Switch-on characteristic of a solenoid
Specific time and force required on the actuated valve. The switch-on characteristic is different on DC and AC solenoids . On average the DC solenoid switches a factor of 3 times slower than an AC sol
Stability analysis
Mathematical investigations intended to demonstrate whether the damping is sufficient for a stable state in the present system. There are also theories in the form of stability criteria .
Stress relaxation
States the reduction of the tension on an elastomer (seal) at a constant deformation and constant temperature and is therefore an important measure of the residual elasticity of a seal under pressure.
Silting
Jamming or blocking of the piston caused by a build-up of particles.
Pump-flow motor
The flow rate Q of a hydraulic motor s calculated from the volume per revolution Vg, the rotary speed of the motor n and the volumetric efficiency factor ηv of the motor. Calculate the pump-flow of a
Displacement flow
Flow rate coming from the pump, which a hydraulic motor takes on, depending on its displacement volume (geometric displacement). It is calculated as the product of the displacement and the rotation sp
Non-contact seals
Sealing systems in which the two surfaces involved in the sealing process do not touch. Due to the remaining gap, non-contact seals can never seal completely. The most important representatives of non
Repeat accuracy (reproducibility)
In general : Range within which the are spread if the same input signal is repeated ( Figure W 11 ). Measurement technology : Quantitative expression of a random error, which arises if different teste
