Reduced Flow Fluctuation of Radial Piston Pump with Silencing Groove Valve Plate
Lokesh Kumar,Nimai Pada Mandal 한국유체기계학회 2022 International journal of fluid machinery and syste Vol.15 No.1
The theoretical study and numerical analysis have been carried out on the valve plate geometry of the radial piston pump to reduce the flow and pressure fluctuation. The radial piston pump is widely used in industrial applications as a hydraulic power source. The pressure and flow fluctuation of pump produce an adverse effect for the hydraulic system. The geometries of valve plate are studies for the analyses of pressure and flow fluctuation of the pump. The explicit area calculation of the piston kidney over the manifold is carried out to simulate the main flow in between piston chamber and manifold in vale plate configurations of with silencing groove, without silencing groove and with silencing groove cum damping orifice. The analyses of cross-port leakage is done at transition zone near at top dead centre (TDC) and bottom dead centre (BDC) of the valve plate, study the effects of cross-port leakage on pressure and flow fluctuation with volumetric efficiency of the pump. Studies the pump pressure and flow build up characteristic under varying load and validated with existing pump performance. The simulation results suggest that the silencing groove valve plate model is better perform than other configurations in terms of high flow rate, low pressure and flow fluctuation with less cross port leakage and more volumetric efficiency.

Effect of Silencing Groove in Valve Plate on Efficiency of Radial Piston Pump
Lokesh Kumar,Nimai Pada Mandal 한국유체기계학회 2023 International journal of fluid machinery and syste Vol.16 No.2
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.
