Description

Technical Field

[0001] The utility model relates to the technical field of gear pumps, in particular to a gear pump for an ice cream machine. Background Art

[0002] Ice cream is one of the most popular desserts in summer, and making a cup of delicious ice cream is inseparable from an efficient ice cream machine. In ice cream machines, gear pumps are widely used. Gear pumps are a device used to transport liquids. Their special working method makes them an ideal choice for ice cream machines. Gear pumps inhale and discharge media through the rotation of gears. After the ice cream powder or milk slurry is sucked and ground by the gear pump, it is supplied to the ice cream machine, which significantly improves the taste of the ice cream.

[0003] 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. Existing gear pumps of this type are generally not conducive to reliable transmission drive when in use, and are not convenient for the stable transmission of various materials in the ice cream machine under the drive of the gear pump. The gear pump will generate a lot of vibration noise when running, which greatly affects the taste of the ice cream when the ice cream machine is out of ice cream and affects the quiet effect of the gear pump.
