Yes Yen – Computer Based Training (CBT) & Management Solutions for
Industrial Operation, Maintenance & Technical Skills

  • In-depth coverage on Hydraulic-principles
  • Detailed description of Components and working
  • Build-up of a circuit with two jobs
  • Extensive 2D / 3D Graphics, Models and Animations
  • Skill tests, Certificate printouts.
The Industrial Hydraulic Training Course covers Hydraulic Basics / Principles and Hydraulic Components in Explicit detail. The primary focus on Hydraulic Component and Hydraulic Circuit Animation / Graphics helps in very clearly understanding Hydraulic Operating and Working Principles. The CBT provides detailed knowledge on various components like Hydraulic Pumps, Actuators (Cylinders / Rotary Motors), Directional Valves, Servo Valves, Flow Control (Pressure / Temperature Compensation) Valves, Pressure Control Valves, etc. The Industrial Hydraulic Training Program has a dedicated module that builds up a basic Hydraulic Circuit and gives an in-depth understanding on the relevance and co-ordination of the various Hydraulic Components. Animated Cut-Sections give a Deep Insight into how Hydraulic Components work.
