www.duesen-schlick.deSchlick two-substance nozzles• With the help of an atomising medium, two-substancenozzles Series 930-933 can atomise liquid to get a largespecific surface.• The atomising medium can be compressed air, gas, orsteam at 0.5 bar upwards.• External mix nozzles allow independent control of flowrate and droplet fineness.• The nozzle’s spray pattern is an elliptical flat jet.• The opening angle of the flat jet can be set with theadjusting screw on the side of the nozzle body. If thescrew is turned in to the stop, the result is a round jetof approximately 10°. As the screw is slowly turned out,the 10° round jet turns into a flat jet. Any angle up toa maximum of 90° can be set.• All individual parts are available as spares. This ensuresperformance repeatability.• Depending on viscosity, the liquid can be siphoned, fedover a slight gradient or under pressure. Within certainlimits, the nozzles in this series also function as injectors.• The liquid pressure differential can be used to controlthe flow rate on all versions. On versions with a controlneedle the needle setting can also be used to controlthe flow rate.• Depending on viscosity, flow rate, density, and surfacetension this series is also available- with control needle- with cleaning needle• Atomised spray pattern:Elliptical flat jet of 10° to 90°• Type of atomisation:- fog, down to very fine- droplet size less than 50 – 150 micronsDesign formsModel 930Borehole in liquid insert:0.3 – 0.8 mmModel 931Borehole in liquid insert:1.0 – 1.2 mmStandard Model 932Borehole in liquid insert:1.5 – 1.8 mmModel 933Borehole in liquid insert:2.0 – 2.3 mmFig. 17001All nozzle forms are available withlengthened liquid inserts.Fig. 17002Nozzle designsForm 0Basic model (with blind plug).Designed for the atomisation of liquids that are eithersiphoned or fed by gravity at a slight gradient.Fig. 17003Form 1With blind plug and swirl chamber.Designed for fine atomisation of liquids under pressure.Especially suitable for integration in textile webmoisturising equipment.Fig. 17004Form 3Supplied with cleaning needle. For fast nozzle orificecleaning during operation. Designed for the atomisationof sticky, impure, or highly viscous liquids, etc.Fig. 170052

This simplifies installation,removal, and the cleaning of individual components.• The function and spray pattern correspond to thestandard version.• All individual parts are available from stock.• The nozzle can be fitted with a liquid return and afixing block.• In comparison to the standard design, however, theversatility is less.• The nozzle is easily installed with the help of thefixing block.Fig. 1701245
