Pump drive capacity
Power at the pump drive shaft at a given point in time or under given load conditions.
Modular design
This is when functional units or even physical units are associated with a defined type of behaviour and can be linked together based on defined rules (EDIN 19 226, Part 5).
Optical fibre technology
System whereby electrical signals are converted into light signals, relayed inside optical fibres (glass or plastic fibres) and then converted back into electrical signals ( Figure L 19 ). Optical fib
Power hyperbola
Curve based on identical (constant) power in a rectangular p-Q system Power is calculated as follows: P = p · Q
Load pressure p L
Pressure resulting from an external load (DIN 24 312).
Cost of a fluid power plant
The overall costs for a plant consist of the procurement costs A, ( Figure K 33 ) and operating costs K, which can fluctuate considerably in the field of hydraulics. They will depend primarily on over
Negative-pulse control
Reversal of a pulse valve by purging (depressurising) the piloting line. Not used very often now, because switching may also occur in the event of an unintentional pressure drop.
Absolute digital measuring system
Measuring system in which the information on the actual (absolute) position is always available. For this purpose the sensor (e.g. glass measuring scale) must provide additional information. This info
Operating defect
Defect caused by the operation of the system, such as the loosening of components, failure of safety devices, maintenance defects, consequential damage as a result of wear, corrosion, ageing etc. as w
