Rotor shaft has a small pit how to do?

Rotor shaft has a small pit solution: 1. Use an angle grinder to grind the gouging cleaning part and the edge of the defect until the metal luster is exposed, and the welding repair can be carried out after confirming that there are no defects. 2. Welding repair. The transition layer welding current is about 90A, short arc welding, small current, fast welding, narrow weld bead, electrode does not swing, reduce heat and heat affected zone width, improve weld intergranular corrosion resistance and reduce the tendency of hot cracking. 3,. Cleaning and inspection after welding. After welding, remove the coating, slag, weld bead, etc.

What does turbo mean?

A turbocharger (Tubro) is actually an air compressor. It uses the exhaust gas from the engine as power to push the turbine in the turbine chamber (located in the exhaust duct), and the turbine drives the coaxial impeller in the intake duct?, The impeller compresses the fresh air sent by the air filter pipe, And then sent to the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase simultaneously, and the degree of air compression is increased, and the intake air volume of the engine is increased accordingly, and the output power of the engine can be increased.
