Filter tissue
Tissues comprise any number of layers on top of each other that are made by the irregular arrangement of fibres (randomly orientated fibre tissue). As a consequence a large number of small, but irregu
Pump drive capacity
Power at the pump drive shaft at a given point in time or under given load conditions.
Corner power
Highest hydrostatic power of a pump/motor/ transmission that is given by the max. flow rate and the max. pressure (Figure E 1) : P E = Q max · p max = M 2 · 2πn 2. On constant pumps and variable pumps
Flow rate linearity
Maximum deviation of the average flow rate signal function from the straight line of the average flow rate amplification. Stated as a percentage of the nominal flow rate .
Energy losses in hydraulics
In every hydraulic system there are energy losses in the form of pressure and leakage losses in varying degrees. A differentiation is made between (Figure E 31) : pressure losses in lines due to frict
Pressure peak
Pressure pulse that can go beyond the calculated pressure (DIN 24 312).
Teach-in programming
Programming method , in which the desired information is input by demonstrating it. This happens by performing a cycle step by step and entering the values calculated for the position, velocity etc. i
Opened control circuit
In some test procedures on control processes, the control circuit is "opened". As a result an input and an output are produced at the interface. The opened circuit can then be treated as a single cont
Relative delivery fluctuation δ
Fluctuations of the flow rate of hydrostatic displacement machines resulting from the final number of displacement units and their sinusoidal working patterns ( Table U 3 ). It is expressed in the for
