A hydraulic component gear pump is a common type of hydraulic pump that operates by rotating gears to吸入 liquid and compress it, thereby generating hydraulic energy. Gear pumps typically consist of two gears: a driving gear and a driven gear. The driving gear is powered by an electric motor or another power source, which drives the driven gear to rotate and generate hydraulic energy.

Gear pumps offer advantages such as simple structure, compact size, light weight, low noise, high efficiency, and good reliability. They are commonly used in low-pressure, medium to small flow hydraulic systems, such as construction machinery, agricultural equipment, ships, and aircraft. The disadvantages of gear pumps include susceptibility to liquid contamination and wear, necessitating regular replacement of hydraulic oil and other wearing parts.
