The article is about to the calculation of the main technical parameters of the directional air-hydraulic hood. It is accepted as a mathematical model of wave equations of hyperbolic type as applied to pressure pipelines of pumping stations, and analytical solutions of wave equations for different values of the polytropic exponents are proposed. Water hammer poses a danger to the normal operation of the main equipment of stations, control and measuring equipment, control devices and pressure pipelines. To damp the intensity of water hammer in the pressure pipelines of pumping stations, we have accepted an effective design of an air-hydraulic cap. When establishing the strength indicators of pressure pipelines against hydraulic shock, it is necessary to make an accurate calculation of the main parameters of the proposed design of the air - hydraulic cap. The article presents the results of analytical and experimental studies of the accepted cap design. At the same time, an analytical method is proposed for calculating the basic dimensions of the cap. The results of the proposed calculation procedure are in good corresponding with the experimental data. This confirms the reliability of the proposed analytical calculation method.
