Introduction of hydroponic installations is a prospective direction of agriculture, while they allow to get all-the-year-round fresh vegetables, fruits and greenery, including their exotic kinds for some regions. For provision of high efficiency of this equipment (minimal expenses of energy, materials and time, maximal productivity of the plants) there is important to supply the plants with optimal quantity of nutrients (nitrogen, potassium, sulfur, calcium, magnesium, phosphorus, natrium), microelements (iron, boron, iodine, copper, zinc, cobalt, molybdenum, manganese), acids, salts. Herewith concentration of some from these additives can amount several milligrammes. So, an actual task is an accurate batching of the components of nutrients. There are several variants of an equipment for the accurate batching of liquid solutions: valves with electric control for feeding of fuel in jet engines (they have high price because of utilization of expensive materials in their construction), hydraulic engines with periodic turns of executive element for angle less than 360o (don’t provide exact regulation of turning angle) and linear electric-hydraulic engines (have other designation and design that demands of improvement). Authors propose a scheme of improved apparatus for accurate batching of the components of nutrients hydroponic installations, created at the base of the linear electric-hydraulic engine. The apparatus has a simple and reliable design and provides a possibility of high accurate batching of the components of nutrients. There are cited equations and formulas for definition of main working parameters of the apparatus, that can be used for creation of its method of design calculation.

Keywords: hydroponic installation, minimal expenses of energy, nutrients, accurate batching, linear electric-hydraulic engine.

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
