As further improvement of the utility model, between described upper ring cap and lower ring set, leave the first gap, described
Upper magnetic ring and lower magnet ring between leave the second gap；In the application between upper magnetic ring and lower magnet ring and upper ring cap and lower ring set
Do not contact, between upper magnetic ring and lower magnet ring and do not rub between upper ring cap and lower ring set, further improve hydrodynamic
Efficiency.
As further improvement of the utility model, the width in the first described gap and the second gap is equal；Between first
Gap and the second gap width are equal, it is simple to install and manufacture.
As further improvement of the utility model, the width in the first described gap is 0.5-1.5mm.
As further improvement of the utility model, the width in the second described gap is 0.5-1.5mm.
In the application, the distance in the first gap and the second gap sets between son 0.5-1.5mm, and convenient installation, by reality
Checking, if this gap reduces again, has friction between upper magnetic ring and lower magnet ring and upper ring cap and lower ring set, affects hydrodynamic(al)
The efficiency of power, if this gap is more than 1.5mm, the repulsive force between upper magnetic ring and lower magnet ring is less, is not enough to offset the hydraulic turbine
And the hydraulic turbine rotates the blast producing.
Further improve as of the present utility model, described rotating shaft is provided with adjusting pad, described adjusting pad
The end cap laminating of top and bearing, the top laminating of the bottom of adjusting pad and upper ring cap；Adjusting pad is set, is used for adjusting upper magnetic ring
And the size in gap between lower magnet ring, the size requirements according to gap between upper magnetic ring and lower magnet ring sets the thickness of adjusting pad,
As the gap between upper magnetic ring and lower magnet ring to increase, then select the adjusting pad that thickness is more relatively large, such as upper magnetic ring and lower magnetic
Require less gap between ring, then select the adjusting pad that thickness is smaller.
In sum, the beneficial effects of the utility model are: the application is arranged on the hydraulic turbine, upper magnetic ring and lower magnet ring it
Between the power downward pressure and the blower fan that hydraulic turbine driving fan is produced that repel counteract from gravity from gravity and impeller, therefore
As long as the hydraulic turbine just does the power of direction of rotation, without the active force axial from plane, and the radial direction decreasing bearing is subject to
Power, the hydraulic turbine will more easily rotate, say, that improves hydrodynamic utilization rate, adds the service life of bearing,
Improve the service life of the hydraulic turbine.
