description: Theme of final qualification work: Â«Installation and commissioning of the bench for energy and cavitation tests of axial pumpsÂ».
In the framework of this work, the design of the model block was studied, in particular, the layout of the experimental bench for testing the axial pump and its 3D model. The development of the measurement scheme and the analysis of the error were also performed. The process of sealing a bench for cavitation testing is described, in particular, the technology of sealing pipe flange joints and sealing threaded joints. The analysis of modern sealing materials is carried out and the area of their application is outlined on the example of a stand. The calculation of the absolute marginal error in determining the efficiency in the development of erosion testing methods according to the data obtained as a result of the experiment. Test studies of various types of coatings are also described and, as an example, a description of two of the seventeen experiments carried out as part of the development of technology for the preparation and application of paint coatings for work on the accelerated study of cavitation erosion in hydraulic machines is given. The analysis of the results of the above experiments is carried out, on the basis of which recommendations are made on the technology of applying and preparing the final type of composite.
