What is the sprinkler principle of metal sprinkler

What is the principle of sprinkler irrigation of metal nozzle

(1) startup stage: after the jet shoots out of the deflector through the deflector, rotate 60 ° ~ 120 °, the deflector obtains the reaction force of the jet, so that the rocker arm can obtain kinetic energy to swing outward, rotate around the rocker arm axis, and twist the rocker arm spring to obtain a torque, which is less than the jet reaction torque, so the rocker arm obtains angular velocity and leaves the jet
(2) swing out stage. The inertia force makes the rocker arm continue to rotate, and the opening angle of the straight * rocker arm reaches * large, so as to obtain * large torsional torque. At this time, the angular velocity changes to 0, and the spring potential energy reaches * large, that is, the kinetic energy of the outer swing of the rocker arm is transformed into the elastic potential energy of the spring
(3) bounce phase. Under the action of spring torque, the elastic potential energy of the spring is gradually transformed into the rotational kinetic energy of the rocker arm. The rocker arm begins to swing back, and the angular velocity increases continuously until the rocker arm is about to cut into the jet
(4) in the water entry stage, the rocker arm with * large rotational kinetic energy enters the jet again, and the deflector begins to * accept the water flow first (the water guide plate is not affected by water). The reaction force generated makes the rocker arm kinetic energy increase sharply and the angular velocity become larger and larger
(5) impact stage: under the action of rotating inertia force and tangential additional force of deflector, the rocker arm begins to collide with the nozzle at a large angular velocity, causing the nozzle to rotate 3 ° ~ 5 °. After the collision, the rocker arm completes a complete rotation process. Under the action of friction torque, the nozzle quickly stops. Then continue to repeat the rotation process
