In the face of the problem of unsatisfactory results of acoustic leak detection equipment in plastic pipeline pipeline leak detector, we really need to take a series of measures to improve and optimize the existing detection means. Plastic pipe and metal pipe in the acoustic conduction characteristics of the significant differences between the traditional acoustic leak detection methods in plastic pipe is difficult to play the best results.
First of all, we need to face up to the sound transmission characteristics of plastic pipes and metal pipes are different. Plastic pipe pipeline leak detector acoustic conductivity is poor, the sound of water leakage in the pipeline internal propagation to the surface of the ability to be limited, and the sound frequency is mostly low-frequency. Therefore, to address this problem, we can consider the following aspects of improvement:
First, research and development of specialized instruments
For the acoustic characteristics of plastic pipes, we should develop special acoustic pipeline leak detector. these instruments should be equipped with high sensitivity probes, such as improved hydrophones, to more accurately capture the low-frequency leakage sound on plastic pipes. At the same time, the filter settings of the instrument should be adjusted accordingly to ensure that a wider range of sound frequencies can be covered.
Second, accurate measurement of sound transmission velocity
For plastic pipes, knowing the exact sound transmission velocity is critical to improving detection accuracy. Different types of plastic pipes may have different sound transmission velocities, so in the actual inspection, we should ensure that we use the sound transmission velocity data that matches the local plastic pipe type. This will help us to locate leaks more accurately.
III. Innovative Ground Listening Techniques
In addition to directly detecting the sound of the pipe itself, we can also try to use pipeline leak detector ground listening technology to assist detection. By using the pipeline leak detector on the ground to capture the sound propagating from the leak to the ground, we can get a more comprehensive understanding of the leak. This method is particularly suitable for those occasions where it is difficult to gain direct access to the pipeline.
Upgrading personnel skills
In addition to technical improvements, we should also focus on improving the professional skills of leak detection personnel. Through training to make them familiar with the operation methods and techniques of the new leak detector, as well as mastering the acoustic properties of plastic pipes, so as to improve the accuracy and efficiency of detection.
In conclusion, we need to improve and optimize the leakage detection of plastic pipes in many ways. Through the comprehensive application of research and development of special instruments, precise measurement of sound transmission speed, innovative ground listening technology and upgrading of personnel skills, we can improve the accuracy and efficiency of water leakage detection of plastic pipes and provide a strong guarantee for the healthy operation of water supply and drainage systems.
