ezinye izixazululo mayelana nesikulufu somshini wokubumba umjovo

Isebenza kanjani umjovo udini umshini screw isiliphu somsindo esingavamile ukwenza

Uma isikulufu siqala ukushelela phakathi nesigaba sokulungisa, ukunyakaza kwe-axial yesikulufu kuyama njengoba isikulufu siqhubeka nokuzungezisa. Ngokuvamile isiliphu sesikulufa sizoholela ekonakaleni kwezinto ngaphambi kokubunjwa komjovo.kodwa futhi nesibhamu esifushane, umjikelezo wokucubungula owandisiwe nezinye izinkinga zekhwalithi yomkhiqizo.
Umthelela wamapharamitha wenqubo
Izinga lokushisa eliphansi elingemuva komgqomo ngokuvamile liyimbangela eyinhloko yokushelela kwesikulufu somjovo wepulasitiki. Umgqomo womshini wokubumba umjovo uhlukaniswe izigaba ezintathu. Ngemuva kwesigaba sokuphakelayo, ungqimba oluncane lwe-polymer encibilikisiwe lwakhiwa ngesikhathi sokushisa nokucindezelwa kwezinto. Isendlalelo sefilimu esincibilikisiwe sinamathele emgqonyeni. Ngaphandle kwalolu ungqimba oluncane, kungaba nzima ukuhambisa ama-pellets phambili. Izinto ezisesigabeni sokuphakelayo kumele zishiswe zifike endaweni ebucayi ukuze kukhiqizwe ifilimu encibilikisiwe ebalulekile. Noma kunjalo, kuvame ukuthi into ngesikhathi sokugcinwa kwemigqomo ibe mfishane kakhulu ukuze ipholimeri ikwazi ukufinyelela leli zinga lokushisa. Lesi simo kungenzeka ngenxa yokuthi imishini mincane kakhulu, ukucushwa okuhambisanayo komgqomo omncane nesikulufu okudalwe.
Isikhathi sokuhlala esifushane kakhulu singabangela ukuncibilika kwe-polymer noma ukuxutshwa okwanele, okuzoholela ekusheleleni ngezikulufu noma ukuma. Nazi izindlela ezimbili ezilula zokubhekana nale nkinga. Inani elincane lezinto zengezwa kusukela ekupheleni komgqomo wokuhlanza futhi izinga lokushisa elincibilikayo liyahlolwa. Uma isikhathi sokuhlala sifushane, izinga lokushisa elincibilikayo lizoba ngaphansi kwenani elibekiwe lokushisa komgqomo. Indlela yesibili ukubheka umkhiqizo osuphelile futhi uma kutholakala ukuthi unemabula, enamabala amnyama noma anemithende ekhanyayo, kukhombisa ukuthi impahla ayixubene kahle emgqonyeni.
Umthelela wemishini

Uma imbangela yokushelela kwesikulufu kubangelwe ukucubungula okokusebenza kunokucubungula amapharamitha, khona-ke ukuguga kwesikulufa nomgqomo kungenzeka kube inkinga eyinhloko. Njengengxenye yokudla, lapho i-resin incibilika esigabeni sokucindezelwa kwesikulufa, inamathela odongeni lwesilinda. Lapho isikulufu sizungeziswa, impahla igundwa kude nodonga lwesilinda futhi ihanjiswe phambili. Uma kunezindawo zokuguga esikulukweni nasemgqonyeni, khona-ke isikulufu asikwazi ukudlulisa ngempumelelo ukulethwa kwezinto. Uma kusolwa ukugqoka, isikulufu nomgqomo kufanele kuhlolwe futhi imvume efanelekile phakathi kwakho kokubili kufanele ihlolwe. Uma isikulufu nomgqomo imvume inenani elingaphezu kwenani elijwayelekile, kufanele iqale ukushintsha noma ukulungisa umsebenzi. Ukwehluleka kweringi yesheke (hlola i-valve) kungabangela futhi ukuthi isikulufu sishelele. Lapho isikulufu sizungeziswa futhi senziwe ngepulasitiki, iringi engemuva kufanele ibe ngaphambili (vula) indawo kanye nokuxhumana nesihlalo sendandatho yokulungisa. Uma i-Stop Ring ingemuva (ivaliwe) isimo, noma phakathi kwendawo eya phambili neyokubuyela emuva, i-polymer encibilikisiwe izoba namandla okumelana nokudlula igebe phakathi kwe-Stop Ring nesihlalo esiyindandatho.
Uma kunokungabaza nge-Stop Ring, buyisela ngokushesha. I-resin feed hopper ingaba yimbangela yokushelela ezinhlobonhlobo zezikulufu zokubumba umjovo. Idizayini ye-hopper elungile iwukhiye wokuqinisekisa ukulethwa okuzinzile kwezinto, kodwa lokhu kuvame ukunganakwa. Ngenjwayelo, ama-pellets amasha osayizi ofanayo asebenza kahle ku-hopper yesikwele enendawo yokucindezela okungazelelwe (ngokuncipha okungazelelwe phansi) . Noma kunjalo, akunjalo uma izinto ezigaywe kabusha zengezwa. Ukuma nobukhulu bama-pellets kuhluke kakhulu ngemva kokuchotshozwa futhi, okuzothinta ukufana kokuphakelayo. Ukondla okungahambisani kusho ukuthi isikulufu asikwazi ukugcina ingcindezi yokudla efanayo ku-Melt, okuholela eqhweni. Ukuze uxazulule le nkinga futhi uxazulule umehluko wosayizi phakathi kwezinto ezigaywe kabusha kanye nezinto ezintsha, singazama ukusebenzisa i-round hopper enendawo yokucindezela eyisicaba (ngegradient eyisicaba phansi) .

1.Indawo yeringi ye-hydraulic yokuvula isikhunta incane kakhulu
Amandla okuvula isikhunta = isikhunta sokuvula i-oil pressure pressure ring area × isikhunta sokuvula ingcindezi kawoyela
Uma ufuna ukwandisa amandla okuvula isikhunta lapho ukucindezela okukhulu kunqunywa, ungakwazi kuphela ukwandisa isikhunta ukuvulwa uwoyela ingcindezi ring indawo, futhi ungakwazi ukwandisa indawo yokucindezela uwoyela yokuvula isikhunta ngokwandisa ububanzi besilinda noma ukunciphisa ububanzi benduku yepiston..
