Description
Die Erfindung betrifft eine Flüssigkeitsstandanzeige-Einrichtung für Behälter und Kessel. Es sind bereits Flüssigkeitsstandanzeiger bekanntgeworden, diese haben jedoch den Nachteil, daß sowohl zwischen der magnetischen Kupplung an dem Rohrsystem als auch an den Führungs- bzw. Gleitrollen Reibung entsteht, die zu einer erheblichen Anzeigeungenauigkeit des Flüssigkeitsstandes führt. Um diese Reibungserscheinung vollkommen aufzuheben, zeigt die Erfindung eine verbesserte Flüssigkeitsstandanzeige-Einrichtung. The invention relates to a liquid level indicator device for containers and boilers. Liquid level indicators have already become known However, these have the disadvantage that both between the magnetic coupling the pipe system as well as on the guide or sliding rollers friction occurs, which leads to a considerable inaccuracy in the display of the liquid level. Around To completely eliminate friction phenomena, the invention shows an improved one Liquid level indicator device.
Die Erfindung ist dadurch gekennzeichnet, daß die Gleit- und Führungsrollen an einer federnd angeordneten Halterung mit Magnetkern befestigt sind und der Magnetkern von einem mit Wechselstrom beaufschlagten Elektromagneten zur Aufhebung der Reibung in Schwingungen versetzt wird. The invention is characterized in that the sliding and guide rollers are attached to a spring-mounted holder with a magnetic core and the magnetic core by an alternating current applied electromagnet to remove the friction is set in vibration.
In der Zeichnung ist die Erfindung beispielsweise im Schnitt dargestellt. In the drawing, the invention is shown, for example, in section.
Es ist 1 das Schwimmeraufnahmerohr mit einer am Rohr flanschartig ausgebildeten Abdeckkappe 2. It is 1 the float mounting tube with a flange-like on the tube formed cover cap 2.
Seitlich des Rohres 1 ist ein zweites Rohr 3, welches einen viel kleineren Durchmesser hat, vorgesehen.To the side of the pipe 1 is a second pipe 3, which is a much smaller one Diameter is provided.
Dies hat den Zweck, kleine Kupplungsmittel zu verwenden, um eine wirkungsvolle Steuerung zu ermöglichen. Das Schwimmeraufnahmerohr steht über die Öffnungen cld mit dem zu überwachenden Kessel in Verbindung. Die Anzeigeeinrichtung besteht ferner aus den Führungsrollen 4, 5 und eine Halterung 6, die zwischen Zugfedern 7, 8, 9 und 10 gespannt ist.The purpose of this is to use small coupling agents in order to achieve an effective Enable control. The float receiving tube protrudes over the openings cld in connection with the boiler to be monitored. The display device also exists from the guide rollers 4, 5 and a holder 6, which between tension springs 7, 8, 9 and 10 is curious.
Es sind 11, 12 Haltebolzen für die Zugfedern und 13 ein an der Halterung 6 befestigter Magnetkern, welcher in eine rohrartig ausgebildete Halterung 15 ragt, an dessen Ende 16 eine Magnetspule 14 vorgesehen ist, die konstant von einem Wechselstrom durchflossen wird. Durch die Wechselstrombeeinflussung des Magnetkerns wird eine Schwingbewegung (Vibration) an der Halterung 6 und somit an den Führungsrollen 4, 5 erzeugt, durch die die Reibung vollkommen aufgehoben wird. Es ist 17 ein flexibles Kabel, an dessen einem Ende ein Schwimmer 18 und am anderen Ende ein Gegengewicht oder ein Magnetkern 19 befestigt ist. Der Magnetkern 19 steht bzw. befindet sich in einem magnetischen Feld der Spule a, die über Gleitrollen 20, 21 mit einem flexiblen Kabel 26 in Verbindung steht. Es sind 22, 23 Stromzuführungsfedern, 25 ein Gleichrichter und 24 eine Stromquelle. Zwischen dem Kabel 26 ist eine Zugfeder 48 mit einem den Zeiger 49 tragenden Isolierstück 27 angeordnet.There are 11, 12 retaining bolts for the tension springs and 13 one on the bracket 6 attached magnetic core, which protrudes into a tubular holder 15, at the end 16 of which a magnetic coil 14 is provided, which is constantly powered by an alternating current is traversed. Due to the alternating current influence of the magnetic core, a Swinging movement (Vibration) on the bracket 6 and thus on the guide rollers 4, 5 generated, through which the friction is completely canceled. It's 17 a flexible one Cable having a float 18 at one end and a counterweight at the other end or a magnetic core 19 is attached. The magnetic core 19 stands or is located in a magnetic field of the coil a, which has castors 20, 21 with a flexible Cable 26 is in communication. There are 22, 23 power supply springs, 25 a rectifier and 24 a power source. Between the cable 26 is a tension spring 48 with one of the Pointer 49 carrying insulating piece 27 is arranged.
Bei der Auf- und Abwärtsbewegung des Schwimmers 18 macht der Magnetkern 19 die Bewegung mit, wobei infolge der magnetischen Kupplung zwischen dem Magnetkern 19 und der Spule a das Führungskabel 26 entsprechend über die Spule a auf und ab bewegt wird. Infolge der auf die Halterung 6 übertragenen Schwingbewegung wird diese auch über die Gleitrollen und das Kabel 17 auf den Magnetkern 19 übertragen. Parallel hierzu wird durch den über die Spulen fließenden pulsierenden Gleichstrom zwischen dem Magnetkern 19 und der Innenwand des Rohres 3 eine Vibration hervorgerufen, so daß, wie oben erwähnt, eine reibungslose Auf- und Abwärtsbewegung der Anzeigeeinrichtung erreicht wird. When the float 18 moves up and down, the magnetic core 19 the movement with, being due to the magnetic coupling between the magnetic core 19 and the coil a, the guide cable 26 up and down accordingly over the coil a is moved. As a result of the oscillating movement transmitted to the holder 6, the latter becomes also transmitted to the magnetic core 19 via the castors and the cable 17. Parallel this is achieved by the pulsating direct current flowing through the coils between the magnetic core 19 and the inner wall of the tube 3 caused a vibration, so that, as mentioned above, a smooth up and down movement of the display device is achieved.
