Evaluation of energy efficiency of insertion-type peristalsis pump using pneumatic artificial muscles

The purpose of this study is to evaluate the energy efficiency of an insertion-type peristalsis pump and compare it with conventional methods such as the positive-displacement pump and rotodynamic pump. This device can transport high-viscosity fluids and solid-liquid-mixture fluids with low applied pressure in small spaces and various places such as the outdoors. In previous studies, the authors showed that this pump can transport water through a vertical pipe and a bent pipe. However, the performance of this devise has not been compared with that of conventional pumps. Thus, this paper evaluates the efficiency of the insertion-type peristalsis pump and has demonstrated that the insertion-type peristalsis pump has excellent energy efficiency.
