The cylinder head is an important part of a diesel engine. Its aqueduct, oil channel, and air channel structure are very complex. The lumen was curved and narrow, and there were many blind spots. Usually sand, graphite, or other stains. Shot peening and sandblasting are also difficult to remove completely. Therefore, in the diesel engine manufacturing industry, the cylinder head cleaning method has been a problem. Before the application of an industrial ultrasonic cleaning machine is mature, the cylinder head of a diesel engine is mainly cleaned by high-pressure jet cleaning and manual immersion cleaning. The high-pressure jet cleaning technology is widely used and mature, some high-pressure jet cleaning machine also has automatic reverse function or water vortex function. In the cylinder head difficult to clean the local location, such as air intake, tappet room, etc., must increase the manual cleaning procedures.
Workers usually use a nylon brush or wire brush repeatedly scrub these parts, while washing with water pipe scrubbing parts to achieve a clean effect. The use of the industrial ultrasonic cleaning machine principle, high-pressure water pump, a large number of nozzles, nozzles to the surface of the cylinder head of the diesel engine wash holes and dissolve the right amount of cleaning agent can be completed without manual cleaning.
The cleaning device of industrial ultrasonic cleaning machine consists of two parts:
Ultrasonic generator (also known as ultrasonic power and transducer). The ultrasonic generator converts the power frequency electric energy into the high-frequency electric signal above 20kHz, and the transducer emits the sound wave. The acoustic energy of the frequency source is converted into mechanical vibration. The ultrasonic wave irradiates the cleaning fluid from the wall of the cleaning tank. Because the liquid in the container is emitted by the ultrasonic wave, the micro-bubbles in the liquid can continue to vibrate under the action of the sound wave.
The ultrasonic vibrator of an industrial ultrasonic cleaner works like a small piston with a small amplitude of only a few microns. But if the vibration acceleration is very large (tens of thousands to thousands of gigabytes), and the grooves are loaded with sensors, the giant piston synthesizes and vibrates back and forth when the same frequency and phase of electrical energy are applied. This vibration causes the base plate of the fixed contactor to be passed to the cleaning fluid, and the vibration is passed to the cleaning fluid, thus the workpiece immersed in water can be cleaned. Industrial ultrasonic cleaning machines generally use cleaning agents. It is a chemical cleaning agent and a water-based cleaning agent. A cleaning medium is chemical action. Ultrasonic cleaning is a physical action. It is a combination of two to thoroughly clean the object.
