Abstract

The squeezing and releasing mechanism is used to transport the fluid from lower to higher pressure in peristaltic pump tube with rollers, which causes contraction & expansion along the flexible tube. So the significant influenced parameter on peristaltic pump is the roller diameter and roller material which improves the life of the tube. Hence, the present research is focused on the fabrication of rollers using the polymer matrix composites in injection moulding process by varying the percentage of reinforcement materials i.e. ceramics particles such as, 2%, 4%, 6%, 8% and 10% of silicon carbide and fly ash. These composites are tested for strength and hardness using Charpy Impact and Rockwell Hardness testing machines. Finally, the combination with which the material is having superior mechanical properties is chosen from the experimental data. The new PMC roller fabricated with this combination is used in peristaltic pump for squeezing and releasing Mechanism.
