The progress that I have done up until now is that I’ve tested out all three conditions of the Electromechanical Valve. The three conditions are:
1. Normal Condition
2. Leakage Condition
3. Overheat Condition
Normal Condition
For normal condition, the EMV is connected as in the picture below. A total of 8 hours was needed to record the current and temperature. Every 15 minutes, the current and temperature measurements are recorded. The current of the EMV will be measured with a multimeter linked in series, while the temperature will be measured by directing the digital thermometer to the maximum temperature on the EMV's surface. Ohm's Law will be used to compute the EMV's resistance. The data will be saved in Google Sheets for analysis, and a graph of the data will be made using the Google Sheets capabilities.
Leakage Condition
The procedures for the leakage situation are nearly identical to those for the controlled state. The EMV, on the other hand, will be immersed within a water-filled enclosure. The main reason for this is that water would ultimately enter and overflow within the EMV, causing issues such as body leakage, lower magnetic efficiency, and inappropriate media flow. EMV will be lifted out of the water and measured quickly to determine current and temperature. The picture to test the leakage condition is potrayed below.
Overheating Condition
The plan of action for an overheated state is similar to that for a controlled or leaking condition. The difference is that the EMV will be placed within a temperature control chamber and heated to its maximum temperature. The goal is to overheat the EMV by imagining it being abruptly supplied by overflowing supply voltage electricity. The current and temperature of the EMV will be monitored during the 8-hour overheating period. The image of testing the EMV in overheat condition is illustrated below.
Besides that, I also started on continuing my Chapter 4 for my thesis where I will be showing the methodology and results of my project.
