[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport liquid or increase its pressure. It consists of two gears, a pump body, and two closed spaces formed by front and rear covers. When the gears rotate, the volume of the space on the gear disengagement side changes from small to large, forming a vacuum, sucking the liquid in, and the volume of the space on the gear meshing side changes from large to small, squeezing the liquid into the pipeline. Gear pumps are widely used in various industries such as mining equipment, metallurgical equipment, construction machinery, engineering machinery, and agricultural and forestry machinery.
