Submerged sewage pump is widely used in municipal engineering, factories, trade, hospitals, hotels, residential areas and other sewage discharge because of its simple installation, small footprint, convenient maintenance, no noise and other advantages. At present, submersible sewage pumps in China are mainly produced and manufactured by domestic manufacturers, and the products of a few departments are imported from abroad. The market prospect is very broad. However, because the reliability of the submersible sewage pump needs to be strengthened, improving the technical content of its products is the main direction for the company's future development. In view of the submersible pump's existing problems, some domestic manufacturers have put their energies on the development of the pump protection system: automatic alarm or blockage of the power supply when the pump operation is abnormal. Although this method can have a certain effect, and this protection is also necessary, but this is not the fundamental method to solve the problem, we must focus on improving the function of the pump, the fundamental solution to the problem.
In addition, the development of the product fully takes into account environmental issues, so that the research and development of products are more energy-efficient and environmentally friendly.
To sum up, the problem to be solved in the future of submersible sewage pump is to improve the reliability of use, to adapt to a variety of work environments, optimize its structural design, and further improve the performance of submersible sewage pumps.

Inclined Construction Elevator
The main steel structure of the construction hoist has been optimized design, which not only considers the mechanical properties of the steel structure, but also meets the functions of using, manufacturing, transportation and installation.
The main body of the cage is welded with high-quality channel steel (material: Q355B or Q235B) and square tubes, the structure is reasonable and appearance is beautiful; the bottom and top of the cage are made of non-slip patterned steel plates, and the top of the cage is equipped with railings; The semi-inlaid electric control cabinet structure and the standardized cable protection groove effectively improve the using space and electricity safety of the cage.
The standard section is welded by φ76×4.5 high-quality round tube (material: Q355B), angle steel, etc. through multiple sets of special robot welding process equipment, with a special rack for transmission on the side; The high precision of multi-process and tooling ensures the high interchangeability of the standard section, and the size deviation of each part is far better than the national standard requirements, which directly improves the smoothness of the equipment operation; After welding, the standard section undergoes an overall shot blasting treatment and a special painting process to eliminate structural welding stress, improve the wear resistance of the material surface, and paint the inner wall of the steel pipe to enhance its own protection ability and increase the service life.
The attachment device is mainly connected by a front connecting rod, an adjustable middle connecting rod, an adjustable long connecting rod and other components through fasteners and bolts; the horizontal and height directions have a large adjustment range and flexibility.
The fence is mainly composed of angle steel and woven mesh, etc., with neat and beautiful structure.
