokoza za malo omwe anthu ambiri amalephera komanso mayankho omwe mafakitale opita patsogolo agwiritsa ntchito kuti abwezeretse kufalikira kwa pellet mogwirizana ndi kufunikira kwa zinthu zomwe zatsala.
1. Mtengo Weniweni wa Nthawi Yopuma ya Pellet Mill
Mphero ya pellet yomwe imayesedwa pa 15 t/h yomwe nthawi zonse imapereka 12 t/h imataya pafupifupiMatani 600 a zinthu zomwe zingatheke kupangidwa pamwezi— kumasulira kukhala kutayika kwa ndalama pachaka kwa ziwerengero zisanu ndi chimodzi.
Komabe mphero zambiri zimaona kusagwira bwino ntchito kwa nthawi yayitali ngati "momwe zimayendera." Manambalawa akusonyeza zosiyana. Ogwira ntchito omwe amathetsa mavuto mwanzeru nthawi zambiri amachira.85–95% ya mphamvu zomwe zapezeka mkati mwa masabata awiri— osati pogula zida zatsopano, koma pokonza zomwe zili kale pansi.
2. Kuvala kwa Ring Die: Chotupa Chosawoneka
Mkhalidwe wa mphete ndiye chinthu chofunikira kwambiri pakupanga ma pellet mill. Die yokhala ndi ma hole inlets osweka, ma compression ratios osafanana, kapena ma bell-mouthed exits amakakamiza injini kugwira ntchito molimbika pa tani iliyonse ya kutulutsa. Zizindikiro zake n'zosatsutsika:
Vuto lalikulu nthawi zambiri silimakhala ndi die yokha. Ma die ambiri amakono amagwiritsa ntchito zitsulo zokhala ndi chromium alloy yokhala ndi kulimba mu60–62 HRC— yokwanira pakupanga zinthu mwachizolowezi. Vuto lili mu relief taper ndi hole entry geometry. Izi zikawonongeka, effective compression ratio imasinthasintha, ndipo zinthuzo sizimayendanso pamlingo wopangidwa.
Mafakitale ena amathetsa vutoli mwa kungosintha ma die pa kalendala yokhazikika. Njira yolondola kwambiri imaphatikizapo kutsatira momwe mphamvu imagwiritsidwira ntchito (kWh/t) pa die iliyonse ndikukoka die pamene muyesowo ukukwera.10–12% kuposa momwe zinalili kaleChoyambitsa ichi chogwiritsa ntchito deta chimapewa kusintha zinthu msanga pamene chikuwonongeka chisanagwere mavuto ena.
3. Kukonza Mpweya: Ubwino Woposa Kuchuluka
Kukonza nthunzi kumakambidwa kwambiri koma sikumveka bwino. Cholinga si kuwonjezera nthunzi yochuluka momwe zingathere - koma ndi kupeza chinyezi chofanana ndi kutentha pa tinthu tonse tomwe timalowa mu die. Kukonza nthunzi kukalephera, kusakaniza kwa starch sikukwanira, kumangirira kumakhala kofooka, ndipo die iyenera kulipira mphamvu ya makina.
Zosintha zitatu zomwe ndizofunikira kwambiri:
Mipiringidzo yomwe yasinthidwa kukhalama valve a nthunzi osinthidwa okhala ndi malamulo oyendetsera kuthamanga kwa PID— ndi kukula kwa zipinda zosungiramo mankhwala mpaka masekondi 45-60 kuti zikhale zovuta — nthawi zonse zimanenaKupindula kwa ntchito yogwira ntchito kwa 10–18%pa die ndi mota yomweyo.
