Step 3: Create the Piston Mechanism
The piston is what will create the vacuum when operated. If you’re crafting your piston, follow these guidelines:
Design Your Piston: Take a flat piece of material (wood or metal) and shape it into a cylinder that can fit snugly inside the container.
Attach a Handle: Fix a handle to the top of the piston to give you leverage as you pump. Ensure it is firmly attached and can withstand repeated use.
Lubricate the Piston: Apply a thin layer of lubricant around the edge of the piston to ease the operation. This will help the piston move smoothly and create a better seal.
Step 4: Assemble the Pump
Now it’s time to put everything together to complete your manual vacuum pump.
Insert the Piston: Place the crafted piston inside the container, ensuring it can move up and down freely without obstructing the tubing.
Put on the Lid: Secure the lid tightly onto your container, ensuring the rubber tubing and check valve are still in place.
Final Checks: Before using your pump, double-check all connections, seals, and fitments to prevent any leaks.
Step 5: Testing Your Vacuum Pump
Now that your manual vacuum pump is assembled, it’s time to put it to the test.
Prepare for Use: Place the items you want to vacuum seal inside the container (if applicable) and ensure the lid is secured tightly.
Pump the Piston: Begin to pump the handle of your piston. You should feel resistance as the pressure decreases within the container.
Check for Leaks: If your pump is functioning correctly, check for any air leaks by feeling around the edges of the lid and tubing connections. If you feel air escaping, reapply sealant as needed.
