1.看超聲頻率

1. Check the ultrasound frequency

市面上的超聲波清洗機(jī)，大多數(shù)頻率在40~50kHz左右，這個(gè)頻率階段是非常中庸的頻段，契合絕大多數(shù)場景的運(yùn)用。可是正式因?yàn)檫@個(gè)頻段運(yùn)用非常多，導(dǎo)致振子（即換能器）的質(zhì)量紛歧。而具有高頻（100kHz左右）或許低頻（25kHz）頻段的超聲波清洗機(jī)，其振子質(zhì)量相對(duì)較好，尤其某些雙頻的機(jī)器，其振子必定優(yōu)于單頻的機(jī)器。所以在選購時(shí)，條件答應(yīng)的話，能夠優(yōu)先挑選雙頻的機(jī)器，然后根據(jù)被清洗物挑選高頻仍是低頻。

Most ultrasonic cleaning machines on the market operate at frequencies around 40-50 kHz, which is the most moderate frequency range and suitable for the vast majority of applications. However, due to the frequent use of this frequency band, the quality of the oscillator (i.e. transducer) varies. Ultrasonic cleaning machines with high-frequency (around 100kHz) or low-frequency (25kHz) frequency bands have relatively good oscillator quality, especially for some dual frequency machines, whose oscillators are definitely better than single frequency machines. So when making a purchase, if conditions permit, priority can be given to choosing a dual frequency machine, and then selecting high frequency or low frequency based on the item being cleaned.

2.看功率

2. Check the power

功率越高，清洗效果越好，這是毋庸置疑的?？墒沁^高的功率會(huì)對(duì)被清洗物有所腐蝕，所以功率太大了也不好。那么應(yīng)該怎樣挑選呢？其實(shí)部分廠家也考慮到了這一點(diǎn)，所有，有的清洗機(jī)設(shè)備是能夠自行調(diào)整超聲功率的，1%~99%可調(diào)。帶有功率可調(diào)功用的設(shè)備，條件答應(yīng)的話盡量往大功率的買。

The higher the power, the better the cleaning effect, there is no doubt about it. However, excessive power can corrode the object being cleaned, so having too much power is also not good. So how should we choose? In fact, some manufacturers have also taken this into consideration. Some cleaning equipment can adjust the ultrasonic power by themselves, with a range of 1% to 99% adjustable. If conditions permit, try to buy high-power equipment with adjustable power function.

3.聽聲響

3. Listen to the sound

聽聲響，是指聽設(shè)備作業(yè)時(shí)的聲響。理論上來說，超聲波是人耳聽不到的聲響，可是在實(shí)踐中，超聲波清洗機(jī)是會(huì)發(fā)出必定的噪音的，這是由于各種原因造成的。當(dāng)兩款設(shè)備，原料基本相同，功率和頻率也相一起，哪一個(gè)的噪音小，闡明質(zhì)量比較好。原因是：

Listening to sound refers to listening to the sound of equipment during operation. In theory, ultrasound is a sound that the human ear cannot hear, but in practice, ultrasonic cleaning machines will emit certain noise due to various reasons. When two devices have similar raw materials, power, and frequency, which one has lower noise indicates better quality. as a result of:

振子作業(yè)時(shí)不是100%處于超聲頻段的，好的振子處在超聲頻段的時(shí)刻較多，噪音就小。

When the oscillator is working, it is not 100% in the ultrasonic frequency band. Good oscillators spend more time in the ultrasonic frequency band, resulting in less noise.

噪音小，闡明資料之間的密封性好，也就是制作工藝要求比較高，這樣的設(shè)備愈加耐用。

The equipment has low noise and good sealing between the data, which means that the production process requirements are relatively high, making it more durable.
