Abstract

A manifold through which a fluid is adapted to flow. The manifold includes an elongated member at least partially defining a fluid chamber through which the fluid is adapted to flow, a longitudinal axis, and an interior surface; a fluid liner disposed within the fluid chamber and adapted to dynamically respond to pressure fluctuations within the fluid chamber as the fluid flows therethrough; and a wear indicator positioned radially between the interior surface of the elongated member and the longitudinal axis. The fluid liner is subject to wear and/or erosion due to the flow of the fluid therethrough and/or the dynamic response of the fluid liner to the pressure fluctuations within the fluid chamber. The wear indicator is adapted to indicate the degree to which the fluid liner has been subjected to the wear and/or erosion.

First claim

What is claimed is:

1. A manifold through which a fluid is adapted to flow, the manifold comprising:
an elongated member at least partially defining a fluid chamber through which the fluid is adapted to flow, a longitudinal axis, and an interior surface, the elongated member comprising: one or more inlets via which the fluid flows into the fluid chamber; and one or more outlets via which the fluid flows out of the fluid chamber;
a fluid liner disposed within the fluid chamber and adapted to dynamically respond to pressure fluctuations within the fluid chamber as the fluid flows therethrough, the fluid liner being subject to at least one of wear and erosion due to the flow of the fluid therethrough and the dynamic response of the fluid liner to the pressure fluctuations; and
a wear indicator positioned radially between the interior surface of the elongated member and the longitudinal axis, the wear indicator comprising a wear groove formed in the fluid liner and devoid of any component of the manifold;
wherein the wear indicator is adapted to indicate the degree to which the fluid liner has been subjected to the at least one of wear and erosion.

2. The manifold of claim 1 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the wear body comprising a plurality of separate body segments that are graduated, or stepped, with respect to one another, wherein at least one of the wear segments is spaced from the longitudinal axis at a different distance than at least another one of the wear segments, at least respective portions of the body segments being embedded in the fluid liner.

3. The manifold of claim 1 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the wear body forming a non-annular three-dimensional shape.

4. The manifold of claim 1 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the wear body being in contact with the interior surface of the elongated member.

5. The manifold of claim 1 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, at least a portion of the fluid liner extending between the wear body and the interior surface of the elongated member so that the wear body does not contact the interior surface of the elongated member.

6. The manifold of claim 1 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the fluid liner covering the wear body so that at least a portion of the fluid liner extends between the wear body and the longitudinal axis of the elongated member, thereby initially preventing the fluid that flows through the fluid chamber from contacting the wear body.

7. The manifold of claim 1 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the wear body being formed of a first material and the fluid liner being formed of a second material that is different from the first material.

8. The manifold of claim 1 , wherein the wear groove comprises a plurality of separate groove segments that are graduated, or stepped, with respect to one another, wherein at least one of the groove segments is spaced from the longitudinal axis at a different distance than at least another one of the groove segments.

9. The manifold of claim 1 , wherein the wear groove defines a non-annular three-dimensional shape.

10. The manifold of claim 1 , wherein the wear groove is formed in the interior of the fluid liner.

11. The manifold of claim 1 , wherein the wear indicator further comprises a wear body embedded in the fluid liner and having an erosion rate less than that of the fluid liner, wherein, as the fluid liner at least one of wears and erodes, the wear body protrudes from the fluid liner to an increasing degree.

12. A fluid end portion for a reciprocating pump assembly, the fluid end portion comprising:
a fluid end block, comprising:
a pressure chamber;
a plunger adapted to reciprocate within the pressure chamber; and
a discharge manifold in fluid communication with the pressure chamber;

and
a suction manifold through which a fluid is adapted to flow, the suction manifold being connected to the fluid end block and comprising:
an elongated member at least partially defining a fluid chamber through which the fluid is adapted to flow, a longitudinal axis, and an interior surface, the elongated member comprising: an inlet via which the fluid flows into the fluid chamber; and an outlet via which the fluid flows out of the fluid chamber, the outlet being in fluid communication with the pressure chamber;
a fluid liner disposed within the fluid chamber and adapted to dynamically respond to pressure fluctuations within the fluid chamber as the fluid flows therethrough, the fluid liner being subject to at least one of wear and erosion due to the flow of the fluid therethrough and the dynamic response of the fluid liner to the pressure fluctuations; and
a wear indicator positioned radially between the interior surface of the elongated member and the longitudinal axis, the wear indicator comprising a wear groove formed in the fluid liner and devoid of any component of the manifold;

wherein the wear indicator is adapted to indicate the degree to which the fluid liner has been subjected to the at least one of wear and erosion.

13. The fluid end portion of claim 12 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the wear body comprising a plurality of separate body segments that are graduated, or stepped, with respect to one another, wherein at least one of the wear segments is spaced from the longitudinal axis at a different distance than at least another one of the wear segments, at least respective portions of the body segments of the wear body being embedded in the fluid liner.

14. The fluid end portion of claim 12 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the wear body forming a non-annular three-dimensional shape.

15. The fluid end portion of claim 12 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the wear body being in contact with the interior surface of the elongated member.

16. The fluid end portion of claim 12 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, at least a portion of the fluid liner extending between the wear body and the interior surface of the elongated member so that the wear body does not contact the interior surface of the elongated member.

17. The fluid end portion of claim 12 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the fluid liner covering the wear body so that at least a portion of the fluid liner extends between the wear body and the longitudinal axis of the elongated member, thereby preventing the fluid that flows through the fluid chamber from contacting the wear body.

18. The fluid end portion of claim 12 , wherein the wear indicator further comprises a wear body embedded in the fluid liner, the wear body being formed of a first material and the fluid liner being formed of a second material that is different from the first material.

19. The fluid end portion of claim 12 , wherein the wear groove comprises a plurality of separate groove segments that are graduated, or stepped, with respect to one another, wherein at least one of the groove segments is spaced from the longitudinal axis at a different distance than at least another one of the groove segments.
