A gear structure pump, also known as a gear pump, is a type of positive displacement pump that uses the meshing of gears to pump fluid. It operates on the principle of trapping fluid between the teeth of two rotating gears and transferring it from the inlet to the outlet of the pump. Here's an overview of its structure and operation:

1. Structure:

   • Gear pumps consist of two interlocking gears—usually spur gears or helical gears—enclosed within a pump housing or casing.
   • The gears are mounted on parallel shafts and rotate in opposite directions within the pump housing.
   • The teeth of the gears mesh closely together, forming a seal along the gear faces and the pump casing.
   • The pump housing contains inlet and outlet ports, as well as internal passages for fluid flow.

2. Operation:

   • Fluid enters the pump through the inlet port and fills the space between the gear teeth on the inlet side.
   • As the gears rotate, the fluid is carried around the outside of the gears in the spaces between the teeth.
   • The fluid is then squeezed between the gear teeth and the pump casing, creating a positive displacement action that pushes the fluid out through the outlet port.
   • The meshing of the gears ensures a continuous and uniform flow of fluid through the pump.
   • The rotation of the gears creates a low-pressure area on the inlet side of the pump, causing fluid to be drawn into the pump. Conversely, a high-pressure area is created on the outlet side, forcing fluid out of the pump.

3. Features:

   • Gear pumps are known for their simplicity, reliability, and efficiency. They have a compact design and are capable of generating high flow rates at moderate to high pressures.
   • They are self-priming and can handle a wide range of fluids, including viscous liquids, chemicals, oils, and fuels.
   • Gear pumps are available in various configurations, including external gear pumps, internal gear pumps, and gerotor pumps, each offering specific advantages and applications.
   • Some gear pumps incorporate features such as adjustable clearances, hardened gear materials, and bypass valves to enhance performance and durability.

4. Applications:

   • Gear pumps are widely used in various industries, including automotive, chemical processing, food and beverage, pharmaceuticals, and hydraulic systems.
   • Common applications include lubrication systems, hydraulic power units, fuel transfer systems, chemical dosing, and metering applications.
   • They are often employed in situations where precise flow control, reliable operation, and compact size are required.

In summary, a gear structure pump, or gear pump, is a versatile and efficient positive displacement pump that utilizes the meshing of gears to transfer fluid from the inlet to the outlet. Its simple design, reliability, and versatility make it suitable for a wide range of industrial applications.
