Speed control circuit
Control circuit that has the task of adapting the rotation speed (e.g. of a hydraulic motor) as a controlled variable as accurately as possible to a setpoint. This action can be undertaken by changing
Pressure drop-flow rate chart for valves
Provides information on the magnitude of the Δp of directional and check valves depending on the flow rate Q (Figure D 78) . The pressure drop-flow rate chart is an important parameter for assessing a
Safety circuit
Circuit, which prevents undesired and/or hazardous operating states. The scope and design of the safety circuits for certain systems are prescribed by the German Institutions for Statutory Accident In
High speed exhaust valve
Shuttle valve, which is opened by the feed line pressure in the direction of the consumer and releases the exhaust connection when switching due to the consumer pressure ( Figure S 31 ).
Noise level addition
As logarithmic ratios, noise levels cannot be directly added together. Rather, the corresponding energies or noise intensities must be added together ( Figure S 12 ). The determination of the total no
Suction throttle control
Throttle units are built into the suction line of hydraulic pumps and compressors to specifically influence the filling of pumps or the compression pressure in the case of compressors. The suction thr
Noise level
Energy density of an interfering signal in proportion to the useful signal.
Parallel processing
Operating mode whereby several functional units process separate orders or parts of the same order in such a way that the processes involved run in parallel (DIN 4400).
