Use large propellers for replacement
With the development of science and technology, nowadays the level of machinery and equipment is constantly improving and innovating. The improvement and innovation of machinery and equipment have improved the efficiency of production and processing. Large-scale propellers are mostly inconvenient to install and use. Most of them belong to an integrated structure. When damaged, they need to be replaced as a whole. The replacement cost is high. At the same time, the integrated structure is bulky and inconvenient to install. The shape of the spiral blade is relatively simple and cannot meet the needs of the market. Therefore, to solve the above problems, it is necessary to improve on the basis of the original equipment to meet the needs of the market. When using the large propeller, the mounting sleeve 1 is installed on the drive shaft through the fixing card 2, and then the mounting base 3 is fixed on the mounting sleeve 1 by the first pressing bolt 11, and then the pressing card 4 is passed through the second tightening bolt. The pressure bolt 12 is installed on the outside of the mounting seat 3, and then the anticorrosive sealing plate 8 is embedded inside the foundation 5 to avoid the problem of corrosion of large spiral blades after long-term use, and then the installation blade 7 is embedded in the base propeller 5. On the outside, the mounting blades 7 of different dimensions can be installed according to different devices, so that the device has a wider application range.
