“…At the same time, of course, it is important to address the audience with problematic questions during the lesson, to direct them to creative and scientific thinking by creating problematic situations in the lecture. In addition, the creation of online training courses, including the use of technologies such as project style [25], scientific and creative thinking, enriching the online course module platform with electronic resources [26], including video and audio lectures, gives great results. In short, there is a need to pay more attention to education in the use of improved pumps on farms.…”

Improved pump for transporting liquid feed mixtures through pipes on farms

et al. 2021

The article substantiates the effectiveness of the use of liquid feed when feeding pigs, shows the advantages of feeding with liquid feed rather than dry feed. It is stated that, when feeding with liquid feed, pigs of some production groups reduce the need for drinking water, while the energy consumption for surviving feed and saliva secretion is reduced to a minimum. The transition to liquid feed mixtures of low moisture content, which include juicy feed or green pastes, is considered rational, but the equipment used for transporting and distributing such feed mixtures requires the improvement of working organs. However, the use of pipeline transport for transporting and distributing feed mixtures on farms and small family farms requires the use of special feed-transporting pumps with high reliability. But, the industry does not produce special pumps for feeding feed mixtures of high concentration with a moisture content of 68…. 75%, and the use of pumps from other industries does not give effective results. Therefore, the development of a pump used for feeding feed mixtures with low moisture content is very urgent. To solve this problem, the authors have proposed a new energy-saving pump design used for feeding liquid feed mixtures through pipes on farms and small farms. Devices and the principle of operation of the improved pump are given. The novelty of the design is confirmed by the patent of the Republic of Uzbekistan UZ 5149B.

“…The B/H value was 26-63 in the area above the water intakes and 63-77 in the area below the water intake. The value of the surface water flow velocity in the area above the water intake changed from 0.78 to 1.08 m/s, below the water intake -from 0.5 to 0.75 m/s [17][18][19][20][21][22][23][24][25][26]. The optimal route and boundaries of the location of the pioneer ditch are assigned depending on the location of the main stream of the river relative to the point of the damless water intake.…”

The adjustment work canal on the Amudarya in the areas of the damless water intake

et al. 2021

View full text Add to dashboard Cite

The paper presents the results of field research in the area of the damless water intake of the KMC on the Amudarya River. The article developed the optimal route and boundaries of the pioneer digging location, depending on the area of the main stream of the river relative to the point of the damless intake. It also provides hydraulic calculations for improving the condition of a damless water intake and recommendations for the rational use and placement of a dredgers fleet when laying a route of a ditch and cleaning it.

“…Depending on the transporting capacity of the water supply facilities, the water velocity may decrease to a value less than the non-lagging value (this is mainly in the front chamber and water intake chambers), as a result of which suspended particles are deposited at the bottom of the structures. This leads to a change in the design dimensions of the forechamber, clogging of the water intake chambers, which negatively affects the operational parameters of the pumping units [5,[21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

A device for reducing the siltation of the front chamber of the pumping station in irrigation systems

et al. 2021

View full text Add to dashboard Cite

It has been determined that the reduction of siltation of the front chamber is necessary because the deposited sediments seriously violate the planned hydraulic structure of the flow when water is sucked up by pumps, as a result of which their efficiency decreases. The method of calculating the pipeline system of a new device designed to significantly reduce the siltation of the front chamber of irrigation pumping stations by artificially creating turbulence in the water flow in the bottom layer of the structure is presented. This calculation methodology is based on the use of the theory of flooded water jets, which makes it possible to determine the main characteristics of the jet. The latter allows calculating the design parameters of the pipeline system. The results of experimental studies are presented to compare the calculated data with the results of experiments, as well as to determine the effectiveness of the proposed device for a significant reduction in siltation of the front chamber of irrigation pumping stations.
