Yamukela ushintsho kuphela uma luhlangabezana nekhwalithi echazwe ngaphambilini kanye nemibandela yokusebenza. Uma ihluleka, londoloza okutholiwe futhi ulandele inqubo yokubuyisela egunyaziwe noma yokubuyekeza esikhundleni sokwengeza omunye umkhawulo ngaphandle kwe-hypothesis entsha.
Esikudingayo ngengxenye kafushane
Thumela umazisi womshini, umdwebo wokumisa, i-diameter yesikulufu esivamile, ibanga eliphakathi nendawo, imininingwane yokuxhumana ye-shaft noma yedrayivu, nanoma iyiphi imephu yokuguga ekaliliwe. Faka okubalulekile namarekhodi okusebenza ngenhla. Kusistimu ehlukene, khomba ukulandelana kwe-elementi; ukuze uthole isikulufu socezu olulodwa, khomba izigaba zokusebenza emdwebeni ophelele. Ukulingana kwemishini nokusebenza okuxutshiwe kudinga ukuhlolwa okuhlukile kokwamukela.
Imibuzo ejwayelekile ukubuzwa
Ingabe ukuxuba okusabalalisa kungawaphula ama-pigment agglomerates?
Ukuxutshwa kokusabalalisa kusabalalisa kabusha impahla; akusho ngokwayo ukuthi ukucindezeleka okutholakalayo kwanele ukuphula i-agglomerate. Isici sangempela singanikela kuzo zombili izindlela zokuhlanganisa. Hlola ama-agglomerate ayinsalela ngokuhlukile kumbala noma ukufana kokwakheka ngaphambi kokunquma ukuthi kudingeka yini isenzo sokuhlakazeka okwengeziwe.
Ingabe ukukhulisa isivinini sesikulufa kuhlala kuthuthukisa ukuxubana?
Cha. Isivinini okokufaka kokusebenza, kuyilapho ukuxuba okwamukelekayo kuwumphumela womkhiqizo olinganisiwe. Qhathanisa ukuguqulwa kwesivinini nezimo zokudla, izinga lokushisa langempela lokuncibilika, umthwalo wokushayela kanye nokuhlolwa kwekhwalithi okuvunyelwene ngayo. Ungamukeli ukulungiselelwa kwe-rpm ephezulu uma izakhiwo zomkhiqizo ezidingekayo noma imikhawulo yokusebenza ingasafinyelelwa.
Ingabe amabhlogo okuxova angama-90 ahlala engcono kakhulu ekuhlakazweni?
Cha. I-engeli ye-Stagger ingukuhluka kwejometri eyodwa kuphela. Ububanzi bediski, ubude bebhulokhi obuphelele, isiqondiso sokudlulisa, izimo zokugcwalisa kanye nokucushwa okuzungezile nakho kudinga ukubuyekezwa. I-block engathathi hlangothi ingadlula izinto ngaphansi kwesenzo senqubo ezungezile; ukungathathi hlangothi akusho ukuthi okokusebenza kuhlala kumile.
Ingabe izakhi zokuxuba ezinamazinyo nazo zinganikeza ukuxuba okuhlakazekayo?
Yebo, kuye ngokuthi i-geometry nezimo zokusebenza. I-elementi echazwe njengengxube esakazayo isengakhiqiza izingcindezi zasendaweni. Cela ubufakazi bephrofayili yangempela nomsebenzi wempahla esikhundleni sokuphatha igama lesigaba njengencazelo ephelele yokusebenza kwalo.
Kungani imibala ingasala ngemva kokwengeza amabhlogo okuxova?
Amabhlokhi amaningi okuxova awaboni noma asuse imbangela ngokwawo. Hlola ukuqina komthamo, ifomu lesithako elingenayo, izimo zokuncibilika namasampuli aqoqwe ngaphansi kokusebenza okufanayo. Bese unquma ukuthi inkinga esele iwukusabalalisa kwendawo, ama-agglomerate angahlakazekile noma elinye iphutha ngaphambi kokwenza olunye ushintsho lokumisa.
Kusho ukuthini ukucushwa kwe-screw blade ku-twin-screw extrusion?
Kulo mhlahlandlela, ukucushwa okuwusizo kuyilungiselelo le-axial lokudlulisa, ukuxova kanye nokuxuba izingxenye, okubandakanya ubukhulu kanye nesiqondiso. Sebenzisa lawo magama athile emdwebeni. Ukubiza yonke inhlangano ngokuthi ukucushwa kwe-blade akucacisi imisebenzi yayo yokucubungula noma ukwenza amakhodi esici abahlinzeki abahlukahlukene ashintsheke.
