Li-extruder tsa polasetiki ke lisebelisoa tsa mantlha indastering ea ho lokisa lipolasetiki, 'me ts'ebetso ea tsona e tsitsitseng e ama ka kotloloho katleho ea tlhahiso le boleng ba sehlahisoa. Leha ho le joalo, ka lebaka la ho lula-nakong e telele ho lithempereichara tse holimo, likhatello tse phahameng, le mejaro e phahameng, li-extruder li ka qojoa ka lebaka la ho hloleha ho itseng ka mechine kapa ho senyeha ha tšebetso. Ka hona, ho tseba mekhoa ea mahlale ea tokiso le maano a tlhokomelo ho bohlokoa ho lelefatsa bophelo ba lisebelisoa le ho fokotsa litšenyehelo tsa tlhahiso. Sengoliloeng sena se tla sekaseka tlhahlobo e tloaelehileng ea liphoso, mekhoa ea bohlokoa ea ho lokisoa, le likhothaletso tse tloaelehileng tsa tlhokomelo.
1. Mefuta ea Phoso e Tloaelehileng ea Plastic Extruder le Mekhoa ea Tlhahlobo
Liphoso tsa polasetiki tsa extruder ka kakaretso li ka aroloa ka mefuta e meraro ea mantlha: mochini, motlakase le ts'ebetso. Liphoso tsa mochini li kenyelletsa ho roaloa ha screw, ho jara tšenyo, le mathata a sistimi ea phetisetso. Hangata liphoso tsa motlakase li kenyelletsa mocheso o feteletseng oa motlakase, ho se sebetse hantle ha potoloho, kapa ho se sebetse hantle ha inverter. Mathata a tšebetso a bonahala e le ho hloleha ha taolo ea mocheso, ho feto-fetoha ha khatello, kapa ho ntša metsi ka tsela e sa lekanang.
Ho fumana phoso ho hloka-mehato e meraro: "Sheba-Teko-Hlahloba." Ntlha ea pele, hlahloba lisebelisoa ka mahlo bakeng sa ho lutla, lerata le sa tloaelehang, kapa ho senyeha ha likaroloana. Ea bobeli, sebelisa li-thermometer tsa infrared le li-analyzer tsa vibrate ho lekola mocheso le ho sisinyeha ha likarolo tsa bohlokoa (tse kang litulo le li-gearbox). Qetellong, sekaseka mekhoa e fetohang ea liparamente tsa ts'ebetso (joalo ka mocheso oa ho qhibiliha le khatello ea extrusion) ho fumana ka botlalo sesosa sa phoso. Ka mohlala, haeba extruder e tsoa ka mokhoa o sa tsitsang o tsamaeang le motlakase o phahameng ka tsela e sa tloaelehang, sena se ka bakoa ke ho roala ha screw kapa ho fepa ka tsela e sa tšoaneng, e hlokang ho qhaqhoa le ho hlahlojoa hape.
II. Lintlha tsa Bohlokoa tsa Tekheniki bakeng sa Tokiso ea Plastic Extruder
Tokiso le Phetoho ea Likarolo tsa Bohlokoa
Screw le barrel ke likarolo tsa mantlha tsa extruder, 'me moaparo oa bona o ama ka kotloloho phello ea polasetiki. Haeba sekoahelo sa holim'a sefahleho se feta 0.5mm kapa ho hlaha mengoapo, ho lokisoa hoa hlokahala ka ho tjheseletsa sekoahelo se thata sa alloy kapa ho busetsa screw. Haeba lebota la barrel le se le tsofetse, ho nepahala ho ka khutlisoa ka ho tena le ho kenya-li-resistant bushings. Ho feta moo, likere le li-bearings tsamaisong ea phetisetso li hloka tlhahlobo ea khafetsa bakeng sa ho tlotsa. Haeba ho na le likoti kapa ho na le tumello e feteletseng ea ho beleha, li tlameha ho nkeloa sebaka hang-hang ho thibela tšenyo ea cascading.
