The paper study of the vibrating bucket of the manipulator as an excavator or tunnelling shield, with energy-saving adaptation to the aspects of the working environment for use in the construction and mining industry. The use of buckets and vibro-impact devices with automated operation allows a reduction of energy consumption for the destruction of rocks and hard soils with adaptation to their properties. The article proposes an algorithm for optimal control of the vibro-impact bucket element - a vibro-impact device using restrictions on the cutting resistance force and impact energy. The range of functioning of the vibro-impact device is determined. The optimal area of switching on the device is established, depending on the variable aspects of the working environment. The integral characteristic, such as the cutting resistance force of the soil, were used. It finds that this characteristic depends on the angle of rotation of the manipulator's bucket and the soil density's attribute by the number of impacts of the DorNDI impactor. The influence of thermodynamic parameters on the impact energy during the functioning of the vibration impact device in a real environment is observed by considering the polytope index of the gas compression process in the pneumatic accumulator. The work establishes the critical level of the force of static cutting of soils by an excavator of the IV size group for Ukrainian production and the criterion for the transition of the cutting process from static to dynamic mode depending on the variable characteristics of the working environment. The energy characteristics of the adaptive vibration-impact bucket of the manipulator are given. Introducing the vibro-impact bucket into the industrial production of Ukraine is recommended.

The expediency of conducting research in the direction of improving the energy efficiency of submersible induction motors due to the introduction of a set of tools for the design synthesis of their innovative designs was reasoned. Means of design synthesis of submersible induction motors of innovative designs are considered. The combination of which in the implementation of the design will allow to increase the level of improvement of submersible induction motors in accordance with the requirements for modern equipment, such as: reliability, energy efficiency, economy. The results of realization of the induction motor optimal design synthesis of the submersible pump of an innovative design on the basis of the ПЭДВ 2.8-140 motor by criterion of a maximum efficiency are resulted.

Developed a complex mathematical model of the electromechanical system of oil production by means of the submerged centrifugal pump. Received an expression of the complex criterion of efficiency of system taking into account stages of extraction and repair of a well, as a ratio of volume of extracted oil to the consumed energy during a cycle of the analysis of processes. Mathematical model of the system: asynchronous motor - pump - hydraulic network is implemented in the simulation system and provides a study of the relationship between the amount of energy consumed and the efficiency of the system - the volume of oil produced. The developed complex mathematical model provides optimization researches taking into account nonlinear properties of components of system, their mutual influence. The initial information in determining the design parameters of the model components is the power of the induction motor of the pump, the geodetic height of the oil, the maximum efficiency of the pump, as well as for the point of maximum power of the pump operating range: engine load, hydraulic efficiency of the well and pipeline. The pressure characteristic of the pump is approximated at points of limits of the working range. Approximation of the pressure characteristic and efficiency of the pump is carried out taking into account changes of sizes of giving and speed of rotation. According to the simulation results, recommendations for improving energy efficiency using means of minimizing hydraulic losses in the process of well repair: optimization studies of the dependence of the change in the value of the energy efficiency coefficient as a function of production period while varying the duration of the repair period. For the example studied, increasing the repair time by 2.5 times reduces the overall energy efficiency of oil production by 20%. Also, energy efficiency decreases by 5% by reducing the extraction period from the optimal by 35% and by increasing by 65%.
