Static behaviour
Describes the connection between the output and input variable of a transfer element, i.e. after all of the settling processes have ended. It therefore describes the stationary state of the system. Th
Controller types
According to DIN 19 225, controllers are divided according to their tasks and properties. Designation according to tasks distinguishes between the type of the controlled variable , such as the locatio
Measured signal
Representation of measured variables in the path of the signal flow by means of allocated physical variables of the same or a different type. The value for the measured signal (signal value) read off
Hydromechanical efficiency
Losses in hydrostatic input/output elements mainly caused by friction forces — which may depend on rotation speed, pressure or velocity — and by flow losses . The resulting loss torques are M c = cons
Circulation losses in hydraulic systems
In order to be ready for operation, hydraulic systems normally need the pump to continue running even if its flow rate is not needed at that time, e.g. in the loading phase of a working cycle. The pum
Suction pressure control
The delivery quantity of a piston compressor (related to the normal state) varies as the suction pressure is changed, with the suction valve raised more or less by a release valve during the compressi
MZ engine (swashplate machine)
"Torque at the cylinder"; classification characteristic based on drive kinematics for axial piston swashplate (axial piston) pump or motors whereby torque is transmitted to the cylinder drum via the p
Hydraulic bridge rectifier
1. Arrangement whereby a combination of two half bridges results in a full (Wheatstone) bridge. This is the case, for example, with the control edges of continuously adjustable valves whereby deflecti
Sliding friction
Friction that is produced when two surfaces rub against each other. Friction can vary very significantly in fluid technology, depending on Which seal material is used, Which seal shape is used, The ma
