The seven new patents support key elements of the SCS downhole artificial lift system, such as downhole liquid removal, seal-less downhole systems, downhole magnetic bearing systems, downhole generators, well optimization,
magnetic coupling integration and downhole measurement tools.
The protector-less design includes a permanent magnet motor that also acts as a
magnetic coupling.
A diverse variety of sealing options such as
magnetic coupling are available.
The final form of the equations of the mathematical model SRM, assuming no mutual
magnetic coupling between the phases is represented by the expressions:
Using
magnetic coupling (MAG-Drive), the SLW pump eliminates the need for mechanical seals and complex seal supply systems.
When these two conditions are both satisfied at the same time, the strong
magnetic coupling will occur and the readout distance will be significantly extended.
Third, we present the
magnetic coupling parameters obtained for the pure and the Mg-doped samples.
Magnetic coupling must to be strong enough to steady the device and deliver energy for sound conduction while not being so strong as to injure the interposed skin and soft tissue.
A novel technology for magneticfield mitigation: High
magnetic coupling passive loop.
Consistent with the multi-jet measurement principle, water flows through the WM-NLCH meter's strainer into the measuring chamber where it drives the impeller, which in turn drives the mechanical register dials by means of a
magnetic coupling. The impeller is the only moving part in contact with water, resulting in long life and consistently reliable operation.
