- | ====== Summary of the problem ====== | + | Disregard |
- | + | ||
- | I have limited experience with pneumatics, so it would be pretty nice if someone could read this and provide some criticism. If the opinion is positive, I will build this system, and publish the results, performance and issues | + | |
- | + | ||
- | I was researching the possibility of most cost-effective, | + | |
- | + | ||
- | -pneumatic tool operation (better than electric - lighter, more powerful, less moving elements) | + | |
- | + | ||
- | -sanding (most universal abrasive processing method) | + | |
- | + | ||
- | -vacuum generation (electronics, | + | |
- | + | ||
- | -injection (moulding, oiling) | + | |
- | + | ||
- | -spray-coating | + | |
- | + | ||
- | -hi-quality spray painting | + | |
- | + | ||
- | -refrigeration through vortex tube | + | |
- | + | ||
- | I want this to be as simple as possible, with fewest elements, and ability to power the setup through different means (in case there is no electricity available) | + | |
- | + | ||
- | Generation of huge volumes of air require a lot of power, and use of screw compressors. They are good for continuous work, and the variable rotation speed compressors are prohibitively costly. Additionally, | + | |
- | + | ||
- | I decided to go a different path - contain huge volumes of highly compressed air, generated by underloaded hi-pressure compressor. | + | |
- | + | ||
- | ====== The solution ====== | + | |
- | + | ||
- | The solution fits within 16000 PLN net sum total. | + | |
- | + | ||
- | Compressor: Atlas Copco LT 3-30 or 4-30 (10000-12000 PLN, 2000 PLN net price difference, higher model has doubled FAD (Free Air Delivery - the amount of air the compressor can generate))(brochure: | + | |
- | Why: It's an industrial compressor, fit for continuous work. It should last forever in our application, | + | |
- | + | ||
- | Tank: http:// | + | |
- | Why: The tank is relatively small (compared to the volume of air it can house), and is relatively mobile - two people (or a single stron person) can load it onto a vehicle in a horizontal position by simply tipping it. It is not the best money/ | + | |
- | + | ||
- | Benefits: | + | |
- | -Dry air. The pressure in the installation is suited for power tools and other general tasks, therefore it's lower than the pressure in the tank. Because the pressure is reduced, the water is not gathering in the pneumatic plumbing/ | + | |
- | -No air pulsation | + | |
- | -If inlet of air is at the bottom of the tank, the water present in the tank will act as a filter. | + | |
- | -Heavier particles (oil) will have time to settle down into the water during the time the tank is unused. | + | |
- | + | ||
- | Additional elements: Tank exit air warming. | + | |
- | The working air that exits onto your tools is heated up with heat from compression, | + | |
- | + | ||
- | The aim of this setup should allow for a very good performance in short tasks, and relatively cheap expandability if prolonged use is required (buying additional tanks). | + | |
- | + | ||
- | Additionally, | + | |
- | + | ||
- | Opinions please. | + |
