摘要： A motor control system for a lubricant pump motor comprises a pump system power input, a motor drive, a current sensor, a lubrication controller, and a drive controller. The pump system power input is configured to supply system power. The motor drive is configured to drive the lubricant pump motor using the system power. The current sensor is disposed between the pump system power input and the motor drive to sense an input current of the system power. The lubrication controller configured to provide motor activation signals. The drive controller is disposed to receive the motor activation signals via an isolated digital input, and to control the motor drive as a function of the sensed input current and a user-defined current set-point, in response to the activation signals.

摘要： An embodiment includes a method of monitoring a fluid pump that includes receiving time domain measurement data indicating vibrations occurring in a fluid pump, and filtering the measurement data to remove measurement data components having frequencies below a threshold frequency, the removed measurement data components associated with cyclical motions of the fluid pump. The method also includes dividing the filtered measurement data into a plurality of subsets, each subset corresponding to a pump cycle, and estimating a peak count for each subset, the peak count being a number of peaks having an amplitude that exceeds a selected amplitude threshold, the amplitude threshold associated with impacts between internal components of the pump. The method further includes comparing the peak count with an expected peak count, and determining whether the pump is in a condition selected from at least one of a wear condition and a failure condition based on the comparison.

摘要： The invention concerns a method for operating a gear pump, in particular for delivering engine oil in an oil circuit of a vehicle, wherein a delivery device is provided with at least two gear wheels, in particular with external toothing or configured as spur gears and arranged in a housing, wherein by means of the gear wheels a fluid to be conveyed can be delivered starting from at least one housing inlet through to at least one housing outlet, and wherein the gear wheels are arranged behind each other viewed in the axial direction (x). According to the invention, an adjustment device is provided, by means of which the gear wheels can be twisted and/or displaced relative to each other depending on the pressure conditions inside the housing, in particular depending on the vacuum pressure at the housing inlet and/or depending on the fluid back-pressure at the housing outlet.

摘要： A dialysis machine for the removal of toxic substances from biological fluids with agents for the decalcification of a dialysis liquid circulation is disclosed. The dialysis machine allows measurement of the degree of calcification of the dialysis liquid through the use of a blood leak detector or by measuring the dialysis machine pump flow or pump voltage. The invention also includes a process for automatically decalcifying the dialysis liquid circulation when a predetermined degree of calcification of the dialysis machine is measured.
