Piston seal
Seal at the piston for a cylinder . With single-acting cylinders ( plunger ), the piston is only subjected to pressure on one side so only needs sealing in one direction in most cases. For hydraulic cylinders
Tank
degree (Table B 1) . As the tank is manufactured of thin material, it must not be in physical contact with the pump to prevent noise propagation. Tanks mostly have a breather filter that connects them to the
Algorithm
estimated values in steps and Recursive algorithms that recalculate the estimated values during each step with the inclusion of a new measured value set while using information from the previous steps. They are
Time constant
and the valve behaviour in the subsystem does not play a role) or in the case of comparable elements with an increase according to an exponential function. The time constant results as the inverse of the
Diagnostic systems
(Figure D 10) . Specifically, this means: Checking the settings and operation for errors in the dialogue with the user, Detection of errors in the function of devices and systems, Localisation of errors, i.e [...] g. due to malfunctions from wear (early detection of damage), Indication or errors in the dialogue with the user. There is a series of possible solutions for setting up diagnostic systems - depending on
Control
Devices and functions involved in with the task of performing the spatial coordination and synchronisation of the individual sub-functions in a process. The sequence of all sub-functions is to be stored [...] elements of the open loop control system are operated under control. This is often the case, for example, with numeric controls. Distinguishing features of controls include the representation of information (
Status monitors
that end, a mathematical model of the drive in the form of a master loop is developed and recreated with the aid of a permanently running simulation. Equally, this model makes corrections if differences
Starting performance of hydraulic motors

Water hydraulics
be used. This statement applies above all to gap seals that produce excessively high leakage losses with pressurised water. For this reason valve plate-controlled pumps must be replaced by valve-controlled
Electromagnetic compatibility
addressed by means of suitable measures, that is by screening these components. For this purpose materials with high permeability are used. The most widespread method is screening cables that carry signals. Here
