Hydraulic Power Pack: Working Principle & Uses

Hydraulic power packs are self-contained systems that replace the built-in power source for hydraulic machinery. Hydraulic power transfers power from one area to another to operate a machine. 

This compact power delivery system stores energy for hydraulic mechanisms. Understand this with an example of a battery. You can consider your hydraulic power unit as an electric battery that stores energy for a circuit to use when needed. Hydraulic power packs work the same in several industrial applications and devices, particularly where there is no direct connection to a power supply.

How Does a Hydraulic Power Pack Work?

The working principle of this power unit is based on the Pascal’s theory. This hypothesis linked the supply of electricity to the ratio of area and pressure.

A hydraulic power pack is a standalone unit made up of a drive motor, hydraulic pump, and hydraulic fluid tank. The drive motor and the hydraulic pump are connected through a shaft. The engine and pump can be mounted on and inside the oil tank. The tank size, withdrawal, feed, and key flow rates must be set to suit the job and application. 

Hydraulic power units give power via a control valve, which then powers the machine to which they are connected. Hydraulic powerpacks have a variety of valve connections. This implies that you may use the proper valves to power a wide range of equipment.

A variety of machinery relies on hydraulic units to perform their functions. If a machine is required to perform heavy or systematic lifting, it will most likely require assistance from hydraulic units.

Machines such as bulldozers and excavators require hydraulic power packs on construction sites. However, these devices are not limited to construction sites. Fishermen and mechanics both use hydraulic units. If they don’t have these power packs, how would fisherman hoist their nets and technicians lift their cars?

Hydraulic Power Pack Components & How They Work

Power Source

A hydraulic power unit charges by pulling power from an electrical source, such as a generator, an external motor, or the mains. DC power packs are powered using a renewable energy source or generator whereas AC units are simply connected to the electrical grid. Some power banks can also get their power from internal combustion engines or air motors.

Hydraulic power packs are intended to run constantly, drawing a charge from the power source as needed.

Motor

The motor draws energy into the power pack and transfers it to the hydraulic system via the control valve. Typically, the motor will transmit power through a rotating shaft.

Control Valve

Whatever specific control systems the power pack provides, it will always deliver hydraulic power through some form of control valve that connects to another machine. Depending on the specific power pack, the control valve may be susceptible to different regulating components, such as valve types – pressure, direction, and flow control.

Auxiliary components

Auxiliary components are used to connect a power pack to the hydraulic system. These components are couplings, air vents, and manifold blocks. They also include fluid control components such as suction pipes, return pipes, and reservoir tanks.
