Lub kaw lus kub khiav ua tiav suav nrog plaub yam khoom tseem ceeb: nozzles, manifolds, ntsuas kub, thiab cov khoom sib koom ua ke-nrog cov thermocouples sib xyaw ua ke rau txhua qhov kom qhib lub voj voog thermal tswj. Nkag siab txog lawv cov kev teeb tsa yog qhov tseem ceeb rau kev xaiv txoj cai rau cov ntawv thov tshwj xeeb.
Kub khiav nozzles yog qhov kawg interface ntawm lub manifold thiab pwm kab noj hniav, muaj nyob rau hauv ob lub ntsiab: qhib-hom thiab valve-qhov rooj (koob-valve). Qhib nozzles yog qhov yooj yim thiab siv tau zoo, haum rau cov khoom siv dav dav xws li PP thiab ABS; lawv muaj ib qho K-hom thermocouple nyob ze ntawm lub taub hau lub taub hau los saib xyuas lub qhov rooj kub thiab tiv thaiv kom tsis txhob khov. Valve-gate nozzles siv lub pneumatic lossis hydraulic koob los tswj lub qhov rooj qhib / kaw, zoo tagnrho rau cov khoom siv siab nrog cov vestige tsawg; lawv feem ntau suav nrog ob lub thermocouples- ib qho ntawm lub taub thiab ib qho ntawm lub tes tsho lub tshuab rhaub- kom sib npaug ntawm qhov kub thiab txias thiab tiv thaiv kom tsis txhob poob dej.
Manifolds (daim phaj) faib cov yaj los ntawm lub tshuab nozzle mus rau ib tus neeg kub lub nozzles, ua raws li qhov system "traffic hub". Lawv yog tsim los ntawm P20 los yog H13 steel, nrog rau sab hauv ntws raws thiab embedded cartridge heaters. Standard manifolds siv ib lub thermocouple rau ib cheeb tsam (feem ntau 2-4 aav) mounted nyob rau hauv ib lub qhov drilled nrog hlau-rau-hlau sib cuag; high-performance manifolds ntxiv cov thermocouples nyob ze ntawm qhov tseem ceeb junctions kom pom cov cua sov tsis sib xws thiab sib npaug. Rau ntau cov kab noj hniav pwm (16-128 kab noj hniav), manifolds feature symmetrical designs nrog matched thermocouple qhov chaw los xyuas kom meej qhov kub thiab txias profiles thoob plaws txhua lub rooj vag.
Cov tswj kub kub yog "lub hlwb" ntawm lub cev kub khiav, tau txais cov cim qhia ntawm thermocouple thiab tswj cov khoom tso cua sov. Cov tswj niaj hnub txhawb nqa 4-64 thaj chaw, lees txais K-hom (tus qauv) lossis J-hom (siab kub) thermocouples. Cov yam ntxwv tseem ceeb muaj xws li "qhib / luv" kev tshawb pom (ua los ntawm qhov tsis muaj qhov kawg lossis xoom thermocouple tsis kam), auto-tuning PID, thiab cov ntaub ntawv kaw rau cov txheej txheem traceability. Cov qauv hwm zoo muab cov khoom siv thermocouple rov ua dua, tso cai rau lub kaw lus hloov mus rau lub ntsuas hluav taws xob yog tias thawj qhov ua tsis tiav.
Cov khoom siv pabcuam muaj xws li cov khoom siv cua sov (cartridge, coil, lossis band), thermocouple cables, connectors, thiab seals. Thermocouple cables yog cov khoom ruaj khov (rau kev teeb tsa ruaj khov) lossis hloov tau (rau pwm txav), nrog cov xim-coded polarity (K-hom: liab=tsis zoo, daj=zoo) los tiv thaiv kev rov qab kev sib txuas tsis raug. Cov khoom sib txuas yog kub-resistant (txog 500 degree) nrog kub-plated pins los tiv thaiv oxidation thiab xyuas kom ruaj khov hluav taws xob tiv tauj.
Hauv cov ntsiab lus, cov khoom kub khiav yog tsim los ua ib qho kev sib koom ua ke, nrog rau cov thermocouples tau muab tso rau hauv kev saib xyuas txhua qhov chaw thermal tseem ceeb. Nozzles tsom ntsoov rau qhov kub thiab txias, manifolds xyuas kom muaj kev sib npaug sib npaug, cov tswj tau muab cov kev tswj xyuas meej, thiab cov koom haum tswj xyuas cov teeb liab sib kis tau zoo. Ua ke, lawv xa cov khoom zoo sib xws, zoo molding.
