Macromolecular materials whose molecules are made up of simple, repeated molecular units (blocks). Their number determines the level of polymerisation. The materials used in fluid technology in terms

Measures which keep constant the level of what is passing through a throttle in terms of flow rate , regardless of the pressure difference which applies to it ( flow control valve ). Continuously adju

Closed loop position control system with several actuators that move synchronously. In control systems there are various ways of realising this action: in the simple form the first actuator can be ope

Cylinder to trigger a control function (e.g. to actuate a limit switch in a pressure switch ).

Describes the methodical and systematic approach to generating programs . A distinction can be made between direct and indirect programming methods ( Figure P 17 ): In addition to manual programming,

The degree of energy loss in a hydraulic system also depends on the type of flow. Flow is divided into laminar and turbulent flow: In the case of laminar flow , intended stream tube filaments run para

Power losses in pipes are caused by the in the pipe, which consists of friction losses and form-related losses — neither of which are related to pressure. As such, the efficiency of pipe can be expres

Representation, depiction of devices that are required or present in a system. The device oriented plan differs from the block diagram or signal flow diagram , which reflects the functional interactio
