Abstract:
The present invention relates to a sensing unit for monitoring the condition of a liquid, the sensing unit comprising at least one sensor and an evaluation unit. The sensing unit is adapted to measure two or more parameters of the liquid by use of at least one sensor, where the parameters relate to at least liquid degradation or wear debris particle generation. The at least one sensor is adapted to provide at least two signals, each signal providing its values in a fashion suitable for developing a mean value and a variance different from zero over a course of at least two measurements. The evaluation unit is adapted to correlate the measured signals, and to evaluate the condition of the liquid by comparing the measured at least two parameters. Thereby, a reliable monitoring system giving continual feedback on the performance of the lubricant and the machine in an auto-correlated manner is obtained, thus allowing continual adjustments to improve uptime and machine life.
Abstract:
A sorption element 101 for removing hydrocarbon contaminants from an aqueous liquid, wherein the sorption element 101 comprises a frame structure 102 with at least one opening providing a fluid connection between an input side and an output side of the sorption element 102, each opening being filled with a sorption medium 103, comprising stacked sheets 120, 121, 122 of a sorbent material, the sheets 120, 121, 122 being bonded together by a plurality of inter- spaced line-shaped joints 130, 131 and/or punctiform joints 130, 131, wherein the sheets 120, 121, 122 of the sorbent material are arranged to extend in the direction from the input side to the output side, thereby forming a plurality of channels 108, each channel being defined by sorbent sheet material and having a feed opening 109 towards the input side and a discharge opening 110 towards the output side. A method for producing a sorption medium comprises: rolling up a first and a second web of a sorbent sheet material onto a spool member and bonding adjacent layers together by line-shaped and/or punctiform joints in one step; cutting open the rolled up material; and flattening out the rolled up material.
Abstract:
The present invention relates to an oil filtration system for purifying oil present in a reservoir, the system comprising a system inlet for receiving an inlet flow of contaminated oil from said reservoir, a system outlet for releasing an outlet flow of purified oil to said reservoir, a vacuum housing which is in fluid communication with the system inlet and the system outlet, where the vacuum housing comprises an oil filter arranged in-side said housing, which oil filter is adapted to receive the contaminated oil and to release filtered oil, a first pumping unit which is arranged upstream of the vacuum housing, where the first pumping unit is adapted to provide a flow of contaminated oil in a direction from the system inlet to an inlet of the vacuum housing at a fixed pumping flow rate, a second pumping unit which is arranged downstream of the vacuum housing, where the second pumping unit is adapted to provide a flow of purified oil in a direction from an outlet of the vacuum housing to the system outlet at a pumping flow rate, a vacuum-generating means which is connected to the vacuum housing via a pumping tube and is adapted to pump a gas filled portion of said vacuum housing, where the pumping flow rate of said second pumping unit is higher than the pumping flow rate of said first pumping unit. The present invention further relates to a transformer including an oil filtration system.
