Hydro Do That?

This pump was made for a Glasgow School of Art Project, "Hydro Do That?". We were divided into groups of 4 and have to design and make a device that can lift 5 litres of water up 60 cm within 5 minutes. The device with the highest efficiency wins.

We were only given a 24V DC motor with 3500RPM to start with.

Groups were named after sea creatures and our group was the "Clown Fish".

After researching, we think that a Rope Pump will be the most efficient water lifting device we can make in the workshop.

Step 1: The Gear Box Platform


A gear box is required to increase to torque of the 24V DC 3500 RPM moter from 0.1nm to 2.5nm. We built a platform for the motor and the gear box.

The gear box consist two 45 teeth driven gear and two 9 teeth pinion gear.

The platform is a 240mm x 320mm x 15mm MDF board. Two triangle support poles were also used.

Motor Stand:

The motor stand is made of two95mm x 115mm x 18mm MDF board. Cut them by following the instructions on the pictures. The motor given has a diameter of 36mm, change the hole to the required diameter if the motor used is different.

Two set screws for each board will be drilled in. They are very awkward to work with in this case, since it is MDF, drilling from the edges can rip the MDF open very easily, we used MDF only because it matches the platform.

<p>What did you use for 3d modelling and rendering?</p>
<p>The software used was Solidworks, for rendering is photoview 360 which comes with Solidworks. :D</p>
<p>Graphic and text presentations are excellent.</p>
<p>Great work, but maybe is more efficient to adapting in your project an Peristaltic pump </p><p>https://www.instructables.com/id/Inexpensive-easy-to-build-peristaltic-pump/?ALLSTEPS</p>
<p>What makes you say that? Peristaltic pumps are not particularly efficient, when htey are doing a decent amount of work squishing tubing.</p>
<p>If you replace rope with plastic tubeing you will find it will strip oil off water.</p><p>It will only pump the oil!</p>
<p>A great Instructable, it is good to see young engineers in the making, there is always a place on the job market for good engineers.</p><p>regards Poppy Ann.</p>
<p>Nice work! I think efficiency could be further improved if the pipe diameter above the tee-piece was wider. You'd suffer less water loss out the top of the pump, as the seal between the washers on the rope and the side wall of the pipe would be broken after the washer passed the tee. Well done on winning and breaking the previous record!</p>
<p>congrats for winning! which is the power of the motor (watts)?</p><p>does the rope have some pistons on it? maybe you can show it in the renders..</p>
<p>Thank you! I am not entirely sure though I think the Current we ran on was 0.4A, and 24V, so 9.6W. I apologize that the page was not finished, I have updated it already and the rope have pistons on them. I would love to show the rope and pistons in renders, however I am still trying to figure out how to make a rope and attach thing on to it in Solidworks, and thank you for your comment :D</p>
