How’s electric actuator working in thermal power plant
In the thermal power plant, the operator sends the on-off signal or analog signal to the DCS system through the operating computer, and then DCS system transmits the signals to the electric actuator through cables, the electric actuator acts according to the corresponding signal to make the valve to reach full close, full open or a middle position as requested. Therefore, electric actuator has a very wide range of applications in thermal power plants, which is an indispensable part of automation control in thermal power plant.
Due to the extremely bad environment of some working condition in thermal power plant, such as high temperature, vibration, dust and narrow space, which is not conducive to maintenance ,so the requirements for electric actuator installation are extremely strict. How to ensure that the electric actuatorat the current station will not maloperate,won’t refuse to move,keep stable signal transmission, no failure for a long working time, etc. is the most important thing related to the safe and stable operation of the whole unit.
