Pumps in which the flow rate is controlled by a slit in fixed spigots ( radial piston pumps ) or axial ( axial piston pumps ) or radial ( vane pumps ) in control discs. In principle, they are also sui

Area of hydraulics which works with mineral oil or oil-like hydraulic fluids whose key characteristics are sufficient viscosity coupled with good lubricating performance. All devices used in oil hydra

Seal designed to seal the piston rod for a differential piston or the plunger piston in relation to the outside. A great deal is demanded of them, because they need to offer an almost perfect seal und

Pumps with a finite number of displacement units (pistons, vanes, teeth) deliver a flow rate that fluctuates around an average value due to the periodic change between the suction and pressure phase.

Numerical control that contains one or more memory programmable computers. The functionality of this numeric control is essentially defined by the programming of the computer (CNC system program = seq

A binary signal (two-point signal) is a single-parameter digital signal with only two value ranges for the signal parameter, e.g. O and L (DIN 19 226).

Document that defines in detail the sequence of measures, adjustments and monitoring actions that must be undertaken to ensure the correct usage and operation of a system, provided it is correctly ins

The relative number of failures referred to the related population. It comprises three phases (Figure A 26): Early failures : At the start of the operation of an installation (running-in period). Caus

Behaviour of a drive (or other) machine from the start of motion to reaching a steady-state motion. It is dependent on the type and principle of operation of the machine as well as the behaviour of it
