What is an ultrasonic transducer?

The reason why the ultrasonic siening machine can solve the screening problem of strong adsorption, easy agglomeration, high static electricity, high precision, high density, light specific gravity, etc., the key is that the core component of the ultrasonic transducer can achieve high precision and high efficiency screening operation. So what exactly is the ultrasonic transducer? What does it do?

Ultrasonic transducer function

The ultrasonic transducer is an energy conversion device and is the core device of the ultrasonic vibrating screen. The ultrasonic transducer is composed of a central piezoelectric ceramic component, a front and rear metal cover plate, a prestressed screw, an electrode piece and an insulating tube. The ultrasonic transducer on the ultrasonic vibrating screen can make the material have a high frequency and low amplitude force on the screen surface, the contact time between the material and the screen surface becomes shorter, and the vibration frequency becomes larger, so the material blockage can be greatly reduced. In the case of mesh, the screening accuracy can be increased by 1-70% compared with ordinary vibrating screen, and the output can be increased by 0.5-10 times. Ultrasonic transducers and ultrasonic power boxes must be used together. If there are more powders on site, you can place the power box in a clean place on the other side, away from dust pollution.

Ultrasonic transducer working principle

Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies and convert electrical signals into mechanical vibrations by the piezoelectric effect of the material. Under normal circumstances, the ultrasonic generator generates ultrasonic waves first, and the ultrasonic transducer converts the ultrasonic waves into a mechanical vibration, and then the ultrasonic transducer output device and the ultrasonic transducer receiving device can generate ultrasonic waves to make the screen surface Produces supersonic vibrations that are invisible to the naked eye.

The problem to be considered when using an ultrasonic transducer is that it needs to match the input and output, followed by the equipment installation and size. There are many types of ultrasonic machinery on the market. Customers must provide accurate and reliable indicators to ensure that the ultrasonic transducers provided by the manufacturer can be matched with the user's ultrasonic machine to achieve the best performance. Xinxiang Dahan has professional technicians to recommend high-quality ultrasonic transducer equipment according to user needs. The quality is good and the performance is good.
