Extrusion System Malfunction
1. Rough, npub txheej txheej ntawm cov yeeb nkab: Kho cov txheej txheem kub; ntxuav qhov tuag; tswj cov dej txias ntawm 20-25 degrees.
2. grooves lossis roughness ntawm phab ntsa sab hauv: txo cov tub ntxhais kub; nyem lub raj khoob kom nruj kom kaw lub puab kab noj hniav tam sim tom qab pib; ntxuav thiab txhuam cov pwm.
3.Yellowish- xim av streaks lossis me ntsis ntawm qhov chaw ntawm cov yeeb nkab: Ntxuav cov ces kaum tuag ntawm cov pwm; tshuaj xyuas cov khoom siv raw thiab txhim kho cov txheej txheem sib tov.
4.Npaj rau ntawm qhov chaw ntawm cov yeeb nkab: Ntxuav lub qhov cua thiab cov kav dej; me ntsis txo qhov tuag kub.
Dimensional thiab Geometric Defects
1. Cov phab ntsa tuab tsis sib xws: Tshawb xyuas cov cua sov coils; tswj qhov nrawm nrawm nrawm; kho thiab zawm cov pwm bolts.
2.Pipe ovality tshaj qhov tshwj xeeb: Kho lub nozzle kom paub meej txawm tias txias; tswj dej kub tsawg dua lossis sib npaug li 35 degree; nruab ib lub cuab yeej kho.
3.Outer txoj kab uas hla ntawm kev kam rau siab: Tswj lub tshuab nqus tsev ruaj khov thiab rub ceev; kho lossis hloov lub tes tsho loj.
Nqus thiab Moulding teeb meem
1. Tsis muaj lub tshuab nqus tsev lossis lub tshuab nqus tsev tsis tshua muaj: tshem tawm qhov nkag thiab lub raj; tshuaj xyuas thiab kho cov pa tawm; siv cov hlau nyias nyias los tshem cov qhov me me hauv cov pwm pwm.
2.Kho qhov txaus siab uniformity ntawm lub tes tsho sizing; xyuas kom meej tias lub tshuab nqus tsev nyob rau hauv lub rear chamber yog me ntsis siab tshaj qhov nyob rau hauv pem hauv ntej chamber; xyuas qhov tso tawm los ntawm lub ntsiab chav tsev.
Kev daws teeb meem rau kev pub mis thiab txiav cov teeb meem
1. Tsis ruaj tsis khov tam sim no nyob rau hauv lub ntsiab chav tsev: xyuas lub feeder; kho lub cev muaj zog; xyuas lub rhaub; tshem cov ntsia hlau los xyuas thiab kho cov shims thiab cov khoom.
2. Cov khoom siv tsis zoo vibration: Tshawb xyuas thiab kho cov khoom siv qib thiab kev sib tw; kho cov ntsia hlau clearance; hloov qhov hnav; txhawb lub hauv paus.
3.Main motor kiv cua tsis ua hauj lwm ua rau kaw: Tam sim ntawd txo lub load, nruab ib lub kiv cua sab nraud kom txias txias, thiab tam sim ntawd kho los yog hloov lub faulty lub cev muaj zog.
Tshaj tawm -Cov teeb meem vuam
1. Electrofusion vuam abnormality: nres vuam, cia cov sib koom ua ke kom txias, thiab tom qab ntawd rov ua haujlwm; xyuas seb qhov tsis kam ntawm qhov haum yog nyob rau hauv tus qauv ntau yam (xws li, rau DN110 haum, nws yuav tsum yog 0.8-1.2 Ω).
2.Hydraulic system tsis ua hauj lwm nyob rau hauv kub -melt taub qab vuam tshuab: Sau cov hydraulic kua mus rau theem teev; tshuaj xyuas qhov siab -siab hoses thiab ceev- txuas fittings.
