超声波清洗机设备由三部分组成:超声波发生器(又称超声波电源)、换能器及其它的辅助系统。
Ultrasonic cleaning machine consists of three parts: ultrasonic generator (also known as ultrasonic power), transducer and other auxiliary systems.
超声波发生器将工频电转变成 28KHZ以上的高频电信号,通过电缆输送到换能器上。一般超声波换能器是固定在清洗槽的底板上,清洗槽内装满了液体,当换能器被加上高频电压后,它的压电陶瓷元件在电场作用下便产生纵向振动。
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.
超声波换能器(又称声头)是一种率的换能元件,能将电能转换成强有力的超声波振动,在产生超声波振动时,仿佛是一个小的活塞,振幅很小,约只有几微米。但这个振动加速度很大(几十几千个);槽上具有许多个换能器,施加相同的频率及相位的电能时,就合成了一个巨大的活塞进行往复振动,这种振动的现象,就是平时我们所说的超声波。以下是超声波的组成部分说明
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)换能器:采用特种锆酸钛酸铅PZT压电陶瓷片组成的三明治式的振动头具有效率高、寿命长、不易发生故障的优点。换能器采用特种耐高温、耐振动、高粘度的树脂胶辅以特殊的方法加以固定绝不脱落,且可耐受100℃150℃的高温
(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)超声波发生器(电源):采用功率MOS管超声波发生器,电路,结构完整,辅以灵敏可靠的集成控制系统,保证了超声波清洗机在各种负载下稳定工作。发生器体积小巧,外观新颖,操作十分简便,产品质量及技术水准可与国外同类产品相媲美,一经推出便受到了同行的重视,更得到了广大用户的欢迎。
(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.
各种超声波发生器可独立工作,亦可多组并联使用,以完成大规模清洗工程。维修简单,若有一组发生故障时,不影响其它各组的工作,此点对于生产线来说,更为重要。机箱内装有散热风扇施行强制冷风,确保长期工作的性。
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)加热及温度控制系统:加热器采用铸铝加热片,可耐酸碱,寿命长。加热的目的是将清洗剂加热以增加清洗机的洗涤效果,温度自动控制,可在适当范围内随意调整
(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不锈钢经氩弧焊焊制而成,槽体上设置有排渣检修口、保温隔声层等
(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)槽液循环过滤系统:在该系统中设有过滤器,对槽液进行动态过滤,以维持槽液的清洁度。当工件出槽,经过过滤的液体流经槽体上部的喷淋环节对工件进行一次冲洗,以便冲掉工件出槽,以避免其对下道槽液造成污染。
(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)输送系统:根据被清洗工件的形状、体积、批量等确定超声波清洗机的输送方式及控制方式。典型的输送方式有——悬链、网带、双链、步进、电葫芦、自行葫芦、滚筒、转盘、龙门架、机械手、吊篮、推盘等等。
(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.
