The excavator hydraulic pump acts as the "heart" of the hydraulic system, converting engine mechanical energy into hydraulic power to drive actuators (e.g., cylinders, motors). Its core principle relies on the reciprocating motion of pistons within cylinders, cyclically altering chamber volume to suction and pressurize oil. As a variable-displacement pump, it dynamically adjusts output flow based on load demand, delivering stable high-pressure (35MPa+) power for precise digging force while optimizing energy efficiency.

Excavators are heavy machinery widely used in various fields such as construction, engineering, and mining. The main application areas include:

Construction engineering: Excavators are used for excavating foundation pits, cleaning sites, excavating underground facilities, foundation construction, etc.

Mining: In mines, excavators are used for mining ores, transporting materials, stripping topsoil, and crushing operations.

Water conservancy engineering: In water conservancy construction, excavators are used to excavate rivers, clear lakes, build dams and canals, etc.

In the field of agriculture, excavators are sometimes used to cultivate land, dig water channels, and construct irrigation systems in large-scale agricultural production.

Forestry: used for logging, clearing forest paths, clearing trees, and transporting timber.

Railway construction and maintenance: It is also applied in the excavation of railway lines, filling of ballast beds, construction of bridges and tunnels, and other aspects.
