Abstract:
Different inner diameter internal or external pressure drop tubes or orifice plate openings producing different discharge pressure pulse amplitudes are employed in a pump pulsation control reactive discharge dampener. Either both pressure drop tubes/orifice plates may be mounted concurrently on or in the dampener, connected to different discharge pipes used selectively by the operator depending upon the piston or plunger size being employed, or the pressure drop tubes/orifice plates may be interchangeable.
Abstract:
Performance parameters for a reciprocating pump including pulsation energy, temperature energy, solids, Miller number and chemical energy and the like are monitored and employed to at least periodically compute a total energy number over the operating life of the pump. The current computed value is compared to a predictive failure value empirically determined for the respective pump design, to determine when failure is likely to be imminent. Scheduling of maintenance with other pumping operations and objective rating of competing designs is possible based on the total energy number.

Abstract:
A pulsation control device coupling a reciprocating pump with either suction or discharge piping and having a generally spherical or cylindrical interior chamber includes a curved baffle with a pressure drop device (e.g., a choke) separating the interior chamber into two volumes and forcing fluid flow through the pressure drop device. The effective fluid passage provided by the pressure drop device 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 in response to operation of the reciprocating pump. The pressure drop device dampens high frequency pulsation magnitudes of pressure pulses within fluid passing through the interior chamber in response to operation of the reciprocating pump.

A pulsation control device coupling a reciprocating pump with either suction or discharge piping and having a generally spherical or cylindrical interior chamber includes a curved baffle with a pressure drop device (e.g., a choke) there through separating the interior chamber into two volumes and forcing fluid flow through the pressure drop device. The effective fluid passage provided by the pressure drop device 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 in response to operation of the reciprocating pump, and in particular improves acoustic pulsation energy reduction. The pressure drop device dampens high frequency pulsation magnitudes of pressure pulses within fluid passing through the interior chamber in response to operation of the reciprocating pump.
