1. "Determination rotor turbine's centrations on the change of spatial position of supports"

authors: Probachay Alexey

          Operational changes of centerings of a turbine unit specify in unequivocal necessity of the control of entered amendments at car assemblage in a cold condition.

          Use of preliminary factory factors of change of rotors in a cold condition does not give optimum values of reactions on support of bearings in a heated-up condition and carrying out of additional works under indemnification of the caused changes by carrying out of balancing works is required.

        Spend of the time for starting-up and adjustment operations, including centering and vibration level, is offered to lower expenses by reception of new values of parametres of centering on the received values of change of position of support of the turbine...

2. «providing of low vibroactivity on the example of turboblower, consisting of turbine of OR-12PV, reducing gear of B-10 and ventilator of VDN-36X2»

authors: Probahay Yurii, Probachay Alexey

          Change of excentricity, and equal and disbalance on the rotors of VDN related to the phenomena fixing and liberations of the resilient bending  at the change of temperature and increase  of deformation of wheel  from stretchings  centrifugal forces. The large overfalls of temperatures between a wheel and billow cause the phenomena fixing and liberation of the resilient bending, that possibly at the sharp increase of coefficient of heat emission from smoke gases to the rotor of vozdukhoduvki from condensation of moisture on a wheel, if TVD off., and also  at subsequent his snap-chilling after including…

          The article consists of problem description, measures of fight and optimization of works for the increases of oscillation reliability, related to the temperature bending of billow TVD...

3. МПК8 F16 F 3/02. "Vibroinsulator of foundation"

authors: Ilushenko V., Ilushenko I., Probachay A.

          Device is characterised by the simplified design as does not require use exclusive or difficult in manufacturing of structural units, and has only two fixing knots. Thus, use offered виброизолятора the base under the equipment of the simplified design provides increase of its reliability and decrease in dynamic loadings...

4. «The application of the heat pumps for heat recovering and in heating systems»

authors: Probachay Alexey, Saf'yants Artem

          The goal of this research is the analysis of separated block of flats' heating system based on heat pumps and is this system's optimization considering a number of parameters, including cooperation with existing central heating system.

          Conclusions , got in-process:.

1. Applying heat pump coupled with additional peak heat source leads to 50% energy saving due to properties of the heat pump and recovering heat of ventilated air.
2. Using heat pumps separately or coupled with another heating source improves heating system reliability and safety.
3. The best circuitry is the one, which includes reconstructing of the existing heating system and using it coupled with the heat pump.

5. "Estimation of the state of mechanical equipment on the losses of power on a vibration"

authors:Sidorov V., Sidorov A., Serebrov L.

          The method of estimation of the technical state of mechanical equipment on the general level of vibration is standardized, simple, has a row of programmatic decisions, that provided his wide distribution. But it should be noted and row of assumptions which allow to contest the got results, the method of estimation of the technical state of mechanical equipment is therefore resulted on the losses of power on a vibration, which allows to give up procedure of determination of class of machine and produce the single system of scopes of areas of the technical states.
