Wheel motor
Hydraulic motor , which can be integrated directly into the wheels of a vehicle. This produces a direct transfer of the force without interposing a manual transition, cardan shaft and differential gea
Solubility of gas in a hydraulic fluid
Fluids have the characteristic of dissolving certain amounts of gases. In mineral oil this ability increases linearly with pressure up to approx. 300 bar. Dalton's law states: V G = dissolved gas volu
Single or separate drive for machines
Every machine or even every cylinder , provided its movements overlap with others, has a dedicated pump with a size based on the highest load speed v k required (Figure E 13) . This means that high sp
Flow velocity in pipelines and valves
As the flow losses are determined in pipelines using the square of the flow velocity, certain velocity values should not be exceeded. These are tiered according to the pressure in the system and the p
Suction line
Line connected to the intake port of a hydraulic pump or compressor and permits the transport of hydraulic fluid.
Error threshold
Limit for the magnitude of an error that must be exceeded for the error to be indicated or so that in redundant systems the system switches over to the redundant channel (with standby redundancy). On
Controller with time delay
Controller with a delay element (e.g. PT1).
Chlorinated hydrocarbons
Aromatic or paraffinic hydrocarbons in which certain hydrogen atoms are replaced with chlorine. Low flammability is achieved here by means of chlorine (CETOP RP 100). Certain chlorinated hydrocarbons
On-stroke time of a pump
Time that a variable pump requires to adjust from zero to max. delivery flow (regulated). It depends on the adjustment mechanism, the pilot pressure and the adjustment travel, and also on the mass tha
