Improving the energy efficiency of the pipeline system by ensuring its linear flow characteristic

摘要

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.
