ʻO wai ʻo Conical Twin Screw Barrel no PVC? Paipu vs Papa vs Pepa

Na ka Hui Hana Hana Nanhaiya— Screw & Barrel Engineering, Zhoushan · Nānā ʻia no ka pololei o ka hale hana · ~9 min heluhelu

ʻO ka paipu PVC, ka papa PVC a me ka pepa PVC nā hana nui ʻekolu no apahu pahu māhoe conical- a manaʻo pinepine ka poʻe kūʻai i hoʻokahi pahu e uhi i nā mea ʻekolu. Aneane e hana: ʻo ka māhoe conical screw a me ka barela ka mīkini kūpono no kēlā me kēia extrusion paʻa-PVC. Akā, ʻaʻole like ka ʻaoʻao o ka screw, ka band output a me ka mālama ʻana i ka ʻili e kūpono i ka paipu PVC me ka mea e pono ai ka papa pahu piha piha. Ke hele nei kēia alakaʻi i kēlā me kēia huahana, a laila hōʻike i ke ʻano o ka nui a kuhikuhi i ka mea kūpono.

Paipu PVC pahu pahu māhoe conical

ʻO ka paipu PVC ka noi conical maʻamau. Holo ka laina i ka PVC maloʻo maloʻo, maʻamau me ka calcium carbonate māmā a me ka haʻahaʻa, a ʻo ka mea nui loa ʻo ia ka hoʻopuka paʻa a me ka hoʻoheheʻe paʻa no laila e kūpaʻa ka mānoanoa o ka pā ma ka paipu. Hoʻohana maikaʻi ʻia kēia pahu pahu pahu conical: huki ka hopena hānai nui i ka pauka māmā, a ʻo ka hoʻopili ʻana i ka tapered e hana i kahi hoʻoheheʻe haʻahaʻa haʻahaʻa e pale ai i ka PVC wela.

No kahi paipu PVC conical twin screw barrel, e koho mua:

• Ke ana ʻana like- kahi ʻaoʻao wili i hoʻopaʻa ʻia no ke kaomi mau a me ka puka.
• Ka nui ana i ka hoopuka ana- nā lakio anawaena nui aʻe no ka paipu anana nui (ʻoi aku ka nui ma lalo).
• E hoʻohana i ka pale e hoʻohālikelike i ka mea hoʻopihapiha- nitrided no nā papa maʻemaʻe, bimetallic ke piʻi ʻo CaCO₃.

E ʻike i kā mākoupahu pahu māhoe conicalka laulā no nā hoʻonohonoho paipu, a i ʻole ke kiʻekiʻe-throughputʻO ka paipa PVC paipu hoʻoheheʻe ʻiainā ʻoe e holo i kahi laina like.

ʻO ka pahu PVC pahu pahu māhoe conical

ʻO ka papa PVC - ʻoi aku ka papa pahu a me ka papa ʻaina manuahi - ʻoi aku ka koi. Lawe pinepine nā formulations i ka mea hoʻopihapiha kiʻekiʻe, a ʻo ka hoʻoulu ʻana e hoʻohui i ka naʻau i ka hoʻoheheʻe ʻana i ka mahana a me ka paʻa paʻa, no ka mea, ʻike ʻia nā kūlana like ʻole e like me ke ʻano like ʻole o ka hale a me ka nui. AʻO ka pahu PVC pahu pahu māhoe conicalNo laila, kūkulu ʻia a puni ka wela hoʻoheheʻe ʻia, ka hoʻokuʻu maikaʻi ʻana a me ke kūpaʻa ʻoi aku ka ikaika ma mua o ka pono o ka pahu paipu maʻemaʻe.

ʻO ka mea hoʻopiha kiʻekiʻe ke ʻano o ka abrasion, no laila ʻo nā pahu papa kahi e hoʻomaka ai ka pale bimetallic e loaʻa i kāna mālama - ʻo kahi ʻāpana tungsten-hoʻohui ʻia e kūʻē i ka calcium carbonate e wili ʻia i loko o kahi pahu nitrided lahilahi i ʻoi aku ka wikiwiki ma ka laina pahu-papa.

Pvc pepa pahu pahu māhoe conical

ʻO ka pepa PVC - mai ka pepa ʻoʻoleʻa lahilahi a hiki i ka hiʻohiʻona marble a me ka pepa PVC palupalu - noho ma waena o ka paipu a me ka papa i kāna koi. Hoʻokomo ka like ʻana o ka puka i ka maikaʻi o ka ʻili a me ka ʻae ʻana i ka mānoanoa ma o ka pūnaewele, no laila ʻo ka hoʻoheheʻe paʻa, homogenised maikaʻi ka mea nui. ʻOkoʻa nui nā pae hoʻopiha ma ka huahana, ʻo ia ke kumu nui o ka koho ʻana i ka mālama ʻana i ka ʻili: pono ka pale ʻana o ka ʻōpala me ka hoʻopiha mineral koʻikoʻi i ka pale bimetallic, ʻoiai e holo hauʻoli ana ka lau maʻemaʻe ma ka nitrided.

