Difference between the power supplied and the power delivered ( hydraulic efficiency ). Much of what is lost can be attributed to: volumetric losses : these are caused by incomplete filling of the pum

Measurement for the acid content of a mineral oil . It indicates how many mg of potassium hydroxide are needed to neutralise in 1 g of oil the free acids generated during operation. Since the acid con

Information on the operating viscosity characterises the viscosity range in which the entire system can operate. A differentiation is made between three key figures: Maximum start viscosity : Characte

Thermoplastics

Pressure and flow valves with digital adjustment of the pressure and the flow rate by digital cylinders or by electrical stepper motors. While only a limited number of steps are allowed with cylinder

Systems that are intended to prevent pressure equalisation between two chambers at different pressures and that are connected together by gaps. For this purpose non-contact seals ( gap seals ) or - mo

Mathematical model of a controlled subsystem, , which describes its the static and dynamic behaviour.

Pressure, which builds up under certain constraints in front of a piston rod seal and which can reach several times the nominal pressure of the system. The drag flow pressure is caused by the drag flo

Filter which only separates off impurities at the surface of the filter element. Surface filters are designed with pores (gap) of a similar size, which means they can retain certain sizes of particle

The kind of piston ring associated with the combustion engine can also be found in mechanical engineering. As a piston seal installed in a hydraulic cylinder , it has the advantage of showing very lit
