The cylinder head is an important part of the diesel engine. Its waterway, oilway and airway structure is very complicated. Its pipe lumen is curved and narrow, with many blind spots. It is usually sand, graphite powder or other stains. It is also difficult to remove completely by shot blasting and sand blasting. Therefore, in the diesel engine manufacturing industry, the cleaning method of the cylinder head has been a difficult problem.
Before the application of industrial ultrasonic cleaning machine is mature, diesel engine cylinder head cleaning mainly using high-pressure jet cleaning and manual immersion cleaning. And high-pressure jet cleaning technology is widely used and mature, some high-pressure jet cleaning machine also has automatic reversal function or water vortex function. In the cylinder head is difficult to clean the local location, such as air inlet, tappet chamber, etc., must increase the manual cleaning procedures. Workers usually use nylon brushes or wire brushes to repeatedly scrub these parts, while rinsing scrubbing parts with a water hose to achieve clean results. And the use of industrial ultrasonic cleaning machine principle, high-pressure water pump pumping water, a large number of nozzles, nozzles to the surface of the diesel cylinder head rinse holes and dissolve the appropriate amount of detergent can be completed without manual cleaning.
Industrial ultrasonic cleaning machine cleaning principle of diesel engine cylinder head.
Industrial ultrasonic cleaning machine cleaning device consists of two parts: ultrasonic generator (also known as ultrasonic power and transducer). Ultrasonic generator will work frequency electrical energy into a high-frequency electrical signal above 20kHz, the transducer emits sound waves. Frequency source of acoustic energy into mechanical vibration. Ultrasonic waves from the wall of the cleaning tank irradiate the cleaning liquid in the cleaning tank. As the liquid in the container is issued by ultrasonic waves, the micro bubbles in the liquid can continue to vibrate under the action of sound waves.
Industrial ultrasonic cleaning machine ultrasonic vibrator work like a small piston, the amplitude is very small, only a few microns. However, if this vibration acceleration is very large (tens of thousands to thousands of g) and the groove is fitted with many sensors, when the same frequency and phase of electrical energy is applied, the huge piston will synthesize and vibrate back and forth. This vibration makes the bottom plate of the fixed contactor to transfer the vibration to the cleaning fluid, which can clean the workpiece immersed in water.
Industrial ultrasonic cleaning machine generally use cleaning agent. It is a chemical cleaning agent and a water-based cleaning agent. Cleaning medium is a chemical action. Ultrasonic cleaning is a physical action. It is a combination of the two to thoroughly clean the object.
