Working principle of excavator

The working principle of excavators can be divided into two aspects, namely mechanical drive and hydraulic control. Mechanical drive is driven by the engine to drive the transmission chain, drive the mechanical arm, bucket rod and bucket to complete the excavation and loading operations; Hydraulic control is to drive the oil circuit through the hydraulic pump to control the movement mode and action of the mechanical arm and bucket, making the operation of the excavator more accurate and efficient.

In terms of mechanical drive, the core component of excavator work is hydraulic engine. The hydraulic engine is the source of energy to drive the excavator, and when it starts, it drives the transmission chain, which drives the action of the robot arm, bucket rod and bucket. At the same time, the hydraulic engine can also adjust the power output and working speed of the excavator by raising and reducing the speed, to meet the engineering needs of different occasions.

In terms of hydraulic control, the hydraulic system of the excavator plays a crucial role. The hydraulic system is composed of hydraulic pump, hydraulic cylinder, oil tank, hydraulic pipeline and other components. The hydraulic pump is responsible for providing the pressure source for the hydraulic system and transferring the pressure to the hydraulic cylinder and other hydraulic components. The hydraulic cylinder is to accept the pressure provided by the hydraulic pump to promote the mechanical arm, bucket rod and bucket. At the same time, the hydraulic system of the excavator also has the functions of reverse pressure control and safety protection, which ensures the stability and safety of the excavator during the operation.

In summary, the working principle of the excavator includes two aspects: mechanical drive and hydraulic control, which are inseparable. The importance of excavators in the engineering field is self-evident, I believe that through continuous technological innovation, the performance and efficiency of excavators will continue to improve, and bring more convenience to people's production and life.
