Abstract
Es wird ein Verfahren zum Betreiben einer zur Abgabe einer Flüssigkeit vorgesehenen Hochdruckvorrichtung (1) beschrieben, die insbesondere ein Wasser-Hochdruckreiniger sein kann. Bei dem Verfahren wird der Flüssigkeit mindestens ein Zusatzstoff beigemischt, beispielsweise ein Reinigungsmittel. Erfindungsgemäß wird der Zusatzstoff der unter einem Eingangsdruck stehenden strömenden Flüssigkeit stromaufwärts vor einer Pumpe (3) der Hochdruckvorrichtung durch eine Beimischeinrichtung (14) beigemischt und anschließend gemeinsam mit der Flüssigkeit von der Pumpe unter einem gegenüber dem Eingangsdruck erhöhten Ausgangsdruck ausgegeben. Nach diesem Verfahren können auch für herkömmliche normale Wasserdrücke geeignete Beimischeinrichtungen verwendet werden, um in Hochdruckvorrichtungen Zusatzstoffe beizumischen. Es werden auch eine nach dem Verfahren arbeitende Hochdruckvorrichtung sowie ein zweckmäßig angepaßtes Beimischgerät (14) beschrieben. The invention relates to a method for operating a high-pressure device (1) provided for dispensing a liquid, which device can in particular be a high-pressure water cleaner. In the method, at least one additive, for example a cleaning agent, is added to the liquid. According to the invention, the additive of the flowing liquid under an inlet pressure is admixed upstream of a pump (3) to the high-pressure device by an admixing device (14) and is then dispensed together with the liquid from the pump under an outlet pressure that is higher than the inlet pressure. According to this method, admixing devices suitable for conventional normal water pressures can also be used to admix additives in high-pressure devices. A high-pressure device operating according to the method and a suitably adapted admixing device (14) are also described.
