What is a Hydraulic Power Unit (HPU)?
A hydraulic power unit (HPU) is a device that converts mechanical energy into hydraulic pressure. It can then be used to power hydraulic machinery and components like plane hydraulics.
You’ll find that hydraulic power units are portable because they are used as ground support equipment.
What Are Hydraulic Power Units Used for?
Hydraulic power units are widely used for HPU work orders to inspect, drain, filter, and fill hydraulic fluid in aircraft systems. They are essential for keeping these aircraft systems safe and functioning optimally.
HPUs and hydraulic mules are a lot better than some other energy sources. This is because they can transmit large amounts of electric energy into hydraulic power with minimal losses, over long distances. Portable hydraulic power units are known for their reliability and can be used for demanding applications related to aviation hydraulic systems.
How Does a Hydraulic Power Unit Work?
Hydraulic power packs are driven by an electric motor or an internal combustion engine to produce power for the hydraulic pump. The hydraulic pumps are responsible for drawing hydraulic fluid from a reservoir and moving it through the hydraulic system.
These power packs rely on multi-stage pressurized networks to transfer fluid, accompanied by temperature control devices. The heat exchanger effectively manages the heat produced in a hydraulic system, preventing the fluid from reaching dangerous temperatures. Hydraulic fluid is filtered to remove any contaminants and debris.
What Are the Main Components of a Hydraulic Power Unit?
Portable hydraulic power units and hydraulic mules are portable ground support equipment. They have several, including:
- Electric Power Motor or Internal Combustion Engine
- Hydraulic Pump
- Hydraulic Fluid Reservoir
- Filtration System
- Cooling System
- Heat Exchangers
- Pressure Relief Valve
