S49CUltrasonic transducerIt is mainly composed of an ultrasonic signal generator and a cleaning tank. The ultrasonic signal generator generates high-frequency oscillation signals, which are converted into high-frequency mechanical oscillations tens of thousands of times per second through a transducer. Ultrasonic waves are formed in the cleaning solution (medium) and radiate and propagate in the cleaning solution in a high-frequency alternating manner of positive and negative pressure, causing countless tiny bubbles to continuously generate and rupture in the cleaning solution. This phenomenon is called“Cavitation effect”When bubbles burst, they can produce sound at high temperature and high pressure, and the cavitation effect generated in the liquid can reach20000order/In seconds or more, a series of explosions occur and release enormous energy, forming a huge shock wave around and continuously impacting the surface of the workpiece, causing the dirt on the surface and gaps of the workpiece to quickly peel off. Even for complex shaped workpieces, as long as they can come into contact with the solution, they can be thoroughly cleaned. Because the volume of each bubble is very small, although their rupture energy is high, they will not produce any significant damage to the workpiece or liquidS49CUltrasonic transducerDestruction and significant temperature rise.

S49CUltrasonic transducercommon problem

1The ultrasonic oscillator is damp and can be checked with a megohmmetertransducerThe basic situation can be determined by checking the insulation resistance value of the connected plug. Generally, it is required that the insulation resistance be greater than5Above megaohms. If the insulation resistance value cannot be reached, it is generally due to moisture damage to the transducer. The transducer as a whole (excluding the spray coated casing) can be placed in an oven for setting100℃Left and right drying3Hour or use a hair dryer to remove moisture until the resistance is normal.

2The oscillator is detached, and our transducer adopts a dual guarantee process of bonding and screw fastening, which usually occurs in this situation. Stainless steel vibration surface perforation, generallytransducerFull load use10There may be perforation of the vibration surface in the year.S49CUltrasonic transducerWhen the oscillator ignites and the ceramic material breaks, it can be inspected with the naked eye and a megohmmeter. Generally, as an emergency measure, individual damaged oscillators can be disconnected without affecting the normal use of other oscillators.
