About Digital Hydraulics

Digital Hydraulics - A precision hydraulic technology can be used by anyone

Digital hydraulic technology is the latest international trend of development. It is an upgrade from servo hydraulic technology. The key of digital hydraulic control is precision servo closed-loop control technology, but the difference is the digital hydraulic uses the machinery closed-loop and feedback control, not the electronic. Because the digital hydraulic feedback is precision machinery, so hydraulic transmission control system is simplified. Users do not need to care about what is the PID, the frequency response, valve gain, and the characteristics of complex components, users only need to focus on the target needs. Digital hydraulic technology not only greatly reduces the threshold of pollution, interference and temperature range of the threshold is also greatly improved. Digital hydraulic allows everyone to use and can make good use of.

AEMETEC's Digital Hydraulic

As the core of intelligent hardware, Internet+ and Industrie 4.0 concepts, digital hydraulic system has emerged as the shared fundamental technology to drive equipment manufacturing industry to evolve towards IT application and intelligent optimization.

As a matter of fact, an excellent automatic control system does not lie on its accurate algorithm. On contrary, no matter PID, Fuzzy logic, or advanced modern controlling technologies are adopted, the precise execution automatic control system. Digital hydraulic technology holds the key for automatic controlling systems to outperform the existing technologies to take a leapfrog development.

When it comes to digital hydraulic system, it refers to that the state-of-the-art components (cylinder and motor) correspond to electrical impulse in term of their motion features. For instance, electric impulse frequency is consistent with the speed of the corresponding oil cylinder (angular velocity of oil motor), the number of electric pulse corresponds to the movement of oil cylinder (oil motor angle); and the precision of execution device will not be changed along with the varieties in loading, oil pressure and leakage. That’s why we name such a hydraulic technology as digital hydraulic system.

Digital hydraulic system essentially aims to give the controlling right back to electricity and hydraulic power amplification. For this reason, it is the typical intelligent hardware and has been the common basic technologies for equipment manufacturing to realize "Industrie 4.0" technical revolution.
