Description

Technical Field

[0001] The utility model belongs to the technical field of gear pumps, in particular to a gear pump base with high stability effect. Background Art

[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 front and rear covers to form two closed spaces. When the gears rotate, the volume of the space on the side where the gears are disengaged changes from small to large, forming a vacuum to suck in the liquid, and the volume of the space on the side where the gears are meshing changes from large to small, squeezing the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. The pressure at the discharge port of the gear pump depends entirely on the size of the resistance at the pump outlet.

[0003] When the gear pump is working, it is mostly installed on the base. However, due to the different specifications and sizes of the gear pump, the existing gear pump base is difficult to adjust according to the different sizes of the gear pump. Therefore, the gear pump base has certain limitations, which greatly reduces the application scope of the gear pump base. Utility Model Content
