Description

Ultrasonic vibrator is a kind of device, also called ultrasonic vibrator. The whole connected with transducer and horn is called vibrator.

It is a device that realizes the mutual conversion between electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and is amplified by the front and rear radiation cover blocks that match the acoustic impedance.
Since the horn is a passive device, it does not produce vibration itself, but transmits the input vibration after changing the amplitude, completing the impedance transformation.
Ultrasonic transducers can produce regular vibration under the excitation of electric field, but the amplitude is generally about 10μm. Such amplitude is not enough to directly complete the welding and processing procedures.
Therefore, after the transducer is connected to a reasonably designed horn, the amplitude of the ultrasonic wave can be changed in a large range. As long as the material strength is sufficient, the amplitude can exceed 100 μm.
When the horn performs longitudinal expansion and contraction vibration, the movement directions of the mass points on the left and right sides of a certain cross section in the middle are just opposite, which is equivalent to the existence of a relatively static nodal plane. This nodal surface is called a node, which is also the best fixed point of the vibrator. Deviation from the fixed node of this node will reduce the working efficiency of the vibrator, commonly known as leaky wave.

Commonly used materials

1. Aluminum horns have high sound transmission efficiency, but the material strength is low, easy to crack and threaded holes
2. The steel horn has high strength, but the acoustic impedance is relatively large
3. Titanium alloy horns have good overall performance, but the disadvantages are high price and difficult processing.

Principle

Ultrasonic transducers are widely used. According to the application industries, they are divided into industry, agriculture, transportation, life, medical treatment and military. According to the realized functions, it is divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc.; according to the working environment, it is divided into liquid, gas, biological body, etc.; according to the nature, it is divided into power ultrasonic, detection ultrasonic, ultrasonic imaging, etc. .

The audio frequency electrical signal higher than 28KHZ generated by the ultrasonic generator is converted into the mechanical oscillation of the same frequency through the piezoelectric inverse effect of the transducer, and radiated in the cleaning liquid in the form of ultrasonic longitudinal wave. Due to the alternating positive pressure and negative pressure of the ultrasonic longitudinal wave propagation, countless tiny bubbles of more than 1000 atmospheres are generated and blasted at any time, forming a small local high-pressure bombardment on the surface of the cleaning object, so that the dirt on the surface of the object and the gap can be quickly peeled off. This is the unique "cavitation effect" of ultrasonic cleaning. Definition of ultrasonic vibrator

Ultrasonic vibrator is also called ultrasonic vibrator. In the industry, the whole connection between the transducer and the horn is called the vibrator. It is a device that realizes the mutual conversion between electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and is amplified by the front and rear radiation cover blocks that match the acoustic impedance.

sale the right products instead of the expensive one

Rps-sonic, consisted with a couple of young people who love ultrasonic very much.The founding members of RPS-SONIC have an average degree of Bachelor's degree or above. They have been in the ultrasonic industry for more than 5 years and have rich experience in ultrasound. The company's business philosophy is: Do not blindly promote any product, find the right product for the customer. So before each order, we will confirm all the details, including application details, equipment conditions, equipment specific information.

And we have the Professional import and export company， HangZhou LanBen Trade Co., Ltd, can export to any country wordwide.

Before year 2012, we only sale second branson / dukane / rinco / herrman/telsonic welding equipment , during these twenty year develop, we find, more and more people have problem with the core part of ultrasonic welding equipment -generator and transducer, so we decided to start our business of transducer and generator of our own transducer and generator. Many of the end user meet the transducer problem, they don’t know why transducer broken, and changing the expensive transducer one by one. Actually, one branson /dukane /rinco transducer can use 10~30 year, even the cheapest transducer can use about 5 years. So there must some reasons if your transducer broken in one year. That’s why we want build Rps-sonic, we need to help more end user to know more about transducer , to use ultrasonic equipment better, to save cost when meet problem.

The same to generator, Unreasonable operation may shorter the use-life of ultrasonic generator. So we have to make technical inquiry before operate ultrasonic welding machine. The key point of ultrasonic machine is resonance, only keep every part in resonance can make the system in best work environment.

Till now , we still have a lot of Branson /dukane/ rinco/ herrman telsonic welding machine, so that we can confirm every transducer/generator we made can matching to the original machine.

Of course we can make the transducer/generator replace for Branson /dukane/ rinco/ herrman telsonic welding machine, we can also make transducer/generator for any application of your ultrasonic equipment. We supply OEM service for oversea customers, we already have OEM customer in USA and German.

If you have any problem in ultrasonic area, welcome contact Rps-sonic.
