Stream

Stephen5841

Hello everyone! Allow me to introduce my DIY stream. I plan to connect a timer to it and run it like a Wavebox while searching for radio parts. Specifications: 24V motor, 5000 RPM, height 250mm, chamber diameter 70mm, intake and outlet 32mm, impeller from Atman 4000 with slightly modified blades, acrylic shaft 12mm. It operates silently, with a faint, if you can call it that, hum from the motor. Next to it is a Rezansky 15000 stream, which simply "rests" in terms of performance; I am very pleased with the result, the motor is out of the water and does not heat it. Photos attached.

and how about the noise level

Cool How many watts does it have? What kind of engine is it - is it designed for long-term use???? Is there no overheating??? How did you make the shaft support??? Materials?

Everything is fine, but the brushes in the engine fall off after a couple of months of operation.

Everything new is well-forgotten old. The product of the Soviet aquaculture industry is the external pump STRUMOK. Long ago, when there was a problem with pumps, I tried this design. The idea is good, but there is a major drawback – moisture gets into the motor. As a result, the bearing wears out quickly, there is an imbalance in the rotor, vibration, and noise. In the end, it worked for about a year. The lifespan can be extended by periodically lubricating the bearing.
