Abstract

A 3D-printed oil separation assembly for use in a reciprocating compressor is provided. The compressor includes a suction chamber, a crankcase chamber, and at least one partition member at least partially separating the suction chamber and the crankcase chamber. The at least one partition member further includes at least one opening. The 3D-printed oil separation assembly comprises a coalescing structure positioned within the crankcase chamber adjacent the at least one partition member at the at least one opening; and at least one securing structure secured in operable relation with the at least one demisting structure so as to secure the coalescing structure relative to the opening. The coalescing structure comprises at least one structure selected from the group consisting of a baffled structure, a demisting structure, and combinations thereof. At least a portion of the coalescing structure is 3D-printed.

Claims (16)

1. A method of making a coalescing structure for use in a reciprocating compressor, the method comprising:

designing a coalescing structure configuration;

programming a 3D printer based on the coalescing structure configuration; and

3D printing at least a portion of the coalescing structure;

wherein the coalescing structure comprises a baffled structure, and 3D printing at least a portion of the coalescing structure comprises 3D printing at least a portion of the baffled structure.

2. The method of claim 1 , wherein the step of 3D printing at least a portion of the coalescing structure comprises 3D printing the entirety of the coalescing structure.

3. The method of claim 1 , wherein 3D printing at least a portion of the coalescing structure comprises 3D printing the entirety of the baffled structure.

4. The method of claim 1 , wherein the at least one baffled structure comprises an outer wall and a plurality of sloped baffles.

5. The method of claim 1 , wherein the coalescing structure further comprises a demisting structure, and 3D printing at least a portion of the coalescing structure comprises printing at least a portion of the demisting structure.

6. The method of claim 5 , wherein 3D printing at least a portion of the coalescing structure comprises 3D printing the entirety of the demisting structure.

7. A method of making a coalescing structure for use in a reciprocating compressor, the method comprising:

designing a coalescing structure configuration;

programming a 3D printer based on the coalescing structure configuration; and

3D printing at least a portion of the coalescing structure;

wherein the coalescing structure comprises a baffled structure and a demisting structure, and 3D printing at least a portion of the coalescing structure comprises 3D printing at least a portion of the baffled structure and at least a portion of the demisting structure.

8. The method of claim 7 , wherein 3D printing at least a portion of the coalescing structure comprises 3D printing the entirety of the baffled structure and the demisting structure.
