選擇超聲波清洗機(jī)時(shí)，通常是輸出功率。一般來說，超聲波清洗的實(shí)際效果并不一定與輸出功率乘以清洗時(shí)間成正比。

When selecting an ultrasonic cleaner, it is usually the output power. Generally speaking, the actual effect of ultrasonic cleaning is not necessarily proportional to the output power multiplied by the cleaning time.

如果選用的超聲波清洗機(jī)輸出功率比較小，即使是長(zhǎng)時(shí)間使用，也不會(huì)完全污漬，如果選擇的輸出功率較大，雖然可以在短的時(shí)間內(nèi)快速去除污漬，但也會(huì)給被清洗的對(duì)象造成一定的損失。所以選擇超聲波清洗機(jī)，一定要選擇合適的輸出功率。

If the output power of the selected ultrasonic cleaner is relatively small, even if it is used for a long time, it will not completely eliminate the stains. If the output power is large, it can quickly remove the stains in a short time, but it will also cause certain losses to the cleaned objects. Therefore, when choosing the ultrasonic cleaning machine, we must choose the appropriate output power.

當(dāng)輸出功率過大時(shí)，清洗缸底部的振動(dòng)板空化比較嚴(yán)重，而且水點(diǎn)腐蝕也會(huì)擴(kuò)大，如果選擇三氯乙烯等溶劑，可能問題不大，但如果選擇的是水或水溶性清洗液，那么它會(huì)遭受水點(diǎn)侵蝕。

When the output power is too large, the vibration plate at the bottom of the cleaning cylinder is seriously cavitating, and the water point corrosion will also expand. If trichloroethylene and other solvents are selected, it may not be a problem, but if water or water-soluble cleaning fluid is selected, it will suffer from water point corrosion.

總之，在選擇超聲波清洗機(jī)時(shí)，選擇和匹配輸出功率，這樣才能保證清洗效果。

In short, when selecting the ultrasonic cleaning machine, select and match the output power, so as to ensure the cleaning effect.

超聲波清洗機(jī)一直以來清洗效果顯著，操作方便受到大家的青睞。但你可能剛剛聽說過這個(gè)設(shè)備，它是如何工作的，它是如何工作的，沒有任何意義。那么下面小編為大家介紹一下這款超聲波清洗機(jī)的功率和頻率是如何選擇的，一起來看看吧。

The ultrasonic cleaning machine has been widely used for its remarkable cleaning effect and convenient operation. But you may have just heard about this device. How it works, how it works, doesn't make any sense. So the following small series will introduce to you how to choose the power and frequency of this ultrasonic cleaning machine. Let's have a look.

超聲波清洗機(jī)

Ultrasonic cleaning machine

1當(dāng)功率過大時(shí)

1 when the power is too large

超聲清洗機(jī)功率較大時(shí)，聲強(qiáng)變大，空化泡半徑和起始半徑變大，空化強(qiáng)度增強(qiáng)。即聲強(qiáng)越高，空化越強(qiáng)，有利于清洗。但不是功率越大，清洗效果越好，而是正確合理地選擇超聲波功率。

When the power of the ultrasonic cleaning machine is high, the sound intensity increases, the cavitation bubble radius and the initial radius increase, and the cavitation intensity increases. That is, the higher the sound intensity, the stronger the cavitation, which is conducive to cleaning. However, it is not the greater the power, the better the cleaning effect, but the correct and reasonable selection of ultrasonic power.

2小功率偏差

2 small power deviation

聲功率越高，空化效應(yīng)越明顯，產(chǎn)生大量無用氣泡，變大衍射衰減，形成聲屏障。同時(shí)，聲強(qiáng)越高，非線性衰減越大，這將影響被清洗部件遠(yuǎn)離聲源的清洗效果。另外，清洗振動(dòng)板的空化腐蝕更為嚴(yán)重，導(dǎo)致設(shè)備壽命縮短。如果超聲波清洗功率太小，會(huì)影響工件的清洗時(shí)間，清洗時(shí)間會(huì)更長(zhǎng)，或者會(huì)偏離清洗效果。

The higher the sound power, the more obvious the cavitation effect, producing a large number of useless bubbles, increasing the diffraction attenuation and forming a sound barrier. At the same time, the higher the sound intensity, the greater the nonlinear attenuation, which will affect the cleaning effect of the cleaned parts away from the sound source. In addition, the cavitation corrosion of the cleaning vibrating plate is more serious, resulting in the shortening of the service life of the equipment. If the ultrasonic cleaning power is too small, the cleaning time of the workpiece will be affected, the cleaning time will be longer, or the cleaning effect will be deviated.

此，我們?cè)谶x擇超聲波清洗設(shè)備時(shí)，一般工件高度都在30cm以下，那么選用的超聲波清洗設(shè)備在槽高約40cm左右，選擇底部單個(gè)振動(dòng)板，功率保持在每平方厘米0.3~0.5w。如果工件太大，或者每次清洗量太大，我們選擇的水箱高度在40cm以上，一般按功率上升計(jì)算，一般選擇11W/L。

Therefore, when we select ultrasonic cleaning equipment, generally the workpiece height is below 30cm, so the selected ultrasonic cleaning equipment is about 40cm high in the groove, and a single vibrating plate at the bottom is selected, with the power maintained at 0.3~0.5w per square centimeter. If the workpiece is too large or the amount of cleaning each time is too large, the height of the water tank we choose is more than 40cm, which is generally calculated according to the power rise, and 11w/l is generally selected.
