HYDRAULICS – DL 8110H
Hydraulics is the science that studies the use of liquids, especially water and fluid mechanics constitutes its theoretical basis. De Lorenzo proposes two types of hydraulic benches, one of which is composed of transparent components.
Both proposed equipment is subdivided in three parts: basic level, advanced level and electro-hydraulic and all the components are printed with the standardized symbols for easy identification and with rapid connections.
The components of the transparent equipment are realized in plexiglass with the same construction techniques of the real ones.
They are supplied with hydraulic power unit. This equipment is recommended for high schools.
