Working principle of double-acting vane pump

The method is similar to the single-acting vane pump, except that the stator surface consists of two sections of long-radius arcs, two short-radius arcs and four transition curves, and the stator and the rotor are concentric. In the case where the rotor is rotated in the clockwise direction, the volume of the sealing working chamber gradually increases in the upper left corner and the lower right corner, is the oil absorption region, is gradually reduced in the lower left corner and the upper right corner, is a pressure oil region, and a section of sealing oil region is arranged between the oil suction region and the pressure region to separate them. The rotor of such a pump is rotated one revolution, and each sealing working chamber completes two operations of oil absorption and oil pressure, so it is called a double-acting vane pump. Two of the pumps The oil suction region and the two pressure regions are radially symmetric, and the liquid pressure acting on the rotor is balanced radially, so that it is also referred to as a balanced vane pump.
