Abstract
To inhibit damage to or failure of the bladder within a bladder-type pulsation dampener, an internal passage of a bladder saver device carrying pumped fluid from the pulsation bleed plate mounted within the internal passage and movable between a first position in which the pulsated fluid flow is unencumbered by the bleed plate and a second position in which the pulsated fluid flow is restricted by the bleed plate.
Claims20
A device for use with a bladder-type pulsation dampener, the device comprising:
- a housing that includes an internal passage for a pulsated fluid flow, wherein the housing is formed of an upper body ring with an internal annulus, a middle body ring, and a lower body ring;
- a bleed plate mounted within the internal passage and movable, in response to increasing fluid pressure of fluid flowing through the internal passage, between a first position in which the pulsated fluid flow through a fluid outlet for the internal passage is least encumbered by the bleed plate and a second position in which the pulsated fluid flow through the fluid outlet is restricted by the bleed plate, wherein the bleed plate includes a plurality of holes to allow equalization of pressure through the internal passage when a fluid pressure of the pulsated fluid flow causes the bleed plate to move into the second position;
- a central shaft coupled to the housing and extending through the internal passage, wherein the bleed plate floats around the central shaft between the first position and the second position;
- and
- a throat plate coupled to the central shaft, wherein the throat plate is fixed within the housing in a space defined by the internal annulus and an outer surface of the middle body ring.

A system, comprising:
- a strainer cross coupled to a pump discharge to filter large particles;
- a bladder saver device coupled to the strainer cross to be in fluid communication with a cross fluid passage of the strainer cross, the bladder saver device includes:
- a housing that includes an internal passage for a pulsated fluid flow, wherein the housing is formed of an upper body ring with an internal annulus, a middle body ring, and a lower body ring,
- a bleed plate mounted within the internal passage and movable, in response to increasing fluid pressure of fluid flowing through the internal passage, between a first position in which the pulsated fluid flow through a fluid outlet for the internal passage is least encumbered by the bleed plate and a second position in which the pulsated fluid flow through the fluid outlet is restricted by the bleed plate,
- a central shaft coupled to the housing and extending through the internal passage, wherein the bleed plate floats around the central shaft between the first position and the second position, and
- a throat plate coupled to the central shaft, wherein the throat plate is fixed within the housing in a space defined by the internal annulus and an outer surface of the middle body ring;
- and
- a pulsation dampener coupled to the bladder saver device to be in fluid communication with the internal passage,
- wherein the bleed plate includes a plurality of holes to allow equalization of pressure through the internal passage when a fluid pressure of the pulsated fluid flow causes the bleed plate to move into the second position.

An integrated bladder saver device for use with a bladder-type pulsation dampener, the integrated bladder saver device comprising:
- a strainer cross portion coupled to a pump discharge to filter large particles;
- a bladder saver portion extending from the strainer cross portion to be in fluid flow with a cross fluid passage of the strainer cross portion, the bladder saver portion includes:
- a housing that includes an internal passage for a pulsated fluid flow, wherein the housing is formed of an upper body ring with an internal annulus, a middle body ring, and a lower body ring,
- a bleed plate mounted within the internal passage and movable, in response to increasing fluid pressure of fluid flowing through the internal passage, between a first position in which the pulsated fluid flow through a fluid outlet for the internal passage is least encumbered by the bleed plate and a second position in which the pulsated fluid flow through the fluid outlet is restricted by the bleed plate, wherein the bleed plate includes a plurality of holes to allow equalization of pressure through the internal passage when a fluid pressure of the pulsated fluid flow causes the bleed plate to move into the second position,
- a central shaft coupled to the housing and extending through the internal passage, wherein the bleed plate floats around the central shaft between the first position and the second position, and
- a throat plate coupled to the central shaft, wherein the throat plate is fixed within the housing in a space defined by the internal annulus and an outer surface of the middle body ring.
