New Kyntronics Article Compares Electro-Hydraulic Actuators to Hydraulic Cylinder Actuation Systems

Kyntronics new technical article compares electro-hydraulic actuator technology to hydraulic cylinder actuation systems. The white paper includes a comparison chart of technologies.

Kyntronics new article compares technologies of electro-hydraulic actuators to hydraulic cylinder actuation systems. It details the differences in complexity, cost, noise, reliability, environmental factors, size and energy consumption.

Hydraulic cylinder actuation systems typically require a costly infrastructure that includes pumps, cylinders, hydraulic hoses, accumulators, control valves, filters, and pressure transducers or other control additions for precise position and force control. The new EHA technology is self-contained, simple to set up, and can be connected to popular network interfaces including Ethernet and CANBus.
The two different technologies share some advantages including high force density, holding position without a brake, and integral force feedback, but electro-hydraulic actuators (EHAs) offer additional advantages, as they are fully self-contained and do not require a hydraulic system infrastructure. This reduces cost, improves reliability and is very energy efficient.
According to article author Carl Richter, "Electro-Hydraulic Actuators provide an economical and easy-to-install alternative to hydraulic cylinder actuation systems."
Hydraulic cylinder systems require more time to plan to select the proper spacing and mountings for pumps, cylinders, plumbing, servo control valves, filers, conduit, and control elements. Hydraulic pumps and motors are typically over-sized and run continuously, wasting energy and creating unwanted noise. The EHA only runs when motion is required (Force on Demand), saving on energy and noise.
With the same high force density, EHA technology is a legitimate option for hydraulic cylinders.
A comparison chart of the features of both Hydraulic cylinder actuation systems and EHAs is included in the article.

The FLIR Si1-LD is an easy-to-use acoustic imaging camera for locating and quantifying pressurized leaks in compressed air systems. This lightweight, one-handed camera is designed to help maintenance, manufacturing, and engineering professionals identify air leaks faster than with traditional methods. Built with a carefully constructed array of MEMS microphones for high sensitivity, the Si1-LD produces a precise acoustic image that visually displays ultrasonic information, even in loud, industrial environments. The acoustic image is overlaid in real time on a digital image, allowing you to accurately pinpoint the source of the sound, with onboard analytics which quantify the losses being incurred. The Si1-LD features a plugin that enables you to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Transferring of images can be managed via memory stick or USB data cable. Through a regular maintenance routine, the FLIR Si1-LD can help facilities reduce their environmental impact and save money on utility bills.
