Nozzle pressure loss

The pressure loss of the nozzle is determined by the different working methods of the nozzle. For example, among the nozzles of all modes, the linear nozzle has the smallest pressure loss, while the pressure loss of the full cone nozzle is relatively large. The pressure loss of the nozzle is inversely proportional to the impact force of the jet.

In nozzle design, the pressure loss of the nozzle is a parameter we are most concerned about, because if the pressure loss can be reduced through the change of the nozzle structure, it will directly increase the impact force of the nozzle, which is very important for the cleaning industry. When designing the nozzle, we will try to avoid overly complicated internal flow passages, because the complexity of the flow passage means that the liquid is more likely to produce unnecessary turbulence, and turbulence is one of the important reasons for pressure loss.

For example, in the design and manufacture of straight nozzles, we will try to avoid right-angled internal protrusions, and generally use a smooth transition method for processing, which will minimize the resistance of the liquid and reduce the pressure loss of the nozzle.
