Water Pump
Overview:
For this project, a team of 5 others and I were tasked to design, machine, test and analyze an efficient water pump (given tight budget constraints), capable of producing at least 1L of water in 1 minute. Our design is a 4-cylinder, scotch-yoke driven piston pump, capable of delivering 4.8L of output on our 60-second test-run. This project was part of a design course at Cornell University (MAE 2250: Mechanical Synthesis).
Design Process
-
Brainstorm water pump design and compare with group of 5 to select one.
My proposal: peristaltic pump

2. Group selection: Four-Stroke Piston Pump
We decided on a scotch-yoke mechanism as the main component of our design because of its stability and lack of joints; not only was the design intricate, but efficient as well. We initially decided on a 2-cylinder scotch yoke design, but we decided to challenge ourselves further by then committing to a 4-cylinder design.
Final Sketch
3. Manufacturing & Assembly
We began by analyzing the Emerson shop parts list, specifically, our intended budget, and accordingly creating our full CAD model; we then split up the manufacturing responsibilities among the group and began machining (guided by our individual parts drawing from Fusion).

4. Testing
Motor and test setup was provided.
Assembly prior to testing
Results:
4.8L of water in 60 seconds --> surpassing design goal of 1L/min.
