Attach your hand pump or bicycle pump to the top of the bottle using another piece of tubing. Make sure it is securely fitted and sealed. This is the component that will help evacuate air from the bottle.
Step 6: Seal and Test Your Vacuum Pump
Once all components are in place and sealed, your vacuum pump is ready for a test run. Before you begin, ensure everything is airtight by checking for air leaks. You can do this by running your hand around any seals; if you feel air escaping, reapply the sealant.
Operating Your Vacuum Pump
To operate your newly constructed vacuum pump, follow these straightforward steps:
Step 1: Start Pumping
Begin by slowly pumping the mechanism. As you pull the handle of the pump, air will be drawn out of the bottle, creating a vacuum inside.
Step 2: Monitor the Gauge
Keep an eye on the vacuum gauge as you pump. The gauge should indicate a decrease in pressure, meaning a vacuum is being created.
Step 3: Stopping the Pump
Once you reach the desired vacuum level, you can stop pumping. The one-way valve will ensure that the air won’t flow back in, maintaining the vacuum state.
