Intelligent electric actuators are powerful

At present, most of the electric actuators  in power station projects use intelligent type, which is powerful and can be combined with conventional instruments to form a simple control system. In the system with DCS, due to the powerful function of the system, the function of theElectric Actuatoritself is also made
It is not fully utilized, so in the automatic control system of the power station, the selection of actuator equipment must be taken seriously to meet the functional requirements. At present, there are many types ofElectric Actuators used in power stations, and their functions are also quite different
Systems with simpler logic are too extravagant and have many functions that are not used [1]. This is mainly due to the fact that designers pay too much attention to the parameters of the valve and ignore or do not clarify the relevant requirements for electric actuators, which is in the market economy. The drawbacks arising from the system.This kind of only paying attention to the parameters of the electric actuator will inevitably make the electric actuator not give full play to the best performance, and it will also bring unnecessary trouble in the process of installation, commissioning and use, and even cause serious consequences to production. needle in view of this problem, the key points that should be considered in the selection of electric actuators in power stations are briefly introduced, and the functional selection and related advantages and disadvantages of current intelligent electric actuators are briefly introduced. 1. Select the type of electric device for the valve, electric device of the power station, and electric actuator in different industries, it is called a valve electric device in the industrial pipeline valve industry, and an electric actuator in the instrument industry [2].
It is commonly referred to as electric actuators. In general, the basis for the correct selection of electric actuators is as follows: 1.1 According to the output type a. Linear stroke (linear motion) is suitable for single-seatControl Valves, double-seatControl Valves, etc. The movement of the output shaft of the electric device is a straight line sporty, not turning. b. Quarter-turn electric device (rotation angle actuatormanufacturer, the device type, the advantages and disadvantages
Integrated, automatic phase sequence adjustment full English menu, the initial debugging is more difficult intelligent, English LCD display, no need to open the cover to set parameters.
