Working principle of high viscosity gear pump

The working principle of high viscosity gear pumps mainly depends on the working mode of positive displacement pumps, which achieves the transportation of high viscosity liquids through the rotation of gears. When the gear pump starts working, the active gear shaft rotates together with the motor reducer, driving the passive shaft to rotate. On the suction side of the pump, the meshing teeth gradually separate, increasing the volume of the suction chamber and forming a low-pressure zone. At this point, the high viscosity liquid is sucked into the tooth groove inside the pump body. As the gear continues to rotate, the liquid is carried to one side of the discharge chamber. When the two gears mesh again, the liquid in the tooth groove is squeezed out of the discharge chamber and pressed into the outlet pipe. During this process, as long as the pump shaft continues to rotate, the gear will continuously push the liquid towards the outlet side, so the pump outlet can reach a high pressure. In addition, the structure of high viscosity gear pumps typically includes pump casing, front and rear side covers, gear shaft, sliding bearings, and shaft seals, which work together to ensure efficient and safe delivery of high viscosity liquids
