Beautifully crafted leather products.

In the water conservancy project, the connection between the Rolling Wheel and the gate is completed by the wheel shaft, to make the roller rotate with as little friction resistance as possible, the roller is equipped with a self-sliding bearing in the shaft hole. Graphite plugged self-lubricating bearing can meet the high load, lubrication difficulties or can not be lubricated, high-temperature work, and other harsh working conditions.

Structure Of Hydropower Self-lubricating Bearings

Hydropower Bearing is a self-lubricating bearing with a high-quality, high-strength copper alloy substrate with several holes. embedded solid lubricant in the holes. When the bearing is working, the solid lubricant forms a very thin and smooth lubricating film on the bearing surface to achieve self-lubrication. After shutdown, it can reduce the direct contact between the metal of the friction pair, to reduce the resistance to restart, even under very high load, and it can also achieve very good results.

Specialized Solutions for Hydropower

  • Self-lubricating, avoiding water contamination

  • Dry running – important for pump start-up and priming

  • Low coefficient of friction eliminates vibration and stick-slip effects

  • Long life with little downtime.

Bearings for Hydropower

Hydropower bearings are specialized mechanical components used in hydropower plants to support and guide rotating machinery, such as turbines, generators, and shafts. These bearings allow the equipment to operate efficiently and with minimal friction, ensuring smooth and reliable energy production.

High-Performance Hydropower Self-Lubricating Bearings

Types of Bearings Used in Hydropower Plants

  • Thrust bearings are designed to handle axial loads generated by the weight of the rotating machinery and the water pressure on the turbine runner. They help maintain the proper position of the rotating parts and ensure that the force is evenly distributed.

  • Journal bearings support radial loads and are used primarily to support the weight of the rotating shafts. They allow for smooth rotation of the shaft while minimizing friction and wear, ensuring efficient energy transfer from the turbine to the generator.

  • Guide bearings, also known as radial or sleeve bearings, are responsible for guiding and maintaining the alignment of the rotating shafts. They prevent lateral movement and keep the shafts stable during operation.

  • Long life with little downtime.

Key Components And Materials Of Hydropower Bearings

Bearing pads are the primary contact point between the rotating shaft and the bearing. They help distribute the load and minimize friction. Depending on the type of bearing, they can be made from a variety of materials, including Babbitt metal, bronze, or high-performance polymers.

Bearing Materials

The choice of bearing material is crucial for the performance and durability of hydropower bearings. Some of the most common materials include Babbitt metal, bronze, and self-lubricating polymer-based materials. Each material has its advantages and disadvantages, depending on the specific application and environmental conditions.

Water Gates Application -Bearing Bronze With Graphite Inserts

Water gates are essential components of water management systems. They are used to control the flow of water, whether for irrigation, flood control, or hydroelectric power generation. To ensure the efficient operation of water gates, it is important to use high-quality materials for their construction.

Bearing bronze with graphite inserts is an excellent material for water gates application. wear resistance, underwater, portability, and ease of assembly and operation. These inserts provide continuous lubrication over the entire sliding surface. Additionally, these zero-pollution bearings eliminate the possibility of water contamination by removing the need for toxic lubrication.
