Intermeshing Conical Twin Screw

ʻO Nanhaiya screw ka mea hana mua loa o Kina i ka hana ʻana i ka intermeshing conical twin screw. Me nā makahiki he ʻumi o ka ʻike i nā mīkini plastic, hoʻohana mākou i nā kaʻina hana kiʻekiʻe a me nā mea hana e hoʻolālā a hana i kahi ākea o nā ʻano screw. Hāʻawi kā mākou huahana i nā kumukūʻai hoʻokūkū a uhi i kahi ākea o nā mākeke ʻEulopa a me ʻAmelika. Manaʻo mākou i ka lilo ʻana i hoa pili lōʻihi ma Kina.

Hoʻolauna Huahana

Hana ʻia kēia māhoe conical intermeshing mai ke kila 38CrMoAla. He mea koʻikoʻi ka waiwai maka i ka hana ʻana, a koho mākou i ke kila ikaika a paʻa i ka ʻaʻahu mai nā mea hana kila Kina kaulana i kū i nā kūlana aupuni (GB/T 3077).

Hoʻohana mākou i ke kaʻina hana ʻōwili. Hoʻokumu kēia kaʻina hana i kahi kikoʻī kikoʻī ʻoi aku ka ikaika, e pale ana i ka haki ʻana. Hoʻoponopono pū ia i ka hewa pitch pitch i ≤0.1mm, e hōʻoia i ka hoʻopili like ʻana a me ka hoʻēmi ʻana i ka wehe ʻana.

Ua loaʻa iā Nanhaiya i nā ʻano R&D a me ka hoʻomaikaʻi ʻana a ua hoʻohui ʻia i loko o nā laina hana o nā mea hana like ʻole, e hoʻokō ana i ka hana kiʻekiʻe. Hāʻawi mākou i kahi palapala hōʻoia 1-2 makahiki, e pili ana i ka ratio hoʻohui mea kikoʻī. Hana ʻia nā barela o Nanhaiya i kahi kaʻina hana nitriding, me kahi ʻāpana 2mm mānoanoa o ka nickel-tungsten alloy spray-welded ma nā wahi i hoʻopaʻa ʻia. Hoʻonui kēia i ka paʻakikī o ka pahu mai HRC55-60 a ʻoi aku ma luna o HRC65, e hoʻonui ana i ka pale ʻana i ka lole e 2-4 mau manawa.

Nā kikoʻī o ka māhoe conical screw a me ka pahu

Hiʻona a me ka noi

1. Mea Hoʻolaha Mea: Paʻa a Paʻa, ʻAʻohe Backflow

Hoʻokumu ke ʻano intermeshing i kahi "keʻena waiwai" i hoʻopaʻa ʻia e koi ikaika i ka mea, e hoʻopau loa i ka pilikia backflow e pili ana me nā wili haʻahaʻa a i ʻole nā ​​​​meshing.

ʻO ka lawe ʻana i ka maikaʻi ʻaʻole i hoʻopilikia nui ʻia e ka viscosity mea. ʻOiai i ka lawelawe ʻana i nā mea viscous e like me nā plastic i hoʻoheheʻe ʻia a me nā slurries koʻikoʻi loa, hiki ke mālama ʻia kahi helu hānai paʻa, e hōʻoia i ka hana mau.

2. Ka hui 'ana a me ka 'ako 'ana: Ka hopena ikaika, 'ano like 'ole

Ke hoʻokuʻi ʻia nā wili ʻelua, hoʻokō lākou i ka hana ʻekolu o ka "ʻako," "knea," a me ka "huhū" ma luna o ka mea, e wāwahi koke i nā mea agglomerates a loaʻa ka microscopically like ʻole o ka hui ʻana o nā mea.

ʻO kēia hiki ke ako ikaika ke kōkua i ka hoʻoheheʻe ʻana a i ʻole ka hopena. No ka laʻana, i loko o ka plastic extrusion, hiki iā ia ke hoʻopōkole i ka manawa hoʻoheheʻe a hoʻokō i ka maikaʻi hoʻoheheʻe like ʻole.

