Direct flow phenomenon and treatment of ultrasonic cleaning machine

Direct inlet flow of ultrasonic cleaning machine

The phenomenon of ultrasonic wave flowing along the propagation direction of sound in liquid is called direct inflow. When the sound wave intensity is 0.5w/cm2, the naked eye can see the direct inlet flow, which is perpendicular to the vibrating surface, and the flow rate is about 10cm / s. Through this direct inflow, the micro oil dirt on the surface of the cleaned object is stirred, and the cleaning liquid on the dirt surface also generates convection. The dissolved liquid of dissolved dirt is mixed with the new liquid to accelerate the dissolution speed, which plays a great role in the handling of dirt.

Pretreatment before operation of ultrasonic cleaning machine

Before cleaning, it is advisable to simply clean the dirt on the surface of the parts with a bamboo knife (for example, there will be a lot of dust on the outer surface of the dust cover, and there will be a lot of thick and easy to remove oil sludge on the parts of the cylinder block at the change of the shell curve), so as to prolong the service life of the cleaning fluid.

Ultrasonic can carry out precision cleaning, but its ability to treat mud dirt is weak. Therefore, during pretreatment, yellow mud or thin mud dirt should be removed as much as possible.
