    Front-end plows are promising and carry out smooth plowing. A significant disadvantage of the front plow is that the housings do not completely rotate the layers within their own furrow and have a large traction resistance since they work in conditions of blocked cutting. The study aims to substantiate the technology of turnover of a polygonal formation in conditions of non-blocked cutting. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. The parameters of the polygonal formation formed by the angle beam and the body of the plow have been studied. Analytical dependences for determining the coordinate of the center of gravity of the formation and the displacement of its center of gravity along the ordinate axis are obtained. It was found that the displacement of the center of gravity of the formation along the ordinate with a formation width of 45-52.5 cm and a gripping width of the angle of 4-10 cm is 4-10 cm

    Plow for processing row spacing of gardens

    Full text link
    Existing plows do not provide high-quality tillage between rows of orchards and vineyards. The purpose of the study is to develop and justify the parameters of the plow for cultivating the soil between rows of gardens to tractors of class 0.9 kN. A design scheme of a single-body plow for smooth, rowless plowing of garden aisles has been developed. The proposed plow consists of a movable and fixed frame, a disc knife, a screw body with a hostage. The research uses the laws of agricultural mechanics, mathematical statistics, and methods of strain measurement. The technology of cultivating the soil between rows of gardens with a single-body plow for smooth plowing is justified. To implement the proposed technology, the position of the plow body changes relative to the tractor during operation. It is established that when equipping a plow with a movable and fixed frame and performing a body width of 45-52. 5 cm, the required plowing quality is achieved with the lowest energy consumption

    Scientific bases of control of vibration of hydrodynamic origin in centrifugal pumps

    Full text link
    The reliability and efficiency of pumps, like any machines and mechanisms, is determined by a number of factors, including their operating conditions and the ability to adapt to changing operating conditions. This article is devoted to the development of scientific foundations for controlling vibration of hydrodynamic origin in centrifugal pumps. The failure of a centrifugal pump due to fatigue failure of a rolling bearing does not occur suddenly and not instantly. First, some signs of the approach of this process appear, the nature of the vibroactivity of the aggregate changes. Against the background of a stable vibration level, some vibration outliers appear. The study of the sequence and intensity of these emissions is important information not only about the approach of the moment of destruction of the rolling bearing parts, but also about the operating time that the operating personnel still have to take measures to eliminate an emergency and complete catastrophic destruction
