Data correlation model for hydraulic fluid filter condition monitoring

Autor: Jokinen, Anton, Calonius, Olof, Gorle, Jagan, Pietola, Matti

In fluid power systems, one of the most common causes of failure is contamination of the hydraulic fluid. Without filtering the fluid gets contaminated with harmful particles over time, which will cause excessive wear of components or even block moti

Experimental Study on Fast and Energy-Efficient Direct Driven Hydraulic Actuator Unit

Autor: Koitto, Teemu, Kauranne, Heikki, Calonius, Olof, Minav, Tatiana, Pietola, Matti

Publikováno v: Energies, Vol 12, Iss 8, p 1538 (2019)

In this experimental study, a Direct Driven Hydraulics (DDH) system of the closed circuit type was utilized for cyclic vertical actuation in heavy load material handling. The actuator was controlled by a speed-controlled fixed displacement pump. The
