Installation sequence and fault analysis of circular arc gear pump

Circular arc gear pump; The use of a point continuous contact gear, which is considered as a conveying pump, that is, a combination of double circular arcs and sine curves to form a tooth profile, can eliminate the use of involute gear conveying pumps. Has won major scientific and technological achievement projects and the third prize for scientific and technological progress from the Education Commission. The circular arc gear has a continuous contact point between the two meshing tooth profiles, which does not cause oil entrapment and solves the problems of vibration, noise, and increased bearing load caused by oil entrapment in involute gear pumps. Therefore, the circular arc gear pump has high efficiency, low noise, and energy-saving effect.
