Safety of a system
system has to consider if he wants to avoid being held liable in the case of damage. The safe use of fluid-based systems is primarily the responsibility of the system designer. He must design the system so [...] the devices are selected, mounted and the pipes are laid such that risks which arise when hydraulic fluids are released (these grow alongside the hydraulic capacity), risks based on unintentional machine
Return line pressure
Pressure created by flow resistances which must be overcome when feeding back the pressure fluid (to the tank).
Response time of a cylinder
Time that is measured between the hydraulic fluid entering the cylinder and the start of the piston movement.
Absolute pressure gauge
Device that indicates the absolute pressure at a measuring point in a hydraulic fluid, referred to a perfect vacuum.
Suction line
connected to the intake port of a hydraulic pump or compressor and permits the transport of hydraulic fluid.
Flow switch
contains an electrical switch, the contact of which is actuated at a given flow of the hydraulic fluid.
Usable volume
The proportion of hydraulic fluid within the total volume of a hydraulic accumulator that can be removed without causing any damage.
Separator
Device for separating small particles of dirt from the hydraulic fluid based on other particle characteristics apart from the particle size.
Viscosity range
Range within which the viscosity of a hydraulic fluid satisfies the requirements placed on it. It is defined by operating conditions.
Inhibitor
Additive which delays certain reactions in hydraulic fluids . It is used most commonly to counter processes associated with ageing and corrosion.
