GX-A-screw conveyor is a "screw conveyor" design and manufacturing standards according to JB / T7679-95, is the GX-screw conveyor replacement. Head and tail bearing housing to move outside, hanging bearings sliding bearings, set a dust-proof seal assembly, GX-A-screw conveyor 1. The diameter of the screw screw machine work series has the following seven: φ150 φ200 φ250 φ300 φ400 φ500 φ600 2. The following ten standard screw machine speed: n = 20, Length 30,35,45,60,75,90,120,150,190 (r / min) 3. screw machine from three meters until seventy meters only every half a meter a file, you can freely choose 4. For each the diameter of the screw conveyor, is depending on its power transmission feed amount, delivery of materials, conveyor length, conveying height and other factors over a wide range of changes, the values ??calculated using the following formula: (1) screw diameter D = KD: screw diameter in meters Y: material filling factor Q: throughput t / h r: material bulk density unit t / m 3 k: characteristic coefficient c: when the screw is inclined to work, delivery volume correction factor (2) spiral revolutions : n = n: limit the number of revolutions of the screw shaft in revolutions / meter A: Comprehensive feature coefficient B: screw diameter m (3) drives power No = h (WoL ± H) No pivot screw machine power required, kW h : select alternate coefficient between 1.2-1.4 Q: throughput t / h L: screw machine length m horizontal projection H: screw machine takes a positive sign when the vertical projection height meter transport up negative sign when you want to lower transport Wo: Material drag coefficient. Power screw driving device drives the overall efficiency of N = y = 0.94 http://www.hbchuchenqi.net/shusongshebeixilie/shusongji/
