Sequence diagram
Graphic depiction of the movement processes within a working cycle on hydraulic drives. This can be a position-(stroke)-time diagram on which the times when the drive is moving and stationary can be s
Frequency spectrum
Reflects the frequency distribution of noise including its intensity that together with the change over time describes a noise signal.
Flange connection
The flange connection is a friction-locked, separable pipe connection comprising two flange halves and a seal. The tightening torque of the fastening screws generates the necessary sealing force. Flan
Fieldbus
Technical system comprising hardware and software that makes possible communication and the exchange of data between the devices connected to it (Figure F 8) . The devices are primarily sensors, actua
Single edge control
Control of the speed of a cylinder via control edges. Every displacement chamber has two flow resistances. With the single edge control one resistance can change, the second resistance is however cons
Piston for rapid traverse
To obtain a higher rapid forward movement speed v E with the pump designed for the operating speed, a piston with the area is arrange in the main piston and switched such that pressure is only applied
Pressure
The pressure p is the quotient of the normal force F that acts on a surface, and the area of this surface A ( DIN 24 312 ): The derived unit for pressure in the SI system is the pascal: 1 Pa = 1 N/m2.
Pressure gradient
Local increase in the pressure along the route in a steady-state flow (DIN 24 312).
Pressure drop
Time-dependent pressure change from a higher value to a lower value (DIN 24 312). The pressure drop is generally referred to a device or a section (e.g. pipe).
Digitising (quantising)
Process for converting an analogue variable x into digital variables. During this process the variable x is quantised based on a base unit where the continuous progression is assigned to an equivalent
