Gear pump, the pump body is made of 304 material, the main gear shaft is also made of 304 material, the pump flow rate is 0.6m3/h, the pressure is 0.6Mpa, the inlet and outlet diameters are both 25mm, the motor power is 0.75kw, and the motor speed is 960r /min. The structure of the arc gear oil pump is mainly composed of gears, shafts, pump bodies, pump covers, bearing sleeves, and shaft end seals. The gear is made of double-arc sinusoidal tooth profile. Compared with involute gears, its most prominent advantage is that there is no relative sliding on the tooth profile surface during gear meshing, so the tooth surface has no wear, stable operation, no fluid phenomenon, low noise, long life and high efficiency. The pump gets rid of the shackles of traditional design, making the gear pump enter a new field in design, production and use.
