亚洲城ca88手机版是以超声波作用于清洗工件,使得附着在工件上的颗粒、油污等随超声波的机械振动而脱落或溶解或乳化等,达到洗净工件的目的。从原理上说,亚洲城ca88手机版中核心部分应该是超声波的作用。
Ultrasonic cleaning equipment uses ultrasonic wave to clean the workpiece, so that the particles and oil stains attached to the workpiece fall off or dissolve or emulsify with the mechanical vibration of ultrasonic wave, so as to achieve the purpose of cleaning the workpiece. In principle, the core part of ultrasonic cleaning equipment should be the function of ultrasonic.
亚洲城ca88手机版中的超声波部分分为两大部件;一个是超声波换能器{或称超声波振头);另一个是超声波发生器,超声波换能器是将超声波发生器提供的电信号转换为机械振动.这篇文章只讨论超声波发生器,不对超声波换能器作讨论.
The ultrasonic part of ultrasonic cleaning equipment is divided into two parts; One is ultrasonic transducer {or ultrasonic vibrator); The other is the ultrasonic generator. The ultrasonic transducer converts the electrical signal provided by the ultrasonic generator into mechanical vibration. This article only discusses the ultrasonic generator, not the ultrasonic transducer
超声波发生器(以下简称发生器)实质是一个功率信号发生器,它产生一定频率的正弦(或类似正弦)信号,超声波发生器的发展与电力电子器件发展密切相关,一般可分为电子管、模拟式晶体管.开关式晶体管这几个阶段,下面分别叙述。
The essence of ultrasonic generator (hereinafter referred to as generator) is a power signal generator, which generates sinusoidal (or similar sinusoidal) signals with a certain frequency. The development of ultrasonic generator is closely related to the development of power electronic devices. Generally, it can be divided into electron tube, analog crystal tube and switching transistor, which are described below.
亚洲城ca88手机版的原理:
Principle of ultrasonic cleaning equipment:
首先由信号发生器来产生一个特定频率的信号,这个信号可以是正弦信号,也可以是脉冲信号,这个特定频率就是换能器的频率,一般在超声波设备中使用到的超声波频率为25KHz、28KHz、35KHz、40KHz;1OOKHz或以上现在尚未大量使用.但随着以后精 密清洗的不断发展。相信使用面会逐步扩大.
Firstly, the signal generator generates a signal with a specific frequency, which can be sinusoidal signal or pulse signal. This specific frequency is the frequency of the transducer. Generally, the ultrasonic frequencies used in ultrasonic equipment are 25kHz, 28kHz, 35kHz and 40KHz; 1ookhz or above has not been widely used yet, but with the continuous development of precision cleaning in the future. It is believed that the application area will gradually expand
功率放大器可有多种形式,如电子管甲类放大器.甲乙类放大器;晶体管甲类或乙类放大器(均属于模拟式):晶体管开关式放大器等,功率一般从50W到5000W不等,由信号发生器产生的频率信号经过功率放大器后需经过阻抗匹配,使得输出的阻抗与换能器相符,推动换能器将电信号转换为机械振动.
There are many forms of power amplifier, such as class a amplifier of electron tube, class a amplifier and class B amplifier; Transistor class A or class B amplifier (both belong to analog type): transistor switching amplifier, etc. the power generally ranges from 50W to 5000W. The frequency signal generated by the signal generator needs impedance matching after passing through the power amplifier to make the output impedance consistent with the transducer, and promote the transducer to convert the electrical signal into mechanical vibration
比较完善的超声波发生器还应有反馈环节,主要提供二个方面的反馈信号:一个是提供输出功率信号,大家知道当发生器的供电电源(电压)发生变化时.发生器的输出功率也会发生变化,这时反映在换能器上就是机械振动忽大忽小,导致清洗效果不稳定.因此需要稳定输出功率,通过功率反馈信号相应调整功率放大器,使得功率放大稳定。
A relatively perfect ultrasonic generator should also have a feedback link, which mainly provides feedback signals in two aspects: one is to provide output power signal. We know that when the power supply (voltage) of the generator changes, the output power of the generator will also change. At this time, it is reflected in the mechanical vibration of the transducer, Therefore, it is necessary to stabilize the output power and adjust the power amplifier accordingly through the power feedback signal to stabilize the power amplification.
