超聲波清洗設備三部分結構組成

作者：admin來源：http://www.hailaozhen.net.cn/時間：2020-11-12

超聲波清洗機設備由三部分組成：超聲波發(fā)生器（又稱超聲波電源）、換能器及其它的輔助系統(tǒng)。

Ultrasonic cleaning machine consists of three parts: ultrasonic generator (also known as ultrasonic power), transducer and other auxiliary systems.

超聲波發(fā)生器將工頻電轉變成 28KHZ以上的高頻電信號，通過電纜輸送到換能器上。一般超聲波換能器是固定在清洗槽的底板上，清洗槽內裝滿了液體，當換能器被加上高頻電壓后，它的壓電陶瓷元件在電場作用下便產生縱向振動。

The ultrasonic generator converts the power frequency electric signal into high frequency electric signal above 28kHz, which is transmitted to the transducer through the cable. Generally, ultrasonic transducer is fixed on the bottom plate of the cleaning tank, which is filled with liquid. When the transducer is applied with high frequency voltage, its piezoelectric ceramic components will produce longitudinal vibration under the action of electric field.

超聲波換能器（又稱聲頭）是一種高效率的換能元件，能將電能轉換成強有力的超聲波振動，在產生超聲波振動時，仿佛是一個小的活塞，振幅很小，約只有幾微米。但這個振動加速度很大（幾十至幾千個）；槽上具有許多個換能器，施加相同的頻率及相位的電能時，就合成了一個巨大的活塞進行往復振動，這種振動的現(xiàn)象，就是平時我們所說的超聲波。以下是超聲波的組成部分說明

Ultrasonic transducer (also known as sound head) is a kind of high-efficiency energy conversion element, which can convert electric energy into strong ultrasonic vibration. When ultrasonic vibration is generated, it seems to be a small piston with a small amplitude of only a few microns. But this vibration acceleration is very large (tens to thousands); there are many transducers on the groove. When the same frequency and phase electric energy are applied, a huge piston is synthesized for reciprocating vibration. This vibration phenomenon is what we usually call ultrasonic wave. The following is a description of the components of ultrasound

(1)換能器：采用特種鋯酸鈦酸鉛PZT壓電陶瓷片組成的三明治式的振動頭具有效率高、壽命長、不易發(fā)生故障的優(yōu)點。換能器采用特種耐高溫、耐振動、高粘度的樹脂膠輔以特殊的方法加以固定絕不脫落，且可耐受100℃150℃的高溫

(1) Transducer: sandwich vibrator composed of special lead zirconate titanate PZT piezoelectric ceramic plate has the advantages of high efficiency, long service life and no failure. The transducer is fixed by special resin glue with high temperature resistance, vibration resistance and high viscosity, and can withstand the high temperature of 100 ℃ and 150 ℃

(2)超聲波發(fā)生器（電源）：采用功率MOS管超聲波發(fā)生器，電路，結構完整，輔以靈敏可靠的集成控制系統(tǒng)，保證了超聲波清洗機在各種負載下穩(wěn)定工作。發(fā)生器體積小巧，外觀新穎，操作十分簡便，產品質量及技術水準可與國外同類產品相媲美，一經推出便受到了同行的重視，更得到了廣大用戶的歡迎。

(2) Ultrasonic generator (power supply): the power MOS tube ultrasonic generator is adopted. The circuit is advanced, the structure is complete, and the sensitive and reliable integrated control system is used to ensure the stable operation of the ultrasonic cleaning machine under various loads. The generator is small in size, novel in appearance, and easy to operate. The quality and technical level of the generator are comparable to those of similar products abroad. Once launched, it has been paid attention to by peers and welcomed by the majority of users.

各種超聲波發(fā)生器可獨立工作，亦可多組并聯(lián)使用，以完成大規(guī)模清洗工程。維修簡單，若有一組發(fā)生故障時，不影響其它各組的工作，此點對于生產線來說，更為重要。機箱內裝有散熱風扇施行強制冷風，確保長期工作的安全性。

Various ultrasonic generators can work independently or in parallel to complete large-scale cleaning projects. The maintenance is simple. If one group fails, the work of other groups will not be affected, which is more important for the production line. The cooling fan is installed in the cabinet to implement forced cold air to ensure the safety of long-term operation.

(3)加熱及溫度控制系統(tǒng)：加熱器采用鑄鋁加熱片，可耐酸堿，壽命長。加熱的目的是將清洗劑加熱以增加清洗機的洗滌效果，溫度自動控制，可在適當范圍內隨意調整

(3) Heating and temperature control system: the heater adopts cast aluminum heating plate, which can resist acid and alkali and has long service life. The purpose of heating is to heat the cleaning agent to increase the washing effect of the cleaning machine. The temperature is automatically controlled and can be adjusted at will within an appropriate range

(4) 清洗槽：清洗槽采用SU304不銹鋼經氬弧焊焊制而成，槽體上設置有排渣檢修口、保溫隔聲層等

(4) Cleaning tank: the cleaning tank is made of su304 stainless steel by argon arc welding, and the tank body is provided with slag discharge access, thermal insulation and sound insulation layer

（5)槽液循環(huán)過濾系統(tǒng)：在該系統(tǒng)中設有過濾器，對槽液進行動態(tài)過濾，以維持槽液的清潔度。當工件出槽，經過過濾的液體流經槽體上部的噴淋環(huán)節(jié)對工件進行一次沖洗，以便沖掉工件出槽，以避免其對下道槽液造成污染。

(5) Tank liquid circulation filtration system: a filter is set in the system to dynamically filter the tank liquid to maintain the cleanliness of the tank liquid. When the workpiece is out of the tank, the filtered liquid flows through the spray link on the upper part of the tank body to wash the workpiece once, so as to flush the workpiece out of the groove, so as to avoid the contamination of the next channel liquid.

(6)輸送系統(tǒng)：根據(jù)被清洗工件的形狀、體積、批量等確定超聲波清洗機的輸送方式及控制方式。典型的輸送方式有——懸鏈、網(wǎng)帶、雙鏈、步進、電葫蘆、自行葫蘆、滾筒、轉盤、龍門架、機械手、吊籃、推盤等等。

(6) Conveying system: determine the conveying mode and control mode of ultrasonic cleaning machine according to the shape, volume and batch size of the workpiece to be cleaned. The typical conveying methods are suspension chain, mesh belt, double chain, stepping, electric hoist, self-propelled hoist, drum, turntable, gantry, manipulator, basket, pusher, etc.

(7)噴淋漂洗系統(tǒng)：根據(jù)被清洗工件的表面狀況，有的清洗機配備噴淋漂洗工序，將超聲波清洗和噴淋清洗有機地結合起來。(8烘干系統(tǒng)：根據(jù)被清洗工件的狀況，有的清洗機配備烘干系統(tǒng)，烘干系統(tǒng)主要由加熱器、風機、吹風噴嘴等組成，溫度自動控制。

(7) Spray rinsing system: according to the surface condition of the workpiece to be cleaned, some cleaning machines are equipped with spray rinsing process, which organically combines ultrasonic cleaning and spray cleaning. (8) drying system: according to the condition of the workpiece to be cleaned, some cleaning machines are equipped with drying system. The drying system is mainly composed of heater, fan and blowing nozzle, with automatic temperature control.
