Iziphi izici ezithinta ukubumba kwe-extuder epulasitiki? - I-Suzhou PolyTime imishini ye-co, Ltd.

Amapharamitha aphambili athinta inqubo yokukhishwa kwepulasitiki ye-extruder yepulasitiki yizinga lokushisa, ingcindezi, kanye nesilinganiso sokukhishwa. Izinga lokushisa liyisimo esibalulekile senqubo ebushelelezi yokukhishwa. Lapho okuqukethwe kufakwe uprimule emgqonyeni, izinga lokushisa laso ngeke libe ngaphansi kwezinga lokushisa layo lokugeleza, ngenye indlela, inqubo yokukhishwa izothinteka, ikhwalithi ngeke ibe phezulu kakhulu. Izinga lokushisa eliphakeme kakhulu lizodala ukusabela kwepulasitiki, okuphumela ekubhujisweni kwesakhiwo sepulasitiki futhi ngeke kusetshenziswe. Ngakho-ke, ngokuvamile, amazinga okushisa athuthukile kufanele akhethe inani elifanele phakathi kokushisa kwe-viscous flow kanye nokushisa okuvumayo.

Nalu uhlu lokuqukethwe:

Yiziphi izici zokulawulwa kokushisa kwe-plastic extruder?

Yiziphi izidingo zenqubo ye-plastic extruder?

Yiziphi izici zokulawulwa kokushisa kwe-plastic extruder?
Njengolunye uhlobo oluhluke kakhulu olulawulwa ohlelweni lokulawula inqubo, izici zokushisa zento elawulwa zibonisa ukufana okuthile. Okokuqala, izimo zokusebenza ezizinzile zento ziboniswa esele phakathi kokungena kwamanzi nokuphuma kokushisa ngaphakathi kwento. Uma inqubo idinga ukuthi inani lokushisa ligcinwe ngenani elibekiwe, uhlelo kufanele lulawule ukungena nokuphuma kokushisa nganoma yisiphi isikhathi, okungukuthi, ukufudumeza nokupholisa. Okwesibili, ngenxa yesilinganiso esikhulu sokugcina sento elawulwa, izinga lokushisa lishintsha kancane futhi isilinganiselo sesikhathi sesikhathi eside, imvamisa imizuzu embalwa noma amaminithi. Okwesithathu, iningi lezinhlelo zinosizi lokubambezeleka kokudlulisela, okuholela ekubambezelweni okuhlanzekile ezicini zokushisa zento elawulwa.

Ngaphezu kwezimpawu zokulawulwa kokushisa okujwayelekile, ukulawulwa kokushisa komshini we-extruder nakho kunokwenziwa kwawo, okubonakala ikakhulu kulezi zinto ezilandelayo.

1. Isikhathi njalo sikhulu, futhi ukubambezeleka okuhlanzekile kunde kakhulu.

2. Ukuhlanganiswa okuqinile phakathi kwezindawo zokulawula izinga lokushisa.

3. Ukuphazanyiswa okunamandla.

Due to the influence of the above factors, the plastic extruder temperature system has the characteristics of large time scale, high nonlinearity, and strong dynamic mutation, which makes the control complex.

Yiziphi izidingo zenqubo ye-plastic extruder?
Isidingo sokushisa senqubo yokukhishwa yinkomba yokusebenza yohlelo lokulawula lokushisa. Lezi zinkomba zigxile ekuqineni, ukunemba, kanye nokushesha kohlelo. Ngokwamahluko wenqubo yenqubo yokusebenza, ihlukaniswe ngezigaba ezimbili: I-Static Index kanye ne-Static Index, kubandakanya nezinto ezilandelayo.

1. Ukulinganisa Ukulahla kokushisa

Ukunemba kokulawulwa kokushisa kuyindinganiso eyinhloko yokulawulwa kokushisa okuphezulu. Kuboniswa umehluko phakathi kwenani lokushisa langempela nenani elisethiwe lapho i-extruder isesimweni esijwayelekile sokukhishwa. Umahluko omncane uwukuthi, kukhuphuka kakhulu ukunemba. Ukuphambuka kungathathwa njengokuphambuka okuqinile kohlelo, futhi le nkomba ikhombisa ukunemba kohlelo lokulawula.

2. Isikhathi sokushisa

Isikhathi sokushisa sokushisa singenye yezinkomba eziguqukayo zohlelo, olukhombisa ukushesha kohlelo. Isikhathi sokushisa ikakhulukazi isidingo sokushiswa komphakathi. Esigabeni se-Preheating of the extredher, izinga lokushisa lodonga lwangaphakathi lomgqomo ludinga ukukhuphuka kusuka ekushiseni kwamakamelo kuya ekushiseni okunqunywe kusengaphambili. Ngenxa yokuphambuka okukhulu, isikhathi sokushisa singaba yinde kakhulu.

3. Ukushisa okuphezulu ngokweqile

Ukuze sinciphise isikhathi sokulawulwa kohlelo, kuvame ukudingeka ukwandisa ukuphuma kokushisa kwensiza yokushisa, engadala i-osshoot enkulu ye-overshoot kanye ne-osshoot oscillation yohlelo. Ngakho-ke, uhlelo lokulawula lokushisa lomshini we-extreder kufanele lizame ukugwema ukweqisa okukhulu, futhi sihlabele isikhathi esithile sokulungiswa lapho kunesidingo, ukuqinisekisa ukuthi uhlelo alunayo i-oscillation enkulu.

Ukushisa kudlala indima enqumayo ekukhishweni kweplastiki futhi kuyisici esibalulekile senqubo yokukhishwa. Ngakho-ke, kudingeka kakhulu ukulawula izinga lokushisa elisebenzayo le-plastic extuders ngaphakathi kwenqubo efanelekile yenqubo. I-Suzhou PolyTime machchmit co, Ltd izibophezele ekuthuthukiseni ikhwalithi yempilo yomuntu. Ngemizamo eqhubekayo ekuthuthukisweni kobuchwepheshe kanye nokulawulwa kwekhwalithi yomkhiqizo, sekuphenduke amabhizinisi ajwayelekile aphesheya. Uma ubandakanyeka emsebenzini ohlobene nepulasitiki, ungabheka imikhiqizo yethu esebenza kahle.
