Flow rate linearity
Maximum deviation of the average flow rate signal function from the straight line of the average flow rate amplification. Stated as a percentage of the nominal flow rate .
Energy losses in hydraulics
In every hydraulic system there are energy losses in the form of pressure and leakage losses in varying degrees. A differentiation is made between (Figure E 31) : pressure losses in lines due to frict
Pressure peak
Pressure pulse that can go beyond the calculated pressure (DIN 24 312).
Teach-in programming
Programming method , in which the desired information is input by demonstrating it. This happens by performing a cycle step by step and entering the values calculated for the position, velocity etc. i
Drag flow pressure
Pressure, which builds up under certain constraints in front of a piston rod seal and which can reach several times the nominal pressure of the system. The drag flow pressure is caused by the drag flo
Surface filter
Filter which only separates off impurities at the surface of the filter element. Surface filters are designed with pores (gap) of a similar size, which means they can retain certain sizes of particle
Piston rings for sealing
The kind of piston ring associated with the combustion engine can also be found in mechanical engineering. As a piston seal installed in a hydraulic cylinder , it has the advantage of showing very lit
Filter
The main function of the filter is to hold back undissolved foreign particles in hydraulic fluid. This makes it an important part of any hydraulic system. The aim of filtering is that The wear on movi
Model of open loop system
Mathematical model of a controlled subsystem, , which describes its the static and dynamic behaviour.
