Overview
- Effeciently controls the inlet valve and blow-off valve when the compressor starts and stops.
- During steady operation, controls the inlet valve so that the amount of discharged compressed air becomes constant (flow control)
- Surging: Load decreases, the amount of discharge flow and pressure drop, and a limit is exceeded, possibly destroying the compressor.
In such cases, the YS1700 Single-loop Controller switches smoothly and automatically between flow control and pressure control to prevent surging.
* A compressor is an important device in every kind of factory that is used to compress air, oxygen, hydrogen, and other source gases and process gases.

- Selector Control (YS Specific Algorithm)
Allows for automatic switching between two differing control factors, flow volume and pressure. - High Speed Control Interval (50 msec)
Keeps up with fast process changes, enables smooth switching control. - User Programming
Enables start-stop sequences and can be customized in various ways for compressors.

上游
上游行业涵盖海上和陆上作业,包括井口自动化、分馏、完井和分离等环节,旨在开采并初步处理地下或水下原油与天然气。
石油被采至地表后,必须在运输前进行分离。通常在初级和二级分离阶段,通过三相分离将气流、水流和油流分开。气体输送需要管道,并可在上游阶段加入分馏处理。液体则存入储罐或通过管道输送至加工环节,此过程需准确的液位测量。
