Development of a Pressure Pulsation Damper for Gas Pressure Regulators with Account of Operation Parameters

Abstract

A design concept of a gas flow pulsation damper at a pressure regulator outlet is offered. It is formulated the operational principle of this damper, which contains the orifice with high and low resistance and also the stabilizer (vortex damper) of an outflow. Future references for choosing the diameter and the amount of passages in the orifices are also done. It is proposed the sequence of choosing the damper parameters, which contains the stages of tentative gas-dynamic calculation of the plain washer parameters on basis of the Saint-Venant-Wenzel formula and the final modeling, produced on basis of the numerical simulation. It is presented the pulsation damper, which was developed by the offered method.

Flow pulsation reduction of a single-piston piezoelectric pump based on elastic cavity group and unloading valve

“…The research on eliminating the pressure and flow pulsation of the pump has attracted wide attention. [10][11][12][13][14][15] A new vibration active control method was presented to diminish the vibrations of the fluid power supply efficiently. 16 O'Shea 17 discussed the theory and implementation to reduce flow pressure ripple by influencing the speed of a relatively-high volumetric displacement lowinertia pump through open-loop control of the driving motor torque.…”
