2 INNOVATIVE NOZZLE TECHNOLOGY MAKES INNOVATIVE SURFA TECHNOLOGY POSSILE eing successful means making the most of all opportunities that the market offers. Whether we re checking the paint on a highend sedan or how well a dishwasher works surfaces make or break our first impression of product quality. Along with the quality aspect, surface characteristics are also decisive when it comes to function. One good example: the sophisticated pretreatment steps in the PC and photovoltaic industries. ut no matter what the sector, all surface treatments include work steps such as cleaning, rinsing, drying, etching, or applying. To achieve optimum results, the required nozzles must be a perfect fit for the respective application. This also includes perfect production processes. Particular importance is attached here to increasing product quality and using more rational production methods. Nozzle and spraying technology offers many different, often surprisingly effective, possibilities of performing such tasks. Lechler can support you in mastering these tasks with an extraordinary potential in terms of experience, ideas and innovative technology. This demands a high degree of expertise, as well as a broad range of suitable products. Additional knowledge and experience in surface technology applications is particularly helpful, as this simplifies the planning process and enable confident decisionmaking. What s more, Lechler carefully documents the performance data for all nozzle types so you can easily access all relevant data in advance. 2

4 LECHLER NOZZLES ARE AN INTEGRAL COMPONENT IN PRETREATMENT AND PAINTING SYSTEMS Nozzles for water jet cleaning DEGREASING RINSING In pretreatment and painting systems, water jet cleaning is often employed as an automated process. Flat fan nozzles and tonguetype nozzles with eyelet clamps are the main variants used for this. The components pass through several process steps in which they are treated with various fluids. These include, for example, aqueous alkaline solutions and deionised water. Eductor nozzles are also used under water, the purpose of which is to prevent sedimentation. AGITATING FRESH WATER IMMERSI IMMERSION ATH 1 RINSING DEGREASING Nozzles and installation possibilities of pretreatment For this application, Lechler supplies many different nozzles and installation possibilities (see MEMO SPRAY, EasyClip and couplings, spacers and end caps for pipe installation). 4

5 Nozzles for the rinsing zone At the end of a painting line, the components pass through a rinsing zone. There, surplus paint particles that are still mechanically attached are washed off. This is done according to the cascade principle, i.e. in several stages with increasingly clean rinsing agent until deionised water is used.

7 Nozzles for tool cooling, tool lubrication and chip removal For this task it is crucial that the nozzles spray in the correct location so that the best cooling or lubrication effect is achieved. Series 676 nozzles (for example) provide the possibility of adjustment with the aid of a ball joint. In CNC machining centres, tank cleaning nozzles that clean the machine's entire interior are also used for chip removal. Nozzles for surface pretreatment Flat fan nozzles are typically used in many stages of automobile pretreatment. The MEMOSPRAY and EasyClip nozzle systems are particularly common. Nozzles for use in washing installations In this application it is crucial that the nozzles spray in the correct location. Lechler offers a wide range of different flat fan nozzles. These also include highpressure nozzles and tonguetype nozzles. Selecting the correct nozzle enables the cleaning result and water consumption to be balanced. Nozzles for leak testing efore they are delivered, cars must be checked to ensure that they are well sealed against rain and moisture. This involves spraying them from all sides using full cone and flat fan nozzles. Here the rain intensity settings range from gentle rain have to pass through a car wash.

