Effect of Silencing Groove in Valve Plate on Efficiency of Radial Piston Pump

The recent trend is harvesting more efficient radial piston pumps for industrial applications. The valve plate geometry of the pump plays a crucial role in yielding the pump pressure and flow as a whole generated output power of the pump. The generated output power of the pump is dependent on pump pressure and flow rate, the required input power of the pump is liable to rotational torque and speed. This simulation study designed the valve plate geometry with and without silencing groove and analysed the pump performance, forces, required input mechanical power and generated output fluid power. The silencing groove valve plate plays a vital role in pump performance. The silencing groove is a gradual notch shape volume, contact surface area, and volume slowly increasing toward the manifold. The present study finds out the pump"s efficiencies based on output fluid power and inputs mechanical energy for with and without silencing groove model. The simulation results manifest the silencing groove valve plate model is more efficient than the without silencing groove valve plate model of the pump.
