Selecting the proper fan nozzle type requires consideration of the following:
【1】Application scenarios: Different application scenarios have different requirements on the spray effect and impact force of fan nozzles. For example, the fire protection industry requires fine and uniform fog shapes for fire prevention and fire fighting, while cleaning cars, carpets and other places requires water jets with impact.
【2】Nozzle material: The material of the fan-shaped nozzle is mainly determined according to the chemical characteristics of the bath liquid. For non-corrosive baths, bronze casting or plastic die-casting can be used according to the difficulty of processing; to prevent corrosion, non-metallic materials can be used; for strong corrosive baths such as sulfuric acid, hydrochloric acid, etc., nylon plastic can be used; for phosphating baths The nozzle material of the liquid is generally made of acid-resistant stainless steel, and the nozzle to prevent corrosion can also be directly made of stainless steel or nylon.
【3】Injection angle: The injection angle of the fan nozzle is also a factor that needs to be considered when selecting. The larger the spray angle, the wider the spraying range, but the spraying water flow will be correspondingly weaker. When selecting a fan nozzle, the appropriate spray angle should be selected according to actual needs.
【4】Flow: Flow is one of the important indicators to measure the performance of fan nozzles. The larger the flow rate, the wider the coverage area, but the water pressure and distance of spraying will be reduced accordingly. When selecting a fan nozzle, the appropriate flow rate should be selected according to actual needs.
Selecting the appropriate fan nozzle type based on the above factors can better meet the actual needs and improve the use effect.
