Rotary transfer joints
Rotary joint for the flow of hydraulic fluid between a stationary and rotating part of the machine. Multiway rotary transfer joints : Rotary transfer joints for supplying one or more loads with pressurised
Mounting wall
its easy access. The disadvantage is how the pressure and delivery flow pulsation in the pressure fluid cause higher noise emissions at the wall, not to mention the large amount of space taken up, the extensive
Delivery flow pulsation
actuator in the form of discontinuous movement. In addition, it causes in the pump and in the hydraulic fluid a pressure pulsation.
Seal leakage
areas to be sealed, the shape and hardness of the seal and the durability of the medium. The film of fluid on the wall associated with the escape lifts the sealing lip and therefore remains on the surface
Nominal size
The details relating to the nominal size of devices used in fluid technology are key variables which do not refer to units or dimensions and do not have to be associated with any numerical variable for
Secondary measures (in the case of sound)
from resonating. Measures to reduce the transmission of pressure and flow rate fluctuations in the fluid. This includes the use of hydraulic accumulators or expandable hoses for oscillation damping and silencers
Tank
Vessel for collecting and to some extent conditioning hydraulic fluid (removal of contamination and air, quietening). Is used at the same time to remove dissipated heat , however it is only suitable for
Scraper
Valve that can shut-off the flow in both directions. In fluid technology this valve is implemented in then form of a seated or ball valve. One of the most important sources of contamination in hydraulic
Hydraulic drive systems
hydraulic energy is in general produced by hydraulic pumps, the conducting section, comprising and fluid power control devices (control elements) and the motor section in which the hydraulic energy is converted
Hydraulic spring constant
Since actual fluids are compressible, they behave like a spring when pressure is applied to them: the higher the pressure, the more they are compressed and the smaller their volume becomes. The spring
