Method for determining the structural phase high-pressure liquid centers, especially centers of highly viscous liquids

摘要

designation wysokou015bciennych structural phases and liquid, especially liquid highly viscous centres, intended to study structural properties of fluid lubrication means used in production lines or devices working in the high pressures of up to 2000 bar, is that the liquid (1), preferably oil ru0105cznikowy,subject spru0119u017caniu in high-pressure chamber (4) with a plunger (2), shall be subjected to stability in terms izotermicznych and izohorycznych by approximately 100 hours, after which, on the basis of pressure drop and the fall in the value of the module defines the production phase you basic compressibility sokociu015bnieniowej.then, in the case of the initial absence of pressure variation, the liquid (1) is subjected to rozpru0119u017caniu in high-pressure capillary (7) by continuous time measurement value due to the length of capillaries using a manometer pressure, while in mo the document of a maximum pressure differential measured pressure gauges.shall be determined in accordance with the law hegena poisseull and maximum value of a dynamic viscosity of the liquid (1), which defines the basic jump value phase structure of high-pressure liquid (1), after which shall be further, continuous in time pressure measurement at the inlet and outlet capillaries high-pressure (7) and the measurement of volume of liquid (1),then on the basis of the voltage drop in the time change curves and longitudinal viscosity value determines the decay phases of dynamic pressure and dynamic high-pressure viscosity value, in which the phase high-pressure liquid test medium it (1).
