    超声波清洗机换能器的工作原理
    2016-6-2 16:33:53
    ① 谐振频率: f, 单位: KHz
    Resonance frequency: F, unit: KHz
    该频率是指用频率发生器,毫伏表等通过传输线路法测得的频率,或用阻抗特性分析仪等类似仪器测得的频率。一般通称小信号频率。与它相对的是上机频率,即客户将换能器通过电缆连到驱动电源上,通电后空载或有载时测得的实际工作频率。因客户的匹配电路各不相同,同样的换能器配不同的驱动电源表现出来的频率是不同的,这样的频率不能作为订货依据。
    The frequency refers to the frequency generator, millivolt table through a transmission line method measuring the frequency, or frequency measured by impedance analyzer and other similar instruments. Commonly known as the small signal frequency. And it is relative to the frequency of the machine, that is, the customer will be connected to the transducer through the cable to the power supply, the power of the actual operating frequency after power supply or load. Because the customer's matching circuit is not the same, the same transducer with different driving power supply performance is different, so the frequency can not be used as a basis for ordering.
    ② 换能器电容量: CT ,单位:PF
    Transducer capacity: CT, unit: PF
    即换能器自由电容,一般可用电容电桥在400Hz-1000Hz的频率下测得,也可用阻抗特性分析仪类似仪器。再简单点,用一般的便携式电容表测量也可满足要求。
    That is the transducer free capacitance, generally available capacitance bridge in the frequency of 400Hz-1000Hz measured, also can be used as an instrument of impedance characteristics analyzer. Then simply point, with the general measurement of the portable capacitance table can also meet the requirements.
    ③ 换能器工作方式
    Transducer working mode
    因加工方式和要求不同,换能器的工作方式大致可分为连续工作(花边机,CD套机,拉链机,金属焊接等)和脉冲式工作(如塑焊机),不同的工作方式对换能器的要求是不同的。一般而言,连续式工作几乎没有停顿时间,但工作电流不是很大,脉冲工作是间歇式的,有停顿,但瞬间电流很大。平均而言,两种状态的功率都很大的。
    Because of the different processing methods and requirements, transducer can be roughly divided into continuous duty (lace machine, CD kit, zipper machine, metal welding, etc.) and pulse type of work (such as plastic welder) and different ways of working exchange to requirements of the device is different. In general, the continuous work of almost no pause time, but the work is not very large current, pulse work is intermittent, there is a pause, but the current is very large. On average, the power of the two states is very large.
    ④ 换能器型式和最大功率
    The transducer type and maximum power
    整机厂家可能对于不同用途和目的的机器的标称功率有不同的规定,换句话说,同样的换能器用在不同的机器上标称功率可能是不同的。为避免产生岐义,客户应详细说明换能器的结构型式,如柱型、倒喇叭型等,及压电陶瓷晶片的直径和片数。
    The machine manufacturer may have different requirements for the nominal power of the machine for different purposes and purposes, in other words, the same transducer may be different from the nominal power on different machines. To avoid ambiguity, the customer should be detailed description of the structure of the transducer type, such as column type, inverted horn type, and pressure electric ceramic wafer diameter and number of pieces.
    ⑤ 安装和配合尺寸
    The installation and fitting dimensions
    主要有变幅杆材质,表面处理方式,形状。换能器与变幅杆连接螺纹,变幅杆与模具连接螺纹,变幅杆法兰盘处直径、厚度、缺口或螺孔数量和位置。
    Mainly has the horn material, the surface treatment method, the shape. Transducer and horn connection thread, horn and mold connecting thread, flange of horn disc diameter, thickness, gap or hole number and location.
