Sealing profile
initiation of the sealing action. On elastomer seals this preload is increased in proportion to the fluid pressure ( automatic sealing ).
Servo technology
that convert a weak input signal into a greatly amplified, proportional (power amplification). In fluid technology : Servo technology stands for an area that uses a power amplifier and a feedback (i.e.
Cavitation erosion
of cavitation erosion is much higher when water rather than mineral oils is used as the pressure fluid. Cavitation erosion is a form of particle jet erosion .
Comparability
The more dependent one becomes on determining parameters of fluid devices and systems through trial runs, the more important it is that these results are comparable. Otherwise, the different products will
Equivalent bulk modulus
Takes into account along with the compressibility of the pressure fluid also the elasticity of the surrounding components as well as the connection line between the valve and . The equivalent bulk modulus
Swelling of sealants
Increasing the volume of an elastomer seal through the action of the hydraulic fluid. The height of the swelling is different, depending on the seal materials . For example, polyamide swells strongly in
Closed circuit
Basic design for a hydraulic drive in which the fluid circulates from the pump to the actuator and from there straight back into the suction line of the pump. The main difference between this and an " [...] " open circuit " is that the hydraulic pump in a closed circuit is fed directly by the hydraulic fluid returning from the actuator (hydraulic motor). This effectively "clamps" the pump from both the suction
Flat seals
materials, such as rubber, PTFE, It, asbestos substitute and others. Flat seals are rarely used in fluid technology unlike in motion technology, pipework manufacture etc.
Control in the power range
part of the overall control system of a plant, which is to control the compressed air or hydraulic fluid. in terms of direction, strength and pressure potential from the pump to the cylinder (motor). Its
Optimising the controller
A controller, in fluid technology must be configured through fine tuning of the various parameters (e.g. P-component, I-component, etc.) or for state controllers of the amplifiers such that the system
