PUMP PULSATION DISCHARGE DAMPENER WITH CURVED INTERNAL BAFFLE AND PRESSURE DROP FEATURE CREATING TWO INTERNAL VOLUMES

摘要

A pulsation control device, coupled to a reciprocating pump with either suction or discharge piping, and having a spherical or cylindrical interior chamber that includes a curved baffle with a pressure drop device, e.g. a choke, separating the interior chamber into two volumes, is disclosed. The pulsation control device forces fluid flow through the pressure drop device, which provides an effective fluid passage that is smaller than the fluid passage for one or both of the inlet to and/or the outlet from the interior chamber. Fluid entering the pulsation control device reacts with fluid contained within the volume thereof on both sides of the baffle. The baffle attenuates pressure pulses within fluid passing through the interior chamber and improves acoustic pulsation energy reduction. The pressure drop device dampens high frequency pulsation magnitudes of pressure pulses within fluid passing through the interior chamber.
