“…This is explained by the fact that low-humidity feed mixtures have fairly high viscoplastic properties, which lead to a decrease in the speed in the suction line by 3...4 times. In this case, the feed mixture does not have time to fill the working chamber of the pump, and therefore the efficiency decreases and pump delivery [11][12][13][14][15][16].…”

The article presents the results of an analysis of experimental studies of a rotary lobe pump with a separator and a screw feeder. The pressure loss in the feed line, the influence of the shape of the separator and the angle between its working edges on the performance characteristics of the pump, the influence of the performance of the screw feeder on the characteristics of the pump and the influence of the rotation speed of the pump shaft on its characteristics are studied. characteristics. As a result of experimental studies, it was established that a rotary pump with a screw feeder reliably transports feed mixtures with grass paste with a moisture content of 74% or more and feed mixtures without grass with a moisture content of 68% or more at a pressure in the discharge line of 0.4 MPa. In this case, the speed of the feed mixture in the suction cavity of the pump must be at least 0.42 m/s, which is ensured by a screw feeder.

Twin wire arc spray (TWAS) is a type of thermal spray coating technology that has been extensively researched to improve the service life and overcome wear, cavitation and corrosion in pump impellers. This study aims to investigate the effect of post-heat treatment on the properties of FeCrBMnSi coatings fabricated by the Twin Wire Arc Spray (TWAS) method on 304 stainless steel substrates with varying stand-off distances. NiAl and FeCrBMnSi were employed as bond coats and top coats in this study. The substrate material was sandblasted before the coating process to achieve a surface roughness of 75-100 µm. The TAFA 9000 Electrical Wire-Arc Spraying machine's voltage (V), current (A), and compressed air pressure (Bar) were set to 28.4; 150; and 5, respectively. The coating operation was performed at 100, 200, and 300 mm stand-off distances. The specimens were then post-heated for 3 hours at 500°C and 700°C in a Thermolyne F6010 Furnace Chamber. The quality of the coating produced in this study was evaluated using thickness, hardness, wear, bond strength, micrography, and SEM (Scanning Electron Microscope) testing. According to the findings of this study, specimens with a stand-off distance of 100 mm and a post-heat treatment temperature of 700 o C produce the best coating qualities when compared to other specimens. This specimen resulted in a percentage of porosity and unmelted material, thickness, hardness, adhesive strength, and total wear rate of 7.1%, 5.53 x 10 -1 mm, 1460 HV, 24.86 MPa, and 3.8 x10 -4 mm 3 /s, respectively.

Material wear, maintenance costs, performance, efficiency, and corrosion are some of the issues that turbomachinery impellers may encounter. The optimization of impellers through additive manufacturing (AM) has been the focus of extensive research, aiming to address these challenges in turbine, pump, compressor, fan, and mixer components. This research aims to identify and analyze the main techniques currently being developed to tackle several of these issues. Evaluating the published research, the methodology highlights various AM techniques applied to impellers and related components, as well as the diverse materials used in functional system elements. The analysis revealed that the most commonly used additive manufacturing technologies for the production of turbomachinery components are FDM, with a 22% application rate, and powder bed fusion technology, accounting for 35%, utilized for high-complexity parts and even superalloys. Although more expensive, these technologies employ materials with superior resistance capabilities, surpass the limitations of conventional machining, optimize manufacturing times, and allow for the fine-tuning of multiple parameters. In terms of wear and corrosion resistance, materials such as Inconel 718 exhibited a loss of less than 0.1 mpy (mils per year) in highly corrosive environments, representing a significant improvement over traditional materials.
