● Frequently Asked Questions (FAQs)
In modern industrial and mechanical applications, supporting systems play a critical role in ensuring stability, safety, and efficient operation. Two of the most prevalent types of supporting systems are hydraulic supporting systems and electric supporting systems. Each system has its unique mechanisms, advantages, and limitations. This article offers a comprehensive comparison between hydraulic and electric supporting systems, focusing on their performance, maintenance, cost, and suitability for various applications.
A hydraulic supporting system uses pressurized fluid to generate force and motion. The system typically consists of components such as hydraulic cylinders (or props), pumps, valves, fluid reservoirs, and safety devices. The fluid pressure is harnessed to produce high force output, which is essential for heavy-duty support tasks.
- Hydraulic Cylinder (Prop): Contains a live column inside a cylinder body, often equipped with safety valves to regulate pressure and prevent accidents.
- Fluid Reservoir: Stores the hydraulic fluid.
- Pump and Valves: Control the flow and pressure of the fluid.
- Energy-Absorbing Components: Some advanced hydraulic props include energy-absorbing anti-shock members to improve safety and durability.
A typical hydraulic prop structure includes a live column, cylinder, and safety valve, with energy-absorbing features designed to handle shock and overload conditions effectively[2].
- High Force Generation: Hydraulic systems can produce very large forces, making them ideal for heavy lifting, pressing, and supporting applications.
- Power Density: They offer superior power density, meaning more force can be generated in a relatively compact size.
- Shock Load Handling: Hydraulic systems are robust against shock loads and can absorb sudden impacts effectively.
- Durability in Harsh Environments: They are explosion-proof, shock-proof, and spark-proof, suitable for hazardous environments.
- Energy Efficiency: Hydraulic systems tend to be less energy-efficient due to fluid friction, heat generation, and leakage.
- Maintenance Intensive: They require regular maintenance, including fluid changes, leak management, and replacement of worn parts like seals and hoses.
- Complexity and Initial Cost: The complexity of components such as pumps, valves, and reservoirs leads to higher initial investment and installation costs.
- Noise and Environmental Concerns: Hydraulic systems can generate high noise levels and pose environmental risks due to fluid leaks and disposal issues.
Electric supporting systems rely on electric motors and actuators to provide motion and force. These systems use electrical energy to drive motors, which convert it into mechanical force with high precision and control.
- Electric Motor: Converts electrical energy into mechanical motion.
- Controllers and Sensors: Provide precise control over motion, speed, and position.
- Power Supply: Typically requires only electrical power, making installation simpler.
- Precision and Speed: Electric systems offer excellent positioning accuracy and fast response times, ideal for automation and robotics.
- Energy Efficiency: They consume less energy compared to hydraulic systems due to fewer moving parts and no fluid losses.
- Low Maintenance: Electric systems have fewer wear parts and do not require fluid changes, reducing maintenance needs.
- Cleaner Operation: They produce minimal noise and do not involve fluid leaks, making them environmentally friendly.
- Simpler Installation: Electric systems are generally easier and cheaper to install, especially for applications with moderate force requirements.
- Lower Power Density: Electric systems usually cannot match the high force output of hydraulic systems in a compact size.
- Shock Load Sensitivity: Electric actuators can be affected by shock loads, potentially damaging lead screws or bearings.
- Cost of Repairs: While maintenance is low, repairs, especially of controllers or motors, can be expensive.
- Thermal Limits: Electric motors may overheat if operated beyond their duty cycle or in extreme conditions.
| Aspect | Hydraulic Supporting System | Electric Supporting System |
|---|---|---|
| Force Generation | Very high, suitable for heavy-duty applications | Moderate, limited by motor size and design |
| Power Density | High | Lower compared to hydraulic |
| Precision Control | Moderate, slower response times | High precision and fast response |
| Energy Efficiency | Lower, due to fluid friction and leakage | Higher, fewer losses and better energy use |
| Shock Load Handling | Excellent, absorbs shocks well | Limited, sensitive to shock loads |
| Noise Level | High noise due to pumps and fluid flow | Low noise operation |
| Environmental Impact | Potential fluid leaks and disposal concerns | Cleaner, no fluid leakage |
Hydraulic systems excel in applications requiring high force and durability, such as construction machinery, mining supports, and heavy industrial presses. Electric systems are preferred where precision, speed, and energy efficiency are paramount, such as in automation, robotics, and light-to-medium load applications[1][3].
Hydraulic systems demand regular maintenance to maintain performance and safety:
- Fluid Changes: Hydraulic fluid must be replaced periodically to avoid contamination.
- Leak Management: Seals, hoses, and fittings need inspection and repair to prevent leaks.
- Component Wear: Pumps, valves, and cylinders are subject to wear and require scheduled replacement.
- Downtime: Maintenance can cause significant downtime and operational interruptions.
Electric systems are generally more reliable and require less frequent maintenance:
- Minimal Wear Parts: Fewer moving parts reduce wear and tear.
- No Fluid Management: Eliminates fluid contamination and leakage issues.
- Electrical Checks: Periodic inspection of wiring, connections, and controllers is necessary.
- Specialized Repairs: Control system failures may require expert servicing but are less frequent.
Overall, electric systems offer lower maintenance costs and higher reliability, while hydraulic systems require more upkeep but provide robustness in demanding environments[1][3].
| Cost Aspect | Hydraulic Supporting System | Electric Supporting System |
|---|---|---|
| Initial Investment | Higher due to complex components and installation | Generally lower, simpler installation |
| Operational Costs | Higher due to energy inefficiency and maintenance | Lower energy consumption and maintenance costs |
| Repair Costs | Moderate, parts are durable but frequent | Potentially high, especially for electronic parts |
| Lifecycle Cost | Can be cost-effective for heavy-duty, long-term use | Cost-effective for applications with precision and lower force needs |
Hydraulic systems often require a larger upfront investment but are durable for heavy loads. Electric systems save money over time through energy efficiency and reduced maintenance, although some components can be costly to repair or replace[1][5].
- Heavy load and high-force requirements.

Combining hydraulic and electric technologies is becoming popular to leverage the advantages of both systems. Hybrid systems can provide high force with precise control and improved energy efficiency, suitable for complex industrial needs[1].
1. What is the main difference between hydraulic and electric supporting systems?
Hydraulic systems use pressurized fluid to generate force, offering high power density and force. Electric systems use electric motors for precise control and energy efficiency.
2. Which system is more energy-efficient?
Electric supporting systems are generally more energy-efficient due to fewer losses and no fluid friction.
3. Are hydraulic systems more maintenance-intensive?
