挖土机的工作原理
1. Excavators are heavy construction equipment consisting of a
boom, dipper (or stick), bucket, and cab on a rotating platform
known as the "house".
挖土机是由一根臂、一根铲杆、一个斗和一个驾驶室组成的重型建筑设备，
它们被安装在一个称为"车屋"的旋转平台上。
2. The basic operating principle of an excavator involves using
hydraulic power to drive the mechanical arm and bucket. When the
operator controls the joysticks inside the cab, the hydraulic system
kicks into action, enabling the excavator to perform its various
functions.
挖土机的基本工作原理是使用液压动力来驱动机械臂和斗。当操作员在驾驶
室内控制操纵杆时，液压系统会启动，使挖土机可以执行各种功能。
3. The hydraulic system works by transmitting force through the use
of a pressurized fluid, usually oil. When the operator moves the
control sticks, it regulates the flow of hydraulic fluid to the different
hydraulic cylinders, which then move the various components such
as the arm, bucket, and boom.
液压系统通过使用加压液体(通常是油)来传递力。当操作员移动控制杆时，
它调节液压流体到不同的液压缸，然后移动各种组件，如臂、斗和臂杆。
4. The rotation of the excavator is achieved through the use of
hydraulic motors, which allow the entire upper structure to turn in a
smooth and controlled manner. This enables the operator to
maneuver the machine into the desired position for excavation.
挖掘机的旋转是通过使用液压马达实现的，它使整个上部结构能够平稳、受
控地旋转。这使得操作员可以将机器操纵到所需的挖掘位置。
5. The engine of the excavator provides the power necessary to run
the hydraulic system, as well as all the other systems of the machine.
It is the heart of the excavator, providing the energy needed for all
its functions.
挖掘机的发动机提供了运行液压系统以及机器所有其他系统所需的动力。它
是挖掘机的心脏，为其所有功能提供所需的能量。
6. In conclusion, the work principle of an excavator involves a
complex interplay of hydraulic systems, mechanical components, and
operator control. The combination of these elements allows the
excavator to perform its crucial tasks on construction sites, making it
an indispensable piece of heavy equipment in the industry.
总之，挖土机的工作原理涉及到液压系统、机械部件和操作员控制的复杂相
互作用。这些元素的结合使得挖土机能够在建筑工地上执行其重要任务，使
其成为行业中不可或缺的重型设备之一。
