Analytical Analysis of a Pillar Crane for Handling of Sludge Pumps Breakdown

Abstract

: The article presents a technical description of a boom for handling sludge pumps. It is used in an object No. 900, a block V2 of the nuclear power plant in Jaslovské Bohunice. It is an object of a chemical water treatment plant belonging to the block V2. The boom is used at regular inspections of sludge pumps type 80 KD F150 9.5-A0-03 and for the needed handling with them during their operation. The boom of sludge pump designed for a load capacity of 120 kg was damaged during operation because the consequence of work the sludge pump was not considered during its design. This was causing a gradual accumulation of sludge around the suction openings of the pump. Therefore, the pump sometimes adhered to the bottom of the tank. In order to lift the pump thus adhered, it was subsequently necessary to apply approximately the four-times greater tensile force, for which the boom was no longer dimensioned. Therefore, it is important to optimize that state.
