Abstract
An accumulator assembly for a pump system at a well site is arranged to fluidically connect to a flow line between a blender and a fracturing pump of the pump system. The accumulator assembly includes a pressurizable tank configured to contain pressurized fluid; and, a control valve fluidically connected between a discharge end of the tank and the flow line. The control valve opens and fluidically connects the tank to the flow line when a pressure on the flow line is less than a target pressure, and the control valve closes and fluidically blocks communication between the tank and the flow line when the pressure on the flow line is greater than or substantially same as the target pressure.
