Return line pressure
Pressure created by flow resistances which must be overcome when feeding back the pressure fluid (to the tank).
Suction line
Line connected to the intake port of a hydraulic pump or compressor and permits the transport of hydraulic fluid.
Mini measuring device (for on-line operation)
measurements will subsequently need to be taken for inspection purposes. The mini measuring device (for on-line operation) consists of a measuring coupling attached to a device or fitting and which enables it to
Linear control signal
Here, linearity refers to the relationship between the input measured variable (e.g. distance, pressure) and the electrical , which should remain as constant as possible. Where this is not the case, i
Loop line
Ring-shaped (loop) hydraulic fluid line to supply multiple consumers. Compared with a stub line, the loop line enables: a balanced supply of pressure, i.e. there are smaller pressure fluctuations and smaller [...] sections with the same flow rate or pressure drop. Compressed air networks are often designed as a loop line. In hydraulic systems, loop lines are used, for example on ships and in large-scale water hydraulic
Hose line
Hose cut to length, with the necessary connection fittings on both sides.
Return line
Line to feed the hydraulic fluid back to the container after the energy has been transferred. As with the Return line filter it must be designed according to the largest flow rate and not according to
Leakage line
Line which returns leaked fluid to the container. Its dimensions should ensure this is possible at all times with hardly any pressure — even at low temperatures.
Two-line system
high-pressure, in order to save energy. In hydraulic systems, the low-pressure line provides 20 to 30 bar, while the high-pressure line offers 200 to around 350 bar.
