Abstract
In a method for monitoring a pump arranged in a flow path to pump a fluid, the temperature of a fluid is regulated by a tempering element during the operation of the pump. The regulation of the temperature may include detecting at least one status point which is formed from an energy supplied to the tempering element and a temperature slope of the tempering element. The status point may be determined in a hazard range by checking whether the status point is located outside of a normal status range, which means that the lifespan of the pump is limited.
Claims18
A method for monitoring a pump arranged in a flow path and configured to pump a fluid, a temperature of the fluid being regulated by a tempering element during operation of the pump, the method comprising:
- detecting at least one status point formed from a tempering energy supplied to the tempering element and an element temperature corresponding to a temperature slope of the tempering element;
- and
- determining whether the at least one status point is situated in a hazard range located outside of a normal status range, wherein the at least one status point being situated in the hazard range is indicative of a lifespan of the pump being limited.
An ink printing apparatus, comprising:
- a pump arranged in a flow path and configured to pump ink;
- and
- a processor configured to regulate a temperature of the ink using a tempering element during operation of the pump, wherein regulation of the temperature includes:
- detecting at least one status point formed from a tempering energy supplied to the tempering element and an element temperature corresponding to a temperature slope of the tempering element;
- and
- determining whether the at least one status point is situated in a hazard range located outside of a normal status range, wherein the at least one status point being situated in the hazard range is indicative of a lifespan of the pump being limited.