8 CLEANING SYSTEMS ARE FITTED WITH LECHLER FLAT FAN AND TONGUETYPE NOZZLES Nozzles for the prewash The purpose of the prewash is to soften the soil. Flat fan nozzles or tonguetype nozzles with a wide spray angle and a low flow rate are preferred. Nozzles for the main wash The main wash requires highimpact flat fan nozzles or tonguetype nozzles. The spray angle should be 30 to 45 degrees. Their sharp jet means that tonguetype nozzles are ideally suited to the low pressure. Highpressure flat fan nozzles differ from lowpressure nozzles by virtue of their hardened nozzle mouthpiece, which gives these nozzles a longer service life. Nozzles for sill and wheel washing The lower third of the vehicle is mostly where soil is found (e.g. impacted insects). A high impact is crucial to removing this type of soil. We recommend highpressure nozzles with a narrow spray angle. 8

9 Nozzles for applying wax Wax should be applied as evenly as possible. This requires a defined nozzle arrangement. For this we recommend our series 652 in conjunction with a retaining nut and eyelet clamp. Manifolds fitted with this series distribute the water very evenly. Nozzles for rinsing Rinsing is the last stage before drying. This requires small droplets that run off the vehicle quickly. Flat fan nozzles with a very low flow rate are used in most cases. The nozzles are easy to align in conjunction with a bayonet cap and a ball joint. Arrangement of lowpressure flat fan nozzles Lechler flat fan nozzles give you a linear impact with even droplet application. A prerequisite for this is that the spray widths overlap by approximately 1/31/4. Here the nozzles should be aligned approximately 5 to the pipe's longitudinal axis in order to prevent the sprays from being interrupted. 9

10 LECHLER NOZZLES ARE USED IN MANY FIELDS IN THE PHOTOVOLTAIC AND PRINTED CIRCUIT OARDS INDUSTRY Rotating cleaning nozzles for printed circuit board manufacture Rotating cleaning nozzles for printed circuit board manufacture series Rotating cleaning nozzles are used in horizontal continuous throughput systems for printed circuit board manufacture. The nozzles are made entirely of PVDF, which makes them optimally suited for use in sulphuric acidbased applications. Nozzles for alkaline texturing Flat fan nozzles in several seriesconnected modules are used in this process. Nozzles made of PVDF are preferred, because they are resistant to the chemicals used. 10

11 Circuit board manufacturing Developing, etching, stripping. In a typical inner layer line for manufacturing circuit boards, the resist is developed in the developer, the bare copper is sprayed with an acidic etching solution in the etching module and is removed down to the base material, and the resist is stripped off by using an alkaline solution. This involves the use of many types of nozzles that are already familiar, such as series 646 bayonet quicklocking system. Wafer cleaning After the sawing process, the wafers are gently cleaned with full cone nozzles. The cleaning medium is sprayed onto the individual wafers, thereby achieving a homogeneous cleaning result across the entire surface. Nozzles for wafer moistening After the sawing process, the wafers are moistened with hollow cone nozzles. Hollow cone nozzles produce a fine spray mist that settles on the wafers. This ensures that no impurities dry onto the wafer, thereby also ensuring an efficient wafer production process. 11

12 PART CLEANING WITH LECHLER FLAT FAN NOZZLES AND TONGUETYPE NOZZLES Oil sump cleaning Cleaning engine pistons Duallane continuous cyclic cleaning system for cleaning aluminium engine pistons. Increasing volumes require efficient and reliable nozzles. Series 612 nozzles can be used if only a small installation space is available at the same time. Continuous cleaning system for aluminium oil sumps, foursided spraying. Simple installation and quick replacement of nozzles enable the system's maintenance costs to be reduced. Deburring Highpressure water jetdeburring aided by a robot. A notable feature of flat jet nozzles is a very shallow jet depth, giving them a particularly high cleaning effect. 12

13 PROFESSIONAL RINSING TECHNOLOGY WITH LECHLER NOZZLES Cleaning oven racks Washing system for cleaning oven racks used in bakeries, for example. Series 612 PVDF flat fan nozzles for pressing into pipes and series 632 stainless steel flat fan nozzles with a retaining nut and eyelet clamp are used to spray the cleaner onto the racks in foam form. The nozzles are used for rinsing clean in a downstream process. Conveyor belt dishwashers Lechler series 612 PVDF flat fan nozzles for pressing into pipes are used for freshwater rinsing in conveyor belt dishwashers in order to remove any remaining suds from the objects being washed. This requires homogenous water distribution in order to achieve an optimum and constant cleaning result. 13

