Working principle of hydraulic gear pump

The working principle of gear pump is: two gears with the same size mesh and rotate in a closely matched shell, and the inside of the shell is similar to an "8" shape. Two gears are installed inside, and the outer diameter and two sides of the gears are closely matched with the shell.

The gear pump is driven by an independent motor, which can effectively block the upstream pressure pulsation and flow fluctuation. The pressure pulsation at the gear pump outlet can be controlled within 65438 0%.

The use of gear pump in extrusion production line can improve the flow output speed and reduce the shearing and residence time of materials in extruder.
