Non-specialized nozzle retailing platforms and no-brand standard market nozzle manufacturers tend to see nozzles through a perspective of simple, rigid machining processes – they often consider the only important requirement for a nozzle is the orifice diameter. However, the nozzle orifice diameter is not always so easily defined, take the example of the fan-shaped nozzle – its orifice is in the shape of an olive (or an eye), making it impossible to determine its orifice diameter by mere observation. In addition, despite the importance of the nozzle orifice diameter, the nozzle flow rate and spray angle cannot be determined by observation either, yet these have an impact on actual nozzle performance, among other variables and points to consider.
Generally speaking, as a professional nozzle manufacturer, at the onset of the nozzle design process we start by discussing the question of “what kind of performance our clients are looking for?” Liquids do not change in a linear fashion, and as such nozzle design relies on a specific question asked when receiving customer requirements for the design – “what kind of performance do you wish to achieve?”. As an example, if a customer requires a flow rate of 2LPM, and let us assume a orifice diameter of 1mm could be enough to fulfill such a requirement, we have to keep in mind that different 1mm orifice diameter nozzles all harbor different specifications – whether it be their angles, flow distribution and thrust – what would make each nozzle’s performance differ. As such, when choosing a nozzle, there are many different elements we ought to consider.
The majority of non-specialized nozzle manufacturers see nozzles as simple metalworking products, having their specifications simply defined by size, yet professional nozzle manufacturers would define and design nozzles and their minutiae based on spray quality. As an example: water and non-water liquids’ spray quality is not identical, and as such the specific properties of different liquids used is an element that needs to be taken into account.
In addition to the above, when considering quality control, regular machining products suppliers’ quality control lies only in inspecting whether the nozzle orifice diameter size corresponds with the expected standard. Yet when taking specialized nozzle manufacturers such as LORRIC to serve as an example – for us, mere inspection of the nozzle orifice diameter is far from enough – instead of that, prior to product dispatching, we conduct careful testing to check whether the product conforms with the expected spray quality and requirements. For that reason, professional nozzle manufacturers’ costs of manufacturing, quality control and dedicated equipment is several times that of non-professional manufacturers.
Any manufacturer who possesses the precise equipment and professional knowledge can drill orifices that conform with standards of orifice diameters. Yet the true difference when deciding upon a professional nozzle manufacturer lies in the fact that the former, upon manufacturing of nozzles, does not manufacture with a deliberate consideration of nozzle performance. The latter however, for the end goal of achieving the performance required by the customer, will make all efforts required to achieve the wanted spray quality, whether that will be through considering a specific orifice diameter, flow channels, materials and any other machining processes needed to be arranged. By only haggling over the orifice diameter, it is impossible to anticipate the nozzle’s performance. Let’s take for example two nozzles with a 5LPM flow rate, one made by a specialized manufacturer, and one made by a non-specialized one: even if the flow rate satisfies the requirements, the spray effectiveness might not adhere to time demands. A non-specialized nozzle manufacturer will tend to ask, “what orifice diameter are you looking for?”, and will attempt to solve your entire problem by just relying on the orifice diameter. On the opposite side of that though, a specialized nozzle manufacturer would ask questions such as: “How is the distribution situated? What problems were encountered on-site? Will changing a model improve effectiveness?” etc. This is exactly where lies the difference between non-specialized and specialized manufacturers who makes a wholesome consideration and takes into account the used liquid’s properties and quality as opposed to just seeing the machining size of the nozzle.
Following that, we can assess the quality, pros and cons of a supplier according to these standards. As a customer, whenever you encounter problems, in what manner and through what kind of attitude does the supplier offers its services? A supplier should not avoid problems when these arise – he should communicate in a logical manner, and not have a limited view of seeing the nozzle orifice diameter as the only relevant element. We in LORRIC hope our customers would communicate with us their needs and requirements, so we can create a discussion regarding what are the best product designs that could fulfill their requirements, and not approach discussions with conclusions already in mind. Taking on the role of a nozzle manufacturer, we at LORRIC have our limitations, however we will to the best of our ability use our expertise and technical ability for the end goal of having our customers satisfied. The metalworking attitude that espouses a limited “orifice diameter specification only” kind of consideration simply does not correspond with LORRIC’s ideals and product philosophy.
