A wicket gate bearing is a crucial component in hydroelectric power systems. Produces various self-lubricating materials for bearings, including plastics, metal, and bronze/brass bushing, wicket gate bushing offer self-lubricating mechanism under wet/dry application.
Bushings and wear pads are essential components in hydropower units, particularly in the wicket gate mechanism of hydro turbines. They are used to reduce friction and wear, ensuring the long life of the turbine components. Initially, cast iron bushings were used, which were later replaced with greased bronze bushings due to their improved performance. Greased bronze bushings have a high resistance to water washout, high load carrying capacity, and vibration damping, making them suitable for wicket gates. However, greased bushings require regular maintenance and can pose environmental issues due to the leakage of grease into waterways.
In recent years, greaseless bushings have been developed to address these concerns. These bushings can be classified into two groups: metallic and non-metallic. Metallic bushings are usually bronze-based, with anti-friction and dry lubricant compounds dispersed on the bearing surface. Non-metallic bushings are typically plastic or composite materials with anti-friction compounds on the bearing surface, with PTFE being the most prevalent material used for anti-friction.
The primary advantage of greaseless bushings is their reduced need for lubrication and maintenance. They are suitable for a wide range of temperatures and can function without external energy sources, saving energy costs. However, greaseless bushings have a higher failure rate compared to greased bushings, with an estimated failure rate of 25%
Bushings and wear pads play a crucial role in the performance and longevity of hydropower units. While greased bushings have proven to be reliable, greaseless bushings offer advantages in terms of reduced maintenance and energy savings. The choice between greased and greaseless bushings depends on the specific application requirements, considering factors such as load, temperature, speed, and environment.
The Evolution and Applications of Bushings in Hydro Units
In the realm of hydroelectric power generation, bushings, bearings, and wear pads play a pivotal role in ensuring the smooth operation of a hydro turbine’s wicket gate mechanism. This article delves into the evolution, uses, and advancements in the technology of bushings, particularly focusing on the transition to self-lubricating bearing bushes.
Historical Context and Traditional Materials
Historically, over a century ago, bushings in hydro turbines were predominantly made from cast iron, a material that inherently contains embedded graphite, which provides some level of self-lubrication. These bushings would operate against steel surfaces, with water flow through the turbine assisting in lubrication. However, as technology progressed, the introduction of grease and anti-friction materials like bronze significantly reduced wear and enhanced the durability of these components.
Bronze Bushings: A Reliable Choice
Bronze has become a material of choice for bushings in the hydro sector, particularly the tin bronze family, due to its favorable properties. These include a low tendency to adhere to steel, high load-carrying capacity, excellent corrosion resistance, and the ability to provide superior protection to the journals they interact with. To optimize their performance and longevity, these bronze bushings require proper lubrication, typically achieved through oils, greases, or solid lubricants.
Grease, in particular, stands out as a preferred lubricant for wicket gates, owing to its resistance to water washout, its ability to carry high loads, and its vibration damping properties. Unlike ordinary oils, lubricating greases contain thickening agents that enable them to stay in place and provide consistent lubrication even under challenging conditions.
Advances in Self-Lubricating Bushings
The evolution of bushing technology has led to the development of greaseless or self-lubricating bushings. These innovative components are designed to reduce maintenance needs and provide reliable service in environments where lubrication might be challenging. They fall into two main categories:
-
Metallic Bushings: Typically made from bronze, these bushings incorporate anti-friction and dry lubricant compounds such as PTFE (polytetrafluoroethylene) or molybdenum disulfide directly on the bearing surface. The integration of these materials allows for reduced friction and wear without the need for additional lubrication.
-
Non-Metallic Bushings: These are generally composed of plastic or composite materials, with anti-friction compounds applied to the bearing surface. PTFE is a common choice for its low coefficient of friction, complemented by other materials like molybdenum disulfide and graphite for enhanced performance.
Practical Applications and Selection
In hydroelectric power plants, the choice of bushing material and type is critical and often based on the specific conditions and requirements of the turbine and its environment. For example, polymer-lined bushings may be favored for their resistance to abrasive particles like silt in river units, while plugged bronze bushings might be preferred in high-load applications due to their robustness.
It’s crucial to note that while greaseless bushings offer the advantage of reduced maintenance, they are designed to wear gradually as part of their operation. The wear process for plugged bronze bushings involves the gradual erosion of the plug material to release the lubricant, while polymer and composite bushings rely on the inherent low friction of their materials.
Conclusion
The ongoing advancements in bushing technology underscore the hydro industry’s commitment to improving efficiency and reducing maintenance demands. Self-lubricating bushings represent a significant step forward, offering durable and reliable solutions that cater to the unique demands of hydroelectric power generation. As these technologies continue to evolve, they promise to play a vital role in the sustainable and efficient operation of hydro units worldwide.
