CCTV detection (central control industrial pipeline endoscopic camera) technology, in some developed countries and regions in the world, has been applied to the system inspection of drainage pipelines, prevention of pollution caused by leakage, and monitoring and prevention of geological disasters (such as landslides). .
CCTV detection is a new type of application engineering technology. It uses the industrial pipeline endoscopic camera system to continuously and real-time record the actual situation inside the pipeline. The technicians perform the on-site location of the problems existing inside the pipeline according to the video data captured by the camera system. The determination and the nature of the defect are real-time, intuitive, accurate and certain forward-looking. In the active prevention of environmental protection and the adoption of targeted technical measures, the maintenance of drainage pipes, the elimination of rain, the stagnation of sewage and the prevention and control Pipeline leakage pollution provides a reliable technical basis.
CCTV testing is mainly used in:
Environmentally friendly sewage leak detection
Completion acceptance of new drainage system
Completion acceptance of drainage system renovation or dredging
Sewage treatment plant receives excessive unexplained infiltration or insufficient water supply through the drainage system
Investigation of causes such as pipeline siltation and poor drainage
Detection of the combined flow of directly discharged sewage and treated sewage
Detection of corrosion, damage, interface misalignment, siltation, scaling, etc. of pipelines
Find repair wells or unidentified pipe segments that cannot be found due to drainage systems or infrastructure construction
The sonar detection system is suitable for the detection of siltation, scaling and leakage failure of sewage pipelines with high fullness of sewage, large flow, and unable to stop water due to production discharge, etc., and is not suitable for CCTV detection. ) Pipes of various materials ranging from 125mm to 3000mm, the test results are processed by professional software, and the results have an intuitive effect.
The application of sonar detection provides a scientific basis for targeted pipeline maintenance and ensuring the normal operation of the pipeline; it can be used to carry out the drainage pipeline with large discharge, short discharge interval or continuous discharge under the condition of ensuring complete normal discharge. Detection; is the most advanced and effective method for the detection of drainage systems in the world.
High-pressure cleaning uses the high-pressure water flow generated by the pipeline high-pressure cleaner to flush the inner wall of the pipeline. The water piston formed in the pipeline centered on the spray head is pulverized and dragged out by the forward movement of the high-pressure hose and the repeated movement of the backward traction to achieve the purpose of cleaning and unblocking the inside of the pipeline. High-pressure cleaning is the most effective way to clear the pipeline when it is silted and blocked.

Important Caution:
1． Before use the glue gun, check if the plug cord into electrical outlet properly;
2． When glue gun in first use, the heating element will have small smoke, it is normal situation, but the smoke will disappeared after 10 minutes;
3． After power, not for a long time in standby mode(not longer for 20 minutes), when the suspension of use, unplug first.
4． Avoid to use the glue gun under very hot or very cold environments.
5． Better not work under direct cold wind blowing, it will reduce efficiency and loss power
6． When in continuous using, do not press the trigger with great pressure, and try to squeeze out the un-melted glue, it would damage the glue gun
7． Not applicable for bonding heavy objects or objects needed strong adhesive
8． The quality of glue stick will directly influence the glue gun function and sticking objects quality;
9． If the power cord is damaged, do not replace it by yourself, must ask for professionals to replace it.
10． This tools must b e placed in its position when not in use. And storage before the tools complete cooled.
11． Be careful when using any other electrical appliance with flammable material.
12． Not applicable for a long time in the same place.
13． Do not use an explosive gas atmospheres.
14． Note that heat may be the line of sigh, combustible materials.
15． Do not leave equipment unattended when switched on.
16． This appliance is not intended for use by persons(including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
17. Children should be supervised to ensure that they do not play with the appliance.
Using methods
1. Glue gun using voltage is 110-220V AC,50/60Hz;
2. Tip gun forward on stand and place a piece of cardboard under the nozzle
3. Use 7-8mm (mini trigger glue gun), 11-12(big trigger glue gun), insert glue sticks through
tunnel at back of gun
4. After power, wait for 5-10 minutes to allow glue to soften
After glue softens, squeeze trigger to feed glue through glue barrel. Excessive force will damage glue gun. Put down nozzle after work, disconnect the power plug20W Glue Guns, 20W Mini Glue Gun, Regular Glue Gun
