How to choose ultrasonic cleaning transducer
Publish Time: 2019-04-16 Origin: Site
There are two types of transducers for ultrasonic cleaning, one is a magnetostrictive transducer, and the other is a piezoelectric ring transducer. The electrostrictive transducer has a relatively low electroacoustic efficiency. Moreover, metallic nickel materials are expensive and the manufacturing process is complicated, and it is rarely used at present. There is also a magnetostrictive transducer made of ferrite material. Although its electroacoustic efficiency is relatively high, its mechanical strength is low and its electrical power capacity can be withstood. Therefore, it is rarely used in China.
At present, ultrasonic piezoelectric elements are mainly used in China because of the high electro-acoustic conversion efficiency of the transducers, the low cost of raw materials, and the ease of manufacturing different structures to meet different cleaning requirements. Piezoelectric transducers are also available in a variety of shapes such as cylindrical, horn, etc. After comparison, the horn-shaped sandwich piezoelectric transducer is selected as the transducer.
A ultra bath cleaning transducer is a device used for energy conversion and is a device that converts one form of energy into another. In the field of acoustic research, transducers mainly refer to electroacoustic transducers, which can convert between electrical energy and acoustic energy.
