Graphite type self-lubricating bronze bushes for repair and maintenance of hydropower components.

Hydropower components, such as turbines, experience high loads and constant exposure to water. This means they require bearings that can withstand these conditions while providing smooth operation. This is where graphite type self-lubricating bronze bushes come into play.

These bushes are constructed from high-strength cast brass, a material that exhibits excellent resistance to wear and tear, even under high-load and underwater conditions. This means they are particularly suited for use in the demanding environment of a hydropower plant.

What sets these bushes apart is their self-lubricating properties. They contain graphite inserts, a form of solid lubricant. Graphite is an excellent choice because it maintains its lubrication properties, even underwater. This significantly reduces friction between moving parts, enhancing the component’s performance and prolonging its lifespan.

PTFE (Polytetrafluoroethylene), another solid lubricant, can also be used either with or without lead. PTFE is a high-performance plastic known for its low friction, high melting point, and resistance to chemicals.

When integrated into the bronze bush, these solid lubricants eliminate the need for frequent manual lubrication, hence reducing maintenance costs and improving the operational efficiency of the hydropower facility.

In conclusion, using graphite type self-lubricating bronze bushes can be an effective strategy for maintaining and repairing hydropower components, ensuring they operate smoothly, efficiently, and with minimal need for maintenance.

self-lubricating bronze bushings, specifically with graphite inserts, for the repair and maintenance of hydropower components.

self-lubricating bronze bushings, specifically with graphite inserts, for the repair and maintenance of hydropower components. These components, such as lower stem bushes for wicket gates, are exposed to high load conditions under water. These bronze bushings are highly sought after in this context because of their notable wear resistance and durability.

The self-lubricating bearing is typically made from high strength cast brass, which demonstrates superior wear resistance even under high-load conditions underwater. The self-lubrication feature of the bearing comes from the solid lubricant used, which is often PTFE (Polytetrafluoroethylene), a high-performance plastic known for its low friction and high melting point. This lubricant can be either leaded or lead-free, depending on the specific application and regulatory requirements.

The purpose of the graphite inserts is to further enhance the self-lubricating properties of the bearing. Graphite has excellent lubrication properties and maintains these properties even when submerged in water, making it an ideal addition to the bearing for applications in hydropower facilities.

The combination of a high-strength cast brass base, PTFE solid lubricant, and graphite inserts make these self-lubricating bronze bushings particularly well-suited for hydropower applications, especially for components that are under high load and submerged in water. The self-lubricating feature of these bearings greatly reduces the need for regular maintenance, reducing costs and downtime.

Self-lubricating Bushing Bearing for Water turbine for Hydro Power

The 500SP bearing, often referred to as an “oilless” or “self-lubricating” bearing, can be an ideal choice for water turbine applications in hydroelectric power systems. This type of bearing is often composed of metal-polymer composite materials, which include a steel backing with a sintered bronze layer, and a PTFE-based sliding layer.

In a water turbine for hydro power, such bearings can have several benefits:

Maintenance-Free: As these bearings are self-lubricating, they don’t require additional lubrication. This reduces maintenance costs and downtime.

Corrosion Resistance: Given their composite nature and the inclusion of materials like bronze and PTFE, these bearings are inherently resistant to corrosion, which can be a significant benefit in a hydroelectric power environment where the bearing is in frequent contact with water.

High Load Capacity: These bearings are designed to handle high loads, a necessary feature given the substantial forces that can be exerted on a water turbine.

Reduced Friction: The PTFE-based sliding layer helps to minimize friction, enhancing efficiency and the lifespan of the turbine.

Tolerant to Misalignment and Edge Loading: These bearings can tolerate some degree of misalignment and edge loading, which can be beneficial in a turbine setting where precise alignment can be challenging.

Please note that when choosing bearings for such an application, it’s essential to consider factors like the operating conditions (including load, speed, and temperature), the surrounding environment, and the specific design of the turbine. It’s also important to consult with an engineer or a professional with expertise in hydroelectric power systems to ensure the selected bearing will meet your needs.

Hydro turbine bearing bushing manufacturers and suppliers

High-strength brass bearings with embedded solid lubricant can be an ideal choice for water turbines used in hydro power generation.

Gearbox rotor shaft in wind turbine systems, universal plain bearing material for both dry and lubricated applications.

Cylindrical plain bearing bushings, design ptfe metal composite bushings for wind and water power

Most wind turbine systems have a horizontally mounted 3-blade rotor. The wind rotates the rotor blades. The mechanical rotational motion is transferred from the rotor hub to the rotor shaft. The low speed of the rotor is converted to generator operation at a ratio of 1:25 through a gearbox. The rotor shaft is mounted on the hollow shaft of the gearbox in the input stage. The rotor shaft and the hollow shaft are connected at one side and rotate synchronously. Due to strong alternating stresses, the rotor shaft is twisted. This leads to a slight movement of the guiding parts. This strained contact point is usually subject to triple chemical corrosion.

Bearings with PTFE plain bearing bushings

The use of maintenance-free PTFE plain bearings prevents triple chemical corrosion and improves the quality of the guiding in the bearing position. Due to the low coefficient of friction of PTFE plain bearings, the negative effects from stick-slip are minimized.

Advantages: Reliable bearing function with PTFE plain bearings

  • Maintenance-free
  • Protected against triple chemical corrosion
  • Low running bearing clearance
  • Low wear, even under alternating stress
  • Low coefficient of friction
  • Material description

PTFE bushings are a versatile plain bearing material for dry and lubricated applications. This composite, multilayer material excels due to its high rigidity, durability, high chemical resistance and good emergency running characteristics. These properties are achieved in large part through the use of bronze lead sintered onto a steel base, as well as fluoropolymer PTFE and friction reducing additives of metallic lead.
