In order to improve the reliability of piezoelectric ceramics, we usually use metal enclosures to reduce the lateral forces that external mechanical structures may bring to piezoelectric ceramics. However, even using piezoelectric actuators with enclosures, it is necessary to go deep Understand the technical background of piezoelectric ceramic applications and ensure high reliability through proper design and operation.

Even if the structure of the piezoelectric system has proven to be reliable, any seemingly small changes will need to be re-evaluated. In some practical applications, the reliability of piezoelectric ceramics is often discussed under the following two extreme conditions.

Every link in the operation process must be strictly controlled. Through actual testing and evaluation procedures, overload, irrational mechanical structures, mechanical compensations, and correction of inappropriate driving conditions are avoided to achieve high reliability.

Piezoelectric ceramics can output performance based on limited parameters in a short time, but we will not recommend this method. When long-term reliability, long-term work, and high duty cycles are necessary, successful short-term testing of piezoelectric systems does not mean that long-term use is equally safe and reliable. Improper operation will not immediately damage the piezoelectric ceramic, but it will reduce long-term reliability and fail to achieve the expected duty cycle.

The reliability of piezoelectric ceramics is affected by the mechanical structure of the load, the drive control, and the use environment and other conditions; in most applications, due to cost reasons, users often want to use smaller piezoelectric ceramics as possible. However, this makes the pressure Electro-ceramic components have become the weakest link in the system in many mechanical design structures. In addition, piezoelectric ceramics are a relatively complex material and are very sensitive. Improper operation can easily cause damage.

Piezoelectric tube transducer always be used in areas of acoustics or as liquid transmission medium, to transmit axis non-direction ultrasonic signal or incept axis signal, such as surface ship sonar, equal-float cable, underwater speaker, sonobuoy, underwater , passive sonar array, torpedo, oil well detector, oil well dredge , ultrasonic pipe eliminating dirt, etc.

If adding taper model reflecting cover, axis signal will be changed to radial signal, not only improving coupling impedance, but also advancing sensitivity, so that piezoelectric tube transducer also can be used as gas transmission medium.
