Application of JDB self-lubricating bearings in plane gate travel supports

JDB self-lubricating bearings produced by Mingxu Machinery are widely used in plane gate travel supports, and their characteristics and advantages are remarkable. The following is a detailed analysis of the application of JDB self-lubricating bearings in plane gate travel supports:

Characteristics of JDB self-lubricating bearings
1)Self-lubricating performance: JDB self-lubricating bearings can work without external lubrication. By embedding solid lubricants on the bearing matrix, an extremely thin and smooth lubricating film is formed, thereby reducing the direct contact between the friction pair metals and reducing the opening and closing resistance.
2)High strength and excellent friction resistance: JDB self-lubricating bearings use high-quality high-strength copper alloy as the matrix material, with high tensile strength, yield strength and hardness, and can withstand large loads and friction.
3)Wear resistance: After multiple indoor simulated wear tests of turbines and real machine applications, JDB self-lubricating bearings have the advantages of wear resistance, low friction coefficient, high load capacity and no damage to the dual wear parts.
4)Wide application conditions: JDB self-lubricating bearings can work under conditions such as heavy load, low speed (even ultra-low speed), high temperature, etc. where lubricating oil film cannot be formed, and can also effectively deal with impact loads that are prone to occur during work.

Application advantages of JDB self-lubricating bearings in plane gate travel supports
1)Reduce the opening and closing force and the lifting weight of the opening and closing equipment: Since JDB self-lubricating bearings have excellent self-lubricating properties and wear resistance, they can significantly reduce the friction resistance of the plane gate during the opening and closing process, thereby reducing the opening and closing force and the lifting weight of the opening and closing equipment.
2)Improve equipment operation efficiency: Reduced opening and closing force and lifting weight of the opening and closing equipment mean lower energy consumption and higher equipment operation efficiency, which helps to reduce the operating cost of hydraulic metal structures.
3)Extend equipment service life: The wear resistance of JDB self-lubricating bearings can effectively reduce equipment wear and damage, thereby extending the service life of the equipment and reducing maintenance and replacement costs.
4)Simplify the lubrication system: The self-lubricating characteristics without external lubrication make JDB self-lubricating bearings do not require a complex lubrication system in the application, reducing the complexity and maintenance difficulty of the equipment.
Application Examples
Take a reservoir as an example. The flat-plate emergency maintenance gate at the entrance of the water supply power generation tunnel adopts JDB self-lubricating bearings as the support form. The gate opening size is 3.4m×3.4m, the design head is 27.9m, and the support form uses 4 sets of self-lubricating bearings with simple support wheels, and the maximum wheel pressure reaches 865kN. This application example fully proves the reliability and effectiveness of JDB self-lubricating bearings in the travel support of plane gates.

In summary, the application of JDB self-lubricating bearings in the travel support of plane gates has significant advantages and wide applicability. Its self-lubricating performance, high strength and excellent friction and wear resistance enable it to maintain a good working condition under harsh working conditions such as heavy load, low speed and high temperature, effectively improving the operation efficiency and equipment service life of the plane gate.
