05.20.00 Processes and machines of agroengineering systems
DescriptionWe have made calculations using the values of dung delivered after the analysis of laboratory research of the soil and irrigation water delivered with organic fertilizers. Based on the data on values of hydraulic resistance coefficients of mixer elements, mixing chamber and diffuser, we found diameters of pressure pipelines, reduced head of NGPR mixer, velocity of flow discharge from mixing nozzles and the mixing chamber. According to the design data of the pump head values, those of the mixer head, the head on inlet into the mixer and head in a reservoir of constant pressure a possibility was received to specify values of factors under studies on location of irrigation system and to test the design data with the help of the experimental value received. A low head system with hydraulic and geometric parameters of mixing is recommended for small farms

CALCULATION OF THE UNSTEADY WATER LINE IN THE KRASNODAR SUBURBAN CHANNEL FOR WATER MEASUREMENT
DescriptionLow level of water accounting and poor control in water distribution in the irrigation system are the main negative factors of industrial influence on irrigated natural complexes. Complex ecosystem way to control water resources involves qualitative improvement and optimization of all parts and elements of irrigation system, from the headwater pool, main channels to local water distribution channels. In this regard, when engineering, constructing, using some new and reconstructed old irrigated systems, the most important problems are the optimization of water use from natural water resources, development and use of highly efficient water-saving and energy-saving technologies of water distribution and water use in the irrigation system. The problem of economical and efficient consumption of water resources on the studied water complex cannot be solved successfully without any related consideration of water accounting and water consumption questions based on system principles. System principles are supposed to collect, analyze and use the information, with the help of complex technical means, which are used for water measurement in conditions of water charges, and for the purpose to control the technological processes of water supply and water drainage, when the needs of water users are satisfied and the environment get less damage. In the work, we study the mathematical calculation of the unsteady water line in the Krasnodar suburban channel for water measurement. The imitated research of hydraulic processes were carried out on the mathematical model of water measurement, based on the characteristic methods, with the use of analytical solution of ordinary differential equations of the initial characteristics. The use of the considered method of water measurement in irrigation channels with the use of analytical solution of ordinary differential equations of initial characteristics will allow to optimize the processes of water measurement and to minimize idle and non-technological discharges of water from the system

Description
The calculation of pumping equipment and piping network parameters is presented. The method of cutting impeller pump diameter for optimal performance of pump unit with piping system on efficiency value is shown. The case of operating the distribution network and pumping station with three pump units D1250-25 is considered. Procedure of construction of loss-of-head curves in pipes, determination of the actual operating parameters of a single pump unit, selection of pump impeller diameter for essentials is indicated. Four points for graphing such curves are presented. According to the first point the whole network is divided into sections with suction, pressure main pipelines and pipelines with changing water flow compared with the previous ones. The second point involves definition of the electrical resistivity of each site. The resistance of network analyzer is determined in the third point, the loss-of -head of the whole network is determined in the fourth point. The article presents the scheme of pumping station with three pump units connected in parallel and a distribution network (Figure1), loss-of-head curves in pipes regardless the number of working pumps (Figure 2), the order of constructing three loss-of-head curves with operating one, two and three pumps with normal and cut pump impeller diameter (Figure 3 ), the order of determination of the actual parameters of pump work characteristics according to combined characteristics of normal and cut pump impeller diameter ( Figure 4) In conclusion, it is stated that the question of proper definition of actual parameters of pumps and the support of these parameters in optimal mode remains open due to the lack of proper methods of constructing loss-of-head curves pipeline. Every similar calculation is preliminary and should be carried out in field conditions

ESTIMATION AND SELECTION OF THE MOST OPTIMAL VARIANT DRAINING PONDS
DescriptionThis article gives estimation of drying (liquidation) ponds with subsequent selection of the most optimal variant. For example, ponds № 1, 2 have the calculations for the four drainage options: bottom outlet, using a mobile diesel pumping stations, through the siphon outlet, as well as the combined option of draining (via a bottom outlet and mobile pumping stations). The results of the calculation for each of the cases were examined; the article summarizes the estimated parameters, which allow to visualize and choose the most optimal variant of drying, depending on the time of evacuation

Description
The article presents the design study for construction of a drainage system on the territory of gardening association «Zarya» in the region of Gukovo in Krasnosulinsky district of Rostov region. Construction of a drainage system is a prerequisite for reducing the groundwater level caused by the infiltration of the drainage complex mine called Burgustinskaya. The results of the calculations determined the value of the total infiltration groundwater feeding; inflow rate to each of the 6 drains per unit length, water flow ability of a horizontal pipe drainage, as well as a diameter of drainage pipes
