how does a hydraulic gear pump work
hydraulic gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications.
Here’s a simplified explanation of how they work:
Intake: As the gears rotate, they create a vacuum at the pump inlet. This vacuum draws hydraulic fluid into the pump.
Fluid Transfer: The fluid is then carried around the outer edge of the gears between the gear teeth and the pump housing.
Discharge: When the gear teeth mesh again at the pump outlet, the fluid is squeezed out, creating pressure and flow.
Key Features of Gear Pumps:
Simple Design: Gear pumps are relatively simple in design, making them reliable and easy to maintain.
Compact Size: They are compact in size, making them suitable for applications with space constraints.
Cost-Effective: Gear pumps are generally less expensive than other types of hydraulic pumps.
Applications:
Hydraulic gear pumps are widely used in various industries, including:
Mobile equipment (excavators, loaders)
Industrial machinery (presses, injection molding machines)
Agricultural equipment (tractors, harvesters)
Automotive (power steering systems)
