Background
Since the birth, the impeller is a very important mechanical part for conveying gas, liquid and particles of human beings, and setting up the labor of sweatband for ship, aerospace propulsion and the like. Impellers are generally classified into three categories: the open type impeller, the semi-closed type impeller and the closed type impeller are important essential elements which are selected to be applied in different working environments according to different requirements. But there are also some unsatisfactory places, such as: the impeller is always in a rough universal pushing state due to the limitation of a water pressure environment and an air pressure environment when sailing on a ship and the blades of an airplane are in flight, and if the thrust is improved as much as possible, the thrust can be improved only by increasing the form of the impeller and the form of power at the same time. The cost-effectiveness ratio can not always have a great breakthrough. The disadvantages are as follows:
1. the open impeller (blade) has the phenomenon of extensive thrust in operation, and the occurrence of the phenomenon can cause the thrust of the blade to be weak and not reach the expected thrust speed and efficiency. Such as: naval and aircraft blades, which are essentially impossible to achieve high speeds.
2. During the operation of the open impeller (blade), the generated thrust is always in a scattering surface state, and the scattering surface just disperses and weakens the reverse thrust generated by the blade. Therefore, the frontal thrust of the blade is greatly reduced, the acceleration of the blade cannot be improved, and the thrust is not strong.
3. The open impeller (paddle) is in an external air pressure and water pressure environment with too large flexibility, so that the thrust of the paddle cannot be kept in a stable high-pressure state, and if the rotating speed of the paddle is increased twice, the thrust is increased exactly in a reverse way, so that the paddle is stalled or slipped, and the thrust is weakened or disabled.
4. In the application of the open type blades (impellers), single blades (impellers) are adopted, and one blade (impeller) is difficult to generate acceleration thrust and needs to be changed.
One specific reason is the rough flooding limit that all of these impellers cannot evade. To change the situation, a new high-efficiency structural form of the impeller must be obtained, an environment that the impeller exerts high energy is created locally, the situation of extensive pushing can be avoided, and the efficiency of efficient pushing of the impeller can be improved only by effectively solving the problem of extensive pushing of the impeller.
