The role of the excavator gear pump is to generate pressure in the liquid through a change in volume, thereby converting mechanical energy into hydraulic pressure energy for hydraulic transmission and control.
The excavator gear pump is a type of positive displacement rotary pump that relies on the change and movement of the working volume formed between the pump chamber and the meshing gears to transport or pressurize the liquid. Specifically, the gear pump consists of two gears, a pump body, and front and rear covers that create two enclosed spaces. As the gears rotate, the volume of the space on the disengaged side of the gears increases, creating a vacuum that draws in the liquid. Conversely, the volume of the space on the meshing side decreases, forcing the liquid into the pipeline. This working principle allows gear pumps to transport liquids with lubricating properties, such as fuel oil and lubricating oil.
Gear pumps play a crucial role in excavators and other engineering machinery. They are not only used in simple hydraulic systems but are also widely employed in lubrication systems as auxiliary oil pumps. Due to their simple structure, ease of manufacturing, low cost, and good adaptability to lubricating liquids, gear pumps have become an indispensable component in equipment like excavators. Additionally, the outlet pressure of the gear pump is entirely dependent on the resistance at the pump outlet, allowing it to maintain stable performance under various working conditions.
