摘要： An arrangement monitors the useful properties of pressure fluids (5) in fluid-technical installations. A plurality of measured variables, each representing a useful property of the pressure fluid, are determined by a plurality of sensors (13, 15, 17) which are combined with a pump (11) to form a structural unit which can be build into a tank (3) containing the pressure fluid. The sensors (13, 15, 17) are hydraulically connected in series with the pump (11).

摘要： A backflush filter device for filter elements (22) is incorporated in a filter housing (10)having a filter inlet (18) and an outlet (20) for the liquid to be filtered. The filter elements (22) permit flow in both directions for a filtration, or backflush. One filter element (22) may be performing a filtration and, simultaneously, at least one other filter element (22) may be backflushed to clean its effective filtration surface. To assist the backflushing, a vacuum device (42) is provided. The vacuum device generates a vacuum at the filter element (22) to be backflushed. The efficacy of the ongoing backflush is increased to be able to remove even the toughest contaminants. The cleaning process uses little energy and occurs in a defined manner, such that the backflush volumes may be both specified and minimized.

摘要： A method monitors the gas prefill pressure in hydraulic accumulators. After the pressure supply to the oil side of the accumulator has been interrupted and the contents of the tank have been emptied, the current gas temperature and the current gas pressure are determined, once the temperature has equalized. The data relating to the gas temperature and pressure is telemetrically transmitted to an evaluation unit, which is spatially located at a distance, to calculate an actual value of the gas prefill pressure which corresponds to a reference temperature.
