The flow rate in a hydraulic system with a variable pump and appropriate adjustment corresponds to the requirements in accordance with which the adjustment functions. The term impressed, i.e. pre-defi

Special pressure switch valve with the task of switching the constant pump, which charges a hydraulic accumulator , to pressure-free circulation as soon as it reaches its charging pressure and to swit

On reaching a set pressure these switches actuate a normally open or normally closed contact. Limit switches are predominantly installed in pressure gauges ( Contact pressure gauge ). A differentiatio

During the initial commissioning or repeat commissioning, every hydraulic System must be flushed to remove residual foreign particles (shavings, scale or other contamination) from the system. The flus

With all hydraulic motors of the vane and piston type that have an odd number of displacement chambers, the smaller and larger section will find themselves within the pressure range on an alternating

Pressure transducer that can measure the absolute pressure . For this purpose the side opposite the pressure to be measured is hermetically sealed as a reference chamber (e.g. with a glass plate or gl

The dynamic viscosity is a specific variable for every fluid and that for Newtonian fluids is dependent on the temperature and the pressure. Its unit is Pa · s. The old unit P (cP) is no longer allowe

The cumulative efficiency of a filter describes how effective a filter is in retaining solid particles. According to ISO 4572 it is defined by ε x = filter cumulative efficiency for particles larger t

Error in the of a which is below the response threshold of the continuously adjustable valve . Normally, less than 5% of the valve current is needed to bring the speed of a closed circuit position con
