Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Durchflussmessung von Schmierstoffen. Die Erfindung betrifft insbesondere eine Vorrichtung mit der der Durchfluss des für den Betrieb von 2-Takt-Großmotoren benötigten Zylinderöls gemessen werden kann.The The invention relates to a device for flow measurement of lubricants. The invention particularly relates to a device with the Flow of for the operation of 2-stroke large engines required cylinder oil can be measured.
Herkömmlich wird der Durchfluss von Schmierstoffen entweder direkt durch in den Volumenstrom des dem Motor zugeführten Schmierstoffs eingebrachte Sensoren oder berührungslos, z. B. durch Ultraschallsensoren, gemessen. Beide Verfahren weisen aber insbesondere bei mit niedrigen Durchflussgeschwindigkeiten zugeführten Schmierstoffen Nachteile auf: die direkte Messung erhöht den Leitungswiderstand aufgrund des in den Volumenstrom einge brachten Sensors, der zu einer weiteren Verringerung der Durchflussmenge des Schmierstoffs führt, wohingegen berührungslose Verfahren, z. B. mit Ultraschall, aufgrund Ihres Messprinzips regelmäßig nur bei hohen, nicht aber bei niedrigen Durchflussgeschwindigkeiten angewendet werden können.Conventionally the flow of lubricants either directly through in the flow of the motor supplied Lubricant introduced sensors or non-contact, z. B. by ultrasonic sensors, measured. Both methods have but especially at low flow rates supplied Lubricants disadvantages: the direct measurement increases the line resistance due to the volume flow into the introduced sensor, which leads to a further reduction in the flow rate of the lubricant, whereas contactless Method, for. B. with ultrasound, due to your measuring principle regularly only at high, but not at low flow rates can be applied.
Aufgabe der Erfindung ist es daher, ein Verfahren zur Durchflussmessung von Schmierstoffen, insbesondere zur Messung des Durchflusses von für den Betrieb von 2-Takt-Großmotoren benötigtem Zylinderöl, bereitzustellen, dass auch bei niedrigen Durchflussgeschwindigkeiten angewendet werden kann, ohne dass die Durchflussgeschwindigkeit beeinträchtigt ist.task The invention is therefore a method for flow measurement of lubricants, in particular for measuring the flow of for the Operation of 2-stroke large engines benötigtem Cylinder oil, provide that even at low flow rates can be applied without affecting the flow rate impaired is.
Die Aufgabe wird durch die Anlage mit den Merkmalen von Anspruch 1 gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.The The object is achieved by the system with the features of claim 1. The under claims give advantageous embodiments of the invention again.
Grundgedanke der Erfindung ist es, in einer beispielsweise einem 2-Takt-Motor Schmierstoff zuführenden Leitung wenigstens zwei Speichertanks zur Zwischenspeicherung für den Schmierstoff vorzusehen, wobei eine kontinuierliche Schmierstoffweiterleitung durch eine Steuerung dadurch gewährleistet ist, dass die Speichertanks wechselseitig befüllt und entleert werden. Ist ein Speichertank leer wird also auf den anderen Speichertank umgeschaltet, aus dem dann Schmierstoff bereitgestellt wird, ohne dass der Schmiermittelfluss unterbrochen ist.basic idea The invention is, for example, in a 2-stroke engine Lubricant feeding Line at least two storage tanks for intermediate storage for the lubricant provide, with a continuous lubricant transfer guaranteed by a control is that the storage tanks are alternately filled and emptied. is a storage tank is empty so switched to the other storage tank, off then lubricant is provided without the lubricant flow is interrupted.
Die Durchflussmessung erfolgt durch eine Logik, die die Volumendurchflussrate aus dem bei Erreichen eines vorbestimmten Füllstands aus einem Speichertank abgegebenen Schmierstoffvolumens in der dafür benötigten Zeit berechnet. Die Frequenz der Bestimmung der Durchflussrate wird also durch das Volumen der Speichertanks bzw. des vorbestimmten Füllstands vorgegeben: eine höhere Messfrequenz wird bei kleineren Speichertankvolumen erhalten.The Flow measurement is done by a logic that measures the volume flow rate from when reaching a predetermined level from a storage tank calculated lubricant volume in the time required for it. The Frequency of determining the flow rate is thus determined by the volume the storage tank or the predetermined level specified: a higher measurement frequency is obtained at smaller storage tank volumes.
Der Vorteil dieses Aufbaus ist, dass insbesondere bei niedrigen Durchflussraten keine Beeinträchtigung des Durchflusses durch die Durchflussmessung erfolgt, wobei auch bei Störungen des Systems maximale Betriebssicherheit gewährleistet bleibt.Of the Advantage of this construction is that, especially at low flow rates no impairment the flow through the flow measurement takes place, as well in case of disturbances the system ensures maximum operational safety.
