Improved pump for transporting liquid feed mixtures through pipes on farms

Abstract

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.

Results of the study of rotary feed pump with separator and screw feeder

“…The experimental installation (Figure 1) consists of a rotary pump 1, a screw feeder 2, a steamer-mixer 3, a staple conveyor for feeding crushed juicy and green feed into the mixer 4, a grinder-paste preparation 5, a thermometer sensor 6, a tap for cold and hot water 7, 8, level gauge 9, pressure gauges 10, feed pipe 11, valve for adjusting the flow and pressure of the pump 12, measuring tank for determining the flow of the pump 13, fecal-mud pump FGS-50/12.5, hopper for receiving combiforms 15, screw conveyor 16, safety valve 17 and other measuring instruments [2]. The installation works as follows.…”

“…However, the insufficient quantity of these feeds and their high cost hinder the increase in pig production. The introduction of succulent or green feed into feed mixtures makes it possible to save concentrated feed and at the same time increases the biological value of diets [1][2]. However, the introduction of succulent or green feed into feed mixtures changes the physical and mechanical properties of feed mixtures, i.e.…”

The dependence of the amount of energy obtained by solar cells on the temperature of the environment

“…This energy is several thousand times more than the current energy needs of our planet. For these reasons, nowadays, solar batteries are widely used in organizations, enterprises and households in order to meet the demand for electricity [3].…”

Development of a simulation model for assessing the technical condition of oil power transformers by measuring vibroacoustic parameters

“…Extending the life of these devices is a priority to ensure reliable and stable power supplies [18][19][20][21][22][23][24]. In this context, diagnostics of oil-based power transformers plays an important role [8,22,[25][26][27]. Oil power transformers are technically complex devices designed to change the voltage of electrical energy in order to transfer or distribute electrical energy over networks [9,14].…”
