The vane hydraulic pump is a volumetric pump, which is used quite widely, mainly in low and medium pressure systems. The pump is suitable for oil supply systems for machine tools.

 

Single-acting vane pump ie corresponding to 1 rotation cycle, the pump can perform 1 suction and 1 push.

Single-acting vane pumps usually have 4-12 impellers and the more the number of veneers, the more evenly pumped.
Working principle of single vane pump: When the single vane pump connects to the power supply and starts operating, the pump control shaft begins to move, causing the rotor to rotate. Since the single vane pump has the pump housing center and the rotor is spaced apart, when the rotor rotates the plates slide in the grooves and the wiper moves.

Double vane pump that corresponds to 1 rotation cycle of pump with 2 suction and 2 pump push.
Working principle of double-acting vane pump
Similar to the double-acting vane pump, the single-acting vane pump starts operating when the power is connected, the motion-controlled shaft rotates the rotor. The suction process of a double-acting vane pump is similar to that of a single-acting vane pump with the principle that the rotor is always mounted eccentrically from the pump chamber in a cycloid pattern, with the center of the rotor coinciding. with mind shell.
The difference in the working principle of a single-acting vane pump and a dual-acting vane pump is that in one duty cycle the pump must perform two suction and two pushes.
