2. Amandla ovavanyo oluqhelekileyo (inqanaba lesibhozo)
Inqanaba 1: 0.325 kg = (intonga yepiston + ubunzima betreyi + umkhono wokugquma ubushushu + 1 umzimba wobunzima)
=3.187N
Inqanaba 2: 1.200 kg=(0.325+0.875 ubunzima No. 2)=11.77 N
Inqanaba 3: 2.160 kg = (0.325 + No. 3 1.835 ubunzima) = 21.18 N
Inqanaba 4: 3.800 kg=(0.325+No. 4 3.475 ubunzima)=37.26 N
Inqanaba 5: 5.000 kg = (0.325 + No. 5 4.675 ubunzima) = 49.03 N
Inqanaba 6: 10.000 kg = (0.325 + No. 5 4.675 ubunzima + No. 6 5.000 ubunzima) = 98.07 N
Inqanaba 7: 12.000 kg=(0.325+No. 5 4.675 ubunzima+No. 6 5.000+No. 7 2.500 ubunzima)=122.58 N
Inqanaba 8: 21.600 kg=(0.325+No. 2 0.875 ubunzima+No. 3 1.835+No. 4
3.475+No.5 4.675+No.6 5.000+No.7 2.500+No.8 2.915 weight)=211.82 N
Impazamo enxulumene nobunzima bobunzima ngu-≤0.5%.

3. Uluhlu lobushushu:50-300℃
4. Ukuchaneka rhoqo kobushushu:±0.5℃.
5. Ubonelelo lwamandla:220V±10% 50Hz
6. Iimeko zendawo yokusebenza:iqondo lobushushu kwindawo yi-10℃-40℃; ukufuma okunxulumene nokusingqongileyo yi-30%-80%; akukho ndawo ingcolisayo, akukho moya unamandla; akukho kungcangcazela ngeenxa zonke, akukho luphazamiseko lunamandla lwemagnethi.
7. Imilinganiselo yangaphandle yesixhobo: 250×350×600=(ubude×ububanzi×ubude)
Ubume kunye nomgaqo wokusebenza:
I-DRK208 yokuvavanya izinga lokunyibilika lokunyibilika yimitha yeplastiki ekhutshiweyo. Isebenzisa isithando somlilo esiphezulu sokushisa ukwenza into elinganisiweyo ifikelele kwisimo esityhidiweyo phantsi kwemeko yokushisa echaziweyo. Into yovavanyo kule meko etyhidiweyo iphantsi kovavanyo lwe-extrusion ngokusebenzisa umngxuma omncinci wobubanzi obuthile phantsi kobunzima bomthwalo wobunzima obumiselweyo. Kwimveliso yeplastiki yamashishini amashishini kunye nophando lweeyunithi zophando lwezenzululwazi, "isantya sokunyibilika (ubuninzi) sokuhamba" sihlala sisetyenziselwa ukuvakalisa iimpawu ezibonakalayo zezinto zepolymer kwimeko etyhidiweyo njenge-fluidity kunye ne-viscosity. Into ebizwa ngokuba yi-melt index ibhekisela kubunzima obuqhelekileyo becandelo ngalinye le-extrudate eliguqulelwe kumthamo we-extrusion wemizuzu eyi-10.
Imitha yesantya sokunyibilika (ubunzima) ibonakaliswa yi-MFR, iyunithi yile: iigram/10 imizuzu (g/min), kwaye ifomula ibonakaliswa ngu: MFR (θ, mnom)
=tref .m/t
Kwifomula: θ—— uvavanyo lobushushu
mnum- umthwalo oqhelekileyo Kg
m —— ubunzima obuqhelekileyo bokusikwa g
tref —— ixesha lokubhekisela (10min), S (600s)
t —— ukunqunyulwa kwesithuba sexesha s
Esi sixhobo siqulunqwe kwisithando somlilo kunye nenkqubo yokulawula ukushisa kwaye ifakwe kwisiseko somzimba (ikholomu).
Inxalenye yolawulo lobushushu ithatha i-single-chip microcomputer amandla kunye nendlela yokulawula ubushushu, enekhono elinamandla lokuchasana nokuphazamiseka, ukuchaneka kokulawula ubushushu obuphezulu, kunye nolawulo oluzinzileyo. Intambo yokufudumeza kwisithando somlilo inxeba kwintonga yokufudumala ngokomgaqo othile wokunciphisa i-gradient yeqondo lokushisa ukuhlangabezana neemfuno eziqhelekileyo.

Ukulumkela:
1. Isokethi yamandla enye kufuneka ibe nomngxuma wokumisa kwaye isekelwe ngokuthembekileyo.
2. Ukuba umboniso ongaqhelekanga uvela kwi-LCD, yicime kuqala, uze usethe kwakhona ubushushu bokuvavanya emva kokuyivula, kwaye uqale umsebenzi.
3. Ngethuba lokusebenza okuqhelekileyo, ukuba ukushisa kwesithando somlilo kungaphezulu kwe-300 ° C, isofthiwe iya kuyikhusela, iphazamise ukufudumeza, kwaye ithumele i-alamu.
4. Ukuba kwenzeka into engaqhelekanga, njengokuba iqondo lokushisa alikwazi ukulawulwa okanye ukuboniswa, njl., kufuneka livalwe kwaye lilungiswe.
5. Xa uhlambulula intonga yepiston, musa ukukrazula ngezinto ezinzima.

Qaphela: Ngenxa yenkqubela phambili yezobuchwepheshe, ulwazi luya kutshintshwa ngaphandle kwesaziso. Imveliso ixhomekeke kwimveliso yokwenene kwixesha elizayo.
