Characteristics of the Yadeke control system
The Yadeke control system is suitable for applications with low output power and dynamic The performance requirements are not high, the working environment is relatively harsh at high or low temperatures, and there are high requirements for fire protection. The pneumatic control system has the following characteristics:
1. Due to the compressibility of gas, the response speed of the pneumatic system is low. When the working pressure and load are the same, the response speed of the hydraulic system is about 50 times that of the pneumatic system. times. At the same time, the stiffness of the hydraulic system is approximately 400 times that of the equivalent pneumatic system.
2. Since the pneumatic system does not have a pump control system, but only a valve control system, the efficiency of the valve control system is low. The overall efficiency of the valve-controlled hydraulic system and pneumatic servo system is about 60% and 30% respectively.
3. Since the viscosity of the gas is very small, the lubrication performance is not good. Under the same machining accuracy, the air leakage of pneumatic components and the dry friction between the moving pairs are relatively large, and the load is prone to crawling.
4. Simple energy generation and energy storage.
5. Small size and light weight.
6. Temperature changes have little impact on the working performance of pneumatic proportions and servo mechanisms.
7. The pneumatic system is relatively safe, less prone to fire, and will not cause environmental pollution.
