The proposal is to use the Magnetically-Driven Archimedes Spiral Screw as a fluid mover for the Ultra-Long Life, Ultra-Low Wear Pumps.
So-called magnetic drive seal-less centrifugal pump is an established technology in heavy industrial applications for use with acids, alkalis, caustics, bleaches, sea water, solvents, etc. There is no metal contact with the liquid being pumped. Since the pump is magnetically driven, no shaft seal is required. Power is transmitted by a magnetic field from the magnet attached to the motor through the solid body of the pump to the magnet attached to the impeller. With no shaft seals, there are no seal or liquid leaks.
The impeller used in the conventional centrifugal pump causes turbulent flow with high level of noise and vibration, and may create cavitation which leads to short life and high wear of the pump mechanism.
The project will greatly simplify and miniaturise the magnetic drive seal-less pump for use in computer-related equipment, with an Archimedes Spiral Screw as a rotor. This combination will significantly extend the operating life of pumps by reducing pump wear, and realise a maintenance-free cooling system with a long period of continuous operation. There will be no bearing, no valve, no shaft seal.
The helical vane is the only moving part. It will minimise the turbulent flow, and keep the flow as laminar as possible. Thanks to the smooth operation, the lifetime of the components will be extended. A rare-earth magnet is embedded in plastic inside the helical vane on the rotor, which will be enclosed in a fused or welded injection-moulded plastic casing for ultra-high reliability.
The unique edge-activated shaft-less configuration results in ultra-compact design that fits into a required package. The motor itself is brush-less alternating-polarity electromagnet with no moving parts on the stator side.
The Magnetically Erected Wind-Effect Display Device (Canadian Patent 2 327 490) has demonstrated the effectiveness of the helical vane in moving fluid.
