One of the most important components of a hydraulic system is the power pack. For mobile applications, it is not always ideal to rely on an integrated power supply. Most machines used in construction projects, for example, use hydraulic power units as an energy source.
These portable power units vary in size and specifications. Often the requirements of the application determine the right type of unit to use. This article will list the ten vital considerations in buying the right hydraulic power units according to the intended application.
The unit will only function properly if it can provide the right amount of power and in the right sequence. In determining these requirements, the supplier or manufacturer typically takes into account the size of the machine, the actuators, the fluid volume, and the distance of the valves. Based on these factors, the supplier will recommend an off-the-shelf option or a custom-built pack.
There is no doubt that the working environment plays an essential role in the function of a hydraulic machine. Weather, elevation, temperature, and airborne contaminants all affect the machine’s performance. If the unit is intended for marine use, it may be necessary to have the manufacturer add a special coating to prevent saltwater damage and corrosion.
Location and purpose of the hydraulic equipment could also determine whether it is necessary to reduce noise. Regulations apply when using heavy machinery in highly populated and urban areas.
Efficient energy use
In some applications, it is also essential that a power pack is energy efficient. Although an energy-efficient model may cost more, you will save money in the long run, and it is a worthwhile investment.
Cost of ownership
The total cost of ownership takes into account how much you will spend on maintaining the unit. While some models may be cheaper than others, you need to prioritise quality because a more reliable product will be more cost effective in the long run.
The size of the equipment will affect the size of the power unit. There are micro-power packs which are ideal for small machines like an electric gate. For heavy-duty use, you can select from a variety of standard power units which have the capacity and output to match.
Customised or standard?
Customisation may be necessary depending on the needs of the application. A custom-built unit is usually a better option for bigger projects or in a specialised equipment installation. Alternatively, buying units off the shelf is often the go-to choice when catering to a larger order or for immediate use.
Since the power unit is key to the machine’s function, always conduct a thorough check to ensure that you are dealing with a reputable and reliable supplier.
The hydraulic industry is evolving, which means that there are innovations you need to consider when buying a power pack. Always make sure that the technology of the power unit matches that of the equipment.
All hydraulic power packs require regular maintenance. Ask the supplier about these details as well as the additional cost to conduct any maintenance and repairs on the unit.