14 WHAT YOU SHOULD KEEP IN MIND WHEN PLANNING Nozzle selection criteria: 1 Impact 2 Spray angle and spraying behaviour Impact surface and jet shape 3 Liquid distribution The most important criteria that must be taken into account when selecting nozzles are listed below. Spraying distance Pressure Flow rate Jet depth 4 5 Droplet sizes Factors influencing the temperature behaviour of nozzle materials 6 Material and wear 1 Impact The force of impact when using of a liquid jet on a surface plays an important role in surface technology. The ratio of the force (F) to the surface (A) is referred to as the impact (I). bar MIN MAX bar MIN MAX bar MIN MAX Impact force I = = Impact surface F A N m 2 The following explains the parameters with which the impact can be influenced. l/min l/min h l/min Impact surface and spray angle The impact surface is the area where the droplet strikes. The smaller the surfae area, the greater the impact values. Nozzles with high impact are, for example, solid stream nozzles and flat fan nozzles with a narrow spray angle. 1/2 h Pressure Increasing the connected pressure results in an increase in the spray impact. Doubling the pressure while maintaining the same flow rate results in a doubling of the impact. Comparison of the cleaning result of three nozzles with identical pressure and flow rate. Pressure increase Initial situation Flow rate increase Flow rate Increasing the flow rate by using a larger nozzle increases the impact, assuming that the other parameters (spray angle, pressure and medium) remain the same. MIN MAX bar l/min MIN MAX bar l/min MIN MAX bar l/min Comparison of the cleaning result of three nozzles with pressure or flow rate increase. 14

15 Spraying distance (vertical distance to the nozzle) A 1 A 2 Strahlbreiten spray width Winkel angle 2 x h With a flat fan nozzle, doubling the distance would ideally result in a quadrupling of the surface area sprayed. Theoretically, for atomization nozzles, the greater the distance the greater also the surface area sprayed, resulting in the impact being reduced accordingly. The spray angle and jet depth ensure that the sprayed surface area becomes larger as the spraying distance increases. In theory, the following applies to flat fan nozzles: If the spraying distance is doubled, the sprayed surface area quadruples. Consequently, the impact decreases fourfold. hα Spray depth When flat fan nozzles are used, the impact that can be achieved depends greatly on the quality of the spray. For example, using special jet geometries (Lechler highpressure flat fan nozzles) or a high flow quality, a narrower spray depth can be obtained. Assuming that the other parameters (pressure, flow rate, spray angle and medium) remain the same, a narrower spray depth results in a higher impact. Impact [mn/mm²] YAchse YAchse XAchse XAchse Comparison of the spray depth of a highpressure flat fan nozzle 1 with a standard flat fan nozzle Spray angle and spraying behaviour Depending on the version and job, singlefluid nozzles are available with differently stepped spray angles from 0 (solid jet nozzles) to 3 (tankcleaning nozzles). The spray angles quoted by Lechler apply close to the nozzle and in a still atmosphere. Gravity and flow processes in the ambient atmosphere alter the spray pattern. Depending on the version, singlefluid nozzles can spray the liquid as a hollow cone, full cone or flat fan. Height of the nozzle position mm Changing the nozzle pressure The solid jet nozzle does not spray, but rather produces a closed jet that hits at a concentrated point. The jet only begins to break up after some distance. Twinfluid nozzles have a narrow spray angle of approximately 20 due to the high speed at which the compressible medium exits. However, as the distance from the nozzle increases, the spray pattern becomes increasingly less sharply defined. Twinfluid nozzles normally produce full cone or flat fan spray patterns, and some versions can be changed over accordingly. The diagram above illustrates how height influences the spray pattern mm Distance h 1.5 x h 2 x h 3 x h 4 x h Area A 2.25 x A 4 x A 9 x A 16 x A Impact I I / 2.25 I / 4 I / 9 I / 16 Very low pressure Spraying direction Optimum pressure Very high pressure Spraying upwards Spraying downwards Horizontal spraying

