Analysis of Pipeline Dynamic Flow Signal Coupling in Hydraulic System

The dynamic measurement of the high pressure side flow in hydraulic system is still one of the important and difficult problems in hydraulic test technique. In order to solve the dynamic coupling mechanism between main and bypass oil-way fluid flow signals in the bypass flow measurement method, hydraulic system software was used to analysis the problem in this paper, the dynamic coupling relationship between main and bypass oil-way fluid flow signals were obtained. Finally verify the feasibility of the bypass flow measurement method.
