Abstract
An arrangement is provided for determining the oil consumption of an oil-lubricated machine. The arrangement includes an oil circuit, which leads from an oil tank via a start line to the oil-lubricated machine and back, via a return line to the oil tank, and a balance for determining the weight of oil in the oil tank. A device for heating oil is assigned to the start line in such a way that the oil is heated to a predeterminable operating temperature for the oil-lubricated machine before reaching the oil-lubricated machine. A method for determining oil consumption is also provided.

Arrangement for determining the oil consumption of an oil-lubricated machine, comprising an oil circuit, which leads from an oil tank via a start line to the oil-lubricated machine and back, via a return line to the oil tank, and a balance for determining the weight of oil in the oil tank, wherein a device for heating oil is assigned to the start line in such a way that the oil is heated to a predeterminable operating temperature for the oil-lubricated machine before reaching the oil-lubricated machine, wherein a temperature sensor for determining oil temperature is arranged directly downstream of the device, and the temperature sensor is joined to a temperature regulator which controls the device in such a way that the oil can be brought to a predeterminable operating temperature for the oil-lubricated machine.
Process for determining the oil consumption of an oil-lubricated machine, comprising:
- feeding oil from an oil tank out to the machine and from there back to the oil tank;
- continuously gravimetrically measuring the weight of the oil volume found in the oil tank;
- wherein the oil is heated before flowing through the oil-lubricated machine to a predeterminable operating temperature for the oil-lubricated machine, and wherein blow-by gases with oil particles contained therein are diverted from an oil circuit which leads from the oil tank to the oil-lubricated machine and back to the oil tank.
