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.
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.
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.