3. Paʻi a me ka Mahana: Hiki ke hoʻomaluʻia, kūpono no ka hana kiʻekiʻe

Hoʻokumu a mālama pono ke keʻena paʻa i ke kaomi hana paʻa, kūpono ia no nā kaʻina hana e koi ana i ke kaomi, e like me ke kaomi ʻana i ka nui o ka paipu plastik extrusion a me nā hopena kaomi o nā mea reactive. ʻO ka manawa noho o ka mea i loko o ke keʻena paʻa he ʻano kūlike, a ʻoi aku ka like o ka hoʻololi ʻana o ka wela ma waena o ka wili a me ka barela, e hiki ai ke hoʻomalu pono i ka wela o nā mea a me ka pale ʻana i ka wela nui a i ʻole ka wela wela e hiki ke alakaʻi i ka pōʻino.

4. Ka laulā o ka noi: ʻO nā mea i koho ʻia no nā pono hana paʻakikī

He mea kūpono kēia no nā mea me ka viscosity kiʻekiʻe, ka elasticity kiʻekiʻe, a me ka pono o ka hui ʻana, e like me nā plastics, rubber, adhesives, a me nā uhi kiʻekiʻe.

Ke hoʻohālikelike ʻia me nā wili ʻē aʻe, ʻo Nanhaiya's intermeshing conical twin-screws e hōʻemi i ke koena o nā mea i loko o nā mea hana, e hoʻomaʻemaʻe i ka hoʻomaʻemaʻe ʻana i ka wā e hoʻololi ai i nā mea a me ka hoʻomaikaʻi ʻole ʻana i ka pono hana.

 ʻO nā wahi noi mua o ka intermeshing conical twin-screw extruders e uhi kokoke i nā hana koʻikoʻi o ke kaʻina hana plastics, mai nā mea maka a i nā huahana i hoʻopau ʻia.

1. Plastic Extrusion: Hoʻohana ʻia i ka hana ʻana i nā paipu, nā profiles (e like me ka puka a me nā puka makani), nā pepa, nā kiʻiʻoniʻoni, nā uhi kelepona, a me nā mea hou aku. ʻO kona hiki ke hoʻouna kiʻekiʻe e hōʻoia i ka holo ʻana o ka palaka hoʻoheheʻe paʻa, ʻoiai ʻo kāna hopena shearing ikaika e hiki ai i ka hui ʻana o ka plastic me nā mea hoʻohui (e like me masterbatches a me nā antioxidants), e hōʻoiaʻiʻo ana i ka maikaʻi o ka maikaʻi o ka huahana i hoʻopau ʻia.

2. Plastic Granulation: Hoʻoheheʻe ʻia nā ʻōpala plastik, nā mea hana hou, a i ʻole nā ​​​​mea hou i hoʻoheheʻe ʻia, hoʻokuʻu ʻia, a ʻoki ʻia i loko o nā pellets ma o ka wili. ʻO ka hana intermeshing e hōʻoia i ka hoʻoheheʻe ʻana a me ka plasticization o ka plastic, e pale ana i nā lumps unmelted i loko o nā pellets.

3. Hoʻoponopono Plastic Special: Hoʻoponopono i nā plastic me ka wela kiʻekiʻe a me nā koi hoʻohui, e like me PVC (polyvinyl chloride) a me PC (polycarbonate). ʻO kāna kaohi wela kūpono e pale ai i ka PVC mai ka decomposing i nā wela kiʻekiʻe, ʻoiai ʻo kāna hui ʻana like e hōʻoiaʻiʻo i nā waiwai mechanical paʻa o nā huahana PC.

Nā kikoʻī

Hoʻokumu ka hoʻomaʻemaʻe kūpono i kahi "sealing zone" i ka wā o ka hana ʻana, e hōʻemi ana i ke kahe hope o nā mea viscosity kiʻekiʻe i ka hopena hānai ma lalo o ke kaomi a me ka hōʻoia ʻana i ka lawe ikaika ʻana. He mea koʻikoʻi kēia no ka intermeshing conical twin-screw extruders. Mālama ʻo Nanhai Ya i ka hoʻomaʻemaʻe ma waena o nā niho wili ʻelua, me ka hoʻohana ʻana i ka mīkini kiʻekiʻe (e like me ka wili) e hōʻoia i ka ʻae like ʻana.

ʻO ka hoʻomaʻamaʻa kiʻekiʻe, ka mīkini pololei, a me nā kaʻina hana nitriding e hōʻoia i ka hana piha o nā mea nui.

Hoʻoikaika ʻia nā wahi palupalu o ka screw a me ka barela me kahi ʻāpana nickel-tungsten alloy, e loaʻa ana i kahi papa mānoanoa 2-3mm a hoʻomaikaʻi nui i ka pale ʻana i ka lole.
