In some cases, cleaning stations are also used for cleaning, in which cleaning medium is pumped through the component in a closed circuit using an adapter at high pressures.
Die geschilderten bekannten Verfahren zur Restreinigung und RestSchmutzbestimmung von Bauteilen haben demnach die Nachteile, dass sich Durchgangs- und Sacklochbohrungen in vielen Fällen nicht oder nur schwer reinigen lassen, dass die zum Einsatz kommenden Reinigungsmodule zumeist nur an bestimmte Bauteilegeometrien angepasst sind und häufig auch durch den geschlossenen Kreislauf des Spülmediums eine aufwendige Filtertechnik benötigen.The known methods described for residual cleaning and residual dirt determination of components therefore have the disadvantages that in many cases through holes and blind holes cannot be cleaned or can only be cleaned with difficulty, and that the cleaning modules used are mostly only adapted to specific component geometries and frequently also require complex filter technology due to the closed circuit of the flushing medium.

Alle Anlagenteile bestehen bevorzugt aus Edelstahl und sind totraum- optimiert .According to FIG. 1, a low-pressure spraying module is used according to the invention, the main components of which consist of a supply container Bl which is pressurized with compressed air from a compressed air source (line 1) and which is filled with a flushing medium (via a line 2), on the output side of the supply container Bl a pre-filter F1 connected and via lines 3 and 4 in rinsing medium communication with the supply container Bl spray lance S1, a collecting container B2, an in-line analysis filter F2, which is connected to the collecting container B2 via a line 5, and that from the after Flushing the component from the particle-loaded rinsing medium collected in the collecting container B2 filters out particles and stores them for their subsequent analysis, and there is a vacuum pump connected (not shown) connected via a line 6. All system parts are preferably made of stainless steel and are optimized for dead space.
Zunächst wird der Vorlagebehälter Bl mit gefiltertem Spülmedium über die Leitung 2 befüllt. Er kann durch den Anschluss an ein werksseitiges Druckluftnetz (Leitung 1) als Druckluftquelle mit einem maximalen Druck von etwa 6 bar betrieben werden. Die Steuerung oder Regelung des Vorlagedrucks erfolgt durch ein in der Druckluftzuleitung 1 liegendes Ventil VI. Über die Spritzeinheit Sl mitFirst, the reservoir B1 is filled with filtered rinsing medium via line 2. It can be operated as a compressed air source with a maximum pressure of about 6 bar by connecting to a factory compressed air network (line 1). The supply pressure is controlled or regulated by a valve VI located in the compressed air supply line 1. Via the injection unit Sl with
Lanze kann das Spülmedium auch langen Durchgangsbohrungen zugeführt werden. Damit die notwendige Beweglichkeit der Spüllanze Sl gewährleistet ist, ist die Spüllanze Sl über einen flexiblen Schlauch 4 an dem Vorfilter Fl angeschlossen. Zwischen Vorfilter Fl und demLance can also be used to feed the flushing medium into long through holes. So that the necessary mobility of the flushing lance S1 is ensured, the flushing lance S1 is connected to the prefilter F1 via a flexible hose 4. Between prefilter Fl and the
Vorlagebehälter Bl befindet sich in der Leitung 3 ein zweites Regel/Stellventil V2 zur bedarfsgerechten Regelung/Einstellung des Drucks und/oder der Menge des Spülmediums zum Vorfilter Fl bzw. zur Spüllanze Sl. Aufgrund der auswechselbaren Spritzlanze Sl, derenStorage container Bl is located in line 3, a second control / control valve V2 for needs-based control / adjustment of the pressure and / or the amount of flushing medium to the prefilter Fl or to the flushing lance S1. Due to the exchangeable spray lance Sl, whose
Durchmesser und Länge je nach Bauteil variieren kann, und durch die flexible Leitung 4 können auch kompliziert gestaltete Bauteile, d.h. auch Durchgangs- und Sacklochbohrungen, die von verschiedenen Seiten in das Bauteil eingebracht sind, gespült, d.h. ausgespritzt werden.Diameter and length can vary depending on the component, and the flexible line 4 can also be used to design complex components, i.e. also through holes and blind holes drilled into the component from different sides, i.e. be sprayed out.
Im Auffangbehälter B2 wird das mit Partikeln belastete Spülmedium nach dem Ausspritzen der Bauteile gesammelt. Dazu weitet sich die obere Öffnung des Auffangbehalters B2 vorteilhafterweise trichterf rmig nach oben auf. Das vom Auffangbehälter B2 gesammelte partikelbelastete Medium wird über den In-Line-Analysefilter F2 mit Hilfe der (nicht gezeigten) Vakuumpumpe abgesaugt. Das erzeugte Filter kann danach sofort untersucht und für die Restschmutzbestimmung ausgewertet werden.The rinsing medium loaded with particles is collected in the collecting container B2 after the components have been sprayed out. For this purpose, the upper opening of the collecting container B2 advantageously widens upwards in the shape of a funnel. The particle-laden medium collected by the collecting container B2 is removed using the in-line analysis filter F2 the vacuum pump (not shown). The generated filter can then be examined immediately and evaluated for residual dirt determination.
Eine nicht von der Erfindung umfasste Alternative wäre die Druckerzeugung für das Spülmedium über Pumpen, was eine aufwendige Filtertechnik für das Spülmedium nötig macht, um hohe Reinheit desselben zur garantieren. Ferner entsteht ein höherer Druckverlust, der in der Pumpen- leistung vorgehalten werden uss. Dagegen wird bei dem erfindungsgemäß eingesetzten Verfahren mit einem offenen Kreislauf gearbeitet, bei dem der Druck in einfacher Weise variabel und keine aufwendige Filtertechnik nötig ist .An alternative that is not covered by the invention would be the generation of pressure for the flushing medium by means of pumps, which necessitates a complex filter technology for the flushing medium in order to guarantee its high purity. Furthermore, there is a higher pressure loss, which is kept in the pump capacity. In contrast, the process used according to the invention uses an open circuit in which the pressure can be varied in a simple manner and no complex filter technology is necessary.
