Advantages Smaller installation space required in the machine Overall system is significantly Power density Pneumatic cylinder force capacity is heavily limited by the maximum pressure (usually up to 10 bars) that can be achieved and by the related energy losses due to the air compression. This means that to generate high forces, very big cylinder diameters and pressure levels are needed. And forces areusuallylimited to 30 kN for a size 200 cylinder. Electromechanical cylinders can always provide much higher forces compared to a pneumatic cylinder with the same sec-tion size, with a power density...

Fluid Power Replacement EWELLIXEnvironment Performance optimization, easy integration and environmental friendliness are 3 key facts leading to total cost of ownership savings. Safety Hydraulic cylinders usually work with very high pressures (up to 350 bars) and represent a potential hazard for personnel working around the system, due to pinhole leaks and improper couplings. Moreover, if mineral oil is used, they can create a potential fire hazard. For pneumatics, the situation improves but the stored energy can still be a danger during maintenance checks or unexpected system shutdowns. It is...

Advantages • Safer during inspection and service • Safer during machine operation • Power consumption close to zero while not in use • Higher efficiency in converting electric into mechanical power Efficiency: Energy losses comparison Leakages 25% Mechanical 8% Output power 6% Output powe

Advantages • Noise is generated only when operated • Noise level is usually negligible • Grease lubricant fully contained inside the actuator body • Very low heat generation Environmental Even though air is free, it can be contaminated by oil or other impurities, and needs to be filtered to avoid environmental pollution. Also, the leakages and disposal of hydraulic oil represent a significant environmental issue and a potential source of pollution. The energy losses on the whole system, especially on hydraulic, can cause ambient overheating that then has to be evacuated, causing extra energy...

Simplicity We are at a fourth era of history of manufacturing called Industry 4.0 where technologies and processes are connected in a collaborative network. Installation Pneumatic systems require many components, including hoses, pumps, valves, regulators, lubricators, and air filters. Hydraulic systems, as well, require a complex setup including a fluid reservoir, pumps, motors, release valves, heat exchangers, along with noise-reduction equipment. This means the commissioning time is also long since several parts of the system must be finetuned. Electromechanical systems only require a motor,...

Design When designing a fluid powered system, it’s important to correctly place the numerous components and to accurately define the right route for the pipes and hoses, creating constrains in the machine layout. Depending on the number of cylinders, the distance between them and the overall machine layout, the design phase can take some time as the designer also has to consider a simple installation and maintenance process. With electromechanical systems, the design process is lean thanks to few components and to the usage of electric cables only, that allow a more flexible routing and installation....

Advantages • Virtually maintenance free • Easier implementation of predictive maintenance strategies • Easier and quicker cylinder replacement • No recalibration required after cylinder replacement Maintenance Fluid powered systems require constant maintenance to achieve overall system efficiency, avoiding leaks and failures. Filtering system, valves, pipes and fittings should be monitored and serviced to improve cylinder performance over time. Moreover, manual inspection operations are required to check the system status and spot possible issues. It’s also possible to perform predictive maintenance...
