Hydraulic Powerpack/Unit Design Components

Hydraulic Powerpack/Unit Design Components

Large, durable hydraulic power units built to operate in a variety of environmental conditions will have many design features that differ from typical pumping systems. Some standard design features include:

Accumulators: These are containers that can be connected to hydraulic actuators. They collect water from the pumping mechanism, which is used to build and maintain fluid pressure to supplement the motor pumping system.

Electric Pump: The hydraulic power pack can be equipped with a single electric pump or with multiple units, each with its own accumulator valve. With multi-pump systems, usually only one pump is running at a time.

Storage Tank: A storage tank is a storage unit designed with sufficient volume for the fluid in the pipeline to drain into it. Also, actuator fluid may sometimes need to be drained into the tank.

Filter: The filter is usually installed on top of the tank. It is a self-contained bypass unit with its own motor, pump and filter. It can be used to fill or empty the tank by activating the multi-way valve. Because they are self-contained, the filters can usually be replaced while the powerplant is running.

Coolers and Heaters: As part of the temperature conditioning process, an air cooler can be installed near or behind the filter unit to prevent temperature rise above operating parameters. Also, a heating system such as an oil-based heater can be used to increase the temperature if necessary.

Powerpack Controller: The hydraulic controller unit is the operator interface that contains the power switch, display and monitoring functions. It is required for the installation and integration of the power unit into the hydraulic system and can usually be wired into the power unit.
