FIELD: investigating or analyzing materials. ^ SUBSTANCE: method comprises heating, mixing, aerating and degassing of lubricant in the device for investigating the lubricants. The aerating of the lubricants is provided by their flowing through the opening of alternative cross-section where pressure drop is generated. The degassing is provided by the use of the degassing unit where, under the action of centrifugal forces, the dissolved gas is removed from the lubricant. The processes are controlled by video surveying of generation, change of sizes, shape, and concentration of gas bubbles in the lubricant as well as by readings of temperature and pressure gauges. The device comprises oil tank for temperature control with mechanical mixer, heater, and temperature gauge and pipeline with valve. The device is additionally provided with pump, throttling valve, and degassing unit. The safety valve, pump, and throttling valve are connected in series through pipeline sections. The pipeline sections provided with throttling valve and degassing unit are made of a heat-resistant transparent material and provided with temperature and pressure gauges and digital video cameras connected with the computer. ^ EFFECT: enhanced precision. ^ 2 cl, 1 dwg |
