Inkqubo yokusebenza kunye nezilumkiso zokusebenza kwe-twin-screw foam granulator

Izixhobo zidlula kwizibuko lokutyisa leigwebu le-twin-screwigranulator. Ngaphantsi kwesenzo sezikrini ezijikelezayo, zifakwe kwiibhola kwaye ziqhubele phambili kunye ne-screw grooves. Ngenxa yokucheba, ukunyanzeliswa kunye nemiphumo evuselelayo ye-screws, izixhobo zixutywa ngakumbi kwaye zenziwe ngeplastiki, kunye nobushushu kunye noxinzelelo olunyuka ngokuthe ngcembe, lubonisa ukugeleza kwe-viscous. Emva koko badlula kwintloko yokufa ngoxinzelelo oluthile kunye nobushushu, kwaye ekugqibeleni iimveliso zemilo efunekayo zifunyenwe.

Imigqaliselo yokusebenza kweyunithi ephambili yei-i-twin-screw foam granulator

1. Umjelo olinganisiweyo weyunithi ephambili ngumbane olinganisiweyo wemoto. Ngethuba lokusebenza okuqhelekileyo, kufuneka ilawulwe ngaphantsi kwe-80% ye-current rated current, ishiya i-leeway ethile yokuthintela ukugqithiswa (nceda ubhekisele kwi-motor nameplate ye-current rated current). I-voltage elinganisiweyo kunye ne-frequency yeyunithi ephambili kufuneka ilawulwe ngaphezu kwe-50% ye-voltage kunye ne-frequency ngexesha lokusebenza okuqhelekileyo.

2. Inzwa yoxinzelelo lwentloko ixhotyiswe ngemitha yokubonisa idijithali. Umsebenzi oqhelekileyo wokuboniswa kwedijithali kufuneka ube ngaphantsi kwe-10MPa. Umsebenzisi kufuneka ebeke iliso rhoqo umboniso wedijithali. Ukuba ingaphezulu kwe-15MPa, kufuneka bajonge ukuba ijelo lokuhamba livaliwe na. Ukutya kufuneka kumiswe ngokukhawuleza, kwaye isantya se-screw somatshini oyintloko kufuneka sincitshiswe ngokuthe ngcembe ukulungelelanisa umboniso wedijithali kwi-sensor ukuya ngaphantsi kwe-10MPa. Ukuba umboniso wedijithali uhlala uphezulu, Umatshini kufuneka uvalwe ngesandla ukuze uhlolwe.

3. Abaqhubi kufuneka bajonge rhoqo umsila wokuthambisa i-oyile yokulinganisa uxinzelelo (ixabiso ngu-0.1-0.2MPa). Ukuba ungaphantsi kwe-0.05MPa, umatshini kufuneka umiswe ngokukhawuleza ukuze uhlole isekethe yeoli, i-oyile yempompo ye-oyile kunye nempompo yeoli, ukuze kukhuselwe ukusebenza okuqhelekileyo kweegiya zebhokisi zothumelo.

4. Xa kukusebenza okuqhelekileyo, kufuneka kubekho iirekhodi zokusebenza.
