Beginning of The Project¶
The Project¶
The project is a pump using Positive Displacement method known as peristaltic pump. And make it more accurate.¶
How Does Peristaltic Pump Work?¶
A Peristaltic Pump works by either two shoes (high-pressure applications) or rollers (low-pressure applications) rotating on a wheel inside of the pump and compressing an internal hose, which then forces through a known quantity of fluid, hence the name of the product. The hose inside of a Peristaltic Pump is designed to return to its original shape after the shoes or rollers have passed over, so the quantity and flow of fluid are consistently maintained.[1]

Mothed For Calibrate and Accurate of The Pump¶
We searched in google and find calibrate and accurate of the pump need to run the pump for specific time and full it in measure cup and calculate the flow rate. Then by program we can make it more accurate to stop in specific amount of fluid.
Initial Idea Design Options for The Project¶
we choose the pump Design base on the equipment on Fab Lab and we focus on using 3D printer.
First Option¶
The first option design idea we take it from ScienceDirect[2], because the cost of the equipment require is low and most of the equipment are in Fab Lab.
[2]
Second Option¶
For second option we choose it because most of the pump will be 3D print and we take it from UltiMaker Thingiverse [3]
3D Print¶
We learned how to use 3D printer and print the designs of the pump.
How to Use 3D Printer?¶
- You need to connected filament
- Then check the radius pipe
- But the SD card
- Then choose Print
- Next choose the file you want to print
- Then press on Continue
- After you choose the file the printer will pump filament intel the pump clear the air inside the pipe
- Now the printer is printing the Designs
First Attempt to print the Designs¶
The printer is failed to print the designs, because the base was dirty. And you can see the printer print a little and stop.
The Base Circuit for First Option Design¶
We connected the Circuit to confer that the existing equipment are enough and not broken and can run the motor.
The code to run motor in one direction using Nano Arduino and L298N H-Bridge.¶
#define MotorIN1 4 // input1 is connected to d4
#define MotorIN2 5 // input2 is connected to d5
void setup() {
// MotorIN1 and MotorIN2 are Initialized as Output <p>
pinMode(MotorIN1, OUTPUT);
pinMode(MotorIN2, OUTPUT);
}
void loop() {
// rotating in one direction
digitalWrite(MotorIN1, HIGH);
digitalWrite(MotorIN2, LOW);
delay(1000);
}
