Description
The technical field is as follows:
the utility model relates to the field of hydraulic generators, in particular to a novel structure of a hydraulic generator follow-up and limit combined sealing oil baffle;
background art:
when the hydroelectric generating set operates, an upper guide bearing, a lower guide bearing and a thrust bearing of the hydroelectric generating set are required to be in direct contact with a rotor sliding rotor along with the rotation of the rotor, so that the stable operation of the hydroelectric generating set is ensured. When in contact, heat is generated due to friction, and the generated heat needs to be conducted by using lubricating oil in oil grooves inside the three supporting structures. Because hydroelectric set's high-speed rotation, can make the inside partial lubricating oil of oil groove form the oil mist in the operation process. If the oil mist is separated from the oil groove, the oil mist can be condensed on the surface of the stator and the rotor to pollute an insulating layer, so that the safe operation of the water-turbine generator set is endangered. The sealing oil baffle with the traditional structure can gradually lose the effect along with the increase of the running time of the unit, and the requirement of safe running of the unit cannot be met.
The invention content is as follows:
the utility model provides a both can effectually block the oil mist, still can greatly prolong sealed tooth life's hydraulic generator follow-up and limit combined seal oil fender novel structure, technical scheme is: consists of a metal oil baffle (1), a follow-up contact type self-lubricating insulating seal tooth (2), a zero-clearance self-lubricating insulating seal tooth (3), an upper cavity (4), a lower cavity (5), an oil baffle groove (6) and a seal tooth convex groove (7), from top to bottom, two layers of follow-up contact type self-lubricating insulating seal teeth (2), two layers of zero-clearance self-lubricating insulating seal teeth (3) and two layers of follow-up contact type self-lubricating insulating seal teeth (2) are sequentially arranged, an oil baffle groove (6) is processed on the metal oil baffle (1), a seal tooth convex groove (7) corresponding to the metal oil baffle (1) is processed on the follow-up contact type self-lubricating insulating seal teeth (2) and the zero-clearance self-lubricating insulating seal teeth (3), the servo contact type self-lubricating insulating seal tooth (2) and the zero-clearance self-lubricating insulating seal tooth (3) are fixed in the metal oil baffle (1) through springs on the backs of the self-lubricating insulating seal tooth.
The metal oil baffle (1) is divided into an upper cavity (4) and a lower cavity (5) and is made of cast aluminum alloy.
The follow-up contact type self-lubricating insulation seal tooth (2) is composed of a high-molecular wear-resistant self-lubricating material, one side of the follow-up contact type self-lubricating insulation seal tooth is installed in the metal oil baffle (1), the other side of the follow-up contact type self-lubricating insulation seal tooth is in contact with a shaft, has 0.5-1mm of compression amount with the shaft, and is made of the self-lubricating insulation material.
The zero-clearance self-lubricating insulating seal tooth (3) is made of a high-molecular wear-resistant self-lubricating material, one side of the zero-clearance self-lubricating insulating seal tooth is installed in the metal oil retainer (1), and the other side of the zero-clearance self-lubricating insulating seal tooth is in contact with a shaft without compression.
The zero-clearance self-lubricating insulating seal tooth (3), the upper cavity (4) and the lower cavity (5) form a whole.
The technical effects are as follows:
1. compared with the traditional structure, the utility model discloses a multilayer seal structure, from the top down counts multilayer follow-up contact self-lubricating insulating sealing tooth area 0.5-1mm compressive capacity and axle contact, zero clearance seal self-lubricating insulating material and the laminating of axle zero clearance altogether, can very effectual prevention oil mist spill over the oil groove.
2. The utility model discloses stable in structure can long-term effectual prevention oil mist spill over the oil groove, and self-lubricating insulating seal tooth adopts macromolecular material, can not cause the damage to the counter shaft. And the self-lubricating insulating seal tooth of the oil shield is convenient to detach and install, simple in structure and not easy to damage.
