Eccentric shafts - Import export

If there is axial misalignment (eccentricity) between the drive shaft and the shaft of a potentiometer used to sense angular, motion, this will cause a linearity error that increases as the coupling radius decreases in relation to the degree of eccentricity. The following equation determines the maximum relative error Fmax = E/Pi · rk where E = Eccentricity und rk = the coupling radius. It is only possible to take full advantage of the linearity or conformity of any rotationary sensor system, if coupling alignment errors (offset and angular misalignment) are avoided or at least reduced to a mimimum. This means that with highly accurate measurement systems, due allowance must be made for any coupling misalingment in accordance with the above equation.

Eccentric screw pump tube HD-E Industryfor oils, paints and disposal liquids is available in the food version (Pure) The HD-E Eccentric screw pump in the industrial version transfers the advantages of the Drum pump low-viscosity media quite simply to the medium-viscosity range. The positive displacement pump has an easily detachable outer tube, a bearing head with mechanical seal and a free-running shaft with an eccentric screw as the pumping element - all easy to dismantle and clean. The Pump tube can be suitably combined with our single-phase motor. This ensures the draining of liquids and thus saves important resources. * also available in special immersion depths * Pump tube equipped with Lutz original hand wheel * Media examples: Oils, waste oils, disposal liquids, paints. * Smooth running * Uniform volume flow * Gentle, low-pulsation product conveying * Low wear * Easily detachable outer tube
