PZT 4 PZT8 50*20*6 mm 30KHz Ultrasonic Cleaner Piezo Ceramic Ring Piezoelectric Welding Transducer Element

Description

The size of this pzt 4 ultrasonic cleaner piezo ceramic ring is 50*20*6 mm. This pzt ring frequency is 30KHz. In fact, pzt-4 rings are also suitable for piezoelectric ultrasonic welding transducer. Tooth cleaner and piezo humidifier use these rings likewise. In addition to pzt-4 material, we also provide PZT-8. Both of them are high power hard piezo material.

This element uses the standard electrode. That is, the positive and negative poles are on different sides. Besides 50*20*6 mm ring, there are many other sizes for choice.

Technical data of our pzt 4 ultrasonic cleaner ceramic ring:

Why pzt 4 piezo ceramic ring can play role in ultrasonic cleaner?

Ultrasonic cleaners have transducers in them. Its core element is the pzt rings. The piezoelectric effect is reversible. That is, the element will deform when a voltage is applied to it. So it can generate ultrasonic waves using the inverse piezoelectric effect of the transducer. Ultrasonic waves in the liquid will produce cavitation and vibration effect.

They can produce tiny air bubbles. These bubbles rapidly expand and rupture in the water. This will create instant high pressure. This will produces powerful shock waves and vortexes. Finally, it will remove the dirt and debris from the surface of items. That is to achieve the purpose of cleaning.

The reasons to choose our piezo ceramic rings pzt-4 50*20*6 mm:

The quality and performance of piezo rings have a direct impact on the cleaning results. If the piezoelectric ceramic quality is poor, it will lead to unstable vibration frequency. Then the cleaning effect of ultrasonic cleaner is poor. If the performance of piezoelectric rings is not good, it will lead to energy loss. The result is lower cleaning efficiency. We have many sizes of pzt rings in stock. In addition to 50*20*6 mm, there are dozens of sizes. Our pzt 4 ultrasonic cleaner ceramic ring has many advantages.

① Low dielectric loss factor: Tgδ is only 0.3%. At the same time, the mechanical quality factor is high: they have a Qm value of 1000. Therefore, our pzt 4 ceramic rings are ideally suited for high-frequency application e.g. ultrasonic cleaners.

This makes the cleaner highly efficient: ultrasound can quickly strip the surface of dirty objects. It can also penetrate deeply into the tiny pores and uneven surface areas of the objects. Ultimately achieve comprehensive cleaning.

② Good stability: we sinter the pzt-4 50*20*6 mm piezo ceramic rings at high temperature. It has good thermal and chemical stability. And the internal structure is dense. Therefore, it has high reliability and lifetime.

③ Custom service: Piezoelectric rings need to be used together with circuit boards. If need the circuit board, we can also provide it. Moreover, we also produce the transducers for ultrasonic cleaners.

Can you advise what the voltage of this pzt-4 50*20*6 mm piezo ceramic ring is?

Here the ultrasonic cleaner ceramic ring uses the PZT-4 material. And the vibration mode is thickness direction. In order to know the static voltage, we must to know the calculation formula. Piezo ring voltage = V = (4*g33*F3*h)/Π(OD² – ID²).

g33: Piezoelectric constant in “10-3 Vm/N”;
F3: Force in “N”;
h: height in “mm”;
Π: which is π, 3.14;
OD. outer diameter, in “mm”;
ID: inner diameter, in “mm”;

According to our pzt ceramic material performance table, we can know that g33 is 24 (10^-3 Vm/N). Assuming a force of 25 N, then V ≈ [4*24 (10^-3 Vm/N)*25N*6mm]/[3.14*(50² – 20²)] ≈ [4*24 (10^-3 V*1000mm/N)*25N*6mm]/[3.14*(50² – 20²)]  ≈ 2.1827 V.

So we can know the voltage of this pzt-4 50*20*6 mm ultrasonic cleaner piezo ceramic ring is 2.1827V.
