ʻO ka mīkini pellet kahi mea hana no ka hoʻopili ʻana i ka wahie pellet biomass a me ka meaʻai pellet, ma waena o ka roller pressure ka mea nui a me ka ʻāpana palupalu.Ma muli o kāna hana koʻikoʻi a me nā kūlana hana koʻikoʻi, ʻoiai me ke ʻano kiʻekiʻe, hiki ʻole ke ʻaʻahu a me ka waimaka.I ke kaʻina hana, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i nā rollers kaomi, no laila he mea koʻikoʻi ka mea hana a me ka hana ʻana o nā rollers kaomi.
Ka hoʻopololei ʻole ʻana o ka ʻōwili kaomi o ka mīkini ʻāpana
ʻO ke kaʻina hana o ka ʻōwili kaomi: ʻokiʻoki, forging, normalizing (annealing), rough machining, quenching and tempering, semi precision machining, surface quenching, and precision machining.Ua alakaʻi kekahi hui ʻoihana i ka noiʻi hoʻokolohua e pili ana i ka ʻaʻahu ʻana i nā wahie pellet biomass no ka hana ʻana a me ka hana ʻana, e hāʻawi ana i ke kumu kumu no ke koho kūpono o nā mea wili a me nā kaʻina hana wela.Eia nā hopena noiʻi a me nā manaʻo manaʻo:
Hōʻike ʻia nā niho a me nā ʻōpala ma ka ʻili o ka roller pressure o ka granulator.Ma muli o ka ʻaʻahu ʻana o nā haumia paʻakikī e like me ke one a me ka hoʻopili hao ma luna o ka ʻōwili kaomi, pili ia i ka ʻaʻahu maʻamau.ʻO ka ʻaʻahu maʻamau ma kahi o 3mm, a ʻokoʻa ka lole ma nā ʻaoʻao ʻelua.ʻO ka ʻaoʻao hānai he ʻaʻahu koʻikoʻi, me ke kapa o 4.2mm.Ma muli o ka ʻoiaʻiʻo ma hope o ka hānai ʻana, ʻaʻole i loaʻa i ka homogenizer ka manawa e hoʻohele like i ka mea a komo i ke kaʻina extrusion.
Hōʻike ka hōʻike ʻana i ka hemahema o ka lole microscopic ma muli o ka ʻaʻahu axial ma luna o ka ʻili o ka roller pressure i hoʻokumu ʻia e nā mea maka, ʻo ka nele o nā mea i luna o ka roller pressure ke kumu nui o ka hemahema.ʻO nāʻano nui o kaʻaʻahuʻana i kaʻaʻahu a me kaʻaʻahu abrasive, me ka morphology e like me nā lua paʻakikī, nā'ō'ō palau, nā'ō'ō palau, a me nā mea'ē aʻe, e hōʻike ana i nā silicates, nā'āpana one, nā mea hao, a me nā mea'ē aʻe i loko o nā mea maka heʻaʻahu koʻikoʻi ma ka ili o ka wili kaomi.Ma muli o ka hana ʻana o ka mahu wai a me nā kumu ʻē aʻe, ʻike ʻia nā ʻano like ʻole o ka lepo ma ka ʻili o ka ʻili kaomi, e hopena i nā māwae koʻikoʻi ma luna o ka ʻili o ka ʻili kaomi.
Manaʻo ʻia e hoʻohui i kahi kaʻina hoʻoneʻe haumia ma mua o ka ʻoki ʻana i nā mea maka no ka wehe ʻana i nā ʻāpana one, nā hoʻopili hao, a me nā mea haumia ʻē aʻe i hui pū ʻia i loko o nā mea maka, i mea e pale ai i ka ʻaʻahu a me nā waimaka ma luna o nā wili kaomi.E hoʻololi i ke ʻano a i ʻole ke kūlana hoʻokomo o ka mea ʻōpala e puʻunaue like i ka mea i loko o ke keʻena kaomi, e pale aku i ka ikaika ʻole ma luna o ka roller kaomi a me ka hoʻonui ʻana i ka ʻaʻahu ma luna o ka ʻili o ka pahu kaomi.Ma muli o ka hāʻule nui ʻana o ka roller pressure ma muli o ka ʻaʻahu o ka ʻili, i mea e hoʻomaikaʻi ai i kona paʻakikī o ka ʻili kiʻekiʻe, ke kūpaʻa ʻana, a me ka pale ʻana i ka corrosion, pono e koho ʻia nā mea ʻaʻahu a me nā kaʻina hana wela kūpono.
