Excavator is an indispensable heavy machinery equipment in engineering construction. It is mainly composed of the following parts.
First is the power system. Among them, the engine is usually a diesel engine, which provides power source for the entire excavator. The performance of the engine directly affects the working efficiency and reliability of the excavator. The high-power engine can give the excavator the ability to operate smoothly under complex working conditions. The hydraulic pump converts the mechanical energy of the engine into hydraulic energy, and through the engine drive, the pressurized hydraulic oil is delivered to the hydraulic system to provide power for each action of the excavator. Its performance and quality play a key role in the working efficiency and stability of the excavator.
The working device is also an important component. As one of the main working parts, the boom can be driven up and down by the hydraulic system to achieve actions such as excavation and lifting. The length and strength of the boom determine the excavation depth and working range of the excavator. The boom is connected to the front end of the boom, and can be extended and swung under the drive of the hydraulic system to perform operations such as excavation and loading. The length and strength of the boom also affect the working range and excavation capacity of the excavator. The bucket is an excavation tool that can be opened and closed and rotated by the hydraulic system to complete excavation, loading and unloading. Its shape and capacity vary depending on work requirements.
In terms of the walking device, the crawler consists of track shoes, track pins, track wheels, etc., and is the walking part of the excavator. The crawler supports the weight of the excavator and provides traction, allowing the excavator to travel on various terrains. The width and length of the crawler affect the stability and passability of the excavator. The travel motor is a key component that drives the crawler to travel. The hydraulic system converts hydraulic energy into mechanical energy to rotate the crawler. Its performance and quality directly determine the travel speed and traction of the excavator.
The slewing device includes a slewing platform and a slewing motor. The slewing platform is the upper structure of the excavator. It can be driven by the slewing device to achieve 360-degree rotation. The engine, cab, working device and other components are installed on it. The slewing motor is driven by the hydraulic system to convert hydraulic energy into mechanical energy to rotate the slewing platform. Its performance and quality are crucial to the slewing speed and stability of the excavator.
There are operating consoles, seats and seat belts in the cab. The operating console is where the driver operates the excavator, and it is equipped with various operating handles, buttons and instruments. The driver controls the various movements of the excavator through the operating console to realize functions such as digging, loading and walking. The seat and seat belt provide comfort and safety for the driver. The seat design conforms to the principles of ergonomics, and the height, angle and position can be adjusted to meet the needs of different drivers. The seat belt protects the driver's safety in the event of an accident.
The hydraulic system includes a hydraulic oil tank, hydraulic pipelines and control valves. The hydraulic oil tank stores hydraulic oil and provides sufficient hydraulic oil for the hydraulic system. Its capacity and quality affect the working efficiency and stability of the hydraulic system. The hydraulic pipeline connects the various components of the hydraulic system and transports hydraulic oil to various actuators to realize various movements of the excavator. Its quality and sealing are crucial to the working efficiency and safety of the hydraulic system. The control valve controls the flow and pressure of the hydraulic system. The flow direction and pressure of the hydraulic oil are controlled by the driver to realize various movements of the excavator. Its performance and quality directly affect the working efficiency and operating accuracy of the excavator.
For second-hand dealers, it is of great significance to understand the components of the excavator. When acquiring a used excavator, it is necessary to conduct a comprehensive inspection and evaluation of each component to determine the performance and value of the equipment. When selling a used excavator, you can introduce the components and functions of the excavator to customers to help them better understand the equipment and make an informed purchasing decision.
In short, an excavator consists of many parts, each of which plays an important role. Knowing the components of an excavator is essential to properly operate, maintain, and repair the excavator. At the same time, second-hand dealers can also provide better service and support to customers by understanding the components of the excavator.
