Spiral Conveyor
RUMUSAN: TWS = TB × FA
TWS dina Unit ieu hartina itungan tegangan conveyor spiral.
RUMUSAN: TB = [ 2 × RO × M + ( L1 + L2 ) ] ( WP + 2WB ) × FBW + ( WP × H )
RUMUSAN: TA = BS × FS × FT
Mangga tingal Table FT jeung Table FS.
Conto Praktis
Perbandingan TA sareng TB, sareng itungan anu aya hubunganana sami sareng jinis konveyor anu sanés.Aya larangan jeung peraturan tangtu dina rarancang jeung konstruksi tina conveyor spiral.Ku alatan éta, bari nerapkeun HONGSBELT spiral atawa péngkolan belts kana sistem conveyor spiral, kami nyarankeun Anjeun tingal manual Téknik HONGSBELT jeung kontak jeung departemén jasa teknis urang pikeun inpo nu salajengna jeung detil.