Tlhokomelo ea Litsamaiso tsa ho futhumatsa le ho futhumatsa
Ho hloleha ho laola mocheso ke ho se sebetse ho tloaelehileng ha li-extruder. Nakong ea tlhokomelo, tsepamisa maikutlo ho hlahloba ho hanyetsa ha mocheso oa mocheso (ho kheloha leha e le efe ho feta ± 10% ho hloka ho nkeloa sebaka), litekanyetso tsa PID tsa molaoli oa mocheso, le ho hloekisa li-deposit leha e le life tsa carbon ho tloha nthong ea ho futhumatsa. Haeba sekala se koala mohala oa metsi a pholileng, se fokotsa ts'ebetso e ntle ea ho qhala mocheso, potoloha mochini o hloekisang o nang le asiti ho o hlakola. Hape, hlahloba hore khatello ea pompo ea metsi e lumellana le maemo (hangata E kholo ho feta kapa e lekana le 0.3 MPa).
Ho rarolla mathata a Sisteme ea Taolo ea Motlakase
Li-extruder tsa sejoale-joale li na le lisebelisoa tsa PLC kapa li-touchscreen control system. Ha u lokisa litsamaiso tsena, etelletsa pele ho hlahloba mochini oa matla le likhoele tsa matšoao a sensor bakeng sa ho kopana hampe le ho sebelisa oscilloscope ho netefatsa botsitso ba lets'oao la taolo. Bakeng sa liphoso tsa inverter, hlahloba hore na fan e pholileng e sebetsa hantle 'me u lekanye maqhubu a tlhahiso ho netefatsa hore e lumellana le liparamente tse lekantsoeng tsa motor.
III. Mehato ea Tlhokomelo ea Letsatsi le Letsatsi le Mehato ea Thibelo bakeng sa Li-extruders tsa Plastiki
Tlhokomelo ea thibelo ke senotlolo sa ho fokotsa ho hloleha ho sa lebelloang. Mekhoa e latelang ea ts'ebetso e khothaletsoa:
Ho Hloekisa Kamehla le ho Tlatsa: Hloekisa lintho tse setseng ho tloha boema-kepe ba phepelo ea libarele nako le nako ho thibela ho thiba le ho thiba. Likarolo tsa phetiso (joalo ka gearbox) li lokela ho tlotsoa khafetsa ho latela litlhaloso tsa moetsi ho thibela khohlano e omileng.
Tlhokomelo le Rekoto ea Paramethara:{0}}ho rekota nako ea 'nete ea mocheso o fetelletseng, khatello, le lintlha tsa morao-rao tsa mochini li ka sebelisoa ho tseba mathata a ka bang teng ka ho bapisa mekhoa ea nalane (mohlala, lithempereichara tse phahameng ka nako e itseng li ka bontša botsofali ba hitara).
Consumable Parts Inventory Management: Likarolo tsa thepa hangata li nkeloa sebaka joalo ka li-screw le litiiso tse ipapisitseng le nako ea ts'ebetso ea lisebelisoa ho netefatsa karabelo e potlakileng ha phoso e etsahala.
Ho boloka extruder ea polasetiki ke ts'ebetso e hlophisehileng e hlokang hore ho rarolloe mathata ka nepo ka liphoso tse itseng le taolo ea mahlale ea tlhokomelo ea kamehla. Mekhoa e tloaelehileng ea ho hlahloba liphoso, mekhoa e hloekisitsoeng ea ho lokisa likaroloana, le mehato ea thibelo e sebetsang e ka ntlafatsa haholo botšepehi ba lisebelisoa le tsoelo-pele ea tlhahiso. Likhamphani li lokela ho etelletsa pele koetliso ea litsebo bakeng sa basebetsi ba tlhokomelo le ho kenyelletsa mekhoa e hlalefileng ea ho beha leihlo (joalo ka tlhahlobo ea vibrate le AI{2}based fault prediction) ho ntšetsa pele tlhokomelo e nepahetseng le e nepahetseng ea extruder.
