Today, the problem should be paid attention to when using the Popular Pipeline detector when using. If there is a feeling of this feeling about the underground pipeline detector, Xiaobian has already made a simple introduction to everyone, here is not described here.
Today, the problem should be paid attention to when using the Popular Pipeline detector when using. If you have friends who are interested in this, you can read this article carefully. Underground pipeline detector is an essential tool for construction, acceptance and ground census construction, acceptance and ground census.
Since the Underground Underground Pipeline Probe Detector Production in China, its excellent performance and flexible detection methods have their own users in power, telecommunications, water supply, heat, gas, oil, chemical, urban public utility and other fields. Underground Underground Pipeline detector plays a positive role in improving the pipe management level of my country's related industries. The underground pipeline detector consists of transmitters, receivers and accessories, used for precise positioning, depth measurement and long distance tracking, as well as measurements and search of pipe insulation fault points for underground pipelines.
Underground pipeline detectors use multi-coil electromagnetic technology to improve the accuracy of pipeline positioning depth and identification of target pipes, which can accurately track and locate target pipes in the pipe-intensive region. The pipeline leakage current can be received separately from the A-strand two pin, and the signal size displayed by the receiver is the difference value of the two-needle reception signal. When the difference between the two needles is zero, it indicates that the A cradle is located The fault point is above. Determine the wire path before, and then the fault positioning test is performed.
If an abnormal signal loss occurs when the pipeline test is terminated, it may be that some signals escape from insulation damage to the ground. When the path is determined and the general area of the fault is determined, the connection point between the pipe terminal and the ground is cut, so that the leakage current collects through the fault point. If the connection between the pipe and the ground is disconnected, the current transmitted by the transmitter will flow from the fault point, which will increase the current in the fault point, thereby facilitating fault positioning.
Connect the transmitter to the cable, the frequency is selected for low frequency, and the working mode is selected as the A-frame mode. The receiver is connected to the A frame and inserts the A frame into the soil with the appropriate forces. Note: Underground Underground Pipeline Probe Receives Operation Alarms for Error Current Test.
If the current reading is displayed during the current test, the current reading of the receiver detects the error detected. At least 5 meters before and after the cable of the depth measurement point is straight. Check if the signal in the 10 m range is relatively stable, and depth measurements on both sides of the initial depth measuring point, check whether there is adjacent interference pipe in the range of 3-4 meters near the target cable.
This is the most common cause of depth measurement errors. Signals with a strong adjacent pipeline may result in a depth measurement error of 50%. Slightly deviate from the pipeline position for several depth measurements, the minimum depth reading is the most accurate, and the position indicated here is also the most accurate.
About the use of the Underground Pipeline detector, Xiaobian will introduce you to you. If you have anything you need to understand, please continue to pay attention to Xiaobian.
