2. Structure and working principle of A70-FR07 and A70-FR09 series hydraulic pumps
The structure and working principle of A70-FR07 and A70-FR09 series hydraulic pumps are similar and are mainly divided into the following parts:
Drive shaft: The power input part of the hydraulic pump, which transmits the rotational power of the motor or engine to the interior of the hydraulic pump.
Rotor: The rotor is the core component of the hydraulic pump. It has blades and a cylindrical surface. The blades push the liquid from the low-pressure area to the high-pressure area. When the rotor rotates, the blades push the liquid from the oil inlet to the oil outlet, and the pressure at the oil outlet increases.
Stator: The stator is a fixed component of the hydraulic pump. Together with the rotor, it forms a sealed cavity. The size of the cavity changes with the rotation of the rotor, thereby pressurizing the liquid.
Discharge port: The discharge port of the hydraulic pump is the discharge channel for high-pressure oil, and the oil is transported to the downstream of the hydraulic system through the discharge port.
3. Application of A70-FR07 and A70-FR09 series hydraulic pumps
