The previous part has introduce the use of the partial replacement method, transposition method and inserting method in matching of diesel generator set parts repair technology. We will continue introducing more information about this method in this post. Please find more information about repairing techniques of metal buckles for diesel generator sets.
Diesel generator set pressure processing repair parts are the use of external force to plastically deform the metal, restore the geometry of the part, or move the metal of the non-working part of the part to the worn part to compensate for the worn metal and restore the original working surface of the part. Size and shape. According to the plasticity of metal materials, it is divided into two types: cold press processing at normal temperature and hot press processing under hot state.
Welding repair of diesel generator set refers to the use of welding technology in the maintenance of generator equipment. Welding repair makes the matric and electrode powder melt together under the action of heat energy and get good intergranular bonding strength. However, the influence of heat energy will change the microstructure and shape of the matric, which is the key problem of welding repair.
The metal spraying of the diesel generator set uses a heat source to heat and melt the metal powder or the linear material, atomizes it into small metal particles by high-pressure, high-speed airflow, and sprays it onto the surface of the prepared part at a high speed of 100~300 m/s. A metal coating is formed. The sprayed coating is only mechanically adsorbed onto the substrate, while the base metal does not melt. Spraying is divided into oxygen-acetylene flame spraying, arc spraying, plasma spraying and explosive spraying according to the heat source used.
