Introduction:
The sealing of motor bearings belongs to dynamic sealing, with the fundamental goal of preventing oil leakage. The improved "polyimide process floating sealing ring" developed by Zhanggui solves the leakage problem of traditional floating sealing rings in China that cannot work in high temperature, high speed, high vacuum, and radiation environments for a long time due to production process, material, and structural issues.
Polyimide labyrinth floating seal ring motor oil seal adopts aerospace industry thermoplastic engineering polyimide materialPI-YS20It has excellent characteristics such as high insulation, wear resistance, self-lubricating, high temperature resistance, stable product size, and no wear on the shaft, and is applied to the sealing of sliding bearings for large and medium-sized motors.
Structure and application of polyimide labyrinth floating sealing ring:
1The polyimide labyrinth floating seal ring is a two half ring structure consisting of a return oil hole, a positioning pin, and a spring groove;
2The labyrinth floating sealing ring has four slots in the inner ring and one slot in the outer ring for clamping the spring;
3There are three circular holes in the positioning pin position and three circular holes in the opposite position, with the remaining circular holes serving as oil return grooves.
The product is suitable for various specifications of generator equipment, desulfurization and denitrification equipment, various power station auxiliary equipment, and AC/DC motors. The product is widely used in industries such as coal mining, smelting, petrochemicals, and power generation. Now it has become the designated matching sealing ring for large motor and bearing manufacturers such as Shanghai Electric Machinery Factory, Nanyang Explosion proof, Jiamusi Electric Machinery, Zhejiang Shenke, Zhejiang Zhuji Bearing, Hunan Chongde, etc.
