Abstract

Recently, SMART positioners have been widely used to control the on-off and control valves. These devices allow you to set an arbitrary user dependence of the valve travel on the control signal. This makes it possible to provide a linear throughput for the entire piping system. This allows the use of smaller type control valves while maintaining the control range. Accordingly, the energy consumption for controlling the shutoff element is reduced; the value of the reinforcement energy efficiency indicator is improved. In that work analytically calculates a user dependency that takes into account the value of pipeline throughput and allows to obtain a linear throughput of the pipeline system in the entire range of control signal change.

Highlights

The introduction of modern automation technologies improves the energy efficiency of pipeline valves and pipeline systems
Resistance coefficient of pipeline system is equal to sum of resistance coefficients of valves and pipelines
The programmable user function should ensure that the relative stroke h depends on the control signal h = f (Uz), which would provide a linear dependence on the flow capacity of the pipeline-valve system: Fс = Fос+КсUz = Fос+ (1 - Fос)∙Uz where F0С is the initial relative capacity of the pipeline system, КС is the proportionality coefficient (by analogy with (1) КС = 1 - F0С)

Summary

Introduction

The introduction of modern automation technologies improves the energy efficiency of pipeline valves and pipeline systems. Automatic control systems make it possible to optimize operation modes of pipeline systems, which leads to significant savings of energy resources [1]. On-off and control valves are used to automatically control the flow of liquid and gaseous process media. Linear and rotary pneumatic actuators are often used to control valve travel. An important area of research in this area is improving the positioning accuracy of pneumatic actuators. To solve this problem, it is necessary to study the dynamic characteristics and search for the optimal structure of the drive [2,3,4]
