Abstract

Control system for use with a saliva removal system in the treatment rooms of a dental practice. The pump system has a stepless rotational velocity controller (frequency transformer without an electronic controller) for load dependent control of the suction pressure. A pressure sensor is used to measure the vacuum pressure existing in the system and a controller is integrated in the frequency transformer or an external controller to control the frequency transformer without an electronic controller.

Description

Die vorgenannte Steuerung ermöglicht es, daß an jedem Behandlungsplatz des Zahnarztes der gleiche Unterdruck zum Absaugen des Speichels im Mund ansteht, egal ob an einem Behandlungsplatz oder an 2 bis 5 Behandlungs­ plätzen abgesaugt wird. Bei den bekannten Steuerungen ist das Absaugvolu­ men an einem Behandlungsplatz meist zu stark, an zweien vielleicht richtig und bei drei oder mehr Plätzen zu schwach.The aforementioned control enables that at every treatment place the dentist has the same negative pressure to suck out the saliva in the mouth is pending, whether at a treatment center or at 2 to 5 treatment centers places is suctioned off. In the known controls, the suction volume men are usually too strong in one treatment place, maybe correct in two and too weak for three or more places.

Ein bisher benutztes Vakuumregelventil, welches man von Hand auf einen festen Wert einstellt, wird durch Benutzung eines Drucksensors ersetzt. Dieser Drucksensor regelt über einen PID-Regler einen Frequenzumformer, der die Drehzahl der Absaugpumpe stets hoch- oder herunterregelt, um einen konstanten Unterdruck im System zu gewährleisten.A previously used vacuum control valve, which you can manually on one setting a fixed value is replaced by using a pressure sensor. This pressure sensor controls a frequency converter via a PID controller, that always up or down the speed of the suction pump by one to ensure constant negative pressure in the system.

Der Einsatz liegt bei Zahnärzten und Kliniken.The application lies with dentists and clinics.
