  • Development of a cooling system for the vacuum chamber of a multicomponent nanocomposite coating facility

    The global economy growth and active industrial development are limited, among other things, by the capabilities of existing technology. The potential for improving the functional characteristics of classical materials is practically exhausted, and the widespread use of new composite materials and high-enthalpy alloys is limited by the high cost and complexity of the technological process of their manufacture and processing. Knowledge of the materials physical-mechanical, thermophysical and chemical characteristics proves that the surface structural-phase state in many cases is crucial in the processes of wear, fracture, chemical and thermal destruction. Thus, the issue of developing technologies and equipment for modifying the surface layer and creating multicomponent coatings, including nanocomposite ones, is urgent. Current article presents the results of a study devoted to the creation of a facility for such coatings deposition by plasma spraying. One of the key elements of technological equipment for this method is a vacuum chamber, which is exposed to intense thermal stress during operation. Thus, the issue of designing a cooling system is relevant. To reduce the material and time resources at the design and experimental development, the temperature state of the chamber was simulated. It is shown that to ensure safe operation, it is advisable to use water cooling. The simulation results confirm the operability of the vacuum chamber cooling system under operating conditions. The following operating parameters were determined: the inlet pressure is 0.6 MPa, the water flow rate is 2 l/s, and the mass average temperature of the outlet water is about 40°C.

  • Detection of a violation of electricity metering of the consumer

    The method is considered for seaching a single-phase or three-phase electricity meter with the radio control module installed in it. With the help of this module, the consumer of electric energy has the opportunity to disconnect the pecking motor of the electric meter. These actions are allow you not take into consideration actually consumed elecrtrical energy. This module is installed by the consumer illegally and when a network organization detects this , they make an act about unaccounted electric power consumption. The method is based on the measurement of the intaking power of the volt circuit by the maser gage CE601 of the analyzing counter of electrical power CE 101, with the mechanical counting mechanism. Herewith, the consumer's loading is switched off by supply feeders. This method is allow to draw the conclusions about the presence of embedded non-factory devices without disconnecting of the electricity meter from the network ( time saving ).
