Device used to control damaging hydraulic pulsations in manifolded multi pump systems used in hydraulic fracturing

Abstract

To reduce pulsation amplitudes to the pumps and from pumps to the downstream components, as well as to provide greater flexibility in integration of pulsation control dampeners with other elements of an overall pump system, when a plurality of pumps operate together using a common manifold, the hydraulic interaction of the pumps is given special consideration beyond the pulsation control techniques and equipment that may be used for a single pump. To improve the life expectancy of the manifold and affiliated items used in a multi pump system, an acoustic/pulsation control device inhibits or mitigates damaging transient pulsations. The acoustic/pulsation control device is installed to control the pulsations and thus reduce damaging vibrations.
