How to Make a Vacuum Pump

Creating a vacuum pump is an easy and rewarding project for any tinkerer or science enthusiast. With a few tools and materials, you can assemble a vacuum pump that can be used in a variety of applications.

Steps:

1. Gather the materials and tools you’ll need to construct the vacuum pump. These include: a large glass jar, a smaller jar, rubber tubing, plastic tubing, a few metal clamps, two vacuum nipples, a check valve, a strong adhesive, and a few pieces of welding rod to stabilize the construction.
2. Drill a small hole in the side or the top of the larger glass jar to insert the two vacuum nipples. Insert them slightly apart, about 1-2 cm apart. Attach the metal clamps.
3. Connect the rubber tubing to the vacuum nipples and connect the other end to the check valve. The check valve should be oriented to flow air in the same direction as the arrows on the valve.
4. Attach the plastic tubing to the other end of the check valve. Connect the other end to the smaller jar. Use the adhesive to firmly connect all the parts.
5. Fill the larger jar with distilled water, leaving a few centimeters of air space between the top of the jar and the level of the water.
6. Bend the welding rods and insert them into both sides of the larger jar. This stabilizes the structure and prevents it from wobbling.
7. Turn the valve or switch located on the check valve to activate the vacuum pump. This closes the valve, allowing air to be sucked through the vacuum nipples from the larger jar into the smaller jar, creating a vacuum.

Your vacuum pump is now complete and ready to be used. Enjoy experimenting with the projects you create with your new vacuum pump!

How to Make a Vacuum Pump

Building a vacuum pump can be a fun way to learn about air pressure and to create a useful tool that can help you in many different activities. With a few simple materials and some patience, you can create a vacuum pump that will help you in a variety of projects. Follow these steps to make your own vacuum pump.

Things You'll Need:

• One 2-liter soda bottle
• One roll of duct tape
• Strong scissors or a box cutter
• One section of bicycle inner tube
• One 12-inch plastic tube
• One brass valve featuring a 1/4 inch NPT connection
• One medium sized PVC pipe and Glue

Creating the Pump:

1. Using the scissors or box cutter, cut the neck off the soda bottle.
2. Cut a 3-inch-long section of bicycle inner tube and then use the duct tape to attach it on the soda bottle.
3. Use the scissors or box cutter to cut the plastic tube into 2 sections around 6-inches in size.
4. Connect the 1/4-inch NPT brass valve on the plastic tube section that was not cut.
5. On one side of the couple, attach a medium-size PVC Pipe with some glue and a clamp.
6. Attach the other side of the couple to the neck of the soda bottle.
7. Attach the other section of the PVC pipe to the outlet side of the brass valve.
8. Tape the whole system together with the duct tape ensuring the connections are secure.
9. Your homemade vacuum pump is now finished and ready to use.

Tips:

• Make sure all the connections are securely taped.
• The valve should be securely in place and no air should be escaping.
• Maintain the vacuum pump carefully and it should last you for a long time.
