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

The heat emission PD of a reservoir is calculated from the temperature difference between the reservoir and the ambiance (To – Ta), form the heat-emitting area A of the reservoir and the heat transfer

Outline shape of a contact seal . Corresponding to the wide-ranging requirements there are numerous profile shapes that almost all have a sealing edge as a common feature. (Exception, e.g., sealing ri

Also called the apparent dirt holding capacity. Dirt holding capacity is the quantity of test dirt that must be added before a defined differential pressure Δp is reached. In addition to the α-value,

Devices that convert electrical input signals into mechanical movements (or forces/torques) that in turn actuate hydraulic control elements . They therefore form the actual between the electrical sign

Pump with two or more gear wheels with teeth on the outside that rotate engaged in each other. As a result the hydraulic fluid is pressed out of the gaps between the teeth on the outlet side, while th

A transfer element is associated with non-linear behaviour if the relationship between the output and input signal cannot be described by a linear differential equation. Non-linear signal transmitters

Delivery flow pulsation

Flow rate measurement of the Bernoulli force of a flow rate on a body, e.g. a Prandtl tube ( Figure S 78 ). This is then used to measure the static pressure p 1 and the dynamic pressure p 2 and thereb
