The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsional loads.

[0004] Therefore, the crankshaft is required to have sufficient strength and rigidity, the journal surface needs to be wear-resistant, work evenly and have good balance. The crankshaft needs to be polished during production to remove burrs and spikes on the surface, further improve the roughness of the shaft diameter surface, make the crankshaft surface smoother and flatter, help reduce friction and wear, and increase the service life of the crankshaft; the flushing water used in the crankshaft polishing process will be mixed with metal impurities after the crankshaft is polished after flushing, and the flushing return water is mixed with metal impurities, which will damage the crankshaft surface during use. Therefore, a steady supply of clean flushing water is required to flush the crankshaft polishing process. A large amount of flushing water containing metal impurities will cause waste and pollution of water resources, and the metal impurities are not well recycled and reused. Utility Model Content
