Multi Rotary Valve Electric Actuator The Use Of More Secure, The Organization Is Also More Simple
Sep 28, 2017

Modern production control system mostly use Multi Rotary Valve Electric Actuator mechanism, which is relatively safe with the traditional valve control device, the organization is also more simple, more life. Valve electric head can be divided into two parts, the upper part of the electric control part of the lower part of the main part of the valve, electric actuator applications for a wide range of adaptability to a variety of conditions, so by the majority of users love, Has been used as a safety intelligent valve control device.

When the electric actuator in the practical application of the operation of our users to rationally spent three stages. The first is the beginning of the run is the run-in period. Most of the failures occurred during the selection, design or installation and the environment caused by. For example, when the torque is too small may directly affect the Multi Rotary Valve Electric Actuator adjustment speed. If the installation of the power lines and signal lines will be mixed together, it will cause a large signal interference, the stability of the motor operation have an impact. Encountered these problems must be promptly discovered and dealt with, so as to avoid unnecessary losses. When the valve electric head into the middle of the operation, the overall performance of the control mechanism has also entered the adaptation period most of the performance was more stable, there will be individual minor problems, the user can only do the appropriate maintenance. When the Multi Rotary Valve Electric Actuator into the late operation, most of the aging of the components of the existence of the problem, in particular, the various parts of the transmission parts serious, resulting in reduced stability of the control operation, or intelligent positioning module positioning accuracy. For these questions the user should find out why the repair or replacement parts are better resolved.

Electric actuators have become the mainstream products on the mechanical market. Automatic valve is the most can not be missing is the electric actuator, when the work can effectively save energy consumption. Advantages of the performance of electric actuators determines the effectiveness of the use of time to improve efficiency and energy efficiency. The type of motor is more numerous, in the market angular electric head and so on the different nature of the electric head. The most commonly used electric head is the most traditional electric head. In the more advanced Rotork electric actuators compared to traditional electric actuators are much less, but does not affect the traditional electric actuator market.

Conventional electric actuators also have advantages. In the energy on the access is more convenient, just plug in the power can work. The signal is transmitted at a faster speed and can travel far distances. In the long-distance transmission control will not be affected in the control of the time still has a strong precision, not because the distance is too far can not control. The installation of the visual wiring process is relatively simple, not cumbersome. In case of failure can quickly check out the problem of failure, when the line can quickly replace the problem line into a new line. Maintenance is relatively simple, without the need to consume a lot of maintenance costs.

The disadvantage of the existence of electric actuators is the structure is more complex, it is easy to fail. As the structure is more complex, the need for a strong professional knowledge and technical maintenance personnel. Failure in the electric actuator is able to quickly solve the fault, professional knowledge and technical maintenance personnel in the maintenance of time will consume a lot of time. Reduced working time and reduced efficiency.

The most widely defined definition for an actuator is a drive that provides linear or rotary motion that utilizes some kind of drive energy and operates under some control signal. The actuator uses liquid, gas, electricity, or other energy sources and converts it into a drive by means of a motor, cylinder, or other device.

The basic types are part-turn (Part-Turn), multi-turn (Multi-Turn) and straight trip (Linear) three drive.

The basic actuator is used to drive the valve to a fully open or fully closed position. The actuator for the control valve can precisely bring the valve to any position. Although most of the actuators are used to switch valves, today's actuators are designed to go beyond simple switching functions, including position sensing devices, torque sensing devices, electrode protection devices, logic control devices, digital communication modules And PID control module, etc., and these devices are all installed in a compact shell.

Because more and more plants are equipped with automated control, manual operation is replaced by mechanical or automated equipment, requiring the actuator to act as an interface between the control system and the valve mechanical movement, requiring the actuator to enhance operational safety performance and Environmental protection performance. In some dangerous situations, the automated actuator device can reduce the damage of personnel. Some special valves require emergency opening or closing in exceptional circumstances, and the valve actuator can prevent further diffusion of hazards while minimizing plant losses. For some high-pressure large-diameter valves, the required actuator output torque is very large, then the required actuator must improve the mechanical efficiency and the use of high-output motor, so as to smooth operation of large diameter valves. For some small torque of the valve, small electric valve is also applied, compared to the ordinary type with light weight, compact structure, complete functions and so on.

In order to successfully automate the process, the most important thing is to ensure that the valve itself can meet the process and the special requirements of the medium within the pipeline. Usually the production process and process media can determine the type of valve, the type of spool and trim and valve structure and materials.
