Energy efficiency and control advantages of electric pneumatic actuator:
What is the difference between electric and pneumatic actuators?
A table showing the differences between electric and pneumatic actuators.
| Electric Actuator | Pneumatic Actuator | |
| Power source | Electrical power | Compressed air |
| Working principle | Motor driven actuator | Air pressure energy is converted into mechanical energy |
| Control accuracy | High, easy to match with electric adjustment instrument | Relatively low, dependent on air pressure regulation |
| Response speed | Fast, the motor starts and stops quickly | Also very fast, but affected by air pressure regulation |
| Driving torque | Moderate, depending on motor power | Large, suitable for large diameter, high pressure valves |
| Adaptability | Widely used, but may not be applicable in places with high explosion-proof requirements | Good, especially in harsh environments |
| Energy saving and environmental protection | Requires electrical energy, but modern electric actuators are energy efficient | No electricity consumption, energy saving and environmental protection |
| Maintenance costs | High, complex structure | Relatively low, simple structure |
Electric control optimizes energy efficiency and performance of pneumatic actuators.
- Intelligent control: By installing sensors and controllers, precise control of pneumatic actuators can be achieved. For example, the air pressure can be adjusted according to the actual load conditions to avoid energy waste caused by excessive air pressure. At the same time, by utilizing the feedback function of the electric control system, the operating status of the actuator can be monitored in real time, and adjustments and optimizations can be made in a timely manner.
- Energy-saving mode: Under partial load conditions, the use of electric control can put the pneumatic actuator into energy-saving mode. For example, lowering the air pressure or reducing the air flow, thereby reducing energy consumption.
- Integrated control: Integrate electric and pneumatic actuators into one system to achieve collaborative work. Precise control of pneumatic actuators by electric control units can improve the overall performance and energy efficiency of the system.
Safety and Compliance of electric pneumatic actuator:
1. Safety standards and regulations for electric pneumatic actuator.
- Chinese standards: In China, the design and operation of electric pneumatic actuator must comply with national standards, such as “Actuators for Industrial Automation Instrumentation” (GB/T 17213). In addition, it is necessary to meet the relevant production safety laws and standards must be met, such as “the Production Safety Law”, “the Special Equipment Safety Law”, etc.
- International standards: Internationally, electric pneumatic actuator are usually required to comply with international standards, such as ISO 5211 (connection flange dimensions for valve drive devices), IEC 60079 (electrical equipment for explosive atmospheres), etc.
2. Practical advice for ensuring device security and compliance.
(1) Design stage:
• Designed in strict accordance with standards and regulations to ensure that the structural strength, sealing performance, explosion-proof performance, etc. of the electric pneumatic actuator meet the requirements.
• Conduct risk assessments to identify potential safety risks and take appropriate measures to prevent them. For example, set up overload protection, limit devices, emergency stop buttons, etc.
• Select materials and components that meet standards to ensure the quality and reliability of electric pneumatic actuator.
(2) Manufacturing stage:
