- ABSTRACT:
This study investigates the impact of economizer application on reducing energy consumption in the textile industry. It starts by analyzing the influence of traditional drying methods on both energy usage and operational costs. Next, it explains the operation of ramie machines and economizer technology. The primary focus is on the contributions of economizer application to energy efficiency. This includes highlighting the reduction in energy consumption and cost savings in operations. The study also underscores the importance of economizer application for environmental sustainability by helping to reduce greenhouse gas emissions. Furthermore, it discusses the investment cost and payback period of economizers, emphasizing how they can enhance a company's economic competitiveness. Real-world examples and success stories are provided to demonstrate the practicality of implementing economizers. In conclusion, this research underscores the significance and potential of economizer applications in improving energy economics within the textile sector. This technology not only enables energy savings but also contributes to environmental sustainability, supporting the creation of a more sustainable future in the textile industry. It also compares the energy consumption of a single-pass ramie machine with and without economizer use, assuming a 24-hour daily operation for 300 days, while thoroughly evaluating the associated advantages and disadvantages.

DESIGN AND EXPERIMENTAL ANALYSIS OF A TEST MACHINE TO DETERMINE BUCKLING IN THE RODS OF HYDRAULIC CYLINDER
- AUTHOR(S):
S. Yurekli, I. Dalmis
- ABSTRACT:
The issue of buckling is one of the subjects that should be especially emphasized in the design and dimensioning processes of engineering. In the past, this issue was not of much importance in construction and machine elements. Because the strength of the existing materials at that time was low and as a result, they were resistant to buckling due to the large cross-sectional areas of the structure and machine elements. However, in the course of time, the cross-sectional area of the building and machine elements also decreased. As a result of the reduction of the cross-sectional area, besides the advantage of getting rid of large and heavy elements, it also brought the disadvantage of buckling. In our seminar study the buckling caused by fixing the shaft at different stroke and pressure values was determined by 4 comparators and the buckling values on the shaft surface were examined.

EXPERIMENTAL STUDY OF THE GEOMETRIC CHARACTERISTICS OF WATERING ZONES FORMED BY A HANDLINE NOZZLE PROTEK-366
- AUTHOR(S):

- ABSTRACT:
The formation of the watering zone of the core of fire with a fire-extinguishing substance is primarily ensured by the design features of the handline nozzles, as well as the pressure and flow rate of the liquid. The conducted researches made it possible to reveal the dependence of the watering zone shape on the characteristics of the hydraulic system for generating fire extinguishing flows while using the typical handline nozzle Protek-366. During the exercises we studied differences in the shape of the watering zone during water supply and while using a wetting dilution of a foaming agent.

INFLUENCE OF INERTIAL FORCES ON FLOW OF ELECTRICALLY CONDUCTIVE LIQUIDS IN A TRANSVERSE MAGNETIC FIELD
- AUTHOR(S):
A. Mamedov, E. Lavrukhin, A. Murashchenko, O. Yakhno
- ABSTRACT:
In a whole range of hydromechanical equipment, there are working sections in which the flow of an electrically conductive fluid in a transverse magnetic field is realized over short sections of the channel. This kind of flow differs in a number of features from a stabilized flow. These peculiarities are due to the fact that, unlike a stabilized flow, fluid motion is implemented in the field of action of inertia forces and forces of a magnetic nature, that is, ponderomotive forces. Depending on the rheological properties of the fluid and the magnitude of this type of force, a hydrodynamic initial section is formed, which has peculiarities of the distribution of velocities, stresses and pressures. In this case, the length of this section plays an important role, since depending on it staying time of the liquid in this section can be determined, which is important in a number of technological processes associated with metallurgy, biomechanics and mechanotronic systems. In this regard, the task of forming ideas about the processes of magnetic hydrodynamics for this case is relevant. An attempt to study a similar problem in this work is devoted to the creation of both a mathematical and physical model of this flow. Based on experimental data, taking into account the rheological properties of working fluids, an attempt was made to determine the criteria characterizing this process and their influence on the hydrodynamic initial section.

- ABSTRACT:
As a natural consequence of the increase in the world population, energy needs are also increasing dramatically. At the present time natural gas and coal are generally used as energy sources. According to researchers, oil, natural gas and coal reserves will be run out in the near future. Therefore, new and renewable energy is needed to meet the energy needs for our countries. A lot of researchers have been carrying out about field of alternative energy sources. These studies generally; such as solar energy, wind energy, geothermal energy, wave energy and biomass energy. In addition to these energy conversion systems, it was also possible to mention about heat pumps with the features of low energy consumption, high coefficient of performance and environmental friendly. The presented paper is a study of general description and basic approaches on ground sources heat pumps. Ground source heat pump and history of it were explained. Some explanations were given about Ground Sources Heat Pump Systems such as Working principles, type of it, general view of advantage and disadvantage of it, hybrid type ground sources heat pump systems working principles, zero carbon footprint approach for it and also heat pump investment comparison with other systems.
