Abstract

We consider the manure removal system, which is used in most pig farms being built and reconstructed at present in Ukraine, and it has been discovered that there are major mistakes during the baths construction in the correct geometry and depth, and therefore discusses their rules of operation. If the baths geometry is wrongly executed, for instance, if the slope is made to slant toward the bottom of the tub filler drain pipe, which in itself is unacceptable, or not properly executed in the form of a special pit steps towards the neck drain, and etc., then a number of problems is inherent of its exploitation. The basic requirements for laying fused-pipe is compliance with its slope. The considered equipment must be equipped with pumping stations to pump manure. The pumps for pumping manure: submersible sewage pumps and dry-installed in the mine and long sewage pumps with electric or PTO shaft of a tractor were analyzed. Attention was paid to the designing of modern equipment for the distribution of manure waste into fractions. The classification of manure storage and the basic requirements for their placement and arrangement was carried out, and recommendations are made for the designing of pumping stations, to select pumps for the pumping stations and the design during the modern construction and reconstruction of old pig farms.

Abstract

The article considers issues of ensuring sustainable agricultural production by increasing reliability of an irrigation sys-tem and water security. The article describes results of hydraulic tests performed at the water outlet with a vertical move-ment valve member. Resistance coefficients and hydrodynamic effects at the water outlet were determined experimentally. The study devel-oped a method for calculating hydromechanical transient processes in the water outlet at the stop and start of the pump. The paper substantiates the new construction of a water outlet facility with a vertical displacement of the breakdown valve. Such a design better corresponds to peculiarities of the operation of pumping stations and, if there are water pipes of considerable diameter, it has a positive effect on transition hydrodynamic processes by reducing the number of failures and downtime by up to 10%.
