Description
Ein Wechselstrom kann für Heizzwecke wirtschaftlich in der Weise geregelt werden, daß die Sekundärwicklung eines Transformators mit mehreren Anschlüssen versehenAn alternating current can be regulated economically for heating purposes in such a way that that the secondary winding of a transformer is provided with several connections
■ 5 wird, oder daß der Transformator mit einem einstellbaren Luftspalt gebaut ist. Zur Regelung des Heizstromes für eine Schoopsche Spritzpistole oder Apparate mit ähnlichen Betriebsbedingungen wird erfindungsgemäß eine■ 5, or that the transformer is built with an adjustable air gap. Regarding the regulation the heating current for a Schoopsche spray gun or apparatus with similar operating conditions is according to the invention a
to Vereinigung der beiden Regelungsverfahren angewendet.to unification of the two regulatory procedures applied.
In der Zeichnung ist die Regelung des Heizstromes einer Schoopschen Spritzpistole als Ausführungsbeispiel dargestellt.The drawing shows the control of the heating current of a Schoop spray gun shown as an exemplary embodiment.
α ist der U-förmige Eisenkern des Transformators, dessen Kraftlinienweg durch das an einem Schenkel drehbar gelagerte Eisenstück b bis auf ein geringes Maß überbrückt wird. Die Größe des verbleibenden Luft- α is the U-shaped iron core of the transformer, the path of the line of force of which is bridged to a small extent by the iron piece b, which is rotatably mounted on one leg. The size of the remaining air
äo weges c für die Kraftlinien kann durch die Schraube d geregelt werden. Auf dem Kern a sitzen die an Leitungen e angeschlossene Primärwicklung/ und die Sekundärwicklung g. Ein Ende der letzteren ist an die Klemme h der Spritzpistole angeschlossen. An der anderen Seite besitzt die Sekundärwicklung g Anschlüsse i, k, m; an einen derselben kann durch den Schalthebel η die andere Klemme 0 der Spritzpistole angeschlossen werden. Beim Übergang des Heizstromes von h nach 0 durchfließt er die aus Widerstandsmaterial bestehende Heizhülse p. eo path c for the lines of force can be regulated by screw d . The primary winding / connected to lines e and the secondary winding g are seated on the core a. One end of the latter is connected to the terminal h of the spray gun. On the other side, the secondary winding g has connections i, k, m; the other terminal 0 of the spray gun can be connected to one of these using the switch lever η. When the heating current passes from h to 0, it flows through the heating sleeve p, which is made of resistance material.
Je nach dem Schmelzpunkt des zu verspritzenden Metalls wird der Hebel η auf einen der Anschlüsse i, k, m gelegt. Die Feinregelung der Stromstärke wird dann durch Änderung des Luftspalts c mittels der Schraube d erzielt. Diese Feinregelung gestattet, die Erhitzung derart zu regeln, daß das Material nach dem Durchgang der Düse gerade mit der für das Zerstäuben geeigneten Temperatur in den Bereich des Preßluftstroms kommt, und daß ein ungenügendes Zerstäuben infolge zu geringer oder ein Verstopfen der Düse infolge zu hoher Temperatur mit Leichtigkeit vermieden wird.Depending on the melting point of the metal to be sprayed, the lever η is placed on one of the connections i, k, m . The fine control of the current intensity is then achieved by changing the air gap c by means of the screw d . This fine control allows the heating to be regulated in such a way that, after passing through the nozzle, the material comes into the range of the compressed air flow at the temperature suitable for atomization, and that insufficient atomization due to too low or clogging of the nozzle due to too high a temperature avoided with ease.
