Advantages of Hydraulic System
Compact Structure
The compact and integrated design reduces installation footprint and simplifies system layout. By integrating multiple components into a unified configuration, the system minimizes piping complexity and reduces potential leakage points.
Stable Pressure
Engineered for stable pressure output throughout the operating range. This consistent pressure control ensures smooth operation of connected machinery and reduces hydraulic shock that could damage system components.
Energy Efficiency
Optimized energy consumption through advanced servo control and intelligent linkage technology. The system delivers hydraulic power precisely where and when it is needed, reducing unnecessary energy waste compared to conventional hydraulic systems.
Easy Maintenance
The modular design and simplified layout facilitate routine maintenance and troubleshooting. Clear component accessibility and standardized interfaces reduce maintenance time and associated labor costs.
Servo Control Precision
High-precision servo control with fast response and closed-loop feedback. This enables precise motion control and pressure regulation, meeting the demanding requirements of injection molding, die casting, and precision manufacturing applications.
Extreme Condition Adaptability
Designed to operate reliably under extreme working conditions, including high pressure, large flow, and harsh environments. The robust construction and contamination-resistant design ensure consistent performance in demanding industrial settings.
Construction Machinery
Excavators, cranes, and loaders require high-pressure large-flow hydraulic power for lifting, digging, and rotating motions. A hydraulic system with robust construction and servo control delivers reliable power transmission and precise motion control under harsh operating conditions.
Steel Mills
Continuous casting and rolling mills demand stable pressure and high-force control for non-stop production. A proportional or servo hydraulic system provides consistent pressure output, closed-loop feedback, and energy-efficient operation for heavy-duty metal forming processes.
Waste Processing & Recycling
Baling presses and compactors in waste processing facilities operate under heavy loads and dusty environments. Hydraulic systems with contamination-resistant design and stable pressure control ensure reliable performance and easy maintenance in demanding conditions.
New Energy Manufacturing
Wind turbine assembly, solar panel production, and battery manufacturing lines require precise and energy-efficient hydraulic control. Servo hydraulic systems with intelligent linkage deliver accurate pressure and position control while reducing unnecessary energy consumption.
Specialized Industrial Equipment
Non-standard hydraulic presses, forming machines, and custom automated systems require tailored force and motion control. A hydraulic system with multi-cylinder synchronization and digital regulation adapts to specific speed, pressure, and positioning requirements across diverse applications.

Installation Steps for Hydraulic System
Preparing the Installation Site
Begin by inspecting the installation site. Ensure the area is clean, level, and capable of supporting the total weight of the hydraulic system, including the reservoir, pump unit, and connected piping. Verify that sufficient space is available for routine maintenance, oil filling, and heat dissipation.
Positioning and Securing the System
Move the hydraulic system into place using appropriate lifting equipment such as a forklift or overhead crane. Align the unit with the foundation bolts and secure it firmly. Check that the system is level to prevent uneven loading and ensure proper oil return to the reservoir.
Connecting Hydraulic Lines and Electrical Supply
Connect the pressure, return, and drain lines to the designated ports. Ensure all pipes and fittings are thoroughly cleaned before installation to prevent contamination of the hydraulic fluid. Then connect the main power supply, control signals, sensors, and grounding conductors according to the electrical schematic.
Filling, Bleeding and Testing
Fill the reservoir with clean, filtered hydraulic fluid of the recommended grade. Run the pump briefly to bleed air from the system, opening bleed points on cylinders and high points in the piping as needed. Start the pump in jog mode to verify correct motor rotation, gradually increase system pressure, inspect all connections for leaks, and calibrate the proportional or servo control parameters to match the application requirements.
