When it comes to using adjustable nozzles with multiple machines in different locations, there are a few special considerations to keep in mind. In some cases, no water may be used at all. When the source of the flames is a flammable liquid, such as gasoline or paint, it may be advantageous to use a foam-based extinguishing agent, which stops the chemical reaction of the fire by depriving it of oxygen. All of these considerations and more can be in favor of a particular nozzle for a particular use.
SNP is the exclusive European distributor of the industry-leading Uni-Spray pretreatment spray system. This system consists of nozzles, adjustable quick-release nozzle holders, complete lifters, quick-release tube couplers and tube holders. Uni-Spray was the manufacturer that, 20 years ago, led the transition from stainless steel spray systems to high-quality plastics. Their product remains the most complete on the market, suitable for pretreatment tunnels of all sizes.
Both the inlet doors and the end fins of the nozzles are positioned by a balance between the internal pressure of the engine exhaust and the external pressure of the flow field of the aircraft. This type of nozzle is also known as a constant pressure spray nozzle or an automatic spray nozzle. It has varying water patterns and maintains a relatively constant pressure as flow rates increase or decrease. Higher amounts of pressure cause contractions that allow the nozzle to open wider, while lower amounts of pressure cause the spring to expand and subsequently tighten the nozzle.
When using adjustable nozzles with multiple machines in different locations, it is important to consider all factors that could affect performance. The type of extinguishing agent used, as well as the size and type of nozzle, should be taken into account. Additionally, it is essential to guarantee that all components are compatible with each other and that they are properly installed and maintained. By taking these considerations into account, you can ensure that your adjustable nozzles will provide optimal performance.
