In-Depth Analysis of the Excavator Hydraulic System
● The hydraulic system plays a crucial role in an excavator as it is the core power source for driving the machine's work attachments, such as the hydraulic arm, bucket, and swing platform. The hydraulic system transmits energy through hydraulic fluid, utilizing the incompressibility of the liquid to convert mechanical energy into power that drives various operational actions. The stability and efficiency of the hydraulic system directly affect the excavator's performance, working efficiency, and service life. Below is a detailed analysis of the excavator's hydraulic system.

1 -
Hydraulic Pump
The hydraulic pump is the power source of the hydraulic system, converting the mechanical energy from the engine into hydraulic energy by providing a flow of hydraulic fluid. Hydraulic pumps are typically classified into gear pumps, piston pumps, and vane pumps. The hydraulic pumps provided by SPARKLING are made from efficient and durable materials, ensuring long-term stable hydraulic flow output.
2 -
Hydraulic Motor
The hydraulic motor converts hydraulic fluid flow into rotary or linear motion, used in excavators to drive components such as tracks and swing platforms. SPARKLING's hydraulic motors are characterized by high torque and high efficiency, suitable for various load-bearing working environments.
3 -
Hydraulic Valves
Hydraulic valves are used to control the direction, flow, and pressure of hydraulic fluid, ensuring precise operation of each work attachment. Common hydraulic valves include main control valves, circuit valves, proportional valves, and directional control valves. SPARKLING's hydraulic valves are manufactured with high precision to ensure stable operation, rapid response, and improved work efficiency.
4 -
Oil Tank and Hydraulic Fluid
The oil tank stores hydraulic fluid, which circulates through the system to transmit power and cool the system. SPARKLING provides high-quality hydraulic fluid and tank designs to ensure that the fluid remains clean, flows smoothly, and prevents air from entering the system, avoiding leaks or oxidation.
5 -
Hydraulic Hoses and Seals
Hydraulic hoses and seals are indispensable components of the hydraulic system, responsible for transmitting hydraulic fluid and ensuring system integrity. SPARKLING’s hydraulic hoses and seals are made from high-pressure-resistant and corrosion-resistant materials, ensuring the system operates efficiently and steadily, preventing leaks and damage.
Working Principles of the Hydraulic System
The hydraulic system uses the incompressibility of the liquid to transmit force by pushing hydraulic fluid to various components in the system, generating thrust or rotational force to drive work attachments. The process is as follows:
01
Hydraulic Pump Provides Flow
The engine drives the hydraulic pump, which draws in and compresses hydraulic oil, providing the required flow to the hydraulic system. The flow rate and pressure of the hydraulic pump are key factors affecting the efficiency of the entire hydraulic system.
02
Hydraulic Valves Control Oil Flow
Hydraulic valves regulate the direction and pressure of hydraulic fluid based on operational needs, precisely controlling the flow of hydraulic oil to various work attachments. Proportional valves and directional valves are used to finely adjust the system, ensuring stable operation under different working conditions.
03
Hydraulic Motors and Work Attachments
Hydraulic motors convert the hydraulic oil's energy into power, driving components like tracks and the swing platform to perform tasks. Hydraulic cylinders generate linear force from hydraulic oil pressure, driving work attachments such as the hydraulic arm and bucket.
Compatibility and Adaptability of the Hydraulic System
Multi-Brand Compatibility
The hydraulic components provided by SPARKLING are compatible with various excavator brands and models, such as Komatsu, Caterpillar, Hitachi, Volvo, and more. Whether for newer or older models, our hydraulic parts are perfectly matched to ensure efficient operation.
