How to clean diesel engine cylinder head with industrial ultrasonic cleaner
Cylinder head is an important part of diesel engine. They are generally cast products. It has a very complex structure of waterways, oil passages and air passages. Its lumen is curved, narrow and has many blind spots. Usually sand, graphite powder or other stains. Shot blasting and sandblasting are also difficult to completely remove. Therefore, in diesel engine manufacturing, the method of cleaning cylinder head is always a difficult problem.
The quality of diesel engine cylinder head directly affects the output performance, economy, reliability, vibration, noise and exhaust characteristics of diesel engine. With the development of small and medium-sized diesel engines to the direction of lightweight, high speed, high performance and long life, the requirements for valve CAM design theory and manufacturing technology are becoming higher and higher. The greater the valve CAM inflation coefficient, the greater the intake, the higher the diesel engine's dynamic performance and economy, the lower the exhaust smoke and heat load.
Can industrial ultrasonic cleaner clean the cylinder head of diesel engine? How to use the principle of ultrasonic cleaning machine to clean the diesel engine cylinder head?
The ultrasonic cleaning machine on the market is divided into several categories, including industrial, commercial, medical and household, industrial ultrasonic cleaning machine principle cleaning device by ultrasonic generator (also known as ultrasonic power and transducer) two parts. Ultrasonic generator will power frequency electrical energy into 20 KHZ or more high frequency electrical signals, and by the transducer to send out sound waves. The sound energy of the frequency source is converted into mechanical vibration. The ultrasonic wave irradiates the cleaning fluid in the cleaning tank from the wall of the cleaning tank. Because the liquid in the container is emitted by ultrasonic waves, the microbubbles in the liquid can continue to vibrate in response to sound waves.
When the industrial ultrasonic cleaner ultrasonic vibrator works, it is 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 many sensors are attached to the slot, when the same frequency and phase of electrical energy is applied, huge pistons are synthesized and vibrate back and forth. This vibration makes the base plate of the fixed contacter transferred to the cleaning solution, and the vibration is transferred to the cleaning solution, so that the workpiece immersed in water is cleaned.
Industrial ultrasonic cleaning machine is generally used with cleaning agent, it is a chemical cleaning agent and a water-based cleaning agent, cleaning medium is a kind of chemical action, ultrasonic cleaning is a physical action, is a combination of two kinds of action, thoroughly and thoroughly cleaning objects.
The cleaning of diesel engine cylinder head mainly includes high-pressure jet cleaning and manual immersion cleaning. High pressure jet cleaning technology is widely used and mature at present. Using the principle of industrial ultrasonic cleaning machine, high pressure pump pump water, a large number of nozzles, nozzles will be diesel engine cylinder head surface and hole flushing, dissolve the right amount of cleaning agent to complete the cleaning. Some high pressure jet cleaning machines also have automatic reversal function or water vortex function. Manual cleaning procedures must be added in areas where the cylinder head is difficult to clean, such as air intakes and tappet chambers. Workers usually use nylon brush or wire brush repeatedly scrubbing these parts, while cleaning the scrubbing parts with water pipe, so as to achieve the best cleaning effect.
