Blowing past piston seals
On the piston seal of a double acting hydraulic cylinder, in the case of a poorly designed piston seal, pressure fluid can flow from one side of the piston to another in a short time, normally if very
Symbols
Abstract illustration in the form of graphical symbols, which display the function of a fluid device (not its construction design) in accordance with a standard or a key. The symbols were previously k
Flow switch
Devices, which contains an electrical switch, the contact of which is actuated at a given flow of the hydraulic fluid.
Control command
The signal, which brings about a state change as the result of a signal formation or signal processing.
Plug-in board
Circuit board , which contains a multiple plug, which groups all outward-leading connections of the various functions.
Stability of a hydraulic fluid
Resistance of a liquid to permanent changes of its properties in normal storage and load conditions (CETOP RP 100).
Signal state
Any possible value of a digital signal. Example: The binary values O or L are allocated to certain voltage ranges or switching states (EDIN 19 226 T 5).
Serial
One after another, bit by bit. For example, a transfer is serial if the information is passed on one after another on the same line. Opposite: Parallel
Oscillations
Exchanges between different energy forms, which take place more or less without hindrance. In hydrostatics, these are the kinetic energy of moved masses and the potential energy of the pressured liqui