ʻO nā mea hana a me ka mālama ʻana i nā wili kaomi
ʻO ke ʻano mea a me ke kaʻina hana o ka roller pressure ka mea e pono ai no ka hoʻoholo ʻana i kona pale ʻana.ʻO nā mea wili maʻamau i hoʻohana ʻia me C50, 20CrMnTi, a me GCr15.Hoʻohana ke kaʻina hana i nā mea hana mīkini CNC, a hiki ke hoʻopili ʻia ka ʻili o ka roller me nā niho pololei, nā niho oblique, nā ʻano wili, a me nā mea e like me nā pono.Hoʻohana ʻia ʻo Carburization quenching a i ʻole kiʻekiʻe-frequency quenching heat treatment e hōʻemi i ka deformation roller.Ma hope o ka mālama ʻana i ka wela, hana hou ʻia ka mīkini pololei e hōʻoia i ka concentricity o nā pōʻai i loko a me waho, hiki ke hoʻolōʻihi i ke ola lawelawe o ka roller.
ʻO ke koʻikoʻi o ka hoʻomaʻamaʻa wela no nā wili kaomi
Pono e hoʻokō ka hana o ka roller pressure i nā koi o ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe (ʻaʻahu kūpaʻa), a me ka paʻakikī kiʻekiʻe, a me ka machinability maikaʻi (me ka polishing maikaʻi) a me ka pale ʻana i ka corrosion.He kaʻina hana koʻikoʻi ka mālama ʻana i ka wela o nā rollers i ka hoʻokuʻu ʻana i ka hiki o nā mea a hoʻomaikaʻi i kā lākou hana.He hopena pololei ia i ka pololei o ka hana ʻana, ka ikaika, ke ola lawelawe, a me nā kumukūʻai hana.
No nā mea like, ʻoi aku ka nui o ka ikaika, ka paʻakikī, a me ka lōʻihi o nā mea i loaʻa i ka overheating i ka hoʻohālikelike ʻana i nā mea i loaʻa ʻole i ka mālama wela.Inā ʻaʻole i kinai ʻia, e ʻoi aku ka pōkole o ke ola lawelawe o ka roller pressure.
Inā makemake ʻoe e hoʻokaʻawale i waena o nā ʻāpana i mālama ʻia i ka wela a me nā ʻāpana ʻaʻole wela i hana ʻia i ka mīkini pololei, ʻaʻole hiki ke hoʻokaʻawale iā lākou wale nō ma ka paʻakikī a me ka mālama ʻana i ka wela oxidation kala.Inā ʻaʻole ʻoe makemake e ʻoki a hoʻāʻo, hiki iā ʻoe ke hoʻāʻo e hoʻokaʻawale iā lākou ma ke kaomi ʻana i ke kani.ʻOkoʻa ke ʻano o ka metallographic a me ka friction o loko o nā castings a me nā mea hana i hoʻopaʻa ʻia a hoʻonāuki ʻia, a hiki ke ʻike ʻia e ka paʻi mālie.
Hoʻoholo ʻia ka paʻakikī o ka mālama ʻana i ka wela e nā kumu he nui, e like me ka pae waiwai, ka nui, ke kaumaha o ka mea hana, ke ʻano a me ke ʻano, a me nā ʻano hana hana.No ka laʻana, i ka wā e hoʻohana ai i ka uea puna e hana i nā ʻāpana nui, ma muli o ka mānoanoa maoli o ka mea hana, ʻōlelo ka manual e hiki i ka paʻakikī mālama wela ke hiki i 58-60HRC, ʻaʻole hiki ke hoʻokō i ka hui pū me nā mea hana maoli.Eia hou, hiki i nā hōʻailona paʻakikī kūpono ʻole, e like me ka paʻakikī kiʻekiʻe loa, hiki ke hopena i ka nalowale o ka paʻakikī o ka mea hana a hana i ka haki ʻana i ka wā hoʻohana.
ʻAʻole pono ka mālama ʻana i ka wela e hōʻoia i kahi waiwai paʻakikī kūpono, akā e hoʻolohe pū i kāna koho kaʻina a me ka mana kaʻina hana.Hiki ke hoʻokō i ka paʻakikī i koi ʻia ka overheated quenching a me tempering;Pēlā nō, ma lalo o ka hoʻomehana ʻana i ka wā quenching, hiki i ka hoʻoponopono ʻana i ka mahana wela ke hoʻokō i ka pae paʻakikī i koi ʻia.
Hana ʻia ka ʻōwili paʻi Baoke me ke kila kiʻekiʻe C50, e hōʻoiaʻiʻo ana i ka paʻakikī a me ke kūpaʻa ʻana o ka mīkini paʻi mīkini paʻi mai ke kumu.Hoʻohui ʻia me ka ʻenehana lapaʻau wela wela wela, hoʻonui nui i kona ola lawelawe.
