| Summary: | Paradigm of electric energy generator systems today is a distributed system, the number of small-scale plants are built and connected to the power grid locally and nationally. In a small-scale electricity generator, steam turbine radial inflow is suitable to be applied because it is low-cost. The most important thing on the performance of turbine is the blade shape of the turbine impeller. One of the impellers blade that is suitable to use in radial inflow turbines is impeller of turbocharger. Therefore, this research focused on making construction of a radial inflow steam turbine based on turbocharger impeller and process planning of it. The technical feasibility of this turbine was considered on manufacturability and assembly ability. The methods of this research was reviewing of the blade modeling based on turbocharger impeller; electoral materials for nozzle and turbine housing and the selection of other supporting components, such as shafts, bearings, and lubrication systems; and the process planning was based on the manufacturability and assembly ability. Manufacturing and assembling analysis was done by using DFMA method (design for manufacturing and assembling). The results of this research was the documentation of assembly drawings and part drawings for radial inflow steam turbine, process planning of the nozzle, stator, and rotor components that were made with the best possible and the fastest of manufacturing. Assembling time estimation was generated by using Boothroyd-Dewhurst table which it was 385.7 seconds, and it gained 7% for design efficiency. Meanwhile, the estimated time for making rear casing parts with the nozzle was 170 minute, front casing with diffuser was 226.1 minute, and rotor was 378.4 minute. |
