“…These destructions take place in a short period of time, about 30-40 minutes in aggressive cavitation conditions. To solve problems associated with the destruction of impellers [18,19], materials resistant to cavitation are used. Among such materials are stainless steels.…”

When considering the creation of pumps with improved anti-cavitation characteristics, the results of an in-depth analysis of the problem of pumping viscous liquids at high temperatures are presented. On the example of the technological process of evaporation of sugar syrup on a film evaporator of the latest type, the problem of the occurrence of cavitation when pumping viscous liquids at high temperatures was revealed. After analyzing the existing machines used for the specified operating conditions, critical design and operating parameters were identified that affect the appearance of cavitation. Namely, the appearance of cavitation is influenced by the reduced diameter of the impeller inlet, the diameter of the impeller inlet, the number of blades, the width of the blades and the rotor speed. To study the level of influence of these parameters, a method of physical modeling was chosen, an experimental stand was designed and manufactured. Studies have been carried out on the operation of the pump with and without a reducer. The work with a two- and three-blade inducer is analyzed, the work with an open and closed impeller, with one and two-level blade system is investigated. As a result of the analysis of experimental data, the optimal design of the hydraulic part with a three-blade reducer and a semi-open impeller with a two-level blade system was chosen. In turn, this made it possible to reduce the compression of the flow at the inlet to the impeller without loss of energy efficiency; the angles of inclination of the inducer and impeller blades were synchronized. The experience gained made it possible to design and manufacture an industrial sample of a cantilever pump with an inducer and a semi-open impeller. Thus, allowing to solve the problem of pumping thick syrup on a film evaporating unit of the Teofipol sugar plant (Khmelnytskyi region, Ukraine), with a cavitation reserve of 1.5 m.

“…Laser shock peening is an advanced peening technique, using pulsed laser energy instead of kinetic mechanical energy. It has been used in a variety of applications, including surface modification of NiTi alloy [472], of 20Cr2Mn2Mo steel alloy [473], improvement of cavitation erosion of 420 stainless steel [474], of tribocorrosion properties of AZ31B Mg alloy [475], and of tribological properties of magnesium alloy ZK60 [476]. Plasma jet [477], and ultrasonic impacting [478] were used to harden P20 mold steel and 1045 steel, respectively.…”

“…Wang et al investigated the effect of LSP on the cavitation behavior of high-strength steel. The results show that the compressive residual stress can offset part of the fatigue load, effectively inhibit the emergence of cracks, and reduce the crack expansion rate, thereby improving the cavitation resistance of the material [ 26 ]. As a result, LSP can significantly improve material properties and improve the material’s CE resistance.…”

Marine flow-passing components are susceptible to cavitation erosion (CE), and researchers have worked to find ways to reduce its effects. Laser Shock Peening (LSP), a material strengthening method, has been widely used in aerospace and other cutting-edge fields. In recent years, LSP has been used in cavitation resistance research. However, the current LSP research does not realize a comprehensive predictive assessment of the material’s CE resistance. This paper uses m stresses to develop a comprehensive set of strengthening effect prediction models from LSP to CE using finite element analysis (FEA). Results show that the LSP-1 sample (4 mm spot, 10 J energy) introduced a compressive residual stress value of 37.4 MPa, better than that of 16.6 MPa with the LSP-2 sample (6 mm spot, 10 J energy), which is generally consistent with the experimental findings; the model predicts a 16.35% improvement in the resistance of LSP-1 sample to water jet damage, which is comparable to the experimental result of 14.02%; additionally, interactions between micro-jets do not predominate the cavitation erosion process and the final CE effect of the material is mainly due to the accumulation of jet-material interaction.
