TY - JOUR AU1 - Dyuzhev, V. AB - UDC 621.928.3.004.1 V. G. Dyuzhev Normal operation of FVSh-35 (NVSh-350K) centrifuges requires precision settings of the clearances (depending on the feed stream) between the conveyor and the screen. The clearance is set by displacing the conveyor screw along the axis, and regulating the clearance by the number of turns of the M24� 1.5 lead screw. The bowl with the screen mounted on it experiences no axial displacement. The thread in the screw-nut threaded pair wears out eventually because of frequent replacements of the screens, repair operations, etc., and the profile and pitch of the thread change, the screw black- lash increases, and it becomes impossible to set the clearances precisely in terms of the number of lead screw rotations. Practice has shown that even a 0.2 to 0.25 mm deviation in the clearance will have adverse effects: wedging of the centrifuge bowl, damage to the screens, and sometines (should the interlock fail to function) even twisting of the bowl shaft, when the clearance is on the narrow side of the tolerance; also, the screen service life can be shortened from the rated 300 h to 100 h or less when used on an ammonium sulfate stream; and the product TI - Control of clearances in the FVSH-35 centrifuges JF - Chemical and Petroleum Engineering DO - 10.1007/BF01877091 DA - 2005-05-31 UR - https://www.deepdyve.com/lp/springer-journals/control-of-clearances-in-the-fvsh-35-centrifuges-a6Shs3lZSy SP - 483 EP - 484 VL - 8 IS - 5 DP - DeepDyve ER -
