TROUBLE SHOOTING OF RAW MATERIAL HANDLING IN BAGASSE PULPING

Abstract

The agitator bearing and shaft bending due to foreign materials is reduced by using stuffing box in the agitator between bearing unit and impeller. The foreign materials in the bagasse wet washing are collected by using SS Pivot Needles/Bars in the wet washing system. The vibrations which cause damage (cracks) in the pump pipe line are reduced by using rubber bellow between the pump and delivery pipeline. The rubber bellow absorbs the vibration and deflections due to vibration which protects the pump and pipeline from damages. Earlier the foreign materials were struck up in the pump impeller. These foreign materials were removed by dismantling the entire pump set up. In the current work, the design of suction line was altered by introducing an inspection dummy. At the end of the suction line, through the new design the foreign materials were moved off from the pump impeller easily by removing the inspection dummy instead of dismantling the entire pump set up. Through the new design, the efficiency of the wet washing plant is increased upto 55%. Further, the downtime of wet washing plant also reduced and availability of equipment is increased.
