Ho khetha se nepahetsenggearbox ea extrudere bohlokoa bakeng sa ho netefatsa ts'ebetso e tsitsitseng, ts'ebetso e phahameng ea tlhahiso le bophelo bo bolelele ba ts'ebeletso ea lisebelisoa tsa polasetiki tsa extrusion. Lisebelisoa tse fapaneng tsa extrusion li hloka meralo e fapaneng ea li-gearbox tse thehiloeng ho mofuta oa screw, torque ea tlhahiso, lebelo la lebelo, litšobotsi tsa thepa le litlhoko tsa tlhahiso.
E le setsebimorekisi oa li-gearbox tsa indasteri, re fana ka litharollo tsa phetiso tse ikhethileng bakeng sa tse fapanengmechine ea polasetiki ea extrusion.
Tšebeliso ea Single Screw Extruders
A lebokose la gearbox e le 'ngoe ea screw extruder e sebelisoa haholo-holo bakeng sa mekhoa ea extrusion ea polasetiki e hlokang ho qhibiliha ho tsoelang pele, ho kopanya le ho tsamaisa.
Lisebelisoa tse tloaelehileng li kenyelletsa:
- Tlhahiso ea liphaephe tsa polasetiki
- Plastiki profiles extrusion
- Lihlahisoa tsa polasetiki le lipoleiti
- Extrusion ea lifilimi
- terata le thapo extrusion
- Recycling extrusion lines
Lisebelisoa tse tloaelehileng tsa ho sebetsa:
- PE (Polyethylene)
- PP (Polypropylene)
- PVC
- ABS
- PET
- Lisebelisoa tse ling tsa thermoplastic
Mekhahlelo ea Bohlokoa bakeng sa Khetho e le 'ngoe ea Screw Extruder Gearbox
1. Screw Diameter
Sekhahla sa screw se ama ka kotloloho tlhahiso ea extrusion le torque e hlokahalang.
Mefuta e tloaelehileng:
- 30mm-90mm bakeng sa mechini e nyane ea extrusion
- 90mm-200mm bakeng sa mela e mahareng le e meholo ea extrusion
- 200mm+ bakeng sa lisebelisoa tse boima - tsa mosebetsi oa extrusion
Hangata screw e kholoanyane e hloka lebokose la gear le nang le:
- Torque e phahameng ea tlhahiso
- Matla a ho jara
- Matla a ho jara a maholo
2. Matla a Motlakase
Lebokose la gear le lokela ho khethoa ho latela matla a motlakase a extruder.
Mofuta o tloaelehileng oa matla:
- Li-extruder tse nyane: 5.5kW - 45kW
- Li-extruder tse mahareng: 45kW-160kW
- Li-extruder tse kholo: 160kW le holimo
Lebokose la gear le tlameha ho fana ka torque e lekaneng ho netefatsa ts'ebetso e boreleli ea extrusion.
3. Tlhokahalo ea Torque ea Output
Torque ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa tsa ho khethagearbox ea extruder.
Meralo e phahameng ea li-gearbox ea torque e khothaletsoa bakeng sa:
- Lisebelisoa tse phahameng tsa ho tlatsa
- Khatello e phahameng ea khatello
- Liphaephe tse kholo tsa bophara
- Boima-ho sebetsa ka polasetiki
4. Karolelano ea Lebelo
Karolelano ea phokotso ea li-gearbox e lokela ho ts'oana le lebelo le hlokahalang la screw.
Likarolo tse tloaelehileng tsa li-gearbox tsa extrusion:
- 8:1
- 10:1
- 12:5:1
- 16:1
- 20:1
- Likarolo tse ikhethileng lia fumaneha
