Our goal: to be a high-quality manufacturer of industrial control valves, gaining unanimous recognition from new and old customers
Our mission: To fully utilize the effectiveness of industrial control valves to achieve better results
As a very important equipment in the automatic control system, the control accuracy of electric actuators is very important regardless of the type or domestic import of electric actuators. As a professional manufacturer of electric actuators, Heli has compiled the following data to enable people to perform different operations according to different situations, in order to solve the problem of low control accuracy of electric actuators. The synthetic force has been debugged many times, and the solutions mentioned above can be well applied in practice.
Improper selection of electric actuators, control valve vibration, brake failure of electric actuators, low output hysteresis, and the sensitivity of servo amplifiers can lead to low control accuracy of electric actuators. When encountering the above problems, how to improve the control accuracy of electric actuators.
1。 Due to low control accuracy and selection issues, the selection of electric actuators requires organizational selection before selecting key points. When we should comprehensively consider the entire load of electric actuators, electric actuators are used to control greater fluid fluctuations. Generally, electric actuators with large output force are selected. Regularly clean the regulating valve, maintain the flexible valve shaft, and ensure the control accuracy of the electric actuator.
2。 Adjust the valve vibration. This is one of the common faults of electric actuators. Look for the vibration source. If the vibration is caused by external vibration, then directly remove the electric actuator from the vibration. If the vibration is caused by internal reasons, what we need to do is minimize the resistance of the control valve. If the regulating capacity of the control valve allows, we can add a bypass pipe. This reduces vibrations caused by the flow of media.
