EVALUATION OF OPERATIONAL RELIABILITY AND EFFICIENCY OF PRIMARY DESIGNS OF PULSE SUPERCHARGERS USING HYDRAULIC SHOCK ENERGY

Objectives. The transition to pulse circulation of the working medium in effective systems of heat and water supply result in a need to improve the technology used to organise pulse coolant circulation, as well as to develop fundamentally new technical solutions for pulse superchargers that use the energy of local hydraulic shocks. The aim of the present study was to evaluate the known designs of pulse superchargers of water-lifting devices in terms of operational reliability and efficiency in hydraulic heat and water supply systems.

Methods. The design features of pulse superchargers using hydraulic shock energy are analytically generalised. Methods for analysing the reliability, efficiency and conditions for selecting the pulse superchargers used in water supply systems are applied; a review and analysis of technical solutions for pulse supercharger designs used in heat supply systems is carried out.

Results. Based on the results of the theoretical construction analysis, as well as on the experience in the practical application of individual technical solutions for pulse superchargers, provisions are determined that affect the efficiency and reliability of their operation under the working conditions with various types of heat and water supply systems. The analytical results of the pulse supercharger designs using the hydraulic shock energy applied in water supply systems reveal two main options for their technical execution, namely, a diaphragm or a piston. The significant technical solution for pulse superchargers in heat supply systems is a design in which the injection process can be implemented in conjunction with the heat exchange process. The obtained results of the conducted intellectual activity are provided with patent protection.

Conclusion. Recommendations on the use of individual pulse supercharger designs for solving specific problems in heat and water supply systems are formulated. Materials are proposed for the manufacture of some elements of the design of pulse superchargers in order to increase their reliability and energy efficiency.
