The invention discloses a permanent magnet water-oil suspension sealing device completely reducing water turbine friction coefficient. The permanent magnet water-oil suspension sealing device comprises a spindle and a sealing device arranged from top to bottom by taking the spindle as a center, the sealing device comprises a sealing rotary ring, a rubber sealing ring and a sealing seat, the sealing rotary ring is arranged at the determined position of the spindle, the rubber sealing ring and the sealing seat are sequentially arranged downwards, a fixing cylinder externally sleeves the sealingring, the inner side wall of the fixing cylinder is fixedly connected with a positioning ring plate corresponding to the sealing seat, two L-shaped through holes are symmetrically formed in the upperend of the sealing seat, vertical portions of the through holes are rotatably connected with telescopic rods through ball bearings, the upper ends of the telescopic rods extend out of the through holes and are fixedly connected with rotary blocks, and fixing grooves corresponding to the rotary blocks are formed in the upper end of the sealing seat. The sealing seat is conveniently disassembled, assembled and used.
Description
technical field [0001] The invention relates to the technical field of water turbines, in particular to a permanent magnet water-oil suspension sealing device which completely reduces the friction coefficient of the water turbine. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy, and it belongs to the turbomachinery in fluid machinery. As early as around 100 BC, the prototype of the water turbine appeared in China - the water wheel, which was used to lift irrigation and drive grain processing equipment. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the turbine through the diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tail water ...
