A1 txujci txoj cai
Txoj kev siv lub pob alumina hauv lub taub dej ntawm polyurethane kom poob siab thiab zom raws li cov kev cai tswjhwm, thiab kuaj cov khoom ntawm lub pob, kom qhov txhav tsis kam ntawm lub npas alumina yog qhia hauv chav tsev.
A2 sib tsoo cov kaus poom
Lub tank yog tsim los ntawm polyurethane. Sab hauv kab 200 hli, ntev 220mm
A3 txhuam kuj raug kev sim tshuab
Lub A2 tuaj yeem muab nrog 4kg alumina pob thiab 4L dej tank nrog 80r / min khiav mus tas li.
A4 xeem npaj
Qhov zoo thiab cov tsos ntawm alumina npas kuaj txog 4kg, loaded rau hauv A2 cov kaus poom, ntxiv rau 4L kais dej, hauv qhov kev sib tw khoom siv tshuab, nrog 80r / min sib tsoo 2h. Nqa tawm cov qauv thiab ntxuav nws nrog dej.
A5 xeem txoj kev
A5.1 tom qab kuaj cov kab mob A4, nrog lub siab ntawm qhov ntau ntawm 0.1g teev uas m1;
A5.2 cov qauv saum toj no yog muab tso rau hauv lub A2 sib tsoo tank, nrog tib qhov hnyav ntawm dej. Tom qab sib khi, cov dej yuav tsum tsis txhob ntuav, thiab muab tso rau ntawm lub tshuab ua kom tsis muaj teeb meem, kom lub pob zeb sib tsoo yuav tsum nres tom qab 80r / min sib tsoo thiab 24 teev.
A5.3 tshem tawm cov qauv ntawm lub zeb thiab ntxuav nws nrog dej. Nws cem M2 tom qab so qhuav.
A5.4 ntsuas qhov nruab nrab inch ntawm 10 npas raws li cov cai D.
A6 tau qhia
Los ntawm kev cuam tshuam cov kev puas tsuaj thiab kev puas tsuaj, tsis muaj kev nrawm, tsis tawg, raws li kev poob siab tsis muaj peev xwm.