Ma muli o ka ʻokoʻa loa o ka hoʻokumu ʻana o ka pepa, ʻaneʻane e kuhikuhi mau ʻia kahi pahu PVC sheet conical twin screw barrel i ke ʻano kikoʻī a me ka laina - ʻaʻohe "sheet barrel" hoʻokahi. E kaʻana like i kāu mea a me ka pae hoʻopihapiha a hiki ke hoʻohālikelike ʻia ka ʻaoʻao a me ka ʻili.

PVC paipu vs papa vs pepa: he aha ka hoʻololi

ʻO ka lawe ʻana: noho conical ka geometry no nā mea ʻekolu, akā i kou neʻe ʻana mai ka paipu maʻemaʻe a hiki i ka papa puaʻa piha, lilo ka pale lole i mea hoʻoholo.

ʻO ka nui a me ka pili o ka mīkini

Hoʻokumu ʻia nā pahu conical e like me nā koho nui maʻamau - ke anawaena hānai a me ka make ma nā millimeters. E hoʻohālikelike i ka nui me kāu extruder a me kāu pukana i manaʻo ʻia:

ʻAʻole hiki ke kūʻai ʻia ka loaʻa ʻana o ka nui: maʻamau ka pahu conical i ka mīkini e holo ai i loko, no laila pono e kūlike ke anawaena hānai/make, mamao waena, ka lōʻihi a me nā kikoʻī flange i kāu extruder pololei. No ka mīkini ponoʻī, e ʻike i kā mākoumea hoʻokuke māhoe māhoelaulā a pihanā mīkini extruder.

Nitrided a bimetallic paha no PVC?

ʻO kēia ka koho e pili nui i ka lōʻihi o ka pahu PVC. I ka pōkole: maʻemaʻe, haʻahaʻa-hoʻopiha PVC hiki ke holo nitrided; PVC piha piha - ʻo ka hapa nui o ka papa puaa a me ka pepa i hoʻopiha ʻia me ka mineral - he bimetallic. He abrasive ka PVC (mai ka mea hoʻopiha) a me ka corrosive (HCl i hoʻokuʻu ʻia ma ka thermal decomposition), no laila, ma ke koi ʻana i nā formula, e uku hou ʻia kahi ʻāpana paʻa paʻa i ka lōʻihi o ka lawelawe ʻana.

Hoʻopili ʻo Nanhaiya i kahi huila paʻa i hoʻohui ʻia i ka tungsten a puni ka ʻāpana ʻaʻahu maʻalahi o ka barela, hiki62 HRCi loko o ka lua - e kū'ē i kahi 58 HRC maʻamau - me kahi papa huila 2.5–3 mm. Kūkulu mākou i kēia mau mea ma 38CrMoAlA, W6Mo5Cr4V2 a i ʻole HIP kino pauka-hao. No ka hoʻohālikelike piha, e ʻike i kā mākou alakaʻi i ke koho ʻana ma waena o abimetallic conical māhoe māhoea me nā ili maʻamau.

Pehea e kauoha ai i ka pahu conical kūpono no PVC

No ka loaʻa ʻana o kahi pahu kūpono kūpono ma mua o kahi hoʻohālikelike, e hoʻouna mai iā mākou:

1. Huahana- ka paipu, ka papa a i ʻole ka lau, me ke ʻano hoʻopiha a me ka pae (e.g. CaCO₃ hoʻouka).
2. Nā kikoʻī mīkini— brand/model extruder, a i ʻole he kiʻi me ke anawaena hānai/make, mamao waena, lōʻihi a me ka flange.
3. Hoʻopuka pahuhopu— kg/h a me ka wikiwiki o ka laina, no laila ke kūlike ka ʻaoʻao a me ka nui.
4. Kūlana holo- nā hola o ka lā a me ke ʻano o ka abrasive o ke ʻano, no laila ke paipai nei mākou i ka nitrided a i ʻole bimetallic ʻoiaʻiʻo.

Me kēlā mau hoʻokomo ʻehā, hiki i kā mākou ʻenekini ke ʻōlelo i kahi pahu pahu conical i hoʻohālikelike ʻia me kāu laina PVC i loko o 12 mau hola.
