Control Mechanism Analysis in Fluid Drive

In order to improve the security and reliability of industrial control system and realize the automatic detect and control of the system, this article invents and conducts whole scheme design of a multifunctional intelligentized solenoid valve detecting system. The authors have analyzed the conditions of resonance of main test pipeline and its pressure transmission characteristics in frequency domain by impedance analysis. They conduct simulation study to the frequency characteristics of pressure radio of the main test line, by adopting approximation method of fluid pipeline frequency-domain model to make reasonable physical design to the elements like geometric dimensioning and the length of fluid pipeline.