4. Kusintha kwa Roller ndi Die-Roller Gap
Kusiyana pakati pa ma rollers ndi nkhope ya die kumakhudza mphamvu yamagetsi kuposa momwe ogwiritsa ntchito ambiri amaganizira. Ndi yayikulu kwambiri, ndipo gawo la zinthu silingathe kupanga kukangana kokwanira kuti likokedwe m'mabowo. Ndi yopapatiza kwambiri, ndipo kukhudzana ndi chitsulo ndi chitsulo kumathandizira kuwonongeka ndikuwonjezera mphamvu yokoka.
| Mtundu wa Mapangidwe | Kukula kwa Pogaya | Mpata Wovomerezeka |
|---|---|---|
| Chakudya Chachizolowezi cha Nkhuku | 350–400 maikuloni | 0.3–0.5 mm |
| Ma Concentrates Olemera a Ruminant | Zimasiyana | 0.5–0.7 mm |
Chiwerengero chenicheni sichinthu chofunikira kwambiri kuposakusinthasintha kwa ma rollers onse atatuChosindikizira chokhala ndi chozungulira chimodzi pa 0.3 mm ndi china pa 0.7 mm chimagwira ntchito bwino pa masilinda awiri, zomwe zimawononga mphamvu ya injini ndikupanga mawonekedwe osafanana a ma die wear.
Njira Yabwino Kwambiri:Kutsimikizira kusiyana kwa mlungu uliwonse pogwiritsa ntchito chida choyezera - ndi kukonza mwachangu - ndi imodzi mwa njira zochepetsera mtengo komanso zobweza zambiri zomwe zimapezeka ku fakitale iliyonse yodyetsera ziweto.
5. Kugwiritsa Ntchito Bwino Sitima Pagalimoto ndi Pagalimoto
Pamene zosintha zonse zamakina ndi njira zakonzedwa bwino ndipo mphamvu yamagetsi ikadali kuchedwa, chidwi chimatembenukira ku dongosolo la drive.
Taya3–6% ya mphamvu ya injinikutsetsereka ndi kutayika kwa makina pamene malamba akukalamba ndi kupsinjika kumachepa.
Ma profiles a pinion-tooth osweka amatha kutayaperesenti yofananaasanayambe kumveka bwino.
Kusanthula kugwedezeka ndi kuyang'ana kwa kutentha kwa zigawo za drive kumapereka chenjezo koyambirira. Mu nkhani ina yolembedwa, mphero ikuyenda pa88% ya zotsatira zomwe zapezeka pa miyezi isanu ndi umodziAmangofunika kusintha malamba ake a V ndikumangiriridwa bwino - ntchito ya maola awiri yomwe idabwezeretsa mphamvu zonse.
6. Kupanga Zisankho Zauinjiniya ndi Deta
Kusiyana pakati pa mphero yomwe imagwira ntchito molakwika nthawi zonse ndi yomwe imagwira ntchito molingana ndi kapangidwe kake nthawi zambiri kumadaliranjira yoyezera. Ziyeso zofunika kwambiri pa kulemba pa kusintha kulikonse:
Popanda deta iyi, vuto lililonse limawoneka ngati "makina akukalamba." Ndi izi, mavuto enieni komanso otheka kuthetsedwa amabuka - condenser yomwe ikutha, chogwirira chozungulira chowonongeka, msampha wa nthunzi womwe watsekeredwa - ndipo chilichonse chingathe kuthetsedwa ndi kukonza kolunjika m'malo mopempha ndalama zambiri.
Malingaliro Omaliza
Mavuto a mphero ya pellet nthawi zambiri samachitika chifukwa cha kulephera kwakukulu kamodzi. Amasonkhana pang'onopang'ono - kufa kupitirira malire ake abwino, kusuntha kwa nthunzi, mipata yozungulira ikusiyana, malamba oyendetsera akutambasuka.
Chinthu chilichonse chokha chingawononge ndalama2–3% ya kuchuluka kwa zinthu zomwe zagwiritsidwa ntchitoPogwirizana, amatha kukoka mzere15–20% pansi pa cholinga chomwe mukufuna.
Yankho lake si lachinsinsi: kuyeza mwadongosolo, ntchito yanthawi yake, ndi zisankho zaukadaulo zomwe zimachokera ku deta osati chizolowezi. Makampani omwe amagwiritsa ntchito njira imeneyi nthawi zonse amapeza zotsatira zabwino.mkati mwa 5% ya dzina la plate— ndipo nthawi zambiri amapitirira.
