State controller
can be introduced by status monitors . In the case of the closed loop position control systems in fluid technology it has been shown that a combined feedback of the velocity and acceleration produces the
Elastomers
range between -20° and +100°C. FKM (fluorinated rubber) has high resistance to mineral oil and HFD fluids even at high temperatures (up to 200°C). FVMQ (fluorosilicone rubber) can be used over a very high
Orifice
outside the geometric cross-section constriction. As in these types of flow resistances the viscous fluid friction is very low, the flow rate is dependent on the pressure difference and not the viscosity
Cylinder
cylinders ). Membrane cylinder : The mechanical force is created by the influence of the hydraulic fluid on a membrane. Only small strokes are possible here.
Safety regulations
In terms of fluid technology there is no closed regulatory system in terms of safety technological requirements. Rather, these are distributed over a series of rules, regulations and standards of the
Directional valve
Directional valves affect the start/stop and flow direction of the hydraulic fluid, and thereby control the movement of the actuators in a hydraulic system. Their function is to direct the flow of hydraulic
Particle size
Dimensions of solid contamination elements or foreign particles in the pressure fluid. These impurities may be caused by various things: debris associated with metallic and non-metallic particles produced
Seated valve
seating element. A typical application is the Check valve . The ball prevents return flow of the fluid. As spring-loaded versions, this valve type can also be used as a Pressure-limiting valve or as a
Transfer element
l to the time derivative of the input signal ( c ); There are also elements with time delay . In fluid technology, these are normally: PT1-elements, i.e. P-elements with a 1st order time delay, in which
Inductive position measurement
Inductive sensors are the favoured choice for short lengths in fluids-based drive technology. These are passive sensors based on the principle of self-induction. If an alternating current flows through
