Materials Needed for a DIY Vacuum Pump
Have you ever needed a vacuum pump, but were discouraged by the high prices of commercial ones? A DIY vacuum pump can be made at home with inexpensive materials, and it can be used for a variety of purposes, such as testing electronic components, degassing liquids, or even extracting essential oils from plants. Here are the materials you will need to make a simple and effective vacuum pump:
1. Airtight container
The first component of a DIY vacuum pump is an airtight container that can withstand negative pressure. This can be any container that has a tight-fitting lid and is made of durable material, such as glass, plastic, metal or rubber. However, plastic containers are not recommended for prolonged vacuum use, as they may deform or crack under pressure. The container should also be large enough to hold the objects or liquids that you want to vacuum. If you are unsure about the airtightness of your container, you can test it by sealing it and putting it under water: if no bubbles escape, then it’s airtight.
2. Vacuum gauge
A vacuum gauge is a device that measures the amount of negative pressure or vacuum in your system. It is essential for controlling the level of pressure and avoiding overpressure, which could damage your container or impede the vacuum process. A vacuum gauge can be a simple analog gauge with a range of -30 inHg to 0 inHg, or a digital gauge that displays the pressure in bars, kPa, or mmHg. The gauge should be mounted on the lid of your container, along with a valve or a stopcock that can regulate the pressure and allow air to re-enter the container when needed.
If you cannot afford a vacuum gauge, you can use a cheap and easy alternative: a water manometer. A water manometer is a U-shaped tube filled with water, and it works by balancing the pressure of the vacuum against the weight of the water column. You can make a water manometer by connecting a transparent tube to a hose barb that fits the lid of your container, and submerging the tube in a container of water. The vacuum level can be read by the height of the water column, which should ideally be around 25-30 mm for a full vacuum.
3. Vacuum pump
The heart of a vacuum pump is, of course, the pump itself. A vacuum pump is a device that reduces the air pressure inside your container, by pumping out the air molecules and creating a partial vacuum. There are two types of DIY vacuum pumps: mechanical pumps and venturi pumps.
A mechanical pump is a motor-driven pump that pumps out the air directly, and is the most powerful and efficient type of pump, but also the most complex and expensive to build. It requires a motor, a piston or diaphragm, check valves, inlet and outlet ports, and sometimes a lubrication system. Mechanical pumps can achieve a vacuum level of up to 1 micron (0.001 mmHg) and are suitable for heavy-duty applications, such as vacuum forming, vacuum casting, or freeze-drying.
A venturi pump, on the other hand, is a simple and low-cost pump that uses the Venturi effect to create suction. The Venturi effect is a phenomenon that occurs when a fluid (such as air or water) flows through a narrow tube or nozzle, and its velocity increases while its pressure decreases. By connecting a nozzle or a venturi tube to your container, and a high-pressure air source (such as a compressor or a bicycle pump) to the nozzle, you can create a vacuum by sucking out the air through the nozzle. Venturi pumps are less powerful and can achieve a vacuum level of up to 200-300 mmHg, but they are easy to make and maintain, and can work with a variety of air sources.
4. Tubing and fittings
In order to connect the vacuum pump to your container and the vacuum gauge, you will need some tubing and fittings. The tubing should be made of flexible, transparent, and airtight material, such as PVC, silicone, or rubber. The diameter of the tubing depends on the flow rate and vacuum level of your pump, but it should be at least 1/4 inch (6 mm) for venturi pumps, and 3/8 inch (9.5 mm) for mechanical pumps. The fittings should be made of compatible materials and should have tight seals, such as hose barbs, quick-connect couplings, or compression fittings.
You will also need some additional tools and accessories, such as pliers, scissors, a drill, a gasket material, a sealing compound, and a vacuum trap or filter to prevent contaminants from entering your pump or your container.
Building a DIY vacuum pump requires some effort and skill, but it can be a rewarding and educational experience. By understanding the principles and components of vacuum technology, you can expand your knowledge and creativity, and even save money and resources. Happy vacuuming!
