Ukuthuthukiswa okusheshayo kwemboni yezindlu ezithengiswayo kuye kwaholela ekuchumeni kwezimboni ze-ceramic kanye nezinkuni. Kodwa-ke, indawo yokukhiqiza nokucubungula i-ceramics ingcoliswe kakhulu, futhi ukutshalwa kwezimali okukhulu kwezinkuni kuye kwaholela ekwehleni okukhulu kokutshalwa kwehlathi. Ngokuqwashisa okwandayo kokuvikelwa kwemvelo kwabantu, imikhiqizo eminingi yezinto ezibonakalayo iye yavela. Umshini wokwenza ukhuni esiFundazweni sase-Guangde, eSifundazweni sase-Anhui wamukela ibhodi lepulasitiki le-polyethylene eliphansi elinegwebu elincane, elinezinzuzo zamandla amakhulu emishini, ukusebenza kahle kokubhafa, ukuguquguquka okuqinile kwezinga lokushisa, nokumelana nemisebe. Kodwa ithambekele ekushintsheni ekukhiqizeni nasekucubunguleni inqubo, futhi idinga amazinga aphezulu okuphrinta. Ngakho-ke, kunezidingo eziphakeme kakhulu zengxenye yokushayela. Lesi sihloko sichaza ukusetshenziswa kwesiguquli sefrikhwensi yochungechunge lwe-Dongli Kechuang CT1 emkhakheni, futhi sichaza kabanzi ngohlelo lwesicelo luka-Dongli Kechuang embonini yomshini wokudonsa ngokhuni.
Isingeniso Sesimiso Sokulawula Ugesi Womshini Wokudonsa I-Plate
Ukwakhiwa kwesistimu yokulawula kagesi yomshini wokuqopha we-CNC
Isingeniso Somsebenzi Womshini Wokudonsa: Umsebenzi womshini wokudonsa ibhodi ukukhiqiza amabhodi epulasitiki anogqinsi olungaguquki, ububanzi obugxilile, nokuphrinta okukhethekile. Ngemuva kokuthi ibhodi lenziwe, lisetshenziselwa ukwakhiwa kwezindlu zangempela. Ingxenye yokuqala yokucutshungulwa i-extruder yepulasitiki, exuba izinto ezingavuthiwe futhi izenze zibe yizimo ze-thermoplastic ngaphambi kokuzikhipha. Indlela yokudonsa ishidi ikhipha ishidi elikhishiwe. Kodwa-ke, ngenxa yokukhishwa kwempahla engalingani kusuka ku-extruder engaphambili, kungase kubangele ukuthi amanye amashidi abe banzi futhi amanye abe mancane. Ngakho-ke, inzwa yendawo idinga ukufakwa ukuze uthole impendulo yesignali yobubanzi.
Izimfuneko zokulawula
1. I-torque ephezulu ye-low-frequency kanye nokunemba kokuzinza kwesivinini esikhulu: Ngenxa yokuthi isivinini sokusebenza sangempela asiphezulu, kuyadingeka ukuqinisekisa ukukhishwa kwe-torque njalo, ngisho nangesivinini esiphansi, ukuqinisekisa ukukhishwa okukhulu; Kudingekile ukuqinisekisa ukuthi ubukhulu bebhodi buhambisana, ngakho-ke ukunemba kokuqina kwesivinini kufanele kube phezulu, ngaphandle kwalokho kuzoholela ekugqineni okungalingani kwebhodi.
2. Ukulawula ukuma kobubanzi: Kuyadingeka ukuqinisekisa ububanzi obungaguquki, ngakho-ke ukuma kobubanzi kuyadingeka. Ulwazi lwendawo lungathathwa ngezinzwa zokuma njengempendulo yesignali yobubanzi bebhodi. Isiguquli sefrikhwensi sinquma ukuthi sikhulise noma sinciphise isivinini ngokuthola amasiginali obubanzi ukuze siqonde inani lamanje lezinto ezingenayo.
