Wheel excavator is perfectly designed for a wide range of worksites: excavation, mining, loading, leveling, trenching, crushing,
An excavator, also known as a backhoe, is a type of heavy machinery and equipment used for earthworks. It is mainly used for digging, transporting and loading soil, ore and other materials.
The working principle of an excavator can be divided into the following aspects: hydraulic system, power system, working device and control system.
1. Hydraulic system
The hydraulic system of the excavator is the core part of its work. It consists of hydraulic pumps, hydraulic cylinders, hydraulic motors and hydraulic pipelines.
Hydraulic pump through the liquid pressure into mechanical energy, to provide power to the other components of the hydraulic system.
The hydraulic pump transmits the liquid pressure to the hydraulic cylinder and hydraulic motor to produce thrust and rotational force to achieve the work of digging and loading.
2. Power system
The power system of an excavator is usually driven by an internal combustion engine. The internal combustion engine generates energy by burning fuel to drive the hydraulic pump and other mechanical parts.
The power of the internal combustion engine determines the working capacity and efficiency of the excavator. Currently, there are two common types of power systems: diesel engines and electric motors.
3.Working device
The working equipment of excavator mainly includes digging arm, bucket and rotary platform. The digging arm is a part used to control the digging depth and height, which can be retracted and rotated
It can be retracted and rotated to adapt to different working conditions. The bucket is used to dig and load soil and other materials. The slewing platform allows the excavator to rotate within a range to facilitate positioning and manoeuvring.
4. control system
The control system of the excavator is used to control the movement and work of the excavator. It consists of operating levers, control valves and sensors. The operating lever converts the operator's operation into the control signal of the hydraulic system through the mechanical transmission device, so as to realise the movement and work of the excavator.
The control valve controls the working pressure and flow rate of the hydraulic system according to the signal from the operating lever. Sensors are used to detect the working status of the excavator and environmental parameters, so as to adjust and protect the work of the excavator in time.
Summary:
The working principle of the excavator is based on the synergy of the hydraulic system, power system, working device and control system.
The hydraulic system provides power, the power system drives the hydraulic system, the working device completes the digging and loading work, and the control system controls the movement and work of the excavator. These components cooperate with each other, so that the excavator can efficiently and accurately complete a variety of earthmoving tasks.
These components work together to enable the excavator to efficiently and accurately complete a variety of earthmoving tasks.
