摘要
本文从实际运用角度出发,设计了一套组合式微小流量计量与控制系统。该系统采用组合式管排,仅使用单调节阀及单流量计,通过电磁阀切换不同管路,巧妙运用恒差压阀稳定调节阀前后压差,实现了流量从0.009m3/h至2.700m3/h的宽量程计量,现场使用效果良好。本系统采用组态软件MCGS及Visual Basic混和编程,人机界面友好,系统稳定,在微小流量计量与控制中具有一定的推广应用价值。
A small flow measurement and control system for practical application has been studied in this paper. This system adopts combined pipes, using only one control valve and one flowmeter. The system changes the pipes through electromagnetic valve, and adjusts the expected pressure by stabilizing the constant pressure valve. And then, it implements the wide-range measurement from 0.009m^3/h to 2.700m^3/h and there is a good result in real-time. The system is programmed by configuration software MCGS and Visual Basic with friendly interface and steady performance, so it can be widely used at small flow measurement field.
