Description

Das Dampfwärmeinhaltmeßgerät dient zur kalorimetrischen Bestimmung des Wärmeinhalts von Dämpfen und in Verbindung mit einer während der Dampfentnahme stattfindenden Druckmessung der Bestimmung des Dampfzustandes. The steam heat content meter is used for calorimetric determination the heat content of vapors and in connection with one during the steam extraction taking place pressure measurement the determination of the steam condition.

Die Messung des Dampfzustandes ist insbesondere bei der Untersuchung von Dampfturbinen zur. Ermittlung des Stufengefälles als auch bei der Untersuchung von Kolbenmaschinen zur Ermittlung des schädlichen Raumes erforderlich. Es sind nach dem bisherigen Stand der Technik keine geeigneten Meßgeräte hierfür im Handel. The measurement of the vapor state is particularly important during the investigation of steam turbines for. Determination of the step gradient as well as during the investigation required by piston engines to determine the harmful space. There are according to the prior art, no suitable measuring devices are commercially available for this purpose.

Der zu untersuchende Dampf tritt über den Dampfeintritt E durch das Düsenrohr 2 in das Gefäß I ein. The steam to be examined passes through the steam inlet E. Nozzle tube 2 into vessel I.

In dem Gefäß 1 befindet sich die. dem Dampf entsprechende Flüssigkeit. Das Gefäß mündet in das mit Skala versehene Glasrohr 3. Die Flüssigkeit steht zu Beginn der.Messung bis in Höhe der Nullmarke der Skala, und dieser Stand ist hinsichtlich seines Volumens geeicht. Die Temperatur.. der Flüssigkeit wird durch das Thermometer 4 gemessen.In the vessel 1 is the. liquid corresponding to vapor. The vessel opens into the glass tube 3 provided with a scale. The liquid is available Beginning of the measurement up to the level of the zero mark on the scale, and this level is with regard to of its volume. The temperature .. of the liquid is determined by the thermometer 4 measured.

Das Gerät arbeitet nun wie folgt: Der eintretende Dampf schlägt sich in der Flüssigkeit nieder und gibt hierbei seine Wärme an die Flüssigkeit selbst ab. Hierdurch wird eine Temperaturerhöhung und auch eine Volumenzunahme, entsprechend der Niederschlagsmenge angezeigt werden. Aus Volumen- und Temperaturzunahme ist bei bekanntem Anfangsvolumen der Flüssigkeit ohne Schwierigkeiten der Wärmeinhalt des in das Gefäß eingeströmten Dampfes zu errechnen. Hat man nun zugleich während der Dampfzunahme den Druck gemessen, so ist hieraus an Hand einer Dampftafel oder eines is-Diagramms der Dampfzustand zu ermitteln. Drosselerscheinungen haben auf die Messung mit dem Dampfwärmeinhaltmeßgerät keinen Einfluß, da bekanntlich bei Drosselung der Wärmeinhalt von Dampf konstant bleibt. The device now works as follows: The steam entering is thrown out settles in the liquid and gives off its heat to the liquid itself away. This results in a temperature increase and also an increase in volume, accordingly the amount of precipitation can be displayed. From volume and temperature increase is if the initial volume of the liquid is known, the heat content without difficulty of the steam that has flowed into the vessel. One has now at the same time during the increase in steam the pressure measured, so is from this on the basis of a steam table or an is diagram to determine the steam condition. Have throttling symptoms the measurement with the steam heat content measuring device has no effect, as it is known that with Throttling the heat content of steam remains constant.
