Description

Technical Field

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

[0002] A gear pump is a pump that uses gear transmission to transport liquids or compressed gases. It is usually composed of two meshing gears, one of which drives the other gear to rotate, thereby generating the movement of sucking in and discharging liquid or gas. Gear pumps are usually used in the fields of liquid transportation, lubricating oil circulation, pressure transportation, and liquid pressurization. It has the characteristics of simple structure, large flow rate, and stable pressure, so it is widely used in industry and mechanical equipment. In the use of existing gear pumps, there are at least the following disadvantages: some existing gear pumps are affected by the use scenario, and often do not set a base on the pump body, resulting in a single use scenario for this gear pump without a base. Once disassembled, it cannot adapt to other use scenarios. Therefore, we have launched a lubricating gear pump. Utility Model Content
