Abstract:

This study is to evaluate the influence of some parameters in the centrifugal casting process on the performance of the received axial fan. It has been found that the quality of the surface state, material characteristics and blade design method has a great influence on the performance of the fan. The use of conventional centrifugal casting is an innovative innovation and is well suited for fabricating hollow-blade fans. With this method it is possible to reduce costs and fabricate relatively easily. In addition, the hollow characteristics of the fan give the fan many advantages, especially in the active control of the flow of losses on the blade tip position with the box housing and the ability to absorb sound. In this study, the material used was low-density polyethylene (LDPE). The parameters of the studied process include: powder mass (Polyethylene), temperature and heating time in the oven. For comparison, a fan with similar geometric dimensional parameters machined with the aluminum serves as a reference fan. Aerodynamic performance of fans tested on test bench standard ISO 5801. Analyses and comparisons are made based on the parameters selected for the fan fabrication process. The results show that the optimal choice of manufacturing process variables is necessary to achieve the desired mechanical performance for the fans fabricated by this technology.
