Intermeshing Conical Twin Screw

Nanhaiya screw ke moetsi oa pele oa Chaena ea sebetsanang le tlhahiso ea intermeshing conical twin screw. Ka boiphihlelo bo fetang lilemo tse leshome mochining oa polasetiki, re sebelisa lits'ebetso tse tsoetseng pele tsa tlhahiso le lisebelisoa ho rala le ho etsa mefuta e mengata ea li-screw. Lihlahisoa tsa rona li fana ka litheko tsa tlholisano ebile li koahela mebaraka e mengata ea Europe le Amerika. Re labalabela ho ba molekane oa hau oa nako e telele Chaena.

Kenyelletso ea Sehlahisoa

Sekoti sena sa mafahla se kopaneng se entsoe ka tšepe ea 38CrMoAla. Lintho tse tala li bohlokoa haholo bakeng sa ts'ebetso ea "screw", 'me re khetha litšepe tse matla le tse sa senyeheng ho tsoa ho baetsi ba litšepe ba tsebahalang ba Machaena ba fihlelang maemo a naha (GB/T 3077).

Re sebelisa mokhoa oa ho roala likhoele. Ts'ebetso ena e etsa hore ho be le khoele e tletseng, e matla haholoanyane, e thibelang ho senya. E boetse e laola phoso ea molumo oa khoele ho ≤0.1mm, e netefatsa ho kopanela ka mokhoa o ts'oanang le ho fokotsa ho lokoloha.

Nanhaiya's intermeshing conical twin screw barrel e fetile R&D le lintlafatso tse ngata mme joale li kenyelelitsoe mehala ea tlhahiso ea bahlahisi ba fapaneng, ho fihlela ts'ebetso ea maemo a holimo. Re fana ka tiisetso ea lilemo tse 1-2, ho latela tekanyo e khethehileng ea tlatsetso ea thepa. Libarele tsa Nanhaiya li kena tšebetsong ea nitriding, tse nang le lesela le tenya la 2mm la nickel-tungsten alloy alloy-welded libakeng tse tloaelehileng haholo. Sena se eketsa boima ba holim'a barrel ho tloha ho HRC55-60 ho ea ho HRC65, ho matlafatsa khanyetso ea ho apara ka makhetlo a 2-4.

Paramethara (Tlhahiso)

Litlhaloso tsa conical twin screw le barrel

Tšobotsi le Tšebeliso

1. Phatlalatso ea Lintho: E Qobelloa ebile e Tsitsitse, Ha ho Backflow

Sebopeho sa intermeshing se etsa "kamore ea thepa" e koetsoeng e sutumelletsang thepa ka likhoka, e felisa ka ho feletseng bothata ba ho khutlela morao bo amanang le li-screws tse tlaase kapa tse se nang meshing.

Katleho ea ho fetisa ha e amehe haholo ke viscosity ea lintho tse bonahalang. Esita le ha u sebetsana le lisebelisoa tsa viscous tse kang polasetiki e qhibilihisitsoeng le li-slurries tse teteaneng haholo, tekanyo ea phepo e tsitsitseng e ka bolokoa, ho netefatsa tlhahiso e tsoelang pele.

2. Ho Kopanya le Ho Beola: Phello e Matla, E Uniform e Phahameng

Ha li-screws tse peli li le intermesh, li sebelisa ketso e meraro ea "ho kuta," "ho luba," le "ho oela" holim'a lintho tse bonahalang, ka potlako ho senya li-agglomerate tsa lintho tse bonahalang le ho finyella microscopically junifomo ho kopanya likarolo.

Bokhoni bona bo matla ba ho kuta bo boetse bo thusa ho qhibiliha kapa ho arabela. Ka mohlala, ka extrusion ea polasetiki, e ka khutsufatsa nako ea ho qhibiliha 'me ea finyella boleng bo bongata ba ho qhibiliha.

