摘要
电子液位控制系统可以很好地实现对液位的控制,保证系统的平稳运行并提高效率。但是电子液位系统中的关键部件,如液位传感器,依然面临某些问题,例如液位传感器和执行机构的准确性/控制精度以及可维护性问题。本文尝试采用新型液位传感技术——导向雷达液位测试技术配合电动阀作为执行机构,确保工业制冷系统安全运行可靠的同时,提高系统效率、增强系统的可维护性。
The electronic solution for liquid level control can control the liquid level stably and make sure the plant work in a stable mode with high energy efficiency. But the key elements of the control system, such as traditional capacitive level sensor and the op- erating valve, still face some problems. It is very important to keep the sensor controlled valve has high accuracy and with better maintenance. A new liquid level sensor with TDR technology and a robust motor valve is introduced, which will work together to make the refrigeration system running in a safe and energy-saving way with easier service.
