An Effective Impeller Design for Pump

Abstract

The impeller of a centrifugal pump plays an important role because it determining the flow rate and efficiency of the pump. The efficiency of the pump is determined by the design of the impeller design. Under filing is one of the method for removing material from the underside of the impeller vane at the exit. Under filing also increases the pump head. The design involves having a blade height that is lower than the nominal impeller diameter, which can lead to reduced power consumption, improved flow characteristics, and decreased noise and vibration compared to traditional impellers. The design of under filing impeller vanes can be optimized by various parameters, such as the blade angle, blade thickness, and number of vanes. Computational fluid dynamics (CFD) simulations and experimental testing can be used to optimise the design and ensure proper performance. The modified impeller should then be installed in a test rig that replicates the operating conditions of the pump or compressor. The test rig should be equipped with suitable sensors to measure flow rate, pressure, temperature, and power consumption. The performance of the modified impeller should be compared to that of the baseline impeller, and the improvement in efficiency should be quantified.
