Hydroelectric equipment often works in harsh environments due to extremely high pressure and great friction with water flow, so ordinary metal components cannot guarantee long-term operation, but must use special alloys.   It is for this reason that it is extremely difficult to repair equipment such as stoppers, injectors, shafts, ...

For the lining of the sliding faces of hydrodynamic bearings, tin alloys are commonly used. An important criterion for the primer is to be applied free of foreign particles, having a higher hardness than the composition used. These unwanted particles can damage the shaft, the bearing as a whole, and ...

Damage to the drive shaft due to long-term wear is inevitable, but we have a solution to repair it domestically at a much lower cost thanks to modern methods such as Laser Cladding and PTA. . After welding hard alloy, this method also requires special machining solutions to achieve high ...
