Energy-saving is a hot topic in industry. The hydraulics industry, in particular, is putting measures in place to reduce the carbon footprint and running costs of equipment and technology. Hydraulic power packs are improving in productivity as technology develops. There are now a number of key ways in which a hydraulic power pack can be engineered for better energy efficiency.
Take a look at our guide to Hydraulic Power Pack energy efficiency and check out how recent energy developments in the hydraulics industry affect you.
New Variable Speed Pumps
Variable speed pumps are an example of a recently developed piece of equipment that helps to streamline the industrial process. Using variable speed pumps in the hydraulic system helps to reduce the footprint of this energy-intensive machinery. Variable speed pumps improve the running costs of the machine considerably, resulting in a more economical and energy-efficient product.
Correct Specification for Hydraulic Pumps
Using the right pump for your needs will improve the efficiency of the system and avoid overload. The user should specify the type of hydraulic pump needed for their purpose and use a low pressure where possible. The lower pressure helps prevent the system from becoming overloaded.
Use of Variable Displacement Pump and Compensator Circuits
The variable displacement pump converts the mechanical energy in the system into fluid energy. This happens while the pump runs and varies the amount of fluid pumped with every input shaft revolution. Pump compensator circuits also help with energy efficiency as they reduce the amount of energy lost from the system through heat and friction.
Effective System Piping
Users should plan the installation and fitting of the power unit to minimise bends. This allows the fluid in the hydraulic system to flow more efficiently around the unit. Users should also make sure the correct pipe sizes are used to decrease the pressure losses in the system which can add to energy inefficiency.
Correct Positioning and System Specifications
Ensure that users plan where pumps, motors, valves and tubes are situated before the unit is set up. These also need to be suitable for the specific power unit so that they will add to the overall efficiency of the power pack while it is working.
Use Lightweight Materials
Hydraulic systems are no different from other engineering applications in that lightweight and durable materials are preferable over heavyweight components. These materials improve the reliability of the power unit and lower the footprint. Lightweight materials put less stress on the system parts. Choose aluminium for hydraulic power packs as it has durable qualities and is low cost.
Consider Location
Choosing where to position the system helps it maintain its efficiency. Dusty environments cause more rapid erosion of system parts and problems with filters. Heat stress from the environment also results in a less efficient unit. Well-ventilated areas are preferable for keeping a hydraulic power pack running for as long as possible, at maximum efficiency.
