Litharollo tse Atlehang tsa ho Fokotsa Nako ea ho Phokotsa Nako ka Meqomong ea Twin-Screw Extruder
Ho ntlafatsa ts'ebetso ea li-twin-screw extruder, bahlahisi ba tlameha ho kenya tšebetsong litharollo tse sebetsang tse fokotsang nako. Litharollo tsena li kenyelletsa maano a khetho ea thepa, maemo a ntlafetseng a ts'ebetso, le mekhoa ea thibelo ea tlhokomelo.
Maano a Khetho ea Lintho
Ho khetha thepa e nepahetsengbakeng sa libarele tsa "twin-screw extruder" li bohlokoa bakeng sa bophelo bo bolelele le ts'ebetso. Tafole e latelang e bontša mefuta e fapaneng ea lisebelisoa le melemo ea tsona ea bohlokoa:
| Mofuta oa Boitsebiso | Melemo ea Bohlokoa |
|---|---|
| Tšepe ea carbon | Ho tšoarella ha motheo |
| Ts'epe e sa beng le mabali | Khanyetso e ntle ea kutu |
| Tšepe ea motsoako | Lisebelisoa tse ntlafalitsoeng tsa mochini |
| Tšepe ea phofo ea metallurgy | Ho apara ka mokhoa o phahameng le ho hanyetsa kutu, sebopeho se setle sa lijo-thollo, matla a phahameng a mochine, bophelo bo bolelele ba tšebeletso |
Ho sebelisa litlolo tse tsoetseng pele kapa kalafo ea holim'a metsi ho ka ntlafatsa le ho feta ho hanyetsa ho apara. Mohlala, liphekolo tsa nitriding li ka lelefatsa bophelo ba li-screws ka makhetlo a mabeli ho isa ho a mararo. Ho feta moo, chromium le molybdenum plating li matlafatsa ho thatafala le ho se mamelle, ho ntlafatsa haholo ts'ebetso ea moqomo.
Optimized Processing Conditions
Ho theha libaka tse loketseng tsa ho sebetsa ho bohlokoa bakeng sa ho boloka ts'ebetso e tsitsitseng ea thepa. Ho kenya ts'ebetsong mekhoa e tloaelehileng ea ts'ebetso ho ka laola mekhoa ea ts'ebetso ka katleho. Litharollo tse latelang li ka ntlafatsa maemo a ts'ebetso:
- Laola Mocheso le Khatello: Boloka mocheso o tsitsitseng le khatello ea ho thibela ho roala ha mocheso le ho etsa bonnete ba ho phalla ha lintho tse tsitsitseng.
- Lekola Sebopeho sa Lintho: Kamehla hlahloba sebopeho sa lisebelisoa tse ntseng li sebetsoa ho qoba ho roala ho tsoa ho li-fillers.
- Fetola Lebelo la Screw: Ntlafatsa lebelo la screw ho leka-lekanya katleho ea ho kopanya le ho hlahisa mocheso, ho thibela ho chesa haholo.
Ka ho sebelisa mekhoa ena, bahlahisi ba ka fokotsa haholo ho roala libarele tse tšoarellang tsa twin-screw extruder le ho ntlafatsa katleho ea tlhahiso ka kakaretso.
Mekhoa ea Thibelo ea Tlhokomelo
Moralo o tiileng oa tlhokomelo o bohlokoa bakeng sa ho fokotsa nako e sa reroang. Tafole e latelang e totobatsamekhoa e sebetsang ea ho thibela ho boloka:
| Itloaetse | Tlhaloso |
|---|---|
| Mananeo a Tloaelo a Tlhokomelo | Tlhokomelo ea kamehla e tiisa hore mechini e sebetsa hantle 'me e qoba ho senyeha ho sa lebelloang. |
| Koetliso ea Basebetsi | Basebelisi ba rutehileng ba ka tseba matšoao a pele a ho khathala le ho rarolla mathata a manyane pele a ka mpefala. |
| Spare Parts Inventory | Ho boloka lethathamo la likarolo tsa bohlokoa ho netefatsa litokiso tse potlakileng le ho fokotsa nako ea ho theoha. |
| Lisebelisoa tsa boleng bo holimo | Likarolo tse entsoeng ka thepa e tšoarellang li ntlafatsa ts'ebetso le ho fokotsa litlhoko tsa tlhokomelo. |
| Lubrication e nepahetseng | Lisebelisoa tsa boleng bo holimo li fokotsa khohlano, li lelefatsa bophelo ba likaroloana, 'me li ntlafatsa ts'ebetso e akaretsang. |
| Litlhahlobo Tsa Kamehla | Ho hlahloba hore na ha ho na ho senyeha ho ka thibela ho lokisoa ha theko e boima le nako e fokolang, ho boloka boleng bo tsitsitseng ba sehlahisoa. |
Litlhahlobo tsa tlhokomelo li lokela ho etsahala khafetsa ho ntlafatsa nako ea ts'ebetso ea libarele tse peli tsa screw extruder. Mohlala, ho fetola oli le oli e tlotsang lihora tse ling le tse ling tse 4000 le ho hlahloba liaparo tsa kotara ho ka thibela mathata a bohlokoa.
Ka ho kenya ts'ebetsong litharollo tsena tse sebetsang hantle, bahlahisi ba ka fokotsa nako ea ho theoha haholo le ho ntlafatsa katleho ea mesebetsi ea bona ea mafahla-screw extruder.
Baetsi ba ka fokotsa haholo nako ea ho theoha le ho apara ka ho sebelisa mekhoa e sebetsang ea tlhokomelo. Litlhahlobo tsa khafetsa, licheke tsa ho tlotsa, le litokiso tse nakong li netefatsa ts'ebetso e nepahetseng.Ho theha likamano tse matla tsa bafani ba thepae matlafatsa phihlello ea likarolo tsa boleng bo holimo le tšehetso ea litsebi. Tšebelisano ena e fana ka litharollo tse ikhethileng tse lumellanang le litlhoko tse ikhethileng tsa ts'ebetso, 'me qetellong li tsamaisa tlhahiso le katleho.
Liketso tsa Tlhokomelo ea Bohlokoa:
- Litlhahlobo tsa pono tsa letsatsi le letsatsi le licheke tsa lubrication
- Litlhahlobo tsa khoeli le khoeli tsa screw le barrel
- Liphetoho tsa selemo le selemo tsa sistimi e felletseng
Ka ho beha mekhoa ena pele, bahlahisi ba ka fumana katleho ea ts'ebetso ea nako e telele.
