Technical Description
The THYYC-E1 is designed for the experiments covering courses of Hydraulic Drive which addresses the requirements of colleges or vocational schools. In the hydraulic drive system, the basic principles and components of governing valve, reversal valve, flow control valve, unidirectional valve and spillover valve are introduced; the hydraulic pump, characteristics of valves for three control mode and flow-controlled speed governing are introduced as well. The THYYC-1 is available with the features of follows:
Module concept adopted in valves assembly, consisting of three work surfaces;
Multi-control mode (manual, PLC+ touch screen and PC with MCGS);
Innovative design for low noise;
Complete coverage of experiments required on the curriculum;
Components and hose in conformity with industrial standards;
Safety being paramount
