Electronic flow regulators and electronic flow control valves are devices that use an electronic signal to regulate the velocity of the fluid (liquid or gas). The digital water flow controller is used to manage the rate of the water phase. In contrast, the electronic air recirculation control valve is often used to adjust the speed of rotors and air motors. A sealed loop control system comprising an electronic pneumatic flow control valve and a digital flow meter provides a digital readout of the liquid or gas flow rate, allowing them to anticipate the exact amount of flow.
What Is The Electronic Flow Control Valve’s Operating Principle?
Electronic pneumatic flow control valve come in a variety of configurations. This section will discuss the kind that employs a linear servo motors actuator and a proportional needle valve.
What Is The Purpose Of A Stepper Motor?
Stepper motors are brushless direct current motors that revolve in predetermined steps. The controller supplies electric current through electromagnets organized in a spiral as part of the generator component (the stationary portion of the motor). The stepper motor’s technical design minimizes engineering and manufacturing delays, often an issue with other motors. The precision, resolution, and sensitivity of a stepper motor give it a significant edge over other types of motors. Stepper motors are often used in mechanization, motion control, and 3D printing.
What Is A Linear Actuator With A Stepper Motor?
A stepper motor may be equipped with a threaded shaft that can push or pull a nut (needle valve) placed on it, axially moving it. The thread pitch determines the accuracy of the flow valves; this is also determined by the step angle of the stepper motor employed (full, half, quarter, etc.). As is the case with the majority of linear motion technologies, a stepper linear actuator is susceptible to backlash, which is specified as the most significant distance or angle through which any mechanical component. They may be pushed in one direction without providing resistive force or movement to the following part, when the direction of movement is altered, than separation between strands results in a dead zone. When switching direction, the linear actuator will remain stationary until the clearance between the threads is gone (the threads make contact again).
What Is an Electronic Flow Control Valve Controlled By A Stepper Motor?
In this instance, a stepper motor is utilized to regulate the distance between the gauge and the valve seat. The sharpness, accuracy, and consistency of a parker flow control valve are all governed by the precision with which the needles are set. Other factors, such as velocity, torque, and operating pressure, are governed mainly by the stepper motor’s properties.
What Factors Should You Consider While Selecting An Electronic Flow Control Valve?
It is critical to determine if the media you employed falls within the operational valve’s flow range. Because each medium has a varied density, the flow valves will vary from the statutory flow range. You must determine if the medium employed is appropriate with the wet substance and whether the body must also be made of a particular material. Another caution is that operating pressure is not always critical if flow control is required.
