“…The resulting point 2 will be connected to the point of the trailer O, and in the power polygon we will draw a line parallel to the direction 2-0, intersection with the direction of force N. The intersection point determines the values of N and the traction force Rzx, at which the system will be in equilibrium. Expanding the force Rzx in the direction of the links, we find the magnitude of the efforts РB and PH acting in these links [14].…”

Rational use of water resources, improvement and development of new technology and technical means for its implementation, ensuring the economy of irrigation water is one of the most important issues of today. This article is devoted to the issues of technology for improving the method of irrigation along furrows and creating a technical means, running in and testing directly on experimental fields, selected in each region of the proposed technology and the created technical means, technical requirements for a machine for cutting furrows with a given slope and profile, as well as analysis the results obtained. A database has been created for the mechanization of existing technologies and technical means of cutting furrows along a given slope and compaction of soil in their beds with the formation of a design section and a longitudinal profile of a furrow on the lands of farms in arid zones. A project of technological maps for the production of cutting grooves with a given slope and with a variable density of their bed, taking into account the granulometric and volumetric composition of the lumps, has been drawn up.

“…Fish and poultry feed should be crushed. Taking into account the above, the analysis of today's available devices [7,8,9,10,11,12,13,14,15,16] was carried out to create a small and compact blue stem feed grinder. According to the research results, a feed grinding device for fisheries and poultry was developed.…”

Uzbekistan pays a lot of attention to fisheries, poultry and animal husbandry. In fish farming, poultry and livestock rearing, it has been recommended to give green feed as a supplementary feed, which reduces the accumulation of excess fat in fish. In this regard, a grinder was produced for cutting plants with blue content. The number of rotations of the feeders was studied theoretically and experimentally in order to meet the demand of the prepared feeds. According to the theoretical research, the cutting length of blue stalk feed is achieved by changing the number of revolutions of the shredder drum depending on the feed speed Vuz and the number of blades in the drum N p , and the number of revolutions of the feeder blades when the feed is transferred at an angle of 27O is 101-207 r/ in the range of min, when the number of blades is in the range of 4-6 pieces, it is recommended that the number of rotations of the shredder drum be greater than 1358 r/min and 1478 r/min to ensure a cutting length of up to 10 mm.

“…Currently, in the vast majority of cases, condition monitoring is carried out without taking into account the possible non-stationary nature of the development of faults, which creates the problem of ensuring control of the state of a centrifugal pump unit during operation to prevent sudden failures of the units. Therefore, an urgent task is to develop new and develop existing methods for monitoring the condition, diagnosing and monitoring a centrifugal pump unit, taking into account the identification, control, and prediction of damage accumulation processes in parts and multi-stage failure of rolling bearings [1].…”

Reliable operation of a centrifugal pump unit, as an electric motor, which is a reliable link in the composition of a centrifugal pump unit, depends on many factors, as well as an important factor in the trouble-free operation of a centrifugal pump unit is the reliability of rolling bearings. The presented work is devoted to the study of the processes of multi-stage failure of the parts of the rolling bearing of a centrifugal pump unit, i.e., repeatedly occurring self-eliminating failures of the same nature - intermittent failures, establishing the dependences of vibration changes in the degradation process, developing control methods and developing methods for identifying and predicting staged failure processes.