3. Isethingi yefrikhwensi eyinhlanganisela: Ezimweni eziningi, isivinini esijwayelekile singahlangabezana nezidingo, ngakho-ke isilungiselelo sefrikhwensi esiyisisekelo nesifanele sidinga ukunikezwa. Kwesinye isikhathi, izinto ezingenayo ezingalingani zidinga ukulungiswa kwemvamisa. Isiguquli sefrikhwensi sikhipha imvamisa eyinhlanganisela ngokulungiswa kwe-PID, futhi imvamisa ebekwe ngaphezulu iqinisekisa impendulo kulwazi lwamanje lobubanzi, iqinisekisa ukusabela okusheshayo noma kwenzeka kuba nokungajwayelekile kwezinto.
4. Ukulungiswa kwemvamisa okulawulekayo: Ukulungiswa kwesivinini esinensayo kungaholela ekuphenduleni kwesistimu okunensayo kanye nobukhulu obungalingani bebhodi; Ukulungisa isivinini ngokushesha kakhulu kungabangela ukushintshashintsha okukhulu kwesivinini esijikelezayo kanye nendawo yokuphrinta engalingani. Ngakho-ke, imvamisa ye-superposition idinga ukukhawulwa ngomkhawulo ophansi.
Indlela yokuqala yokumisa isiguquli se-frequency i-terminal start stop, okusho ukuthi umyalo we-DI1/DI unikezwa isiguquli sefrikhwensi ngenkinobho yangaphandle ngokusebenzisa itheminali yokufaka yedijithali ukuze kuzuzwe ukuma kokuqala kwenjini.
Uma kucatshangelwa ukuthi ukubhuleka ngokushesha kungase kudingeke uma uhlelo lwezimo eziphuthumayo luhluleka ukugwema ukulimala komshini, umsebenzi wokumisa izimo eziphuthumayo uqaliswa nge-DI3 njengetheminali. Isignali yephutha yesiguquli sefrikhwensi iphuma ngetheminali yokudlulisela imvamisa ehlelekayo, futhi isistimu ithola isignali yephutha ukugwema ukulimala komshini okubangelwa ukungasebenzisi kahle lapho isiguquli sefrikhwensi sihluleka. Ngemuva kokuthi iphutha selisuliwe, ilokhi yephutha ingakhululwa ngetheminali yokusetha kabusha.
Ngenxa yokuthi isistimu isebenzisa inhlanganisela yemithombo emibili yemvamisa, kungase kube khona ukungazinzi phakathi nenqubo yokuhlola. Ngakho-ke, inkinobho yesenzo esisodwa yengeziwe, engasetshenziswa ukushintsha umthombo wemvamisa phakathi nemodi yokulungisa iphutha ngokusebenzisa inkinobho eyodwa yesenzo.
Indlela yokulawula isivinini sesistimu iyinhlanganisela yezinhlanganisela ezimbili zefrikhwensi, isilungiselelo esiyinhloko sinikezwa ikhibhodi, isilungiselelo sesibili sinikezwa i-PID, kanye nesilungiselelo sesibili sinikezwa inani elincane lokulungiswa. Kungasethwa umkhawulo omncane ophezulu naphansi.
Incazelo yephuzu elingukhiye: Njengoba isivinini somshini wokuphakela ongaphambili singashintshi, inani lokulungiswa kwengxenye eyisizayo yokulungisa akudingeki libe likhulu kakhulu. Uma ukulungiswa kwefrikhwensi yokusiza kukuncane kakhulu, impendulo yesiginali yesikhundla izohamba kancane, okuzoholela ebubanzini obungalingani bebhodi nobukhulu; Uma ifrikhwensi yokulungisa eyisiza iphezulu kakhulu futhi isivinini sishintsha kakhulu ngesikhathi seyunithi ngayinye, izobangela ukuphrinta okungavamile ebhodini, okuholela kumaphethini ajulile noma angajulile. Ngakho-ke, imikhawulo engaphezulu nephansi yokulungiswa kwe-PID idinga ukusethwa ngokufanele.
