Description :

　　Product Introduction

　　The transducer of an ultrasonic cleaning machine is an energy conversion device that converts the input electrical power into mechanical power (i.e. ultrasonic waves) and transmits it out, while consuming a small portion of the power (less than 10%) on its own. So, the most important consideration when using ultrasonic transducers is the matching with the input and output terminals, followed by mechanical installation and fitting dimensions. There are many types of ultrasonic machines on the market, and customers must provide accurate and reliable indicators to ensure that the transducer products provided by the company can match well with your company's machines and perform well.

　　Due to the wide variety of transducers, this article only provides some transducer parameters.

　　① Resonant frequency: f, unit: KHz

　　This frequency refers to the frequency measured by a frequency generator, millivolt meter, or similar instrument using the transmission line method, or by an impedance characteristic analyzer. Commonly referred to as small signal frequency. The opposite is the operating frequency, which refers to the actual working frequency measured by the customer when the transducer is connected to the driving power supply through a cable and powered on, whether unloaded or loaded. Due to the different matching circuits of customers, the frequency displayed by the same transducer with different driving power sources is different, and such frequency cannot be used as a basis for ordering.

　　② Capacity of transducer: CT, unit: PF

　　The free capacitance of the transducer can generally be measured using a capacitance bridge at frequencies ranging from 400Hz to 1000Hz, or similar instruments such as impedance characteristic analyzers can be used. Simply put, measuring with a regular portable capacitance meter can also meet the requirements.

　　③ Working mode of transducer

　　Due to different processing methods and requirements, the working mode of transducers can be roughly divided into continuous operation (such as lace machines, CD nesting machines, zipper machines, metal welding, etc.) and pulse operation (such as plastic welding machines). Different working modes have different requirements for transducers. Generally speaking, continuous work has almost no pause time, but the working current is not very high. Pulse work is intermittent, with pauses, but the instantaneous current is very high. On average, both states have high power.

　　④ Type and power of transducer

　　The manufacturer of the whole machine may have different regulations on the nominal power of machines for different purposes and purposes, in other words, the nominal power of the same transducer used on different machines may be different. To avoid ambiguity, customers should provide detailed information on the structural types of the transducer, such as column type, inverted horn type, etc., as well as the diameter and number of piezoelectric ceramic chips.

　　⑤ Installation and fitting dimensions

　　Mainly includes the material, surface treatment method, and shape of the amplitude lever. The connection thread between the transducer and the amplitude rod, the connection thread between the amplitude rod and the mold, the diameter, thickness, number and position of notches or screw holes at the flange of the amplitude rod.
