Thermoplastics

Type of seal for seal applications in which the seal must remain at a distance from the surface to be sealed during specific parts of the operating sequence. For this purpose in the majority of cases

Hard-wired control, in which program changes are provided for and can be performed in a simple manner. These are controls whose program can be changed, for example by reconnecting lines, changing or r

Area of hydraulic systems, which uses the servo technology ( electro-hydraulic control technology ) to achieve highly precise hydraulic drives using suitable . The hydraulic control elements are the c

DC solenoid with an almost horizontal force-stroke characteristic curve in the operating range and which can be controlled in proportion to voltage or current ( Figure P 19 ). The latter is preferred

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
