Have any of you used pulse dampeners? What is the working principle of pulse dampers, and what parameters are needed for their selection?
This issue involves such a wide range of aspects,,,,. I’m not sure which field it belongs to; for example, volume shock absorbers can also be called pulse dampers, right? P is just talking nonsense: lol
To select an appropriate pulsation damper, it is first necessary to determine the required pulsation reduction rate based on the actual conditions at the site and the process requirements, and then to choose the suitable model using this technical criterion. The accurate selection of a pulsation damper should be determined through comprehensive calculation and analysis based on parameters such as flow rate, pressure, pump type, pump speed, number of pump cylinders, pump phase difference (for multi-stage pumps), pulsation reduction rate, application purpose, composition of the fluid in the pipeline, density of the fluid in the pipeline, viscosity of the fluid in the pipeline, and temperature of the fluid in the pipeline. Based on the above parameters, it is essential to calculate the pulse volume of the fluid (i.e., the volume of liquid delivered per pulse) and the pulsation frequency. By combining this with the pulsation elimination rate indicator, it is possible to preliminarily determine the type and volume of pulsation dampers required. For example, if it is required that the residual pulsation be kept within 10%, the pulse volume be 1 liter per cycle, and the pulsation frequency be 2 cycles per second, then diaphragm-type or airbag-type pulsation dampers can be used, with a capacity of at least 10 liters.
A pulsation damper is a pressure vessel used to eliminate pressure or flow fluctuations in liquids within pipes. It helps to stabilize fluid pressure and flow, reduce pipe vibrations, protect downstream instruments and equipment, and improve the volumetric efficiency of pumps.
