The use of underground pipeline leak detector for leak detection is an important part to ensure the normal operation of urban drainage system. This article will introduce how to use the underground pipeline leak detector leak detection work, to help the relevant staff to better complete the detection task.
I. Preparation
Before the leak detection work, the following preparations need to be made:
1. Understand the pipeline situation: Familiarize yourself with the layout, material, age and other information of the pipeline, so as to better determine the possible parts of the leakage.
2. Prepare tools: check whether the battery of the underground pipeline leak detector is sufficient, adjust the parameters of the instrument to ensure that the instrument can work normally. Meanwhile, prepare other necessary tools, such as flashlight, gloves, shoes and so on.
3. Safety measures: Before entering the underground pipeline, make sure that it is well ventilated to prevent lack of oxygen; meanwhile, wear suitable protective equipment, such as helmet and safety shoes.
Second, the operation steps
1. Turn on the instrument: Press the power switch of the underground pipeline leak detector and adjust the volume and frequency so as to hear the water flow sound better.
2. Determine the sound of water leakage: listen to the sound of water flow in different parts of the pipeline, pay attention to whether the sound of water flow is abnormal, and determine the approximate location of the leak.
3. Use a flashlight: Use a flashlight to shine along the pipe to see if there are any water stains or wet phenomena to further confirm the location of the leak.
4. Mark the location of the leak: After determining the location of the leak, use a marker to mark the pipe for subsequent repairs.
5. Record data: Record the leakage location, water leakage and other information for subsequent analysis and management.
C. Precautions
1. Keep quiet: In the process of leakage detection, keep quiet to avoid interfering with the instrument's detection of water flow sound.
2. Pay attention to safety: pay attention to safety to avoid accidents when entering underground pipelines.
3. Avoid electric shock: When using the underground pipeline leak detector, avoid contacting the power line or water source to avoid electric shock.
4. Regular maintenance: Regularly maintain the underground pipeline leak detector to ensure its normal operation; at the same time, pay attention to the maintenance of other related tools and equipment.
5. Timely reporting: After the leak detector is completed, report the leak detector result to the superior in time, so as to arrange the maintenance work in time.
In conclusion, the use of underground pipeline leak detector for leak detection requires specialized knowledge and skills. The preparation work, operation steps and precautions introduced in this paper can help the relevant staff to better complete the leak detection task. At the same time, regular maintenance and management of the underground drainage system is also an important part to ensure its normal operation.
