The invention relates to the field of physics, namely, to systems for liquid and gas pressure control and adjustment, in particular, to stabilizing devices operating under overloads, including hydraulic shocks. The technical effect of the use of the invention as claimed lies in simplifying the manufacturing and assembly technologies and improving operation ease and pulsation damping efficiency. A method consisting in providing a section of said main pipeline with at least one pressure pulse stabilizer located streamwise the medium transported from a supplier to a consumer, withdrawing the pulse stream into the stabilizer as a first part, followed by a second part of the stream which is sent to an auxiliary input of the stabilizer after a delay. Potential pressure pulse sources are pre-detected on the protected pipeline section. Then, a mounting location of the stabilizer is determined based on a distance within 10 m maximum from a potential point source of pressure pulses, and based on a distance within 100-1000 m in case when at least two stabilizers are mounted at a stage for preventive purposes. The stabilizers are oriented according to point indicator outer surface toward the potential point source of pressure pulses with arrows one way directed streamwise the medium transported through stages. The stabilizers have a direct flow chamber volume designed not less than 1/3 of the larger swirl chamber volume, and a pressure chamber arranged between the case and the body and connected via the radial holes to a direct flow chamber, and a balance chamber connected via the inclined holes to the swirl chamber. The diameter of radial holes is 1.2-4 of the diameter of inclined holes. The inclined holes angles α and β are set in the range of 0-45°. The pressure in the pressure chamber and the balance chamber is adjusted through moving the pistons by means of the springs into the initial position. Various solutions are suggested for damping pressure pulses with various means, referred to the stabilizer various structural members. |
