選一台合適的扶老二官网下载IOS，遠比想象中複雜。選型失誤不僅浪費投資，更可能影響產品質量和生產效率。

Choosing a suitable ultrasonic cleaning machine is far more complex than imagined. Incorrect selection not only wastes investment, but may also affect product quality and production efficiency.

第一個坑：頻率選錯。 頻率直接決定清洗效果。清洗大型金屬件、去除厚重油汙和鏽蝕，低頻（20-28kHz）是優選。清洗精密零件、電子元器件、光學鏡片，高頻（80kHz以上）更合適。如果工件種類多樣，雙頻扶老二官网下载IOS是折中選擇——低頻掃除頑固汙漬，高頻處理精細表麵。

The first pitfall: selecting the wrong frequency. The frequency directly determines the cleaning effect. Cleaning large metal parts, removing heavy oil stains and rust, low frequency (20-28kHz) is preferred. High frequency (above 80kHz) is more suitable for cleaning precision parts, electronic components, and optical lenses. If there are various types of workpieces, a dual frequency ultrasonic cleaning machine is a compromise choice - low-frequency cleaning for stubborn stains and high-frequency processing for fine surfaces.

第二個坑：功率不足或過大。 功率不足，空化效應微弱，清洗不有效。功率過大，對於精密工件可能造成表麵損傷。功率選擇需綜合考慮槽體容積、清洗液類型、工件材質和汙染物種類。一般原則是：單位容積功率密度在0.3-0.5W/cm?之間較為合理。

The second pitfall: insufficient or excessive power. Insufficient power, weak cavitation effect, and incomplete cleaning. Excessive power may cause surface damage to precision workpieces. The selection of power should comprehensively consider the tank volume, type of cleaning solution, workpiece material, and type of pollutants. The general principle is that the power density per unit volume is between 0.3-0.5W/cm? It is more reasonable between them.

第三個坑：溫度設置不當。 超聲波清洗並非“越熱越好”。大多數水基清洗劑在50-60℃時活性非常佳。溫度過低，清洗劑活性不足；溫度過高，空化效應反而減弱（液體蒸氣壓升高，氣泡破滅強度降低）。夏季可設定50-55℃，冬季可適當提高至60-65℃。

The third pitfall: Improper temperature setting. Ultrasonic cleaning is not necessarily 'the hotter the better'. Most water-based cleaning agents have the best activity at 50-60 ℃. Low temperature and insufficient activity of cleaning agents; When the temperature is too high, the cavitation effect actually weakens (the liquid vapor pressure increases, and the strength of bubble bursting decreases). In summer, the temperature can be set at 50-55 ℃, and in winter, it can be appropriately increased to 60-65 ℃.

第四個坑：忽視脫氣環節。 新注入的清洗液中溶解有大量氣體，這些氣體會吸收超聲波能量，降低空化效應強度。因此，新液注入後應先運行超聲波進行脫氣處理（通常10-15分鍾），待氣泡充分排出後再放入工件。許多操作者忽略這一步，導致清洗效果大打折扣。

The fourth pitfall: Neglecting the degassing process. A large amount of gas is dissolved in the newly injected cleaning solution, which absorbs ultrasonic energy and reduces the intensity of cavitation effect. Therefore, after injecting the new liquid, ultrasonic treatment should be run first for degassing (usually 10-15 minutes), and the workpiece should be placed after the bubbles are fully discharged. Many operators overlook this step, resulting in a significant reduction in cleaning effectiveness.

第五個坑：清洗液管理混亂。 清洗液是消耗品，需要定期更換和過濾。長時間不清洗更換，清洗液中懸浮的汙垢顆粒會重新附著在工件表麵，造成二次汙染。建議配備循環過濾係統，在清洗過程中持續過濾清洗液，延長使用壽命。同時注意液麵高度——液麵過低可能損壞換能器，液麵過高則影響空化效應的傳播效率。

The fifth pit: chaotic management of cleaning solution. Cleaning solution is a consumable that requires regular replacement and filtration. If not cleaned or replaced for a long time, the suspended dirt particles in the cleaning solution will reattach to the surface of the workpiece, causing secondary pollution. It is recommended to equip a circulating filtration system to continuously filter the cleaning solution during the cleaning process and extend its service life. At the same time, pay attention to the liquid level - a low liquid level may damage the transducer, while a high liquid level can affect the propagation efficiency of cavitation effects.

日常維護同樣不可忽視。定期檢查換能器是否有脫落或鬆動。清洗槽底部如有沉積物應及時清理。發生器應保持通風良好、避免過載運行。

Daily maintenance cannot be ignored either. Regularly check whether the transducer is detached or loose. If there is sediment at the bottom of the cleaning tank, it should be cleaned in a timely manner. The generator should maintain good ventilation and avoid overload operation.
