Technical Field

[0001] The utility model relates to the technical field of gear pumps, in particular to an energy-saving hydraulic gear pump. 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 closed spaces consisting of two gears, a pump body, and 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 in the liquid, 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.

[0003] In the prior art, when using a gear pump, it needs to rely on electricity resources for power supply. However, if it relies solely on thermal power resources for power supply, the gear pump consumes a lot of electricity during operation, resulting in high operating costs of the gear pump. To this end, we propose an energy-saving hydraulic gear pump. Utility Model Content

Through the meshing action of the active bevel gear and the driven bevel gear, the rotating column can be driven to rotate by rotating the adjustment handle. The elastic action of the spring makes the clamping plate close to the surface of the box cover, thereby improving the stability of the solar panel. The clamping plate is driven to leave the box cover by the toggle block, so that the solar panel can rotate around the rotating column with the mounting base. The orientation angle of the solar panel is adjusted according to the position of sunlight.
