    超聲波清洗機換能器的工作原理
    2019-09-13 16:33:53
    ① 諧振頻率: f, 單位: KHz
    Resonance frequency: F, unit: KHz
    該頻率是指用頻率發生器,毫伏表等通過傳輸線路法測得的頻率,或用阻抗特性分析儀等類似儀器測得的頻率。一般通稱小信號頻率。與它相對的是上機頻率,即客戶將換能器通過電纜連到驅動電源上,通電後空載或有載時測得的實際工作頻率。因客戶的匹配電路各不相同,同樣的換能器配不同的驅動電源表現出來的頻率是不同的,這樣的頻率不能作為訂貨依據。
    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 換能器電容量: CT ,單位:PF
    Transducer capacity: CT, unit: PF
    即換能器自由電容,一般可用電容電橋在400Hz-1000Hz的頻率下測得,也可用阻抗特性分析儀類似儀器。再簡單點,用一般的便攜式電容表測量也可滿足要求。
    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 換能器工作方式
    Transducer working mode
    因加工方式和要求不同,換能器的工作方式大致可分為連續工作(花邊機,CD套機,拉鏈機,金屬焊接等)和脈衝式工作(如塑焊機),不同的工作方式對換能器的要求是不同的。一般而言,連續式工作幾乎沒有停頓時間,但工作電流不是很大,脈衝工作是間歇式的,有停頓,但瞬間電流很大。平均而言,兩種狀態的功率都很大的。
    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 換能器型式和更大功率
    The transducer type and maximum power
    整機廠家可能對於不同用途和目的的機器的標稱功率有不同的規定,換句話說,同樣的換能器用在不同的機器上標稱功率可能是不同的。為避免產生岐義,客戶應詳細說明換能器的結構型式,如柱型、倒喇叭型等,及壓電陶瓷晶片的直徑和片數。
    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 安裝和配合尺寸
    The installation and fitting dimensions
    主要有變幅杆材質,表麵處理方式,形狀。換能器與變幅杆連接螺紋,變幅杆與模具連接螺紋,變幅杆法蘭盤處直徑、厚度、缺口或螺孔數量和位置。
    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.
