SF-2 composite bearing is like a shining pearl, with its excellent performance and reliable quality, escorting the stable operation of all kinds of equipment, and becoming one of the key core components of the hydraulic machinery industry.
Performance Advantages
- Excellent wear resistance: SF-2 composite bearing adopts multi-layer composite material structure, and the modified polyformaldehyde and other polymer materials in the surface layer have extremely high wear resistance. In the complex operating environment of hydraulic machinery, such as the guide vane bushings, connecting rod pins and other parts of hydraulic turbines, which are subject to long-term water impact and mechanical friction, this high wear resistance can effectively reduce the wear of the bearings, ensure the precision and performance of the equipment is durable and stable, and prolong the service life of the bearings.
- Good self-lubricating performance: The working environment of hydraulic machinery is often wet, and traditional lubrication methods may face problems such as emulsification and loss of grease. SF-2 composite bearings have good self-lubricating performance due to its special material formula, and its surface material can form an effective lubrication film in the friction process to reduce the friction resistance, which can maintain stable lubrication effect even in the harsh working conditions such as underwater, and reduce the maintenance cost and downtime of the equipment.
- High fatigue strength: Bearing parts in hydraulic machinery need to withstand frequent starting, stopping and alternating loads, SF-2 composite bearings use low carbon steel as the base layer and copper powder as the middle layer, which is a structural combination that gives the bearings very high fatigue strength. Take the push-pull rod pin of hydraulic turbine as an example, it can resist the fatigue stress generated by load changes during the long-term operation of the equipment, avoiding fatigue cracks and ensuring the safe and reliable operation of the equipment.
- Excellent corrosion resistance: in the hydraulic environment, dissolved oxygen, impurities in water, and acidic and alkaline substances may cause corrosion to the bearings, and the surface material of SF-2 composite bearings has good corrosion resistance, which can resist these corrosive factors, maintain the dimensional accuracy and mechanical properties of the bearings, adapt to the complex water-chemical
- environment of the hydraulic machinery, and reduce the equipment failures caused by corrosion.
Application examples
- Hydraulic turbine guide vane sleeve: In the water guiding mechanism of hydraulic turbine, the guide vane sleeve is one of the key components. The guide vane sleeve installed with SF-2 composite bearing can withstand the friction and water pressure generated during the opening and closing process of the guide vane to ensure flexible and stable movement of the guide vane. Its good self-lubricating performance and corrosion resistance enable it to maintain a good running condition even under long-term contact with water flow, which effectively improves the operating efficiency and reliability of the hydraulic turbine and reduces the maintenance cost.
- Hydraulic Turbine Push-Pull Pin: The push-pull pin plays the role of transmitting force in the regulation system of the hydraulic turbine, and is subject to large radial and axial loads during operation, SF-2 composite bearing is applied to the push-pull pin, and its high strength and fatigue-resistant performance can meet the requirements of the hydraulic turbine under the frequent regulation conditions to ensure the accuracy and reliability of the regulation system, so as to ensure the stable output of the turbine and the safe operation, and provide strong support for the stable power generation of the hydropower station. This ensures the stable output and safe operation of the hydraulic turbine, and provides strong support for the stable power generation of the hydropower station.
- Water conservancy valve parts: SF-2 composite bearings are often used for the bearing parts between the valve stem and the valve body of various valves in the water conservancy system, such as butterfly valves, ball valves, etc. The bearings can be used in the frequent opening and closing of the valves. The bearing is able to open and close the valve frequently in the process, to withstand the friction torque and water pressure difference, its low coefficient of friction and good corrosion resistance, so that the valve operation is flexible, lightweight, prolonging the service life of the valve, reducing the maintenance workload of the water conservancy system, to ensure the normal operation of irrigation, water supply and drainage projects.
