When using underground water detection, the following points need to be noted:
1. Inspection and Preparation: Before starting the detection, the pipe joints should be inspected to ensure that all joints are properly tightened to avoid misdetection. At the same time, the pipeline should be pressurized to check whether the system is properly sealed.
2. Environmental factors: Pay attention to the weather conditions, avoid testing in rainy days or high humidity environment, so as not to interfere with the test results due to environmental factors. In addition, the greater the temperature difference between the pipe temperature and the ground temperature, the clearer the pipe direction presented by the pipe locator, which helps to locate the leakage point more accurately.
3. Operation specification: follow the instruction manual to operate the underground water detection, and use the necessary personal protective equipment. For high sensitivity detection, it is necessary to deal with the surrounding noise interference to ensure the accuracy of detection.
4. Precise positioning: In the relatively quiet conditions of the indoor environment, pressurized using underground water detection along the marked pipeline location for one by one inspection. When you hear a sound similar to the sound produced by gas splashing or water flow, and the size of the sound is significantly higher than other areas, while observing the underground water detection screen, the spectrum signal is significantly higher than other places, may have been localized to the suspected leakage point. After the need to retest to verify the leak again, when the signal value of the highest point and the location of the suspected leakage point coincides with the water leakage point has been locked.
5. Follow-up: After the repair is completed, the water pipe leakage detection needs to be carried out again to ensure the quality and effectiveness of the repair. At the same time, it is also very important to choose the right pipe material, check the pipes regularly and carry out the necessary maintenance.
In conclusion, when using underground water detection, you should strictly follow the operating procedures, pay attention to the environmental factors to ensure the accuracy of the detection results, and do a good job of quality checking and pipeline maintenance in the follow-up treatment.
