Nozzles at different pressures, the nozzle injection angle will have different changes:
When the pressure is low, the angle will become smaller, the impact intensity is relatively smaller, the pressure gradually increases, the spray angle will gradually increase, the impact of cleaning force will gradually increase. Different materials have different pressure to withstand, so the general nozzle will be required to use under standard pressure, when the nozzle wear, on the one hand will change the nozzle flow, but also affect the standard jet angle, flow increases, pressure Will be reduced, the angle will be reduced accordingly, wear the nozzle will change the spray direction, the use of efficiency greatly reduced.
