Description

Technical Field

[0001] The utility model relates to the technical field of gear pumps, in particular to a high-pressure spray gear pump. Background Art

[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume created between the pump cylinder and meshing gears to transport liquids or increase pressure. Two gears, the pump body, and front and rear covers form two enclosed chambers. As the gears rotate, the volume of the chamber on the disengaged side increases from smaller to larger, creating a vacuum that draws liquid in. The volume of the chamber on the meshing side decreases, squeezing the liquid into the pipeline. The suction and discharge chambers are separated by the meshing line of the two gears.

[0003] When the existing high-pressure gear pump is used in agriculture, a spray head is added to the liquid outlet to spray pesticides. When it is used in industry, such as oil transportation, the oil pipeline is fixed to the liquid inlet and liquid outlet of the high-pressure gear pump to transport the oil. When the gear pump is used to transport the oil, a large noise is generated when the two gears are meshed, resulting in a noisy environment in which the high-pressure gear pump is used, polluting the working environment of the workers and being detrimental to the use of the high-pressure gear pump.
