Анотація: Використання насосних агрегатів є невід’ємною складовою комунальних господарств. Вітчизняна промисловість з початку ХХ століття виробляє велику номенклатуру гідромашин усіх типів. Серед них з часом з’явився новий тип – вільновихрові насоси. У цій статті проведено порівняння насосу типу СВН з популярним насосом типу ГНОМ (грязьовий насос одноступеневий моноблоковий). Висвітлено теоретичні переваги та недоліки кожного з типів насосів на основі даних технічної документації компаній-виробників. Складено порівняльну таблицю з основними даними насосних агрегатів.

Анотація: (English) This article provides a brief overview of key fragments of an integrated technology that determine its applicability across various technical and commercial scenarios. In all cases, the focus is on a single type of device that performs dynamic mixing and simultaneous dynamic homogenization of liquid and gaseous physical media. The article explores all potential aspects of the technology and the device that implements it. Special attention is given to dynamic reagent-free homogenization as a fundamental integrative process that enhances the accuracy of non-contact monitoring of liquid conditions in pipelines. These pipelines can be monitored using aerial imaging or unmanned aerial vehicles (UAVs). For the successful commercialization of this integrated technology, it is crucial to identify all viable implementation opportunities—specifically those where the technology is clearly in demand.

Анотація: (English) When using gasoline-ethanol fuel blends, there is always a risk of phase separation into organic fractions and water (inherent in ethanol). The higher the ethanol content in the blend, the more significant the negative impact of phase separation into organic components and water. This paper proposes a device with no moving parts, installed in the fuel pipeline between the fuel pump and the high-pressure pump. The fuel pump outlet is connected to a splitting tee, which divides the fuel flow into two streams. These streams undergo turbulence-level homogenization within the device, and if water is present in the gasoline-ethanol mixture, it is dynamically emulsified during the homogenization process. The dynamic emulsion exiting the device then enters the engine’s high-pressure pump, where, under high-pressure conditions, it is further transformed into a nanoscale emulsion. Upon combustion in the cylinder’s combustion chamber, this emulsion eliminates soot formation and nitrogen oxide emissions while maintaining engine power output. These effects have been confirmed through testing conducted by ROUSH.

Анотація: (English) All specialists in the field of internal combustion engines had to deal with the key problem of these engines - low efficiency; The reasons for this phenomenon are also well known - the imperfection of the mechanism for converting reciprocating motion into rotary motion; It would seem that since the causes of power losses are in the mechanical motion conversion systems, then replacing such a mechanism with a more efficient one should resolve this technical contradiction; Over the last year alone, several thousand technical solutions have been announced in this area, but investors are in no hurry to take advantage of them; The combustion cycle of the fuel mixture in the cylinders of a modern internal combustion engine (Otto cycle) has been brought to complete perfection, its real efficiency on serial internal combustion engines has been brought to 98%, which means that during the implementation of the combustion cycle, 98% of the energy contained in the fuel is extracted; This result is achieved to a large extent due to the design of the fuel system, which has been developed to almost complete perfection, and the associated system of combustion chambers in the engine cylinders, in which combustion today occurs due to combustion at constant pressure.
