Description

technical field [0001] The present invention relates to a self-rotating sprinkler head with magnetoelectric eddy current resistance and speed regulation for a pre-mixed ship derusting machine. Specifically, it can generate eddy current through the rotation of a strong conductor in a strong magnetic field, and convert the rotational energy into electrical energy to generate resistance. A device for adjusting the rotation speed of the self-rotating nozzle body. Background technique [0002] At present, most of the self-rotating nozzles of the pre-mixing ship rust remover are greatly affected by the supply pressure and the diameter of the nozzle during the self-selection process: the pressure is low, the nozzle diameter is small, the nozzle cannot rotate automatically, the pressure is high, the nozzle diameter is large At this time, the rotating speed of the nozzle is very fast, reaching 6500rpm. These two states are not suitable for normal work; engineers often design the self...

Problems solved by technology

[0002] At present, most of the self-rotating nozzles of the pre-mixing ship rust remover are greatly affected by the supply pressure and the diameter of the nozzle during the self-selection process: the pressure is low, the nozzle diameter is small, the nozzle cannot rotate automatically, the pressure is high, the nozzle diameter is large At this time, the rotating speed of the nozzle is very fast, reaching 6500rpm, and these two states are not suitable for normal work; engineers often design the self-rotating nozzle as two nozzles, and the radial distance and axial angle between the two nozzles should be as large as possible. It is also enough to rotate automatically when the pressure fluctuation is low, so that when the pressure of the system is high, the rotation speed of the self-rotating nozzle body will be very fast, close to 7000rpm, which is not the ideal speed for rust removal work; however, there is no such thing yet A device that can keep the spinner spinning while the pressure fluctuations are low, and can be adjusted to reduce the spin speed when the pressure is high, solves this problem
