Hydraulic Power System Complete Introduction
1. Basic Product Overview
The Hydraulic Power System, commonly referred to as a hydraulic power unit (hydraulic station) in the industry, is an integrated standalone hydraulic oil supply assembly integrating an electric motor, hydraulic pump, oil tank, control valve bank, monitoring gauges and auxiliary accessories. It delivers pressurized hydraulic oil at stable pressure to drive actuators like hydraulic cylinders and motors, widely applicable to industrial automation, engineering machinery, metallurgy, warehousing lifting equipment and other scenarios. The multiple GEYAO models shown in the pictures all fall into this product category.
Core Components (Matching Parts in the Actual Photos)
1. Power Drive Module: Three-phase asynchronous motor + hydraulic pump (gear pump / piston pump), converting electric energy into pressure energy of hydraulic oil
2. Oil Storage Module: Carbon/stainless steel oil tank for storing hydraulic oil, heat dissipation and impurity sedimentation, fitted with a liquid level gauge for direct oil level observation
3. Pressure Regulation & Control Module: Relief valves, solenoid directional valves, cartridge valves, one-way throttle valves, etc., to control circuit on-off, pressure and flow rate
4. Safety Monitoring Module: Pressure gauges for real-time pressure detection, oil temperature & liquid level rulers, pressure sensors, safety relief valves
5. Auxiliary Expansion Module: Accumulators for pressure stabilization and holding, air coolers for temperature control, movable casters, lifting lugs, electric control cabinets, oil filters
2. Main Classifications (Matching the 6 Models in Pictures)
2.1 Compact Basic Models (Picture 1 & 2)
- Structure: Vertical motor + simple valve block + small-capacity oil tank with compact layout
- Application: Simple single-station fixture clamping, small lifting platforms and basic jigs
- Features: Low cost, small footprint, operating pressure ranging from 3–21MPa conventionally
2.2 Mid-size Integrated Models (Picture 5)
- Structure: Horizontal motor + multi-circuit solenoid directional valve group for independent control of multiple actuators
- Application: Multi-station automatic assembly lines, dual-cylinder synchronous mechanisms
2.3 High-end Pressure-stabilized Models (Picture 3 & 4)
- Extra parts: Large-capacity accumulators, multi-stage gauge panels, precision oil filters, standalone electric control cabinets
- Application: Metallurgical equipment and machine tool jigs requiring instantaneous large flow, pressure holding during power loss and minimal pressure fluctuation
2.4 Mobile Heat-dissipation Models (Picture 6)
- Extra parts: Swivel casters for mobility, dedicated air cooling assembly
- Application: Movable workshop workstations, temporary outdoor hydraulic operations and scenarios with long high-load continuous running
3. Working Principle
1. The motor drives the hydraulic pump to draw oil from the tank and deliver pressurized hydraulic oil;
2. Relief valves set the maximum safe system pressure, diverting excess oil back to the tank;
3. Directional valves switch oil flow direction to control cylinder extension/retraction and motor forward/reverse rotation;
4. Accumulators buffer pressure spikes, coolers stabilize oil temperature, and gauges track operating parameters to achieve steady oil supply in a closed loop.
4. Key Performance Parameters (Universal Selection Standards)
Parameter Common Range Note
Rated Working Pressure 3~35MPa 3–7MPa for low-pressure jigs, up to 35MPa for heavy-duty metallurgy equipment
Output Flow 1~100L/min Determined by pump displacement and motor speed, matching actuator moving speed
Motor Power 0.75~37kW 0.75–3kW for compact units, above 15kW for heavy-duty stations
Tank Volume 20~1000L Selected according to continuous operation duration and heat dissipation needs
Control Mode Manual / Solenoid / PLC Automatic Manual valves for simple tasks, PLC-linked electric cabinets for automated production lines
5. Core Advantages
1. High Integration: Delivered as a complete set for plug-and-play use, eliminating scattered part procurement and complex on-site assembly & commissioning
2. Flexible Customization: Compatible with stacked directional valves, hydraulic locks, cooling and pressure-holding modules to realize multi-circuit synchronization, pressure retention and speed regulation
3. Reliable Safety: Built-in overpressure relief, liquid level & oil temperature monitoring for automatic overload pressure release, stable for long continuous operation
4. Easy Maintenance: Modular layout enables quick replacement of filter elements, seals and valve parts
6. Typical Application Scenarios
Clamping jigs for industrial machine tools, lifting platforms & stereo garages, auxiliary mechanisms for compact construction machinery, supporting cylinders for metallurgical equipment, warehouse stackers, hydraulic stations on automatic production lines, small hydraulic units for marine deck machinery.
