This application will guide you through the design of a hydraulic power unit. Features include:

  • Specifying the input loads against output loads
  • Checking performance against all operating conditions and efficiencies
  • Adding specific electric motor and pump data
  • Checking the reservoir sizing and thermal performance
  • Specifying cooling capacity

Applies to the following areas

This module applies to both mobile and industrial applications although much of the more comprehensive control features will generally only be used in industrial applications. Lower cost power units in the industrial sector are very similar to the simpler mobile power units.
