The pace of China's modern city construction is faster and faster, the scale of the city is expanding, the scale of the infrastructure is expanding, the water consumption of the city is increasing, the drainage is also increasing, and the management, maintenance, maintenance and dredging of the sewer pipeline are also increasing. Among them, the dredging of sewer is very important, which has become a work that can not be ignored by the relevant departments. Due to the problems that the residents often pour sewage and other debris in the sewer and cement mortar in the construction site, these debris are precipitated and silted. If it can not be cleaned and dredged in time, it will cause sewage overflow, pollute the environment, cause economic losses, and bring trouble to the lives of residents.
Working principle of sewer desilting equipment:
High pressure cleaning machine is a kind of cleaning equipment widely used in pipeline. It is widely used in desilting of urban sewer. Its working principle is to use the high-pressure pump to convert the mechanical energy of the power source into pressure energy. The water with high-strength pressure passes through the small hole of the high-pressure nozzle, and then converts the pressure energy into kinetic energy, so as to form a high-speed micro water jet. The powerful impact of the high-pressure water jet is used to impact the object to be cleaned, peel off and remove the dirt, so as to achieve the purpose of cleaning.
In actual work, the water is pressurized and sent to the pipeline cleaning nozzle. The pipeline cleaning nozzle and the high-pressure hose move in the opposite direction together by the reaction force generated by the high-pressure water jet. At the same time, the pipe wall is cleaned. The water from the nozzle flushes the residual sediment on the inner wall of the pipeline to the downstream inspection well, and then it is sucked away by the suction truck. When the nozzle reaches a certain distance,
This cleaning method is suitable for all kinds of sewer pipes, pure water through the purification device, can also be recycled, greatly reducing the cost of cleaning.
Features of desilting equipment for sewer pipeline:
The desilting equipment of sewer pipeline has the advantages of simple operation, high efficiency, environmental protection, no pollution, wide application range, energy saving and so on.
The cleaning length of the sewer dredging equipment can reach 150 meters, and the cleaning is cleaner through two right angle elbows
The retractor adopts hydraulic automatic retractor, which is more convenient to operate.
Low speed motor and Italian crankshaft piston pump are used to ensure the ability of long-time continuous work;
Visual pressure and regulation system, convenient application in various pressure sections, equipped with high-density water inlet filtration system;
After that, we need to remind you that we should pay attention to safety. As the sewage in the sewer pipe usually precipitates gases such as hydrogen sulfide, carbon dioxide and methane, and some production sewage also precipitates gases such as benzene and gasoline, which can form explosive gas after mixing with nitrogen in the air. The specific measures are as follows: firstly, operators must prepare labor protection equipment; secondly, they need to detect the gas in the well before going down the well; if they encounter toxic gas or lack of oxygen, they must take effective measures. In addition, when working in the well, do not light open fire or smoke. Put on the gas mask with gas belt, put on the protective belt with rope, and have other operators on the well, so as to provide necessary assistance to the underground personnel in time to avoid accidents.
