The excavator engine is one of the core components of the excavator. Its main function is to provide power to drive the operation of the entire excavator. It mainly provides power, then rotates the hydraulic pump and hydraulic motor, and finally drives the wheel transmission system and hydraulic fans and other ancillary equipment.
The excavator hydraulic system generally consists of hydraulic pumps, hydraulic cylinders, hydraulic valves and other components. The hydraulic pump is the heart of the excavator hydraulic system. The hydraulic pump is an energy conversion device. Its function is to move the fluid and convert mechanical energy into fluid energy.
The role of the excavation distribution valve in the excavator is to control the flow distribution of the hydraulic system to achieve coordination of various hydraulic actuators, flow balance, energy saving and consumption reduction.
The excavator cab is the control center of the excavator and its function is very important. The excavator cab usually controls and operates functions, including starting and stopping the machine, driving and steering, throttle and brakes.
The functions of the chassis system mainly include the following three parts: 1. Support the upper weight of the entire excavator 2. The power source and actuator for walking and steering 3. Support the reaction force of the working equipment during excavation.
