Basic Introduction：

vibration meterAlso known as a seismometer vibration analyzer or seismometer pen, it is designed using the piezoelectric effect of quartz crystals and artificially polarized ceramics (PZT). It is widely used in fields such as mechanical manufacturing, electricity, and metallurgical vehicles.

To achieve modernization of equipment management, factories should actively promote equipment management methods and adopt equipment maintenance techniques based on equipment status monitoring. Equipment status monitoring and fault diagnosis technology are prerequisites for preventive maintenance of equipment. Especially in heavy industry enterprises, there is a strong demand for work continuity and high safety and reliability, which can be achieved through condition monitoring.

Principle of vibration meter:

A vibrometer, also known as a seismometer, vibration analyzer, or seismometer pen, is designed using the piezoelectric effect of quartz crystals and artificially polarized ceramics (PZT). When quartz crystals or artificially polarized ceramics are subjected to mechanical stress, charges are generated on their surfaces. Using a piezoelectric accelerometer, the vibration signal is converted into an electrical signal. By processing and analyzing the input signal, the acceleration, velocity, and displacement values of the vibration are displayed, and the corresponding measurement values can be printed out using a printer. The technical performance of this instrument meets the requirements of standard 2954 and the Chinese national standard GB/T13824 for the sine excitation method vibration standard in vibration intensity measuring instruments. It is widely used in fields such as mechanical manufacturing, electricity, and metallurgical vehicles.

Key Features:

Vibration testing is an important means of diagnosing equipment status and faults, and the use of handheld vibration meters has improved production safety, quality, and efficiency. Therefore, the research on handheld vibration meters is of great significance and practical value. This article analyzes the development of vibration testers and the development status of vibration testing systems at home and abroad. In response to the limitations of single system functions or high prices of vibration testers, combined with the application of microcontrollers, we focus on developing handheld vibration testers with high accuracy, small size, strong functionality, strong anti-interference, and low cost. The main work carried out includes the following aspects: 1. Based on the overall design scheme of the handheld vibration meter, a circuit block diagram was provided and the Pro99SE software was used to layout the PCB specific circuit, and important parameters of the circuit were analyzed and calculated. Various anti-interference measures have been taken in both hardware and software to ensure measurement accuracy and improve instrument reliability. 2. Fully understand the vibration measurement system, and based on the existing piezoelectric acceleration sensor and charge amplifier vibration measurement system, design an integrated handheld vibration meter with built-in micro dual charge amplifier and frequency compensation circuit. 3. Adopting the ZOOMFFT algorithm in data processing has improved the accuracy of measurements; The principle of embedded system is adopted to create a data file storage system, which improves the reading speed and saves the RAM space of the microcontroller; The communication adopts USB interface, which improves the speed of data transmission and provides a good foundation for secondary development.

8. Suitable for vibration and temperature measurement of various types of machinery.

Measurement method determination:

1. The application of vibration meters for equipment status detection, although not the only basis for determining the equipment overhaul cycle, is essential as a reference condition. Due to the low speed of equipment such as water pumps and fans, the harm caused by vibration is not the only one. For example, sometimes there are no problems detected with a vibration meter, but the impeller is severely corroded and requires major repairs. Therefore, the determination of the equipment overhaul cycle should be comprehensively considered from various aspects such as the results of vibration meter testing, accumulated operating hours of equipment, and efficiency.

2. It is also necessary to use a vibration meter for inspection as a means of acceptance after major equipment repairs. It should be pointed out that due to the varying degrees of equipment age, there is no unified regulation on the inspection values for its acceptance. The inspection values before the major overhaul of the accepted pump set should be used as the basis, and the inspection values after the overhaul should also be based on the inspection values before the major overhaul of the accepted pump set. The repaired values should be lower than the pre repair values. In addition, the application of a vibration meter can also detect installation problems with the pump unit (including poor alignment, loose anchor bolts during long-term operation), as well as pump cavitation phenomena.

In short, the use of vibration meters in conjunction with other detection instruments is beneficial for analyzing the operating status of the equipment. When used in conjunction with instruments such as vibration meters, oil quality analyzers, and motor fault detectors, it can more accurately determine the operation of the equipment.