3. Khatello le Mocheso: Ho Laoleha Haholo, Ho Loketse Ts'ebetso e Phahameng ea Khatello

Kamore e koetsoeng e theha le ho boloka khatello e tsitsitseng ea ts'ebetso, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse hlokang khatello, joalo ka khatello ea boholo ho extrusion ea lipeipi tsa polasetiki le karabelo e matla ea lisebelisoa tse sebetsang. Nako ea ho lula ha thepa ka har'a kamore e koetsoeng e batla e tsitsitse, 'me phapanyetsano ea mocheso pakeng tsa screw le barrel e tšoana haholo, e nolofalletsang taolo e nepahetseng ea mocheso oa thepa le ho thibela ho chesa haholo kapa ho se lekane ha mocheso ho ka lebisang ho senyeha ha thepa.

4. Sebaka sa Kopo: Tharollo e Lebisitsoeng bakeng sa Litlhoko tse thata tsa ho sebetsa

Sena se loketse ka ho khetheha bakeng sa thepa e nang le viscosity e phahameng, elasticity e phahameng, 'me e hloka ho tsoakoa hantle, joalo ka polasetiki, rabara, likhomaretsi le liphahlo tse phahameng haholo.

Ha li bapisoa le li-screws tse ling, li-screws tsa Nanhaiya tse kopanyang li-conical li fokotsa masala a thepa ka har'a thepa, li nolofatsa ho hloekisa nakong ea liphetoho tsa thepa le ho ntlafatsa katleho ea tlhahiso ka tsela e sa tobang.

 Likarolo tsa mantlha tsa ts'ebeliso ea li-intermeshing conical twin-screw extruder li koahela hoo e ka bang mohato o mong le o mong oa bohlokoa ts'ebetsong ea ho lokisa lipolasetiki, ho tloha ho lisebelisoa tse tala ho isa lihlahisoa tse felileng.

1. Plastiki Extrusion: E sebelisoa ha ho etsoa liphaephe, litlaleho (tse kang liforeimi tsa menyako le lifensetere), maqephe, lifilimi, likoahelo tsa cable, le tse ling. Bokhoni ba eona bo phahameng ba ho tsamaisa bo netefatsa phallo e tsitsitseng ea ho qhibiliha ha polasetiki, ha phello ea eona e matla ea ho kuta e lumella ho kopanya ka botlalo polasetiki le li-additives (tse kang masterbatches le li-antioxidants), ho netefatsa boleng bo lekanang sehlahisoa se felileng.

2. Plastiki Granulation: Likhechana tsa polasetiki, lisebelisoa tse tsosolositsoeng, kapa lisebelisoa tse ncha lia qhibiliha, li ntšoa, 'me li khaoloa ka li-pellets ka screw. Sebopeho sa intermeshing se tiisa ho qhibiliha ka ho feletseng le polasetiki ea polasetiki, ho thibela maqeba a sa qhibilihang ka har'a li-pellets.

3. Tšebeliso e khethehileng ea Plastiki: Ho sebetsa lipolasetiki tse nang le mocheso o phahameng le litlhoko tsa ho kopanya, tse kang PVC (polyvinyl chloride) le PC (polycarbonate). Taolo ea eona e nepahetseng ea mocheso e thibela PVC hore e se ke ea bola ka mocheso o phahameng, ha ho kopanya ha eona junifomo ho tiisa thepa e tsitsitseng ea mechine ea lihlahisoa tsa PC.

Lintlha

Ho tlosoa ka mokhoa o utloahalang ho theha "sebaka sa ho tiisa" nakong ea ts'ebetso ea screw, ho fokotsa ho khutla ha lisebelisoa tse nang le viscosity ho ea pheletsong ea phepelo tlas'a khatello le ho netefatsa phepelo e qobelloang e sebetsang. Sena ke sa bohlokoa ka ho khetheha bakeng sa ho kopanya li-extruder tsa conical twin-screw. Nanhai Ya o laola ka tieo sebaka se pakeng tsa meno a mabeli a screw, a sebelisa machining a phahameng haholo (joalo ka ho sila) ho etsa bonnete ba hore ho na le sebaka se tšoanang.

Mekhoa e tsoetseng pele ea ho futhumatsa, ho sebetsa ka mokhoa o nepahetseng, le lits'ebetso tsa nitriding li netefatsa ts'ebetso e felletseng ea likarolo tsa mantlha.

Libaka tse tlokotsing tsa screw le barrel li matlafatsoa ka lera la nickel-tungsten alloy, ho fihlela lera le teteaneng la 2-3mm le ho ntlafatsa haholo ho hanyetsa ho apara.