16 WHAT YOU SHOULD KEEP IN MIND WHEN PLANNING 3 Liquid distribution 4 Droplet sizes 5 Factors that influence the case of nozzle use. The main temperature behaviour of nozzle materials In coating processes, for example, it is attached to the homogenous distribution of the sprayed liquid. In order to obtain an even liquid distribution, several nozzles must be arranged next to each other because one nozzle alone would produce a parabolic liquid distribution as standard. The arrangement of several nozzles enables an almost even distribution to be obtained by overlapping. Twinfluid nozzles can produce very fine to extremely fine droplets, this being mainly dependent on the flow rate ratio of the compressible medium being used (m³/h) to the atomized liquid (l/min). The greater this ratio, the finer the atomization. In the case of singlefluid nozzles, the droplet spectrum is determined primarily by the pressure, the nozzle design and the flow rate. Increasing pressure results in finer atomization, but mostly only up to a certain level. A distinction must be made here between lowtemperature behaviour and hightemperature behaviour. Applications with temperatures up to 140 C are very common, because this is the range within which for example most cleaning applications and sterilisation processes fall. Applications with higher temperatures are rare, and applications at very low temperatures are even more rare. The general temperature information from material data sheets must always be scrutinised for every single factors that influence the suitability of a nozzle material at higher temperatures are: Pressure and the associated mechanical stress type along with chemistry and time. Chemical processes can be more aggressive at high temperatures. A material may be able to withstand them if this temperature occurs for a short period only. In all materials, high temperatures result in reduced strength values. The mechanical stress type must therefore also be taken into account in highpressure applications, in particular. In addition, vibrations in the system can cause premature failure. Chemistry (accelerated by high temperatures) Pressure and mechanical stress (e.g. vibrations) Measuring the distribution The liquid distribution in a measuring plane is determined by collecting the volume of liquid in a combination of Plexiglas cylinders. The filling level of the individual cylinders is determined completely automatic. This measuring process is also suitable for recording the liquid distribution of a nozzle across a moving measuring plane.this enables conveyor belt spraying to be simulated, for example. Provided that the pressure and flow rate are the same, hollow cone nozzles produce very fine to fine droplets, full cone nozzles produce somewhat coarser droplet spectrums and flat fan nozzles have the coarsest droplet spectrum. If we compare nozzles of one series at a particular pressure, nozzles with a lower flow rate produce finer droplet spectrums than nozzles with a higher flow rate.

17 6 Material and wear Signs of nozzle wear Nozzle wear depends primarily on the conditions of use and the nozzle material. Normally, the nozzle's liquid discharge opening wears as a result of material abrasion. The following conditions of use can speed up wear: Operating the nozzle above the recommended pressure range Solids in the liquid and also hard particles The use of chemically aggressive substances (see figure) Nozzle wear becomes apparent from a noticeable increase in flow rate. The cause of this is the enlarged cross section of the liquid opening that results from material abrasion. This means that if a pressure is permanently set, more liquid is discharged than it was originally intended. The result of this is higher fresh water and waste water costs. Fig. 1 shows an example of a heavily corroded spray ball. Fig. 1: Chemical corrosion of a spray ball Fig. 2: Wear of a full cone nozzle The nozzle body can also wear from the outside if the nozzle is used in a harmful environment (corrosive gases, radiation, temperature). The diagram below shows the factors that influence nozzle wear. Material wear In most cases, excessive wear can be counteracted by selecting a different material. One of the most common cases is the atomization of a liquid with a solid component. Such particleladen liquids cause significant wear if the particles have a greater hardness than the nozzle material (Fig. 2). The table shows different materials and their average Vickers hardness. The values are for the purpose of rough estimates only.
